You’re in Charge of...

An Italian, an Irishman and a Chinese fellow are hired at a construction site. The manager points out a huge pile of sand and says to the Italian, "You're in charge of sweeping". To the Irishman, "You're in charge of shoveling" To the Chinese guy, "And you're in charge of supplies". "Now, I have to leave for a little while. I expect you guys to make a dent in that pile."

So the manager goes away for a couple of hours. And when he returns, the pile of sand is untouched. He says to the Italian, "Why didn't you sweep any of it?

The Italian guy replies, "I didn't have a broom. You said the Chinese guy was in charge of the supplies, but he disappeared and I couldn't find him" So then the manager turns to the Irishman and asks why he didn't shovel.

The Irishman replies, "I couldn't get myself a shovel. You left the Chinese guy in charge of supplies and I couldn't find him." The manager is really pissed now, and storms off toward the pile of Sand looking for the Chinese guy.

Just then, the Chinese guy springs out from behind the pile of sand and yells, "SUPPLIES!"

Ronald G.W. Norrish

Born 9 Nov 1897; died 7 Jun 1978 at age 80.Ronald George Wreyford Norrish was a British chemist who shared the 1967 Nobel Prize for Chemistry with fellow Englishman Sir George Porter and German Manfred Eigen for their studies of very fast chemical reactions. From 1949-65 he collaborated with his former pupil George Porter in the development of flash photolysis and kinetic spectroscopy for the investigation of very fast reactions. Norrish also made a significant contribution to chemistry when he corrected Draper's law. In the mid-19th century John Draper proposed that the amount of photochemical change is proportional to the intensity of the light multiplied by the time for which it acts. Norrish showed that the rate was in fact proportional to the square root of the light intensity.
