Quotes from Michio Kaku

La atracción gravitatoria es una ilusión. Por ejemplo, quizá ahora esté sentado en una silla, leyendo este libro. Por lo general, diría que la gravedad tira de usted hacia el asiento, y por eso no sale volando hacia el espacio. Pero Einstein diría que está sentado en la silla porque la Tierra deforma la masa de espacio sobre su cabeza, y esa deformación le empuja hacia el suelo.

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.

Imaginemos también unas hormigas que se mueven sobre una hoja de papel arrugada. No pueden moverse en línea recta. Puede que sientan una fuerza que tira de ellas continuamente, pero nosotros, que miramos las hormigas desde arriba, vemos que no hay ninguna fuerza en absoluto. Esta es la idea que surge de lo que Einstein llamó «relatividad general»: el espacio-tiempo se deforma por masas pesadas, lo que provoca la ilusión de la fuerza gravitatoria.

Number 1: I calls 'em like I see 'em. Number 2: I calls 'em the way they are. Number 3: They ain't nothing till I calls

There are many advantages to space solar energy. It is clean and without waste products. It can generate power twenty-four hours a day, rather than just during daylight hours. (These satellites are almost never in the shadow of the Earth, since their path takes them considerably away from the Earth's orbit.) The solar panels have no moving parts, which vastly reduces breakdowns and repair costs. And best of all, space solar power taps into a limitless supply of free energy from the sun.

El destino no es cuestión de azar; es cuestión de elección. No es algo que hay que esperar; es algo que hay que conseguir. WILLIAM JENNINGS BRYAN

If you take 200 voxels in this area, and look at which of them are active and which are inactive, you can construct a machine-learning device that decodes which number is being held in memory.

Stephen Hawking has proven a general theorem stating that all solutions of Einstein's equations that allow faster-than-light travel must involve negative matter or energy.

Si una idea no parece absurda de entrada, pocas esperanzas hay para ella. ALBERT EINSTEIN

It is, in fact, nothing short of a miracle that the modern methods of instruction have not yet entirely strangled the holy curiosity of inquiry; for this delicate little plant, aside from stimulations, stands mainly in need of freedom.

sin ciencia no hay ciencia ficción.

In other words, positive matter and energy that we see in stars can warp space-time so that it perfectly describes the motion of heavenly bodies. But negative matter and energy warp space-time in bizarre ways, creating an antigravitational force that can stabilize wormholes and prevent them from collapsing and propel warp bubbles to faster-than-light velocities by compressing space-time in front of them.

Safeguards already exist against the release of such a dangerous virus, but steps must be taken to further strengthen them and add new layers of security. In particular, if a new virus suddenly erupts in some distant place on Earth, scientists must strengthen rapid-response teams that can isolate the virus in the wild, sequence its genes, and then quickly prepare a vaccine to prevent its spread.

The 3-D printers of the future might be able to re-create the delicate tissues that constitute functioning organs or the machine parts necessary to make a self-replicating robot.

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.

I have concluded that we are in a world made by rules created by an intelligence. Believe me, everything that we call chance today won't make sense anymore. To me it is clear that we exist in a plan which is governed by rules that were created, shaped by a universal intelligence and not by chance.

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

Music is the voice of God traveling through ten-dimensional hyperspace.

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.

As a practice run before aiming for distant stars, scientists may decide to send nanoships to closer destinations within the solar system. It would take them only five seconds to zip to the moon, about an hour and a half to get to Mars, and a few days to reach Pluto.

Earth changes unimaginably slowly except when it changes suddenly and catastrophically, like right now.

Originally, you were clay. From being mineral, you became vegetable. From vegetable, you became animal, and from animal, man…And you have to go through a hundred different worlds yet. There are a thousand forms of mind. —RUMI
