Whatever you think matters - doesn't. Follow this rule, and you will add decades to your life. Rodger Rosenblatt As a well spent day brings happy sleep, so life well used brings happy death.

I am not to blame for putting forward, in the course of my work on science, any general rule derived from a previous conclusion.

Common Sense is that which judges the things given to it by other senses.

There is no result in nature without a cause; understand the cause and you will have no need of the experiment.

A life well used procures a happy death.

Those who are inspired by a model other than Nature, labor in vain.

In time and with water, everything changes.
