Created with Fabric.js 1.4.5 All about Luis Walter Alvarez Luis and his dad invented the bubble chamber. When they made the bubble chamber Luis and Luis won a noble prize.When he was a kid he mad a lot of friends. He wanted to grow up and be inventor. by: James Hall During the 1950's, Alvarez and his associates at the University of California built machines called bubble chambers to detect atomic nuclei and smaller subatomic particles. They also designed computer programs to analyze the results found with such machines. Using these techniques, Alvarez discovered two types of short-lived subatomic particles in 1960. He and other scientists have identified many additional types since Alvarez's most recognized contribution to science may not be his achievements in physics. In the late 1970's, while assisting his son, the geologist Walter Alvarez, the two men uncovered evidence of a large asteroid impact occurring around 65 million years ago. While controversial when first proposed, this asteroid is now widely accepted as the main cause for the disappearance of the dinosaurs Alvarez, Luis Walter." World Book Student. World Book, 2015. Web. 26 Jan. 2015 Bubble chamber was a device that physicists once used extensively to study subatomic particles, units of matter smaller than an atom. Researchers used the chamber mainly to study particles produced in particle accelerators. The bubble chamber has been replaced by various electronic devices The Bubble Chamber A bubble chamber consisted mainly of a cylindrical or boxlike container of liquid. The liquid was heated far above its boiling point, but put under pressure to prevent boiling. When the pressure was rapidly reduced, the liquid boiled at the slightest disturbance Subatomic particles passing through the chamber disturbed the liquid, forming vapor bubbles along their tracks. Scientists used photographs of the tracks to measure the mass, electric charge, and other properties of the particles. The bubbles expanded quickly and had to be photographed within thousandths of a second to get sharp pictures of the tracks.
