This week in scientific history ‘ the electron

This entry was posted in Interesting Phenomena on by .

Whenever you walk through central Cambridge, you will encounter tour groups gathering at key spots throughout the city centre. Science History - On This Day Oldest known insect fossils (390 million yrs) reported in Science; 1993-06-24 Yale computer science professor Dr. David Gelernter loses the sight in one eye, the hearing in one ear, and part of his right hand after receiving a mailbomb from the Unabomber; 2008-09-10 The Large Hadron Collider at CERN, described as the biggest scientific experiment in the history of mankind is powered ... Perhaps the pub where Watson and Crick ‘discovered’ DNA or the Mathematical Bridge, supposedly ‘designed by Isaac Newton’. Another one of these spots is located just outside the SPS Library on Free School Lane: the laboratory where the electron was discovered.’

122 years ago, on the 30th of April 1897, J. J. Thomson announced his discovery of negatively charged constituents of the atom, which we now call electrons. This week in scientific history – the electron | Varsity week in scientific history – the electron. 122 years ago, Thomson discovered the electron in Cambridge’s Cavendish Laboratory, ushering in a new era of big machines, quantum physics and biophysics In the Cavendish Laboratory, then located on Free School Lane, Thompson conducted experiments as Director of the Laboratory. He investigated the conduction of electricity through gases ‘ work for which he would win a Nobel Prize in 1906.

Researchers observe rarest event in history of the universe

Around 1,500 meters deep in the Italian Gran Sasso mountains is the underground laboratory LNGS (Laboratori Nazionali del Gran Sasso), in which scientists search for dark matter particles in a lab sealed off from any radioactivity interference. Today In Sci todayin sci.comToday in Science History Quiz In the margin of most pages, there is a multiple-choice quiz. Each page has a question served randomly from the database. Although there are some easy questions, others are designed to be challenging — to make you think. If you pick the right answer, congratulations. Their tool is the XENON1T detector, the central part of which consists of a cylindrical tank of about one meter in length filled with 3200 kilograms of liquid xenon at a temperature of -95 degrees Celsius.

The observed process is called a double electron capture: The atomic nucleus of Xenon-124 consists of 54 positively charged protons and 70 neutral neutrons, which are surrounded by several atomic shells occupied by negatively charged electrons. Videos for This Week In Scientific History ' The 2:23:07What Can We Learn From History? - This Week in Science Podcast (TWIS)YouTube In double electron capture, two protons in the nucleus simultaneously ‘catch’ two electrons from the innermost atomic shell, transform into two neutrons, and emit two neutrinos. This Week in Scientific History – Marmite as medicine ... Week in Scientific History – Marmite as medicine Love it or hate it, Marmite was the first scientifically proven prenatal supplement, thanks to the work of Newnham scientist Lucy Wills, born 131 years ago As two electrons are then missing in the atomic shell, the other electrons reorganize themselves, with the energy released being carried away by X-rays. However, this is a very rare process which is usually hidden by signals from the omnipresent ‘normal’ radioactivity ‘ in the sealed-off environment of the underground laboratory, however, it has now been possible to observe the process.

What the history of coups in the Middle East tells us about Venezuela

Drew Holland Kinney is a visiting assistant professor of political science at St. John Fisher College.

Though calling the events in Venezuela a coup is contested ‘ the opposition has largely rejected the term, while Maduro’s regime has used it ‘ Guaid’s courting of the military to intervene in the political process and overthrow a state’s executive leadership is a textbook case of civilian coup advocacy.

StoryCorps to visit UO science and culture museum this week

The UO’s Museum of Natural and Cultural History is partnering with the Emmy Award-winning oral history organization StoryCorps to document the experiences of Oregonians involved in social and environmental justice movements.’

The museum’s project, titled Oregon Stories: Speaking of Justice, will bring StoryCorps to campus this week to record conversations between 15 participant pairs who will discuss their work in civil rights, climate stewardship, indigenous cultural justice, educational equity and more.
