I conceived of an instrument that would create sound without using any mechanical energy, like the conductor of an orchestra. The orchestra plays mechanically, using mechanical energy; the conductor just moves his hands, and his movements have an eff...
Oh leave the Wise our measures to collate. One thing at least is certain, light has weight. One thing is certain and the rest debate. Light rays, when near the Sun, do not go straight.
I'm interested in finding whether or not there is a really massive, what we like to call 'super massive' black hole at the center of our galaxy. And the reason this is interesting is that it gives us an opportunity to prove whether or not these exoti...
The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And you can do that with the motions of stars. The way the star moves around the center of the galaxy is very much like the way t...
One of the big mysteries about the black hole at the center of the galaxy is, 'Why don't we see emission from matter falling onto the black hole, or, rather, the black hole eating up its surroundings?'
Some people are ok with doing nothing all day after they retire, but then some people if they had nothing to do would go mad and start banging their heads against a wall.
If you share an office next to a guy for twenty years, and you like him and you're friends with him, it's hard to tell him that you think that his whole idea of how the universe works is completely wrong.
Imagine a civilisation that's way in advance of us wants to communicate with us, and assist us in our development. The information we provide to them must reflect our highest aspirations and ideals, and not just be some crazy person's bizarre politic...
It may well be said that the answer to the question: Of what do the cosmic rays in fact consist before they produce their familiar secondary radiation phenomena in the earth's atmosphere? can only be obtained from numerous measurements in the stratos...
In order to make further progress, particularly in the field of cosmic rays, it will be necessary to apply all our resources and apparatus simultaneously and side-by-side; an effort which has not yet been made, or at least, only to a limited extent.
We are at the dawn of a new era, the era of 'molecular biology' as I like to call it, and there is an urgency about the need for more intensive application of physics and chemistry, and specially of structure analysis, that is still not sufficiently ...
Sound is a movement which is handed on from atom to atom in a gas through which the sound is passing, just as a chain of workers pass buckets of water to a fire. The quicker the workers move their hands and arms, the quicker the water moves.
We have experienced an utter explosion in investigative techniques. Walk the streets, look at the cameras! They are now recognising people automatically from photos; we have DNA fingerprinting, infrascan photos that can identify you from the veins in...
By asking a novel question that you don't know the answer to, you discover whether you can formulate a way of finding the answer, and you stretch your own mind, and very often you learn something new.
On another level, I want to mention that I have a strong Jewish identity and - over the years - have been involved in several Jewish projects, such as the establishment of a strong program of Judaic Studies at the University of California in San Dieg...
Coming back to the topic of computer security, the TCP Wrapper is an example of such a safety net. I wrote it when my systems were under attack by someone who appeared to walk through walls.
Generally in life, knowledge is acquired to be used. But school learning more often fits 's apt metaphor: knowledge is treated like money, to be put away in a bank for the future.
Some people's taste is to an educated taste as is the visual impression received by a purblind eye to that of a normal eye. Where a normal eye will see something clearly articulated, a weak eye will see a blurred patch of colour.
The assumption of an absolute determinism is the essential foundation of every scientific enquiry.
The two go hand in hand like a dance: chance flirts with necessity, randomness with determinism. To be sure, it is from this interchange that novelty and creativity arise in Nature, thereby yielding unique forms and novel structures.
At every level in our inventory, nothing seems special about our Earth, our Sun, our Galaxy, our Local Group. Evidently, mediocrity reigns throughout. Such is our niche in the Universe.
