During a visit to the mental asylum, a visitor asked the Director how do you determine whether or not a patient should be institutionalised.
Well, said the Director, we fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub.
Oh, I understand, said the visitor.
A normal person would use the bucket because it's bigger than the spoon or the teacup.
No said the Director, A normal person would pull the plug out.
Do you want a bed near the window?

Mikhail Semyonovich Tswett

Died 26 Jun 1919 at age 47 (born 14 May 1872).Russian botanist, the “father of chromatography,” who developed and named the adsorption chromatography technique of separating plant pigments by extracting them from leaves with ether and alcohol and percolating the solution through a column of calcium carbonate. The components of the mixture moved at different rates, producing a series of bands. He is known in particular for his study of the chlorophylls and the carotenoids. However, in Tswett's own lifetime, chromatography remained virtually unrecognized as a scientific tool. In the 1930s, it was rediscovered and then spread worldwide. The chromatography technique he invented is now widely used to separate substances from mixtures. (Also spelled Tsvet.)
