The Englishman says " I was cleaning my daughter's room the other day & I found a packet of cigarettes. I was really shocked as I didn't even know she smokes".

The Scotsman says " That's nothing. I was cleaning my daughter's room the other day when I came across a half full bottle of Vodka. I was really shocked as I didn't even know she drank."

Neil Kensington Adam

Born 5 Nov 1891; died 1973 .English physical chemist who continued Langmuir's work of 1917 on surface films. During WW I, he served as a chemist in the Royal Naval Airship Service. Adam's work on unimolecular films on water (1920-39) showed that at the water-air interface there existed a two-dimensional state of matter and that this could exist in various phases. (Compare how in three dimensions there exist various phases: solid, liquid and gaseous states). This led to improved understanding of the shapes, sizes and fields of force surrounding organic molecules. He also studied surface active agents and detergents. Among other papers, Adam wrote The Physics and Chemistry of Surfaces.[Image: At an air-water interface lipids will form monolayers with the polar head groups directed towards the water the fatty acid chains exposed to the air.]
