There's no such thing as useless knowledge. I keep finding actual practical uses for all kinds of trivia I've picked up over the last twenty years, and while it does surprise me every time, it certainly encourages me to keep accumulating it.
@chao Fun fact: deciduous trees evolved in the higher latitudes where shedding their leaves in winter gave them an advantage over evergreens, since they could then have big leaves that didn't need to survive winter. These trees then slowly started spreading back south until they more or less replaced the evergreens in the equatorial rainforests. They still shed their leaves, but because there's no winter there, they do it ALL THE TIME.
@chao This constant deposition of leaves keeps the soil there very fertile, but it's naturally of fairly poor quality without it, as farmers find to their detriment when they clear rainforest hoping for good arable farmland. So they have to keep clearing to get new areas of fertile soil so they can grow enough food to live. This is a significant cause of rainforest depletion, though less significant than logging.
@chao Expressed in terms of formal logic, it'd be learning ⇒ awesome, learning implies awesomeness. For true equivalence, it would also have to be true that awesome ⇒ learning, and not all awesomeness involves learning (∃awesome : ¬learning — there exists an awesome thing which is not learning). And now you're learning about set and logic notation!
hmm. the best way to consider the awesomeness of something would probably treat it as an n-dimensional set of results where each possible factor has a corresponding coefficient in their dimension
eg [learning, 1] ∈ awesome and [learning, 2] ∈ educational
so in the 2-plane of awesome-educational, learning is a vector of (1, 2)
and then you can add vectors of different factors to evaluate the outcome
awesome analysis :D Show more
if we assume that every dimension of this is equivalent to a real number line and everything maintains relative size*, then we can determine if something appears to be a minimal dimension, too!
because if this doesn't work, clearly it's composed of multiple smaller dimensions! :D
*(eg it's well-ordered and the like, so things don't change just because you compare it to different things)
awesome analysis :D, cats Show more
if one cat has cuteness 1, and another has cuteness 2, and a third is cuter than the second, but you determine the first is cuter than the third
then you can be sure that cuteness as actually made up of smaller dimensions! like behavioural cuteness and aesthetic cuteness, for example!
this is also a good way of rating music and games, I suspect! :D
@Terrana if only this were true for music. I'd love to know the benefit of knowing, off the top of my head, that Michael O'Martian did piano on Steely Dan's Aja song. OK, sure, there was a plethora of amazing talent on that recording session, but I fail to find any sort of 'practical' use for it. It probably wouldn't even come up in a trivia contest! :( https://en.wikipedia.org/wiki/Aja_(song)#Personnel
