I'm moving all my course materials into quarto.org #Quarto and I kind of love it. #Science #EduSky #AcademicSky

Carl Sagan's The Demon-Haunted World remains eternally relevant: “I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; ... (1/4)

@hankgreen.bsky.social Hey Hank, I just watched your video. Yes, #Artemis II was capturing the reflected #Moon e.g. a "moon glint" in the ocean. Check out the analogous "sun glint" reflections captured by #DSCOVR epic.gsfc.nasa.gov/galleries/20... #Science #NASA #Space

It occurs to me that having everything centralized on the cloud might has some downsides. #EduSky #AcademicSky 🙃

I have a wild idea. Let's take all the private student loan lenders, liquidate them, and jail the C-suites? If I have to read one more desperate post by an 18 year old thinking their life is over because they signed a predatory Sallie Mae loan, I'll scream. #EduSky #AcademicSky #StudentLoans

This is not an expanding supernova, but a "light echo" as light (from V838 Monocerotis) travels through an already present nebula illuminating it over several years. #Science #Space #Astronomy See: en.wikipedia.org/wiki/V838_Mo... This is similar to the #MIT light-camera: youtu.be/EtsXgODHMWk?...

Dead trees remind me of whale-fall, but for forests, as these collapsed titans (pic: fallen White Oak) decompose into soil/humus which sustains future generations of plant and animal life. #Biology #Science #Ecology

What's your favorite particle? I'm particular to the electron. It is a stable, charged fermion with 1/2 spin and a foundational building block to so much of the natural world around us. #Physics #Science

I am finally under dark New Mexico skies. Orion, many other things, and the zodiacal light! 🌌🔭🦛

I always get misty eyed watching the splashdown scene in Apollo 13 and seeing the real thing did the same thing... I just got something in my eye, okay? ❤️ Welcome home #Artemis II! #NASA #Science #Space

Lovely pic of myself and onlookers as we view the Orion Nebula during the #GeorgiaTech April 2 Public Night. We also got a nice pic of the #Moon which is fitting given #NASA #Artemis II's journey. Thanks to GT #Astronomy Club! #Science #Physics #Atlanta Credit: www.flickr.com/photos/gtsci...

Finally, some good #News. "... the pawn immediately in front of a player’s king will be replaced with a sick little hot rod that can move any number of squares horizontally, vertically, or in a circle like it’s doing donuts." theonion.com/internationa...

woke up and still thinking about these

When you get cited on @inspirehep.net and it's an error and you gotta remove it! 😭 (And yes, I put in the correct citation) #Science #Physics #AcademicSky

And here’s the eclipse photo from Artemis II. I am in tears.

😮 Awesome views from Day 2 of #Artemis II this morning. @exploration.esa.int @esaearth.esa.int

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

right now the astronauts are calling houston because the computer on the spaceship is running two instances of microsoft outlook and they can't figure out why. nasa is about to remote into the computer

LIFTOFF!!! #NASA #Space #Artemis

I'm so excited! #NASA #Space #Science Can't wait to have us go back to the Moon. www.youtube.com/live/m3kR2KK...

I showed this graph in class yesterday on how measles cases in the United States plummeted dramatically after the vaccine was licensed in 1963. It’s not subtle and I could not resist observing: “This stunning design in measles cases was not thanks to vitamin A. It was not due to beef tallow.”

It's finally happening!

My god. Have you ever seen close-ups of sea star skin? 🧪🌊🌿

#GardnerDozois 's best short SF of the year collections are always good, but the 1998 one might be the best I've read. My favourite story was a re-read of Ted Chiang's Story of Your Life (later adapted as Arrival) and there are also extremely memorable […] [Original post on fediscience.org]

Cladonia lichen (Cladonia amaurocraea, I think). NWT, Canada. The photo covers about 5cm, left to right. #lichen #fungi #fungifriends

Heng Yang, a M.S. student in Mechanical Engineering and Applied Mechanics at #UPenn came to #Atlanta to visit #GeorgiaTech and his old physics instructor, yours truly, from when we were both at the #UniversityOfArizona. We got coffee, checked out the campus, and visited #Einstein.

I'm a simple man, I see #Science article about neanderthals, I click it. Actually, this is a neat article about mating preferences reveals through #Genetics and #Archeology to acount for the amounts of shared #DNA within X and Y chromosomes.

I was really looking forward to the March launch, totally understand if it needs to be pushed back for safety. #Science #NASA #Space #Artemis

Whale evolution makes me uncomfortable

NASA quietly updated its potential launch windows for its delayed moon mission, apparently now targeting March 6-11

THESE WORDS ARE ACCEPTED. #Cosmere #BrandonSanderson #Mistborn

The Pleiades star cluster (M45) captured over 25 hours. The blue glow is starlight reflecting off interstellar dust. The surrounding brown structures are the Integrated Flux Nebula, incredibly faint clouds lit by the glow of our entire galaxy. #astrophotography #astronomy #space #m45

This is globular cluster NGC 2419, also known as the Intergalactic Wanderer, found in the constellation Lynx, where globular clusters wouldn't normally be found. It orbits the Milky Way every every three billion years and its orbit takes it further than the Magellanic Clouds. #seestar #astronomy

Got married to my now wonderful Wife Sandy!

January 7th is National Old Rock Day! Well here is an old rock! These white circles are cross sections of Archaeocyathids. These were a type of sponge that built reefs during the Early Cambrian. This comes from the the Forteau Formation in southern Labrador, Canada. Over 516 million years old!

The rate of global mean sea level rise has increased from ~2.1 mm/year in 1993 to ~4.5 mm/year in 2023. www.nature.com/articles/s43...

Stuff like this makes me so sad... Libraries are magical places. #Science #Space #NASA

There's a famous Feynman interview where he explains why ice is slippery. It turns out there's more to the story involving shear-stress and slippage of disordered ice layers. Things we experience every day still generate novel thought and research. #Science #Physics journals.aps.org/prl/abstract...
