NASA's Office of Commercial Exploration has been concerned about protecting the landing zones where humans first walked on the Moon, and one of my colleagues, ecologist Margaret Race, has been part of their deliberations.
The longtime standard for American TV was 525 lines from top to bottom of the image. As a practical matter, that was roughly equivalent to 350 thousand pixels - pretty crude, given that photos made with your iPhone boast five million pixels.
The most important precedents deal with the whole idea of symbolic programming - the notion of setting up symbolic expressions that can represent anything one wants, and then having functions that operate on both their structure and content.
With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.
I'm committed to seeing this project done. To see if within this decade we can finally hold in our hands the rule for our universe, and know where our universe lies in the space of all possible universes.
I'm not a fan of giving a website a simple number like an IQ rating because like people they can vary in all kinds of different ways. So I'd be interested in different organisations labelling websites in different ways.
Imagine that everything you are typing is being read by the person you are applying to for your first job. Imagine that it's all going to be seen by your parents and your grandparents and your grandchildren as well.
On the web the thinking of cults can spread very rapidly and suddenly a cult which was 12 people who had some deep personal issues suddenly find a formula which is very believable.
The physicist had no time to waste on a symbol; his concern was with what the symbol denoted. To the typesetter the symbol and its denotation were bound in an organic unity. There was a meaning to the symbol itself which only the typesetter could app...
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.
I do theoretical particle physics. We're trying to understand the most basic structure of matter. And the way you do that is you have to look at really small distances. And to get to small distances, you need high energies.
There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe...
It's not completely obvious what gravity is, fundamentally, or what dimensions are, fundamentally. One of these days we'll understand better what we mean, what is the fundamental thing that's given us space in the first place and dimensions of space ...
An almost indispensable skill for any creative person is the ability to pose the right questions. Creative people identify promising, exciting, and, most important, accessible routes to progress - and eventually formulate the questions correctly.
I often feel a discomfort, a kind of embarrassment, when I explain elementary-particle physics to laypeople. It all seems so arbitrary - the ridiculous collection of fundamental particles, the lack of pattern to their masses.
Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there's no coherent final consensus on why there is space.
Certein bodies... become luminous when heated. Their luminosity disappears after some time, but the capacity of becoming luminous afresh through heat is restored to them by the action of a spark, and also by the action of radium.
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.
I think also of my colleagues in elementary particle theory in many lands, and feel that in some measure I am here as a representative of our small, informal, international fraternity.
