Use The Word

A pre-school teacher says to her class, "Who can use the word "definitely" in a sentence?"
First a little girl says, "The sky is definitely blue."
The teacher says, "Sorry, Amy, but the sky can also be grey or orange."
Then a little boy says, "Trees are definitely green."
"Sorry, but in the autumn the trees are brown."
Johnny from the back of the class stands up and asks, "Does a fart have lumps?"
The teacher looks horrified and says, "Johnny! Of course not!"
"OK. Then I have definitely shit my pants."

Sir J.J. Thomson

Born 18 Dec 1856; died 30 Aug 1940 at age 83. Joseph John Thomson was an English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted in 1908. Thomson experimented with currents of electricity inside empty glass tubes, investigating a long-standing puzzle known as “cathode rays.” His experiments prompted him to make a bold proposal: these mysterious rays are streams of particles much smaller than atoms. He called these particles “corpuscles,” and suggested that they might make up all of the matter in atoms. It was startling to imagine particles inside the atom at a time when most people thought that the atom was indivisible, the most fundamental unit of matter.
