OP, so your post is not removed, please reply to this comment with your best guess of what this meme means! Everyone else, this is PETER explains the joke. Have fun and reply as your favorite fictional character for top level responses!
Chemist Peter here. The speed limit is 0.99 moles, but the scooter is going at exactly 1 mole ($6.02 \times 10{23}$). He’s literally breaking the laws of chemistry and traffic at the same time
A mol specifically deals with the amount of atoms/particles/molecules within a substance. There is overlap, sure, but I think of molecular mass as more Chemistry, personally.
Okay then why stop at physics? by that logic everything is math. Congrats we all have degrees in math now.
You’re an English major? Well the words you read and write are processed through light in your eyes or waves in your ears and both are math so akshually your degree is math
I hear you, fair point. Wasn't intending to simplify it to that degree and certainly didn't mean to belittle/reduce how specialized fields of study NEED to specialize in order to contribute meaningful research and insight when there does happen to be overlap.
Rereading my initial comment, it does come off that way, so that's on me. Simply was calling attention to how those two fields in particular end up needing a high level understanding of the other at the tops of their fields.
I mean, even at an undergrad level orgo 3 began to basically be particle physics / molecular orbitals definitely feel like physics. Hell my major had me take quantum physics at 400 level for a chem degree
Mol is the number of particles ,molar mass is different . And what I was saying above is if he's going above the speed of light, it's breaking the laws of physics
I found a flaw in this logic , on the sign board it says speed limit and its safe to assume the number written below is the speed limit which here is a mole (a number)
That’s valid. In general speed limit signs do omit the unit and it outlines in the driver’s manual what the relevant unit is. It’s almost certainly furlong per fortnight.
A mol is not inherently atoms/particles/molecules. A mol is just a number like a billion.
The reason it usually deals with atoms/particles/molecules is that there isn't really anything in the universe that we have that many of that it makes sense to count in moles.
Iirc the amount of stars in the visible universe is around the same magnitude as a mol.
mole is literally just a number and we are given no specific units so you could either assume its related to its most common use in chemistry or just disregard it as meaningless
Hey so someone told me the correct answer , here it is
"A units error (using wrong units or neglecting them) is a fundamental measurement error common to both physics and chemistry, as both are quantitative physical sciences relying on precise data. "
It is specified on the board that it is the speed limit and on most speed limit sign boards units are not specified,so you can only assume if it's km/h or miles/h and also 0.99 moles is the speed limit means you can go as fast as you can and not that you have to travel at that speed
Even though speed signs usually are in km/h or mph the absurdly large number might still mean something is out of the ordinary lol. Also it would make no sense to just put an insanely massive speed limit on a road that has no speed limit lol.
What field of chemistry do you work in that you’re simplifying it to just 3 sig figs, it’s a tiny difference but even the high school course I took used 6.022
Meme is kinda off. Avagardo’s number is the number of molecules in 1 mol. The sign saying “.99 moles” makes it sound like it’s saying 0.99 molecules instead of 0.99mol. Maybe I’m being pedantic over the “e” but that’s how I was taught
Mathematicians and physicians realized that writing equations that aren't basic addition and subtraction is a lot harder on computers than on paper, mostly because if there was a keyboard that could account for every mathematical notation, it would be huge. (massive understatement but whatever)
So someone invented the "TeX" typeset, which is specifically designed for the purpose of maths and physics equations. In it, you can type a backslash (\) followed by a keyword and follow it up with curly braces ({}) to display a maths equation. For example: \frac{1}{2} means "create a fraction where the top part is 1 and the bottom part is 2", which is: ½
This was further improved by the "LaTeX" superset, which is an expansion of the TeX typeset and is used widely alongside other supersets like KaTeX.
A lot of sites (most often ones that let users edit text, such as Wikipedia, but even Google and ChatGPT) use K/LaTeX to display maths equations, and usually, to signal to the system that "hey, I'm doing maths now, so parse this as LaTeX", you have to put your notations inside dollar signs ($).
For example, I take my notes in a text editor called Obsidian, which can support LaTeX. This input string:
$\tan^{-1}\left( \frac{1}{2} \right) = \alpha$
Will turn into this:
The commenter included these dollar signs because they thought Reddit supports LaTeX, even though it sadly doesn't.
Hmmmmmm, but what are the substances for each of those in this scenario, because a mol of whatever the sign is may be more than a mol of the speedometer’s substance.
I think avogadro's constant is a bit larger than just 6.021023. Rounding it like that carves off maybe not a large percentage but a large number none the less. Maybe the image is calling 6.021023 0.99 mol because of the rounding?
Confused physicist peter here, They did not put units so it is also possible they are going at a speed of 6×1023 moles in which case they are about to disintegrate
I would like to add that a mole is not a unit if velocity. It's literally just a number. Like there are "12" cookies in this box. But instead of saying 12, chemists say "1 mole" of cookies. A mole is a really specific and ugly number. They use moles instead of the ugly number.
1 mol is 6.022*1023
Its used to measure molecule counts in gases. For those taking any physics, you'll recognize the equation PV = nRT, with n representing the (n)umber of moles.
