Bret Ernst: Blame America

Everybody likes to blame America for everything. What are we, only 233 years old? These other countries are thousands of years old. Not only did they not get it right, but a lot of times they screw up and ask us for help. Thats like a 90-year-old man asking a two-year-old for advice.

Sir J.J. Thomson

Died 30 Aug 1940 at age 83 (born 18 Dec 1856). Joseph John Thomson was an English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted in 1908. Thomson experimented with currents of electricity inside empty glass tubes, investigating a long-standing puzzle known as “cathode rays.” His experiments prompted him to make a bold proposal: these mysterious rays are streams of particles much smaller than atoms. He called these particles “corpuscles,” and suggested that they might make up all of the matter in atoms. It was startling to imagine particles inside the atom at a time when most people thought that the atom was indivisible, the most fundamental unit of matter.
