overthinking-it-web copy

But Not Simpler has had a great first year (over 1,000,000 hits in eight months!), of course thanks to all my nerdy readers. I did a lot of experimenting here, from controversial pieces about water fluoridation to a piece on taste perception in full Seussian rhyming scheme to a piece proving that a Pacific Rim [...]

Physics in the Mix: Bartending Gets Scientific

Molecular gastronomy—the use of scientific techniques to create exotic cuisine—is becoming a household term. But what about molecular mixology? An article in the December Physics World (free registration required) explores how bartenders are using scientific equipment and techniques to create new cocktails, and how many long-established tricks in the mixologists’ book are firmly rooted in [...]

The Curious Wavefunction

The only two equations that you should know: Part 1

The exponential relationship between equilibrium constant and free energy, the basis of chemistry and life.

“Chemistry”, declared Roger Kornberg in an interview, “is the queen of all sciences. Our best hope of applying physical principles to the world around us is at the level of chemistry. In fact if there is one subject which an ­­­­­educated person should know in the world it is chemistry.” Kornberg won the 2006 Nobel [...]
