Congo (formerly Zaire) also owns 60% of Coltan, a mineral based on Tantalum and Niobium, much sought after for the manufacture of cell phones. The rapidly increasing demand for Coltan, and the sudden enormous availability of liquidity, is thus mixed with the dirty conflict underway,

Subrahmanyan Chandrasekhar completes a modern exposition of Newton’s Principia Mathematica, in his “Newton’s Principia for the General Reader” (although what he means by the general reader is certainly not what the general reader means…). Euler had done a first complete work in 1735 in “Mechanics”.
1977
Russian chemist Ilya Priggine wins the Nobel Prize for demonstrating that in non-isolated systems operating far from thermodynamic equilibrium (such as living beings), irreversible processes can increase their organization by moving further and further away from thermodynamic equilibrium. The properties of dissipative structures (i.e. irreversible

An article by chemist FJ Donahoe on Polywater (polywater, or water II, or anomalous water) appears in the journal Nature, considering it “the most dangerous polymer on Earth”. The story begins in the quiet Soviet town of Kostroma, where in 1962 Nikolai Fedyakin discovers, or

The journal Chemical Abstract publishes an article on tobacco mosaic virus. It is probably the molecule with the longest name ever pronounced (and some even say it is the longest word): a good 1185 letters. It is C785H1220N212O248S2, better known as: “glutaminylphenylalanylvalylphenylalanylleucylserylseryl valyltryptophylalanylaspartylprolylisoleucylglutamylleucylleucylasparaginylvalylcysteinylthreonylserylseryl leucylglycylasparaginylglutaminylphenylalanylglutaminylthreonylglutaminylglutaminylalanylarginylthreo nylthreonylglutaminylvalylglutaminylglutaminylphenylalanylserylglutaminylvalyltryptophyllysylprolylphenyla

Japan. Doctor Noboru Hagino publishes his findings on the causes of the widespread disease among the families of miners at the Kamioke mine. In 1972, the mining company will compensate the 178 survivors. Cadmium will remain in the collective imagination of the Japanese for generations,
1946
Japan. Doctor Noboru Hagino begins to seriously study the disease of the families of the Kamioke Mine, scientifically, and by superimposing the epidemiological and water map of the area he discovers the cause in the mine. It is Cadmium, which flows downstream in the hydrogeological

Grand Rapids, Michigan, becomes the first city in the world to have its water supply fluoridated. Today, more than half of Americans drink fluoridated water, making the United States one of the most fluoridated populations in the world. The initial test in Grand Rapids with

Auschwitz, now Poland. Primo Levi, a prisoner of the camp, manages to steal some bars of cerium, which he knows well as a chemist, with which he makes lighters that he then sells, exploiting the well-known property of cerium to produce sparks when rubbed. This

Nikola Tesla (Cyrillic: Никола Тесла) (Smiljan, July 10, 1856 – New York, January 7, 1943) was a Serbian physicist, inventor, and engineer who became a naturalized American citizen in 1891. Tesla is best known for his revolutionary work and numerous contributions to the field of
August 1942
Glenn Seaborg isolates Plutonium for the first time. It is also the first time that any artificial element, that is, one that does not exist in nature, is synthesized in its pure form. The first time that the human eye can observe an artificial element.

The German army invades Denmark, where Niel Bohr is staying. He has already donated his gold Nobel medal to charity, but he keeps the two Nobel medals of his German Jewish colleagues Max von Laue (X-ray diffraction) and James Franck (energy quantization). Every gold object

Colorado, United States. Molybdenum is highly sought after by the war industry, especially the German one, since cannons like Big Bertha suffer from deformation due to high temperatures, a defect that disappears if the steel is Molybdenum (which melts at 2600C against 1500C for Iron).

Russo-German Eastern Front. Fritz Haber, the German chemist who synthesized and used Chlorine at Ypres in Belgium, leaves for the Eastern Front to prepare the same deadly weapon of mass destruction. Chlorine tears open the blood vessels of the lungs and the victim drowns in
1915 – 1918
Chlorine, in addition to being used as a chemical weapon (initially only by the Germans), was also used as an additive to drinking water to make it safe for troops. Some say it saved more lives this way than it did as a chemical weapon.
April 22, 1915
Ypres, Belgium. Chlorine synthesized at military level by the German chemist Fritz Haber is used against the Allied troops, especially the French and Algerians. It consists of 5000 cylinders placed along a 7km stretch of front and opened as soon as the wind is favorable
