Quotes About Science

he was able to estimate the size of the nucleus of the atom. It was one hundred thousand times smaller than the atom itself.

Science and technology are the engines of prosperity. Of course, one is free to ignore science and technology, but only at your peril. The world does not stand still because you are reading a religious text. If you do not master the latest in science and technology, then your competitors will.

In other words, the process of observation determines the final state of the electron.

Since Einstein derived his famous equation, literally millions of experiments have confirmed his revolutionary ideas.

At rest, we know that its circumference is equal to p times the diameter. Once the merry-go-round is set into motion, however, the outer rim travels faster than the interior and hence, according to relativity, should shrink more than the interior, distorting the shape of the merry-go-round. This means that the circumference has shrunk and is now less than p times the diameter; that is, the surface is no longer flat. Space is curved.

Each of the genes of the human body is spelled out explicitly in this dictionary, but what each does is still largely a mystery.

In other words, the reason why the string theory cannot be solved is that twenty-first mathematics has not yet been discovered.

Atomic machines are actually found in nature. Cells can swim freely in water because they can wiggle tiny hairs. But when one analyzes the joint between the hair and the cell, one sees that it is actually an atomic machine that allows the hair to move in all directions. So one key to developing nanotechnology is to copy nature, which mastered the art of atomic machines billions of years ago.)

The problem is that while twenty-first-century physics fell accidentally into the twentieth century, twenty-first-century mathematics hasn't been invented yet. It seems that we may have to wait for twenty-first-century mathematics before we can make any progress, or the current generation of physicists must invent twenty-first-century mathematics on their own.

How wonderful that we have met with paradox. Now we have some hope of making progress. —NIELS BOHR

As the great biologist Thomas H. Huxley said in 1863, "The question of all questions for humanity, the problem which lies behind all others and is more interesting than any of them, is that of the determination of man's place in Nature and his relation to the Cosmos.

A quantum theory of gravity that unites it with the other forces is the Holy Grail of physics.

Since the speed of light squared (c^2) is an astronomically large number, a small amount of matter can release a vast amount of energy. Locked within the smallest particles of matter is a storehouse of energy, more than 1 million times the energy released in a chemical explosion. Matter, in some sense, can be seen as an almost inexhaustible storehouse of energy; that is, matter is condensed energy.

Eternal Sunshine of the Spotless Mind

When bathed in telomerase, skin cells divide indefinitely, far beyond the Hayflick limit. ..... But it should be pointed out that telomerase has to be regulated very carefully, because cancer cells are also immortal and they use telomerase to attain that immortality.

in string theory, the dimensionality of space-time is fixed at ten dimensions.

Feynman once wrote, quantum mechanics "describes nature as absurd from the point of view of common sense. And it fully agrees with experiment. So I hope you can accept nature as She is–absurd.

Like the invention of the telescope, the introduction of MRI machines and a variety of advanced brain scans

To make Harry Potter invisible, one would have to liquefy him, boil him to create steam, crystallize him, heat him again, and the cool him, all of which would be quite difficult to accomplish, even for a wizard

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.

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.

There is an old saying: If appearance and essence were the same thing, there would be no need for science

The fruit fly has roughly 150,000 neurons in the brain.
