SUBJECT:            "Photochemistry Under the Sun", Sydney Chapman Memorial Lecture

LOCATION:         Pearl Berry Boyd Hall, Natural Sciences Facility, UAF Main Campus

DATE & TIME:     Friday, October 20, 7 p.m.

Professor Lord Porter, a Nobel Laureate in chemistry, is UAFís 1995 Sydney Chapman Memorial lecturer. He will give a free, public lecture Friday, Oct. 20 at 7 p.m.

Porterís area of expertise, photochemistry, is of primary importance in atmospheric chemical processes. It is the power behind photosynthesis, evolution and life on earth. Through human consumption of non-renewable products of photosynthesis, it is also responsible for photochemical smog, the destruction of the ozone layer and the greenhouse effect. Porter will discuss recent developments in photochemistry and the primary processes of photosynthesis.

Porter received the Nobel Prize in chemistry in 1967. He studied and taught at Cambridge University and held a chair in Sheffield University before becoming the director of the Royal Institution of Great Britain in 1966. He was president of the British Association for the Advancement of Science in 1985-86 and president of the Royal Society of London from 1985-90. He was knighted in 1972, received the Order of Merit in 1989 and was created a life peer in 1990. He is now chairman of the Center for Photomolecular Sciences at Imperial College in London.

Chapman lectures are a yearly UAF event sponsored by the College of Natural Sciences. Dr. Sydney Chapman, considered one of the most distinguished geophysicists of the 20th century, was professor of geophysics and advisory scientific director of UAF's Geophysical Institute from 1951-70.
