Originally aired on July 22, 2015 on PBS, the salvage of Costa Concordia. It is a fascinating documentary. It is an incredible story of engineering.
I read the news just today that James Stewart, the mathematician who authored books on Calculus, died on December 4th, 2014.
I took a look at my bookshelf and immediately found a Calculus Textbook that Stewart authored. Stewart was a violinist and that explains why his books feature violin on the cover.
