Anglo-Saxon historians, can we just agree that the world would be a funnier place if we all said that Aethelred the Unready was actually unready for his responsibilities, and not just poorly advised or whathaveyou?

If you ever submit a paper to the journal Soft Matter, do not use the word "via" at all, or else the editors will italicize it and make you look like an idiot who italicizes random words in the middle of sentence for no reason.

@mscommunity.bsky.social if Windows 10 support has ended why are you still externally restarting my computer to install updates? That's the whole benefit of no more support, I get to use my computer as I like!

Told a border guard I was a physics professor and he had me tell him the equation for force before letting me back into the United Kingdom.

Why are you, as a conference organizer, asking for a 500-800 word abstract.

The @canjphysics.bsky.social just followed me and this reminded me of the time about 10 years ago that my paper was rejected there because the referee thought I should acknowledge that he was on the path to win a Nobel prize in high school.

Three major problems that have been solved in my lifetime:
-ozone depletion
-acid rain
-USB plugs that are always upside down the first two times you try to plug them in

New preprint with Ryan Blair and student Jonathan Strange, developing a new way to detect if ellipses form Borromean rings. It is 150 times faster than using the Jones polynomial!

What would this scatterplot look like? On the x axis is the mass of objects from electrons up to tanker ships. On the y axis is the fastest speed humans have managed to make it go.

Reading "Termination Shock" by Neil Stephenson and I find it funny that even though the book is about dealing with a global environmental crisis, he takes every opportunity he can to point out how stupid he thinks environmentalists are.
