Quotes from Michio Kaku

Even with a rigorous exercise program, after a year on the space station, the bones and muscles of Russian cosmonauts are so atrophied that they can barely crawl like babies when they first return to Earth.

There are an estimated 100 billion neurons residing inside the skull with an exponential amount of neural connections

So the scale law rules out the familiar idea of worlds-within-worlds found in science fiction, that is, the idea that inside the atom there could be an entire universe, or that our galaxy could be an atom in a much larger universe.

This was the missing piece in the puzzle. The secret of wood that bound matter together was the Yang-Mills filed, not the geometry of Einstein. It appeared as though this, and not geometry, was the central lesson of physics.

Kip Thorne says, "By 2020, physicists will understand the laws of quantum gravity, which will be found to be a variant of string theory.

If we look at the rise of our own civilization over the past 100,000 years, since modern humans emerged in Africa, it can be seen as the story of rising energy consumption.

During the eleven-year sunspot cycle, for example, solar flares can send enormous quantities of deadly plasma racing toward Earth. In the past, this phenomenon has forced the astronauts on the space station to seek special protection against the potentially lethal barrage of subatomic particles.

Either we are alone in the universe, or we are not. Either thought is frightening. –ARTHUR C. CLARKE

Second is N, equal to 1036, which is the strength of the electric force divided by the strength of gravity, which shows how weak gravity is.

I'm as fond of my body as anyone, but if I can be 200 with a body of silicon, I'll take it. —DANIEL HILL, COFOUNDER OF THINKING MACHINES CORP.

Physicists believe that at the instant of the Big Bang, the universe was in perfect symmetry and there was an equal amount of matter and antimatter. If so, the annihilation between the two would have been perfect and complete, and the universe should be made of pure radiation. Yet here we are, made of matter, which should not be around anymore. Our very existence defies modern physics.

If our scientists invent concepts like forces, it is only because they cannot visualize the invisible vibrations that fill the empty space around us. Some scientists sneer at the mention of higher dimensions because they cannot be conveniently measured in the laboratory.

Riemann found that in four spatial dimensions, one needs a collection of ten numbers at each point to describe its properties.

Fourth is Lambda, the cosmological constant, which determines the acceleration of the universe.

We are now entering a new golden age of neuroscience.

Social animals, on the other hand, are more intelligent than those with just a reptilian brain.

Roughly speaking, the greater the value of the metric tensor, the greater the crumpling of the sheet. No mattet how crumpled the sheet of paper, the metric tensor gives us a simple means of measuring its curvature at any point. If we flattened the crumpled sheet completely, then we would retrieve the formula of Pythagoras.

If we can somehow control the probability of certain improbable events, then anything, including faster-than-light travel, and even time travel, is possible. Reaching the distant stars in seconds is highly unlikely, but when one can control quantum probabilities at will, then even the impossible may become commonplace.

This world may be a phantasm and existence may be merely a dream, but this dream or phantasm to me is real enough if using reason well we are never deceived by it.

There was only one period of time when energy on this enormous scale was readily available, and that was at the instant of Creation. In fact, the hyperspace theory cannot be tested by our largest atom smashers because the theory is really a theory of Creation. Only at the instant of the Big Bang do we see the full power of the hyperspace theory coming into play. This raises the exciting possibility that the hyperspace theory may unlock the secret of the origin of the universe.

Imagine fish swimming in a shallow pond, just below the lily pads, thinking that their "universe" is only two-dimensional. Our three-dimensional world may be beyond their ken. But there is a way in which they can detect the presence of the third dimension. If it rains, they can clearly see the shadows of ripples traveling along the surface of the pond. Similarly, we cannot see the fifth dimension, but ripples in the fifth dimension appear to us as light.

Water, for example, is a diamagnet. since all living things are made of water, they can levitate in the presence of a powerful magnetic field. In a magnetic field of about 15 teslas (30,000 times the Earth's field), scientists have levitated small animals, such as frogs. But if room-temperature superconductors become a reality, it should be possible to levitate large nonmagnetic objects as well, via their diamagnetic properties.

Brain Research Through Advancing Innovative Neurotechnologies (or BRAIN) project announced by President Obama, and the Human Brain Project of the European Union, which will potentially allocate billions of dollars to decode the pathways of the brain, all the way down to the neural level.

Cuando estamos sentados en una silla, creemos que la tocamos, pero en realidad estamos suspendidos sobre ella, flotando a menos de un nanometro sobre el asiento
