A total lunar eclipse – sometimes called a Blood Moon – is set to peak Tuesday, Nov. 8th (tonight), which will run from 5:16 am to 6:41 am ET. It's the last one until 2025. Find out if you’re in an eclipse viewing area or watch it live with NASA Moon experts: go.nasa.gov/3Te4FNt

Super saturn is a saturn like exoplanet with 200 times larger ring 😮 Meet J1407b – an exoplanet 20 times more massive than Saturn. The rings of this Super Saturn span 180 million kilometers wide. That’s larger than the Earth-Sun distance of 150 million kilometers and 200 times bigger than Saturn’s rings! Make no mistake, J1407b is the true Lord of the Rings. Join @ethio_physics

#Newton had published his law of #gravitation in 1687, but he hadn’t made any attempt to determine the constant #G or the mass of Earth. Then in 1798, another English man came into scene and he calculated the #density (and hence the #mass) of the #Earth. That man is our "scientist of the day" today. It's the birthday of #HenryCavendish, the man who devoted his life to science (Scientist of the Day - 10 October) Cavendish was an important experimental and theoretical physicist & chemist. Because of his asocial and secretive behaviour, he often avoided publishing his work, and much of his findings were not told even to his fellow scientists. In the late 19th century, long after his death, #JamesClerkMaxwell looked through Cavendish's papers and found observations and results for which others had been given credit. Some examples of what was included in Cavendish's discoveries or anticipations were:- - Richter's law of reciprocal proportions, - Ohm's law...... T.me/ethio_physics

Continued In the 1960s, #JohnStewartBell developed the mathematical inequality that is named after him. This states that if there are hidden variables, the correlation between the results of a large number of measurements will never exceed a certain value. However, quantum mechanics predicts that a certain type of experiment will violate Bell’s inequality, thus resulting in a stronger correlation than would otherwise be possible. #JohnClauser developed John Bell’s ideas, leading to a practical experiment. When he took the measurements, they supported quantum mechanics by clearly violating a Bell inequality. This means that quantum mechanics cannot be replaced by a theory that uses hidden variables. Some loopholes remained after John Clauser’s experiment. #AlainAspect developed the setup, using it in a way that closed an important loophole. He was able to switch the measurement settings after an entangled pair had left its source, so the setting that existed when they were emitted could not affect the result. Using refined tools and long series of experiments, Anton Zeilinger started to use entangled quantum states. Among other things, his research group has demonstrated a phenomenon called quantum #teleportation, which makes it possible to move a quantum state from one particle to one at a distance.

Yesterday (4th of October) the Royal Swedish Academy of Sciences decided to award the 2022 Nobel Prize in Physics to Alain Aspect, John F. Clauser and Anton Zeilinger “for experiments with entangled #photons, establishing the violation of Bell inequalities and pioneering quantum information science.” Alain Aspect, John Clauser and Anton Zeilinger have each conducted groundbreaking experiments using #entangled quantum states, where two particles behave like a single unit even when they are separated. Their results have cleared the way for new technology based upon quantum information. There is now a large field of research that includes quantum computers, quantum networks and secure quantum encrypted communication. One key factor in this development is how quantum mechanics allows two or more particles to exist in what is called an entangled state. What happens to one of the particles in an entangled pair determines what happens to the other particle, even if they are far apart. Join @ethio_physics
