Optical illusion of a woman bent over some papers. Her sunglasses are pushed up and she is wearing a hair band so the top of her head looks exactly like a Muppet face
Sorry I know the world is in a terrible fix but I've been laughing at this for ten minutes now
Multiwavelength Whirlpool Galaxy: Each image shows a narrow band of wavelengths of light and invisible radiation across the electromagnetic spectrum. The wavelength and energy of a photon relates to how fast electrons are accelerated. Low energy radiation comes from cool regions of molecular gas, and high energy radiation comes from hot spots where atoms are fully ionized. The combined images provide insight into the structure, temperature, and chemical composition of the Whirlpool Galaxy. The stars in the infrared image represent most of the mass of the galaxy, excluding dark matter, which can't be seen. The optical image represents a slightly smaller amount of mass and the other three images represent only traces of mass in molecules (radio image) massive hot stars, (ultraviolet image) and hot plasma (x-ray image).
Radio is beyond red
Gamma rays, beyond blue
There are 80 octaves of the electromagnetic spectrum
But only one we can view 🧪
Background music this morning by James Brown, Parliament-Funkadelic, Sly & The Family Stone and other Funk music from the 60s and 70s. I must admit it's hard to stay in my seat (or even stand still) while working! I really miss this vibe.
I remember that fairly well. I was in elementary school and was an early reader - I had an illustrated "comic book" about it. Here's more: en.wikipedia.org/wiki/Interna...
I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.
Stay free
I’m ok. I’m a survivor so this small agitator isn’t going to intimidate me from doing my work.
I don’t let bullies win.
Grateful to my incredible constituents who rallied behind me. Minnesota strong.
20F/-6C, sleet, snow, ice fog, but it was beautiful! 2+ miles in the am and again in the pm. Not.much for most, but lots for central NC!
Thank you, Megan! Inside sign up for the Coffee Session!
And there ya have it…
Officials from top Wall Street firms will be traveling to Venezuela to investigate “investment prospects” of the country. “The trip will feature about 20 officials from the finance, energy and defense sectors.”
Last day, final hike. Aloha, Hawaii. You treated us well. Mahalo!
Happy Christmas to all the stars of my life! May yours be Merry and Bright!
I feel it is important that we honor British film pioneer George Albert Smith. Yes, he helped pioneer editing, closeups, science fiction films, etc. but I think we can all agree that his greatest contribution was as an early trailblazer in the Cat Video genre.
Our colleague Katherine Wright, who began as an editor for PRL and went on to explore her passion as a great writer for
@physicsmagazine.bsky.social, passed away this fall from cancer, far too young. Here is a tribute to her: physics.aps.org/articles/v18...
@scalzi.com So our ride to the airport this morning spoke out of the blue in high terms of the writing of one John Scalzi! Just thought I'd say he's appreciated!
Gneiss statement (groan)! Side note, "gneiss" originally autocorrected to "genius"!
Lol - freezing Dog!
Freezing dog and a temperature of 32F/0C didn't stop me from a 90 minute walk along the Eno River with our dog, Curley. A good pace and appropriate gear made for a comfortable walk. And Nature showed herself with this hawk and its rock domain. We'll go out again this afternoon.
First Secretary of Defense you could defeat by painting a tunnel on the side of a boulder.
Half Marathon completed despite a complete lack of training Teaching physics and coaching cross country were priorities. Being 74 might have had an impact as well.
Nice evening on the deck, fire pit, planked salman, rice, and sauteed vegetables. Calm reflective evening.

Ada Lovelace Day has begun! As midnight arrives on Kiritimati Island in the middle of the Pacific Ocean, our global celebration of women in science, technology, engineering and maths begins! Join us in celebrating by posting about your fave women in STEM #ALD25!

A “catastrophic failure called sunset”🤔 Astronomers would like a word.
They are lovely. We have two of those my mother made nearly fifty years ago. They are next to two paintings done by my father-in-law. Both are gone but their memories persist through their art. Of course there are other memories as well but those done by their hand are special. And so will be yours.
NASA's Lunar Reconnaissance Orbiter has imaged the crash site of ispace's Mission 2 "RESILIENCE", which made a hard landing on the Moon on 5 June 2025.
It's the dark smudge in the very centre of this image, surrounded by a lighter halo, the result of disturbing the uppermost lunar regolith.
