Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy.

The light interacts with the cavity and makes an arbitrary number of bounces before leaking out. This emergent light is traditionally treated as heat in quantum simulations. However, it can still be ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

Unscrambling eggs is still impossible, an example of entropy in action. But boiling eggs is no longer the one-way process it used to be. Scientists in California and Australia have figured out how to ...

Let ent denote topological entropy, and let $C'r(S^1, S^1)$ denote the space of continuous functions of the circle to itself having $r$ continuous derivatives with ...

In the current debate over "Intelligent Design," the strongest argument offered by opponents of design is this: we have scientific explanations for most everything else in Nature, what is special ...
