And then here's me having to have my wife help my daughter with her middle school math assignments because they entirely mystify me.

[–] [email protected] 7 points 2 hours ago (3 children)

I had no idea that people struggled with this so much and have come up with such crazy (to me) ways of figuring it out.

Most of the world, if asked to write down numbers 1-100 on a line, would do so left to right. The < and > symbols are arrows pointing left and right. To the left the numbers decrease (less than) and to the right the numbers increase (greater than).

All this stuff about crocodiles and ducks seems like such a bizarre way to remember it!

A mnemonic device is a mnemonic device.

I think about how the symbols have two sides, one is a point (small side) and the other is wide (big side)

[–] [email protected] 2 points 57 minutes ago

Your explanation is no less crazy lol.

[–] [email protected] 1 points 1 hour ago* (last edited 1 hour ago)

I think about it the same way I think about + and -. I don't think at all. I just know.

Maybe it's because I'm a programmer and I encounter comparators more than addition and subtraction.

I know that you can pronounce the emoticon <3 as less than three and it has for whatever reason replaced the crocodile mnemonic.

I got a zero on a math test in second grade because I said "the bigger number is on the bigger side" instead of "the crocodile wants to eat the bigger number", fuck you 2nd grade math teacher who made me hate math by being the thought police.

I never understood why so many people seemingly struggle with these signs to the point they need a mnemonic. The big side points to the big number and the small side to the small one. What even is there to remember?

[–] [email protected] 4 points 2 hours ago (1 children)

Yeah, the symbol is the mnemonic. What does the crocodile even explain? Why doesn't the bigger number eat the smaller numbers?

[–] stevedice 1 points 2 hours ago

Yeah. It would be like saying "Oh, when I see a stop sign, I think to myself they're the same colour a traffic light turns to when you're supposed to stop, so I remember to stop"

big side, big number

[–] [email protected] 8 points 14 hours ago

I earned it as the larger part being on the side of the bigger number

[–] [email protected] 179 points 23 hours ago (22 children)

It's a thing that I've always thought that people over-complicate. It's just there, the small side with the small number the big side with the big number...

[–] [email protected] 101 points 23 hours ago* (last edited 23 hours ago) (9 children)

"The entirety of the small number constitutes a relatively smaller portion of the big number. Thus, the open side of > points to the smaller number to indicate that it's a magnified view within the larger number."

I hope this helps overcomplicate things for you. We must all return to crocodile.

Directions are one of the most confusing aspect tbh. Bounding is difficult..

[–] [email protected] 12 points 15 hours ago (3 children)

<3 is "less than three", and 3 is "three" so logically < is "less than"

[–] pancakes 2 points 6 hours ago

Also < looks like an L at an angle

[–] starman2112 12 points 11 hours ago (1 children)

I try this, but I always get <3 mixed up with Ɛ>

[–] [email protected] 9 points 9 hours ago
[–] [email protected] 10 points 14 hours ago

aww love you too bro <3

[–] [email protected] 10 points 15 hours ago (3 children)

Surely in theoretical physics, the most common use of > is in a ket (eg. |ψ>).

[–] [email protected] 19 points 15 hours ago (1 children)

Crocodile want to eat cactus ?

[–] [email protected] 1 points 8 hours ago

That cactus is the devil!

[–] [email protected] 14 points 14 hours ago (1 children)

arguably, it's |ψ〉, which is not the same as >

[–] TriflingToad 7 points 14 hours ago (2 children)

wow that's a big difference (I have no idea what you are talking about)

[–] [email protected] 6 points 12 hours ago (1 children)

It is just a notation for linear algebra and linear operators on complex vector spaces together with their dual space both in the finite-dimensional and infinite-dimensional case. Really quite simple stuff actually...

[–] TriflingToad 4 points 11 hours ago

smiles and nods, smiles and nods...

[–] [email protected] 8 points 14 hours ago

I think 〉 means a very hungry (or at least large mouthed) crocodile, and > is just a normal one.

[–] [email protected] 4 points 12 hours ago (1 children)

No? Not everyone's doing work on quantum systems. Far from it. Most people do not need to use Dirac notation.

[–] [email protected] 3 points 11 hours ago

I guess not. Its just that when I hear 'theoretical physics' I immediately think of particle physics (and related fields). I have this idea that in most branches of physics people just say the topic, eg. astronomy, material sciences, or whatever; and don't usually specify whether they are doing theoretical work or experimental/empirical work. But in particle physics ... my impression is that people are more likely to specify. Anyway, that's just my own bias I guess.

MesseR Rechts, GabeL Links.

I don't think I've ever been taught a mnemonic with animals

The small number is on the small side of the symbol, the large number is on the large side, it seems pretty intuitive to me, to be honest.

The teacher who first taught me told me “Pac Man wants to get the most points” and that stuck with me

"Points at the smaller thing"

Every time I watch a student stall out on inequalities I ask "it's the crocodile isn't it?". Without fail, they've got confused by it and as soon as they hear "points at the smaller thing" they have no issues.

[–] [email protected] 38 points 20 hours ago

yeah its literally a graph. the bigger side is the bigger number. the smaller, surprise, smaller number.
