Big Data’s Mathematical Mysteries – Ingrid Daubechies in Quanta magazine

Machine learning works spectacularly well, but mathematicians aren’t quite sure why.

” A pure mathematician, when stuck on the problem under study, often decides to narrow the problem further and so avoid the obstruction. An applied mathematician interprets being stuck as an indication that it is time to learn more mathematics and find better tools.”

Mathematical Impressions: Curved and Straight? – by George Hart

The elliptic hyperboloid is a beautiful quadratic surface that is “doubly ruled,” meaning that the surface, although curved, contains two straight lines through each point…Here it is applied to the design of a walk-through archway in the teaching garden at the University of British Columbia in Vancouver.”
