### Homework

A little boy was doing his math homework. He said to himself,
"Two plus five, that son of a bitch is seven. Three plus six, that son of a bitch is nine...."
His mother heard what he was saying and gasped, "What are you doing?"
The little boy answered, "I'm doing my math homework, Mum."
"And this is how your teacher taught you to do it?" the mother asked
Infuriated, the mother asked the teacher the next day, "What are you teaching my son in math?"
The teacher replied, "Right now, we are learning addition."
The mother asked, "And are you teaching them to say two plus two, that son of a bitch is four?"
After the teacher stopped laughing, she answered, "What I taught them was, two plus two, THE SUM OF WHICH, is four."

### Henry Horatio Dixon

Born 19 May 1869; died 20 Dec 1953 at age 84.Irish botanist who, with John Joly, investigated plant transpiration and originated the tension theory of sap ascent in trees (1894) building on the work of Eduard Strasburger, François Donny and Berthelot. Dixon's earlier work was in cytology and had developed sterile culture methods for seedlings (1892). After the 1894 publication, he made further transpiration experiments to consolidate his theory which he published in 1909 and 1914. He resolved the debate over the mechanism of xylem transport by proposing a compromise between the pulling power of the leaf and the tensile strength of the water columns. From 1910, he was curator of a new herbarium at Trinity College Dublin.«
