About This Design
Zernike polynomials - ascending tie
In 1933, Nobel Laureate Frits Zernike published a set of orthogonal polynomials designed to span the unit disc for the purpose of describing the aberrations of a circular mirror. Today these same polynomials are used to codify the imperfections in optical systems such as telescopes. Ophthalmologists and optometrists use them in wavefront guided vision correction. Whether or not you work in Hilbert space or fancy orthogonal polynomials and special functions, this tie shows your appreciation for mathematics and science.

That's exactly what I was expecting! I made a custom design and it looks so good. I will definitely recommend this shop and service for my friends. Good quality. Exactly like in the photo.

The tie was shown as being black and white on the website but unfortunately it is green and white once I received it. This is false advertisement and I am reporting it. I want my money back. I'm willing to return the tie. It's no good. .

I was beyond thrilled with how this custom tie turned out. I applied my husband’s business name to it all over the place and it was beautifully produced, absolutely perfect. Silky, shiny, exactly as I designed it. The lettering was not raised which was my fear. It formed a part of the tie itself so it looked like it was supposed to be there! My husband loved it and I made 9 more in different designs. Produced very quickly, well packaged and arrived early! I loved this design so much and the print turned out so nice, exactly as I designed it and it was not raised, it looked as though it was part of the overall fabric itself! It was so cool!
