Happenings – 2012 Dec 29
Updated: 2012-12-29 16:24:38Christmas vacation continues. I was away from home over Xmas, from the Saturday afternoon before until the Wednesday evening afterwards… I visited an old friend in Sedona AZ, driving there in two cars with two other friends, but returning alone. It amounted to 500 miles of my driving on Sunday, and 750 on Wednesday. Whew! [...]More podcasts coming up in 2013

In 2012 I began my podcast interview series, Inspired By Math!, where I interview people who are inspired by Math and who are inspiring others. I started the series with Keith Devlin on Valentine's Day and have published 15 podcasts altogether, including one with Michael Schrenk on Webbots, Spiders, and Screen Scrapers which was not [...]Happenings – 2012 Dec 22

Dr. Alfred Posamentier and Ingmar Lehmann recently co-authored a delightful book, The Secrets of Triangles: A Mathematical Journey, published by Prometheus Books. I had the pleasure of interviewing Dr. Posamentier for 50 minutes. Aside from the fact that we both grew up in New York City and got to reminisce about some of the prominent [...]Happenings – 2012 Dec 15
Updated: 2012-12-15 17:27:37There’s not a lot to talk about today. Most of my free time this week went toward the Coursera class on computational investing… as I said before, the instructor didn’t manage to deliver all that he had hoped… but it forced me to look elsewhere for the CAPM (Capital Asset Pricing Model), and it introduced [...]7th grade math test
