Why Do Computers Use So Much Energy?


It’s possible they could be vastly more efficient, but for that to happen we need to better understand the thermodynamics of computing

Why Do Computers Use So Much Energy?

Microsoft is currently running an interesting set of hardware experiments. The company is taking a souped-up shipping container stuffed full of computer servers and submerging it in the ocean. The most recent round is taking place near Scotland’s Orkney Islands, and involves a total of 864 standard Microsoft data-center servers. Many people have impugned the rationality of the company that put Seattle on the high-tech map, but seriously—why is Microsoft doing this?

There are several reasons, but one of the most important is that it is far cheaper to keep computer servers cool when they’re on the seafloor. This cooling is not a trivial expense. Precise estimates vary, but currently about 5 percent of all energy consumption in the U.S. goes just to running computers—a huge cost to the economy as whole. Moreover, all that energy used by those computers ultimately gets converted into heat. This results in a second cost: that of keeping the computers from melting.

These issues don’t only arise in artificial, digital computers. There are many naturally occurring computers, and they, too, require huge amounts of energy. To give a rather pointed example, the human brain is a computer. This particular computer uses some 10–20 percent of all the calories that a human consumes. Think about it: our ancestors on the African savanna had to find 20 percent more food every single day, just to keep that ungrateful blob of pink jelly imperiously perched on their shoulders from having a hissy fit. That need for 20 percent more food is a massive penalty to the reproductive fitness of our ancestors. Is that penalty why intelligence is so rare in the evolutionary record? Nobody knows—and nobody has even had the mathematical tools to ask the question before.

There are other biological computers besides brains, and they too consume large amounts of energy. To give one example, many cellular systems can be viewed as computers. Indeed, the comparison of thermodynamic costs in artificial and cellular computers can be extremely humbling for modern computer engineers. For example, a large fraction of the energy budget of a cell goes to translating RNA into sequences of amino acids (i.e., proteins), in the cell’s ribosome. But the thermodynamic efficiency of this computation—the amount of energy required by a ribosome per elementary operation—is many orders of magnitude superior to the thermodynamic efficiency of our current artificial computers. Are there “tricks” that cells use that we could exploit in our artificial computers? Going back to the previous biological example, are there tricks that human brains use to do their computations that we can exploit in our artificial computers?

More generally, why do computers use so much energy in the first place? What are the fundamental physical laws governing the relationship between the precise computation a system runs and how much energy it requires? Can we make our computers more energy-efficient by redesigning how they implement their algorithms?

These are some of the issues my collaborators and I are grappling with in an ongoing research project at the Santa Fe Institute. We are not the first to investigate these issues; they have been considered, for over a century and a half, using semi-formal reasoning based on what was essentially back-of-the-envelope style analysis rather than rigorous mathematical arguments—since the relevant math wasn’t fully mature at the time.

This earlier work resulted in many important insights, in particular the work in the mid to late 20th century by Rolf LandauerCharles Bennett and others.

However, this early work was also limited by the fact that it tried to apply equilibrium statistical physics to analyze the thermodynamics of computers. The problem is that, by definition, an equilibrium system is one whose state never changes. So whatever else they are, computers are definitely nonequilibrium systems.  In fact, they are often very-far-from-equilibrium systems.

Fortunately, completely independent of this early work, there have been some major breakthroughs in the past few decades in the field of nonequilibrium statistical physics (closely related to a field called “stochastic thermodynamics”). These breakthroughs allow us to analyze all kinds of issues concerning how heat, energy, and information get transformed in nonequilibrium systems.

These analyses have provided some astonishing predictions. For example, we can now calculate the (non-zero) probability that a given nanoscale system will violate the second law, reducing its entropy, in a given time interval. (We now understand that the second law does not say that the entropy of a closed system cannot decrease, only that its expected entropy cannot decrease.) There are no controversies here arising from semi-formal reasoning; instead, there are many hundreds of peer-reviewed articles in top journals, a large fraction involving experimental confirmations of theoretical predictions.

Now that we have the right tools for the job, we can revisit the entire topic of the thermodynamics of computation in a fully formal manner. This has already been done for bit erasure, the topic of concern to Landauer and others, and we now have a fully formal understanding of the thermodynamic costs in erasing a bit (which turn out to be surprisingly subtle).

However, computer science extends far, far beyond counting the number of bit erasures in a given computation. Thanks to the breakthroughs of nonequilibrium statistical physics, we can now also investigate the rest of computer science from a thermodynamic perspective. For example, moving from bits to circuits, my collaborators and I now have a detailed analysis of the thermodynamic costs of “straight-line circuits.” Surprisingly, this analysis has resulted in novel extensions of information theory. Moreover, in contrast to the kind of analysis pioneered by Landauer, this analysis of the thermodynamic costs of circuits is exact, not just a lower bound.

Conventional computer science is about all about trade-offs between the memory resources and number of timesteps needed to perform a given computation. In light of the foregoing, it seems that there might be far more thermodynamic trade-offs in performing a computation than had been appreciated in conventional computer science, involving thermodynamic costs in addition to the costs of memory resources and number of timesteps. Such trade-offs would apply in both artificial and biological computers.

Clearly there is a huge amount to be done to develop this modern “thermodynamics of computation.”

Be on the lookout for a forthcoming book from the SFI Press, of contributed papers touching on many of the issues mentioned above. Also, to foster research on this topic we have built a wiki, combining lists of papers, websites, events pages, etc. We highly encourage people to visit it, sign up, and start improving it; the more scientists get involved, from the more fields, the better!

Maca Powder is a magnificent mix of fibre, carbohydrates & minerals consumed by the Incan warriors prior to battle. This superfood helped increase their fighting spirit, libido, stamina and strength. Maca powder has undoubtedly become very popular among athletes because of its rich content of nutrients.

What is Maca Powder?

 Maca powder comes from a plant native to the high Andes of Peru. It is abundant with minerals, vitamins, enzymes and essential amino acids. In Peru, it is known as ‘aphrodisiac of the Andes’.

Maca powder contains:

  • Vitamins B1, B2, C, E,
  • Minerals and trace elements including potassium, iodine, zinc, calcium, magnesium, phosphorus, iron, iodine, sulphur, bismuth, silicon, boron, tin and silica.
  • Fatty acids, complex alkaloids, and sterols.

Maca Powder Can Boost Your Sex Drive Naturally: Health Benefits

Maca powder has the ability to improve fertility. According to lab studies conducted on rats, after being fed Maca males rats increased their sperm count, and female increased egg follicle development. In Peru, Maca is used to improve strength as well as fertility.

This powder contains unique compounds as macamides and macaenes which can significantly boost your health energy levels. Moreover, Maca powder has a high content of iron, manganese, and phosphorus, and can fight fatigue.

 This incredible powder works directly on your endocrine system and helps balance the hormones in your body. It can encourage the body to produce its own hormones in order to restore balance and we all know that hormonal regulation is extremely important for almost all processes of the body. Maca powder is also beneficial for easing PMS symptoms because it provides the body with the needed nutrients so it can be able to naturally produce hormones.

It is a great source of unique alkaloids and numerous vitamins and minerals. Furthermore, it possesses adaptogenic properties which produce an adaptive response to stress, thus strengthening the body and improving stamina.

This powder also has the ability to increase libido in both men and women. According to many studies, maca powder can boost your sex drive naturally.

Science Confirms That People Absorb Energy From Others

Did it ever happen to you, when you were with a person and you felt a bad vibe, as if the person was stealing your energy?

“Everything is energy” is one of the main axioms of science, and human beings are no strangers to energy transformations.

An interesting study was conducted at the University of Bielefeld, Germany, which shows that plants can absorb energy from other plants. Olivia Bader-Lee, a physician and therapist, followed the results of this investigation.

The science that studies the behavior of energy in living things is called bioenergetics.

This research was conducted in algae, specifically in  Chlamydomonas reinhardtii. It was discovered that in addition to photosynthesis, it also have an alternative source of energy and that would be to absorb energy from other algae. The charge of this research is the German biologist Olaf Kruse, and its findings were reported on Naturesite.com.

According to Bader-Lee, our bodies are like sponges, absorbing energy that is around us. “This is exactly why there are people who feel uncomfortable when they are in a certain group with a mixture of energy and emotions”.

“The human body is very similar to a plant that sucks, absorbs the energy needed to feed your emotional state, and can energize the cells and increase the amount of cortisol and catabolize, feed the cells depending on the emotional need. ” continues Bader-Lee.

That is why many people can change their mood which leads to being nervous, stressed, angry, anxious, sad, but also happy, optimistic and laughing.

Bader-Lee says that over the centuries, man has lost that connection with nature, in which the exchange of energy could bring enormous benefits to humanity.

Ultimately, the spirit is energy, and what we call “supernatural” is nothing more than the manifestation of different energies in the world. This was known in ancient cultures from every continent, but science has decided to ignore it and only a few scientists dare to address these issues, for fear of criticism and rejection by the scientific community.

Science Confirms That People Absorb Energy From Others


A biological research team at Bielefeld University has made a groundbreaking discovery showing that plants can draw an alternative source of energy from other plants. This finding could also have a major impact on the future of bioenergy eventually providing the evidence to show that people draw energy from others in much the same way.

Members of Professor Dr. Olaf Kruse’s biological research team have confirmed for the first time that a plant, the green alga Chlamydomonas reinhardtii, not only engages in photosynthesis, but also has an alternative source of energy: it can draw it from other plants. The research findings were released this week in the online journal Nature Communications published by the renowned journal Nature.

Flowers need water and light to grow and people are no different. Our physical bodies are like sponges, soaking up the environment. “This is exactly why there are certain people who feel uncomfortable in specific group settings where there is a mix of energy and emotions,” said psychologist and energy healer Dr. Olivia Bader-Lee.

Plants engage in the photosynthesis of carbon dioxide, water, and light. In a series of experiments, Professor Dr. Olaf Kruse and his team cultivated the microscopically small green alga species Chlamydomonas reinhardtii and observed that when faced with a shortage of energy, these single-cell plants can draw energy from neighbouring vegetable cellulose instead. The alga secretes enzymes (so-called cellulose enzymes) that ‘digest’ the cellulose, breaking it down into smaller sugar components. These are then transported into the cells and transformed into a source of energy: the alga can continue to grow. ‘This is the first time that such a behaviour has been confirmed in a vegetable organism’, says Professor Kruse. ‘That algae can digest cellulose contradicts every previous textbook. To a certain extent, what we are seeing is plants eating plants’. Currently, the scientists are studying whether this mechanism can also be found in other types of alga. Preliminary findings indicate that this is the case.

“When energy studies become more advanced in the coming years, we will eventually see this translated to human beings as well,” stated Bader-Lee. “The human organism is very much like a plant, it draws needed energy to feed emotional states and this can essentially energize cells or cause increases in cortisol and catabolize cells depending on the emotional trigger.”

Bader-Lee suggests that the field of bioenergy is now ever evolving and that studies on the plant and animal world will soon translate and demonstrate what energy metaphysicians have known all along — that humans can heal each other simply through energy transfer just as plants do. “Human can absorb and heal through other humans, animals, and any part of nature. That’s why being around nature is often uplifting and energizing for so many people,” she concluded.

HERE ARE FIVE ENERGY TOOLS TO USE TO CLEAR YOUR SPACE AND PREVENT ENERGY DRAINS WHILE RELEASING PEOPLE’S ENERGY:

Stay centered and grounded. If you are centered within your spiritual self (instead of your analyzer or ego) you will sense right away when something has moved into your space. If you are fully grounded, you can easily release other people’s energy and emotions down your grounding cord with your intention.

Be in a state of non-resistance. What we resists sticks. If you feel uncomfortable around a certain person or in a group, don’t go into resistance as a way to protect yourself as this will only keep foreign energy stuck in your space. Move into a state of non-resistance by imagining that your body is clear and translucent like clear glass or water. This way, if someone throws some invalidation at you, it will pass right through you.

Own your personal aura space. We each have an energetic aura surrounding our body. If we don’t own this personal space we are vulnerable to foreign energy entering it. Become aware of your aura boundaries (about an arms length away from your body all the way around, above and below) as a way to own your personal space.

Give yourself an energy cleanse. The color gold has a high vibration which is useful for clearing away foreign energy. Imagine a gold shower nozzle at the top of your aura (a few feet above your head) and turn it on, allowing clear gold energy to flow through your aura and body space and release down your grounding. You will immediately feel cleansed and refreshed.

Call back your energy. When we have our energy in our own space there is less room for other’s energy to enter. But as we focus on other people and projects we sometimes spread our energy around. Create an image of a clear gold sun several feet above your head and let it be a magnet, attracting all of your energy back into it (and purifying it in the gold energy). Then bring it down through the top of your aura and into your body space, releasing your energy back into your personal space.

Maca: Superfood for Energy, Stamina and Libido


Maca: Superfood for Energy, Stamina and Libido

Thanks to the efforts of a single Peruvian researcher, a neglected and little known ancient plant was saved from certain extinction about 50 years ago.  Today that resurrected root is considered a superfood that improves energy, stamina and libido, and can help menopausal women balance their hormones naturally.

Maca is a root vegetable (belonging to the Brassica family) that has been cultivated in the Peruvian Andes for over 2,600 years.  Growing at about 10,000 feet above sea level, it is the highest altitude crop in the world.

Back from the brink, maca is enjoying a resurgence in popularity as a result of the research ofGloria Chacon de Popovici, Ph.D., a Peruvian biologist, who conducted studies beginning in the 1960’s showing that maca increases fertility in rats, dogs, guinea pigs, rams, cows and humans.

Among traditional peoples in Peru, maca has long been treasured for it aphrodisiac qualities.  Modern research is now lending scientific support to the wisdom of the ancients.

Studies in men have found that maca supplementation can improve a man’s subjective perception of his general and sexual well-being, as well as increase his sexual desire.

In postmenopausal women, it’s been found to reduce psychological symptoms, including anxiety and depression, and improve libido.

Although maca grabs headlines for its aphrodisiac qualities and its reputation as a natural Viagra, it has many other health benefits.

Maca is an adaptogen

According to David “Avocado” Wolfe, author of Superfoods: The Food and Medicine of the Future, maca is a powerful adaptogen or nutritive substance that counters adverse sources of stress and allows the body to adapt naturally to stressful conditions. Adaptogens also help to improve the body’s natural balance or homeostasis.

As a result Wolfe says, maca “increases energy, endurance, oxygen in the blood, physical strength, neurotransmitter production, and libido. It supports the endocrine system, the adrenals, and the thyroid, typically improves one’s mood, and helps support healthy hormone production.”

Maca has been recommended for everything from impotence and infertility to depression, hot flashes, stress and memory loss.

How does maca work?

How does maca work its magic? One way is that it stimulates the hypothalamus and pituitary glands which in turn regulate the other glands in the body, and can bring balance to the adrenal, thyroid, pancreatic, ovarian and testicular glands.

Typically dried and powdered, maca is rich in calcium, magnesium, phosphorous, potassium, sulfur, sodium and iron as well as vitamins B1 (thiamin), B2 (riboflavin), C and E. It also contains zinc, iodine, copper, selenium, manganese and silicon.

Compared to the potato which also originated in the Andes, maca contains five times more protein and four times more fiber.

How much maca can you take? 

Wolfe recommends 1 to 2 tablespoons of maca daily and points out that studies have shown no toxicity or pharmacological effects.

Maca has a butterscotch aroma but a funky turnip flavor that can be a little strong for some. Don’t let that stop you.  Add powdered maca to smoothies, salad dressings, soups, broth, tea or coffee.

When buying maca, look for the organic, raw, dried, powdered root. You can find it in local health foods or on-line.

How to take a power nap at work, even if your office doesn’t have nap rooms


If naps are so good for us, then why are they so hard to take at work?
work nap station

A nap a day could keep the doctor, and therapist, away – so why are they so impossible to take at work?Sleep deprivation is linked to a lot of scary things, like Alzheimer’s disease, depression, memory problems, and cancer – and while a nap won’t completely make up for hours of lost sleep, scientists agree that a power nap can do wonders.

Studies have shown that naps improve immune health, energy, cognitive function, and emotional control – and all you really need is 10 minutes.

But while napping may be an effective strategy to counteract negative emotional, cognitive, and physical consequences, the problem with recommending that we take naps at work, as psychologist Dr. Ron Friedman previously told Business Insider, is that this isn’t entirely practical.

The author of “The Best Place to Work” has long been a proponent for on-the-job napping, but he said that he debated whether or not to recommend this in his book, since many struggle with office-space constraints and cultural attitudes about napping.

“Particularly in American culture, we like to believe that productivity is a function of effort, and that if we work hard we’ll produce,” he said. “But the reality is that we have a biological need for rest no different or less important than our need for food or water.”

So is there a way to reconcile our biological need for rest and napping constraints at work? Arianna Huffington believes there is.

“There will always be times when we don’t get enough sleep: we have a sick child, we have a big deadline, we just toss and turn. My advice there is, as soon as you can, get a nap,” “The Sleep Revolution” author tells Business Insider.

Huffington Post Nap Room

A Huffington Post nap pod.

She says:

The truth is, I predict in the next few years nap rooms are going to be as universal as conference rooms, because the science now is conclusive about the value of napping. Do you want exhausted employees being exhausted during the day, or do you want them to go have a 20-minute nap and literally have another day ahead of them? Because that’s how restorative a nap is.

For those who don’t have nap rooms in their office, Huffington suggests gathering your forces and lobbying for a nap room.

Until there is one, she suggests asking an office manager to ensure that couches are placed in as private a place as possible.

“Then have your kit with your earplugs and your eye mask and you can lie on that couch,” she says.

If there isn’t a couch in a private-enough space – pending manager approval – she suggests bringing a yoga mat to work, finding the most private space in the office, and napping on the mat.

“There are ways to make that happen if you believe that it will actually make you more effective, more productive, and happier,” Huffington says.

She also says:

Luckily, I think the stigma around napping is very fast being eliminated. I know when we launched our nap rooms at the Huffington Post in 2011, there was an enormous amount of skepticism and eye-rolling, and people were reluctant to be seen in the middle of the afternoon walking into a nap room. But that’s no longer the case – the nap rooms are always full, and I think in fact we need to open a third one.

Friedman says that eliminating the stigma around napping comes down to leaders modeling better attitudes about sleep. Huffington would agree.

She says:

I have a couch in my office, and I have a glass wall, so when I wanted to have a nap – I didn’t want to use the nap room so I wouldn’t take it away from others – I would nap on my couch and close the curtain. Now I no longer close the curtain. And that has helped eliminate the stigma, to show that you can nap publicly, and, actually, it’s a performance-enhancement tool, and it should be celebrated as such.

This Interview With Nikola Tesla From 1899 Reveals His Extraordinary Personality


N.Tesla

Very interesting interview Nikola Tesla and John Smith in which he said: Everything is the Light. In one of its rays is the fate of nations, each nation has its own ray in that great light source, which we see as the Sun. And remember: no one man that existed did not die.

JOURNALIST: Mr. Tesla, you have gained the glory of the man who got involved in the cosmic processes. Who are you, Mr. Tesla?
TESLA: It is a right question, Mr. Smith, and I will try to give you the right answer to it.

JOURNALIST: Some say you’re from the country of Croatia, from the area called Lika, where together with the people are growing trees, rocks and starry sky. They say that your home village is named after the mountain flowers, and that the house, where you were born, is next to the forest and the church.
TESLA: Really, all it true. I’m proud of my Serbian origin and my Croatian homeland.

JOURNALIST: Futurists say that the Twenty-and Twenty First Century was born in head of Nikola Tesla. They celebrate conversely magnetic field and sing hymns to Inductions engine. Their creator was called the hunter who caught the light in his net from the depths of the earth, and the warrior who captured fire from heaven. Father of alternating current will make the Physics and Chemistry dominate half the world. Industry will proclaim him as their supreme saint, a banker for the largest benefactors. In the laboratory of Nikola Tesla for the first time is broken atom. There is created a weapon that causes the earthquake vibrations. There are discovered black cosmic rays. Five races will pray to him in the Temple of the future, because they had taught a great secret that Empedocles elements can be watered with the life forces from the ethers.
TESLA: Yes, these are some of my most important discoveries. I’m a defeated man. I have not accomplished the greatest thing I could.

JOURNALIST: What is it, Mr. Tesla?
TESLA: I wanted to illuminate the whole earth. There is enough electricity to become a second sun. Light would appear around the equator, as a ring around Saturn.
Mankind is not ready for the great and good. In Colorado Springs I soaked the earth by electricity. Also we can water the other energies, such as positive mental energy. They are in the music of Bach or Mozart, or in the verses of great poets. In the Earth’s interior, there are energy of Joy, Peace and Love. Their expressions are a flower that grows from the Earth, the food we get out of her and everything that makes man’s homeland. I’ve spent years looking for the way that this energy could influence people. The beauty and the scent of roses can be used as a medicine and the sun rays as a food. Life has an infinite number of forms, and the duty of scientists is to find them in every form of matter. Three things are essential in this. All that I do is a search for them. I know I will not find them, but I will not give up on them.

JOURNALIST: What are these things?
TESLA: One issue is food. What a stellar or terrestrial energy to feed the hungry on Earth? With what wine watered all thirsty, so that they can cheer in their heart and understand that they are Gods?
Another thing is to destroy the power of evil and suffering in which man’s life passes! They sometimes occur as an epidemic in the depths of space. In this century, the disease had spread from Earth in the Universe.
The third thing is: Is there an excess Light in the Universe? I discovered a star that by all the astronomical and mathematical laws could disappear, and that nothing seems to be modified. This star is in this galaxy. Its light can occur in such density that fits into a sphere smaller than an apple, a heavier than our Solar System. Religions and philosophies teach that man can become the Christ, Buddha and Zoroaster. What I’m trying to prove is wilder, and almost unattainable. This is what to do in the Universe so every being is born as Christ, Buddha or Zoroaster.
I know that gravity is prone to everything you need to fly and my intention is not to make flying devices (aircraft or missiles), but teach individual to regain consciousness on his own wings … Further; I am trying to awake the energy contained in the air. There are the main sources of energy. What is considered as empty space is just a manifestation of matter that is not awakened. No empty space on this planet, nor in the Universe.. In black holes, what astronomers talk about, are the most powerful sources of energy and life.

JOURNALIST: On the window of your room in hotel “Valdorf-Astoria”, on the thirty-third floor, every morning, the birds arrive.
TESLA: A man must be sentimental towards the birds. This is because of their wings. Human had them once, the real and visible!

JOURNALIST: You have not stopped flying since those distant days in Smiljan!
TESLA: I wanted to fly from the roof and I fell: Children’s calculations could be wrong. Remember, the youth wings have everything in life!

JOURNALIST: Have you ever married? It is not known that you have affection for love or for a woman. Photos from the youth show you were handsome man.
TESLA: Yes. I did not. There are two views: a lot affection or not at all. The center serves to rejuvenate human race. Women for certain people nurtures and strengthen its vitality and spirit. Being single does the same to other people. I chose that second path.

JOURNALIST: Your admirers are complaining that you attacking relativity. The strange is your assertion that the matter has no energy. Everything is imbued with energy, where it is?
TESLA: First was energy, then matter.

JOURNALIST: Mr. Tesla, it’s like when you said that you were born by your father, and not on you.
TESLA: Exactly! What about the birth of the Universe? Matter is created from the original and eternal energy that we know as Light .It shone, and there have been appear star, the planets, man, and everything on the Earth and in the Universe. Matter is an expression of infinite forms of Light, because energy is older than it. There are four laws of Creation. The first is that the source of all the baffling, dark plot that the mind cannot conceive, or mathematics measure. In that plot fit the whole Universe. The second law is spreading a darkness, which is the true nature of Light, from the inexplicable and  it’s transformed into the Light. The third law is the necessity of the Light to become a matter of Light. The fourth law is: no beginning and no end; three previous laws always take place and the Creation is eternal.

JOURNALIST: In the hostility to the theory of relativity you go so far, that you hold lectures against its Creator at your birthday parties..
TESLA: Remember, it is not curved space, but the human mind which cannot comprehend infinity and eternity! If relativity has been clearly understood by its Creator, he would gain immortality, even yet physically, if he is pleased.
I am part of a light, and it is the music. The Light fills my six senses: I see it, hear, feel, smell, touch and think. Thinking of it means my sixth sense. Particles of Light are written note. O bolt of lightning can be an entire sonata. A thousand balls of lightening is a concert.. For this concert I have created a Ball Lightning, which can be heard on the icy peaks of the Himalayas.
About Pythagoras and mathematics a scientist may not and must not infringe of these two. Numbers and equations are signs that mark the music of the spheres. If Einstein had heard these sounds, he would not create theories of relativity. These sounds are the messages to the mind that life has meaning, that the Universe exists in perfect harmony, and its beauty is the cause and effect of Creation. This music is the eternal cycle of stellar heavens. The smallest star has completed composition and also, part of the celestial symphony. The man’s heartbeats are part of the symphony on the Earth. Newton learned that the secret is in geometric arrangement and motion of celestial bodies. He recognized that the supreme law of harmony exists in the Universe. The curved space is chaos, chaos is not music. Einstein is the messenger of the time of sound and fury.

JOURNALIST: Mr. Tesla, do you hear that music?
TESLA: I hear it all the time. My spiritual ear is as big as the sky we see above us. My natural ear I increased by the radar. According to the Theory of Relativity, two parallel lines will meet in infinity. By that Einstein’s curved will straighten. Once created, the sound lasts forever. For a man it can vanish, but continues to exist in the silence that is man’s greatest power. No, I have nothing against Mr. Einstein. He is a kind person and has done many good things, some of which will become part of the music. I will write to him and try to explain that the ether exists, and that its particles are what keep the Universe in harmony, and the life in eternity.

JOURNALIST: Tell me, please, under what conditions Angel adopt on the Earth?
TESLA: I have ten of them. Keep good records vigilant.

JOURNALIST: I will document all your words, Dear Mr. Tesla.
TESLA: The first requirement is a high awareness of its mission and work to be done. It must, if only dimly, exist in the early days. Let us not be falsely modest; Oak knows that it is oak tree, a bush beside him being a bush. When I was twelve, I have been sure I will get to Niagara Falls. For most of my discoveries I knew in my childhood that I will achieve them, although not entirely apparent … The second condition to adapt is determination. All that I might, I finished.

JOURNALIST: What is the third condition of adjustment, Mr. Tesla?
TESLA: Guidance for all the vital and spiritual energies in labor. Therefore purification of the many effects and needs that man has. I therefore have not lost anything, but just gained.
So I enjoyed every day and night. Write down: Nikola Tesla was a happy man…
The fourth requirement is to adjust the physical assembly with a work.

JOURNALIST: What do you mean, Mr. Tesla?
TESLA: First, the maintenance of the assembly. Man’s body is a perfect machine. I know my circuit and what’s good for him. Food what nearly all people eat, to me it is harmful and dangerous. Sometimes I visualize that chefs in the world are all in conspiracy against me … Touch my hand.

JOURNALIST: It was cold.
TESLA: Yes. Bloodstream can be controlled, and many processes in and around us. Why are you frightened young man?

JOURNALIST: It’s a story that Mark Twain wrote a mysterious stranger, that wonderful book of Satan, inspired by you.
TESLA: The word “Lucifer” is more charming. Mr. Twain likes to joke. As a child I was healed once by reading his books. When we met here and told him about, he was so touched that he cried. We became friends and he often came to my lab. Once he requested to show him a machine that by vibration provokes a feeling of bliss. It was one of those inventions for entertainment, what I sometimes like to do. I warned Mr. Twain as not to remain under these vibrations. He did not listen and stayed longer. It ended by being, like a rocket, holding pants, darted into a certain room. It was a diabolically funny, but I kept the seriousness.
But, to adjust the physical circuit, in addition to food, dream is very important . From a long and exhausting work, which required superhuman effort, after one hour of sleep I’d be fully recovered. I gained the ability to manage sleep, to fell asleep and wake up in the time which I have designated. If I do something what I do not understand, I force myself to think about it in my dream, and thus find a solution.
TESLA: The fifth condition of adjustment is memory. Perhaps in the most people, the brain is keeper of knowledge about the world and the knowledge gained through the life. My brain is engaged in more important things than remembering, it is picking what is required at a given moment. This is all around us. It should only be consumed. Everything that we once saw, hear, read and learn, accompanies us in the form of light particles. To me, these particles are obedient and faithful. Goethe’s Faust, my favorite book, I learned by heart in German as a student, and now it can all recite. I held my inventions for years  ‘in my head ”, and only then I realized them.

JOURNALIST: You often mentioned the power of visualization.
TESLA: I might have to thank to visualization for all that I invented. The events of my life and my inventions are real in front of my eyes, visible as each occurrence or the item. In my youth I was frightened of not knowing what it is, but later, I learned to use this power as an exceptional talent and gift. I nurtured it, and jealously guarded. I also made corrections by visualization on most of my inventions, and finish them that way, by visualization I mentally solve complex mathematical equations. For that gift I have, I will receive rank High Lama in Tibet.
My eyesight and hearing are perfect and, dare to say, stronger than other people. I hear the thunder of a hundred fifty miles away, and I see colors in the sky that others cannot see. This enlargement of vision and hearing, I had as a child. Later I consciously developed.

JOURNALIST: In youth you have several times been seriously ill. Is it a disease and a requirement to adapt?
TESLA: Yes. It is often the result of a lack of exhaustion or vital force, but often the purification of mind and body from the toxins that have accumulated. It is necessary that a man suffers from time to time. The source of most disease is in the spirit. Therefore the spirit and can cure most diseases. As a student I got sick of cholera which raged in the region of Lika. I was cured because my father finally allowed me to study technology, which was my life. Illusion for me was not a disease, but the mind’s ability to penetrate beyond the three dimensions of the earth. I had them all my life, and I have received them as all other phenomena around us. Once, in childhood, I was walking along the river with Uncle and said: ”From the water will appear the trout, I’ll throw a stone and it is cut.” That’s what happened. Frightened and amazed, his uncle cried: ”Bade retro Satan’s!” He was an educated and he spoke in Latin … I was in Paris when I saw my mother’s death. In the sky, full of light and music floated are wonderful creatures. One of them had a mother’s character, who was looking at me with infinite love. As the vision disappeared, I knew that my mother died.

JOURNALIST: What is the seventh adjustment, Mr. Tesla?
TESLA: The knowledge of how the mental and vital energy transform into what we want, and achieve control over all feelings. Hindus call it Kundalini Yoga. This knowledge can be learned, for what they need many years or is acquired by birth. The most of them I acquired by birth. They are in the closest connection with a sexual energy that is after the most widespread in the Universe. The woman is the biggest thief of that energy, and thus the spiritual power. I’ve always knew that and was alerted. Of myself I created what I wanted: a thoughtful and spiritual machine.

JOURNALIST: A ninth adjustment, Mr. Tesla?
TESLA: Do everything that any day, any moment, if possible, not to forget who we are and why we are on Earth. Extraordinary people who are struggling with illness, privation, or the society which hurts them with its stupidity, misunderstanding, persecution and other problems which the country is full of a swamps with insects, leaves behind unclaimed until the end of the work. There are many fallen angels on Earth.

JOURNALIST: What is the tenth adaptation?
TESLA: It is most important. Write that Mr. Tesla played. He played the whole of his life and enjoyed it.

JOURNALIST: Mr. Tesla! Whether it relates to your findings and your work? Is this a game?
TESLA: Yes, dear boy. I have so loved to play with electricity! I always cringe when I hear about the one also the Greek who stole fire. A terrible story about studding, and eagles peck at his liver. Did Zeus did not have enough lightning and thunder, and was damaged for one fervor? There is some misunderstanding … Lightning are the most beautiful toys that can be found. Do not forget that in your text stand out: Nikola Tesla was the first man who discovered lightning.

JOURNALIST: Mr. Tesla, you’re just talking about angels and their adaptation to the Earth.
TESLA: Am I? This is the same. You could write this: he dared to take upon himself the prerogatives of Indri, Zeus and Peron. Imagine one of these gods in a black evening suit, with the bowler hat and wearing white cotton gloves prepares lightning, fires and earthquakes to the New York City elite!

JOURNALIST: Readers love the humor of our paper. But you confuse me stating that your findings, which have immense benefits for the people, representing the game. Many will frown on it.
TESLA: Dear Mr. Smith, the trouble is that people are too serious. If they were not, they would be happier and much longer would have lived. Chinese proverb says that the seriousness reduces life. Visiting the inn Tai Pe guessed that he visits the Imperial Palace. But that the newspaper readers would not have frowned, let’s get back to things which they consider important.

JOURNALIST: They would love to hear what your philosophy is.
TESLA: Life is a rhythm that must be comprehended. I feel the rhythm and direct on it and pamper in it. It was very grateful and gave me the knowledge I have. Everything that lives is related to a deep and wonderful relationship: man and the stars, amoebas’ and the sun, the heart and the circulation of an infinite number of worlds. These ties are unbreakable, but they can be tame and to propitiate and begin to create new and different relationships in the world, and that does not violate the old. Knowledge comes from space; our vision is its most perfect set. We have two eyes: the earthly and spiritual. It is recommended that it become one eye. Universe is alive in all its manifestations, like a thinking animal. Stone is a thinking and sentient being, such as plant, beast and a man. A star that shines asked to look at, and if we are not a sizeable self-absorbed we would understand its language and message. His breathing, his eyes and ears of the man must comply with breathing, eyes and ears of the Universe.

JOURNALIST: As you say this, it seems to me like I hear Buddhist texts, words or Taoist Parazulzusa.
TESLA: That’s right! This means that there is general knowledge and truth that man has always possessed. In my feeling and experience, the Universe has only one substance and one supreme energy with an infinite number of manifestations of life. The best thing is that the discovery of a secret nature, reveals the other. One cannot hide, there are around us, but we are blind and deaf to them. If we emotionally tie ourselves to them, they come to us themselves. There are a lot of apples, but one Newton. He asked for just one apple that fell in front of him.

JOURNALIST: A question that might be set at the beginning of this conversation. What was Electricity for you, Dear Mr. Tesla?
TESLA: Everything is Electricity. First was the light, endless source from which points out material and distribute it in all forms that represent the Universe and the Earth with all its aspects of life. Black is the true face of Light, only we do not see this. It is remarkable grace to man and other creatures. One of its particles possesses light, thermal, nuclear, radiation, chemical, mechanical and an unidentified energy. It has the power to run the Earth with its orbit. It is true Archimedean lever.

JOURNALIST: Mr. Tesla, you’re too biased towards electricity.
TESLA: Electricity I am. Or, if you wish, I am the electricity in the human form. You are Electricity; too Mr. Smith, but you do not realize it.

JOURNALIST: Is it thus your ability to allow fails of electricity of one million volts trough your body?
TESLA: Imagine a gardener who is attacked by herbs. This would indeed be crazy. Man’s body and brain are made from a large amount energy; in me there is the majority of electricity. The energy that is different in everyone is what makes the human ”I” or ”soul”. For other creatures to their essence, “soul” of the plant is the “soul” of minerals and animals. Brain function and death is manifested in light. My eyes in youth were black, now blue, and as time goes on and strain the brain gets stronger, they are closer to white. White is the color of heaven. Through my window one morning, landed a white dove, which I fed. She wanted to bring me a word that she was dying. From her eyes the light jets were coming out. Never in the eyes of any creature had I not seen so much light, as in that pigeon.

JOURNALIST: Personnel in your lab speak about flashes of light, flames and lightning that occur if you are angry or into kind of risk.
TESLA: It is the psychic discharge or a warning to be alert. The light was always on my side. Do you know how I discovered the rotating magnetic field and induction motor, which made me became famous when I was twenty-six? One summer evening in Budapest, I watched with my friend Sigetijem sunset. Thousands of fire was turning around in thousands of flaming colors. I remembered Faust and recited his verses and then, as in a fog, I saw spinning magnetic field, and induction motor. I saw them in the sun!

JOURNALIST: Hotel service telling that at the time of lightning you isolate into the room and talk to yourselves.
TESLA: I talk with lightning and thunder.

JOURNALIST: With them? What language, Mr.Tesla?
TESLA: Mostly my native language. It has the words and sounds, especially in poetry, what is suitable for it.

JOURNALIST: Readers of our magazine would be very grateful if you would interpret that.
TESLA: The sound does not exist only in the thunder and lightning, but, in transformation into the brightness and color. A color can be heard. Language is of the words, which means that it is from the sounds and colors. Every thunder and lightning are different and have their names. I call some of them by the names of those who were close in my life, or by those whom I admire. In the sky brightness and thunder live my mother, sister, brother Daniel, a poet Jovan Jovanovic Zmaj and other persons of Serbian history. Names such AsIsaiah, Ezekiel, Leonardo, Beethoven, Goya, Faraday, Pushkin and all burning fires mark shoals and tangles of lightning and thunder, which does not stop all night bringing to the Earth precious rain and burning trees or villages. There is lightning and thunder, and they are the brightest and most powerful, that will not vanish. They are coming back and I recognize them among the thousands.

JOURNALIST: For you, science or poetry is the same?
TESLA: These are the two eyes of one person. William Blake was taught that the Universe was born from the imagination, that it maintains and it will exist as long as there is a last man on the Earth. With it was a wheel to which astronomers can collect the stars of all galaxies. It is the creative energy identical to the light energy.

JOURNALIST: Imagination is more real to you than life itself?
TESLA: It gives birth to the life. I have fed by my taught; I’ve learned to control emotions, dreams and visions. I have always cherished, as I nurtured my enthusiasm. All my long life I spent in ecstasy. That was the source of my happiness. It helped me during all these years to bear with work, which was enough for the five lives. The best is to work at night, because the stellar light, and close bond.

JOURNALIST: You said that I am, like every being, the Light. This flatter me, but I confess, I do not quite understand.
TESLA: Why would you need to understand, Mr. Smith? Suffice it to believe it. Everything is light. In one its ray is the fate of nations, each nation has its own ray in what great light source we see as the sun. And remember: no one who was there did not die. They transformed into the light, and as such exist still. The secret lies in the fact that the light particles restore their original state.

JOURNALIST: This is the resurrection!
TESLA: I prefer to call it: return to a previous energy. Christ and several others knew the secret. I am searching how to preserve human energy. It is forms of Light, sometimes straight like heavenly light. I have not looked for it for my own sake, but for the good of all. I believe that my discoveries make people’s lives easier and more bearable, and channel them to spirituality and morality.

JOURNALIST: Do you think that time can be abolished?
TESLA: Not quite, because the first feature of the energy is that it transforms. It is in perpetual transformation, as clouds of Taoists. But it is possible to leverage the fact that a man preserves consciousness after the earthly life. In every corner of the universe exist energy of life; one of them is immortality, whose origin is outside of man, waiting for him. The universe is spiritual; we are only half that way. The Universe is more moral than us, because we do not know his nature and how to harmonize our lives with it. I am not scientist, science is perhaps the most convenient way to find the answer to the question that always haunt me, and which my days and nights turned into fire.

JOURNALIST: What’s the matter?
TESLA: How are your eyes brightened! … What I wanted to know is: what happens to a falling star as the sun goes out? Stars fall like dust or seed in this or in other worlds, and the sun be scattered in our minds, in the lives of many  beings,  what will be reborn as a new light, or cosmic wind scattered in infinity. I understand that this is necessary included in the structure of the Universe. The thing is, though, is that one of these stars and one of these suns, even the smallest, preserves.

JOURNALIST: But, Mr. Tesla, you realize that this is necessary and is included in the constitution of the world!
TESLA: When a man becomes concuss; that his highest goal must be to run for a shooting star, and tries to capture it; shall understand that his life was given to him because of this and will be saved. Stars will eventually be capable to catch!

JOURNALIST: And what will happen then?
TESLA: The creator will laugh and say: ”It fall only that you chase her and grab her.”

JOURNALIST: Isn’t all of this contrary to the cosmic pain, which so often you mention in your writings? And what is it cosmic pain?
TESLA: No, because we are on Earth … It is an illness whose existence the vast majority of people are not aware of. Hence, many other illnesses, suffering, evil, misery, wars and everything else what makes human life an absurd and horrible condition. This disease cannot be completely cured, but awareness shall make it less complicated and hazardous. Whenever one of my close and dear people were hurt, I felt physical pain. This is because our bodies are made as of similar material, and our soul related with unbreakable strands. Incomprehensible sadness that overwhelmed us at times means that somewhere, on the other side on this planet, a child or generous man died. The entire Universe is in certain periods sick of itself, and of us. Disappearance of a star and the appearance of comets affect us more than we can imagine. Relationships among the creatures on the Earth are even stronger, because of our feelings and thoughts the flower will scent even more beautiful or will fall in silence. These truths we must learn in order to be healed. Remedy is in our hearts and evenly, in the heart of the animals that we call the Universe.

Solar panels can power the world


Reuters / Jorge Cabrera

The world’s population currently consumes 15 terawatts of power from various energy sources, according to the Economist. Despite making up less than 5 percent of the world’s population, Americans use 26 percent of the world’s power.

The publication, by the Massachusetts Institute of Technology, shows that no revolution in solar energy needs to take place, as scientists already have everything they need to harness the energy of the sun and turn it into electricity, though minor tweaks may help to improve efficiency.

The US, for example, generates less than 1 percent of its energy from solar power. This is something the researchers are looking to change.

 

“Our objective has been to assess solar energy’s current and potential competitive position and to identify changes in US government policies that could more efficiently and effectively support its massive deployment over the long-term, which we view as necessary,” Robert Armstrong, the director of MIT Energy Initiative, said in a statement.

The Topaz solar farm in California went online at the end of 2014. It generates 500 megawatts of energy, which is enough energy to power at least 160,000 homes. A terawatt is 1 million megawatts of energy.

The company behind the project, First Solar, uses 9 million solar panels to generate electricity. Crucially, it also eliminates over 350,000 tons of CO2 every year, Techspot reports.

“Solar electricity generation is one of very few low-carbon energy technologies with the potential to grow to very large scale. As a consequence, massive expansion of global solar generating capacity to multi-terawatt scale is very likely an essential component of a work-able strategy to mitigate climate change risk,” the MIT report said.

The study has emphasized the need for more research at a federal level, as well as more development support to help to advance low cost and large scale electricity storage technologies.

Battery technology is expected to be a crucial part of the future development of solar power energy, as the batteries can be used to store electricity during peak production and then dispense it at times when there is no sunshine.

The CEO of Tesla industries, Elon Musk, has been a big advocate of trying to develop better batteries that could help to store electricity.

“Our goal here is to fundamentally change the way the world uses energy,” Musk said on April 30, Bloomberg reported. “We’re talking at the terawatt scale. The goal is the complete transformation of the entire energy infrastructure of the world.”

The ability to get funding is out there. For example, the International Monetary Fund has calculated that the fossil fuel industries are receiving $5.3 trillion a year in subsidies, which is the equivalent to $10 million every minute. This is a figure that those looking to promote solar power can only dream of.

The authors of the MIT publication believe that the production of solar power will only increase if carbon dioxide emissions become costly. They admit this is unlikely to happen without a drastic rethink in US government policy.

“The main goal of US solar policy should be to build the foundation for a massive scale-up of solar generation over the next few decades,” the report said.

The researchers point to the example of Germany as a standout in pursuing green energy. In 1991, Berlin adopted a Feed-in Tariff scheme which was a rebate scheme to encourage the production of low carbon source energy.

The scheme was so successful that by 2013 Germany was producing 45 percent of solar energy in the EU, and 27 percent of solar energy around the globe, despite the fact that the country is not renowned for having a year-round sunny climate.

‘Optical fibre’ made out of thin air .


Scientists say they have turned thin air into an ‘optical fibre’ that can transmit and amplify light signals without the need for any cables.

In a proof-of-principle experiment they created an “air waveguide” that could one day be used as an instantaneous optical fibre to any point on earth, or even into space.

The findings, reported in the journal Optica, have applications in long range laser communications, high-resolution topographic mapping, air pollution and climate change research, and could also be used by the military to make laser weapons.

“People have been thinking about making air waveguides for a while, but this is the first time it’s been realised,” says Professor Howard Milchberg of the University of Maryland, who led the research, which was funded by the US military and National Science Foundation.

Lasers lose intensity and focus with increasing distance as photons naturally spread apart and interact with atoms and molecules in the air.

Fibre optics solves this problem by beaming the light through glass cores with a high refractive index, which is good for transmitting light.

The core is surrounded by material with a lower refractive index that reflects light back in to the core, preventing the beam from losing focus or intensity.

Fibre optics, however, are limited in the amount of power they can carry and the need for a physical structure to support them.

Light and air

Milchberg and colleagues’ made the equivalent of an optical fibre out of thin air by generating a laser with its light split into a ring of multiple beams forming a pipe.

They used very short and powerful pulses from the laser to heat the air molecules along the beam extremely quickly.

Such rapid heating produced sound waves that took about a microsecond to converge to the centre of the pipe, creating a high-density area surrounded by a low-density area left behind in the wake of the laser beams.

“A microsecond is a long time compared to how far light propagates, so the light is gone and a microsecond later those sound waves collide in the centre, enhancing the air density there,” says Milchberg.

The lower density region of air surrounding the centre of the air waveguide had a lower refractive index, keeping the light focused.

“Any structure [even air] which has a higher density will have a higher index of refraction and thereby act like an optical fibre,” says Milchberg.

Amplified signal

Once Milchberg and colleagues created their air waveguide, they used a second laser to spark the air at one end of the waveguide turning it into plasma.

An optical signal from the spark was transmitted along the air waveguide, over a distance of a metre to a detector at the other end.

The signal collected by the detector was strong enough to allow Milchberg and colleagues to analyse the chemical composition of the air that produced the spark.

The researchers found the signal was 50 per cent stronger than a signal obtained without an air waveguide.

The findings show the air waveguide can be used as a “remote collection optic,” says Milchberg.

“This is an optical fibre cable that you can reel out at the speed of light and place next to [something] that you want to measure remotely, and have the signal come all the way back to where you are.”

Australian expert Professor Ben Eggleton of the University of Sydney says this is potentially an important advance for the field of optics.

“It’s sort of like you have an optical fibre that you can shine into the sky, connecting your laser to the top of the atmosphere,” says Eggleton.

“You don’t need big lenses and optics, it’s already guided along this channel in the atmosphere.”

 

14 Bad Habits That Drain Your Energy .


Lack of sleep isn’t the only thing sapping your energy. Little things you do (and don’t do) can exhaust you both mentally and physically, which can make getting through your day a chore. Here, experts reveal common bad habits that can make you feel tired, plus simple lifestyle tweaks that will put the pep back in your step.

You skip exercise when you’re tired

Skipping your workout to save energy actually works against you. In a University of Georgia study, sedentary but otherwise healthy adults who began exercising lightly three days a week for as little as 20 minutes at a time reported feeling less fatigued and more energized after six weeks. Regular exercise boosts strength and endurance, helps make your cardiovascular system run more efficiently, and delivers oxygen and nutrients to your tissues. So next time you’re tempted to crash on the couch, at least go for a brisk walk—you won’t regret it.

 

You don’t drink enough water

Being even slightly dehydrated—as little as 2% of normal fluid loss—takes a toll on energy levels, says Amy Goodson, RD, a dietitian for Texas Health Ben Hogan Sports Medicine. Dehydration causes a reduction in blood volume, explains Goodson, which makes the blood thicker. This requires your heart to pump less efficiently, reducing the speed at which oxygen and nutrients reach your muscles and organs. To calculate your normal fluid needs, take your weight in pounds, divide in half and drink that number of ounces of fluid a day, Goodson recommends.

You’re not consuming enough iron

An iron deficiency can leave you feeling sluggish, irritable, weak, and unable to focus. “It makes you tired because less oxygen travels to the muscles and cells,” says Goodson. Boost your iron intake to reduce your risk of anemia: load up on lean beef, kidney beans, tofu, eggs (including the yolk), dark green leafy vegetables, nuts, and peanut butter, and pair them with foods high in vitamin C (vitamin C improves iron absorption when eaten together), suggests Goodson. Note: an iron deficiency may be due to an underlying health problem, so if you’re experiencing these symptoms of iron deficiency, you should visit your doc.

You’re a perfectionist

Striving to be perfect—which, let’s face it, is impossible—makes you work much harder and longer than necessary, says Irene S. Levine, PhD, professor of psychiatry at the New York University School of Medicine. “You set goals that are so unrealistic that they are difficult or impossible to achieve, and in the end, there is no sense of self-satisfaction.” Levine recommends setting a time limit for yourself on your projects, and taking care to obey it. In time, you’ll realize that the extra time you were taking wasn’t actually improving your work.

You make mountains out of molehills

If you assume that you’re about to get fired when your boss calls you into an unexpected meeting, or you’re too afraid to ride your bike because you worry you’ll get into an accident, then you’re guilty of “catastrophizing,” or expecting that the worst-case scenario will always occur. This anxiety can paralyze you and make you mentally exhausted, says Levine. When you catch yourself having these thoughts, take a deep breath and ask yourself how likely it is that the worst really will happen. Getting outdoors, meditating, exercising, or sharing your concerns with a friend may help you better cope and become more realistic.

 

You skip breakfast

The food you eat fuels your body, and when you sleep, your body continues using what you consumed at dinner the night before to keep your blood pumping and oxygen flowing. So, when you wake up in the morning, you need to refuel with breakfast. Skip it, and you’ll feel sluggish. “Eating breakfast is like starting a fire in your body by kickstarting your metabolism,” Goodson says. Goodson recommends a breakfast that includes whole grains, lean protein, and healthy fat. Good examples include oatmeal with protein powder and a dab of peanut butter; a smoothie made with fruit, protein powder, low-fat milk, and almond butter; or eggs with two slices of whole-wheat toast and low-fat Greek yogurt.

You live on junk food

Foods loaded with sugar and simple carbs (like the ones you’ll find in a box or at the drive-thru window) rank high on the glycemic index (GI), an indicator of how rapidly carbohydrates increase blood sugar. Constant blood sugar spikes followed by sharp drops cause fatigue over the course of the day, says Goodson. Keep blood sugar steady by having a lean protein along with a whole grain at every meal, says Goodson. Good choices include chicken (baked, not fried) and brown rice, salmon and sweet potato, or salad with chicken and fruit.

You have trouble saying ‘no’

People-pleasing often comes at the expense of your own energy and happiness. To make matters worse, it can make you resentful and angry over time. So whether it’s your kid’s coach asking you to bake cookies for her soccer team or your boss seeing if you can work on a Saturday, you don’t have to say yes. Train yourself to say ‘no’ out loud, suggests Susan Albers, a licensed clinical psychologist with Cleveland Clinic and author of Eat.Q.: Unlock the Weight-Loss Power of Emotional Intelligence. “Try it alone in your car,” she says. “Hearing yourself say the word aloud makes it easier to say it when the next opportunity calls for it.”

You have a messy office

A cluttered desk mentally exhausts you by restricting your ability to focus and limits your brain’s ability to process information, according to a Princeton University study. “At the end of each day, make sure your work and personal items are organized and put away,” suggests Lombardo. “It will help you have a positive start to your day the next morning.” If your office needs major reorganizing, avoid becoming totally overwhelmed by taking it one step at a time: start by tidying what you can see, then move through your desk and cabinets drawer by drawer.

You work through vacation

Checking your email when you should be relaxing by the pool puts you at risk of burnout, says Lombardo. Unplugging and allowing yourself to truly unwind allows your mind and body to rejuvenate and return to the office stronger. “When you truly take breaks, you will be more creative, productive, and effective when you return,” says Lombardo.

You have a glass of wine (or two) before bed

A nightcap sounds like a good way to unwind before falling asleep, but it can easily backfire. Alcohol initially depresses the central nervous system, producing a sedative effect, says Allen Towfigh, MD, medical director of New York Neurology & Sleep Medicine, P.C., in New York City. “But it ultimately sabotages sleep maintenance.” Alcohol creates a rebound effect as it’s metabolized, which creates an abrupt surge in the adrenaline system, he says. This is why you’re more likely to wake up in the middle of the night after you’ve been drinking. Dr. Towfigh recommends stopping all alcohol three to four hours before bedtime.

You check e-mails at bedtime

The glaring light of a tablet, smartphone, or your computer’s backlit screen can throw off your body’s natural circadian rhythm by suppressing melatonin, a hormone that helps regulate sleep and wake cycles, says Dr. Towfigh. Sensitivity to the digital glow of tech toys can vary from person to person, but in general it’s a good idea to avoid all technology for one to two hours before bedtime, he says. Can’t avoid checking your device before your head hits the pillow? Then hold it at least 14 inches away from your face to reduce the risk of sleep interference.

 

You rely on caffeine to get through the day

Starting your morning with a java jolt is no big deal—in fact, studies show that up to three daily cups of coffee is good for you—but using caffeine improperly can seriously disrupt your sleep-wake cycle, says Dr. Towfigh. Caffeine blocks adenosine, the byproduct of active cells that drives you to sleep as it accumulates, he explains. A study published in the Journal of Clinical Sleep Medicine revealed that consuming caffeine even six hours prior to bedtime affects sleep, so cut yourself off by mid-afternoon and watch out for these surprising sources of caffeine.

You stay up late on weekends

Burning the midnight oil on Saturday night and then sleeping in Sunday morning leads to difficulty falling asleep Sunday night—and a sleep-deprived Monday morning, says Dr. Towfigh. Since staying in can cramp your social life, try to wake up close to your normal time the following morning, and then take a power nap in the afternoon. “Napping for 20 minutes or so allows the body to recharge without entering the deeper stages of sleep, which can cause you to wake up more tired,” he says.
