Pi Day (March 14, or 3/14) gets a lot of play in the U.S., but doesn’t work in other countries that write dates as DD/MM/YYYY, so it becomes 14/3. An alternative in those areas is e day, after the base of natural logarithms, e, (2.71) on 27 January. So, we’re going to avoid the Pi Day rush and post some math cartoons today.

Like pi, e shows up in a variety of places in mathematics, and is associated with some of the greats in mathematical development. From Wikipedia:

“The number e is sometimes called Euler’s number …—after the Swiss mathematician Leonhard Euler —or Napier’s constant—after John Napier. The constant was discovered by the Swiss mathematician Jacob Bernoulli while studying compound interest.”

Some fuzzy math from websites. The first is from Kiva.org.

This one is from MyVirtualMission.com, a site where you can virtually pretend to climb Everest or complete the Camino de Santiago as you run/walk/bike around your neighborhood. Somehow, their counter of missions (trips) has gone awry. Or maybe I did one backwards?
