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.

Sorry to hear, DL. Good luck for their recovery.

I've noticed that too. I figured it was because I was watching channels with high subscriber counts. It's not as bad on lesser channels, afaict.

In songs, adds ( seemingly) absurdly are shown some 5 seconds after/before the beginning/ end of the song.

I assume security settings in my pc were randomly changed; now I log back on, but I have to do it for each tab having the same app. So, e.g., if I'm reading different tabs here in pf, I must log on to pf separately for each tab. Good thing several forums available where others have posted same question.

Since the "logged in" condition is saved as a cookie on your machine, try doing a screen refresh on those tabs after logging in.

Cheers,
Tom

I really enjoyed it today. A cup of coffee. Hot coffee. Just coffee. No latte, no cappuccino, no artificial flavors, nothing. The only question was: with a cover or not? Milk and sugar were available as much as I liked. But that was all extras. And it was all that was needed.

And, yes, nobody asked my name.

Sort of goes with this offer by YouTube: White noise for studying, reading ,
if you're in a somewhat noisy place. I remember Toffler's prescient observation on how society would need to cut down on overstimulation.

As for me, I just asked for my Pepsi. All I wanted was a Pepsi. Just a Pepsi...

What to do when a person firmly believes the following are equivalent?
  1. ##\forall x \exists y P(x,y)##
  2. ##\exists x_0 \forall y P(x_0,y)##
and it's driving you nuts. Could ignore and let someone else deal with their malfunctioning mind. Am I responsible for letting it get there, though?

Every person is someone's father does not imply there is a specific person who's everyone's father.
Not even for Luke.

Edit: Will they accept a Universe/Possible World in which their argument does not hold:

##\{ x_1, x_2, x_3 \} ; P(x_3, x_3),P(x_1, x_2), P( x_2, x_3) ##?

Learning something new every day.

Wife out in the blackberry/blueberry patch pulling weeds. She had noticed a chipmunk in one of the blueberry bushes, so she went out to put down some rubber snakes (we'll see if they work). She started pulling weeds, so I went out to join her. She had several kinds in her hand and made a comment the weeds were out of control.

I reached down and asked about a weed I didn't recognize.

Me: You want to get rid of this?

Wife: Yeah, it's invasive. (I thought she said evasive).

Me: (pulling weed) What is it?

Wife: It's black medic.

Me: (Still pulling he weed)

Wife: It's poisonous.

Me: Thanks for letting me know. Is it poisonous to touch? (I'm thinking like poison ivy or giant hogweed).

Wife: No, just the berries (which the plant had).

I tossed the weed in the garbage and washed my hands. Not sure about its toxicity after reading about it.

I don't think it (medicago lupulina) is poisonous. Invasive in America, yes. It grows everywhere in Eurasia and is used as food for cattle. You won't do that if it was poisonous.

After reading up on it, I agree that it does not appear to be poisonous. It is a just another nuisance.

Heracleum mantegazzianum (giant hogweed / Riesen-Bärenklau) is our common enemy.

Source of taxol (an anticancer drug). Better know as yew trees to me.
We had them in our yard as ornamentals, when I was a kid. I was aware they were poisonous nature (I never ate any of their cute red "berries"!).

Here a really weird plant I read about recently:
Screen Shot 2022-07-06 at 2.06.26 PM.png

A kind of pitcher plant, in Indonesia, that grows its pitchers underground and catch most invertebrates there. Pitcher plants trap and digest animals to supplement their nutrients in a nutrient poor environment. They make a pot (pitcher) of digestive juices to digest trapped insects. Nutrients freed by digestion are absorbed through the walls of the pitcher.
This CNN report has some video.
Here is the original research report.

The berries aren't poisonous, only the seeds. At least the European variant. The needles and the bark are. And 100g needles isn't very much. My favorite syrupe against cough is made of needles. Or was it pinecones?

A Lottery Lawyer Won Their Trust, Then Lost Their Mega Millions
https://www.bloomberg.com/news/feat...inners-lost-riches-after-using-lottery-lawyer
Jay Kurland built a practice giving legal and financial advice to jackpot winners. He’s now accused of fraud.
In 2018 he started representing the biggest solo lottery winner of all time, a woman who’d bought a $1.5 billion ticket at a convenience store in South Carolina.
I wondered what happened to that anonymous woman who won the $1.5 billion (probably about $950 million after taxes).

The spies recommended dumping the android and going with the "dark side", yup, iphone. I don't miss the glitchy android one bit and comparing play store and apple store apps for malware is a little sobering. (spy vs. spy was my favorite strip from mad, thus the avatar.)
