From time to time I come across statements that a domain expert has
anywhere from 30,000 to 100,000 chunks of knowledge (the figure varies
according to the article). How can anybody possibly come up with a
meaningful figure in this area? How were these numbers calculated?
How much knowledge is in a chunk? Does a chunk of domain expertise have
very much meaning apart from chunks of common sense and world knowledge?

I believe that it is the same number as the number of angels that can balance on the head of a pin. Now if modern science can answer this simple medievil problem...

FYI: As I heard it, this was a serious question, and had to do with something approximately like whether angels had finite size or not. Now if modern science can answer this simple medievil problem... I think that Doug Lenat has tried, for the original problem. At least (I think he says) you can estimate how much information a human learns by multiplying the amount that he tends to learn per unit time over the time he lives. You need to make some assumptions, but the idea is to get a ballpark estimate of at least an upper limit. I am not saying that this is the bes way to go about it, but it is at least one approach. (I think that there is a lot riding on what a fact really is.) -- If you do not receive a reply from me, please resend your mail; occasionally this site's mail gets delayed.
