No army can withstand the strength of an idea whose time has come. ~Victor Hugo
1846 – The saxophone is patented by Adolphe Sax in Paris, France.
The saxophone was developed in 1841, by Adolphe Sax, a Belgian instrument maker, flautist, and clarinetist working in Paris.[2] While still working at his father’s instrument shop in Brussels, Sax began developing an instrument with the projection of a brass instrument and the agility of a woodwind. He wanted it to overblow at the octave, unlike the clarinet, which rises in pitch by a twelfth when overblown. An instrument that overblew at the octave, would have identical fingering for both registers.
1900 – Wilhelm Cauer, German mathematician is born.
Wilhelm Cauer was a German mathematician and scientist. He is most noted for his work on the analysis and synthesis of electrical filters and his work marked the beginning of the field of network synthesis. Prior to his work, electronic filter design used techniques which accurately predicted filter behaviour only under unrealistic conditions. This required a certain amount of experience on the part of the designer to choose suitable sections to include in the design. Cauer placed the field on a firm mathematical footing, providing tools that could produce exact solutions to a given specification for the design of an electronic filter.
1938 – Pieces of a meteor, estimated to have weighed 450 metric tons when it hit the Earth’s atmosphere and exploded, land near Chicora, Pennsylvania.
On June 24, 1938, a meteorite fell in the vicinity of Chicora. Named the “Chicora Meteor”, the 450+ tonne meteorite exploded approximately 12 miles (19 km) above the Earth’s surface. Only two fragments of the meteorite were found following initial investigations. They had masses of 242g and 61g, and were discovered some miles short of the calculated point of impact of the main mass – which is yet to be found. Two more small fragments were found nearby in 1940.
