This flower is called a Poinsettia in English. September is the best time to discuss the name's connection to colonialism and why I would never call this plant a poinsettia.

Bsky hasn’t heard the story about the time that I was giving a virtual colloquium to the Aspen Center for Physics in September 2020 and Lawrence Krauss, Geoff Marcy, Christian Ott all attended as a group

I am very worried that the news coverage of the protest I have seen in CNN and DW are very carefully omitting the n@zist paraphernalia of the protest for the sake of framing this as "anti-populism/anti-socialism" narrative.
Si yo fuera generación Z me deslindaría de esta basura nazi. Y no, no es hipérbole. En cualquier movimiento que se respete, si hay una persona con una playera que tiene la suástica nazi y alrededor hay una multitud que no le dice nada, entonces no hay un solo nazi: hay una multitud de nazis.

Aunque digamos que la ciencia se «autocorrige», en realidad carecemos de un mecanismo para detectar errores: hay errores que se descubren por accidente, otros que no se corrigen y otros que se ignoran.

Trump: "why is it called Gulf of Mexico if we own 92% of it..."
He could just say "because I wanted so". But in his fantasy world he needs to have a reason that seems fair and in that fantasy world, of his own creation, having 44% of the shoreline is not a good reason, so he lies. What a sad man.

The Gulf of America is now the name for the northern portion of the Gulf of Mexico which sits on the Mexico Basin. Now is the time to be as pedantic as you can and journalists are dropping the ball. Sheinbaum already explained this in her morning press conference.

A new study sheds light on how these reptiles become “mummies” and paints a picture of what these ancient animals looked like.
