Quotes by Physicists

Aging is basically the build-up of error: error at the genetic level, error at the cellular level. Cells normally repair themselves; that's why you heal when you get a cut. But even the mechanism of repair eventually falls apart. Michio Kaku
You Genetic Heal Build-Up Repair Falls Error Normally Get Cells Cellular Apart Cut Themselves Aging Mechanism Even Eventually Why Level Basically
When I was 16 years old, I assembled a 2.3 million electron volt beta particle accelerator. I went to Westinghouse, I got 400 pounds of translator steel, 22 miles of copper wire, and I assembled a 6-kilowatt, 2.3 million electron accelerator in the garage. Michio Kaku
Old Beta Steel Pounds Wire Particle Accelerator Got Years Translator Miles Electron Garage Million Copper
Nations that use commodity capitalism as a stepping-stone to a mixed economy based on commodity/intellectual capitalism will most likely become rich. Michio Kaku
Capitalism Will Become Rich Economy Most Likely Mixed Commodity Nations Use Based
I believe that science is the engine of prosperity, that if you look around at the wealth of civilization today, it's the wealth that comes from science. Michio Kaku
Today You Science Wealth Prosperity Believe Civilization Look Around Engine
In science, nothing is ever 100% proven. Michio Kaku
Science Nothing Proven Ever
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
Good Science Physics Reading String String Theory Favorite Trilogy All-Time Since Isaac Science Fiction Quantum Quantum Physics Bedtime Been Up Child Curl Fiction Asimov Theory Fascinated Foundation Specialty
You see, I'm also a futurist. I dream about the world 50, 100, maybe even 1,000 years in the future. But I also realize I'm probably not going to see it. However, I wouldn't mind having at least a copy of myself see the future, maybe 50, 100, 1,000 years into the future. It would be a fantastic ride. Michio Kaku
Future Myself You Ride World Mind Dream Would Would-Be See About Having Also Least However Years Going Maybe Fantastic Realize Even Copy
The Internet frees people to realize they don't have to live like slaves. Michio Kaku
People Internet Live Like Realize Slaves
Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible. Michio Kaku
Life Mother Impossible Space Will Our Circular Possible Outer Outer Space Cross Collision Preventing Highly Most Making Jupiter Any Often Orbit Planet Planets Means Fling Star Travels
Of course the word chaos is used in rather a vague sense by a lot of writers, but in physics it means a particular phenomenon, namely that in a nonlinear system the outcome is often indefinitely, arbitrarily sensitive to tiny changes in the initial condition. Murray Gell-Mann
Physics Word Sense Changes Chaos Indefinitely System Outcome Rather Writers Particular Namely Course Nonlinear Condition Lot Often Tiny Sensitive Means Used Initial Phenomenon Vague
Our planet doesn't seem to be the result of anything very special. Murray Gell-Mann
Result Our Our Planet Seem Very Anything Planet Special
How wonderful that we have met with a paradox. Now we have some hope of making progress. Niels Bohr
Hope Wonderful Progress Met Paradox Some How Making Now
I can only speak for particle physics. But it has become obvious that on the experimental side, there has been a huge evolution in the number of people who have to collaborate because of the gigantic size of the instruments used, but also because of the enormous task that is data analysis. Peter Higgs
People Physics Speak Become Enormous Analysis Side Collaborate Evolution Has-Been Gigantic Data Only Particle Also Obvious Instruments Because Been Huge Task Size Experimental Used Who Number
I'm a great admirer of 'The Simpsons.' It's very surprising because it's backed by a right-wing television company in the U.S., and quite often it's poking fun at the people who would be its audience. Peter Higgs
Great People Backed Right-Wing Television Would Would-Be Admirer Simpsons Poking Because Audience Surprising Very Quite Often The Simpsons Who Fun Company
It's nice to be right sometimes. Peter Higgs
Sometimes Nice Right
Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen. Richard P. Feynman
You Experience Clouds Seen Nothing Waves Scale About Direct Direct Experience Small Small Scale Weights Particles Like Springs Balls Very Behave Any Anything Ever Things
There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics. Richard P. Feynman
Physics Made Atoms Nothing Living Laws Point Point Of View Understood According Cannot View Acting Things
Perhaps one day we will have machines that can cope with approximate task descriptions, but in the meantime, we have to be very prissy about how we tell computers to do things. Richard P. Feynman
Day Will Approximate Machines One Day Tell About Computers Perhaps How Very Task Meantime Descriptions Cope Things
From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work - not the places where they do work! That is the way in which we discover new rules. Richard P. Feynman
Work Physics Way Rules Point Point Of View New Most Course Discover New Places Where Which Places Interesting View Basic Phenomena
First figure out why you want the students to learn the subject and what you want them to know, and the method will result more or less by common sense. Richard P. Feynman
You Result Will First Sense Out More More Or Less Students Know Learn Method Subject Common Want Common Sense Them Figure Less Why
There is always another way to say the same thing that doesn't look at all like the way you said it before. I don't know what the reason for this is. I think it is somehow a representation of the simplicity of nature. Richard P. Feynman
Nature You Simplicity Before Same Thing Think Way Say Somehow Like Know Look Another Another Way Said Always Same Representation Reason Thing
I want to marry Arline because I love her - which means I want to take care of her. That is all there is to it. I want to take care of her. I am anxious for the responsibilities and uncertainties of taking care of the girl I love. Richard P. Feynman
Love Care Girl Responsibilities Marry Uncertainties Take Take Care Taking Because Am Anxious Want Which Means Her
Before I was born, my father told my mother, 'If it's a boy, he's going to be a scientist.' Richard P. Feynman
Mother Father Before Born He Boy Scientist Going
When I was about thirteen, the library was going to get 'Calculus for the Practical Man.' By this time I knew, from reading the encyclopedia, that calculus was an important and interesting subject, and I ought to learn it. Richard P. Feynman
Time Library Man Important Reading Ought About Knew Calculus Practical Learn Subject Encyclopedia Get Going Interesting Thirteen
Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea. Richard P. Feynman
Beautiful Achievement Physics Space Single Relations Resulted Exciting Idea Greatest Said Geometry Einstein Which Theoretical Theory Connecting Gravitational Phenomena
If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly. Richard P. Feynman
Future Time Will Predict State Say We Cannot Exactly Atom Only Emission Excited Any Going Probability Cannot Certain
