Volker Steuber Biocomputation Research Group University of Hertfordshire UK vsteuberhertsacuk HodgkinHuxley Model 60 years and one Nobel Prize later The HodgkinHuxley model is phenomenological rather than mechanistic. Early ocean studies. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. Currents. Ocean water contains streamlike movements of water called . ocean currents.. Currents can travel extremely far. In ancient times, currents were largely responsible for any human travel across the oceans. It is believed that currents carried the ancient Peruvians over 6,000 km across the south pacific to Polynesia. . Na. +. Al. 3+. S. 2–. 2Ca. 2+. PO. 4. 3–. 3Cl. –. Review: forming ions. Ionic (i.e. salt) refers to +ve ion plus -ve ion. Usually this is a metal + non-metal or metal + polyatomic ion (e.g. NaCl, NaClO. What is a current?. 1.
