What is the newest installment of 'Random Thoughts' on Physics Forums?

Hmm. It seems some of the old Indiana Jones movies are streaming on Netflix. I might just re-watch one of them tonight.

I keep getting reminded of Indiana Jones and the Temple of Doom with Facebook's new care emoji:

Kali-Ma!

Whom did you want to write anus?

Reminds me of a speech Queen Elizabeth II gave a few years ago broadcast on BBC and Newshour. To emphasize the serious nature of her comments she reverted to Latin. In a shrill British accent her majesty intoned:

"This horrible year, truly my annus horribilis!"

I literally spewed my seltzer water across the table on to the remote control.

"What did she just say?", wiping furiously.

With her strong accent her Latin sounded like horrible anus. Stifled laughter can be heard in the background. I think she meant to say, "anno meum horribile".

Don't know if it was a joke or made-up but this guy told me that, while at the hospital recently, he asked the doctor: What happens when we die? Doctor replied: " We clean the bed and give it to another patient". Interesting bedside manners.

Looking for a replacement battery for my hp. Seems absurd how they have thousands of models for their hp laptops. And battery codes are some 40+ terms alphanumerics.

The costs for the battery are probably half the costs of a new laptap.

Not quite. Some sell for $30-$50 each.

I once looked for a replacement and they called $150, but that was 15 years ago or so.

If I had more $ , I would pay that to avoid the hassle of looking through 1000s of model+ alphanumeric strings with some 60 characters.

An IT friend told me discount HP color inkjet printers cost about the same as ink replacement cartridges. When they exhaust the ink, they trade the used printer to a second-hand store for credit on cables, batteries, paper and other supplies. They buy a new printer from Walmart that also figures in their taxes as a business expense.

I checked the local store they use. New printers cost ~$30 USD. Replacement HP ink cartridges cost $45 USD. Perhaps the latter cartridges have more capacity (?) but the $40 wireless color printer I bought came with inkjet paper and latest HP software; also copies, sends and receives faxes and prints for every wireless device in my home office including laptop, TV, phone and digital cameras. Have yet to use up the ink.

Ink may end up drying up unless it includes some special ingredient. I would call my ink company Ink Inc, ( Wink!).

That sort of reminds me of Valve Corporation, but for the opposite reason.

For those who don't know, Valve Corporation is the software company that created/owns Steam (a place where many/most PC users get their games these days). They also created Half Life series, Portal series, Counter-Strike, Left-4-Dead, and other games.

Anyway, the official name of the company is "Valve Corporation." But it's not a corporation. "Corporation" is just part of the company's name. The company is actually a privately owned L.L.C.

I heard of this company that named itself ' Going out of Business' and so they have 'Going out of Business ' sales. Seriously.

YAY! I went to the grocery store yesterday (don't tell my daughter). I found toilet paper, paper towels, flour, rubbing alcohol, BUT that had been relabeled as HAND SANITIZER and a 98 cent bottle was selling for $8! It was just plain rubbing alcohol, nothing else, just a different label! That PISSED ME OFF. But I bought it, it was all they had. :( I may go after them for price gouging. Nice to see the shelves stocked again.

This has got to be the worst mnemonic I've ever seen

This is known as triple product expansion... Its right hand side can be remembered by using the mnemonic "ACB − ABC", provided one keeps in mind which vectors are dotted together

Well thanks for that, Wikipedia.

I had a professor who started to write at the most left edge of the big boards at university with his left hand until he came to the center where he changed hands and continued writing to the most right edge with his right ...

It was almost impossible to script the lectures.

I had one that was scary. Once, after writing a full blackboard and erasing it, a student told him she had missed something. The prof wrote the notes again identically on the blackboard.

Students of von Neumann coined the term: "proof by von Neumann" because he was so fast, that he had to start wiping before the students had a chance to write it down.

There is always the 2-step-emergency-plan;
1.) If in doubt, add bacon.
2.) If still in doubt, cover it with cheese and bake it.

Bacon makes everything better. Now they even have it with chocolate. Notice no bacon-eating competitions. People would never stop eating.

It is a crackpot discussion. There is no ambiguity as soon as notation has been properly defined. It's a debate for hobby calculators.

No, there are actual issues if you work with Hyperreals or Surreals without the Archimedean property. True that it is settled within the standard Reals.

You know how maps like that in fantasy novels never look quite plausible? I strongly suspected I'd enjoy Juliet E McKenna's books the instant I picked one up, because the maps of her continents had long narrow triangular cutouts, so you could have cut them out and constructed a partial sphere (or polyhedral approximation to one, anyway).

This version seems to have the maps crossing the cutouts, but the version in the books doesn't.
