Here in Math, after doing logic and proof theory first, we have done divisibility, primes, gcd and Euclidean algorithm already. As a first this year, I included to discuss these notions also a bit for Gaussian integers Z[i] right to start with. Thursday we began to discuss congruences and Monday, we’ll get real yummy modular arithmetic. Hey we need that for the cool crypto stuff.

]]>The biology class took a mini field trip to the museum in order to see the Geology and Fossil History of Tennessee gallery, as well as a selection of trace fossils pulled from the museum’s collections. Unlike most of the fossils discussed in class thus far, trace fossils represent preserved evidence of ancient behaviors. Several footprints and trackways were on hand, as were fragments of dinosaur eggshells and coprolites (fossilized dung).

As a bonus, the Knoxville Zoo recently celebrated the birth of two Western Lowland Gorilla babies, a subspecies of primate that is classified as critically endangered. The zoo staff allowed a few people at a time to visit the newborns and their parents. Check out this photograph of one of the babies and another of students at the South American bird exhibit here: ]]>
