Quotes About Science

Los dos mayores misterios de la naturaleza son la mente y el universo.

Algún día, los científicos podrían construir una «internet de la mente», o brain-net, en la que los pensamientos y las emociones se enviarían electrónicamente de un lugar a otro del mundo

It is estimated that, if the ice caps of Mars were completely melted, there would be enough liquid water to fill a planetary ocean fifteen to thirty feet deep.

One of the most beautiful photographs of a galactic black hole is the one taken by the Hubble space telescope of the galaxy NGC 4261.

sin ciencia no hay ciencia ficción.

A pesar de lo descabellado de la teoría de cuerdas, uno de los aspectos que la ha mantenido con vida es que combina satisfactoriamente los dos grandes pilares de la física, la relatividad general y la teoría cuántica, ofreciéndonos una teoría finita de la gravitación cuántica. De ahí viene todo el entusiasmo.

Llegarán a superarnos los ordenadores en inteligencia? Ciertamente no hay nada en las leyes de la física que lo impida.

In the beginning God said, the four-dimensional divergence of an antisymmetric, second rank tensor equals zero, and there was light, and it was good. And on the seventh day he rested.

It was Johannes Kepler who first noticed the effect when he realized that, contrary to expectations, comet tails always point away from the sun. Kepler correctly surmised that pressure from sunlight creates these tails by blowing dust and ice crystals in comets away from the sun.

Goddard murió en 1945 y no vivió lo suficiente para ver la disculpa escrita por la dirección del The New York Times después de que el Apolo llegara a la Luna en 1969: «Ha quedado definitivamente demostrado —escribieron— que un cohete puede operar en el vacío y no solo en una atmósfera. El Times lamenta el error».

Graphene consists of a single molecular layer of carbon atoms tightly bonded to form an ultra-thin, ultra-durable sheet. It is almost transparent and weighs practically nothing, yet is the toughest material known to science—

To do this, we will have to exploit the fourth wave of science, which consists of artificial intelligence, nanotechnology, and biotechnology.

Back in the 1980s, there was enormous enthusiasm about gene therapy, i.e., repairing broken genes. There are at least 10,000 known genetic diseases afflicting the human race. There was a belief that science would enable us to rewrite the code of life, correcting the mistakes of Mother Nature. There was even talk that gene therapy might be able to enhance the human race as well, improving our health and intelligence at the genetic level.

In many ways, we actually know more about the surface of Mars than the surface of the Earth. About three-quarters of the Earth is covered by the oceans, while Mars has no oceans.

Stapledon gives us another possibility as he writes, "Some of these pre-utopian worlds, not malignant but incapable of further advance, were left in peace and preserved, as we preserve wild animals in national parks, for scientific interest.")

I've started to interact with geologists around the world, scientists who've dedicated their lives to studying glaciers and ice fields, and it's tough for all of us to realize that we're studying a system in decline, the demise of the cryosphere, that frozen part of the world.

Titan could become an important gas station in space.

It is easy to calculate how much sunlight falls on a square foot of land on Earth. Multiplying this by the surface area of the Earth illuminated by the sun and one immediately calculates the approximate energy of an average Type I civilization. (We find that a Type I civilization harnesses the power of 7 x 1017 watts

Many people ask the simple question, "Why can't we cure the common cold?" Actually, we can. But since there are over 300 rhinoviruses that can cause colds, and since they constantly mutate, it makes no sense to develop 300 vaccines to hit this moving target. We simply live with it.

And there is no such thing as absolute zero, the temperature at which all motion stops. (Even as we approach it, atoms continue to move slightly, which is called the zero-point energy.)

This is not just an academic exercise, since one day we may have to alter and enhance our bodies using cybernetics or even change our genetic makeup in order to survive in hostile exoplanetary environments. Transhumanism, instead of being a branch of science fiction or a fringe movement, may become an essential part of our very existence.

According to him, microscopic robots, or nanobots, will circulate in our blood and "destroy pathogens, correct DNA errors, eliminate toxins, and perform many other tasks to enhance our physical well-being.

Once a small planet is discovered, astronomers try to determine which category it belongs to. This is like biologists trying to classify a new animal as either being a mammal or reptile.
