Borbin the 🐱

It was in one of my first physics courses that the professor used 22/7 in an equation as an approximation. Within a few steps, he calculated the result on the board, leaving us impressed.

So simple, and yet so close:

$$\frac{22}{7} = 3.\overline{142857}$$

$$\pi = 3.14159265358\ldots$$

$$\frac{22}{7} - \pi \approx 0.00126$$

The math department would not have approved, but we engineers were perfectly fine with it!
