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

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:
Matt Ridley: Cooling Down the Fears of Climate Change
In The Wall Street Journal, Matt Ridley reports that the latest scientific evidence points to a further rise of just 1°C by 2100-and the net effect on the planet may actually be beneficial.
Fascinating article about the neuroscience of music, from National Geographic…
Earth at Night – Photo Journal – WSJ.
New satellite images from NASA show what the Earth looks like at night – pretty awesome!
My good friend Larry Linenschmidt has organized the “Vibrant Dance of Faith and Science” Symposium, which is scheduled to take place October 26–28 in Austin, TX. Larry is executive director for the Hill Country Institute for Contemporary Christianity, and he has succeeded in putting together a very impressive roster of speakers, including (among others) my Baylor colleague Walter Bradley!
For more information about the Symposium, visit the website at vibrantdance.org. In closing, here’s Larry himself describing the Symposium in his own words:
Here’s a list of articles that I have been reading lately:
“British Prime Minister David Cameron writes in The Wall Street Journal that the U.S. and Britain have a clear common agenda: succeeding in Afghanistan, securing economic growth and fighting protectionism.”

Leeds: Chew on this: There is no surplus fairy for Social Security
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.””
Economics One: New Data Show the Debt Problem Is Spending (not Taxes) and Obamacare Worsens the Problem
Quoting from Stanford Professor John Taylor’s Blog (Economics One): “Everyone now seems to agree that the exploding federal debt is a serious problem that must be addressed. But how? The following … charts provide some data to help answer that question.”
“A Wall Street Journal editorial says the global warming alarmists still won’t separate science from politics.”
Here’s what we have to look forward to as Obamacare starts to come “on line” (Massachusetts passed so-called Romneycare in 2006, and Obamacare structurally closely resembles Romneycare, only on a national as opposed to individual state level)… “The relentlessly rising cost of health insurance is prompting some small Massachusetts companies to drop coverage for their workers and encourage them to sign up for state-subsidized care instead, a trend that, some analysts say, could eventually weigh heavily on the state’s already-stressed budgets”.

“In The Wall Street Journal Heritage Foundation fellow Brian Riedl explains that runaway government spending, not declining tax revenues, is the reason the U.S. faces dramatic budget shortfalls for years to come.”
Economics Nobel laureate Gary Becker’s take on the financial-reform bill; he particularly dislikes the facts that this bill 1) adds regulations and rules about many activities that had little or nothing to do with the (financial) crisis, and 2) essentially says nothing about Freddie Mac or Fannie Mae.

Fund Track: Collar Fund Offers Low Risk, Low Reward – WSJ.com
“A cautiously bullish strategy is the mainstay of the $31 million Collar Fund, whose portfolio has low enough risk to inspire comparisons to a bond fund, but whose hedged exposure to stocks aim for stronger returns than bonds.” The Collar Fund represents an interesting application of some very simple financial engineering; this is the sort of stuff we study in my “Options, Futures and Other Derivatives” course at Baylor University…”
