I need to disconnect for a few days. All my love to folks being reminded of too many things. Be kind to yourselves, be gentle to yourselves. ♥️

I hope Jane Doe can, eventually, find some peace. I imagine it will take a while. This week I have been remembering an experience in college where “nothing happened”. A near miss, I was merely lucky. Even those “nothing happened” stories stick to you; the allegations made here are horrific.

You know, I wouldn’t have thought it would be so hard to find tall sweaters made from natural fibers, but here I am staring at one shop with import taxes or making my own. The internet is failing me.

The image is of a four panel comic.
In the first panel we see Sarah, the protagonist, next to a stick figure labeled “AI”. The stick figure says, “my outputs look just like yours now.”
The second panel zooms in on Sarah’s face. Above her we see text reading “I think”.
The third panel zooms in closer on Sarah’s face. Text above her reads “you missed”.
The fourth panel shows Sarah drawing happily in a sunlit room. The text above her reads “the point”.

Wow: Giant new impact crater spotted on the Moon! An asteroid the size of an apartment building hit the lunar surface in early 2024 & created 220-meter (730-foot) wide McGetchin crater. It's "the largest contemporary impact crater found in the Solar System." 🧪🔭 science.nasa.gov/solar-system...
Officially named McGetchin after pioneering lunar scientist Tom McGetchin, the crater formed on the Moon’s eastern edge sometime between April 11 and May 22, 2024, after a comet or asteroid the size of a three- to six-story building hit the surface.
 
The crash left a crater, 728 feet wide, that spans the length of two football fields. And at 141 feet deep, the crater could fit three vertically stacked yellow school buses. Scientists estimate that an impact of this magnitude happens on the Moon about once in a century or even longer.

Saw a new doctor recently who tentatively asked about my experience with another doctor in my file, responded to my 😬 story with “PLEASE report this”, and handed me the docs on how to do that. One thousand blessings on new doctor’s household.

CHAPTER

1

The magic in that country was so thick and tenacious that it settled over the land like chalk-dust and over floors and shelves like slightly sticky plaster-dust. (Housecleaners in that country earned unusually good wages.) If you lived in that country, you had to de-scale your kettle of its encrusta-tion of magic at least once a week, because if you didn't, you might find yourself pouring hissing snakes or pond slime into your teapot instead of water. (It didn't have to be anything scary or unpleasant, like snakes or slime, especially in a cheerful household magic tended to reflect the atmosphere of the place in which it found itself-but if you want a cup of tea, a cup of lavender-and-gold pansies or ivory thimbles is unsatisfactory. And while the pansies-put dry in a vase-would probably last a day, looking like ordinary pansies, be-fore they went greyish-dun and collapsed into magic dust, something like an ivory thimble would begin to smudge and

crumble as soon as you picked it up.) The best way to do it was to have a fairy as a member of your household, because she (it was usually a she) could lay a finger on the kettle just as it came to a boil (absentminded fairies could often be recognised by a pad of scar-tissue on the finger they favoured for kettle-cleaning) and murmur a

V cranky because of redacted medical reasons no one needs to experience [I regret to have experienced them] but in good news my book is out in six days and you should preorder my graphic novel tour of the entire* universe *some exceptions 🧪🔭💙📚💡
The front cover of The Universe: A Graphic Guide, which has a person looking up at a sky full of galaxies, standing on a winding path with trees. Back cover of the book, which reads “This beautifully illustrated journey through space and time is a celebration of all that is wondrous about the biggest topic of all - the universe itself.
The building blocks of life are here, alongside the mysterious dark matter, how stars are classified, the creation of the moon and other concepts that illuminate our understanding of the expanding cosmos around us. Have you ever wondered why a star collapses? Or what Cosmic Noon was? Then this is the book for you.
Dr Jillian Scudder is the perfect intergalactic tour guide. Aided by Lily Fossett's illustrations throughout, she explains some of humanity's greatest ideas and discoveries in an accessible way, making this the perfect primer for anyone who has ever wondered how we fit into the universe.”
