Quotes by Michio Kaku

“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.”

“There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists. Many of these theories have been killed off only when some decisive experiment exposed their incorrectness.”

“They basically ask their engineers to volunteer some probability figures, then they take the average. This is not science. This is voodoo,”

“Cassini will probably execute a flawless mission around the Earth if it can make the last hurdle through 8,000 pieces of space junk surrounding the Earth,”

“Saturn is not going away, ... Neither are the planets. Whats the rush? Why not delay our space probes a bit, make them smaller and more sophisticated and use solar power?”

“I think he is as close as you are going to get to a living Albert Einstein today.”

“In the history of our intellectual development this will represent the crowning achievement of 2,000 years of investigation into the nature of matter -- space and time.”

“The Air Force is to be applauded for investigating technologies that may have value for national security, ... But wormholes, negative energies, warped space-time, etc., require futuristic technologies centuries to millions of years ahead of ours. The only thing going down the wormhole is taxpayers money.”

Beyond work and love, I would add two other ingredients that give meaning to life. First, to fulfill whatever talents we are born with. However blessed we are by fate with different abilities and strengths, we should try to develop them to the fullest, rather than allow them to atrophy and decay. We all know individuals who did not fulfill the promise they showed in childhood. Many of them became haunted by the image of what they might have become. Instead of blaming fate, I think we should accept ourselves as we are and try to fulfill whatever dreams are within our capability.Second, we should try to leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.

‎By 2100, our destiny is to become like the gods we once worshipped and feared. But our tools will not be magic wands and potions but the science of computers, nanotechnology, artificial intelligence, biotechnology, and most of all, the quantum theory.

[On the practical applications of particle physics research with the Large Hadron Collider.]Sometimes the public says, Whats in it for Numero Uno? Am I going to get better television reception? Am I going to get better Internet reception? Well, in some sense, yeah. ... All the wonders of quantum physics were learned basically from looking at atom-smasher technology. ... But let me let you in on a secret: We physicists are not driven to do this because of better color television. ... Thats a spin-off. We do this because we want to understand our role and our place in the universe.

(The string is extremely tiny, at the Planck length of 10 ^-33 cm, a billion billion times smaller than a proton, so all subatomic particles appear pointlike.)If we were to pluck this string, the vibration would change; the electron might turn into a neutrino. Pluck it again and it might turn into a quark. In fact, if you plucked it hard enough, it could turn into any of the known subatomic particles.Strings can interact by splitting and rejoining, thus creating the interactions we see among electrons and protons in atoms. In this way, through string theory, we can reproduce all the laws of atomic and nuclear physics. The melodies that can be written on strings correspond to the laws of chemistry. The universe can now be viewed as a vast symphony of strings.

The handsome and the beautiful may earn the admiration of society, but all the wondrous inventions of the future are a by-product of the unsung, anonymous scientists.

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.

We should try to leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.

Maybe somewhere telepaths walked the Earth, but I wasnt one of them. In the process, I began to realize that the wondrous exploits of telepaths were probably impossible--at least without outside assistance. But in the years that followed, I also slowly learned another lesson: to fathom the greatest secrets in the universe, one did not need telepathic or superhuman abilities. One just had to have an open, determined, and curious mind. In particular, in order to understand whether the fantastic devices of science fiction are possible, you have to immerse yourself in advanced physics. To understand the precise point when the possible becomes the impossible, you have to appreciate and understand the laws of physics.

It from bit. It’s an unorthodox theory, which starts with the assumption that information is at the root of all existence. When we look at the moon, a galaxy, or an atom, their essence, he claims, is in the information stored within them. But this information sprang into existence when the universe observed itself. He draws a circular diagram, representing the history of the universe. At the beginning of the universe, it sprang into being because it was observed. This means that “it” (matter in the universe) sprang into existence when information (“bit”) of the universe was observed. He calls this the “participatory universe”—the idea that the universe adapts to us in the same way that we adapt to the universe, that our very presence makes the universe possible.

To resolve the discrepancy between waves of probability and our commonsense notion of existence, Bohr and Heisenberg assumed that after a measurement is made by an outside observer, the wave function magically “collapses,” and the electron falls into a definitestate—that is, after looking at the tree, we see that it is truly standing. In other words, the process of observation determines the final state of the electron. Observation is vital to existence.
