The Science Museum in London is to the Tech Museum in San Jose as a great wine collection is to a selection of California cabernets and chardonnays from a single decade — a much more complete and satisfying way to spend some time.

Here’s a photo of Babbage’s unfinished Difference Engine No. 1, which is in the Science Museum.
