Quotes About Physics

I have suffered from exuberance, from being scattered, a lack of focus, he says. Conflicting enthusiasms caused him to switch scientific fields several times, from high-energy astrophysics to space physics, to particles and fields, and finally to planetary science.

Obsérvese que no estoy afirmando que la física moderna sostenga o demuestre una visión mística del mundo. Lo único que estoy diciendo es que esos físicos eran místicos, no que su disciplina fuera un quehacer místico o espiritual que conduzca a una visión religiosa del mundo.

Si ubicas a tu Dios en la física actual, ese Dios también se tambaleará cuando la física se tambalee. Y eso es precisamente lo que preocupa a estos físicos místicos: no quieren que la física se distorsione, ni que el misticismo se empobrezca con un matrimonio condenado de antemano al fracaso. Gracia y coraje, 27-31

distance, a holistic concept if ever there was one. (Incidentally, there is an excellent book on the new physics—Heinz Pagels's The Cosmic Code21—which is the only book I can unreservedly recommend on the topic.

To exist, the triangle demands three complementary elements: love, power and danger. Mixed incautiously, these elements, like those in physics, are volatile and potentially explosive.

Not believing in force is the same as not believing in gravitation.

This book is about physics and its about physics and its relationship with mathematics and how they seem to be intimately related and to what extent can you explore this relationship and trust it.

Stuart needs "space" and "time," as if this were physics and not a human relationship.

With only the dimmest memories of a high-school course or two in general science, they find themselves confronting dialog which seems largely derived from the frontiers of theoretical physics and a group of characters who might, conceivably, enjoy chatting with Albert Einstein, but certainly no one less advanced. A few pages of all this obscurity and the hapless first reader ... closes the magazine or book ... and abandons the field to the children ...

And so no force however great can stretch a cord however fine into a horizontal line that shall be absolutely straight.

Yes, it is indeed by way of the mathematical forms that the physicist gains knowledge of the external world; Eddington's point, however, is that the forms in question have been artificially imposed: "The mathematics is not there until we put it there." And it is for this reason, and in this sense, that our knowledge of mathematical structures—our knowledge of the physical world!—is said to be subjective.

There is reason to believe that, to some extent at least, the physical universe is actually 'constructed' by the intervention of the physicist, which is the reason John Wheeler refers to it as 'the participatory universe', and why Heisenberg states that physics deals, not with Nature as such, but with 'our relations to Nature'.

What saves the day for physics ... is the fact that the experimentalist does not accept the Cartesian philosophy, which is to say that he treats his apparatus not as a mathematical structure, but as a perceivable object. Even as there are said to be 'no atheists in the trenches', so indeed there are no bifurcationists in the laboratory. All knowledge of the external world begins in the perceptible realm: deny the perceptible object, and nothing external remains.

How could I not have known that there are little things the size of "Planck length" in the universe, which are a millionth of a billionth of a billionth of a centimeter? Imagine if you dropped one in a dark theater how hard it would be to find.

Wavefunction collapse is anything other than "random". If you could really see what was going on, you would see that nothing ever happens randomly, any more than a dice throw produces a genuinely randomly outcome (if you could see what was going on, all the forces in play, you would know exactly what the outcome would be). Sensory ignorance is not ontological uncertainty. Reality knows exactly what it is doing even if you don't!

Physics is a hobby of mine, as much as a person of limited intelligence can understand physics.

Most important part of doing physics is the knowledge of approximation.

Science Fiction is not just about the future of space ships travelling to other planets, it is fiction based on science and I am using science as my basis for my fiction, but it's the science of prehistory - palaeontology and archaeology - rather than astronomy or physics.

They got me reading people like physicist David Bohm with new and passionate interest. He helped me because he turned the essential question upside down. I'd been asking, since everything in the world looks so separate, how can the connections that would seem to be required by this evidence be possible? On the other hand, Bohm was asking, since everything in the world is interconnected, how come everything looks so separate?

Gravity has no pity," her mother said. "Nor physics.

The energy of a body which is due to its position, is called potential energy. The energy of a body which is due to its motion, is called kinetic energy.

Let me here remind you that the essence of dramatic tragedy is not unhappiness. It resides in the solemnity of the remorseless working of things. This inevitableness of destiny can only be illustrated in terms of human life by incidents which in fact involve unhappiness. For it is by them that the futility of escape can be made evident in the drama. This remorseless inevitableness is what pervades scientific thought. The laws of physics are the decrees of fate.

Para que o material se torne visível, a energia precisa ser desacelerada, a fim de que as vibrações aumentem e se cristalizem em alguma coisa tangível.

Liz paced and talked like it was just another test. Another challenge. She was looking at it like an exercise in probability - cause and effect. It's the physics of human nature, and to truly understand it, one has to be objective and cool.
