Has this been a soul-searching moment for the fact-checking industry? Everything Harris says came, or is coming, true. And so much of it was labeled as "misleading" or "lacking context" at the time, on the grounds of "but he said he wouldn't!" (see, e.g. www.npr.org/2024/08/25/g... from @npr.org)

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link) www.theatlantic.com/ideas/2026/0...

During the pandemic, the US implemented the most effective social welfare policies in our history -- programs that worked because they were big enough, simple, and universal. And then we withdrew them. This remains imo the central economic-policy story of our times. davisvanguard.org/2025/05/3hou...

We have had nearly two decades of panic about Free Speech on Campus and not a single case, not even the ones they made up, were as bad as what's happening now

This is a good thread by one of my "trusted sources," @polotek.bsky.social.

So. I think it's important to share news about what's happening. But I'm trying to square that with the other reality that it contributes to doomscrolling. I think we need to start putting these things into context and talking about what we are learning or what we should take away from it.

I’m here.

Enjoyed re-creating this visual in the @desmos.com Geometry tool: www.desmos.com/geometry/lx7... #mathsky

(a) stunning visual. (b) any differential geometers able to weigh in?

according to @merriam-webster.com the first usage of the word “sewerage” dates back to 1834. other words first used that year include humoristic, optimistic, and self deprecating, and i feel like that explains so much.

Can you find a Pythagorean Triple containing... • exactly one multiple of 5? • exactly two multiples of 5? • three multiples of 5? • no multiples of 5? Any conjectures? #iTeachMath #MathSky
