• For all the sublimity of art, physics, music, mathematics, and other manifestations of human genius, everything depends on the mundane, frustrating, often debased vocation known as politics (and its most exacting subspecialty - statecraft). Because if we don't get politics right, everything else risks extinction.

• I suppose my interest in looking for life elsewhere in the universe really dates back to my teens. What teenager doesn't look up at the sky at night and think am I alone in the universe? Well most people get over it, but I never did and though I made a career more in physics and cosmology than astrobiology I've always had a soft spot for the subject of life because it does seem so mysterious.

• Similarly for marking exercises, quantitative exercises, maybe not so much in mathematics, but certainly problem sets in physics, chemistry, and engineering and things like that where answers and methods are clear cut, absolutely. I would like to see that done online.

• We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.

• I think my dad [ Stephen Hawking] would have been pleased if I had turned out a scientist because he truly believes that is the most interesting career open to anyone. But he also believes that you have to follow your own path in life and so he certainly wasn't going to push me toward theoretical physics when it didn't look like I was going in that direction naturally.

• When you advance a frontier, you're doing something that no one has done before. Every time that happens, you have to innovate. You have to think in new ways that hadn't been thought before. You have to invent a new piece of hardware, a new concept, a new law of physics, a new material, a new construction material to enable you to accomplish what it is that you chose to reach for by dreaming about tomorrow.

• Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the time. It's whole universes coming into and out of existence.

• In terms of the most astonishing fact about which we know nothing, there is dark matter and dark energy. We don't know what either of them is. Everything we know and love about the universe and all the laws of physics as they apply, apply to four percent of the universe. That's stunning.

• Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.

• On the contrary, it's because somebody knows something about it that we can't talk about physics . It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance gold transfers we can't talk about, because those are understood so it's the subject that nobody knows anything about that we can all talk about!

• Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.

• It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].

• When physics, chemistry, biology, medicine, contribute to the detection of concrete human woes and to the development of plans for remedying them and relieving the human estate, they become moral; they become part of the apparatus of moral inquiry or science? When the consciousness of science is fully impregnated with the consciousness of human value, the greatest dualism which now weighs humanity down, the split between the material, the mechanical and the scientific and the moral and ideal will be destroyed.

• If time is treated in modern physics as a dimension on a par with the dimensions of space, why should we a priori exclude the possibility that we are pulled as well as pushed along its axis? The future has, after all, as much or as little reality as the past, and there is nothing logically inconceivable in introducing, as a working hypothesis, an element of finality, supplementary to the element of causality, into our equations. It betrays a great lack of imagination to believe that the concept of "purpose" must necessarily be associated with some anthropomorphic deity.

• The most powerful influence exercised by the Arabs on general natural physics was that directed to the advances of chemistry ; a science for which this race created a new era.(...) Besides making laudatory mention of that which we owe to the natural science of the Arabs in both the terrestrial and celestial spheres, we must likewise allude to their contributions in separate paths of intellectual development to the general mass of mathematical science.

• Physics is to be regarded not so much as the study of something a priori given, but rather as the development of methods of ordering and surveying human experience. In this respect our task must be to account for such experience in a manner independent of individual subjective judgement and therefore objective in the sense that it can be unambiguously communicated in ordinary human language.

• Mathematics is not something that you find lying around in your back yard. It's produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle physics and astrophysics, areas of fundamental science that are very, very far removed from everyday affairs.
