What is Energy?
Although energy is one of the most fundamental concepts in physics, it is an elusive beast that is difficult to pin down.

Energy Transfers
The objective of this essay is to outline the types of energy transfers that occur in thermodynamics, namely, work, heat and mass transport.

Spreading & Irreversibility
Spreading is a phenomenon that is very familiar to us. It is detectable by humans when they smell good or bad things in the air …

Power & Reversibility
Time plays no role in much of thermodynamics as it is typically taught in physics and chemistry classes … In real-life processes, the situation is very different …

Cycles & Clausius
This is a thumbnail sketch of Clausius' thermodynamics accomplishments …
