The HS, Homo Sapiens, series of computers is the most difficult of all computers to work with. This is because it is a parallel, dual mode, computer. Sometimes, if you program one of the modes, the other mode will override the first mode resulting in nothing being done at all. In this presentation I will show you why it is difficult to program an HS series computer. You will learn what science knows about our brain, how we learn, how sleeping helps, and how biases affect us. You will also learn techniques to help improve your learning.
