Ecologist: limnology lives by STEVE STRASSER Nebraska Staff Writer W orld-renowaed ecologist Arthur Hasler doesn't think much of "doomsday scien tists," at least not in his field. "These fellows have been working with flasks in a lab," the University of Wisconsin limnologist told about 180 peo ple at a Bessey Hall lecture Thursday night. 'They haven't gone out and looked at a lake." The lake in his example had been doomed by some scien tists because of a high carbon dioxide content. But, lowering the phosphates content had ac Czech jubilee views Komensky The Czech University Club "Comenius" is preparing a jubilee for this weekend in memory of Jan Komensky.

But lakes cant be saved by one-man crusades, Hasler pointed out. "All kinds of public officials have to be persuaded before any action is taken," he said. "Our political-legal system is not geared to deal with these problems (like lake euthrophication ) . "There should be an Inter-governmental authority to deal with them," Hasler said. Tesina.

Hasler said. "We know the causes, the symptoms, and we have examples which prove that the elimination of man made effluents reverses the process." The man-made effluents In clude detergents, fertilizers, feed lot run-off, exhaust emissions, erosion run-off, and sewage, Hasler explained. Most restored lakes up to now have been saved at the expense of other bodies o water to which the sewage has been transferred, Hasler con tinued. "We have to think of wavs to re-cycle sewage." He added that all ways known now are too expensive. Meanwhile, the battle goes on for Hasler. He related that in fighting to clean up Lake Men dota bordering the Wisconsin campus, he had trouble at tracting attention to the pro blem. "People would go out of their way to throw a can in the lake." So he paid a model $20 to pose waste-deep in the muck and pat the picture on the University president's desk. The lake is being maintained much more carefully now, Hasler reported. And as for the doomsday prophets among his colleagues, "somebody ought to rub their noses in some limnological literature," he said. or sisters and brothers GAY COFFEEHOUSE Sunday, November 22 7:30 pan.

About 20 English courses have been scheduled for living units. The history and philosophy of education and German departments are also offering courses in residen ces. The idea of classes In the living unit allows the topics of the course to continue outside the four walls of the classroom, Hedges said. Dorm classes are technically open to all students, but only those living in the residence hall where the courses are of fered should sign up, the director said. "Since the theory is for discussion to continue outside the classroom, there's no purpose In having classes in residence halls if the students Students study toasters If you're interested in things like toasters, electric fans and grading spectrometers, take the new Physics II lab for non majors. This year's edition of the lab Deli for Guys end Gals fiSray ffto styles fott attend from all over the cam pus," he explained. Courses have been scheduled for all city campus residence halls and "we are hoping to develop classes . in the Burr Fedde complex on East Cam pus," said Hedges. Although the classes win probably meet in the dorms, the option is open for meetings to be held In regular classrooms, he said. Specific meeting places will be an nounced to registered students. Anyone wishing to take courses in living units should have signed up by now, Hedges said. "We tried to get the in formation to people in the liv ing units, and if the grapevine was working properly, the course call numbers should have been available to students." The information can be ob tained from student assistants in the residence halls or the English department, he added. emphasizes "the discovery ap proach rather than the cook book approach," according to Robert Fuller, associate pro fessor of physics. Lab Instructors hand students a scientific enquiry form which "outlines the steps you take when you ask nature questions," said Fuller. Students then use procedures outlined In the form to find out all kinds of "neat things" about appliances like toasters and fans. Fuller explained. Fuller hopes the lab will show students the difference between looking at something and actually observing it Besides observing, the students will also try to make some things on their own, such as a grading spectrometer, aa instrument which measures the light transmitting powers of solutions. Fuller said people working with this course and lab are convinced that labs of this style are the trend of the future. Get ereMen?
