Biomes are too dynamic and intertwingled to be managed with simple political slogans: The case of Gnetum luofuense

Corners of the Environmentalist Establishment voice shrieks regarding what they call a biodiversity emergency, prompting even skilled journalists to claim the trend poses “as great a risk to humanity as climate change.” We went through the “insect apocalypse” fiasco, which … Continue reading

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

Really interesting mechanistic reductionism illustrating what it means to explain phenomena scientifically. It’s all about the maths.

“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
