About This Design

Euler's Formula Tie

Euler's Formula Tie

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). It's like 9-ball for smart people.

I originally ordered 1 tie to test and ensure I liked it with the suits we had ordered! The tie came and it was perfect! We loved it! The colours were bright and the tie was beautifully made. I then ordered the 6 additional ties and the colours are slightly different. The 6 ties were a little less vibrant and the white background was slightly different! .

This is an awesome German Flag tie ! The quality and the printing of this tie is perfect and is equal to what you see on the screen. I selected this tie because not only does it look 'rock'n'roll' the 'faded grungy' look goes perfect with my 'metal rockstar' look. The printing on the tie is perfect. 10 out of 10.
