Turkish Lentil Soup (Mercimek Γ‡orbasΔ±) Turkish Red Lentil Soup (KΔ±rmΔ±zΔ± Mercimek Γ‡orbasΔ±) is velvety, comforting, and nutritious! Plus, it’s so easy to make with lentils, veggies, and spices!

Hah! I literally just made the lentil soup (which I have been thinking about since I got back from Turkey lol). Here's the recipe I used. I'm eating it right now and it tastes exactly the same. I found the pul biber at whole foods ("silk chili") www.themediterraneandish.com/turkish-lent...

Thank God!! I was just there and saw all the racist "this is not Bangladesh" signs everywhere. Glad that piece of shit got stomped down. Portuguese people have always struck me as collectively very level-headed.

As a recent PhD and adjunct teaching faculty at a public inner city college in the US I can attest that the general vibe is that of the musicians on the Titanic: we do what we can almost as an act of rebellion but we all know the ship is going down.

worth noting that the second rich people stopped being afraid of mobs tearing them limb from limb, they stopped building libraries and opera houses and stuff and started ripping the copper wiring out of the walls of society instead

Sorry to derail the thread but these are really nice notes! Do you know if there is any connection between quadratic forms/grothendieck-(a certain nazi) rings and Clifford algebras/topological K-theory rings? Just because both involve quadratic spaces.

Not just any journalist, she won the goddamn Triple Crown of broadcast journalism (an Emmy, a Peabody, and a Murrow) in 2024 for her reporting on Gaza.

Detained by ICE, two women became first responders during agent’s seizure The women say they guided agents through the emergency, later raising concerns about medical protocols, weapons safety and accountability.

Two women trained as first responders were abducted by three ICE agents. One of the agents starts seizing. The other two don’t know what to do. The women jump into action and save the agent’s life, only to be re-handcuffed and processed.
