About This Design
Button: Zernike polynomial Z(8,8) Pinback Button
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 8, the only analytic polynomial of 8th order.

I love the quality and the color and the design I got to customize them to the way I like my husband and I are different and it was really nice that I could custom mama instead of mommy or mom because I like to be called mama so that was nice and then I was able to make his big sisters to buttons as well so that was really nice. I love the design it’s simple it’s cute I can’t wait to wear them on my baby shower day.

Round Button, Standard, 2¼ Inch
The button was just as expected. My mother's smile was captured so beautifully. The size was just right and the colors we chose were bright. The print was nice and clear. A person ordering should just make sure the wording is lined up in the center before submitting
