- The 2019 Papua protests were a series of protests by Papuans in Indonesia that began on 19 August 2019 and mainly took place across Indonesian Papua region in response to the arrests of 43 Papuan students in Surabaya, East Java for alleged disrespect of the Indonesian flag. Many of the protests involved thousands of participants, and some grew from local protests in Surabaya to demanding an independence referendum for the whole region. In several locations, the protests turned into general riots, resulting in the destruction of government buildings in Wamena, Sorong and Jayapura. Clashes between protesters and police resulted in injuries, with over 30 people killed from both the clashes and the rioting.
- Otto Hahn (Wikipedia)
Otto Hahn (pronounced [ˈɔtoː ˈhaːn]; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and discoverer of nuclear fission, the science behind nuclear reactors and nuclear weapons. Hahn and Lise Meitner discovered isotopes of the radioactive elements radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn alone was awarded the 1944 Nobel Prize in Chemistry.
