#what is mathematics really

[mumblesplash]

something that’s been bugging me all day: how would you teach perspective drawing in a society that existed entirely within, say, a varied-gravity spaceship? so much of how we understand perspective is based on the existence of the horizon and our relationship to it. what if there’s no horizon? vanishing points as a concept depend on having a ground to be parallel or perpendicular to.

Y'ALL I FOUND A BIGGER LOT😭 🙌

I think this looks way better tbh. I'm going to say the first one was a trial build. lol

[earolinc]

how do i adequately express my love for math for an admissions essay. "talk about a stem subject that excites you" how do i put that this is my art and the most beautiful thing in the world and fills me with such a sense of enchantment that i feel as though my breath has been taken away into less than 750 words and make it cohesive

Surprising absolutely noone except undergraduate math students, it turns out math actually is only about numbers in the end!

[wheucto]

noticed these sorts of characters. decided why not make a diagram or whatever

transcript and more below cut

NORMAL OBJECT

An object, typically real or tangible.

Stick limbs and oval eyes.

Other than object-related abilities, no powers.

TRUE ALGEBRALIEN

Number or symbol

usually a surreal and bizarre entity

has supernatural abilities

more fleshy ??? arms; circle eyes w/ pupils

ALGEBRALIEN-STYLE OBJECTS

Resembles objects

Shares same traits with algebraliens otherwise

NONOBJECT

Not an object

May have powers

Could literally be anything

as a note, i say things more generally.

something i didn't put in nonobject but could have been put there is that they don't usually have faces nor limbs. though, they can definitely have limbs. nonobjects could be just about anything, as long as they aren't objects... like, a regular human for example. those notably have faces and limbs.

nonobjects do, by definition, include algebralien but i don't think it's very useful to talk about them as a group including algebraliens. unless like, apart from objects.

what counts as an "object" might be vague, especially dealing with more abstract things. for example, take a scribble. is that an object? it might depend more on show or interpretation. does Black Hole from BFDI count as a nonobject? maybe, maybe not.

also, there are algebralien-style nonobjects. which have the algebralien style, but are not objects. for example, a human or a turkey.

i'm a very don't tolerate bullshit kind of person and I respect and expect it so much when other people are real and straight up with me anyways whatever I say stems from my own thoughts and I cannot lie to you and tell you to do something I think is stupid if you ask for advice. anyways an acquaintance of mine who majored in English unless you want to work in primary school for a pay of barely 700 dollars complained how her parents want her to get a masters degree and she's thinking about getting one in marketing or something similar and then later on spreading into tech saying how she can work as a data analyst and I literally almost laughed out loud like it's absolutely insane how little university life prepares us for the future and how absolutely useless it is that you have university graduates here thinking they can work a job that requires a degree in either IT or economy as someone who read and talked about books for grades like please be so serious right now. I'm not upset with her for thinking this is possible just the general society for letting these young people down by telling them every career option is valid and it doesn't really matter what you study in university because it does

Pecco and Pedro are probably the people who more than anyone else want to beat Marc. Pecco because he is forced to do it for a matter of survival, his bet next year is to be able to win against Marc with the same bike. Pedro wants to win the first world championship with Marc in MotoGP, even better if he wins it against him, because of course that’s what he wants. I MotoGP your teammate is your first enemy, as surreal as it is, it would be more likely to see Pecco and Pedro helping each other (which would be unlikely anyway because they aren’t the type of people who do that) than one of them helping their teammate , especially if it's Marc. If anything Marc and Pecco have to be intelligent enough to at least not take each other out Portimao style, because in that case there will be someone behind them ready to bite

so I'm going to jump in right away by saying, I know this ask acknowledges it's unlikely but, yeah, pedro and pecco will not be helping each other in any meaningful sense - because they are both serious challengers to each other and they know it. sometimes, riders can be known to help non-team members in fairly small low-key ways (see in this post valentino accusing marc of deliberately towing ducati riders to get them ahead of his actual rivals in brno 2014). for both pecco and pedro, marc is definitely the bigger focus, but they are both perfectly aware of the danger the other poses, and will not be inclined to treat each other as anything other than an active threat

that being said! of course pecco has already nicely demonstrated this season that he does approach his marc fights differently than he does those with other riders (which is broadly the correct and smart thing to do, even if the specifics can be critiqued). portimao even gave us the direct comparison between pecco/pedro and pecco/marc! part of it, yes, will just be an element of self-preservation - marc is now back to being a major roadblock for winning any future championships, and he'll be in pecco's house so will of course require... extra attention. apart from that, it absolutely would be the most meaningful way pecco could win a championship, by beating the famous marc marquez on equal machinery... nobody has done that before, and it would instantly dispel any remaining doubts about pecco's ability and cement his legacy as one of the greats of the sport. he wants to beat marc so badly because marc is one of the two riders he's always been chasing... and marc's absence has left all the young pretenders in this odd place where they've taken the crown but don't quite believe it's theirs yet. (just to say this again, I personally don't share the view that marc's absence diminishes those titles in any way, but it is of course interesting when the riders themselves have these insecurities.) there was that interview from early-ish last year where pecco talked about some of his personal limitations and how he views his own status in the sport:

fascinating, isn't it? of course, I'm sure a second title will have helped to some extent in making him feel a little more entitled to that status in the sport - but this is not the kind of thing valentino or casey or jorge or marc ever would have said. there's a self-consciousness to pecco, an awareness of his uncertain, shaky journey to the top of the sport, how he's fully cognisant of how different he is to those names... which can be a problem at times - delusion is an athlete's life blood, and while the level headed insight pecco expresses here is arguably admirable, it is not necessarily helpful for him as a champion. on the other hand, sometimes lacking a little in the delusion department can be a good thing if it allows you to deliberately improve yourself, pushed on by the knowledge that you still have a long way to go... pecco's biggest self-inflicted wounds have tended to come when he's at his most comfortable - you can theorise about why this happens, but maybe that striver mindset is exactly what he needs to keep him going. it's still quite the admission to describe his 2022 season as more incomplete than either valentino or marc's title runs. (mind you, it's arguably even less complete a season than some of their misses - of course with valentino you have the obvious ones, but did you know that marc scored an average of 13.44 points in 2015 vs pecco's average of 13.25 in 2022? obvious caveat that in 2015 there were considerably fewer competitive bikes and barely any capable of regularly challenging for race wins.) the need to prove himself is always there with pecco... it keeps peaking through with him, and it absolutely peaks through in his approach to marc. yes, yes, acosta is the future, jorge martin has been his title rival more recently... but of course, beating marc would be special. do you think pecco ever dreamed that of it? do you think he really believed that he could before he was already premier class champion? with most champions, you would say it's likely. with pecco, I'm not quite so sure

as for pedro, yeah, obviously, that's just the cycle continuing lol. deeply curious what those two regularly competing at the sharp end of races looks like. pedro has kinda kept his distance, isn't that much of a marc fan himself... when he talks inspirations he tends to bring up schwantz, stoner, pedrosa, and of course rossi

schwantz is far from an unusual pick amongst riders, though as the years pass perhaps gradually more so - it certainly reveals an appreciation for the history of the sport. as do the other choices, in a way... let's not forget that acosta was eight years old when casey retired. of course back in the day casey and dani themselves got plenty of criticism for how 'boring' they were - that's just how these things go! nobody's ever nostalgic for the present etc etc

pedro did also talk last year about how the public wants celebrations and rivalries, critiquing how friendly riders are nowadays and saying people want battles like jorge/dani, valentino/marc, and so on (full clip here)

heartwarming: global number of people who still care about the valentino/sete rivalry is now confirmed at 2 (two)

obviously, you can't just go out and manufacture feuds because you're feeling like it, and pedro's had a pretty quiet rookie season in that sense. but once he feels like he's settled in and can challenge the infamous marc marquez in an actual title fight? on the basis of this rhetoric, you'd at least hope he's not going to be too shy in taking on the challenge. of course he too wants to beat marc more than anyone else... again, it's a question of legacy, how pedro clearly situates himself within the same lineage as both valentino and marc - even if personally he aspires to be more of a successor to the former than the latter. always better to take the crown for yourself, right? this is a kid who's clearly into the history of the sport and is already determined to make himself a big part of that story... weaving himself into that narrative by taking on a legend of the past, taking on the task of disposing with that legend himself. plus, given pedro is so aware of that history - he knows that what people remember are the rivalries. he wants some of that for himself! it'll be interesting to see how proactive he'll be in making that happen, certainly seems like an enterprising young lad

anyhow, yes, plenty of potential for both of those dynamics. and yes, they do very much want to beat marc - but if we're talking about who wants to beat him the most, jorge martin probably deserves a mention right around now. does have to be said that something dumb like the portimao thing is costing pecco and marc this year. it's kind of gone under given the sheer bucketloads of points all the title contenders are throwing away, but pecco would be eight not eighteen points behind in the standings if he had settled for sixth in portimao, and for marc it would be twenty four rather than thirty five points if he'd backed out of the move and had another go on the next lap. relatively unlikely to make a difference at the end of the season... though for mr title decider pecco bagnaia, it sure might be! I did joke about making the pecco/marc portimao thing tradition, but generally speaking two top riders crashing each other out isn't that common a thing, and it's pretty..? rare? that it's the same two riders on multiple occasions? I'm drawing a bit of a blank here, to be honest... then again, title contenders do seem to crash rather more than they used to (admittedly they also have a lot of opportunities now) - so maybe this is going to become a more regular occurrence. but what is more likely to happen is that when you have two competitive riders on the same bike, they do run the risk of taking turns stealing points from each other at the circuits where their bike is at its best. I think pecco and marc can probably minimise this given what a good all-round bike the ducati is across a range of different circuits, and also given that as individual riders they do at least seem to be reasonably distinct in what their strongest and weakest tracks are. all in all, I kind of doubt they'll cost each other like that next year... though admittedly if portimao is anything to go by I may be tempting fate

interesting thing about multiples of nine

i want to start all of this by saying i do not know many math terms. this was just something i found out for fun and would love to share it with random internet people. are line breaks affective?

first is something classic: multiples of nine climb down in the ones position and up in the tens positions.

one thing i found interesting was nine times the numbers one through ten. the digits that make up the answer can be added to be nine.

ex: 9x8=72 7+2=9

this applies all the way to 10 but when we get to 11 something interesting happens. 11x9=99 just looking at that you can tell that it does not equal 9, but 18 which is 9x2, but 9x12=108 which does equal 9

which got me curious on which numbers does this apply to so i looked at every multiples of nine (out of whole numbers) up to 50 and came away with this.

whatever digit is in the tens place or less will be the one where it would be 18. (i am so sorry that i dont know the terms)

ex: 33x9=297 2+9+7= 18 //// 34x9=306 3+0+6=9

so basically 89 is the last factor that you can multiply by nine and still have the answer be added to nine. (besides 9 times a multiple of ten)

so 89x9=801 anything below 801 can be added together to see if it is divisible by nine and still get a whole number.

i am going to ask google to give me five numbers between 90-801 to see if this actually works.

first:194 1+9+4=14 not a whole number when divisible by nine

answer;194/9=21.56

second;306 6+3=9 yes divisible by 9 and the digit in the ones place of the answer is more than the tens

answer;306/9= 34

third:569 5+6+9=20 not a whole number when divisible by nine

answer;569/9=63.2

forth;330 3+3=6 not a whole number when divisible by nine

answer;330/9=36.67

fifth;378 3+7+8=18 yes divisible by 9 and the digit in the one's place is either less or the same as the one in the tens

answer:378/9=42

So it does work! I tried to do even bigger numbers past 801, but couldn't find a pattern there. There might be one, but I'm not sure yet.

congrats on a random fact about nine. it's not even my favorite number or that i like math... i just dont want to do my lit hw... and had a huge headache during class

ok so im not sure that this is articulate for ppl who aren't calendarheads like me but the jewish and islamic calendars are both calendars in which a year is 12 lunar cycles, and the difference is that the jewish calendar has leap months whereas the islamic calendar does not. so every 2/3 years, the jewish calendar actually has 13 months, and so each time there's a leap month, the jewish and islamic months become out-of-sync by one month. the jewish leap months are timed so that the calendar is in accordance with the metonic cycle (the way that the lunar and solar cycles always align in the same way they did 19 years previously). which is to say, since the jewish calendar was standardized, there have been cycles of 19 years wherein there is a leap month during the 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years (sidenote—you can find what year we are in the cycle by dividing the jewish year by 19 and taking the remainder. for example, this year is 5783, and 5783/19=304r7, so it's the 7th year in the cycle, and not a leap year). but last year was the 6th year in the cycle—it was a leap year. so, it shifted the jewish calendar wrt the islamic calendar, and it put the month nissan (the month in which passover is celebrated) in alignment with the month of ramadan. this year, ramadan and nissan will stay in alignment. and next year, the 8th year in the cycle, ramadan will be in alignment with the leap month itself, which is inserted before nissan. so, it'll take 12 more jewish leap years before nissan and ramadan co-occur (if you look closely, you'll notice that it takes 33 years for 12 jewish leap years to occur, and you might recognize 33 as the number of years it takes for the islamic calendar to fully cycle around the gregorian calendar. which, of course, is not a coincidence!). as you can see, most of the gaps between leap years are 3 years long, but at the current part of the cycle, it's 2 years long. ANYWAY all this is to say that if it were a 3-year gap rn we'd be able to reuse that he is risen/he is not/he is off-limits until sunset meme for 3 years instead of just 2. sad.

why

just whyyy did they make Mycroft stupid in Enola Holmes??

"just because you don't have your brother's gifts" or whatever bitch i love sherlock but mycroft is THE genius in the Holmes family

like if one of the brothers is stupid compared to the other it's sherlock

i'm confused

Okay I have a math competition tomorrow and I need to wake up at 5 am, but a bunch of my friends are going roller skating tonight, which ends at 10 pm (22:00).

[ranger-danger]

Talking about stardew valley romances is so awkward. My friends are like “oh I love [every single guy, and Haley, but Alex]” and I have to go “oh I like Alex and Maru the most.”

[x-for-a-y]

so how are you faring after the gr2 results
