Galaxy Map @galaxymap.bsky.social · 1d

One of the things that I've learned over the years is to work to create simple versions of my maps. Here is one out to 500 pc that I use as part of a star show in my new VR world launching at the end of the month.

Many English placenames contain 'mere', a word that's not often used anymore. It means "body of standing water".

'Mere' is closely related to German 'Meer', whose meaning is now "sea" but used include "lake". Conversely, Dutch 'meer' now only means "lake".

President Luiz Inácio Lula da Silva, leader of Brazil, gave a brave, empassioned anti-autoritarian speech at the United Nations. Worth a listen. His speech sounded very pointed at the Trump regime - from pedophilia to Alaska meeting. "We are experiencing a time of global polarisation".

Vi alguém criticar o fato de que tem que ir os grandes velhinhos de 1968 pro palco.

Por outro lado: imagina precisar aos 80 anos dizer de novo o que se disse aos 25.

Imagina ter uma fatia da população querendo uma ditadura como a de 1968.

E os populares de hoje querendo tchu, tcha e golpe.

🇧🇷 Na manifestação contra a PEC da Blindagem e o PL da Anistia, Chico Buarque e Gilberto Gil cantam “Cálice”, música feita na ditadura como um paralelo a “cale-se” para driblar a censura.

A canção se tornou um símbolo da resistência contra a repressão e marcou gerações.

A nearby, burned-out star is eating a fragment of a Pluto-like object. Only Hubble could identify that this is taking place with its unique ultraviolet vision: https://bit.ly/4mZk6sx 🔭 🧪

An illustration showing a glowing white object in the upper left corner. This object is encircled by hundreds of thin, concentric, pale-yellow rings on an angle from bottom left to top right. The rings are palest closest to the central, glowing white object. A curving trail of gray, rock-like fragments marches across the right side, through the thin rings and joins the rings at far right. The eight largest fragments of varying sizes appear in the foreground. These objects have white, comet-like tails streaking away from the glowing white object in the rings’ center. The curving trail of fragments bends toward the glowing white object. At the bottom left corner is the label Artist’s Concept.

O comitê de publicação científica da SAB já fez isso no ano passado. Eles contactaram o CA da Física/Astronomia e alertaram para a necessidade de usar outros indicadores nas avaliações. Foi feito um relato sobre essa ação na assembleia geral da última RASAB.

Sim. É uma das que recomendamos. Além disso há um acordo de publicação aberta nas revistas da AAS em negociação com a Capes.

You are not helping to balance out the predominately right-wing population on twitter by remaining there. The system has been retooled from the ground up to suppress opinions contrary to Musk, while you funnel more money to his pockets.

LEAVE TWITTER

Jack McGovan @jackmcgovan.bsky.social · Sep 15

No matter what #Musk says or does, many on the left continue to post on and pay for X, a clear example of how progressive movements are beholden to the narrative that we don't have to change anything at all about our lives to achieve our political goals.

I wrote about why that's bad in July ⬇️

X reveals a weakness in left-wing rhetoric

Good principles mean nothing when you materially support a fascist propaganda machine.

False friends are often wrongly called false cognates. These are very different things.

For example, 'to molest' is a false friend of Spanish 'molestar' (to annoy) but they are true cognates, both coming from Latin 'molestāre' (to bother).

Four graphics, all about false friends and false cognates:
