My favorite graph of J. Willard Gibbs
To truly understand Gibbs’s groundbreaking 3rd paper on thermodynamics “On the Equilibrium of Heterogeneous Substances” (1875-1878), one should first read his first two papers (1872, 1873) to gain proper background and context. [1] Gibbs’ first two papers and the rise of graphical techniques There’s opportunity at interfaces. If you want to find a fertile field… Continue reading

Entropy – the known and the unknown
“I never understood entropy” – anonymous engineer Part IV of my book delves into the discovery and science of entropy. In this post, I explore what we know and question about entropy’s science, acknowledging my own unresolved inquiries. I’m open to learning, so if you have insights, references, or know someone who does, please share.… Continue reading

Gibbs free energy: G or ∆G?
One of my objectives in creating a more effective approach to teaching thermodynamics is to bring clarity to some of the confusing terms and concepts embedded in this field. Initially I focused on the concept of heat by pointing out that there is no such thing. I now turn toward free energy. As a very… 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.
