Little Johnny on Math
A teacher asks her class, "If there are 5 birds sitting on a fence and you shoot one of them, how many will be left?" She calls on little Johnny.
He replies, "None, they will all fly away with the first gunshot."
The teacher replies, "The correct answer is 4, but I like your thinking."
Then little Johhny says, "I have a question for YOU. There are 3 women sitting on a bench having ice cream: One is delicately licking the sides of the triple scoop of ice cream. The second is gobbling down the top and sucking the cone. The third is biting off the top of the ice cream. Which one is married?"
The teacher, blushing a great deal, replied, "Well, I suppose the one that's gobbled down the top and sucked the cone."
To which Little Johnny replied, "The correct answer is 'the one with the wedding ring on', but I like your thinking."
James Prescott JouleBorn 24 Dec 1818; died 11 Oct 1889 at age 70. English physicist who established that the various forms of energy - mechanical, electrical, and heat - are basically the same and can be changed, one into another. Thus he formed the basis of the law of conservation of energy, the first law of thermodynamics. He discovered (1840) the relationship between electric current, resistance, and the amount of heat produced. In 1849 he devised the kinetic theory of gases, and a year later announced the mechanical equivalent of heat. Later, with William Thomson (Lord Kelvin), he discovered the Joule-Thomson effect. The SI unit of energy or work , the joule (symbol J), is named after him. It is defined as the work done when a force of 1 newton moves a distance of 1 metre in the direction of the force.
