NOBEL LAUREATE DONALD GLASER

"I wanted to be sure not to overlook simple experimental possibilities, so I took some bottles of beer, ginger ale, and soda water into my laboratory, warmed them as much as I dared, and opened them with and without a radioactive source nearby."

Remembering physicist and music lover Donald Glaser, born on this day in 1926, who was awarded the physics prize in 1960 for inventing and developing the bubble chamber.

In 1952, Glaser invented the bubble chamber. His invention made it possible to study particles with higher energies compared to what had been possible in the predecessor - the cloud chamber. 

To test the limitations of his new apparatus, Glaser did a beer experiment with his bubble chamber. It went as planned, the only issue being that the Michigan laboratory smelled like a brewery for weeks afterwards.

A artistically-enhanced image that shows the tracks of real particles produced when a neutrino interacted in a liquid mixture of neon and hydrogen inside the Big European Bubble Chamber (BEBC). The tracks become visible when bubbles form along the paths of the particles as a piston expands the liquid. A magnetic field is produced in the detector causing the particles to travel in spirals, allowing charge and momentum to be measured. (text from CERN)
