Classical Physics Quotes

#1. Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.

Carl Friedrich Von Weizsacker

#2. The law of right-left symmetry was used in classical physics but was not of any great practical importance there. One reason for this derives from the fact that right-left symmetry is a discrete symmetry, unlike rotational symmetry, which is continuous.

Chen-Ning Yang

#3. Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics - this is the reason why quantum mechanics seems so foreign to our everyday existence.

Alain Aspect

#4. A consistent pursuit of classical physics forces a transformation in the very heart of that physics.

Werner Heisenberg

#5. Given that the 'common sense' of many contemporary philosophers is shaped and supplemented by ideas from classical physics, the locus of most metaphysical discussions is an image of the world that sits unhappily between the manifest image and an out of date scientific image.11

James Ladyman

#6. [About describing atomic models in the language of classical physics:]
We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

Niels Bohr

#7. Turbulence is the most important unsolved problem of classical physics.

Richard P. Feynman

#8. What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.

Wolfgang Pauli

#9. When somebody goes outside the cultural norms, the culture has to protect itself.

Robert M. Pirsig

#10. ...quantum problems unseat many classical ideas about matter, causality, and change that biologists use, and that disruption in turn entails radical revisions to the ideas about the mechanism in evolution, in ways we don't yet acknowledge.

Ashish Dalela

#11. But Rawkus is integral to what I do, because the cats who started Rawkus are the first ones who really saw my vision, and gave me a platform to get it out there, so I'm definitely totally grateful for that.

Talib Kweli

#12. Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong.

Neil Turok

#13. He was forever inventing a new way of doing an old thing and doing it better and quicker, but he never in his whole life had any talent for making money.

John Steinbeck

#14. The advantage of a quantum walk over a classical random walk can be appreciated by returning to our slow-moving drunk and imagining that the bar he leaves has sprung a leak and that water is pouring out of its door.

Jim Al-Khalili

#15. When I was young I used to have this thing where I wanted to see everything I used to think 'How can I die without seeing every inch of this world?'

Leonardo DiCaprio

#16. Quality and service are important, if you want to make a sale. If you want to keep a customer for life, keep your promises.

Heidi

#17. Einstein does not remain attached to the classical principles, and when presented with a problem in physics he quickly envisages all of its possibilities. This leads immediately in his mind to the prediction of new phenomena which may one day be verified by experiment.

Henri Poincare
