This week, the world’s human #population is expected to reach 8B. About 109B people have lived and died. Each grain of sand represents 10M.

Lake Louise was once a wild outpost where the Canadian Pacific Railway's rail routes terminated. Today this village, the lake and its surroundings offer some of the best hiking, skiing and sightseeing on Earth. Lake Louise and Moraine Lake generally melt in late May. The alpine hiking season starts at the end of June, you can also take pictures of.....

When a snowball becomes a moon: When enough stuff accretes onto a body within Saturn's rings, they can become a Shepherd Moon. These moons rule over their own ring gaps. They also shepherd the rings, keeping them in order. If they have enough gravity, they can create disturbances in the edges of their gaps. Daphnis orbits within the Keeler Gap and as the material passes it the moon gives it little tugs creating rhythmic waves.

ADHD life
#adhd is hiding the only meaningful jewelry you’ve got in a “safe place” because contractors are going to be coming in and out of the house and then one week later not being able to find them and getting upset and then spending an entire YEAR fighting the upset because you know you put them *somewhere* and then one day randomly finding them in a desk drawer you’ve searched like 30 times since then. Every day brings a new little gift - set up by your previous self long, long ago. Today it was my grandmother’s pearls.

#Threethings for Sat Nov 12:
1. Astounding image from the #Mars Curiosity rover, via Kevin Gill who is Kevinmgill on the other place. It looks like a landscape one would have fun exploring.
2. Speaking of Mars, it was glorious last night with the #Moon close by in Taurus Did anyone else spot them?
3. Had a amazing, moving, raucous time with #bellowhead in #Oxford last night. Best live band anywhere? Possibly. #Folk refracted through all sorts of lenses. Go if you can. #astrodon
Happy to share my most recent paper about course modifications to support student mental health in the physics classroom. I never feel like I do enough, and my collaborators and I wrote this as a reminder that even modest changes are valuable! #ITeachPhysics #MentalHealth
Here’s my favourite photo of the Australian night sky. The #Australian #indigenous peoples identified the “constellation” of “The Emu” - an outline formed not of stars but from the dark clouds of dust that obscure the Milky Way. You can clearly see the image of the emu in this one, with the head at the top right. This was taken in 2020 from Ebor Falls in New England, NSW #nightscapes #photography #astronomy
Wow. This needs to be read by everyone who joined Mastodon in the last week: https://www.hughrundle.net/home-invasion/
US Politics
I grew up in rural Pennsylvania and my entire family is still there (and most are still trump republicans ). I have little faith in electoral politics but thank god #Fetterman won the PA senate seat. Every once in a while, PA does something right, almost in spite of itself.
