To Do List

When I returned home from college for a break, I noticed a paper posted on the refrigerator. It listed some goals my dad had set for himself: Help wife more; lose weight; be more productive at work.

I promptly added: “Send Michelle money every month.”

A few days later my brother wrote: “Make payments on car for Jason.”

Then my boyfriend joined in with: “Buy Tom a Jeep.”

Finally my father added a new goal to his amended list: “Wean kids.”

Odd Hassel

Died 11 May 1981 at age 83 (born 17 May 1897).Norwegian physical chemist who shared (with Sir Derek H.R. Barton of Great Britain) the 1969 Nobel Prize for Chemistry for his work in establishing conformational analysis (the study of the 3-D geometric structure of molecules). A ring of six carbon atoms has two conformations - the chair and boat forms. These easily interchange - about a million times in a second at room temperature. One of the conformations is, however, strongly predominant (about 99%). Hassel carried out fundamental investigations on this system and showed how heavy or bulky groups, attached to the carbon atoms, take up their positions relative to the ring and to each other. Such work is of great importance for predicting the mode of reaction of a certain molecule.
