Postcard: Zernike polynomial Z(8,4) white back Postcard
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 postcard features the Zernike polynomial of order 8 and angular frequency 4, a complex valued function..

Exactly what I wanted, it is very difficult to acquire Vintage Australiana items. I am so please that I ordered 8 I will be using them for my scrap booking and Junk Journaling. Gorgeous, Zazzle produced and delivered exactly what I wanted.

Way better quality than I ever expected. I love the colours, font and quality of the card. I'm so pleased I found Zazzle as it is near impossible to purchase Vintage or Retro Australian memorabilia online. I chose this design when I purchased them. They are perfect for my projects. I was very specific about what I wanted. I know where to come now when I need to order similar items.

Perfect for the occasion I was using it for.
I was able to delete the lines so I could put in more wording.
Had an envelope so the address side wasn't necessary. Print quality and paper quality lovely.
