This is about Sci-Hub. yeah we get it.. gatekeep knowledge and protect the interests of capital…

Listen, this is serious.

Do not use the website called Sci-Hub!

It lets people access scientific articles for free. This is dangerous. It helps the free flow of knowledge and reduces the competitive edge of all the people who worked really hard to have been born into a wealth.

Like, it’s literally a website where you can type in the DOI of an article and read it, without ever having to pay the publisher who exploited the author.

So, again, do not, under any circumstance, use Sci-Hub. I mean, can you imagine a world where knowledge is free and easily accessible to everyone? Even, y'know, poor people?

Libgen also has many books online, including textbooks, searchable by name, author, and ISBN. Can you imagine textbook companies not getting their hard-earned income from poor college students? Here is the link just so you make sure that you never accidentally stumble across this horrible, unethical website.

Oh, and while we’re talking about books, if you’ve managed to stay clear from Libgen, definitely don’t go to zlibrary, where you can also find a lot of textbooks, but unfortunately they’re completely free.

Reblogging so you know which sites to totally avoid

Stellar collision triggers supernova explosion

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from the Very Large Array Sky Survey (VLASS), a multi-year project using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA).

“Theorists had predicted that this could happen, but this is the first time we’ve actually seen such an event,” said Dillon Dong, a graduate student at Caltech and lead author on a paper reporting the discovery in the journal Science.

The first clue came when the scientists examined images from VLASS, which began observations in 2017, and found an object brightly emitting radio waves but which had not appeared in an earlier VLA sky survey, called Faint Images of the Radio Sky at Twenty centimeters (FIRST).

They made subsequent observations of the object, designated VT 1210+4956, using the VLA and the Keck telescope in Hawaii. They determined that the bright radio emission was coming from the outskirts of a dwarf, star-forming galaxy some 480 million light-years from Earth. They later found that an instrument aboard the International Space Station had detected a burst of X-rays coming from the object in 2014.

The data from all these observations allowed the astronomers to piece together the fascinating history of a centuries-long death dance between two massive stars. Like most stars that are much more massive than our Sun, these two were born as a binary pair, closely orbiting each other. One of them was more massive than the other and evolved through its normal, nuclear fusion-powered lifetime more quickly and exploded as a supernova, leaving behind either a black hole or a superdense neutron star.

The black hole or neutron star’s orbit grew steadily closer to its companion, and about 300 years ago it entered the companion’s atmosphere, starting the death dance. At this point, the interaction began spraying gas away from the companion into space. The ejected gas, spiraling outward, formed an expanding, donut-shaped ring, called a torus, around the pair.

Eventually, the black hole or neutron star made its way inward to the companion star’s core, disrupting the nuclear fusion producing the energy that kept the core from collapsing of its own gravity. As the core collapsed, it briefly formed a disk of material closely orbiting the intruder and propelled a jet of material outward from the disk at speeds approaching that of light, drilling its way through the star.

“That jet is what produced the X-rays seen by the MAXI instrument aboard the International Space Station, and this confirms the date of this event in 2014,” Dong said.

The collapse of the star’s core caused it to explode as a supernova, following its sibling’s earlier explosion.

“The companion star was going to explode eventually, but this merger accelerated the process,” Dong said.

The material ejected by the 2014 supernova explosion moved much faster than the material thrown off earlier from the companion star, and by the time VLASS observed the object, the supernova blast was colliding with that material, causing powerful shocks that produced the bright radio emission seen by the VLA.

“All the pieces of this puzzle fit together to tell this amazing story,” said Gregg Hallinan of Caltech. “The remnant of a star that exploded a long time ago plunged into its companion, causing it, too, to explode,” he added.

The key to the discovery, Hallinan said, was VLASS, which is imaging the entire sky visible at the VLA’s latitude—about 80 percent of the sky—three times over seven years. One of the objectives of doing VLASS that way is to discover transient objects, such as supernova explosions, that emit brightly at radio wavelengths. This supernova, caused by a stellar merger, however, was a surprise.

“Of all the things we thought we would discover with VLASS, this was not one of them,” Hallinan said.

This fake yarn is supposedly better for sheep.

Aimed at people who don’t know where wool comes from, it’s 100% plastic. Yes, plastic.

So any garment you wash will release microfibres into the sea. It’ll never decompose.

You’re supposed to believe that sheep shearing is violent and cruel. There are imbeciles out there that work in an unprofessional manner while shearing, but that’s not the case overall.

Sheep don’t suffer from having their fleece removed.

Left on, the fleece can become a home for fly eggs and the subsequent maggots which can eat the sheep. Chemical treatments are available to prevent that happening. It’s much better for the sheep, the land and the farmer to avoid chemical use.

Don’t be fooled. Wool is a sustainable material, one we should make more and better use of.

Any garment you wash will release microfibres into the sea. It’ll never decompose.

This is very important.

Domesticated sheep must. be. shorn.  They do not shed their coats naturally, and shearing them doesn’t hurt them at all.  A good shearer won’t even nip them once and can shear an entire wiggly adult sheep faster than you can get your hair cut.  Wool is effective at keeping you warm even if it’s wet.  Wool is dramatically more effective at keeping you warm than synthetics in truly extreme environments.  It will keep you nice and toasty and then someday it will biodegrade, just like it’s supposed to.

Wool is humane and sustainable.

This is what a real, qualified OBGYN will tell you about what women feel when they get an abortion

Dr. Willie Parker, who is trained as a gynecologist and OBGYN, is a hero for the pro-choice movement because he’s honest about the undiscussed aspects of getting (or not getting) an abortion. Watch how he gives a consultation.

That last statement about regret is so important, because so many people don’t understand what it is or what causes it. Anti-choicers exploit this by manipulating pregnant people and creating doubt, which only increases the likelihood of regret, no matter what decision the pregnant person makes. You know what is best for you, even if it takes some time to figure it out.

Willie Parker is a HERO among common people! 

Dr. Parker is one of the few things I like about Alabama and we are so fortunate to have him here.

The ordeal of being known wouldn’t be so mortifying if you didn’t want it so very very badly. I overheard someone walking past our apartment at 11pm remarking with surprise on the smell of coffee in the air, and the other neighbor said “oh one of the people in that apartment works night shift.” The strange awareness that other people are also aware in passing of you. I also hope they don’t know this because I wake them up when I leave at midnight. The mortifying ordeal of dropping your keys loudly in the middle of a silent hallway in the middle of the night. Anyway I’m emotional about people.

Me: 🥺 I am known by those around me 🥺

Those around me: how the FUCK does this bitch drop So Many Things at 11:32 pm

I was running late tonight and while rushing at 11:37 pm, I dropped every piece of silverware we own, and as they clattered to the floor, I thought “truly I am Known” while presumably my downstairs neighbors plotted murder
