Physics Quotes

“When World War II came along, which was when I was a teenager, we all expected we would have anthrax bombs and this kind of stuff. We thought it would be a biological war. Fortunately it wasn't and, but it's because the danger is still there and by some miracle we escaped all that, so you never can tell what it going to happen, but biology certainly could be even worse than physics and chemistry.”

“Modern physics has taught us that the nature of any system cannot be discovered by dividing it into its component parts and studying each part by itself... We must keep our attention fixed on the whole and on the interconnection between the parts. The same is true of our intellectual life. It is impossible to make a clear cut between science, religion, and art. The whole is never equal simply to the sum of its various parts.”

“A popular feel for scientific endeavors should, if possible, be restored given the needs of the twenty-first century. This does not mean that every literature major should take a watered-down physics course or that a corporate lawyer should stay abreast of quantum mechanics. Rather, it means that an appreciation for the methods of science is a useful asset for a responsible citizenry. What science teaches us, very significantly, is the correlation between factual evidence and general theories, something well illustrated in Einstein's life.”

“Reality has been around since long before you showed up. Don't go calling it nasty names like 'bizarre' or 'incredible'. The universe was propagating complex amplitudes through configuration space for ten billion years before life ever emerged on Earth. Quantum physics is not 'weird'. You are weird.”

“The question of whether a device will come into being depends upon three things: first, whether there is a practical use for it that warrants its development and manufacturing costs; second, whether the laws of physics applying to the elements available for its design allow the attainment of the needed ranges, sensitivities, or the like; and third, whether the pertinent art of manufacture has advanced sufficiently to allow a useful embodiment to be built successfully.”

“Religion and science, for example, are often though to be opponents, but as I have shown, the insights of ancient religions and of modern science are both needed to reach a full understanding of human nature and the conditions of human satisfaction. The ancients may have known little about biology, chemistry, physics, but many were good psychologists.”

“Food, like anything else, lives in the physical world and obeys the laws of physics. When you whisk together some oil and a little bit of lemon juice - or, in other words, make mayonnaise - you are using the principles of physics and chemistry. Understanding how those principles affect cooking lets you cook better.”

“It's not nuclear physics. You always remember that. But if you write about sports long enough, you're constantly coming back to the point that something buoys people; something makes you feel better for having been there. Something of value is at work there...Something is hallowed here. I think that something is excellence.”

“Invention and entrepreneurship isn't about pure technology. Most people take whatever they see in front of them and relate it to something they understand. For at least ten years after Ford started building cars, people called them horseless carriages. It wasn't obvious to call it a car. They used to call the radio 'the wireless.' Innovation is much more about changing people and their perceptions and their attitudes and their willingness to accept change than it is about physics and engineering.”

“The response to my op-ed by global warming alarmists has been interesting. Former Vice President Al Gore has called me a "denier" and informs us that climate change is "a principle in physics. It's like gravity. It exists." Perhaps he's right. Climate change is like gravity - a naturally occurring phenomenon that existed long before, and will exist long after, any governmental attempts to affect it.”

“Goddard represented a unique combination of visionary dedication and technological brilliance. He studied physics because he needed physics to get to Mars. In reading the notebooks of Robert Goddard, I am struck by how powerful his exploratory and scientific motivations were - and how influental speculative ideas, even erroneous ones, can be on the shaping of the future.”

“Science fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative. If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.”

“The world of physics is essentially the real world construed by mathematical abstractions, and the world of sense is the real world construed by the abstractions which the sense-organs immediately furnish. To suppose that the "material mode" is a primitive and groping attempt at physical conception is a fatal error in epistemology.”

“In science it often happens that scientists say, "You know that's a really good argument; my position is mistaken..."”

“The feeling persists that no one can simultaneously be a respectable writer and understand how a refrigerator works, just as no gentleman wears a brown suit in the city. Colleges may be to blame. English majors are encouraged, I know, to hate chemistry and physics, and to be proud because they are not dull and creepy and humorless and war-oriented like the engineers across the quad. And our most impressive critics have commonly been such English majors, and they are squeamish about technology to this very day. So it is natural for them to despise science fiction.”

“The only difference between causation and the value is that the word "cause" implies absolute certainty whereas the implied meaning of "value" is one of preference. In classical science it was supposed that the world always works in terms of absolute certainty and that "cause" is the more appropriate word to describe it. But in modern quantum physics all that is changed. Particles "prefer" to do what they do. An individual particle is not absolutely committed to one predictable behavior. What appears to be an absolute cause is just a very consistent pattern of preferences.”
