J'aime la science, l'espace et la lecture. Et aussi les jeux vidéo.
Another cracking @vrubinobs.bsky.social shot, found while writing a piece about this utterly awesome new observatory. A shame that efficient modern-day astronomy doesn't need oldies like me to go and collect the data. I would so love to visit this site!!! 🔭

Had 2 scopes running Wednesday night but only got an hour before clouds moved in. Pickering's Triangle and Eastern Veil Nebulae, a small part of of the Cygnus Loop. 🔭 #astrophotography

The Eagle nebula.
Got a couple of images last night. The Crescent and Eagle nebulas. These aren't processed much. They will look better after I work on them after my trip. Southern Oregon, Bortle 2 skies #astrophotography

When viewing #Perseids this year the Moon interferes quite badly on the peak night of 12-13 August. However, plenty of meteors will still be visible and it is entirely possible to capture some on camera. Here's a shot from 12 August 2022 when the Moon was just past full. #Astronomy

85% of Gaza is on the brink of death due to starvation. Israel could let aid in at any moment. And some people (like these men tried to do with me on Friday) are still trying to justify this atrocity.
There is no justification. This could stop at any moment. End the blockade now.
I only recently found you on YouTube and though I don't have much, I have already started donating where I can when I can to you. You make my belief that there is still some good in this world not seem naive, because it's there and you're a shining beacon of it right now. You have my support ♥️

The fact this fuckhead in charge openly attacks an enormous portion of this country he is supposed to be leading is so fucking shameful and utterly disgusting and people wonder why we can't shut up about it.

She is set against the colors of the transgender pride flag in a circular background. Below her portrait, the words “FRIEND OF DAX” are prominently displayed, with “DAX” in large, bold, golden-yellow lettering.
Jadzia, my beloved old friend!

05.04.2025 19:21 — 👍 6 🔁 1 💬 1 📌 0Nous avons vu que l'équation de Dirac prédit qu'il existe une interaction entre le spin de l'électron et le champ magnétique, SB, avec une force µB = he. Lorsque l'électron 2me a un moment angulaire L, comme dans une orbitale atomique, il existe également une interaction BL et un couplage spin-orbite SĨ. L'équation de Dirac (ainsi que des arguments de symétrie) prédit la force de ces trois interactions, ainsi que d'autres corrections. Pour voir l'effet de ces termes sur l'atome d'hydrogène, nous devons prendre la limite non relativiste.
(a) Pour l'équation de Schrödinger, nous avons besoin du hamiltonien et non du lagrangien. Trouvez l'hamiltonien de Dirac en écrivant l'équation de Dirac sous la forme ίθιψ = Ηρψ. Ecrivez le hamiltonien en termes de moments p₁ plutôt qu'en termes de dérivées d₁. (b) Calculez (HD + eAo)2 dans la représentation de Weyl pour 4 = (LR). Laissez les termes de oi, pi et A₁. Remettez les facteurs de c et ħ, en gardant la charge e sans dimension. (c) Prenez maintenant la racine carrée de ce résultat et développez-la en soustrayant l'énergie du point zéro mc², c'est-à-dire calculez H = HD-mc² à l'ordre co. En regardant le terme σε, quelle est l'importance des moments dipolaires électrique et magnétique de l'électron ?

The artwork is signed “TANA ’23” at the bottom.

My latest videos aren't exactly super great because my mic had an accident involving my cat.
I don't have Twitter and I wanted to say it for a while now but not comment it on your channel(because it would feel like self advertisement) but I love your content and you made me feel more comfortable with making videos on Zelda and my own channel has been growing steadily. Thank you ❤️💙💚

Exhibit B: In "King Pascal" Raps and Cass build their island hut next to a jungle colored like the lesbian pride flag.
Exhibit C: "I'd Give Anything" is a song of longing that Raps sings for/about Cass.
