Jake paralysis outbreak occurs in United States.
 
(Jake paralysis was neuropathy caused by drinking a Jamaican ginger extract (commonly called “jake”) diluted with an industrial chemical known as triorthocresyl phosphate (TCP or TOCP).
 
Jake had been legally sold for medicinal purposes since the Civil War. Because it was about 70% alcohol, it was widely used during prohibition in the U.S. (1920-1933) as a means of legally consuming alcohol. (Contrary to common belief, the consumption of alcohol was legal during prohibition; it was the production, distribution and sale of alcoholic beverages that was prohibited.)
 
However, in 1930, the manufacturer of jake decided to water down the product with the cheap, tasteless, water-soluble TCP. The highly toxic result (one of the uses of TCP was as a pesticide) was that an estimated 50,000 people in the US were temporarily or permanently paralyzed.
 
The paralysis was called commonly jake foot or jake leg because the neuropathy caused victims to walk in a distinctive manner. The muscles that permit a person to raise the toes were paralyzed, so victims had to raise their feet high so as not to drag their feet. As they stepped, their toes would come down first followed by a jarring “thud” sound caused by the drop of the heels.))
 
Subrahmanyan Chandrasekhar provides a theory for the existence of white dwarf stars and determines that a white dwarf can exist only if its mass is less than 1.44 times that of the Sun. This comes to be known as Chandrasekhar's limit. Arthur Eddington had earlier predicted white dwarf stars, but will disagree with Chandrasekhar on the details in a notable scientific argument of the 1930s, with Chandrasekhar generally seen as the winner.
 
Swiss-American astronomer Robert Julius Trumpler shows the existence of diffuse interstellar dust by studying its dimming effect on star clusters. As one consequence of the dust, the size of the Milky Way Galaxy is about three-fifths as big as previous estimates, which assumed that observed dimming was caused by distance.
 
Bernard Ferdinand Lyot builds the coronagraph, a special telescope in which a baffle stops the light from the solar disk and allows observation of the corona.
 
Bruno Benedetto Rossi, Italian-American physicist points out that cosmic rays should be deflected by Earth's magnetic field -- to the east if positive and to the west if negative. Studies show the deflection to the east, establishing that most cosmic rays are positive.

Russian-German optician Bernhard Voldemar Schmidt invents the corrector for a combined camera and telescope, producing a device that allows very wide-angle views with little distortion. The Schmidt telescope comes to dominate astronomy because it is free from coma, an aberration.

As I Lay Dying. Faulkner's most experimentally daring novel, written over a six-week period when Faulkner was working the night shift at a powerhouse, is a multivocal stream-of-consciousness account of the poor white Bundren family's journey to bury their mother, Addie, in her native town, Jefferson, Mississippi. The book combines horror, comedy, and a profound meditation on the nature of being.
