* The late Marxist philosopher Gerry Cohen gives a spirited defense of what he calls conservatism about value. Video presentation here. Transhumanists in particular (and sympathizers, like me) will find a lot of stuff here with which they could fruitfully engage.

I can pick up a mole (animal) and throw it. Anything I can throw weighs one pound. One pound is one kilogram. The number 602,214,129,000,000,000,000,000 looks about twice as long as a trillion, which means it’s about a trillion trillion... if anyone asks, I did not tell you it was ok to do math like this.* Mark Galeotti, an expert on Russian politics and on organized crime, writes an excellent Russia-watching blog called In Moscow’s Shadows. Here is an entry that speaks to issues important to skeptic types.
* The Economist reviews Ben Goldacre’s new book, Bad Pharma (on my reading list). The fact that Goldacre has written extensively before criticizing various forms of alternative medicine does not hurt his credibility here.
* You all know about Khan Academy, right? Because that is some seriously low-hanging utility.
* Speaking of which, GiveWell discusses their evolving criteria for charity evaluation.
* And now, some levity: Kate Evans’ (aka @aristosophy) witty and erudite twitter feed.
