Today is Pi Day (March 14th = 3.14) however here are two reasons why we not only shouldn’t mark Pi with a day of its own but also we just shouldn’t use Pi !!
This video makes a very good argument for the use of Tau rather than Pi (or 2Pi to be exact). However I have an even stronger argument for not using Pi.
Choose a lifestyle that doesn’t involve Pi, Tau, SohCahToa, or any other of the maths ‘they’ made you learn at School and Uni. It has worked for me for a long time now.. I’m happy that some people know and use this stuff just as long as it doesn’t have to be me.
