William Rutter Dawes

Born 19 Mar 1799; died 15 Feb 1868 at age 68.English amateur astronomer who set up a private observatory and made extensive measurements of binary stars and on 25 Nov 1850 discovered Saturn's inner Crepe Ring (independently of American William Bond). In 1864, he was the first to make an accurate map of Mars. He was called "Eagle-eyed Dawes" for the keenness of his sight with a telescope (though otherwise, he was very near-sighted). He devised a useful empirical formula by which the resolving power of a telescope - known as the Dawes limit - could be quickly determined. For a given telescope with an aperture of d cm, a double star of separation 11/d arcseconds or more can be resolved, that is, be visually recognized as two stars rather than one.«

Hair pulling

A six year old comes crying to his Mother because his little sister pulled his hair.

"Don't be angry," the Mother says, "Your little sister doesn't realize that pulling hair hurts."

A short while later, there's more crying, and the Mother goes to investigate.

This time the sister is bawling and her brother says...

"Now she knows."
