In a way it's analogous to how Einstein's E = mc^2 is a special case of how the norm of the four-momentum is defined in special relativity, which is mc = √((E/c)^2-p^2). For the special case of a stationary object we have p = 0, so E = mc^2 follows automatically. But the special case is somehow more memorable and more famous, and I believe something similar has happened with Euler's identity. |
