As someone who understands governments' current flaws all too well, I would NEVER tell anyone that "you must vote." But for New Yorkers ALREADY planning to vote, I ask that you vote for ✨Kathy Hochul on the Working Families Party line.✨ Here's how doing so will help build Left governing power. 🧵

I don't know if history is going to repeat itself. However, I will note that the Gilded Age begat the Progressive Era. ... I will also note a new poll by the Associated Press that suggests the emergence of a new consensus in which Trump is becoming symbolic of our own 21st-century Gilded Age.

In the latest Digging in the Dirt podcast, I talk with @digginginthedirt.bsky.social about the developing super El Niño, the Nor'easter that washed out the coastal highway to North Carolina's Outer Banks, and the future mass migration of people from the coast because of climate change.

No matter where you shop, you're getting screwed by Amazon. Amazon has found a way to make everything you buy - at Target, at a mom-and-pop shop, even direct from the manufacturer - more expensive. And they're not the only one: Expedia's done the same thing, but for hotel rooms.
Let me repeat that: to stay in business, hotels need to be on Expedia. To stay in business on Expedia, hotels have to raise their prices to pay Expedia's junk fees, but they have to raise their prices everywhere else.

You have one week left! I’m sending someone these mittens. Maybe it’s you! Please share.
Annie loves Mpls@anniekp.bsky.social · 2w agoYou want these sweet mittens? Register people to vote or give to down ballot candidates and I will send them to one of you so you can wear them on Election Day. Send me nothing except a screenshot of your voter registration event or of your donation. More threaded.

Here's a story I was forwarded about how AI-usage in mathematics helped bring together a team of mathematicians to broaden human understanding. The text below was written by Leandro Vendramin on who has given me permission to share it. The paper referred to is here: arxiv.org/abs/2610.10144 1/4
Higher Fomin-Kirillov algebras are infinite-dimensional
We show that the Fomin--Kirillov algebras $FK_n$ are infinite-dimensional for $n\geq6$. This answers a question posed by Fomin and Kirillov in 1997. To prove this, we demonstrate that the Nichols alge...

Conservative government of Alberta is preempting Edmonton, requiring the city to: —Reverse the city's 2024 change allowing small-scale apartment buildings to be built citywide. Change resulted in a building boom: www.cbc.ca/news/canada/... —Restore parking requirements, which city eliminated in 2020
Courtney Theriault@ctheriault.bsky.social · last wk.BREAKING: Premier Danielle Smith announces province will direct Edmonton to adopt infill housing rules that were in place before 2024, and require Calgary to maintain its current pre-2024 bylaw framework.
As this excellent story notes, the city probably should reconsider Lyft's monopoly and allow a dockless bikes such as Lime. I've come around on the idea and think the wider availability of bikes would not just spur some competition but would also be a catalyst for the further growth of cycling.

Tomorrow, Friday, October 9th, we will have our next #illustratingMath seminar online at 9am Pacific / 12pm Eastern / 6pm Central Europe. Things will be slightly different than usual: Instead of Show&Ask and a talk, we will have a panel on "The Role of Illustration." Tune in!
Sometimes my wife and I like to send each other text messages as though they’re democratic fundraising messages, and I believe she has produced the jewel of the form.
I love doing these events so much! Wdym I get to speak to a room full of young mathematicians and hype them up to stay dedicated, find joy in maths, and go out to do things in the world?! 🥹💗🌍
