That Griffiths E&M joke is golden. I just had my midterm on determining the coefficients Cn using fourier’s trick, laplace’s equation for voltage in spherical with legendre polynomials, Cartesian PDE’s, multipole expansion, and electric fields in matter (polarization vector, electric displacement, dielectric materials). What a topic The exam average was 53%, I scored 88%
i’m in high school right now and in my math class we’re learning taylor series and power series and all that (literally have a test on it in 8 hours) and listening to you talk about how much you use taylor series makes me really excited for my physics major considering taylor series make me want to cry! they take so long to do! i hate them! they’re useful but i hate them.
I was reading astrophysics lecture notes the other day and it said "neglecting all constants of order unity" and straight up binned a factor of ~3 in the process. Not as in, we moved to a system of units such that it disappeared, or we cancelled it out. We just deleted 3 and called it a good estimate.
The reason engineers don't need to be precise is because they just build stuff to a level of safety well above what they need it to be, so that way they don't precision
Your explanation is correct but there is also a need to be accurate because if you calculate the "required" safety level incorrectly then your error buffer in design may not be adequate. For example in power engineering where they regularly work with transmission voltages of 275 kV, a small discrepancy will have a large influence on the results. But no one really approximates pi or e since its available as a button on a calculator and on all calculation/modelling software suites so i'm not sure why its a meme
u is sometime used to indicate position. A double dot above a variable is newtonian notation for a second derivative with respect to that variable. So u double-dot is acceleration.
Josh Schilmeister a double dot is not the second derivative with respect to that variable (position in this case). the dot derivative notation is reserved for derivatives with respect to time
They're surprised about approximations because it's a change from high school and people don't like change. And most of these memes are made by freshman.
I never understood sin(x) = x. All I ever got was sin(x in degrees) = x in radians, and its not even off, it's like almost identical. The only small angle approximation I learned was sinx = tanx as long as it's below 15 degrees.
sin(x) = x is the first order Taylor polynomial approximation for sin(x). It's only accurate for small values of x, thus the small angle approximation.
I study engineering and physics. I don’t know where the pi=e=3 approximation comes from lol I haven’t used that approximation in either degree. Have used g=10 though... 🤫
Civil engineering junior here, and I’m pretty sure within the entire school of Engineering at my college, nobody has ever used the fundamental theorem of engineering lol. It like only exists in memes XD Besides, if it comes to it we’ll put things in MATLAB with returns like a million decimal places, no need to ever approximate like that 😂
Lol, my favourite joke is newton slaps top of car, car slaps newton back.
That one is pretty good.
Actually I am an engineer and we don't approximate g or pi, so I don't what you guys are talking about
Whereas I have done both of those things
@@AndrewDotsonvideos When I took physics, we approximated g to 9.8 and in engineering we used 9.81 lol
DocAlex blasphemy.
@@GojoSenpai25 I used 9.81 on a physics problem and I got it wrong because they used 9.8
I don’t make physics memes, but I definitely like seeing them!
Me: An engineer
Prof: I need you to be accurate to the 7 sig figs or you get a zero
Physics Students: Lol, engineers go π=3.
Astronomers: Only power of 10 matters the rest is negligible
Engineer: Physicists go "g = 10."

Thanks for reminding me mastering physics is something that existed
4:20 glad you liked my meme Andrew
also u/atticus_grinch is my friend at school and there were a couple of his on here too
At 0:08 "if it's not physics related he PHYSICally can't laugh." I see what you're doing there Andrew, you're playing a dangerous game.

Thank you for featuring my Fundamental theorem of engineering meme Daddy Dotson😍
When I saw the MasteringPhysics message in one of the memes I twitched.

He’s approximating the amount of approximation memes 😮
These memes are preparing me for my 3rd year.
I'm literally going over Laplace's equation and uniqueness in my E&M class right now
This video has become the very thing it swore to review.
@8:07, did Quagmire put you up to that? Putting 8,008 into a calculator?
8:12 If it was a math meme, it would have been "Proof is Trivial (leaves proof blank)"
yea that's 50% the other 50% are 'by inspection'
“Ket your head out of the gutter”
...I almost laughed hard enough to wake up my roommate.
Your so cool and admirable, keep up the good work dude!
None of those Reddit posts are mine. But at least I got a comment screen-cap at 1:02. Papa Andrew has noticed me!
Stopped all my studying so I can watch your video bro😀
kaleb dawit this counts as studying!
Engineers approximate? HA we don't even do our own math, someone engineered a software for that
I'm either too cool or not smart enough to understand most of those. My guess is too cool.
How do i pick between a major theoretical or astrophysics (yes in my country u can major in both separately)
5:49 :'( of course I should have known u were taken. y do u do this to my heart.
Wait did Andrew just confirm he's dating Kelly.
It’s bin confirmed ma dude
long before you were born
This joke is trivial and left as an exercise for the reader
4:55 he took so long to get that lol
May I have some Lööp quantum gravity brother.
Lol just saw your comment on alien life from “What on earth?”
The reason engineers don't need to be precise is because they just build stuff to a level of safety well above what they need it to be, so that way they don't precision
And when they fail to calculate, they go to jail.

>"But no one really approximates pi"
Not for real world calculating, but for example quick cricle circumference aprox, it works fine to say 3.
you have to be more precise only insofar as it pays off
No bro , my dad is a engineer, his team calculates metrics of lens (dia) etc upto accuracy of 0.1 micron ... So ya
Just scrolling to find the explanation to that joke

you need to host meme review!!
I have a midterm in 2 days on Laplace's Equation and the Uniqueness theorem.... I'm so scared dude.
I send out top of the week of /r/physicsmemes to our sps members weekly for whenever I tell them what the plan is that week 😊
Is the Uber one about acceleration being the second derivation of position

I see that ISO 8601 date format 👀
5:20 nice meme
Oh shit man, I have the same poster. #GottaLoveAlbie
0:50 Im studying electrical engineering and i havent seen anyone saying e=pi=3 :D
Approximate sin(x)=x and nobody bats an eye. But say π=e=3, and the whole world loses their freaking minds. Ever thought about that, Batman?
Hello, fellow exclusive member of the.... Clüb
A little late to the party but 2 of those memes were mine and I do watch your videos

Most of them were funny. Gotta make them in animated videos.
