So Jurassic Park is about a group of rich people who don't understand that biology is far more complicated than "there are only two genders" and how this ignorance toward gender fluidity in nature causes these rich people to lose their money and die.

I think I'm just going to start using the phrase "hobbledeegobbledeecastle - what is it?" whenever something ridiculous happens or I don't know what else to say
We undertake lots of serious historical research, but this may be the most important of all:

what in the *blue hell* was the “Hobbledeegobbledeecastle” in the Crystal Palace North Tower Gardens? Even this 1910 programme doesn’t know

(The one from 1908 simply calls it “The funniest thing on earth”)

- you clean up that banksy?
- sure did, your honour, leaving a perfect, permanent outline, imbuing the work with real fuckin gravitas while making its point better than the artist did himself just like you asked
They erased the new Banksy mural in London. But the stain remains.

This is a new image of comet 3I/ATLAS, showing the development of a long tail of dust and gas as the object gets closer to the Sun.

As a reminder, the "I" in 3I/ATLAS stands for "interstellar".

Because this comet formed around a different star and is OLDER THAN THE SOLAR SYSTEM

In 1988, IBM tried to seize the whole PC market back and make it proprietary again.

Everyone KNEW you couldn't win against IBM. Compaq, and founding CEO Rod Canion, decided to try.

Read my latest #history longform on the fight for the soul of the PC. And how Compaq won.

Happy Pride month, all! Way back in 2018 I made these galaxy pride flags. They were shared many thousands of times, featured on Vice, and even made their way onto book covers and into video games.

Here are the original ones I created (in no particular order!) so Bluesky can have them too. 💙

A science communicator launched an effort to pair artists with scientists whose jobs were eliminated or whose research funding was halted by the Trump administration. The result? Powerful portraits of researchers and their work. ⚛️🧪
