I also have a theoretical degree in physics

You're theoretically hired!

I'm a mechanical engineer, and I often have to do a double thumbs up with my hands like b_d. It's the only way I can remember what comes first in the alphabet. In danish you spell boat båd, and if you mess up the order the b and d will be on the outside of the boat and drown, like dåb. Still works 20 years later

Do you have dyslexia or something like that by chance? I don't think I've met anyone who gets confused between b and d. (No offense, I'm just intrigued)

[–] kamills 8 points 1 day ago

I don't have dyslexia. But I did only learn how to read and write in 5th grade.

Once I saw a (tailless) cow wearing uniform.

I've always been a fan of using > and < but in the general use of lesser than or greater than, however, the symbols were always interchangeable to me since it always depends on where you put the defined integer, correct?

If I want to say something is less than 37. It can either be 37 > or < 37.

Because in that scenario the imaginary integer n is always on the opposite side of the symbol.

37 > n

n < 37

So why did > ever become greater and < be less than? Doesn't it also depend on how your text is written? If people reading from right to left or down to up vs left to right and up to down, means it's reversed.

The open part of the caret is where the bigger number is, the opposite side is where the lesser number is.

Yes. > is "greater than" because you're reading left-to-right. 12 > 9, read: "twelve is greater than nine". When reading in a right-to-left script, it's the opposite, but because of how the BiDi spec works, the same Unicode character is actually used for the same semantic meaning, rather than the appearance. Taking the exact same block of text but formatting it right-to-left (using directional isolate characters) yields "⁧12 > 9⁩", which is still read as a "greater than", just from right-to-left.

Hopefully that makes sense.

So yes, if you copy the > character and paste in any directional environment, it will retain its meaning of "greater than".

Edit: on my phone, the RTL portion is not formatted well. If you can’t see it, try a browser.

You just blew my mind with that unicode trivia. Super cool !

i feel like i’ve been using latex for so long that at this point my brain has been rewired to see ≤ as ‘\le’ (less than or equal to) and ≥ as ‘\ge’ (greater than or equal to), and then this dictates how i view < and > as well

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

One of my favorite teachers taught computers and pointed out that the less than symbol is towards the side of the keyboard with smaller numbers.

I still sometimes think of pillars of one building when I think of concept of "tomorrow" because seeing those pillars was supposedly the first time in my childhood when I heard about "tomorrow".

I was being disruptive in first grade and kicked out of class then we learned this (ADHD and boredom). I tried to peak through the window and do the crocodile arms to learn it, but my teacher saw me and came out and told me to stand at the end of the hall. I didn’t really learn this until 3rd grade. Ironically, math was my favorite subject for all of k-12.
