Rated 5 out of 5 by from Very dense Simply put this course was very dense. I had to watch each episode several times to get the most out of it. I did this willingly, as it was worth it. The experiments connected to the discussions. I wish I could have more information in regards to the last lecture though. I hope it is in the notes.

Rated 5 out of 5 by from Outstanding I have bought several courses from your company. As old ChE with 2 degrees, I just wish I had Dr Grossman back in Engineering school. Absolutely wonderful. Exciting, straightforward, clever demonstrations, enthusiastic presenter. So many hours of mental pain I could have saved. Course is good for undergraduates, graduates plus experienced engineers. Fun learning.

Rated 5 out of 5 by from Thermodynamics: energy in nature This course provides an intuitive understanding of the fundamentals of energy conservation, transfer and directional reactions in nature. This understanding is backed by some simple lab experiments to illustrate the impact of energy transfers on materials. The course, to its credit, is not shy of calling mathematics to establish the relationships between internal internal energy, work and heat further used in the definition of entropy. I measure the quality of a course to the stimulation of observation and thinking it induces in me, and it does it a lot !

Rated 5 out of 5 by from Very complete and very relevant I have taught thermodynamics for university chemistry majors for a number of years and I still learned new things from this course. The emphasis on phase diagrams is very appropriate and helps make the link between thermodynamics and modern materials. Dr. Grossman is a materials scientist and as such brings a unique focus to this topic.

Rated 5 out of 5 by from Great Course; good lab experiments This was a great course that filled in many gaps in my knowledge of physics. Dr. Grossman had many entertaining and helpful experiments to embellish his very polished lectures. I greatly enjoyed this course!

Rated 5 out of 5 by from Demo maniac! (In a good way) Lots of fun watching most of the lectures, with the critical eye of an old thermo instructor. I used to like giving demos to lighten the mood, and Grossman is at his best doing this. I particularly liked the green eggs. One can always quibble, but this is about as interesting as it is possible to make introductory thermodynamics.

Rated 5 out of 5 by from Great great experiments I was doing this as a refresher and also because I was never clear on thermodynamics. Enthalpy, Gibb’s energetic were always just combinations of variables, never clear why they were needed. This course really gave me the gut feel for all that. Really enjoyed the experiments. This lecturer takes care to explain the fundamentals. I am so glad he used math. Once cannot explain the depth without math, anyone taking these courses will know math so use it!! I guess Great courses is now allowing math? I only wish that the equations and some concepts were included in the booklet.

Thermodynamics is the branch of science that deals with the movement of heat. Nothing seems simpler, but nothing is more subtle and wide-ranging in its effects. And nothing has had a more profound impact on the development of modern civilization. Thermodynamics: Four Laws That Move the Universe gives you an in-depth tour of this vital and fascinating science in 24 enthralling lectures that are suitable for everyone from science novices to experts who wish to review elementary concepts and formulas. Your teacher is Professor Jeffrey C. Grossman of the Massachusetts Institute of Technology, a scientist at the forefront of research on new materials.


Jeffrey C. Grossman

The Sun is the opposite of a laser. If it were a laser, we'd have an easier time making solar cells because we could tailor our converters of light energy to one specific wavelength.


Massachusetts Institute of Technology

Dr. Jeffrey C. Grossman is Professor in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology (MIT). He earned his B.A. in Physics from Johns Hopkins University and his M.S. in Physics and his Ph.D. in Theoretical Physics from the University of Illinois at Urbana-Champaign. Before joining MIT, Professor Grossman founded and headed the Computational Nanoscience research group at the University of California, Berkeley, which focused on designing new materials for energy applications. At MIT, he heads a research group devoted to understanding, predicting, and designing novel materials with applications in energy conversion, energy storage, and thermal transport. As a Lawrence Fellow at the Lawrence Livermore National Laboratory, he received the Physics Directorate Outstanding Science and Technology Achievement Award. He was also awarded a coveted Sloan Fellowship soon after joining MIT. Professor Grossman's current research centers on the development of new solar thermal fuels, the design of nano-scale technologies for sequencing DNA in hours, three-dimensional photovoltaic panels, new materials to convert waste heat into electricity, and more. He has also developed entirely new ways to encourage idea generation and creativity in interdisciplinary science, including 'speedstorming,' a method of pair-wise idea generation that works similarly to a round-robin 'speed-dating' technique.
