Michio Kaku Physics Quotes & Sayings

I began to realize something - to understand the future you have to understand physics. Physics of the last century gave us television, radio, microwaves, gave us the Internet, lasers, transistors, computers - all of that from physics. — Michio Kaku

No one knows who wrote the laws of physics or where they come from. Science is based on testable, reproducible evidence, and so far we cannot test the universe before the Big Bang. — Michio Kaku

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that. — Michio Kaku

Years ago, I picked up figure skating. How hard could spins and jumps be, I thought? It's just applied Newtonian physics. After repeatedly falling on my rear end, I realized it was harder than I thought. But it had an upside. That is how I met my wife, who was ice dancing at the Rockefeller Center ice rink. — Michio Kaku

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.) — Michio Kaku

The Europeans and the Americans are not throwing $10 billion down this gigantic tube for nothing. We're exploring the very forefront of physics and cosmology with the Large Hadron Collider because we want to have a window on creation, we want to recreate a tiny piece of Genesis to unlock some of the greatest secrets of the universe. — Michio Kaku

Such thinking is sheer speculation, but the laws of physics allow for the possibility of opening a hole in space by concentrating enough energy at a single point, until we access the space-time foam and wormholes emerge connecting our universe to a baby universe. — Michio Kaku

Think of all the nonsense you had to learn in psychology courses. None of which was testable. None of which was measurable. We had behaviorism, Freudian psychology, all of these theories that you learn in psychology. Totally untestable. Now, we can test it, because physics allows us to calculate energy flows in the brain. — Michio Kaku

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. — Michio Kaku

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.. Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest. — Michio Kaku

In my field, physics, I see that most of us are engage in physics not for the money but for the sheer joy of discovery an innovation. — Michio Kaku

In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time. — Michio Kaku

[On the practical applications of particle physics research with the Large Hadron Collider.]
Sometimes the public says, 'What's 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 ... That's a spin-off. We do this because we want to understand our role and our place in the universe. — Michio Kaku

I vowed to myself that when I grew up and became a theoretical physicist, in addition to doing research, I would write books that I would have liked to have read as a child. So whenever I write, I imagine myself, as a youth, reading my books, being thrilled by the incredible advances being made in physics and science. — Michio Kaku

I would hope that the publicity around the Higgs boson would increase the public awareness of physics and cosmology. — Michio Kaku

We are not at the end but at the beginning of a new physics. But whatever we find, there will always be new horizons continually awaiting us. — Michio Kaku

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace. — Michio Kaku

After that cancellation [of the Superconducting Super Collider in Texas, after $2 billion had been spent on it], we physicists learned that we have to sing for our supper ... The Cold War is over. You can't simply say "Russia!" to Congress, and they whip out their checkbook and say, "How much?" We have to tell the people why this atom-smasher is going to benefit their lives. — Michio Kaku

I have nothing against investment banking, but it's like massaging money rather than creating money. If you're in physics, you create inventions, you create lasers, you create transistors, computers, GPS. — Michio Kaku

(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. — Michio Kaku

In physics, one of the most exciting areas is in nanotech. With computers exhausting the power of silicon, Silicon Valley could become a Rust Belt, unless we can find replacements, such as quantum computers and molecular computers. To be a leader in any field, one has to have a great imagination. Sure, we have to know the basics and fundamentals. But beyond that, we have to let our imagination soar. — Michio Kaku

Eternal life does not violate the laws of physics. After all, we only die because of one word: "error." The longer we live, the more errors there are that are made by our bodies when they read our genes. That means cells get sluggish. The body doesn't function as well as it could, which is why the skin ages. Then organs eventually fail, so that's why we die. — Michio Kaku

What we usually consider as impossible are simply engineering problems ... there's no law of physics preventing them. — Michio Kaku

This was the missing piece in the puzzle. The secret of wood that bound matter together was the Yang-Mills filed, not the geometry of Einstein. It appeared as though this, and not geometry, was the central lesson of physics. — Michio Kaku

Riemann concluded that electricity, magnetism, and gravity are caused by the crumpling of our three-dimensional universe in the unseen fourth dimension. Thus a "force" has no independent life of its own; it is only the apparent effect caused by the distortion of geometry. By introducing the fourth spatial dimension, Riemann accidentally stumbled on what would become one of the dominant themes in modern theoretical physics, that the laws of nature appear simple when expressed in higher-dimensional space. He then set about developing a mathematical language in which this idea could be expressed. — Michio Kaku

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. — Michio Kaku

In sum, the fruition of 50 years of research, and several hundred million dollars in government funds, has given us the following picture of sub-atomic matter. All matter consists of quarks and leptons, which interact by exchanging different types of quanta, described by the Maxwell and Yang-Mills fields. In one sentence, we have captured the essence of the past century of frustrating investigation into the subatomic realm, From this simple picture one can derive, from pure mathematics alone, all the myriad and baffling properties of matter. (Although it all seems so easy now, Nobel laureate Steven Weinberg, one of the creators of the Standard Model, once reflected on how tortuous the 50-year journey to discover the model had been. He wrote, "There's a long tradition of theoretical physics, which by no means affected everyone but certainly affected me, that said the strong interactions [were] too complicated for the human mind.") — Michio Kaku

To understand the precise point when the possible becomes the impossible, you have to appreciate and understand the laws of physics. — Michio Kaku

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future. — Michio Kaku

Hover boards, unfortunately, currently violate the laws of physics. Supermagnets exist, but they have to be cooled to near absolute zero, and they are extremely expensive. So Michael J. Fox's hover boards are not possible until we invent room temperature super conductors. — Michio Kaku

String theory, therefore, is rich enough to explain all the fundamental laws of nature. Starting from a simple theory of a vibrating string, one can extract the theory of Einstein, Kaluza-Klein theory, supergravity, the Standard Model, and even GUT theory. It seems nothing less than a miracle that, starting from some purely geometric arguments from a string, one is able to rederive the entire progress of physics for the past 2 milleninia. All the theories so far discussed in this book are automatically included in string theory. — 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. — Michio Kaku
