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.

A little girl was out with her...

A little girl was out with her Grandmother when they came across a couple of dogs mating on the sidewalk."What are they doing, Grandma?" asked the little girl.
The grandmother was embarrassed, so she said, "The dog on top has hurt his paw, and the one underneath is carrying him to the doctor."
"They're just like people, aren't they Grandma?" said the little one.
"How do you mean?" asked the Grandma.
"Offer someone a helping hand," said the little girl,"and they screw you every time!"
