Happy Tau Day

Forget about Pi Day, today we celebrate something twice as good: Tau Day. For far too long, Pi has been the bride and Tau has been the bridesmaid. As Michael Hartl points out in The Tau Manifesto, "Pi is a confusing and unnatural choice for the circle constant." He is giving a talk at the California Institute of Technology based on the Manifesto, with pie served at the end. "Twice as many as you might expect," he says.

Re:Always show your work

[geekoid]

Then you teacher failed. Showing your work is about knowing the procedure to do something.

Even the dimmest child can look at: 4 * X = 8 and KNOW X=2. But the real lesson is showing the work so when it's not that easy you can get a correct answer.
You use an easy example so when they finish going through the correct steps they can know they did it correctly.
