Giulio Natta

Born 26 Feb 1903; died 2 May 1979 at age 76.Italian chemist who contributed to the development of high polymers useful in the manufacture of films, plastics, fibres, and synthetic rubber. Along with Karl Ziegler of Germany, he was honoured in 1963 with the Nobel Prize for Chemistry for the development of Ziegler-Natta catalysts. Natta found that certain types of Ziegler catalysts lead to macromolecules with a spatially uniform structure, called isotactic chains. Whereas ordinary hydrocarbon chains are zigzaged, isotactic chains form helices with the side groups pointing outwards. Such polymers give rise to novel synthetic products. Examples are light but strong fabrics, and ropes which float on the water.

Joe and Joan were sitting down to their usual morning cup of coffee listening to the weather report on the radio. "There will be 3 to 5 inches of snow today, and a snow emergency has been declared," the weather report said.

"You must park your cars on the odd numbered side of the streets."

Joe said, "Jeez, okay," and got up from his coffee.

The next day they were sitting down with their morning cups of coffee. The weather forecast was, "There will be 2 to 4 inches of snow today, and a snow emergency has been declared.

You must park your cars on the even numbered side of the streets." Again Joe replied, "Jeez, okay," and got up from his coffee.

Two days later, again they're sitting down with their cups of coffee and the weather forecast said, "There will be 6 to 8 inches of snow today, and a snow emergency has been declared. You must park your cars on the..." and the power went out and Joe didn't get the rest of the instructions.

He turned to Joan, "Jeez, what am I going to do now, Joan?"

Joan replied, "Aw, Joe, just leave the car in the darned garage today."
