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

Instructor who gave U of Oklahoma student a zero on anti-trans paper removed from teaching
Graduate assistant Mel Curth found Samantha Fulnecky's paper unscientific and offensive in referring to trans people as "demonic."

A fairwell to #3I/ATLAS, the interstellar visitor, as now it is moving away both from the Sun and Earth. It has dimmed to about mag 12 and has a tail pointing towards the Sun. It will continue getting dimmer and won't be visible in just a few months. #cometWatch #astrophotography

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.

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 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.
