260 years ago, on the 2nd of October 1766, ‘Cheese Riots’ broke out at the Nottingham Goose Fair after Lincolnshire merchants had bought large quantities of cheese with the intent to sell it back home. The residents of Nottinghamshire did not want food to leave their county. #otd #history 🗃️

The two #Equinox are the only days when the Sun rises due East and sets due West, everywhere. At the Dec solstice the sun rises in the S-East. At the June solstice it rises in the N-East. As the days pass between the two, the sunrise position slowly changes passing due East each equinox.🤩 🔭🧪

This is why I think it's so important to push back against the personification of LLMs. If a person shoots someone while wearing a hand puppet, they can't claim the hand puppet did the murder.

Anyway TL;DR a "sex cult" is a cult that weaponizes sex and has sex at the core of its rituals and exploitative dynamics. A cult where people are sexually exploited is just... a cult. Sexual exploitation is everywhere.

It's a popular astronomy cliche that there are more stars in the universe than there are grains of sand on all the beaches on Earth. Hard to visualise that, of course, but look at these two images with very different fields of view... Mind-blowing, right? And very beautiful too, I think...

God says to a man "you have died. Prepare for judgement. You will now confront your best self. The version of you that lived up to all your potential." An exact duplicate of the man pops into existence and says "hi, it's me! Your best self! I'm exactly like you!" He continues "turns out youa ctually did live up to all of your potential!" The original man puts his hands on his head and says "Jesus, that's depressing."

Wake up, babe. The Prime Minister just dropped “hydronym”.
The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means “the lake is beautiful, the lake is big”.

The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America.

We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms. 

Canadians also know that naming reality means calling it Lake Ontario – then, now and always.
