You never know what motivates you.
Well done is better than well said.
Problems are not stop signs, they are guidelines.
Begin to be now what you will be hereafter.
I can, therefore I am.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Only the educated are free.
Be thine own palace, or the world's thy jail.
Wherever you are - be all there.
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.
