From steam to entropy: Creating a thermodynamics tour through Europe (and Yale)
I need your input on this. A friend of mine asked, “Bob, how about creating a European tour featuring the different locations where the founders of thermodynamics worked, including opportunities to taste the local beers?” I responded, “Great idea!” So what would that tour look like? Here’s a very rough outline based on chronological sequencing:… Continue reading

For every effect, there must be a cause
The 1st Law of Thermodynamics is all about energy and its conservation. In 1850 Rudolf Clausius put it into an equation by conducting an energy balance around the working substance inside a piston. ∆U = Q - W The change in internal energy of a system (U) is equal to the heat (Q) entering the system minus the work (… Continue reading

Fourier solved heat. Or did he?
Thermodynamics began when caloric ended A pivotal event in thermodynamic history occurred when Julius Robert Mayer and James Joule independently overthrew the caloric theory of heat, revealing heat and work as two forms of energy. In 1850 Rudolf Clausius used these findings to correct the single flaw in Sadi Carnot’s 1824 theoretical analysis of the… Continue reading

About Me
Hi! I’m Bob Hanlon. After earning my Sc.D. in chemical engineering from the Massachusetts Institute of Technology and enjoying a long career in both industry and academia, I’ve returned to school, my own self-guided school, seeking to better understand the world of thermodynamics. Please join me on my journey.
