Derek Zoolander, spherical cows, the Guardian, and econophysics

Wonderful explanation of the logical fallacy associated with dismissing theories based upon modeling assumptions that are not literally true… HT to Scott Cunningham.

In Zoolander, the titular character is presented with a model of a building.  He inspects the model and responds with anger and indignation:

Derek Zoolander: What is this? [smashes the model for the reading center] A center for ants?

Mugatu: What?

Derek Zoolander: How can we be expected to teach children to learn how to read… if they can’t even fit inside the building?

Art meets chemistry meets physics meets finance

This Wired Magazine article provides a layman’s explanation of reaction-diffusion processes, which are characterized by reactive molecules that can diffuse between cells. A special case of a reaction-diffusion process is a “pure” diffusion process, where substances aren’t transformed into each other but nevertheless randomly spread out over a surface. While the reaction-diffusion process makes for much more aesthetically pleasing art, other so-called diffusion processes (e.g., diffusion of thermal energy as characterized by heat equations or movements of speculative asset prices as characterized by Itō diffusions) similarly generate (what appear to the naked eye to be) “patterns” from randomness…

Cooling Down the Fears of Climate Change

Matt Ridley writes the Mind and Matter column in The Wall Street Journal and has written on climate issues for various publications for 25 years. He is somewhat of a science polymath, having written on a wide variety of science topics – so many that he even has his own Amazon page @ http://amzn.to/V6Qn0E. His latest book, the Rational Optimist (cf. http://amzn.to/VPXE15), is on my reading list for the holidays. His latest WSJ article provides an interesting and informative assessment of empirical climate research:

Leeds: Chew on this: There is no surplus fairy for Social Security

www.statesman.com

Here’s the bottom line from Sandy Leeds’ editorial, published in today’s Austin American Statesman:

“The bottom line is that we’re in trouble. Social Security is woefully underfunded and Medicare is an even larger problem. This is going to increase the amount that we’re going to have to borrow from investors – and there’s no certainty that investors will always be willing to lend to us. Most importantly, we’re never going to solve these problems until the electorate understands the issues and starts to pressure our elected officials into making the hard (but right) decisions. We’re not doing anyone any favors by convincing them that we have “built up a big trust fund.””
