Page "Eccentricity (behavior)" Paragraph 7

Another famous eccentric was renowned theoretical physicist Albert Einstein ; his eccentricities included picking up discarded cigarette butts off the street in order to circumvent his doctor's ban on buying tobacco for his pipe, piloting his sailboat on windless days (" for the challenge "), and lecturing his 8-year-old nephew on physics ( including a 2-hour exposition on the Newtonian properties of soap bubbles ).
