Tau day 2026: Pi square is nearly 10

In the US and countries with a similar date format, today is the \(\tau\) day ( \(\tau = 2 \pi\) ). I still think that \(\tau r\) and \(\frac{\tau r^2}{2}\) are better formulas than \(2\pi r\) and \(\pi r^2\) , since they match the \(mv\) and \(\frac{mv^2}{2}\) ones (and many other reasons). But that ship has sailed, so \(\tau\) is relegating to just being the double of \(\pi\) . Well, addition is…
