example of nearly-perfect image transmission through a fused-quartz sphere

Summary[edit]

One of the most perfect spheres ever created by humans. A fused quartz gyroscope for the Gravity Probe B experiment which differs from a perfect sphere by no more than a mere 40 atoms of thickness as it refracts the image of Albert Einstein in the background.
