Who Is Calling?

The phone rang at the motor pool and an authoritative voice demanded to know how many vehicles were operational. Jim answered, ''We've got twelve trucks, ten utilities, three staff cars and that Bentley the fat-arsed colonel swanks around in.'' There was a stony silence for a second or two.
''Do you know who you are speaking to?''
''No,'' said Paddy.
''It is the so-called fat-arsed colonel you so insubordinately referred to.''
''Well, do you know who you are talking to?''
''No,'' roared the colonel.
''Well thank goodness for that,'' said Paddy as he hung up the phone.

Sir Derek H.R. Barton

Born 8 Sep 1918; died 16 Mar 1998 at age 79. Sir Derek Harold Richard Barton was an English chemist, a joint recipient (with Norwegian Odd Hassel) of the 1969 Nobel Prize for Chemistry for research that helped establish conformational analysis (the study of the 3-D geometric structure of complex molecules). In a brief paper in Experienta entitled “The Conformation of the Steroid Nucleus” (1950), Barton showed that organic molecules in general and steroid molecules in particular could be assigned a preferred conformation based on work of chemical physicists, in particular by Odd Hassel. Conformational analysis is useful in the elucidation of configuration, in the planning of organic synthesis, and in the analysis of reaction mechanisms. It is fundamental to a complete understanding of enzymatic processes.
