SUMMARY

The forum discussion revolves around the latest installment of the "Random Thoughts" thread on Physics Forums, highlighting various topics including critiques of documentary programming on the History Channel and National Geographic's recent ownership change. Participants express concerns about the quality of content in documentaries and share personal anecdotes, such as a humorous incident involving a clogged kitchen extractor fan. The conversation also touches on mathematical discussions regarding prime numbers and cultural observations about societal norms and language use.

PREREQUISITES
  • Familiarity with documentary programming and its impact on public knowledge.
  • Basic understanding of prime numbers and mathematical proofs.
  • Awareness of cultural commentary and societal norms.
  • Knowledge of language variations and their implications in communication.
NEXT STEPS
  • Explore the impact of media ownership on documentary content quality.
  • Research advanced mathematical concepts related to prime numbers.
  • Investigate cultural differences in language use and societal expectations.
  • Learn about the effects of solar irradiation in different geographical locations.
USEFUL FOR

This discussion is beneficial for media analysts, educators in mathematics, cultural commentators, and anyone interested in the intersection of media, society, and education.

One of my favorites: For n>2 , every number 1 less than a square is composite:

##n^2 -1 =(n+1)(n-1) ##. You get the actual factorization for free.

Example: ##899=900-1 =(30+1)(30-1)=31 *29##

[...] TV quiz show called Countdown [...]
I love the "8 out of 10 cats" version of that show. At first I thought Rachel Riley must be getting fed the formulas via an ear piece, but gradually realized she is a genuine arithmetic savant -- proving once again that life is deeply unfair, since she is also drop-dead good looking.

(Jon Richardson is also pretty incredible in the word part of the game). After I'd watched several episodes of the show I became pretty depressed at how crap I am... :oldfrown:

The Australia version "Celebrity Letters and Numbers" features Lily Serna in Rachel's role. She's also a LOT quicker than me at finding difficult formulas mentally.

My doc wants to staple an afterbirth onto my eye.
The attachment method is different but, here in the US after a chemical burn damages the cornea an afterbirth (placenta) is applied to promote smooth healing and improve vision somewhat during healing.

No mechanical attachment is needed. It is like applying a very thin plastic film to wet glass, it stays put.

Cheers,
Tom

There's a clip on YouTube where somebody (Lee Mack, I think) asked her "how she got like that" when she was kicking herself for solving a problem one way and only noticing afterwards that she could construct it in a more elegant way. She just said she's done it a lot. And if you think about it, the regular Countdown is on five days a week and she's been co-hosting for years now, which is a lot of repetition just on screen. Practice makes perfect, I guess.

No doubt she was too polite to reply "Because I wasn't born as thick-headed as you."

I guess she (and Suzie Dent) must be getting quite a good salary to put up with the frequent crap they cop from Jimmy Carr.

Thank you! And thanks for the welcome from @WWGD and @Borg as well. It's been a good while but I'm glad to see you're doing well.

I looked at your last post. It was 6 years ago. Going to hang out for a while?

I'll try for six years presence to make up for six years absence, how's that sound? :wink:

I'm with fresh on this one. What is the specific issue? If there is a problem you would use the Report link, no?

Bystander said:

Yes, when I first saw it I almost moved it to Intro, but left it there for the time being. It will probably end up getting moved to Intro, modulo your response to fresh and me asking for clarification.

In German, our confustion with your post would be "No comprendo". Oh wait...

Dang Kansas heat. It's only 92 degrees F, but the humidity makes it feel like 110 degrees F. :oldcry:

On our left, lives concrete-loving family. They have a pavilion with a fixed grill: two garage: two cars: most of the area is buried in concrete.
On our right living an older garden-loving (kind of...) woman. Everything in order: not a piece of weed, hoed twice a week.

We are poor (kind of...). We have no cars, no award-winning garden - we have only our jungle: with birds, bats, stag beetles and fireflies :smile:
We just spent half a bottle of good wine watching the nighttime show o0)

My coffe has just exploded inside the microwave! :D
The interesting point is, i have heated it and let it rest inside the microwave for about 2 minutes (after the heating has ended), and so it explodes! Could i finally have achieved the superheating state of coffe?

Having tried teaching myself theoretical mathematics several times, it's simply not feasible without a teacher. The definitions themselves are hard to understand, let alone applying them.

Some here seem to be teaching themselves, with other members as teachers. But, true, having someone to teach you in person would be better.

This depends on so many things, esp. the subject.

Perhaps if you gave the guys some more information?
What level are you at? Get to at school?
Maths is a big subject, which area are you interested in?

Theoretical statistics, undergraduate chemistry. Pretty solid grasp on applied maths, but my rigor is non-existent.
