I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.

If we teach only the findings and products of science - no matter how useful and even inspiring they may be - without communicating its critical method, how can the average person possibly distinguish science from pseudoscience?

When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.

We are like butterflies who flutter for a day and think it is forever.

There is a report that says that kids who watch violent TV programs tend to be more violent when they grow up. But did the TV cause the violence, or do violent children preferentially enjoy watching violent programs?

What an astonishing thing a book is.

There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
