A boy had reached four without giving up the habit of sucking his thumb, though his mother had tried everything from bribery to reasoning to painting it with lemon juice to discourage the habit. Finally she tried threats, warning her son that, "If you don't stop sucking your thumb, your stomach is going to blow up like a balloon." Later that day, walking in the park, mother and son saw a pregnant woman sitting on a bench. The four-year-old considered her gravely for a minute, then spoke to her saying, "Uh-oh ... I know what you've been doing."

Hans Geiger

Died 24 Sep 1945 at age 62 (born 30 Sep 1882).Hans Wilhelm Geiger was a German physicist who introduced the Geiger counter, the first successful detector of individual alpha particles and other ionizing radiations. After earning his Ph.D. at the University of Erlangen in 1906, he collaborated at the University of Manchester with Ernest Rutherford. He used the first version of his particle counter, and other detectors, in experiments that led to the identification of the alpha particle as the nucleus of the helium atom and to Rutherford's statement (1912) that the nucleus occupies a very small volume in the atom. The Geiger-Müller counter (developed with Walther Müller) had improved durability, performance and sensitivity to detect not only alpha particles but also beta particles (electrons) and ionizing electromagnetic photons. Geiger returned to Germany in 1912 and continued to investigate cosmic rays, artificial radioactivity, and nuclear fission.
