The biggest changes are the kids and the resources they have. They use the scientific method better than I've ever seen it used before.

But the reason I call myself by my childhood name is to remind myself that a scientist must also be absolutely like a child. If he sees a thing, he must say that he sees it, whether it was what he thought he was going to see or not. See first, think later, then test. But always see first. Otherwise you will only see what you were expecting.

I don't believe we've seen anything like this before.

My father-in-law had an anvil and he gave it to me. I noticed it had a name on it. I thought that was interesting, so I tried to get all the different kinds I could.

That's probably the Cadillac of American anvils.

Everything must be taken into account. If the fact will not fit the theory---let the theory go.
