We will discuss amazing aspects of animals and some of their symbiotic relationships with insects, plants, and other animals. For example, a few of these amazing creatures include the talking Wood Duck, the Crimson Worm and her awesome story she has to tell, plus you will be amazed at the Lampsilis Mussel and what she does all without eyes and a brain.

Black holes might be the weirdest objects in the universe. The possibility that they might exist was suggested by Schwartzschild in 1916 using Einstein's theory of general relativity. Einstein commended Schwartzschild's mathematics, but he didn't believe that nature would allow such an odd object to exist. We now know that black holes are common in the universe and recent experiments have allowed them to be directly observed. This lecture will discuss their properties and how they continue to perplex physicists.
