Idk there's sometimes value in having quantities in decreasing order so you aren't changing measuring devices constantly and for the sake of minimizing clean up.

For me at least, I like to have everything out and ready to go. My wife writes her recipes as inline directions with NO separation and it's super annoying when you skim it and find "oh shit, I don't have any peanuts at all in the house."

The visualization is less about the ingredient quantities and more about the process I think. I DO find it annoying when you're using the same ingredient two or three times and they're is no giant, bold HEY DUMMY DONT PUT ALL THE FLOUR IN THE BOWL RESERVE SOME kind of message.

When I write a recipe for myself I do two columns, ingredients on the left and instructions on the right ordered by logical subsections like "peanut sauce", and "the roast". I put recipes on index cards, and also like you suggest, across the very top of the card I always write 3 things: 1. Name, 2. Total cooking surstion, and 3. Grill or oven temperature. So I guess we have more or less the same opinion in retrospect!

Cool. I love animals and I eat meat and I love it.

I see nothing wrong with it. Death is part of life.

Do you ever ask yourself why it is that you need other people to believe and practice what you believe? And do you find when other peole impose their beliefs on you find it offputting and upsetting?

If you classify tactful social behavior as "lies and bullshitting" it probably IS spectrum related.

but ASMR is generally just annoying/grating to me

It's so rare to find other people like this! ASMR sound effects make me viscerally uncomfortable, and I especially get creeped out by the whispering voices as if they were right next to your ear 😰

Add in a psychedelic experience or two, and it becomes impossible not to recognize how ridiculous it all is.

Can be done without them, of course, but psychedelics can blast you right to that position, for better or worse.

Not enjoying manipulative behaviours because of their wider negative implications on society is autistic? The Kool-Aid must taste real good.

I can somewhat relate with that. Eating meat is one of the few behaviours that I still do despite being unable to morally defend it. It's not even that I'm trying not to think about it or have to somehow deceive myself believing that it's good. I know exactly what I'm doing. The convenience of it simply outweighs the moral guilt.

What I think would possibly make me feel different about it is someone handing me a gun and telling me to shoot a cow. If it turns out that I can't do it, then that really puts into question the outsourcing of the messy part of it in the first place.

Thank you, much better put than myself.

Same lol. And the weird thing is that I quite enjoy number-based games like Picross and Hexcells, but I hate actual arithmetics.

I've taken the slow route and have been doing mindfulness meditation for a decade which probably plays a role in all this.

but other than that I never got why I shouldn't just jumble up pitches any way that sounds ok to me.

Well the beauty of music is that you can do exactly this and it's fine.

Pretty much all "music theory" is Western-dominated anyway and far from all-encompassing.

There was a really good YouTube video about this a few years back, by I think Adam Neely. Let me see if I can dig it up.

Edit: here's the link - "Music Theory and White Supremacy"

https://www.youtube.com/watch?v=Kr3quGh7pJA

Very good video.

My issue with language learning is that I hate illogical and inefficient systems, and sadly languages have so much organically accumulated bullshit in them, that I get too frustrated to continue 😅 (Yea I know, I should try Esperanto, but even that has genders.)

Like I said, if you are applying the term "manipulative behaviors" (or lies or bullshitting) to generally tactful social behavior, that is consistent with ASD. If you mean lying, deceit, and gaslighting in a malicious way, OP is probably around toxic people because I think EVERYONE would agree that it is awful.

Maybe you ought to make sure you understand people's positions before you lash out, yeah?

It's not a fraction. That's the first thing you gotta grok (yeah I'm still gonna use the word when it fits, fuck Elon).

Math and music are intimately related, but the time signature is not a fraction. It's just two different numbers separated by a line.

i’m a senior computer engineer currently specialising in signal processing algorithms on constrained systems

Ah. Hmmm. I mean, division is just multiplication turned on its head, so maybe it would help to start with how you visualise multiplication, and see whether you can extend that to work for division too? 🤷‍♀️

If it makes you feel any better, my arithmetic is horrendous. I understand complex mathematical concepts easily, but don't ask me to add 2 big numbers. It's ridiculous 😂

None of what's OP wrote was alluding to "generally tactful social behaviour".

Maybe you should learn to read before you get all defensive, yeah?

I struggle to write paragraphs covering most topics, even those I am familiar with. I can write a sentence 10 times over, before deleting it all together. My output is extremely jagged and frustrating. Finding the words to introduce ideas or to transition sentences is quite painful and slow.

My handwriting is also extremely laborious. I have to put a lot of time effort into making my writing “neat”, aka legible. Growing up, I was always the slowest kid copying down slides/notes in class.

Perhaps both of these are related to my ADHD, or perhaps I just need more practice lol. I have been making an effort these past few years and I’ve been seeing improvements.

Adding my personal favorite, 7/8 time. (My wife and I bonded on our second date because we share the same favorite time signature…we’re dorks.) I love it because our brains are expecting an even number of beats, and since it’s missing just a single eighth note when the next measure begins it almost feels like the song is falling forward or rushing.

You CAN count it sequentially, but it’s much easier to count like this:

1 2 1 2 1 2 3

or

1 2 3 1 2 1 2

Or if the composer was feeling spicy, both alternating back and forth.

Example 1: I Am The Doctor Song begins in 7/8 time, it begins quarter quarter quarter eighth if you want help counting it.

Example 2: Subdivisions by Rush I count this one as beginning in 7/8 time, quarter quarter dotted quarter, and I especially love it because it seamlessly transitions into 4/4 time at about 19 seconds in.

Oh, it does

Weird: in my multiple attempts to grok what time sigs are about, I've heard a different explanation: that the lower number indicates the beat on which the emphasis is. But now the first paragraph in Wikipedia's article body confirms what you say. Some kind of Mandela effect going on here. However, Wikipedia also notices that irrational meters may have a lower number that's not a power of two.

Yep. The bottom number is always divisible by 2

4/4 is the workhorse! The majority of music is in 4/4 time, nothing wrong with it at all.

Certain rhythms become really weird if you try to write them in 4/4, which is why other time signatures become useful. Just now I tried to “conduct” a waltz in 4/4 and quickly devolved into laughter.

you know cuisenaire rods? those counting stick things. i think in those. that means addition makes a line, multiplication makes a plane, exponentiation makes a cube. higher exponents make cubes of cubes.

division doesn't really fit in that visual because it's a quantised system. fractional multiplication fails for the same reason.

I can read and understand nuance. Nothing about what OP said indicates what he is talking about ISNT that either. If you think everyone is lying and manipulative you are either surrounded by toxic people, OR you don't understand social interactions. Everyone who is socially successful is not being a manipulative liar.

Autism spectrum disorder is a condition related to brain development that affects how people see others and socialize with them. This causes problems in communication and getting along with others socially

https://www.mayoclinic.org/diseases-conditions/autism-spectrum-disorder/symptoms-causes/syc-20352928

If you're having trouble seeing this, talk to your doctor. There is nothing wrong with playing by a different set of social rules unless you don't understand that you are.

Edit: Or maybe you're just an asshole. I can relate.

This is a really good explanation. I should tell my kid this to help him with masking. And it'll be great when he tells the teacher he's hungover.

Have you looked into spaced repetition / Anki for the memorization already?

I feel like that's not something I got a good grasp of until I started learning other languages. At that point I became really thankful for grammar rules.

It is a sport. You read the recipe and visualize yourself making it. All the while thinking about how to manage time. Repeat that several times before starting. Then prep everything Chops veggies, measure spices, get oven hot, boil water. Whatever. Just have all that going.

Yes but the default position should not automatically be "maybe you're on the spectrum".

Nice black OR white argument there. There are other possibilities such as the autism diagnosis being floated in everyday arguments to discredit people who see the uncomfortable truths with society and where that is leading us... Which was my point in fewer words.

You've even proven this hypothesis somewhat by suggesting I go see a doctor. Your immidate response to someone who disagreed with you was "might be autistic". All dressed up in nice placating words rather shorthand internet responses.

Perhaps neither of us are the true assholes...

many people are trying to explain time signature

I'm glad they did, because I also have a hard time with time sigs, and was hoping to see some explanations. In fact, one comment here finally elucidated that I understood signatures wrong this whole time.

The band took off in January with the KEXP performance, after playing shows for two years. Their outlandish garbs and wacky setup likely contributed to the popularity — wouldn't expect to see much interest in microtonal math-rock otherwise.

For most of my life I slept like a log for eight hours straight and basically never had dreams. Then recently-ish I botched my day routine beyond repair and discovered that I do dream when in light sleep, namely when falling asleep again after having woken up. Combined with drinking too much alcohol sometimes, this gives me shittiest completely absurd dreams of no value, just confusion and a very unpleasant feeling. Even when a dream is nice, I then wake up remembering I have my daily grind to look forward to. I'll much rather go back to no dreams.

It could be ADHD. It could also be anxiety disorder. I was a history major in college, so I had a ton of papers to write. My anxiety made if extremely difficult to write anything. Like you, I'd write it out, delete, rewrite, delete etc. It was awful. At the time, I would actually start drinking to the point of being slightly inebriated. I found I could actually write better at that point, because the alcohol shut down that anxiety (and if I am honest, it made me give less of a fuck about what my professors would think of my writing). Obviously, not a great solution, but it was good short term and I always got good grades on my papers. Now that I am better medicated for my anxiety, I imagine it wouldn't be so bad to write a paper now. Trouble is, my job really doesn't require me to write much lol.

Double Slit:

The word "measure" or "observe" carries a lot if confusion when people talk about the double slit experiment, as if it wasn't one of the most important aspects in physics.
Imagine that at first you're kicking a ball at a wall at random. Now you put a goalkeeper between you and the wall, he catches the ball and looks at it and then throws it at where he thinks it would have gone if he wouldn't have caught it. Those are two entirely different scenarios. Same thing goes for the double slit experiment. A non-measuring and measuring setup are completely different, it just seems like magic because you can jump between them with a flip of a switch.
At the atomic scale it is impossible to measure something without the probe interacting and altering the object you are measuring. Imagine if instead of weighing a car to get it's mass, your have to smash another car into it and calculate the mass from the impact energy. I know it dumb, but that's essentially the best we can do when it comes to particle physics.
Also in a world where cameras are omnipresent, we are used to take snapshots of reality. But that's now something you can simply do at atomic scale. You can't take a photograph of a photon mid air.
Additionally, imagine if I give you two sets of images of a car going along a road.
The first set shows it has travel fairly far between the first and second image taken. You also know the time that passed between the images. Now it is trivial to calculate the average velocity of the car. But if I ask you about the position of the car some time between the first and second image, the best you could do is guess, since you don't know whether the car might have speed up or slowed down during that time.
The second set of images shows the car at almost the same spot, the time between the images is also much much smaller. So small in fact that even the precision of your stopwatch starts to matter. Now you could count the pixel differences and still figure out how much the cat has moved and its average velocity, but it will be much less precise than the first set. But, if I where to ask you about the cars position between the images, you could tell me very precisely where the car was, since it's velocity couldn't fluctuate a lot in such a small time frame and distance. That's in essence the uncertainty principle, you either now the position or the velocity of a particle precisely. Of course you still can't take a snapshot of a particle. But to figure out the cars position you could also force it to stop briefly or put off-ramps along the road, and by checkout which one it took, you can figure out where it was at that point in time. This is essentially what we do with particles. We confine the particle in it's position/path to figure out whether it went through one slit or the other and therefore give it a defined trajectory through our method of measurement. That's really all the magic, you can't check without interacting and intercating changes the outcome at those scales.

Quantum Computing:
Before we had our normal bit based computer we had analog computers. First mechanical systems then electrical. They operated on either speeds, forces, positions, friction, etc for mechanical ones and voltages, currents and charges for electrical. Calculations hat to be represented with physical components, where each module was a calculation step. The good thing is, the calculation was essentially instantaneous, the bad thing was they were hard to manufacture, had to be calibrated and once setup for compute, they they were hard to alter. But when it comes to things like derivatives and integrals they are hard to beat. For example current is just the time derivative of the charge. So you if set up a computer to measure charge at the input and current the output, you can instantly calculate derivatives of very complicated formulae.

Then, along came Turing and showed that not only can numbers be represented as a binary number sytems, but also that addition, subtraction, multiplication and division operations can be executed through a series of not-and (NAND) operations on those binary numbers. This was good enough for 99% of our problems since we now had a component that was easy to manufacture en masse and almost every mathematical computation could be done to an acceptable level of precision given enough time. But one thing that classical computer suck at is randomness, since whole point of bit based computers was that you don't have to deal with random fluctuations in your electrical components like with analog computers. We don't want to measure 1 - 5 ± 0.1 Volts, we want a clear threshold for a 0 and a 1 for our systems to work reliably.
That's where quantum computers come in.
Their bits have an undefined state which can be resented mathematical and is especially useful in calculations where probability is involved. Then, just like with the double slit experiment you "measure" or interact with them to lock in their properties and get your result. Its hard to imagine but there are simply areas of mathematics where working with probabilistic states instead of numbers is necessary.
Think of it as 3 separate areas of mathematics:

Analog computing - > Algebra and Analysis
Bit based computing - > Discrete Mathematics
Quantum computing - > Stochastic and Crytograpy

Stochastic is generally a hard to understand topic, so quantum computing isn't far removed in comprehension. That's why quantum computers also won't replace classic bit based computing, since they do not do discrete mathematics any better, it's just that classic computers really are that much worse at probability calculations hence the claims how much faster quantum computing is (in those very specific areas)

People with ADHD don't even have the word "plan" in their vocabulary.

Reading your first couple of paragraphs I was going to ask if you have ADHD, because they're very relatable and I definitely attribute it largely to that. Practice and having a "system" for writing helps me a lot too

I never got why I shouldn't just jumble up pitches any way that sounds ok to me. Ultimately I decided that I'll spend my life composing music, deliberately ignoring harmony theory as material ...

Well, we have a word for jumbling them up however you feel like: jazz 🙃

Okay, more serious response, at the end of the day it is all about having it sound good. No one's going to question why you did things a certain way, if it sounds good.

I try to see it more as a shortcut for making things sound good. It's just a set of known-good strategies that you can apply, if you feel like it.
Like a tube with premixed color. Yes, you can mix your own color, and many times it is necessary to get it just right, but sometimes you just know that a few dots of khaki are what you want.

Just to chime in, I'd say I have very high propioception, but I have a hard time getting my head out of the way of my body. So I will do weird things like drop a spatula but catch it before it falls a foot because I'm thinking through the process of holding the spatula, and fumble it, but when it falls I'm just thinking "catch the spatula" and do it spectacularly. So I was also a clumsy child, and have the scars to prove it, but mostly because I was thinking about everything I was doing.

I basically don't have any friends of my own anymore. The ones from high school I was never really close enough with to hang out outside school. We were just too different. Almost a decade and a half later and we see each other maybe once a year and don't talk outside of that.

College was supposed to be a place to meet new people, and I did meet a few, one of which is my current partner. But that also didn't last past college years, really.

I'm now in a different country, don't really speak the language well enough and don't really have energy or time to find new people. Plus, my introversion, social anxiety and health are only making it harder. My partner occasionally comments on me having no friends of my own, but then I look at his friend circle and want to roll my eyes. Most of his friends are from high school years, and he sees them maybe once or twice a year. There are a few he met through work, but it's easier for him because the field we work in is male-dominated. So for him it's okay, for me it sucks to be the only woman. But he doesn't hang out with any of these people on regular basis. Realistically, most people he knows are acquaintances.

I think about this whole situation frequently and it makes me depressed and bitter. I feel like even if I find new friends, I'll never be the friend, you know? They'll always have other people they've been friends with for longer and I will be either not as important or discarded later. It's been this way my whole life. Always easily forgotten and replaced.

First, screw grammar, I've learned 3 languages without ever learning their grammar, including English.

Find a topic that you are very knowledgeable at in your native language and start consuming knowledge on that topic in the language you try to learn. Go back to the basics of that topic, something you know by heart. There will be a reversal where instead of listening to the language and trying to understand what is happening, you will already know what is happening and just listen to the words. You will go from "What did he/she say?" to "Oh, that's how you say it!". Its way easier to append connections in you brain that create new ones, so the familiarity of the topic is a stepping stone to learn the language. Of course you will still have to pause and translate constantly but it will be less and less necessary with time.

I had a similar experience until I read more books, specifically older books. Turns out when people had only written letters and books as the main media of communication, they wrote elegant prose. Who knew? lol

Also when struggling to find words to fill my paragraphs, I reached for connectives, and synonyms in a thesaurus. Without these, my paragraphs looked like a random assortment of sentences, repeating themselves to oblivion.

Getting up early or ever feeling rested. I don't think ive ever felt good in the morning. Basically, if I have 5 drinks and sleep, I'd feel identical waking up as if I'd had nothing. I also feel the same with 5 hours of sleep vs 10. No difference. And I do sleep its not insomnia, just doesnt work.

Division is taking a plane and breaking it into equal lines. I assume when you multiply you are already giving that plane bounds because anything else wouldn't give you a result. It takes a few passes to go the other way, but your facility with powers of two can help you narrow it down quickly enough. You're just trying to find out how long the box of a certain width has to be to fit a given number of blocks.

Maybe it helps, maybe it doesn't. It's surprising how many ways people have found to achieve the same goal.

That really bothered me at first! Kept thinking 'why ever have a different time sig? No need for 13/8 (or whatever) when you can just sprinkle in double dotted 16th notes tied to 8th note (or whatever).'

Over time I slowly realized that it's not about technically being able to write it, but rather describing what usually happens. (Tho I still don't really understand, intuit, or hear any of it well.)

Real friends are the ones that stick with you when shit hits the fan. When you're an adult and you meet new people, you usually want to show yourself from your best side and for everything to go well. She we were kids, shit hitting the fan was somebody kicking a ball into a neighbors window or falling of a bike, minor things as an adult, but as kids that built character. The stakes are so much higher as an adult when things go wrong, so generally you avoid it even though this means that most of your relationships are superficial.

I'm not saying that something horrible must happen in order to get friends as an adult. But sometimes it's better to simply work against the odds together to form a deeper connection.

Metallica's Nothing Else Matters is a walz and you can't convince me otherwise.

Hmm. I know the point of this thread wasn't supposed to be a bunch of strangers info-dumping your weaknesses at you, but I'd like to take a crack at this one 😉

Problem one may just be that you overestimate how much the rest of us "intuit" or "visualize" division. It may just be that the rest of us use the tool for its outcomes rather than because it feels right, as opposed to visualizing it. Maybe it's just the language you chose to use, and it doesn't imply what I said, but it does make me very curious how you visualize addition and subtraction 😛

Okay, that aside, division is the opposite of multiplication, that's the thing it does, but it's also how we reconstruct its algorithm. Pies and their slices are fine for fractions, but here we're talking about division. So instead I'm going to start with dealing cards. Each card will be a ©, and we'll start with 15 of them, and we have 4 players.

©©©©©©©©©©©©©©©

Okay, first round, we deal out the first 4, one to each player

© © © ©

©©©©©©©©©©©

We have 11 remaining. Next round:

© © © ©
© © © ©

©©©©©©©

2 to each player so far, 7 remain. Round 3!

© © © ©
© © © ©
© © © ©

©©©

3 to each player in 3 rounds, and we can't do another round because we have fewer than 4 remaining. Specifically 3. So we could now answer that 15 divided by 4 is "3 remainder 3", because that's how many we get per player when there are 4 players, and then there's 3 left over.

The reason I've constructed it this way is because we've reconstructed the primitive square intuition of multiplication, but from the other direction! I think we can see how 4×3 makes 12, and then also how we did the dividing by re-distributing the first 12 cards of our 15 into 4 columns to work out how many rows our square would have needed to be to get us to 12. We knew we were interested in 4 columns, that's our problem setup, but we didn't know how many rows that meant, so we divided them literally amongst the columns until we ran out. Then we looked at the square we'd built and said "aha, I guess it was 3 rows!"

To put it in algebra format and play around a little:

15 = 12 + 3
15 = 3×4 + 3
15 - 3 = 3×4
12 = 3×4
12 ÷ 4 = 3

Just playing with division being the opposite of multiplication. Maybe that didn't help, in which case ignore it and go back to the cards thing! 😅

Okay, so that's algorithm number 1, and it works every time. With integers... So what the heck is long division?

Well basically it's a heuristic algorithm on top of this attempt to make squares out of numbers, where we want to use our intuition about multiplication, because it's easier, in order to do division. And basically the only reason to do that is because dividing each number by getting a set of counting stones in that quantity and divvying out a square is time consuming and we're busy people.

So we're doing 15÷4. We bascially guess how many rows we think this will have, by our intuition about the 4s times-table. We go "okay, maybe 2? 4×2=8, 15-8=7, that's bigger than 4, so I underestimated, but not by much. So I try 3, and that gets us our 4×3+3 from before. If we'd started with a guess of 4, we'd have got 16 and known it was too high and come down to 3. It's about guessing how many rows our square would have if we divvyed things out like before, but hopefully without having to actually do that work. And we check that guess by calculating the remainder and making sure it's smaller than the number of columns in our square, because if it wasn't then we could go another row.

Okay, now what about long long division. Like 1573÷48?

Just like with long multiplication, we want to leverage our intuition about smaller numbers to break down bigger ones. So we're going to break down 1578 into 157×10+3. Then we divide 157 by 48. I don't know about you, but I'm not great at my 48 times tables, but 48 is near 50 and 157 is near 150, so I'm going to guess 3. 48×3 is 144, 157-144 is 13, so we did good. 157÷48=3R3, or 157=48×3+3. That's great! But it wasn't the problem we were ultimately trying to solve. 😛 So we need to put back what we took off before, meaning our running answer so far isn't 3, it's 30. And our remainer isn't 13, it's 133, because we broke 1578=157×10+3 before, so 13×10+3 is 133.

So now we have a smaller new problem! 133÷48. Again, I'm going to go on my "about 50" intuition from before and say 2. 2×48=96, 133-96=37. So far so good! So now we add our 2 to our answer of 30 so far and get 32, and our remainder is 37. And, in this case, we're done! So 1573÷48=32R37.

An interesting property of this process, is to check our work, you can long-multiply 48×32 and you'll notice some old friends. You'll do 2×48 and get 96, you'll do 3×48 and get 144 which due to position is actually 1440, and you'll add those together to get 1536. Then you can add 37 to that to get 1573!

And one last step here. By generalizing our division algorithm to be based on multiplication and subtraction, we can extend this process to non-integer numbers in a way that's difficult with our "card dividing" method. We can multiply and subtract non-integer numbers already, after all. And even more than that, if we want to get rid of our tidy remainders and replace them with dirty dirty decimal places, we can continue to extend this process infinitely! Instead of stopping at remainder 37 we can extend our question to 1573.0, convert our remainder to 370, and then ask how many times 48 goes into that, get 7R34, but remember it's not actually 7, it's 0.7, so our total so far is 32.7 and our remainder is not 34 but 3.4, and if we check we can see that 48×32.7+3.4 is in fact 1573.0!

And if we want to eliminate that remainder altogether we can just keep adding new zero deicmal places to the right, and keep working our remainder smaller and smaller until it's either perfectly zero, or we decide it's small enough that we're going to round it to zero from here. Or maybe we get repeating digits, which is a story for another time! 😉

So, I don't know if any of that helped at all! But I enjoyed typing it, so thanks for reading! Also, my "long division" section was done conversationally rather than in the typical "frame" that long division goes in. That's because I was explaining my thought process, but the frame is doing the same thing, it's basically just there to help you keep track of where you're at in the problem, which deicmal place everything is aligned to, etc. But it's not essential to the process! There's no magic, besides algebra I guess 😛

I made that suggestion with the express purpose of being a dick.

I didn't get that point from your earlier comments, they seemed equally flippant as the guy who straight up says "maybe you're autistic". I can absolutely agree that in one-off circumstances in forums like Lemmy there are people who dismiss arguments by people who are passionate about things by calling them autistic. At the same time, there is a whole group of people I grew up with who have come to ADHD or ASD diagnoses as adults (not to mention some inlaws) and whose lives are easier now that they know that some of their foibles have well known treatments or coping mechanisms.

I think if you dismiss a majority of people as generally manipulative or poorly intentioned, there's a fair argument there for introspection.

I guess I should apologize because I came here looking for a fight. I have to take an old friend to her very last vet appointment in an hour or so.

As the saying goes, "Draw with your eyes, not your brain." Drawing is just a loop of asking yourself whether it looks right or not. Nobody is timing you, if you have to check a reference a million times to draw a single line and then erase it angway then so be it, because the next line will maybe only take half as much, and then half of that...
Theres this wrongfull elitism that an artist has to be able to draw perfectly from memory. They don't. Fuck it. Print out an image and trace it, that practices line commitment, line width control and scale. Then you can use the traced image to practice shading and coloring. You don't put a kid on a bicycle without training wheels first, why would you do the same thing as an artist?
