Gravitational waves will bring us exquisitely accurate maps of black holes - maps of their space-time. Those maps will make it crystal clear whether or not what we're dealing with are black holes as described by general relativity.
Our universe - it's three-dimensional, but we can pretend it's two-dimensional so it's like this sheet of paper - and we live in Pasadena over here and London is over there, and it's thousands of miles from Pasadena to London.
Any person, brought into the presence of this fact, stops for a few moments and remains pensive and silent; and then generally leaves, carrying with him forever a sharper, keener sense of our incessant motion through space.
As to the effect of the wave on the air, we will suppose the water to be quite flat and the air motionless, a heavy undulation comes on the scene, it has to pass, so it pushes the air up with its face, letting it fall again as its back glides onwards...
Common sense steps in here and says: Separate the parts you want to be mobile from the parts you want to be inert. You have seen the result, and I know many have the skill to apply it.
Teaching and writing, to me, is really just seduction; you go to where people are and you find something that they're interested in and you try and use that to convince them that they should be interested in what you have to say.
Of course we have Queen Elizabeth as head of state, but in many ways we are a kind of republic. We don't have royals in Australia, so it was kind of unusual to run into those kind of people. But aside from that it was quite ordinary.
If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That's the center of the Milky Way Galaxy and there's a raging black hole at the very center of that constellation that holds the galaxy to...
You have to have a cultural ethic that allows for making mistakes. It cannot be that just because you make mistakes, you're out. You have to make mistakes in order to innovate.
It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.
A young sailor boy came to see me today. It pleases me to have these lads seek me on their return from their first voyage, and tell me how much they have learned about navigation.
Once when I was standing at the base, they started rotating the set and a big, heavy wrench fell down from the 12 o'clock position of the set, and got buried in the ground a few feet from me. I could have been killed!
By the way, it was his simulations that helped out in Jurassic Park - without them, there would have been only a few dinosaurs. Based on his techniques, Industrial Light and Magic could make whole herds of dinosaurs race across the screen.
The simple process of eating and breathing weave all of us together into a vast four-dimensional array. No matter how isolated you may sometimes feel, no matter how lonely, you are never really cut off from the whole.
All matter originates and exists only by virtue of a force... We must assume behind this force the existence of a conscious and intelligent Mind. This Mind is the matrix of all matter.
The stage is like a laboratory where you can run theatrical experiments, imposing interesting conditions on the cast or story and seeing how they pan out. Each new play is like creating a tiny virtual universe enclosed by the confines of the stage.
Whenever I meet in with the words 'Thus it plainly appears', I am sure that hours and perhaps days, of hard study will alone enable me to discover how it plainly appears.
For relaxation, I like to figure skate. Being on the ice and spinning and jumping, I feel very close to nature. In particular, I feel very close to Newton's laws of motion. On the ice, you can experience Newton's laws of motion in their purest, most ...
Rather than bringing me closer to others, the time that I spend online isolates me from the most important people in my life, my family, my friends, my neighbourhood, my community.
I was brought up in a family which valued natural history. Both my parents knew the names of all the British wildflowers, so as we went walking the country, I was constantly being exposed to a natural history sort of knowledge.
My ideas about time all developed from the realization that if nothing were to change we could not say that time passes. Change is primary, time, if it exists at all, is something we deduce from it.
