Physics Quotes

“What will be required to increase the quality of life and health is a coming together of technology and values, based on a scientific guiding principle that people can agree on. Securing a healthy global future requires this guiding principle to preserve freedom of spirit yet be as provable as the laws of physics. A guiding principle that addresses the meaning of life and is compelling enough to generate social cohesion and behaviors that serve the greater whole. After thirty years of investigation and research, it has become clear to me that the answer lies within the human heart.”

“It is true that physics gives a wonderful training in precise, logical thinking-about physics. It really does depend upon accurate reproducible experiments, and upon framing hypotheses with the greatest possible freedom from dogmatic prejudice. And if these were the really important things in life, physics would be an essential study for everybody.”

“The first thing to realize about physics ... is its extraordinary indirectness.... For physics is not about the real world, it is about "abstractions" from the real world, and this is what makes it so scientific.... Theoretical physics runs merrily along with these unreal abstractions, but its conclusions are checked, at every possible point, by experiments.”

“Natural history is not taught in seminary. This is curious, as most people in pastoral ministry are about 567 times more likely to be asked about cosmology or sub-nuclear physics or human biology or evolution than they are to be asked about irregular Greek verbs or the danger of the patripassionist heresy. If we monotheists are going to go around claiming that our "God made the heaven and the earth," it is not unreasonable to expect us to know something about what that heaven and earth actually are.”

“There are a few societies that show signs of having been very rational about the physics of construction and the physics of real life. Some of the old middle-Eastern societies had downdraft systems over whole cities, and passive, rapid-evaporation ice-making systems. They were rational people using good physical principles to make themselves comfortable without additional sources of energy.”

“Once you've said to yourself, "But I'm not using my physics in my house," or "I'm not using my ecology in my garden, I've never applied it to what I do," it's like something physical moves inside your brain. Suddenly you say, "If I did apply what I know to how I live, that would be miraculous!" Then the whole thing unrolls like one great carpet. Undo one knot, and the whole thing just rolls downhill.”

“You can imagine over very long timescales, perhaps far beyond the multi-decade time scale, we might be able to ask very deep questions about why we feel the way we feel about things, or why we think of ourselves in certain ways - questions that have been in the realm of psychology and philosophy but have been very difficult to get a firm mechanistic laws-of-physics grasp on.”

“One influential philosophical position about the use of probability in science holds that probabilities are objective only if they are based on micro-physics; all other probabilities should be interpreted subjectively, as merely revealing our ignorance about physical details. I have argued against this position, contending that the objectivity of micro-physical probabilities entails the objectivity of macro-probabilities.”

“I studied physics at Princeton when I was a college student, and my initial intention was to major in it but to also be a writer. What I discovered, because it was a very high-powered physics program with its own fusion reactor, was that to keep up with my fellow students in that program I would need to dedicate myself to math and physics all the time and let writing go. And I couldn't let writing go, so I let physics go and became a science fan and a storyteller.”

“The multiverse as a real physical construct within physics overlapping with a more mystical understanding of many possible worlds - the notion of there being a root down at the quantum level between intention and reality, between consciousness and existence - it's not a matter of trying to explain the mystery of magic away with a pat mechanism of a pseudoscience, it's just a matter of trying to ground it in a domain.”

“[Regarding] the soul, I'm a little wary of any discourse on that topic that pretends to have an answer, so I tend to keep my musings to myself. There is interesting, legitimate metaphysical work on the topic going at least as far back as Leibniz and continuing today, following the theme that consciousness, or at least computation, might be at least as fundamental as phenomena such as space, time, energy, and matter, which are the usual subject matter of physics. I follow that sort of thing with interest but with very modest expectations that answers will be arrived at during my lifetime.”

“Evolutionary theory tends to explain quite well in retrospect how various species emerged. It's not very good on prediction. Nevertheless, one cannot say that there isn't a lot of knowledge that's been obtained in this field. In the same way, with these complex physical phenomena between solid state physics, you can say a lot of things without necessarily knowing the next step.”

“I do sense, as compared with let's say the early '50s, there's somewhat more of a careerism. I don't think it's anything special to economics; it's equally true with physics or biology. A graduate education has become a more career-oriented thing, and part of that is because of the need for funding. In fact, that's a much worse problem in the natural sciences than it is in economics. So you can't even do your work in the natural sciences, particularly, and even to some extent in economics, without funding.”

“I love to try to understand first principles and be guided by that. But then, enrich them, because they won't last forever, just like everybody thought Newton had all the answers. And you probably read that, in the last of the 19th century, Harvard and others were discouraging people from going into physics because we have all the answers. And right after that, of course - we have - all this stuff is thrown out the window. And now we have whole new answers.”

“Like most young physicists, when I was a kid enraptured with physics, I thought, "Everything can be explained by the theory of the atom!" But as I've gotten older, and I look at the world, I think there's a lot of ways in which that kind of building up from the smallest building blocks doesn't actually account for the world. As I've gotten older, I've also become sensitive to the ways - to all that is not amenable to explanation. Things that, even if you had an explanation, what good would it be?”

“New laws, new kinds of things can emerge as the universe evolves. The more moving parts you have in something, the more possibilities there are. There's a whole new science now of complexity, and what we see is that complexity requires a very different approach than the kind of bottom-up approach that fundamental physics has always used. We're gonna have to think about the world in a different way if we want to address complex systems.”

“I happen to be a scientist. My background is in nuclear physics. I was a nuclear engineer. But I don't see any incompatibility at all with my religious faith and God the creator of everything and the incompatibility between when the earth was created as specified in the Bible. I don't see any incompatibility there because those that were interpreting God's overall message didn't know anything about modern-day science.”

“If you look at the last 150 years, about every 30 years or so, a new scientific discipline emerges that starts spinning out technologies and capturing people's imaginations. Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution. Today, kids get computers.”

“The idea of suggesting that Hannibal Lecter - in the book, he has a sixth finger and red eyes, and so there is a devilry in Thomas Harris' presentation - so it felt like it was completely honest and appropriate for the character. And we often talk in the writers' room, "Okay, there is the Hannibal as the devil explanation of that plot point, but we also need to ground that in a reality that is answerable to the physics of the storytelling."”

“The thing about physicists is that they tend to think that everything is physics. I don't. That's not what music is to me. You can explain aspects of it in physical terms, including the physics of anatomy: how our bodies move, the torsional moment of inertia, the way you move your body to a beat, the inherent periodicities of the heartbeat, the gait. That's physics, too, I guess - maybe they'd call it biophysics.”

“Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.”

“I don't. We've had three technological revolutions that have changed the course of human history, all driven by physics. In the first, the industrial revolution, physicists developed Newtonian mechanics and thermodynamics, which gave us the steam engine and machine power. The second technological revolution was the electricity revolution. That gave us radio, television, and telecommunications. Then, physicists developed the laser and the transistor.”
