He was asked, "Property holder?"
Dan replied, "Yes, I am, Your Honor."
Then he was asked, "Married or single?"
Dan responded, "Married for twenty years, Your Honor."
Then the judge asked, "Formed or expressed an opinion?"
Dan stated with certainty, "Not in twenty years, Your Honor."

Achromatic lenses

In 1758, optician John Dolland, having created achromatic lenses, reported this to the Royal Society. Isaac Newton had described the blurring effect due to chromatic abberation, but could not solve the problem in simple lenses, which was important in the preparation of lenses for telescopes and microscopes. A concave face of a lens of flint glass (which has a greater color dispersion than crown glass) is cemented to a convex face of a crown glass lens. Thus the dispersion properties causing chromatic aberration are removed from both lenses simultaneously. Although Dollond patented the discovery of the achromatic lens in the mid-18th century, it is widely believed that he was not its inventor, but learned about it from lens maker George Bass.
