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.

How do they give mice tumors in labs?

Over 100 million are killed in lab experiments in the US alone each year. I doubt they waste money on anesthetics either.

what a difference a word makes...

in this vein -- if I tell non-mathematically inclined people "I really like decompositions" that could sound really strange, particularly if they watch a lot of CSI, right?

I suppose German speakers will think I'm saying that I like "die Komposition(s)"... so there's that.
Yes, I remember a German ad with a baby telling her mom <Sarcasm/Joke> " Die mamma, die" . Which of course is ready for use outside of Germany without any translation.

Yes, it's kind of disgusting. Can't one use computerized simulations? Besides, has anyone tested to what extent one can extrapolate from mice to people? Maybe that is what the book " Of mice and men" was about?

You can't test for unknown responses in animals with a computerized simulation that would require knowing the unknown responses before the simulation was made.

Mice can be given tumors in many different ways.
There are some lines of mice that are genetically predisposed to developing tumors.
I have done it with an injection of hybridoma cells (kind of a liquid tumor) into the abdominal body cavity, to make the mice make a lot of monoclonal antibody.
I think in many cases, injecting a few cancerous cells of a solid tumor would produce a tumor, given enough time for it to grow.
Injections don't usually require anesthesia.

Yes, I had assumed a history of responses had been analyzed to be able to mimic "standard" mouse responses.

No joke:

I was riding on the muni bus in San Francisco late-ish one night just a few years ago. A passenger standing in front was facing everyone and wearing an all black t-shirt with white letters on it that said "die Techies, die". My first thought was oh, isn't that quaint an American guy with a t-shirt saying "die Techniscie " whatever. Then I did a double take and realized it had absolutely nothing to do with German.

I know very little about this, way less than you, I would just thought that mice are very simple organisms to model biochemically. But I know little about this and I don't want to overstep by spouting nonsense.

Reminds me of a story my English teacher at school once reported. He was on a bus in London and his neighbor started a conversation by: "It's a nice die to die, isn't it?" And no, it wasn't a Klingon.

Nine years ago, I installed wood floors in the living room and on two flights of stairs. I swore that I would never do that again.

Never say never...

This weekend, I started getting ready to install wood floors in all of the bedrooms. The boxes are over 50 lbs each and I carried 36 of them up two flights of stairs yesterday. :oldruck:

Or when I (purposefully) asked for the singular for 'dice' and pretended not to hear the reply, just to embarrass my friend into shouting 'die,!die!, die!'

I think this is part of a Curb episode, where someone sees/ overhears Larry saying this, and he gets in hot water with his dad's nursing home?

Ah, just like faces are starting to repeat --more lookalikes are being found throughout the world -- it seems like the same is happening for jokes, in that the same joke is being created independently in different times, places.

I had to work through this phonetically -- the klingon comment through me for a loop. (Bad callback:) I wonder if the neighbor was from Sydney?

Australian and London sounds very similar, if you don't know them. My nephews can distinguish them, I can't. Scottish is phonetically even more strange. They often pronounce vowels as in languages, which pronounce what they write, i.e. most others. "a" and "o" are so to say "correct".

But I love it when they say watarrrrr!

I was following a pick-up truck in a southern state several years ago. There were two kids riding in the back; probably brother and sister around 10 or 11 years old. I was shocked when the little boy pulled a plug of tobacco out of his back pocked and bit off a big chunk. Then I was really shocked when the little girl pulled out her's and bit of a big chunk too. :oldsurprised:

I cringe when I see someone texting or looking at the phone while crossing the street against a red light. Yet again
someone almost getting killed. I imagine the inner thoughts: "hmmm...read the text 30 seconds ahead , or be run over
by a car...hmmm... let me think".

True, and I think there is an additional/parallel issue of self-centeredness/selfishness: " I am too busy checking my texts, let others pay attention instead , and I won't be bothered".

Especially fun are the ones who cross the center line and drive head-on at oncoming traffic with that attitude.

Why do people use reserved words so carelessly? Likelihood used in its everyday sense when talking about probability, ditto for Force when talking about Physics, function in Mathematics, etc. Are you using your words in an informal or in a technical sense? Please choose one, specify which one and then stick to it.

The misuse of 'odds' is probably worse in everyday conversation. People who bet know the difference but an awful lot don't.

Function can be tricky given overloading between math and programming. Reminds me -- a friend recently interviewed a candidate who was 'an experienced programmer'. He asked the candidate: What is a function? Blank Stare. (Maybe that is an informal take on a function?)

That Oswald guy could probably give people pointers on this matter

Kind of scary the high percentage of programming interviews that leave interviewees stumped, like a deer staring at headlights. 4+ years of writing programs down the drain.

Non formal languages as used by people are highly context sensitive. Not really a new information.

I think it should help to remember that excellent comeback from Guybrush Threepwood -- "I'm Shaking. I'm Shaking."

No, the problem is when they go back and forth between Formal and Non-Formal ones without caring to indicate which one they are using.

I like these seemingly meaningful phrases that don't really mean anything : " That's like opening a checking account in the West Bank!". They are tricky because if you overdo it , it is clear you are speaking nonsense, and if you under do it they clearly have no meaning, so you have to straddle that narrow gray area.

You mean like me saying "I try to drive smoothly"? What I mean is ##C^\infty## but I doubt I'd be understood. At least nobody ever mentioned that it's impossible.

You can't overdo DADA. I love Dadaism.

(Mops = pug, but be careful with the plural: xxx. This is really highly context sensitive. As long as there aren't several pugs around, you better don't use it.)
