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

In summary, the conversation consists of various discussions about documentaries, the acquisition of National Geographic by Fox, a funny manual translation, cutting sandwiches, a question about the proof of the infinitude of primes, and a realization about the similarity between PF and PDG symbols. The conversation also touches on multitasking and the uniqueness of the number two as a prime number.

I would have preferred if he had used " Me Space". Please tell him if you run into him.

A friend claimed that this was the best way to get something named after you - discover something and give it a clumsy name. Other people will start using your name as a shorthand...

Do not promise this! Nobody really knows how liability cases are dealt with in the other realm!

I was slightly embarrassed not to know the Kato-Rellich Theorem, because I learned from Kato's book, where it is Theorem 4.3, with a footnote: "Theorems 4.3 and 4.4 are due to RELLICH [3]. See also T. KATO [3], [4]".

Same with a few other theorems of his.

Well, you're way ahead of me by that account. I was not even aware of the author himself.

I do remember, though, this sort of funny anecdote ( at least for me). I have only cursory knowledge about literature. Once I was talking with this literature professor and the line " It was the best of times, it was the worse of times". It was one of the 3 things I remembered , that it was from " A tale of two cities". The prof misidentified it, yet I got it right. It was awkward ; any other exchange would have shown him to be greatly more knowledgeable than I in this area.

It reminds me of when Putin's child was trying their clothes at the store , he was a little Russian dressing on the side.

does anyone know if you can go to sleep with your phone under your pillow? was going to start waking up a little earlier but don't want to start irritating everyone with that obnoxious radar sound. :nb) it's not going to, like, overheat and catch on fire or anything?

I wouldn't do it. Besides the small chance it catches fire, I like to limit prolonged close proximity exposure of my phone to my head, just in case.

Can you plug headphones to your phone and put it aside?

I would not worry about a fire or explosion.

Why not turn just down the volume.
On the other hand, certainty of waking at the proper time is not nothing. I used to be on-call 24 hours a day for a vision critical job (eyebank) and kept my phone in a large ceramic cup by my bed. The cup provided amplification (I guess through resonance). I wanted to be sure it woke me. It also woke my wife, but she wanted to keep track of me anyway.

Nevertheless, volume control should provide a happy middle path, once calibrated.
The earphones sound OK, if tolerable, but that might be a temporary problem anyway.
I have found that if I want to wake at a certain time, on a regular schedule (and get enough sleep), I will adapt to the new wake time after a few days, and awake then anyway, due to the resetting of my internal alarm clock.

You could switch to an IPhone. The alarm is so traumatizing that you just have to set it and your subconscious will wake you up in advance to disable it; works for me.

Or you can ask two people ( just in case) to call you at that time.

When writing this I remembered of someone called just that: Justin Case. Don't know if the parents were careless or just missed it.

Apparently one of the unofficial duties of a midwife is to enquire if you've thought about names and try to guide you away from anything that's going to get the kid bullied. The person who told me this said she'd managed to dissuade Mr&Mrs Trickey from naming their son Richard while Nixon was still alive, but had not managed to get Mr&Mrs Lamb not to call their son Shaun.

Any one but me find it impossible to find a nice article on the greenhouse effect...
That actually takes place in greenhouses?

(And cars, bottles and apartments with really big windows...)

Not just midwives.

Depending where you live there are people with legal authority to tell you "No, you can't name your child that!"

And immigration officials can allow/encourage you to pick a suitable name in your new country's language. I've seen examples where that didn't happen.
