Baseload is an intellectual crutch for engineers and utility managers who cannot think dynamically

This is an awesome presentation by Professor Joshua Pearce of Michigan Technological University. (h/t Peter Sinclair’s Climate Denial Crock of the Week) The same idea, that “baseload is a shortcut for engineers who can’t think dynamically”, was similar in the … Continue reading

Complexity vs Simplicity in Geophysics

Originally posted on GeoEnergy Math:
In our book Mathematical GeoEnergy, several geophysical processes are modeled — from conventional tides to ENSO. Each model fits the data applying a concise physics-derived algorithm — the key being the algorithm’s conciseness but not…

“Ridiculously well-designed rockets”, not to mention some seriously awesome Mathematics

I’m just amazed with the quality of their controls systems, understated in the video, but which are absolutely critical to success. For more technical details, see: B. Açıkmeşe, J. M. Carson III, L. Blackmore, “Lossless convexification of nonconvex control bound … Continue reading
