Keychain: Zernike polynomial Z(8,4) Key Ring
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. This magnet features the Zernike polynomial of order 8 and angular frequency 4, a complex valued function.

Premium Round Keychain, Large (5.397 cm)
These are a durable metal and the colors are vibrant. One of the clasp came broken but received a new one quickly. Customer service was responsive and quick to resolve the issue. They are bigger than I thought but still work for my wedding. I am satisfied with the print quality and surprised at how vibrant the colors are.
