iClicker data update

The iClicker data are now caught up to yesterday's lecture, L26. Total iCLicker 2 questions to date is 58, but we have two more regular lectures ahead of us:

1. L27 on Tuesday, Nov. 20, regular lecture on chemical compounds and bonding, after which we break for Thanksgiving Day, then
2. L28 on Tuesday, Nov. 27, concerning the structure of water, retinal and DNA.

Each will have some clicking to do.
