I’ve always thought this! All those words are carefully defined before that scene so that Bigwig’s defiance needs no translation. Huge payoff.

Hey folks, my friend Toya's account has been labeled as spam and she's trying to get it reinstated. Meanwhile she still needs help with daycare while she looks for a new job. If you can chip in, please do! 🙏🏻

Ohio State just advised all staff and students not to attend the SACNAS (Society for the advancement of Chicanos and Native Americans in Science) annual meeting of 6000+ scientists -- which is in Columbus, OH this year! -- saying it may be exclusionary, even though it is open to all.

🔭 Heads up, #Denver! Our next FREE star party is happening this Saturday! Come on over to look through our telescopes, tour the historic building, and meet our amazing @uofdenver.bsky.social physics students! ✨

Bonus: Saturn is back! 🪐

Interior of the University of Denver's historic Chamberlin Observatory. A long white telescope stands on a black pillar in the center of a round room with brick red walls and a curved gray ceiling. The telescope is pointing out an opening in the dome toward a dark blue sky. People are standing around the room waiting their turn to climb a ladder at right that allows them to look through the telescope.

Disney reverses course on Kimmel. Lessons:

-Trump's anti-Constitutional stances, anti-1A in this case, are unpopular
-Popular resistance via expression and spending choices can have an impact
-Many corporate leaders are weak, amoral people who'll bow to threats unless they face countervailing ones

Breaking: Jimmy Kimmel to return Tuesday.

The Fall/Autumnal Equinox is TODAY at 2:19 PM EDT. That's the time at which our Sun is directly over the Earth's equator, signaling the start of Northern Hemisphere astronomical fall. The Earth’s northern hemisphere will continue to tilt further from the sun through the Winter Solstice on Dec 21.
Graphic showing Earth during the June solstice and September equinox. At the equinox, sunlight is evenly distributed along the equator. Text notes Fall Equinox 2025 occurs Sept 22 at 2:19 pm EDT.

The entire point of writing is discovery. You don’t know what you don’t know. And if you approach it from a point of view of efficiency and optimization (to no end) you never will.

Hello, sweetkins! Love that curious little face. 😻

Hey folks, I hate to do this but I have a birthday around the corner and what I'd like most of all right now would be to know for sure my phone won't get turned off on the second.

Excellent! I should dig up the essay my literature professor mother wrote about parallax...
astroprofhoff.bsky.social
And observations of binary stars like Algol, which I was happy to see in your stellar evolution spread -- I studied a similar system for my Ph.D. and made good use of the fact that our viewpoint on it changes as it rotates.
astroprofhoff.bsky.social
Ahhh, fun! We haven't done that step yet, but it's a good reminder that we have the data for it!

Also, love the connection with multiple perspectives... I think about that a lot with respect to astronomical parallax.
astroprofhoff.bsky.social
Then we went outside and measured people's shadows to calculate the Sun's position. 😄😎

I'd love to see it! BTW, I used your foldable syllabus in my first class meeting and my students enjoyed it. I'm trying to emphasize direct physical experience (of the sky, since it's an astronomy class) and it was a great intro to that approach.

🧪🔭 Really enjoying exploring this comic-style summary of stellar evolution!

Finished spread! The lives of different types of stars, the various ways they give back all they had taken in changed, and the new forms they give rise to! This took me some time to say the least! It's a lively place out there! On to the next spread (finale of this chapter!!)
#Nostos #Unflattening 2
a spread for a comics page, black background, with white panel borders and most the drawings white on black. upper left of the spread, a swirl of the start of a star - emanating out from it in radiating arms, a number of different paths in brick-like interconnected panel border shapes. First radiating down and to the left the life of a brown dwarf - which never quite becomes a start. the next branch goes mostly down - a red dwarf which burns longer than the current life of the universe, but the path forks near the bottom, because some of these alternately flare up during their life. the next path is a dwarf star - much like our own - which is stable until it puffs up late in its life, then burst off much of its material to become a white dwarf. Here the path forks - in one branch it lives on as a white dwarf and nebula, in the other, when it has a partner star, it steals material from it and eventually becomes a type 1A supernova. Overlaid a bit on this set of paths and the red dwarf is an example of a binary star system and a six star system. Emanating from the middle of these paths from upper left and going across the spine of the book to the lower right, is a path filled with galaxies - the path loses its border in the middle showing a collection of galaxies. Upper right path is a blue super giant as we move right it goes nova becoming in one forking path a black hole, in another a spinning neutron star - and that forks to either continue or if paired, collide to go supernova and create heavy elements. Middle of right side, molecules formed by chemistry with these atoms forged in stars. new swirls form, and then we see another generation of stars in a grid set of panels and the Planets! formed around them. This is a generational cycle and the text reflects that

As a stellar astronomer, I love this! Well done.
