“Physics is a wrong tool to describe living systems.”

born: 21 september 1926, Cleveland, Ohio, U.S.

died: 28 february 2013, Berkeley, California, U.S.

American physicist and recipient of the 1960 Nobel Prize for Physics for his invention  and construction of the bubble chamber, a analysis instrument utilized in high-energy physics laboratories to observe the behaviour of subatomic particles.Glaser performed analysis with Nobelist Carl Anderson, who was using cloud chambers to study cosmic rays. Glaser, recognizing that cloud chambers had various limitations, created a bubble chamber to study in regards to the pathways of subatomic particles. Because of the relatively high density of the bubble-chamber liquid , collisions producing uncommon reactions were more frequent and had been observable in finer detail. New collisions can be recorded each few seconds when the chamber was uncovered to bursts of high-velocity particles from particle accelerators. In consequence, physicists were ready to discover the existence of a host of new particles, particularly quarks. On the age of 34, Glaser was some of the youngest scientists ever to be awarded a Nobel Prize.
