i know im asking randomly but does anyone know of a way to log back into an instagram account..? I stupidly forgot the login password. I love any tricks you can offer me.
As someone currently retaking this material at my own university, having been many years since last time, I still haven't found a better guidance through the Thermo laws with exactly the same level of math that my course requires. I love this. A true professor shows up in a suit and is covered in chalk dust by the end of lecture lol.
Dude provided the rough outline of the syllabus in such an artistic manner that feels like you have covered a long journey of the vast course in a short period of time
Needlessly to say, these series lectures are invaluable for people (like me) who are interested in statistical mechanics. Um.. personally speaking, such videoes can help me get a deeper insight into Kardar's books, which sometimes get confused so much. Before this, there were no complete, high-quality recorded courses on stat. mech (If you know, please tell me, and I will be appreciate it), it definitely fills a gap! Thanks a lot!! Looking forward to video courses on 8.334 statistical mechanics of field!!
It's uncut and somewhat difficult to follow on without some of the prerequisite knowledge. However, this is the best out there. (especially for free) It's nothing like ASAPScience or Minutephysics, but this gets the information out there with amazing demonstrations. I always learn better a follow-on video than reading some confusing Wikipedia article.
This first lecture is a bit abstract (not for absolute beginners) but you can learn a lot of things even if you have done some work on thermodynamics before watching this. Thank you.
Actually, at 41:28 when Professor Kardar says it'd be complicated to do rigourosly... it's not so much. We can use the implicit function theorem and thus get F (i.e. the function that solves for c1) in terms of the remaining variables (and of course, when substituted into f, it should also equal 0). The restriction is that we can only get a function that satisfies this property locally and as long as the derivative of f with respect to c1 is not 0. The conditions stated above are actually not satisfied when we have first order phase transitions (e.g. water to vapour). During these transitions we have constant temperature (which gives us the thermal equilibrium between systems) and the only properties we could determine with this theorem are Temperature and Pressure, since (for example) the boiling temperature of a liquid depends only on the Pressure (i.e. ∂T/∂P≠0, and of course the temperature itself). The above limitation implies that the other thermodynamic properties cannot be obtained from the equilibrium condition alone (in fact, it's customary to introduce the property of "quality" to deal with this situation). We can visualize this with the s-T graph (engineering-references.sbainvent.com/thermodynamics/t-s-diagrams.php#.Wo5Qf-FzLIU). We note here that T doesn't change during the phase transition (for constant P=Po, T=Ts) but this means that other properties that do change exhibit a discontinuity: If we have Ɛ arbitrarily small, (T,P)=(Ts-Ɛ,Po) corresponds to a liquid state, whereas (T,P)=(Ts+Ɛ,Po) corresponds to the gaseous state. We know that the gas has higher values for h, u, s, etc. than the liquid and thus we note that these properties are discontinuous with respect to T, this corresponds to the inapplicability of the implicit function theorem in this case. We can imagine this as turning the P=Po line 90 degrees (and rescaling to the appropriate values of the properties), then it's obvious that we have ourselves a discontinuity. Finally, it's worth noting that even when we don't have a continuous F for these particular values of T, we can use the theorem to conclude that for all T where we don't have these particular type of phase transition (this goes both for transition temperatures of system A and of system C... assuming we only have the solid-liquid and the liquid-gas ones (I frankly don't know if there are more of these or not) we would then have 4 (potentially) distinct T's) function F is locally continuous, and in general F would be piecewise continuous once we take the transitions into account.
Also, I forgot to mention that it doesn't matter if "solving for C1" resulted in a multivalued function. The implicit function theorem guarantees the single valued function that matches the original coordinates.
If you had a tool to help you learn and be successful/pass thermo, what would you need in the tool? What issues/challenges did you experience taking thermo? What do you do when you are "stuck" and how do you get unstuck? If you have disabilities, what are accessibility needs to utilize an online tool? Why is thermo a difficult coarse?
At 41:28, the word marked as "[INAUDIBLE]" in the subtitle text is probably "handwaving", in the sense how this term is used in mathematics (see the Wikipedia article "hand-vawing"). Thank You very much for the good and wonderful video!
Also we know that internal forces sum up to zero from newton's third law but not necessarily internal work... So if some dissipative internal forces are present inside the system then the work done will be path dependent
then that dissipated energy will remain inside the system , maybe pressure of the gas will increase, or something else will happen. But energy/heat will not come out from the system.
54:45 would this represent a triple point for water? What about the pressure needed for the vapor to exist in equilibrium? Can anybody help me with this?
This professor’s lecture factors in his own (KPZ) equation, so the theoretical variances in his presentation bears a lot on the Kardar Parisi Zhang equations which may seem nontraditional/confusing to some.
In the equation of heat which he wrote at 1:05:03 , ain't the first term and second term same, I mean, change in work is also equal to the difference between final energy and initial energy.
From 44:00 onward, I did not understand how coordinates of C are dummy variables and are eliminated? Please help elaborating with some simple example..
basically the eqn f(a1,a2...;b1,b2...)=0 is a math. form of the law stating A& B are in Equi. , now whatever coordinates of a and b satisfy that should satisfy F(a...;c....)=F(b....;c....) since its a more general equation of the total system.What he says is that the Equi. of A&B is a constraint and its values also satisfy the first Eqn and the equality would still hold no matter what values you take for c1,c2....so on. So the c's don't effect the relation when a and b values are from the constraint(Equi.) equation and the a and b variables just end up affecting each other when their values are derived from the constraint.Then finally we can turn f(a1,a2....;b1,b2.....) into a form of of only their coordinates and equate them since it's equilibrium. Hope I helped you. Edit:it really isn't complex he's just using the law,converting words to equations then stating the obvious and not very mathematically rigorous analytical results,just a rough mathematical conclusion which would occur in our specific situation.
sir u made a slight mistake at 34:35 by saying that B and C are not connected to each other. But its okay. Its nothing to moan about. Thanx for the nice lecture
The problem with this is contained in the word *equilibrium..* Which has the effect of tying the analysis to classical thermodynamics and avoiding or evading the true meaning of entropy, the macrostate and the Boltzmann equation which tells us how we know God exists and is the creator of the universe because nature is eliminated as a causal agent.
When he is explaining 1st law he first assumes that the system is adibatically isolated. And then he says, in the adiabatically isolated system if he goes from one equilibrium state to other, it is independent of path. But equilibrium is defined between the system abd surrounding. And system is already adiabatically isolated from surrounding. So which equilibrium is he talking about?
+tirannnus The prerequisites are 8.044 Elementary Statistical Mechanics and 8.07 Quantum Mechanics. See the course on MIT OpenCourseWare for more details: ocw.mit.edu/8-333F13
Thank you very much. Just a heads up, when i click on the link for 8.07 Quantum Mechanics (from the syllabus section), it leads me to Electromagnetism II. Thanks and have a great new year.
+MIT OpenCourseWare Dear sir, What is the difference between 5.60 Thermodynamics & Kinetics (chemistry) and 8.333 (physics) Statistical Mechanics of Particles lectures. Are they same, or learning the same thing from different perspective of physics and chemistry.
This is a graduate level class? I'm confused. I have to take "Statistical Mechanics" in my third year (undergraduate) first semester. Is this not the same type of class?
One way of seeing it is that the constraint shouldn't depend on the derivatives of the co-ordinates(since it is an equilibrium). Also, it obviously isn't any inequality.
The first law of thermodynamics is that there can not be a zero temperature measured by human or mechanical but that does not mean either it exist or it does not zero because it has zero frequency meaning it has no dimension like consciousness Second law is that in an only in an isolated system can have work done but as a universal system zero sum is resulted meaning a whole universe can only transform but never had more or less in total energy or matter as a total sum Third law is that the entropy of the whole universe always increase meaning all would disintegrated into lighter material and consciousness will be a disconnected for rather than in solid line of metal or rock. Therefore quantum mechanic is a ultimate evolution not a avoidable state. Like before labor get salary future machine and energy help people get wealth by just thinking and brainstorming meaning jump in promotion is possible even without traditional educational training or licencing
I don't understand how the gas expands from 1 tank into 2 tanks without changing in temperature. If the walls are adiabatic and the gas expands in volume, it must reduce in temperature kind of like when you let hairspray out of the can, the can gets cold. Can someone clarify why there was no temperature change?
Real gases behave exactly as you said, however you observe experimentally that the closest your gas is to ideal (very dilute) the less temperature change the gas experiences in the free expansion, hence you can say ideal gases don’t experience changes in temperature when they expand freely in adiabatic conditions. In short, experiments show that gases that are well described by the ideal gas model don’t change temperature when expanding freely and hairspray is not an ideal gas, hence it cools down.
Background courses are listed on the syllabus page of the OCW course site for informational purposes, but are not requirements for self-study using OCW materials. In this case, the background courses are 8.044 Elementary Statistical Mechanics and one of the following: 8.04, 8.05, and 8.06 which are Quantum Mechanics I, II, III respectively.
EL experimento de joules no es en un recinto aislado. It must be defined that it is an adiabatic isolation without involving the heat, otherwise it is a cyclic definition.
I had this class with Kardar back in '99. He's a brilliant professor. He never referred to notes while lecturing; he had it all in his head.
Me in '91. It is the same class. Never saw a question he did not address clearly & intelligently.

Dear sir,
What is the difference between
5.60 Thermodynamics & Kinetics (chemistry) and 8.333 (physics) Statistical Mechanics of Particles lectures.
Are they same, or learning the same thing from different perspective of physics and chemistry.
Starts @ 23:00 the first 23 minutes are admin and waffle, nothing to do with thermodynamics

Yes, this course is a graduate level class.
CrushOfSiel Classes on the same topic can have varying levels of depth and requisite background knowledge.
Why does equilibrium imply holonomic constraints?????
One way of seeing it is that the constraint shouldn't depend on the derivatives of the co-ordinates(since it is an equilibrium). Also, it obviously isn't any inequality.
Hey, I got a question. What are the coordinates of these functions? Means what theese functions are actually representing? Real physical meaning?
They are some sort of variables like p v n T etc, he uses ideas from vector spaces
The first law of thermodynamics is that there can not be a zero temperature measured by human or mechanical but that does not mean either it exist or it does not zero because it has zero frequency meaning it has no dimension like consciousness
Second law is that in an only in an isolated system can have work done but as a universal system zero sum is resulted meaning a whole universe can only transform but never had more or less in total energy or matter as a total sum
Third law is that the entropy of the whole universe always increase meaning all would disintegrated into lighter material and consciousness will be a disconnected for rather than in solid line of metal or rock. Therefore quantum mechanic is a ultimate evolution not a avoidable state.

In short, experiments show that gases that are well described by the ideal gas model don’t change temperature when expanding freely and hairspray is not an ideal gas, hence it cools down.
Gracias.❤️
So he is mehran kardar
Brilliant!
Blimey - this sort of nonsense sends my brain completely around the bend .
What are the prerequisites for the course?
Background courses are listed on the syllabus page of the OCW course site for informational purposes, but are not requirements for self-study using OCW materials. In this case, the background courses are 8.044 Elementary Statistical Mechanics and one of the following: 8.04, 8.05, and 8.06 which are Quantum Mechanics I, II, III respectively.
Sir which book you have preferred for this

Man. No grading on a curve?..brutal.
When I make fart, the heat travels forward. So really. Farts are an example of thermodynamics
Questions those asked by students are not audible.
thanks
blow air onto a heat sink, is thermodynamics through and through.
EL experimento de joules no es en un recinto aislado. It must be defined that it is an adiabatic isolation without involving the heat, otherwise it is a cyclic definition.
He is cleaning chalkboard with dry sponge... I think you should not do It, because you release chalk dust into the air, thus not clean air
thank u so much
