As I follow it, you go from the 1500s Italian game "mallet ball," or "pallamaglio," to the French "pallemaille," to the English name of the game, "pall-mall," to an area where you would play pall mall being called a "mall," to a walking area that you could play pall mall being called a mall, to an indoor shopping area where you walk from store to store being called a mall, to a person who hangs out at the shopping area being a mall rat—the term "mall" all coming from the Italian and then French term for a mallet used in an outdoor game several hundred years ago.

People say a lot of nonsense about Gödel's incompleteness theorems, which presumably is only going to get worse because AI made the topic fashionable again, so if you want to learn more about them I strongly recommend this book. Not only does it explain the math, but it also discusses the philosophical implications and covers various related topics, such as Tarski's indefinability theorem, Turing machines, undecidability, the halting problem, the Church-Turing thesis, etc.

Thanks to my recent surgery, I do have a slightly gnarly scar on my arm, but I don't think there's any degree of advantages that can spin that episode as a victory...

This is like the epigraph for the entire Trump 2.0 presidency: ‘’I don’t give a damn. We’re making a fortune’
TRUMP on HIGH GAS PRICES: We’re making money like we’ve never made before. They’ll say: President Trump is bragging about all the money they're making while people are suffering at the pump. I don’t give a damn. We’re making a freaking fortune.

We're visiting SteelyKid at college, staying in a chain hotel, and the TV in the room doesn't have a Fox affiliate on the cable, so I can't watch the World Series. Somebody needs to be sent to Guantanamo Bay for this...

They've got Fox News if I wanted crazy people yelling at me, and FS1 running a college football game, but no regular Fox with the World fucking Series. Why does the Marriott company hate America?

you just do it. I know everyone hates to hear that but there’s no secret. pick a book you’ll enjoy and put your phone in another room and do it even when it seems hard. and then do it as often as you can.
People who read books for fun in the big 26, genuinely how do you do it. I salute you your brain is made of sterner stuff than mine

It has to come from faculty. Education begins with scholars and teachers. That doesn't mean it *will* come from them. Just this: if there will be successful reform, it can only come from faculty.
The basic question I have for pro-liberals arts higher ed. reformers is this: where, exactly, is change going to come from? It’s certainly not going to come from administrators. Almost certainly not from faculty, either. And it’s not going to come from students or parents.

Sad news today. After 5 years of medical training, one of my mates has been struck off due to a minor discretion. He slept with one of his patients and can no longer do the job he loves. What a waste of time and money. Genuinely a great guy and a brilliant vet

If you mean two total, The Pip. If you mean two guests in addition to me, The Pip and my dad. (I'm super boring, I know...)
If you had two World Series tickets and knew whoever you invited to go with you would accept, who would you ask?
