Never complain and never explain.
Well done is better than well said.
Only the educated are free.
You never know what motivates you.
The dog that trots about finds a bone.
Leap, and the net will appear.
If you can dream it, you can do it.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Quality is not an act, it is a habit.
The scientist is motivated primarily by curiosity and a desire for truth.
Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist's search for truth.
