A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

I agree, we need to rewrite it in rust

Don't forget to add some AI modules for dynamic content generation.

You never specified what type a function is, such as 𝑓 : ℝ → ℝ?

[–] snek_boi@lemmy.ml 7 points 1 year ago (1 children)

Fair enough, I changed "never" to "rarely" :) I'm actually curious, did you have to specify the 'type' often?

[–] xigoi@lemmy.sdf.org 5 points 1 year ago

If I remember correctly, good textbooks always specified the type. There were even exercises like “find the maximum possible domain of this function”. And in higher-level mathematics, it's pretty much a sin to not specify the type.

Also, everyone keeps using one-letter variable names without any comments in code

Terrible naming all around in maths, half the shit is named after dead French or German dudes.

Leonard Euler was just the 16th century maths version of Alan Smithee that people wrote on papers as a joke, and you can't convince me otherwise.

My experience with math class has been quite different. Most exercises specify the domain of the equations, and I've been taught to always work out the set of possible solutions (when it's non-obvious) before solving an equation, though I usually forget to do this and still end up with impossible states...

That sounds exhaustive in the good sense. Rigorous. Would you say your math education was particularly good compared to that of, for example, the rest of your country? Could you know, perhaps through standardized testing, if it was good compared to the rest of the world? Would you attribute the exhaustive domain and range statements to just the book, just the teacher, or just the school administration, or some combination of them?

And then use an operation which is only defined 2 pages later..

also in calculus the answer is typically 1 or 0
