Computational Gymnastics A technician nearby explained, "This is a routine for the comput- er memory." The computer was merely per- forming a series of involved com- putational gymnastics. A reel of tape was shooting through the photo-electric tape reader. On the tape were trial problems that the computer was running through. Prof. Donald Brown of the Willow Run Research Center, where MIDAC was located, said the purpose of the audio monitor was "to tell if the machine is actually computing." It converts changes in the elec- tronic circuits into audible sounds, By k t imxe, lixeaudior moniz tor had halted its h Iemming and haw - ing sequence.

Only 44 percent believed that an honor .system would be an effective me- thof of curbing the cheating.

The University of Kansas really had its problems. Or at least it seemed that way for a moment. The residents of .a women's dor- mitory there were recently read an ultimatum, The gist of it was that,. due to the. offensive display of affection found shortly prior to closing hours, the administration was prohibiting men from calling at the women's residence halls af- ter b p.m.. The administration felt that the students had misused their privi,- leges and that the ruling would be In. effect until such time as the administration felt that the stud- ents were better able to show their maturity as members of the Uini- verity f aily. The women were still mulling over the new ruling when an April Fool sign was carried In. euun has summed up the career of a. coach in this laconic verse: Desired /'Wired / Hired / In- spired / Admired / TFired / Mired / Fired.
