Then, he disappeared for four years. His audience checked in periodically in the comments section but there was not much information to be had other than hints that he was still with us and might someday return.

His explanation of the prosaic aluminum beverage can and the 16-mm film projector are masterpieces – short stories as fine as any in written literature. He also did longer-form works including a book on the history of British airships.
But now, he has returned and one hopes to stay, examining the “engineering method” as he describes it. A complement to the much better-known scientific method.
In addition to the steam turbine below, he looks at cathedrals, turbulence, and revisits the microwave magnetron.
Welcome back, Professor.
