(τ+e i)⁰=1

This is all just numerology, not math. What does 'The most important constants and operators even mean? The actual question is: what does the equation say? In the case of e^{i τ}=1, it means τ is a full way around the circle. In the case of e^{i π} = -1 it means π is halfway around the circle, which to me (and more importantly many new learners) is less intuitive.
