The hard part of math isn’t understanding esoteric symbols it’s the theory behind it and it’s application. Number theory will mindbreak almost all people.
Oh cool, I know who this person is, she did a couple of amazing videos on Bezier curves and splines
Which makes the integral sign ∫ a non-discrete for-loop
That does not help. What does non-discrete mean?
I disagree. It’s a while loop, because a for-loop is finite, so you can’t count to infinity with it.
I wanna see how you get a while loop to actually go to infinity. I’ll wait…
on second thought, no I won’t.
You can reduce this readable code into one line of confusing python list comprehension that runs 100x slower!
Just notational difference other than presence of mutation… How is it harder to understand
3 + 6 + 9 + ... + 3nmeans compared to the for loop? Is repeated addition hard to grasp?No it’s not harder to grasp, just less concise. Summation and Product notation exist for the same reason we don’t say “a discernible but subtle level of humidity” and just use “moist” instead - it’s more convenient. People can be taught to readily understand “moist” or the summation notation. It’s much harder to teach people to read the longer notation more quickly.
Freya is a really good programming maths communicator so it doesn’t surprise me
Not knowing about Splines before
Feeling like understanding Splines afterwards 🥰
i hate that we all got so frightened about math. it’s genuinely fun to learn how it works when you’re not being forced to in a school setting, which was just a fucking nightmare for no reason. i had this former navy DI lady teacher in gifted kid algebra [so already a year ahead] yell at me for asking questions; she wasn’t going to ‘hold my hand’ thru the homework, which was quite literally her fucking job
Turning 35 in a month and I’ve just started learning maths again after being afraid of it because of a similar situation to yours.
It’s surprisingly easy. I used tl give maths tutoring to finance my university degree. What I’d do is let the kids do one exercise task from their school books to see where their difficulties were. While they were on it, I quickly read through the relevant sections in the book, and it was so easy every time that I knew everything I needed to know after a few minutes. Like literally stuff that took weeks at school within minutes.
School just sucks and makes it really hard to learn anything. Almost everything kids learn at school is actually really easy.
Well it’s harder for them because they are kids and their brains are still developing. You’ve had a lifetime of experiences to draw from where you use math concepts subconsciously many times a day.
Totally true. They haven’t learned to learn yet, they aren’t learning because they want to, or even because they need what they learned.
But the point I was trying to make is, that many adults are still afraid (and many even strongly so) of maths, because it was hard for them at school. But it probably wouldn’t be hard for them now.
This post confuses me. Why would code be simpler than the math notation? Both involve symbolic abstraction of basically the same complexity
It’s a Meme? Do you ask the same under other memes as well “What is the reason?”
