How much of this was a consequence of having separate categories of fuel efficiency regulations for "passenger cars" vs "light duty trucks" (including pickups and SUVs) incentivizing a growth in market share for the latt

Thanks! Anyway, I'll try to think about ways to help my writing be more approachable for an international audience in my next articles. And regardless, I really enjoyed your comments. Cheers!

The RHP0 in (Canadian) housing comes from including mortgage interest payments -- a term that increases in proportion to interest rates -- in the measurement of the CPI.

That would be a right-half-plane pole. An explanation of the Laplace transform is coming! This is an article, not a book.

Fair. Perhaps a glider would have been a better example.

They are certainly something that your MPC controller will need to account for, and they will constrain the theoretical maximum performance you can get out of the system no matter how optimal your control algorithm is.

Thank you for reading! I agree the Earth is a much worthier system to be worried about than the economy, for sure.

To add to this comment, it's hard to make any useful program if you don't have at least a clear conceptual understanding of what you're trying to do. For example, perhaps you are trying to calculate a variance. But do you hav

We're coming up on 500 years of Thomas Tallis, a composer whose works are still popular and frequently performed. I would guess that if there are still humans around in 300 years, they will still be discussing Beethoven.
