- Correlation between fat intake and brain-test scores. “Those women who reported the highest saturated fat intake also had, on average, the worst scores on reasoning and memory tests.”
- How many iPads does it take to change a textbook market? A perfectly good physics textbook is now available for free download (pdf). The author of the post, a physics professor at William and Mary named Marc Sher, does not understand what’s going on when he refers to “the textbook publishers’ price-gouging monopoly” and their “outrageous practices”. Textbooks cost so much because students can be forced to pay that much. This has nothing to do with publishers, I submit, and everything to do with the power professors have over students. Sher would reply: All the textbooks are expensive. And I say: So what? If students could choose not to buy $200 textbooks, none would be sold. Zero. And future years would see no more $200 textbooks.
