Problem: Pollution

f T If you'd like to find out about air, water, and noise pollution and be entertained at the same time, the University's College of Engineering has just the thing for you. It's the second annual Faraday Christmas Lecture on Jan. 8 and 9, a three-part lecture featuring plenty of demonstrations. The lecture is geared for people with little science ground. It is named after Michael Paraday, a 19th century scientist who, among other things, invented the electric motor and electrie generator. For a number of years he cond u c t e d demonstration-filled Christmas lectures for school children. The U-M lecture will consist of three half-hour parts conduced by three lecturers. J. Louis York, U-M professor of chemical and metallurgical engineering, will start the series with a discussion of air pollution. He'll Ilústrate his talk with slides and demónstrate air pollution control devices. The question of noise pollution comes next. Richard K. Brown, professor of electrical engineering, will use tape recordings to Ilústrate unusual acoustical effects, then demónstrate ways of suppressing different kinds of noise. The final section deals with water pollution, and will be presented by Walter J. Weber - Jr., professor of civil and water resources engineering at the University. He will demónstrate a device which can turn sewage directly into drinking water. The three-part lecture begins at 8 p.m. Jan. 8 in the Chrysler Center auditorium on the U-M North Campus. It will be repeafed on Jan. 9 at the same time and place. Tickets for the free lecture can be picked up in the U-M Engineering Administration Office, 247 West Engineering Building. Or, you can have them mailed by enclosing a selfaddressed and stamped envelope and sending your request to that office in care of Miss Joan Bild. Limited tickets will also be available atine door. JÊ
