Science History

General Science History

In 2014, in the U.S., the manufacture and importing of the common 40-watt and 60-watt general service incandescent lamps was ended under the deadline specified in the Energy Independence and Security Act of 2007. It required better energy efficiency, so that they would be replaced by compact fluorecent, halogen or LED lamps producing more lumens of light per watt of consumption. A modern 43-watt lamp produces the brightness of an old style 60-watt incandescent lamp. Its higher initial purchase price will be more than be paid for in electricity cost savings over a much longer lifetime. Some incandescent types remain exempted, such as appliance, rough service, three-way, candelabra, showcase and other specialty types. The 100-watt incandescent lamp was phased out in 2012, and 75-watt in 2013.

Biology

In 1949, the first photographs of chromosomes and genes were published in Science journal. The article was written by Dr. Daniel Chapin Pease and Dr. Richard Freligh Baker of the School of Medicine, University of Southern California. It described their preliminary investigations made with an electron microscope. Tissue sections as thin as 0.1-μ from the salivary glands of Drosphila melanogaster(fruit fly) were used because of their highly specialized structure with each primordial chromosome reduplicated many times over yielding a giant multiple chromosome made up of 100s or 1,000s of identical units. At moderate magnification by the electron microscope, chromomere granules arranged in bands were readily visible. Scientists did not yet know the structure of DNA, published later by Crick and Watson (25 Apr 1953).

Chemistry

In 1915, Aspirin was made available for the first time in tablet form. The pills were manufactured by Bayer pharmaceuticals in Germany. The medicine had previously been sold in powder form from 1 May 1899. Salicin, the parent compound of the salicylate drug family had been isolated from willow bark in 1829. From 1875, sodium salicylate was used as a commercial pain reliever, despite side effects such as bleeding of the stomach lining. On 10 Aug 1897, a German chemist, Felix Hoffmann, working at the Bayer company, found a suitable, less acidic medication, acetylsalicylic acid. It was marketed by Bayer under the “Aspirin” trademark. It has since become the biggest selling drug in the world as an analgesic (anti-pain), anti-inflammatory, and antipyretic (fever-reducer).

Physics

In 1896, German scientist, Wilhelm Röntgen announced his discovery of X-rays. He sent copies of his manuscript and some of his X-ray photographs to several renowned physicists and friends, including Lord Kelvin in Glasgow and Henri Poincaré in Paris. Four days later, on 5 Jan 1896, Die Presse published the news in a front-page article which described the discovery and suggested new methods of medical diagnoses might be made with this new kind of radiation. One day later, the London Standard cabled the news to other countries around the world about the “a light which for the purpose of photography will penetrate wood, flesh, cloth, and most other organic substances.” It printed the first English-language account the next day.

Earth Science

In 1962, the last signals from the OSCAR 1 satellite were received as its non-rechargeable battery failed. The OSCAR 1 (Orbiting Satellite Carrying Amateur Radio) was the first Amateur Radio satellite, launched on 12 Dec 1961, piggy-backed on a Thor-Agena rocket with the primary purpose of deploying military satellite Discoverer-36. On the way, OSCAR 1 was left in an elliptical orbit just above the Earth’s atmosphere. It was a mere 11-lb, 9×12×6-in, with a radio transmitting HI in Morse code with 140-mW of power on frequency 114.983-Mz. It transmitted for 312 orbits in 22 days, while its signal was picked up by amateurs in 28 nations. Its low orbit shortly decayed and it burned up in the atmosphere on 31 Jan 1962. (It was little more than four years since Russia launched Sputnik on ; 4 Oct 1957.)

January Quote

I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You’re doing things you’ve never done before, and more importantly, you’re doing something. – Neil Gaiman
