Schrödinger’s Chef: Quantum superposition and the result-less-ness of unperformed experiments

A pre-dinner conversation leads to a different way of thinking about quantum superposition.  A meal from an idiosyncratic chef is not defined until “the reveal.”  Discussion of this leads to the statement by Asher Peres that “unperformed experiments have no results.”  Discussion of Peres’ statement, then contrasting versions of resultlessness in both macroscopic and quantum realms, leads to classroom discussion.  This, hopefully, creates an easier and deeper understanding of quantum mechanics.

Stamp of the Week #2

Germany issued a pair of stamps that honor two fundamentally huge accomplishments in science in 1994. The Quantum Theory and Ohm’s Law. They were really well designed stamps and very accurate in their science.

The Chemical Laser Show

Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
