Tau Stuff!

Perhaps from across the room on an early summer night, someone will notice your good taste and elegant evaluation of the circle constant. As they approach, they’ll say, “Happy Tau Day! Can I buy you a drink?”

Or, perhaps someone will see the strange symbol and ask whether it’s supposed to be a π (pi). Then you can explain all about τ (tau) and spread the Good News.

π is wrong. It’s time to set things right.

Here you can find beautiful jewelry which features the circle constant, τ.

We also have other stuff of scientific or mathematical interest.

We hope that you will enjoy these items and wear them with pride.

This website and all the items found here were imagined and created by Joseph Thiebes, student of physics and chemistry. Proceeds will help pay for books and ramen. Thank you!
