Jennifer Abbe Alisa Abille Melinda Ablard Franklin Acevedo Digital Computers Rely On Logical Statements Mathematics played a significant role in every aspect of our lives, in balancing a checkbook, or in keeping accounts, for instance. On the professional level, it was used in medicine, engineering, chemistry, physics, and more so in the future with our advancing technology. For example, operations with the logical statements used in mathematics were also applied to the design of electronic digital computers. According to Ed Boughton, Department Chairman, one had to know the logical steps in any solution before one could properly program it into computer language. More than two thirds of the student body were en- rolled in math courses. For the college bound student a total of three years of mathematics were required. Among the various math courses offered were Algebra I, Algebra II, Geometry, and Math Analysis. BELOW: LISA ABILLE gets help from her neighbor. BELOW LEFT: Allen Sayward are you daydreaming again?

Science Is Bridges, Autos, Cells, Formulas In October seniors openly hauled loads of balsa wood, string, and glue across campus.-No smug- gling for them! These exotic materials eventually turned into bridges, the first semester project for Physics 4 Ab. Building bridges taught students the answer to the burning question: Who’s bridge could hold the most weight? Stephanie Clark’s bridge accomodated greatest mass at 15,000 grams. The same Physicists designed and built air pro- pelled cars to discover the principles of friction and acceleration. A side benefit was the speed achieved by each car. As far as students were concerned Ken Brown taught all future chemists to figure formulas, 2Mg+ 02-§2Mg0, AX-§A+ X, because college entry required such knowledge. Lab experiments dealt with composition of formulas, decomposi- tion of different masses, and volumes and densi- ties. The biological highlight was frog dissection. Supposedly those who dissected learned lots about muscles and internal organs, as science marched forward! | ae Y; eR: ‘ - ’ x Donna Bluehle Bradley Breuner Brewton Barbara Bright
