Using a plot of average speed in meters per second against the logarithm of the distance, he drew a graph of 17 record marks, from 200 meters to 10 miles.

He was always trying to teach me the logarithm table he knew by heart, and infinitesimal calculus.

The theory is simpler than rolling off a logarithm: set a small square within a larger one and, instead of living in the middle with a garden all around, live all around and put .

Math Advance Suggest RSA Encryption Could Fall Within 5 Years holy_calamity writes "The two encryption systems used to secure the most important connections and digital files could become useless within years, reports MIT Technology Review, due to progress towards solving the discrete logarithm problem. Both RSA and Diffie-Hellman encryption rely on there being no efficient algorithm for that problem, but French math professor Antoine Joux has published ...
