@freemo I would probably get cold quickly but the idea of weightlessness is interesting.

@freemo "it's easy if you try"

@freemo https://en.wikipedia.org/wiki/Stack_(abstract_data_type) i.e. it's weird to call something else a stack.

@freemo like for mushrooms, only the dry weight is reliable!

@freemo is this a freemason bootcamp thing? 😅

@freemo yes, but not really considering that panels could easily be cut into shapes other than rectangles. Even ovals are relatively rare. Original shapes tend to be distracting and get reclassified into "wall art between painting and sculpture".

@freemo for practical reasons, I reluctantly settled on foot/inch-based formats for my paintings: 18:24 and 24:36 (inches:inches). It doubles the surface area but doesn't preserve the aspect ratio (3:4 vs. 2:3). It's not too bad because if I double the surface area again, I'm back to 36:48 = 3:4. So instead of being always 1/sqrt(2), it alternates between 3:4 and 2:3.

It matters to me when dividing a 4 ft by 8 ft plywood panel without wasting too much.

@freemo I knew about the height:width ratio being constant at sqrt(2) but didn't know about the surface area considerations.

@freemo @dlakelan is there a simple, mechanical definition of a paradox? (looking for something more precise than "a reasoning mistake")

@freemo
@dlakelan mentions "saliency bias". I have to digest all this stuff. My overall impression is that different paradoxes emerge from the way we model things (and go beyond their domain of applicability).

@freemo i.e. not something I need for urgent or professional purposes 🙂

@freemo the original example was a "clever" post by a shitposting page on Facebook, something like this:

"It's not possible that every time we call your customer service you're experiencing a higher amount of calls than usual".

@freemo I skimmed the Wikipedia article about representativeness heuristic. Seems to connect to the notion I had of stereotypes vs. averages.

If half of an airline's flights are full and half are empty, passengers will complain that the flights are full every time, contrasting with the assessment of the crew who report that half of the flights are empty. How do you call this effect/paradox? (I forgot)

The same effect explains that if you have an average number of friends (= popularity), more than half of your friends are more popular than you.

Or when your doctor tells you you're in average physical condition but each time you go cycling, most cyclists you come across are faster than you (because the fast cyclists are also the ones who spend the most time on the roads and are encountered disproportionately).

@freemo yes, thanks a lot!

@freemo yes, thank a lot!

@freemo no, I didn't get the connection with regression to the mean.
