Complicated order

A resident in a seaside hotel breakfast room called the head waiter to his table. "I want two boiled eggs, one of them so undercooked it's runny, and the other so overcooked, it's tough and hard to eat. Also, give me some grilled bacon that has been left on the plate to get cold; burnt toast that crumbles away as soon as you touch it with a knife; butter straight from the deep freeze so that it's impossible to spread; and a pot of very weak coffee, luke-warm."

"That's a complicated order, Sir," said the bewildered waiter. "It might be quite difficult to prepare."

The guest replied, "Oh? But that's what I got yesterday!!"

John Dollond

Born 10 Jun 1706; died 30 Nov 1761 at age 55.English optical instrument maker of optical and astronomical instruments who developed (1758) and patented an achromatic (non- colour- distorting) refracting telescope and a practical heliometer, a telescope used to measure the Sun's diameter and the angles between celestial bodies. In the 1730's, Chester More Hall, an attorney with an interest in telescopes, first discovered that flint glass appeared to have a greater color dispersion than crown glass did at the same magnifications. Hall reasoned that if he cemented the concave face of a flint glass lens to the convex face of a crown glass lens, he could remove the dispersion properties (and thus, chromatic aberration) from both lenses simultaneously. Dollond learned of the technique in the 1750's and developed it.
