Two 7.5 digit meters to do a high school lemon battery experiment. If it's worth doing, it's worth over doing.

@sciguyspace.bsky.social do you find it odd that Amazon Kuiper KA-01 still has not been scheduled? There might be a story here. Rocket issue? Payload issue? FAA issues because of musk interference?

Unpopular opinion: If someone offered me the chance of a lifetime, to experience something exceptionally few people will ever experience in their lifetime, I'd f'ing do it. Would I post about it on social media? Yeah I would. Am I a bad person? Maybe. See also: Airplane and Helicopter Pilot

When you create a simulator for your machine, you can generate a shitload of automated test cases to make sure the machine does the right thing in various circumstances.

Five years ago today, most historical UK monthly rainfall observations were not available to scientists. But the 66,000 pieces of paper containing the data had been scanned. With covid lockdown approaching we saw an opportunity to transcribe the data. #RainfallRescue began... 🧵

Thanks. Everyone seems mad at me again (as usual...from both sides). We did a "soft release" on this CS show (first in 3 years)so that those who never unsubscribed from the feed and REALLY wanted this got first crack at it. They got that. So here's the link: dts.podtrac.com/redirect.mp3...

Phyllopteryx taeniolatus, the common seadragon, is native to Australia coastal waters. They rely on really effective camouflage to blend into seaweed, have a long jawless snout that lets them slurp up invertebrate prey. A truly impressive snoot. (📷: Katieleeosborne)

I feel like the president does not understand tit-for-tat or how it has become the standard for diplomacy.

I don't follow more people because I am but a single human who wants his bluesky feed to be a curated stream of delightful reads, not an unmanageable firehose of posts he will never get to. If you followed me on the unspoken condition of a reciprocal follow, it's okay to unfollow me now.

Reminder that I don't argue with fascists here, I block them. I also block people who whine that I won't listen to the fascists. Who gets to determine when someone is acting like a fascist and/or fascist book licker? Why, I do. If you don't like it, try not being a fascist and/or a boot licker.

The first person to document that light had a speed is, arguably, Danish astronomer Ole Rømer, in 1676. Our story starts with the challenge of calculating longitude. In 1598 Philip III of Spain offered a large prize for any method to accurately determine east/west coordinates for a ship at sea.

It would be helpful if more people understood renewable energy is actually an extremely disruptive technology and the reason monied interests are trying to make folks hate it is that they are the ones which will be disrupted.

(1/3) It needs repeating: in 1994, Ukraine was persuaded to give up its nuclear weapons to Russia in return for the US, the UK, and Russia guaranteeing Ukraine’s sovereignty, security, and territorial integrity.

Okay, nerds, buckle in! It's time for some SCIENCE. Back in the late 1960s, a scientist got some government funding from the National Science Foundation (NSF) and the Atomic Energy Commission to look for interesting bacteria living in extreme environments. 1/x

Nobody's asking elected Dems to legislate right now. Constituents want them to act like politicians who are as alarmed by what's happening as they are, which is especially rich after an election season that spent a lot of time painting the opposition as threats to democracy (which they are!).
