You can always tell a top tier awful chart/graph, where you legit struggle to figure out a worse way of showing what they're trying to. God tier are the ones where have literally no idea what they were even trying to show or what even a single part of them means. Bonus points if it has titles and excessive labels and they all just make things worse

Topology and geometry is one of the major branches of math. It's a little bit newer than analysis and algebra so there aren't quite as many people working in the field as there are algebraists and analysts, but I'd ballpark it at about 10% of all research mathematicians. There's a vast literature on the subject, and basically any subject that touches on shape has connections, so you see applications in fields like motion planning for robots, data analysis, optimization of circuit layouts, theoretical physics, chemistry, the analysis of voting systems, and a bunch of others that I'm not familiar with.

scientists are bad at naming things, then insist that their new names are the 'correct' ones. See also botanists calling the apple, the most platonic-ideal fruit in existence, a 'false fruit'.

Scientists just like to rigorously define things to the extent that eventually those definitions exclude the original examples. Like how Stonehenge is not a henge despite it being the thing that the word "henge" was derived from.

dirby posted:One of the seven Millenium Prize problems (the only solved one) was the Poincaré conjecture, and that was basically a topology problem (though a lot of geometry was used to solve it). Many people have recieved the Fields Medal for topology. I don't know your math background, so I'll just say you can get a sense of the scope of things at the wikipedia page for Algebraic Topology. unfortunately i have no money, but thank you for the information (and everyone else too)!

Tunicate posted:scientists are bad at naming things, then insist that their new names are the 'correct' ones. There’s a genus Acacia. “The” acacia tree is not in it. It used to be, but then hundreds of species from Australia and surrounding islands were added to the genus and. Lol whoops careful study reveals that Acacia is actually five genera wearing a trench coat. I’ll let Wikipedia summarize the rest, because it is a mess. quote:By 2005, taxonomists had decided that Acacia sensu lato should be split into at least five separate genera. The ICN dictated that under these circumstances, the name of Acacia should remain with the original type, which was Acacia nilotica.[1] However, that year the General Committee of the IBC decided that Acacia should be given a new type (Acacia verticillatum) so that the ~920 species of Australian acacias would not need to be renamed Racosperma. This decision was opposed by 54.9% or 247 representatives at its 2005 congress, while 45.1% or 203 votes were cast in favor. However, since a 60% vote was required to override the committee, the decision was carried, and a nom. cons. propositum was listed in Appendix III (p. 286).[8][9] The 2011 congress voted 373 to 172 to uphold the 2005 decision, which means that the name Acacia and a new type follow the majority of the species in Acacia sensu lato, rather than this genus.[10] However, some members of the botanical community remain unconvinced,[11] and the use of Acacia in the scientific literature continues to exceed the use of the new generic names. It’s basically botany’s equivalent to “Pluto is a planet”.

Platystemon posted:There’s a genus Acacia. Acacia friggen sucks rear end. Every time we got a job in the mid west I'd groan and prepare myself for an eternity of trying to classify woodland made up of almost a dozen interbreeding members of the Acacia aneura tribe: Acacia aneura, Acacia paraneura, Acacia aneura var. argentea, Acacia aneura var. intermedia etc etc A. intermedia is funny because it means something like 'intermediate between two other taxon' but they all hybridize and mutate anyway. Every few years someone with too much time on their hands will try and reclassify, lump or split up the aneuras for no real benefit to anyone. Sometimes we'd just say 'Woodland of mixed Acacia aneura aff. spp?.' because gently caress all that noise.

Eh there's still tons of stuff that's not utf-8, particularly for Chinese, Japanese, and Korean text, because the unicode standards around those 3 radically different alphabets are hosed. No English native monoglots question utf-8, sure, but that's a different thing entirely.

ikanreed posted:No one today questions usb-c To an extent, that's true. The AC adapter situation is vastly better now than it was ten or fifteen years ago. But lots and lots of devices in the world still use power adapters that aren't any flavor of USB. For example, in my sight right now are a set of desktop speakers, a wi-fi router, a AA-cell rechargeable battery charger, and even an Intel NUC mini-PC. None of these are terribly old and none of them are powered by USB. The battery charger uses some godawful proprietary cable that looks a lot like an old PS/2 keyboard plug, and the rest use various sizes of barrel plug. I would not dare to swap power adapters between two devices, even if the barrels happened to be the same size, without first carefully comparing the voltages listed in the tiny print.

USB C is literally mandated by the EU nowadays, and since it's a pretty big market, that's gonna have an impact. Especially since the benefit to the competitors are pretty negligible. Even so, Apple insists on lightning, to the point that they're trying to weasel or by making the other end of the cable USB C instead of the actual charge port of the phone.

Geology rules because we named poo poo whatever dumb name we wanted. Location? Sure. Name? Why not. Latin? Greek? Yeah. It sucks too because idiots keep giving new minerals names like firstnamelastname-ite which sounds terrible even if it's someone you like. And a lot of minerals end up with umlauts and alternate spellings thanks to inconsistent international standards. Also we made the same Acacia mistake a few times, like which mineral we called 'turquoise' which the vast majority of the gem turquoise is actually made of a different mineral (planerite). Also the IMA decided to rename musgravite to the incomprehensible magnesiotaaffeite-6N’3S and their conventions aren't getting any better or less opaque. Actually you know what geology sucks and we're bad at everything.
