What is essential in the life of a man of my kind is what he thinks and how he thinks, and not what he does or suffers.

I think that a particle must have a separate reality independent of the measurements. That is an electron has spin, location and so forth even when it is not being measured. I like to think that the moon is there even if I am not looking at it.

Live life to the fullest. You have to color outside the lines once in a while if you want to make your life a masterpiece. Laugh some every day. Keep growing, keep dreaming, keep following your heart. The important thing is not to stop questioning.

You can't use an old map to explore a new world.

The more I learn, the more I realize I don't know.

Whether or not you can observe a thing depends upon the theory you use. It is the theory which decides what can be observed.

Before God we are all equally wise - and equally foolish.
