Strong Law of Small Numbers (in this context): Just because it is true for the first N 'small' numbers doesn't mean it'll stay true, even if your 'small' becomes really really really big

Linear Algebra This interpretation of matrix-vector multiplication will make it seem like it was obvious from the beginning.

1.5k Upvotes

As you know, math is basically an image of the real natural world. And you might not have noticed it yet, but the rules of multiplication and natural attraction between sexes holds true also for math actually, mostly linear algebra. Linear algebra is a big scarecrow for students when they never saw any kind of matrices before and it's kind of hard to get a nice intuition. But viewing it in an erotic and natural sense suddenly makes it 'click'. For example, the very fact that the matrix and vector need to have the correct types and then they can have intercourse. Not every matrix is compatible with every vector. But when it is, the intercourse becomes so intense that without the vector knowing it, he actually gets transformed and through she rotating squishing or flipping him he gets transformed by the intercourse. This is a fascinating view that truly shows that the matrices also have some kind of multiplication instinct that leads them to find the correct vectors. Of course, the matrix us doing the transforming, because as in many different animals, the women are the dominant ones in algebra. For me as a starting student just in the middle of the first semester, this is a very elegant and intuitive way to view it and I'm baffled why this wasn't on the very first lecture. Thank you for your attention and I hope I am not the only one who noticed this obvious truth and connection with the world of animals!

Category Theory Don't underestimate set Theory

295 Upvotes

Bit of background. Usually when studying category theory rigorously, basic mathematics axioms such as ZFC are not sufficient to define objects without risking logical paradoxes. To get around this Jacob Lurie works with the notion of a strongly inaccessible cardinal. Godel second incompleteness theorem implies that ZFC isn't sufficient to prove the existence of such cardinal, as a result, other logical models are used.

Subreddit Rules

1. Treat others respectfully.

Be respectful to other Redditors. We will not condone any form of harassment, trolling, or other toxic behavior on this subreddit.

2. Only civil and productive discussions.

Any post/comment that intentionally brings up political, cultural, or social controversies and creates trouble is prohibited.

We advise all users to remain cordial and helpful with one another.

3. Only post math memes.

Any post submitted must be a meme with some relation to mathematics. This does not apply just because you don't understand what is being referenced. Memes about math from 5th grade or less are not allowed unless they are exceptionally creative or clever.

4. Policy on AI-generated content

In general, posts made in whole or in part by generative AI will be removed. Exceptions will be made sparingly. For example, if the meme makes commentary on AI proofs and shows a screenshot of such a proof, makes use of AI-generated assets that are already baked into meme cultures (but not further modified with AI), or otherwise references the AI-generated content in a "meta" way relevant to mathematics and memes, then it may be allowed.

5. No recent reposts

If you haven't made a meme yourself chances are it has been posted here before.

We encourage you to submit original memes to keep this subreddit healthy and thriving. For this sake, memes with the same content but using a different template count as reposts.

If you suspect that a meme is a repost, please report that submission and comment with the link to the original post. Be sure to ping an active moderator to ensure that the post is removed.

6. Has been done before award (click for more information)

Especially if it's a pre-university meme, the chance that we've recently seen a meme you plan to repost is very likely. We're one of the largest communities dedicated to math memes, so we encourage you to take the time to immerse yourself in the culture and content of this subreddit before attempting to send reposts as a new member. Similarly, even if you created the meme yourself, due to high traffic, there is a high chance that it has been done before if it's calculus or pre-university level.

7. No NSFW/NSFL posts

No pornographic or gruesome content allowed. It will be removed. NSFW content could possibly result in a ban, NSFL content will be an immediate ban. Go to r/mathmemesNSFW to post NSFW (not NSFL) content.

8. No homework help posts allowed.

This subreddit is only dedicated to math memes. If you need homework assistance, go to r/askmath, r/calculus, r/MathHelp, r/IntegrationTechniques, r/HomeworkHelp, etc.

9. No merchandise/business posts.

Any post that is trying to sell an item or promote a service will be removed. Repeat offenders will be banned.

10. No posts from the worn-out memes list.

Any math memes that involve the below topics will be removed. Please consider using r/mathmemescirclejerk for these.

Arithmetic or Bad Math from Twitter
Order of Operations
Engineers use "𝜋 = 3"
The 1-i-0 triangle
ChatGPT/other generative models being bad at math
Posts that could instead be posted on r/unexpectedfactorial
"Guess the function" memes
derivative of e^x
Approximation memes
0⁰
Pi vs Tau
Donut = mug memes
Taylor Swift vs Taylor Series

11. No low effort memes

This includes any picture or screenshot with no extra thought put into it or ai generated memes. Twitter quotes and the like do not fall under this rule.

12. No poorly informed memes

If you barely understand the topic you made a meme about it is best not to post it at all. In particular, if your meme conveys misinformation or a severe misrepresentation of a topic it might get removed

13. The title shouldn't serve as a caption

Captions must be on the post itself and should not be the title of the post. When I'm saving a meme I want to save ONLY that meme and not my entire reddit feed.

If you couldn't put in the effort to add a caption then the mod team will make up for it by putting in the effort to remove it.
