I'm not physics major, but if I was this would be a major help. This seems quintessential for thermodynamics, at least for learning it. Plus I learned that the word "enthalpy" exists! Good video.
I saw a minor variant of this square a fair bit when I was a TA for Physical Chemistry I lab(mostly Thermodynamics and Chemical kinetics) last semester and had to refresh my memory on the subject as someone who would largely be considered a biochemist. Also, we use A for Helmholtz Free Energy.
Reminds me of my thermo class, where the mnemonic we were was "Vokda And Tequila May Give Severe Headache Pain", where the letters were put on the square starting from top left and going row-wise down to the bottom right.
alternatively : remember dU = TdS - pdV + \mu dN, learn the structure of a legendre transformation and don't forget the cross partial derivative rule or just do the latter and learn the potentials you're interested in
I actually have my thermodynamics final next week so thank you very much for this video Edit: i can now proudly say that this video really helped me in my thermodynamics final and it could actually be the difference between just an ok grade and a good grade. Thank you again for this great video.
I remember Maxwell's Relations by remembering the order SVTP. Then first I write these variables with partial signs in a grid with S at top left. If I go counterclockwise while writing the variables on grid as SVTP I'll get +ve sign and if I go clockwise then I'll get -ve sign. Now for the remaining two Maxwell's relations, I write S at the bottom right and follow the exact same procedure as above.
Yo Dotson, nice trick. Really wish you did this about 2 years ago though 😅😅. Also, we haven't forgotten about you for an epic collab. Lookout for an email within the next few weeks. PS: we're feeling the physicist / part-time trucker look you're rocking this video 😄😄
We did it upside down compared to you VFT in the top row EG in the middle SHP in the bottom. Of course we did it after I crashed and burned in phys chem trying to memorize these horrors by heart... if I had a choice thermal would always come before phys chem, it just clicked so much better and I would have been able to understand the chemistry so much better if I'd already grasped the physics.
As a AP physics, AP cal AB, and AP chem high school student, I’m going to keep this video in mind when I get to this level, so for future KT, I thank you 😂
I had heard of this mnemonic device, but only now I understand how it works. Probably not gonna use it to rederive the differentials of the potential (those are easy to remember anyway), but if I need a maxwell relation from nowhere this looks useful to get the one I need instead of having to figure out which potential I have to take the second derivative of :)
Also Germans: "Unheimlich viele Forscher trinken gerne Pils hinterm Schreibtisch" which translates to "An incredible number of researchers like to drink pilsner behind the desk" 🤣
Once you get the differential forms you can get easily the maxwell relations applying that the coss derivatives are equal (Schwartz theorem applied to the differential form itself)
It's often called the Born square. It appears in lots of thermodynamics textbooks. There's a slightly more "advanced" one in this paper that I read a while back. It gives you more than the Born square, alone, does. It's pretty neat. lptms.u-psud.fr/membres/trizac/Ens/M1GP/ThermodynamicSquareMnemonic.pdf
Hmmmm.... We never did a Mnemonic device like that. We just called it the VAT-VUS box which I guess technically is a mnemonic device. Statistical Thermodynamics was actually a class I really enjoyed taking.
U literally just saved my grade. Dr. Oliver hasn’t done an online lecture since the pandemic hit and just increased the final percentage from 20 to 30% of our grade
As a electrical engineer this is very confusing: P is for Power?! H for Entropy - what the heck is enthalpy? Plus there are not only Maxwell´s Equations, but also relations?!
Hey Andrew! I know it's an older video but I hope you will still see my comment. Can you tell or even recommend, which book(s) you have used while you were studying Statistical Physics & Thermodynamics? Would be very helpful! Love your content! Cheers
In gradschool I used pathria for stat mech. Already assumes you know a bit of thermo though. A lot of people use kittel in undergrad, but I never used it so I can’t speak on it. We used sear-Salinger which was alright.
I'll have to remember this for upper division... Curious about the actual derivations of these relations without the mnemonic, but prob should finish Chem courses for better grasp of Enthalpy and Helmholtz first tho lol
The beauty of this channel is; you're a 40 year old bloke and forgot all the physics from your engineering degree and need to remind the brain how smart you once were.
Depends on how deep you want to study the subject. I am studying nuclear engineering so thermodynamics is basically my life lol. I would say that if you just wanna know the basics of the subject, any Physics I book is good to be fair. If you wanna get deeper into the subject I would say you should buy an Engineering thermodynamics book (engineering is much more about thermodynamics than physics is). I think the best is “Fundamental of Enginnering Thermodynamics” by Moran. It covers all the most important topics and also covers the heat transfer problems. If you wanna get even deeper into the subject, you should study Fluid Mechanics and then any book of “Thermal-Fluid Mechanics” would be good. Personally I love the Incropera’s. These are the best I can think of!
This feels like a cheat code to a level of physics I have not yet unlocked.
"so lets connect the P to the V" giggady
*All boys in the class starts wheezing!*
For the chemists out there: Good Physical chemists Have Studied Under Very Able Teachers. (Helmholtz energy is A in chemistry)
For chemical engineers: SHPUGVAT
A for Helmholtz is best.
@@jasondyseng1182 tbh I find it easier to memorize this instead of the long sentence
Hahaha - trying to memorize all the Maxwell equations for my Physical Chemistry course. I used Awesome instead of Able but this pneumonic is Amazing
Thermodynamics is literal hell on earth for us engineers
I cannot relate enough
Mech. And Chem.Eng. can relate.
Love this sort of content. As a PhD student it's always great to discover possible ways to consolidate information via mnemonics and alike. Thanks!
I have my thermodynamics exam in a week and a half and this is so helpful, thank you very much!
I have an exam on reducing derivatives to prepare for, and this video made everything click😮💨 Thank you :)
have my first thermal paper of the course in 4 days... my freaking god you are a life saver my man
why the hell did this video come to my algorithm after failing my graduate application exam, when i watched this channel for like 3 years
Dang I feel for ya.
I'm not physics major, but if I was this would be a major help. This seems quintessential for thermodynamics, at least for learning it. Plus I learned that the word "enthalpy" exists! Good video.
This video was conveniently posted on the day my test got rescheduled! Thx
Always loved me some Maxwell's relationships and topics! Thank ye for the advice and informative content!
My teacher introduced this today, different orientation of letters in the square same order but your video makes much more sense. Thank you
This channel is making me question wanting to major in compE
I remember watching this in high school and being so confused. almost 2 years later and its on my thermo test :)
This is exactly what is going on in class and was in deep shit with exams next week. Thanks a lot bro.
This is very useful for my semester exams ..Thanks Andrew
Love From India ❤
Perfect timing for this video. I just learnt this for the first time yesterday.
I am studying to catch up on my thermal physics. Thank you so much andrew, this was super helpful as always!
Life saver man, need this for PChem Thermo exam.
I saw a minor variant of this square a fair bit when I was a TA for Physical Chemistry I lab(mostly Thermodynamics and Chemical kinetics) last semester and had to refresh my memory on the subject as someone who would largely be considered a biochemist.
Also, we use A for Helmholtz Free Energy.
I cant even thank you enough for this. You just saved me several hours of stufying! Thank you SO MUCH!
I just had a lecture on Maxwell’s relations this week, gotta love how much this video helps me
Ayo wtf this is amazing, thanks- 2 days before exams
Really great way to remember. Thanks for the video.
Ok!!. I have a Ph.D. in thermodynamics and I didn’t know that mnemonic tric !! Nice, I think I am gonna teach this to my students !
Reminds me of my thermo class, where the mnemonic we were was "Vokda And Tequila May Give Severe Headache Pain", where the letters were put on the square starting from top left and going row-wise down to the bottom right.

or just do the latter and learn the potentials you're interested in
Yeah, works better for me. Especially since the square becomes a spicy octahedron once you throw magnetization in.
@@sarcasticsteve7622 I can't wait to do more physics after freshman year...
8:04 lmao
I have no idea what Thermodynamics is but this looks really helpful
Hey Andrew it looks like you're invited to PQI in April! 😮 Was shocked to see you there tbh! Congrats!! 👏
Exactly the topic I needed covered. Thank you Andrew-sama
Thanks so much . I am getting lots more than you derived from your square.
I was looking forward to a Dotson video all week.
P.S. can we have a discord server for our #1 tensor boi
Ahhhh I wish I saw this last semester when I took thermalphysics 😂. Awesome video as always andrew!
You explain things very well. You should post more mini lessons! Maybe on things like magnetism and electricity.
Nice video. I'm a chemist student and we do thermodynamics at physical chemistry. I'll use it. Thank you
I just started my thermodynamic course and this is really helpful!
I actually have my thermodynamics final next week so thank you very much for this video
Edit: i can now proudly say that this video really helped me in my thermodynamics final and it could actually be the difference between just an ok grade and a good grade. Thank you again for this great video.
Bruh, why could my Thermo lecturer not teach us this? Would have saved me on my exam.
Wow its really nice to see that physical chemistry will be useful in physics at some point
Lol you released this video literally right as I was taking a test on it an hour ago
Many thanks. We need videos such as this. :D

Just doing classical thermo for the first time tyvm!!
FINALLY A VIDEO ON THIS!!!!!
This was literally uploaded the same day that I learned this in themo recitation
I love mnemonics, thanks Andrew ^o^
Awesome!! Thanks a million!!!
i would kill for get this guy as a teacher at my university
I had to learn this last semester when I took physical chemistry, it was a challenge but I got an A in the class
It's unbelievable! Awesome!
Yo Dotson, nice trick. Really wish you did this about 2 years ago though 😅😅. Also, we haven't forgotten about you for an epic collab. Lookout for an email within the next few weeks.
PS: we're feeling the physicist / part-time trucker look you're rocking this video 😄😄
Eigenbros I’m actually a trucker who is a part time physicist. And sounds good!
wow..thank you for sharing. sending love from the Philippines
Very Helpful, Thanks 👍🏻🙏🏻
There's one equivalent for italian: "Una Volta Avevo Tanti Giochi Poi Ho Smesso" starting the square from the middle left and A=Helmotz free energy
Fisica Tecnica be like:
Great and easy way to remember thanks a lot love your videos....
This is awesome. Wish I had this in thermo
Thank you so much! Very useful! 🙏
5:13 and the reaction face at 5:17 ... that's how you get a happy little accident
Very Fine Teachers Expect Good Students High Performance

That's one monster of a mnemonic rule holy crap.
Reminds me of Phil from modern family
German: "SUV-Fahrer tragen gerne pinke Hosen"-->"SUV-driver like to wear pink trousers"
Also Germans: "Unheimlich viele Forscher trinken gerne Pils hinterm Schreibtisch" which translates to "An incredible number of researchers like to drink pilsner behind the desk" 🤣
... and people say that Germans don't have a sense of humor!
Great mnemoics! Wish I had these in mind last semester, though :/
Can't wait to use this when I'm not a freshman

OHMyGOD a new video
I had my thermo exam on Wednesday, unluckily, this was not uploaded before then 😢
The Rosetta Stone of Thermodynamics!
Get a load of THIS guy

I'll take thermo next semester...exited to use this
Don’t be... it’s shit 😂😂😂
Hmmmm.... We never did a Mnemonic device like that. We just called it the VAT-VUS box which I guess technically is a mnemonic device. Statistical Thermodynamics was actually a class I really enjoyed taking.
Valid Facts (and) Theoretical Understanding Generate Solutions (to) Hard Problems. I think I read it in Callen: "Thermodynamics"
Had to rewatch this for my thermal physics final
U literally just saved my grade. Dr. Oliver hasn’t done an online lecture since the pandemic hit and just increased the final percentage from 20 to 30% of our grade
Make more content like this please..
Literally love you
As a electrical engineer this is very confusing: P is for Power?! H for Entropy - what the heck is enthalpy? Plus there are not only Maxwell´s Equations, but also relations?!
Literally just saw this after a thermo exam...wish I saw it before lol.
Absolute genius
Hey Dotson 😊❣️

I have to repeat the exam that I failed the next wensday on this stuff, you are jesus for me this time🤣
Hey I understood that and I'm not even a physiscist 😀 I had a thermo course in third semester of life science technologies
The beauty of this channel is; you're a 40 year old bloke and forgot all the physics from your engineering degree and need to remind the brain how smart you once were.
Superb..
Yo have you fealt pressure while learning the enthalpy?
No pressure at all, but it was TdS
Just learned this. Lets goooooo
I wanna ask you guys, is there a simple way to mesurate the LogP value of a compound?
boboddy. Okay were making acronyms what does the first b stand for?
wow thank you so much!
What would be a good book for thermodynamics? I can't find one.
In Germany the books of Thorsten Fließbach or Stefan Nolting are the way to go. Try to get a translated version maybe (if something like that exists)

5:16 The P to the V. I get why you are laughing 😂
The more you buy, the less it cost, until most of science is almost freely accessible 😀
This is Maxwell's mnemonic. The James Clark Maxwell
Thank you this is fantastic why didn’t I know this when I was in s makes it so much easier, I studied my ass off, damn
