Secondly, there's a post about the "positive reviews" the book allegedly has had thus far. Harriman claims that there have been "more than a dozen", although he fails to mention actual sources for all but two: a very brief, rather lukewarm online-only review from the National Science Teachers Association, and more importantly, a rave review from the respected Physics Today journal by math professor at Ohio State U, Ulrich Gerlach (no link available, sorry). Gerlach describes Harriman's book as "brilliant" and "destined to be the fountainhead of future studies in the philosophy of science".
Wait a minute...did he just say "fountainhead"? Yep, you guessed it. So we google "Ulrich Gerlach Ayn Rand" and here's what we get: among other things, an example of what appears to be his work from 2005, which sources The Introduction to Objectivist Epistemology in footnotes, and comments on an Amazon review of Tara Smith's Objectivist work "Viable Values" which read like standard Ayn Rand Institute catechism. So it's pretty obvious Gerlach is in fact a True Believer of the same stripe as Harriman, which in turn makes the Physics Today review basically worthless.
Funnily enough, Harriman forgot to mention this.
