Happy Pi Day!

3/14/15 9:26:53

Engineers love March 14, since the digits represent the value of Pi. We use Pi in all sorts of calculations here on the boat and for the robotics things that I build.

There are lots of radio calculations that use Pi, without Pi your cell phone (or marine VHF radio) wouldn’t work. Don’t even think about trying to get a GPS position without using Pi.

This year is special 3 / 14 / 15 is the first part of Pi: 3.1415 and this morning is a few extra digits to give you 3.141592653. For most things 4 decimal places (3.1415) lets us gauge things like the circumference of the earth to a few miles. The more precise 3.141592 gets you to within a mile of the moon. 3.141592653 puts you right on Mars.

So remember anything that is engineered most likely had Pi as part of it engineering math!

Happy Pi day (and feel free to celebrate by having a slice of Key Lime!)
