At 91¿ì»îÁÖ Aquinas College, sophomores embark on a journey of astronomical mathematics. They begin with Ptolemy of Ancient Greece, then explore the works of his successors. œ˜We study these things as a chronicle of humanity™s striving to apprehend the universe around it,� says Tutor Dr. Christopher Oleson. œNot only is it important, it™s wonderful.�

The father of two TAC seniors, Tom VanDamme recently came to the California campus to present his company™s , an armillary designed to visualize Ptolemy™s model of the universe and its motion. Made up of discs, rings, and magnets, the globe helps astronomy newcomers make sense of the at-times confounding movement of stars and planets.

Mr. VanDamme demonstrated the device™s motion with jokes and mnemonics, while also reflecting on the importance of astronomy. œHistorically, [astronomy] is one of humanity™s first sciences. They started from meticulous observation of a wide host of these things, the stars, and put it all together into theories and proofs. And it all started by paying attention to the cosmos,� he continued. œIt™s something anyone can do at home, right in their backyard!�

When asked about his favorite aspect of astronomy, Mr. VanDamme replied, œI love the wonder and awe it inspires. Not only that, but anywhere I am, I can figure out where most stars and planets are in the sky. I just need to know where the sun is and the time of day and ” just like that ” I™ve got it,� he grinned. œIt™s a wonderful trick to show friends and family.�
