Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of survival. The dinosaurs never knew what hit them.
We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbil...
We're presently in the midst of a third intellectual revolution. The first came with Newton: the planets obey physical laws. The second came with Darwin: biology obeys genetic laws. In today’s third revolution, were coming to realize that even mind...
If our local, observable universe is embedded in a larger structure, a multiverse, then there's other places in this larger structure that have denizens in them that call their local environs the universe. And conditions in those other places could b...
Rather than opera, football is more like ballet or a chess game. You can really see it in a team like Arsenal, especially when Dennis Bergkamp was playing. He seemed to be able to read the game like a chessboard and knew where a player would be sever...
The wonderful thing about maths is it's a totally logical subject, and a pathway has been marked out. I think a lot of these things can be crystallised in something quite essential, that people can get. If I can't explain it, I realise that's probabl...
... informed ignorance provides the natural state of mind for research scientists at the ever-shifting frontiers of knowledge. People who believe themselves ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is ...
The way Moore's Law occurs in computing is really unprecedented in other walks of life. If the Boeing 747 obeyed Moore's Law, it would travel a million miles an hour, it would be shrunken down in size, and a trip to New York would cost about five dol...
If you depend on a secret for your security, what do you do when the secret is discovered? If it is easy to change, like a cryptographic key, you do so. If it's hard to change, like a cryptographic system or an operating system, you're stuck. You wil...
When I was 8 or 9, I started using bulletin board systems, which was the precursor to the Internet, where you'd dial into... a shared system and shared computers. I've had an email address since the late '80s, when I was 8 or 9 years old, and then I ...
I use many different gadgets connected with computers; I use PCs, laptops and a Palm Pilot. I also use the Internet to visit websites, especially within Polish-language Internet. I usually go to political discussion groups and sites - of course, as I...
As a child, I did what any normal kid who grew up without any electricity would do - I spent countless hours working on a computer wired to my parents' car battery... and learned how to code. This natural passion for computers lead me into the Intern...
The root cause of the looming energy problem - and the key to easing environmental, economic and religious tensions while improving public health - is to address the unending, and unequal, growth of the human population. And the one proven way to red...
I don't want to give advice to people about their religious beliefs, but I do think that it's not smart to bet against the power of science to figure out the natural world. It used to be, a thousand years ago, that if you wanted to explain why the mo...
I had a great deal of confidence when I graduated from Berkeley. I had almost none when I was at Princeton. After a while, when people tell you you can't do something because you're a woman, you begin to believe maybe they're right.
The energy necessary to create a wormhole or to wrap time into nuts is incredible. It's not for us. It's maybe for our descendants who have mastered the energy of this technology. So if one day, somebody knocks on your door and claims to be your grea...
When I was about nine years old, I announced to my mother that I was going to cook Thanksgiving dinner. And I went to the library and got this whole pile of books. I'd love to say it all turned out great. It didn't. But, sort of, from that point on, ...
You see, I'm also a futurist. I dream about the world 50, 100, maybe even 1,000 years in the future. But I also realize I'm probably not going to see it. However, I wouldn't mind having at least a copy of myself see the future, maybe 50, 100, 1,000 y...
I'm not saying that atheists can't act morally or have moral knowledge. But when I ascribe virtue to an atheist, it's as a theist who sees the atheist as conforming to objective moral values. The atheist, by contrast, has no such basis for morality. ...
I liked Edinburgh as a university in a way that I'd never enjoyed King's College London. I realised after I came to Edinburgh that perhaps it was a mistake to have gone to a college which was bang in the centre of a vast city. It had a bad effect on ...
The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy ...
