Mnemonic Device For Thermodynamic Potentials and Maxwell's Relations

[@shafkatmehmood7216]

This feels like a cheat code to a level of physics I have not yet unlocked.

[@aadithyaganeshram3758]

For the chemists out there: Good Physical chemists Have Studied Under Very Able Teachers. (Helmholtz energy is A in chemistry)

[@jasondyseng1182]

For chemical engineers: SHPUGVAT

[@Ottmar555]

A for Helmholtz is best.

[@hiro6406]

@@jasondyseng1182 tbh I find it easier to memorize this instead of the long sentence

[@piercebaker4530]

Hahaha - trying to memorize all the Maxwell equations for my Physical Chemistry course. I used Awesome instead of Able but this pneumonic is Amazing

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!

[@artemisgeldman3327]

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.

[@laurasuarezcrespo7540]

I have my thermodynamics exam in a week and a half and this is so helpful, thank you very much!

[@RC32Smiths01]

Always loved me some Maxwell's relationships and topics! Thank ye for the advice and informative content!

[@brooklynclarke4913]

I have an exam on reducing derivatives to prepare for, and this video made everything click😮‍💨 Thank you :)

[@anirbanmohonta4724]

have my first thermal paper of the course in 4 days... my freaking god you are a life saver my man

[@Mystictiki]

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.

[@System.Error.]

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

[@AndrewDotsonvideos]

Dang I feel for ya.

[@joejscrispy]

This channel is making me question wanting to major in compE

[@atharvsawant7509]

Perfect timing for this video. I just learnt this for the first time yesterday.

[@88GTA]

My teacher introduced this today, different orientation of letters in the square same order but your video makes much more sense. Thank you

[@RegalRobin]

This video was conveniently posted on the day my test got rescheduled! Thx

[@prasadpadhye6123]

This is exactly what is going on in class and was in deep shit with exams next week. Thanks a lot bro.

[@NoeDuarte611]

I just had a lecture on Maxwell’s relations this week, gotta love how much this video helps me

[@NovaWarrior77]

I am studying to catch up on my thermal physics. Thank you so much andrew, this was super helpful as always!

[@watchoutusucka]

I cant even thank you enough for this. You just saved me several hours of stufying! Thank you SO MUCH!

[@alexhenczel2097]

I remember watching this in high school and being so confused. almost 2 years later and its on my thermo test :)

[@jesther2575]

Life saver man, need this for PChem Thermo exam.

[@taw3e8]

8:04 lmao I have no idea what Thermodynamics is but this looks really helpful

[@aloksuthar9025]

This is very useful for my semester exams ..Thanks Andrew Love From India ❤

[@pratulyaramprasad7435]

Really great way to remember. Thanks for the video.

[@lewisleslie2821]

Exactly the topic I needed covered. Thank you Andrew-sama

[@prasadpawar7027]

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.

[@mmmao0630]

I just started my thermodynamic course and this is really helpful!

[@rafaeldomenikos5978]

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 !

[@nablahnjr.6728]

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

[@sarcasticsteve7622]

Yeah, works better for me. Especially since the square becomes a spicy octahedron once you throw magnetization in.

[@TasX]

@@sarcasticsteve7622 I can't wait to do more physics after freshman year...

[@maxb.1302]

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.

[@augustineokekeoma1750]

Thanks so much . I am getting lots more than you derived from your square.

[@DotDot-lr9bi]

Ayo wtf this is amazing, thanks- 2 days before exams

[@PoroDango]

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.

[@nucle4rpenguins534]

Ahhhh I wish I saw this last semester when I took thermalphysics 😂. Awesome video as always andrew!

[@kellymama2ninos]

Lol you released this video literally right as I was taking a test on it an hour ago

[@antoniotamayo8964]

You explain things very well. You should post more mini lessons! Maybe on things like magnetism and electricity.

[@TheDeltaboss]

I was looking forward to a Dotson video all week.

[@TheDeltaboss]

P.S. can we have a discord server for our #1 tensor boi

[@supergoofy123]

Many thanks. We need videos such as this. :D

[@nicholasbarnett8827]

Wow its really nice to see that physical chemistry will be useful in physics at some point

[@MBooley]

Bruh, why could my Thermo lecturer not teach us this? Would have saved me on my exam.

[@Eigenbros]

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 😄😄

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" 🤣

[@douglasstrother6584]

... and people say that Germans don't have a sense of humor!

[@thephysicistcuber175]

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 :)

[@seonaxus]

Very Fine Teachers Expect Good Students High Performance

[@seonaxus]

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.

[@latt.qcd9221]

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

Great mnemoics! Wish I had these in mind last semester, though :/

[@razorreef3757]

Don’t be... it’s shit 😂😂😂

[@Benmarkk2009]

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.

[@oraange]

Very useful !

[@federicopagano6590]

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)

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.

I have to repeat the exam that I failed the next wensday on this stuff, you are jesus for me this time🤣

[@Zorpoxx]

Hey I understood that and I'm not even a physiscist 😀 I had a thermo course in third semester of life science technologies

[@ramchandradevkota9501]

Hey Dotson 😊❣️

[@relariis_the_paradox]

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

[@Science4Ever]

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

[@AndrewDotsonvideos]

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.
