I had been training as an artistic blacksmith since 2006 and after seeing the theodorus spiral (on page 33 of Paul’s book) I thought of the idea to make an iron shield in the shape of the spiral. I haven’t seen this proof. Each hypotenuse (longest side of the triangle) or spoke is always longer than the one before as the spiral goes around, but the difference in the change of length is getting smaller and smaller. to develop ideas that are refreshingly unexpected. and are encouraged to do what they love.
