The Challenger was a terrible tragedy.

I have a great suspicion that the problem is in the management.

Bureaucracy can kill innovation.

The safest thing is to do nothing, but that's not living.

Adventure is worthwhile.

I've always had a fascination with locks and safes.

I once cracked a safe at Princeton just for fun.

The Manhattan Project was the most exciting time of my life.

We were building the atomic bomb to end the war.

The bomb changed the world forever.

I saw the first atomic explosion, and it was beautiful.

The gadget worked.

Now we're all sons of bitches.

The war is over, but the real work begins.

Teaching is a great way to learn.

I hope these lectures will be useful.

Physics is fun.

Caltech is a wonderful place to study physics.

The lectures were for undergraduates, but everyone can learn from them.
