Betelgeuse has been acting strange lately. Over the past two months it has dimmed considerably. Its luminosity is usually variable, but the amount of dimming is considerable since October, and it being a red giant, could be nearing the end of its life and about to go supernova. https://www.washingtonpost.com/science/2019/12/27/is-betelgeuse-one-skys-brightest-stars-brink-supernova/ https://www.sciencealert.com/betelgeuse-looks-fainter-than-usual-and-we-re-all-hoping-this-star-is-about-to-pop https://www.nationalgeographic.com/science/2019/12/betelgeuse-is-acting-strange-astronomers-are-buzzing-about-supernova/ It is a huge star that, if located in …

Researchers have held individual atoms and released them to interact for the first time. Their secret weapon is a set of three optical tweezer setups to hold atoms in suspension. They made predictions about the few-body problem, but were surprised by their results. https://www.popularmechanics.com/science/amp31026792/scientists-hold-atoms-quantum-physics/?utm_source=quora&utm_medium=referral

The 14th through the 17th is the annual GBBC. This is a great way to join in on a scientific endeavour to monitor the the bird population around the world. Here is the site for the GBBC. As an aside, today was one of my favorite days, it was the first day since last summer that I have heard a Northern Cardinal sing it's territorial song. It was -2F but there was brilliant sun shine, and that was good enough for the Cardinals.😊

Here's an interesting news article on 'Coronavirus Spread', especially if you have ever enjoyed MMORPG's like World of Warcraft (WoW). https://www.abacusnews.com/games/wuhan-coronavirus-prompts-netizens-study-world-warcraft-epidemic/article/3047158 As I started playing in 2008, in 'Burning Crusade', and have had a 'Hunter' character in this game since then, I can provide an expert opinion on the mechanism of these things. Being a highly experienced solo Hunter means that your role is mainly 'ranged attack' but you can also use a hunting 'pet' to assist you by getting it to attack a boss in a dungeon or during a quest. In WoW Dungeons, I hold a title of "Nor…

This is a great article (it could fit in Physics, Computer Science or Mathematics better than here but...) It starts off with some cool animations of how colliding blocks behave, then reveals how the value of pi emerges from that, and then explains how that is equivalent to a quantum search algorithm. It is the closest I have come to understanding how quantum computing actually works! https://www.quantamagazine.org/how-pi-connects-colliding-blocks-to-a-quantum-search-algorithm-20200121/ (I have posted quite a few articles from Quanta Magazine. If you don't already subscribe / follow them then I suggest you do. Excellent source.)

Gravitational waves attributed to the collision of two neutron stars could have been produced by something much stranger.... https://www.scientificamerican.com/article/did-astronomers-just-discover-black-holes-from-the-big-bang/?utm_source=quora&utm_medium=referral Snapshot from the central region of a numerical simulation of two merging neutron stars.

https://phys.org/news/2020-01-particle-chip.html This image, magnified 25,000 times, shows a section of a prototype accelerator-on-a-chip. The segment shown here are one-tenth the width of a human hair. The oddly shaped gray structures are nanometer-sized features carved in to silicon that focus bursts of infrared laser light, shown in yellow and purple, on a flow of electrons through the center channel. As the electrons travel from left to right, the light focused in the channel is carefully synchronized with passing particles to move them forward at greater and greater velocities. By packing 1,000 of these acceleration channels onto an inch-sized chip, Stanfo…

https://amp.businessinsider.com/gravitational-waves-new-class-of-collision-neutron-stars-2020-1?utm_source=quora&utm_medium=referral This article has some really amazing pictures/photos too. This supercomputer simulation shows one of the most violent events in the universe: a pair of neutron stars colliding, merging and forming a black hole. A neutron star is the compressed core left behind when a star born with between eight and 30 times the sun's mass explodes as a supernova. Neutron stars pack about 1.5 times the mass of the sun — equivalent to about half a million Earths — into a ball just 12 miles across. NASA Goddard

There is a wonderful Material fire proof, heat proof material. We can discuss about that material here.

That was paraphrasing the claim in a lay publication that caught my eye. Fortunately, it included a link to the actual article and it is very impressive what they claim. The actual title of the research paper is “Non-contact acquisition of brain function using a time-extracted compact camera” https://www.nature.com/articles/s41598-019-54458-7

This article seemed in line with a couple of interesting threads here https://theconversation.com/shape-of-the-universe-could-it-be-curved-not-flat-126721

This is the first time I have come across this explanation set out in this way. https://www.forbes.com/sites/startswithabang/2019/12/04/this-is-why-scientists-will-never-exactly-solve-general-relativity/#7b33b37734a8 It was not a surprise to me as the intimations have been there in the background up to now... The gist seems to be that, (so far) one can learn all there is to know about the mathematics of GR but its precise application (even a two body problem) is ,not even tantalizingly completely out of bounds. Does it seem a good article to any one else?
