Discussion Overview

The thread discusses various random thoughts and observations, touching on topics such as media programming, personal anecdotes, language use, and mathematical curiosities. The scope includes informal commentary, humor, and reflections on everyday experiences.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express frustration with the quality of documentaries on channels like the History Channel and National Geographic, suggesting a decline in factual programming.
  • There is a humorous anecdote about discovering a polythene bag obstructing a kitchen extractor fan, leading to a discussion about the clarity of installation manuals.
  • Participants share thoughts on the nature of prime numbers, particularly regarding the status of the number 2 and its implications for mathematical proofs.
  • There are reflections on language use and the reactions to grammatical errors made by native speakers, with some participants sharing their personal responses to such situations.
  • One participant humorously suggests that if 2 were not considered prime, it would complicate the understanding of prime factors in even numbers.

Areas of Agreement / Disagreement

The discussion contains multiple competing views, particularly regarding the status of the number 2 as a prime and the quality of media programming. No consensus is reached on these topics.

Contextual Notes

Participants express varying degrees of skepticism and humor, with some comments reflecting personal experiences and subjective opinions rather than objective analysis.

Who May Find This Useful

Readers interested in informal discussions about media, language, and mathematics may find this thread engaging.

Anything which can be computed using recursion can be computed without recursion and visa versa. So the question boils down to asking wether all fractals are computable.

I don't know if the definition of a fractal is clear enough to answer. If we are talking about an instance of a fractal then yes, in a trivial way, you can multiply an uncomputable real number with each coordinate value.

Besides a trivial example like that, and if we factor out all of those kinds of non-essential factors like noise, I'm not sure. How about a fractal which switches between two rules periodically as it recurses, but uses an uncomputable sequence to determine if it will switch or not at the start of each period? Then it is morphing unredictably between different fractals. Is that a fractal?
But I am curious as to your claim that any recursive computation can also be accomplished without recursion. I'm aware of specific cases when this is true , but not of any result to this effect.

Linguistic pet peeve:
The phrase is “vice versa” from Latin with the meaning “the other way around”.

I can't understand advertisement of products these days anymore...
It is all about people dancing, singing, the advertisement ends and i have no idea what product they were trying to sell/talking about.

A good ad would be the other way around.

Laxatives? Tampons? Hernia Truss?

Maybe all in one? And an AM/FM radio and Swiss Army knife too.

A bizarre exchange:
Person 1" I went to the school of Hard Knocks"
Person 2 " Well, you flunked out of it"

Talk about stretching an analogy too far.

Probably a remote procedure call prior to going offline, this is only a theory but Magic is a long shot.

Dark magic: by some automatic settings it'll download the files beforehand and do the restarts outside 'active hours' on its own initiative, without asking anything.

Quite an annoyance when you have a ton of stuff left on on your desktop

It's weird how visual appeal can affect our enjoyment of something.

If you took your favorite food and put it on a plate to eat, it'd probably look wonderfully appetizing.

Yet, if you put it in your mouth to eat and start chewing (it tastes good at this point) and THEN take it back out and put it on the plate (the chewed up food with saliva and all), you probably would not want to eat that.

YET, IT'S THE SAME FOOD ITEM!

It's day 5 for me , of spending 20 consecutive minutes sitting down doing nothing.
What was the motivational phrase:
" Today's the first day of the end of your life"?

He sells his 5 castles, 4 Burmese Pythons, the 7 World's Tallest Dwarfs, his 18th century Iron Maidens, his DeLorean, and he may be ready to pay his debts.

I forgot the password I had set up 20 minutes prior, yet I was able to remember that the Earth weights ##5.977 \times 10^{24} kg##.

Hang in there, it's worth it. I stopped over ten years ago, still, sometimes... nope no way. It's nice to be able to breathe when you need to. 🚭

I have written a little App that tells me the day. It also tells me what I would throw away if I made an exception.
