Professor Diamond continues her discussion of the nervous system beginning with processes - extensions of the soma. She describes axons, dendrites and the types of synapses: axodendritic, axoaxomic, axosomatic, and dendrodentritic. She then describes how neurotransmitters travel from the presynaptic terminal of an axon to the postsynaptic terminal of a dendrite in an axodendritic synapse. Professor Diamond continues with neuron classifi...more

After a discussion of electrochemical cells, Professor Sylvia Ceyer defines the points of oxidation and reduction in a battery as the anode and cathode, respectively. She discusses the application of Faraday's Law and its relationship to electrochemical cells. Finally, the relationship between cell potential and Gibbs free energy is highlighted.

Martin Eberhard discusses the shortfalls of using Solar Energy as a key component in manufacturing a car. He believes that using fuel-cells to drive cars is a huge stretch in imagination. He finally notes that a mix of plug-in hybrid and gasoline is a viable idea for an interim solution for alternative energy sources to drive a car.
