We're Having a Nice Time

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.

Like if you want to read basically any physics, math, or CS paper, arXiv.org will have you covered, because everyone uploads their papers there before submitting to a journal (and generally updates it after peer review). I know all of my papers are on there. This is such common practice that journals have it baked into their licensing agreements that authors retain the right to upload their work to these places.

Working at Harvard in the late 1800’s and early 1900’s as a “Computer”, Annie Jump Cannon cataloged stars using their spectra from photographic plates, in an effort to understand the mysteries and peculiarities of stellar spectra.

This was hard, detailed, nuanced work. By 1889, three years into her work, she had classified over 1,000 stars. By 1913, she could classify 200 stars an hour. She could classify three stars a minute, just by sight. Using a magnifying glass, she could classify stars down to 9th magnitude, 16 times fainter than the human eye can see. And she did this all with exceptional accuracy.

Over the course of her career, she personally classified more than 350,000 stars, accounting for a mind-boggling 98% of all contemporary stellar spectra classifications, a feat that wouldn’t be bested until the 1990’s with automated digital sky surveys.

Cannon used these classifications to develop the Harvard spectral classification system (O–B–A–F–G–K–M), organizing stars by surface temperature and physical properties.

It is hard to overstate just how foundational her work was to modern astronomy and astrophysics. Her classifications have enabled more than a century of breakthroughs in stellar structure and evolution, including the understanding of how stars change over time and how temperature, luminosity, and composition are related. The system underpins the Hertzsprung–Russell (HR) diagram, one of the most important tools in astrophysics, and remains embedded in modern research, from stellar population studies to galaxy evolution.

The half-circles are called zaï! They're a traditional farming practice in the Sahel desert, and their introduction + reintroduction can be largely credited to Yacouba Sawadogo, the man linked above! He reintroduced and innovated on the zaï on his own farm in the 1980s, and did extensive outreach (along with scientist Mathieu Ouédraogo) to encourage other farmers to adopt them as well.

He also promoted the use of cordons pierreux, which are basically just lines of rocks to reduce erosion, preserve sediments, and increase water absorption.

for any address to twitter you can replace the “x.com” with “nitter.net” and you will be able to browse as if you have an account. Lifesaver.

Please have a moment of silence for the people who were killed instead of freed when news of emancipation finally reached the furthest corners of the american south.

have another moment for the ledgers, catalogs, and records that were burned and the homes that were destroyed to hide the presence of very much alive and still enslaved people on dozens of plantations and homesteads across the south for decades after emancipation.

and have a third moment for those who were hunted and killed while fleeing the south to find safety across the border, overseas, in the north and to the west.

black people. light a candle, write a note to those who have passed telling them what you have achieved in spite of the racist and intolerant conditions of this world, feel the warmth of the flame under your hand, say a prayer of rememberance if you are religious, place the note under the candle, and then blow it out.

if you have children, sit them down and tell them anything you know about the life of oldest black person you've ever met. it doesn't have to be your own family. tell them what you know about what life was like for us in the days, years, decades after emancipation. if you don't know much, look it up and learn about it together.

This is Juneteenth.

It's probably already been spread around here enough already, but in case anyone's missed it; 7 hours after launch, commander Reid Wiseman, dealing with tech issues, uttered the generational quote "I have two Microsoft Outlooks and neither one of those are working."

After fixing the issues that were afflicting the onboard toilet, mission specialist Christina Koch (who has quickly become my favourite of the four) laughingly said “I’m the space plumber, I’m proud to call myself the space plumber.”

On Easter Sunday, the Artemis II crew hosted a makeshift egg hunt, by hiding packets of dehydrated scrambled eggs around their Orion capsule.

The way the crew always makes sure to make it very clear they're in space when doing interviews. From stuff like Wiseman just hanging out floating sideways on screen or Koch letting her hair loose so it can freely span out flowing around her.

While in transit, the crew decided to record a parody of those bad 80s sitcom intros where everyone turns and smiles at the camera.

When the crew reached the furthest point from Earth in the mission, they jokingly clambored over each other in an effort to get to the far side of the capsule, so that they could individually claim to be the furthest person from earth.

At the same time, on the ISS which was at the time on the other side of earth, the 7 astronauts onboard had a light-hearted race to the far side of the station, making jokes about being the furthest humans from Artemis.

On the way back to earth, NASA actually managed to establish an audio call between the crews of the ISS and Artemis II (where they shared the above info), and Koch called one member of the ISS crew, Jessica Meir, her "astro-sister" as the two of them previously spacewalker together in 2019. Meir then responded I'm so happy that we are back in space together, even if we are a few miles apart" (a few here being 230,000).

In the video the survivor said “Never seek a permanent solution to a temporary problem. And they’re all temporary problems.”

The reblog chain is one of the things that makes Tumblr unlike anywhere else. All the notes on reblogs are attributed to the original post, no matter which branch people actually liked or reblogged. We want to keep encouraging conversations, and give contributors the recognition they deserve. 

Soon, you'll be able to like, reblog, or reply to any part of a reblog chain, and that note will go to that reblog's author. Each reblog will have its own counts, instead of one aggregated number from every version of the post. And yes, you’ll be able to like multiple posts in one chain.

If a reblog doesn't add anything, the love flows up to the last person in the chain who did. Your post doesn't lose notes just because people spread it quietly.

Past notes will stay on the original post — we're only changing what happens from here on out. Retroactively re-attributing all of them would be... a lot.

As this rolls out over the next few days and you explore it, we’ll keep reading your replies and reblogs, so please keep sharing your questions, concerns, and ideas.

Your creativity has always been the heart of Tumblr, whether you’re the original poster or adding something brilliant in the reblogs, and nothing about this change is meant to limit that.
