Should #PeerReview in STEM be paid work? I'd think so. I read this blog with fair reasoning. #AcademicSky #Science #EduSky

I also found a journal article which tried this exact thing and found benefits: doi.org/10.1257/jep....
The 450 Movement
I do peer review and I want you to pay me four hundred and fifty dollars. I’ll even say please.

This is why I don't trust charter schools to replace public education. The greed and mismanagement without public oversight is horrifying. #AcademicSky #EduSky #Education
Faith Family Academy is one of eight Texas charter school districts on track to be shut down at the end of the year after receiving an “F” rating.

Board members paid its superintendent a peak annual compensation of $560,000 in recent years.

With @texastribune.org
These Charter Superintendents Are Some of the Highest Paid in Texas. Their Districts Are Among the Lowest Performing.
Three charter school districts in Texas underreported the compensation paid to their top leaders. The same three districts have also had failing or near-failing performance ratings in recent years.

It turns out you can order free hard copies of the NRL Plasma Formulary book from the US Navy. www.nrl.navy.mil/News-Media/P...

The PDF is also freely available.

Making my tax dollars work lol. Though with the shutdown, I don't know if they'll respond. #Physics #Science 🧪⚛️

#TIL the mathematician #Fibonacci (b. 1170) was one of the early promoters of the Indo-Arabic numeral system in Europe in his 13th century book Liber Abaci where he also printed the now famous Fibonacci sequence 1, 2, 3, 5, 8, 13, ... as a solution to the "rabbit problem." #Science #MathSky 🧪🧮

Now here's an example of one of the more useful applications of #AI and #MachineLearning within #Medicine. AI-assisted doctors are significantly better at detecting breast cancers in women. This kind of usage directly saves people's lives. #Science #MedSky 🧪💊

I recently gave a presentation on #AI which covered in-part the dangers of over-reliance in #Medicine. While lots of attention is on #Education, with good reason, even experts are at risk of "deskilling." #AcademicSky #Science #MedSky 🧪💊

I won't stop #Protomen posting until Act III is fully out and dropped. Calling Out is a great song. #Music #RockOpera

Psst. #Physics peeps. If you irradiate lithium-6 with half MeV deuterium ions, you cause #Fusion of the nuclei into two alpha particles aka helium-4. #Science #NuclearPhysics.

Scientists predominantly use X and LinkedIn for professional scientific networking, but with Bluesky and Mastodon in recent years hoping to break through as alternatives.

Happy world squid and cuttlefish day!!

Text your friend a squid fact. Watch a video of a cuttlefish doing something cute.
Doodle a squid and then show it to me.

The world is cruel but squid are good.

Second week of new songs for the #Protomen final album Act III: This City Made Us. I've waited like 16 years for this! No Way Back is an absolute banger. #Music #RockOpera #Rock theprotomen.bandcamp.com/album/act-ii...

Do sub-millisecond pulsars exist?

“NO”

Is that’s a way to start a talk!

This is my favorite #Jazz album and my first #Japanese #CD. Flying Beagle, 1987, is by Himiko Kikuchi. The dog's name is Boogie and is absolutely the reason I originally listened to this.

Hmm. 🤔 Enrollment in bachelor's degrees in #Physics seems to have fallen off a cliff in German universities since the pandemic. Anybody know if this trend has reproduced itself in your country or in another STEM field? #EduSky #AcademicSky #Science 🧪⚛️

TIL that popcorn is an ancient snack with evidence going back to 4,700 BC in Peru via radiocarbon dating. That's potentially older than the potter's wheel! #Science #Archeology #History 🧪
