One of the non-economic weblog's I used to check regularly was the Political Theory Daily Review. Hardly an inspiring name, to be sure - but in fact it was an intellectual treasure trove of daily finds, ranging far wider than the name might suggest. Book reviews, interviews, academic papers, controversies big and small. Richer, more eclectic, more up-to-date and more lively than the better known Arts & Letters Daily.
The blog is no more, but its author, the hyperactive Alfredo Perez, now posts his daily gleanings on the front page of the journal BookForum. The main difference is that they are now grouped thematically. Here is an example of a recent post:
A review of The Story of Measurement by Andrew Robinson. The first chapter from Benjamin Franklin's Numbers: An Unsung Mathematical Odyssey by Paul C. Pasles. A review of Perfect Figures: The Lore of Numbers by Bunny Crumpacker. Good stories, good math: Young children who show sophisticated story-telling skills go on to demonstrate greater mathematical ability. Alexis Lemaire can calculate the 13th root of a 200-digit number in just over a minute. In fact, he could be the greatest "mathlete" ever, but why does he want to spend four hours a day practising, and what's so special about 37? A review of Super Crunchers: Why Thinking-by-Numbers Is the New Way to Be Smart by Ian Ayres. A video that's worth a million words: Award-winning video reveals the simplicity and beauty of an abstract mathematical tool.
