Welcome back!
I trust you had a good week with a break from lectures (n.b., I did not say holiday).
Tomorrow we will discuss the last chapter of Nelson. It is a great one.
Biological question: How can a leaky cable (e.g., a neuron) carry a sharp electrical signal over long distances?
Physical idea: Nonlinearity in the cell membrane's conductance turns the membrane into an excitable mdedium, which can transmit waves by continuously regenerating them.
On more mundane matters on tuesday I want to
-give you a TEVAL to complete
-pin you down on paper presentation topics
-remind you of the assessment details
Also, I will be away for the following 3 weeks, but Seth will attend the tuesday tutorials and talks.
