This strip came out in 1995. What would Calvin’s dad have to say about technology in 2022? 😬🫠 #CalvinandHobbes

we need BBC One's The Repair Shop, but for lab equipment.

JAY: What 'ave we got here mate?
ME: It's a Pfeiffer Hi-Cube turbomolecular pumping station. I'd love to see it get past 30,000 rpm again, like it did for my dear departed colleague <sniff>
NARRATOR: Forrrtunately Angus Cruickshank, one of Kurrt Leskerrr's top field technicians, is standing by
JAY: Wotcher, Angus?
ANGUS: Och now here's a dear little turbo. Bearings, do we think?

Mercator size vs. true country size

Today’s #APOD is a #video about the power of ten, made in the late 70’s.

I won’t share it here because I believe there are better and more recent videos to explain the HUGE scale difference between the very very small, sub-atomic and the very very large, astronomical scales.

I like the one below, made by Harry Evett. On that video you can see the difference between the smallest scale we know, until the largest one.

"Become an astronomer," they said. "It'll be fun," they said.

Chile has some of the best skies for nighttime observing, thanks to its many high and dry desert mountains. The lack of moisture means most nights of the year are cloud-free 😎🌌

These photos were taken during a winter storm on Cerro Pachón in June 2022.

Emacs' repeat-mode https://karthinks.com/software/it-bears-repeating/ was introduced with Emacs 28 and is one of the minor modes that make living in Emacs so much easier. #emacs

#MaunaLoa Telescope update!

The ATLAS units have been shut down finally and people have left. The picture below was taken by one of those folks.

The power is out, it's possible the power lines were taken out by lava. It will be a while before people can go back and check on material.

Until then ATLAS still has 3 units across the globe to detect any potentially dangerous asteroids that could hit earth!

So we stay safe from the sky whilst we admire the power of mother Earth 🙏 🌋

55 years ago #today Jocelyn Bell discovered the first known pulsar -- a star the size of a city, spinning once a second, whipping up intense radio signals that sounded like the beep-beep-beep of an alien signal.
