When Star Trek the Movie came out back in '79 it had a much criticized sequence of shots where the camera basically drools over the Enterprise (1701A) in dry dock. But I was the target audience.
I hope we get a Bird of Prey next. We probably also have enough […]

We got to the final listed track, track 15 "The Fate of Thomas Light" and it's the saddest bit of music I've listened to in awhile. Everybody in the Bandcamp livestream was devastated. This can't be the end of Act III. #Protomen #Music #RockOpera

Comet 240P/NEAT has now a small fragment (B) that is bright enough to be seen with modest telescopes. The nucleus shines at about mag 12 while B is two magnitudes fainter. #cometWatch #astrophotography

I love #Quasars! This is 3C 273, brightest in the sky, by #HST #Hubble, 2.5 billion light-years away. The bottom blocks out the supermassive #BlackHole showing more detail. The "L" is a jet, possibly from a disrupted dwarf galaxy. #Science #Astronomy #Space.

This week's Act III #Protomen is "The Dream." Amazing call back to Act III and it's cool to hear Emily again in the story, even only as a memory. #Music #ConceptAlbum #RockOpera.
We're getting to the endgame now.

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.

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.

#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 🧪🧮

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.
