In our case six researchers are honored by means of one single equation. The problem of baptizing an equation with the name of a scientist is known from street names. ...

This law is known as the second law of thermodynamics, and can be stated in many forms (which may or may not appear at first glance to be equivalent). One form ...

The concept of temperature springs from the observation that a change in physical state (for example, a change of volume) can occur when two objects are in contact with one another, as when a red-hot metal is plunged into water.
