The Euler formula Keychain
Show your love of math and your appreciation for your math education with this subtly tasteful mousepad. Euler's identity involves the special numbers 0 and 1 and relates the transcendental numbers e and pi to integers. This stems from Euler's identity which itself is a consequence of the Taylor series representations. A perfect gift for your favourite polymath, a dear friend or yourself.
