Units are unquestionably the most challenging issue for many undergraduate biology students. There are large numbers of students who cannot figure out why grams/liter are different from grams. And don't even think about trying to figure out something like how much water to add to a solution to make a standard concentration. Some can't even immediately grasp that you can't concentrate a solution by adding water to it. On Aug 3, 2012, at 1:37 AM, Bill Gosper wrote:

The 2013 Volt model’s battery-only range has been increased three miles to 38 miles, in part because Chevrolet boosted the storage capacity by .5 kilowatts per hour. The DOE research would seek to improve on existing storage capacity.

Neither McCarthy nor Chaitin. We discussed this ages ago on math-fun, but my personal archive doesn't go back far enough (i.e., prior to 1997).
