Euler's Formula Tote Bag

While those around you play out the insignificant comings and goings of their daily lives, you will be smirking on the inside, secure in the secret knowledge that the colourful symbols on your LabKitty Euler's Formula item are no mere random collection, but rather spell out (when arranged in appropriate order) Euler's identity: exp(i*theta) = cos(theta) + i * sin(theta) for theta = pi. Called the most beautiful formula in all of mathematics by no less than famous Los Alamos / QED / Challenger Investigation physicist and nerd hero [ redacted ], the formula combines the two most important integers (0 and 1), the two most important irrational numbers (pi and e), the basis of the complex number system (i), and the four fundamental mathematical operations (addition, multiplication, exponentiation, and equality). Put them all together and they spell awesome!
