Intuitionistic mathematics for physics

Andrej Bauer (mathematician, computer scientist, and old friend from Carnegie Mellon) has an interesting post on why he thinks intutionistic mathematics is good for physics (HTs to Brian Weatherson and Greg Restall).

Random numbers (for free)

Prompted by a nice discussion that Horacio and I had concerning a possible experiment, I did some looking around for random number generators and stumbled upon this site that uses atmospheric noise as a source of randomness. The basic services on the site are free, but they do offer a premium generator. I'm not sure about the true randomness claims on the site, and I suppose that more pedestrian sources abound (e.g. perhaps variation in the time interval between successive beats of your heart), but the site is worth a look.
