Complexity vs Simplicity in Geophysics

Posted on 10 November 2020 by ecoquant

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

Absorption of long wave, or thermal radiation by CO2 at 667 per cm

Posted on 28 May 2016 by ecoquant

From time to time, I engage with science deniers on the Web, typically in Comment sections, and primarily regarding aspects of climate science or physics. Some think this to be a waste of time, but, as I enjoy debating (have … Continue reading →

    I have used dlm almost exclusively, except when extreme efficiency was required. Since Jouni Helske's KFAS was rewritten, though, I'm increasingly drawn to it, because the noise sources it supports are more diverse than dlm's. KFAS uses the notation and approaches of Durbin, Koopman, and Harvey.

    ``The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.''
