My company invents all kinds of new technology in lots of different areas. And we do that for a couple of reasons. We invent for fun - invention is a lot of fun to do - and we also invent for profit. The two are related because the profit actually takes long enough that if it isn't fun, you wouldn't have the time to do it.

In politics, religion and other areas of culture, people disagree on the worth of competing ideas. There is no equivalent to the scientific method that can determine in a robust way which ideas match the real world, and which ones can be ruled out. So conflicting ideologies persist indefinitely.

People who grow up in a region doubtless have a better cultural awareness of their own cuisine, but it's also true that a lot of locals go to McDonald's, Applebee's and the like.

In the early days of the software industry, people cared about copyright and didn't give a damn about patents - they copied each other willy-nilly.

Why pay a fee for Internet content when a million free sites are just a click away? There's no incentive until people are too addicted to the Net to turn off their computers, yet are bored with what's available.

The scientific method is the ultimate elegant explanation. It is the ultimate foundation for anything worthy of the name "explanation". It makes no sense to talk about explanations without having a process for deciding which are right and which are wrong, and in a broad sense that is what the scientific method is about. All of the other wonderful explanations celebrated here owe their origin and credibility to the process by which they are verified-the scientific method.

I have a very pragmatic approach to diets. Ones you can't stick to don't do you any good. Some people say, 'Just eat half of what's on your plate,' but I can't do that!
