Michio Kaku Science Quotations

I am a futurist, projecting trends in science into the next decades and century, but ironically my two daughters - one is a neuroscientist and the other is a pastry chef - tell me that my taste in music is positively prehistoric.

You cannot create new science unless you realize where the old science leaves off and new science begins, and science fiction forces us to confront this.

We have to realize that science is a double-edged sword. One edge of the sword can cut against poverty, illness, disease and give us more democracies, and democracies never war with other democracies, but the other side of the sword could give us nuclear proliferation, biogerms and even forces of darkness.

Leaders in China and India realize that science and technology lead to success and wealth. But many countries in the West graduate students into the unemployment line by teaching skills that were necessary to live in 1950.

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.

For bedtime reading, I usually curl up with a good monograph on quantum physics or string theory, my specialty. But since I was a child, I have been fascinated by science fiction. My all-time favorite is 'The Foundation Trilogy,' by Isaac Asimov.

Having a super-brain does not suddenly make you a dictator of the world. So we don't have to fear the scenarios of science fiction where the Lex Luthors of the world take over. People with exceptional ability, they don't become politicians; they don't become multi-millionaires; some of them just become professors like me, making a measly income.

Anything that promotes a kernel of science, even though it's exaggerated and hyped by Hollywood, I think is a step forward. We in the ivory tower ultimately have to realize that in some sense we have to sing for our supper.

I'm not a science fiction writer, I'm a physicist.

One problem with politics is that it is a zero sum game, i.e. politicians argue how to cut the pie smaller and smaller, by reshuffling pieces of the pie. I think this is destructive. Instead, we should be creating a bigger pie, i.e. funding the science that is the source of all our prosperity. Science is not a zero sum game.

A hundred years ago, Auguste Compte, ... a great philosopher, said that humans will never be able to visit the stars, that we will never know what stars are made out of, that that's the one thing that science will never ever understand, because they're so far away. And then, just a few years later, scientists took starlight, ran it through a prism, looked at the rainbow coming from the starlight, and said: "Hydrogen!" Just a few years after this very rational, very reasonable, very scientific prediction was made, that we'll never know what stars are made of.

I got a four year scholarship to Harvard, and while I was there they wanted to groom me for work in the Star Wars program designing weapons ignited by hydrogen bombs. I didn't want to do that. I thought about how many scientists had died in World War II.

Physicists often quote from T. H. White's epic novel The Once and Future King, where a society of ants declares, "Everything not forbidden is compulsory." In other words, if there isn't a basic principle of physics forbidding time travel, then time travel is necessarily a physical possibility. (The reason for this is the uncertainty principle. Unless something is forbidden, quantum effects and fluctuations will eventually make it possible if we wait long enough. Thus, unless there is a law forbidding it, it will eventually occur.)

You cannot create new science unless you realise where the old science leaves off and new science begins, and science fiction forces us to confront this.

For most of human history, we could only watch, like bystanders, the beautiful dance of Nature. But today, we are on the cusp of an epoch-making transition, from being passive observers of Nature to being active choreographers of Nature. The Age of Discovery in science is coming to a close, opening up an Age of Mastery.
