In two issues of Math in the News, we explore the math and physics behind the sinking and resurfacing of the Costa Concordia, which remained off the Italian coast for over a year. The impressive engineering feet of resurfacing the ship involved a clever solution, which we explore graphically.

In our current issue of Math in the News we look at Diana Nyad’s remarkable swim from Havana to Key West, Florida. We analyze the time and distance covered and use that as an opportunity to explore Average Speed.

Average Speed results in a linear function, and is useful for describing overall motion. But it’s not as useful for describing motion at specific locations and times. So, we analyze the data generated from Nyad’s swim relative to the Average Speed. This provides an excellent opportunity to see how disparate data points are smoothed out by the Average Speed function.
