Science quotes

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming. My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all. With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it.
It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics. The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired. Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four. Scientists have become the bearers of the torch of discovery in our quest for knowledge. I believe there are no questions that science can't answer about a physical universe. I have found far greater enthusiasm for science in America than here in Britain. There is more enthusiasm for everything in America. If you believe in science, like I do, you believe that there are certain laws that are always obeyed. It's a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize. Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest. Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time not only affect but are also affected by everything that happens in the universe. God is the name people give to the reason we are here. But I think that reason is the laws of physics rather than someone with whom one can have a personal relationship. An impersonal God. Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Examples include the double helix in biology and the fundamental equations of physics.
Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science. We can allow satellites, planets, suns, universe, nay whole systems of universe, to be governed by laws, but the smallest insect, we wish to be created at once by special act. Freedom of thought is best promoted by the gradual illumination of men’s minds which follows from the advance of science. False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for everyone takes a salutary pleasure in proving their falseness; and when this is done, one path towards error is closed and the road to truth is often at the same time opened. Each living creature must be looked at as a microcosm - a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven. One day, on tearing off some old bark, I saw two rare beetles, and seized one in each hand. Then I saw a third and new kind, which I could not bear to lose, so I popped the one which I held in my right hand into my mouth. Alas! it ejected some intensely acrid fluid, which burnt my tongue so that I was forced to spit the beetle out, which was lost, as was the third one. In conclusion, it appears that nothing can be more improving to a young naturalist, than a journey in distant countries. One hand has surely worked throughout the universe. In the future I see open fields for more important researches. Psychology will be securely based on the foundation already laid by Mr. Herbert Spencer, that of the necessary acquirement of each mental power and capacity by graduation.
String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation. Exploring the unknown requires tolerating uncertainty. Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that's precise, predictive and reliable - a transformation, for those lucky enough to experience it, that is empowering and emotional. Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink. The tantalizing discomfort of perplexity is what inspires otherwise ordinary men and women to extraordinary feats of ingenuity and creativity; nothing quite focuses the mind like dissonant details awaiting harmonious resolution.
In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture. If the theory turns out to be right, that will be tremendously thick and tasty icing on the cake. Over the centuries, monumental upheavals in science have emerged time and again from following the leads set out by mathematics. My view is that science only has something to say about a very particular notion of God, which goes by the name of "god of the gaps". I've seen children's eyes light up when I tell them about black holes and the Big Bang. Physics grapples with the largest questions the universe presents.
"Where did the totality of reality come from?"
"Did time have a beginning?"
The idea that there could be other universes out there is really one that stretches the mind in a great way. The absolute worst thing that you ever can do, in my opinion, in bringing science to the general public, is be condescending or judgmental. It is so opposite to the way science needs to be brought forth. I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for. Science is the greatest of all adventure stories, one that's been unfolding for thousands of years as we have sought to understand ourselves and our surroundings. Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer. My mom says: "Why aren't you a doctor?"
And I'm like, "I am a doctor!"
And she's all, "No, I mean a real doctor."
She reads my books, but she says they give her a headache.
Art makes us human, music makes us human, and I deeply feel that science makes us human. There's no way that scientists can ever rule out religion, or even have anything significant to say about the abstract idea of a divine creator. We are living through a remarkably privileged era, when certain deep truths about the cosmos are still within reach of the human spirit of exploration. I believe we owe our young an education that captures the exhilarating drama of science. I may be a Jewish scientist, but I would be tickled silly if one day I were reincarnated as a Baptist preacher. Science is a self-correcting discipline that can, in subsequent generations, show that previous ideas were not correct. I love it when real science finds a home in a fictional setting, where you take some real core idea of science and weave it through a fictional narrative in order to bring it to life, the way stories can. That's my favorite thing. When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level. Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
