Professor and physicist. Black holes, quantum gravity, cosmology. Rocky Top. Tar Heel. Reposts are spooky action at a distance. These are my views, not my employer's. Just terrible at this.
Dr. Samuel P. Massie, chemist who worked on liquid uranium compounds for the Manhattan Project, helped develop compounds to fight numerous diseases, and was the first Black professor at the US Naval Academy, was born #OTD in 1919. 🧪

Halide served me well for a long time, but now it’s practically unusable. Shooting on an *iPhone 14 Pro* and responsiveness and performance are both so poor, I wonder why I bother.
Color variations in this WMAP image show small departures – about .00002 K – from the average CMB temperature of 2.726 K.
Tiny local variations in density caused CMB photons to lose a bit more or less energy as they climbed out of slightly more or less dense regions. 🔭 🧪

The Wilkinson Microwave Anisotropy Probe (WMAP) launched from Kennedy Spaceflight Center #OTD in 2001.
Three months later it would reach the L2 Lagrange point and begin to assemble an exquisitely detailed map of the cosmic microwave background. 🧪 🔭

(I’m traveling, so I’m off by a day. Pretend this is yesterday.)
Physicist Maria Goeppert Mayer was born #OTD in 1906. She developed the nuclear shell model of the nucleus, for which she was awarded the 1963 Nobel Prize in Physics. 🧪 👩🔬

Yes, things seem bad now. But in 150 billion years, most of the Universe currently visible to us will have slipped behind a cosmic horizon. Our little archipelago of gravitationally bound galaxies will find itself huddled and alone, dead stars bathed in dim thermal static. Oed' und leer das Meer.

NFL just lost their antitrust trial. The jury ordered them to pay $4 billion in damages to the consumer class, which is tripled to $12 billion.
One of the jurors is an astrophysicist. They requested a bunch of data that wasn’t in evidence. Judge suggested they were devising their own damages model!

And tell your friends to buy it, too.
Then tell them to pick up this beautiful, poignant novel about motherhood, friendship, and how some young women were stripped of agency during the Baby Scoop era in the US.

A conversation on our Discord has prompted me to say again: remember, y'all, what really sells books is not the author talking about their work, but *readers* talking about it. Word of mouth drives far more sales than advertising or any other engine. So if you loved a book, tell your friends!

Hello new friends!
Have a look at Messier 13. Visible to the naked eye, if the sky is dark enough.
Edmund Halley spotted it in 1714 and wrote “This is but a little Patch, but it shews it self to the naked Eye, when the Sky is serene and the Moon absent.” Which, same.

Showing this to the kid, it's worth sharing again for everyone to have a look.
Most of the things you see in this JWST image are distant galaxies – only the objects with diffraction spikes are stars! This deep field image was one of the first JWST releases.
