Simeon Denis Poisson quotes

Life is good for only two things, discovering mathematics and teaching mathematics.
 Simeon Denis Poisson 
Life is only good for two things, doing mathematics and teaching it.
 Simeon Denis Poisson

There are men that teach best by not teaching at all.

Everybody is now so busy teaching that nobody has any time to learn.

If nobody said anything unless he knew what he was talking about, a ghastly hush would descend upon the earth.

Science is the outcome of being prepared to live without certainty and therefore a mark of maturity. It embraces doubt and loose ends.

Where lies the line between sorcery and science? It is only a matter of terminology, my friend.

I believe that words are strong, that they can overwhelm what we fear when fear seems more awful than life is good.

When life is good and we have no problems, we can almost let ourselves believe we have no need for God. But in my experience, sometimes the richest blessings come through pain and hard things.

My version, of course, is not this flagwaving, let's all get on the Jesus train and ride out of hell. I'm not that kind of guy. It's an embrace that life is good, worth living and yeah, it's not easy, but there are more pluses than minuses.

You are what you eat." Nothing else. Never. If you are nourished with cow's milk and later with herbs, you'll become someone whose whole life is good only for being exploited by others.

To live is to change, and to be perfect is to have changed often.
