Exploring problems. I've probed a few problems of interest with elementary ideas.

• The smooth arc problem is being written up

• Is 2^n root(2) mod 1 dense in [0,1]?

Talks.

• The Belt Trick and Spin Groups: notes coming soon         

Miscellaneous writing. Facts to bore your friends (and yourself)

• Exponential families (and the Gaussian dist.) are determined by a few points. 

• Verification of some details in Schwarz' original proof of the BIC
