The false dichotomy (or perhaps begging the question) crowd does it again. Is a tomato a fruit or a vegetable? Can a single strawberry be considered alive? If a tree falls in a forest when no one is around, does it make a sound? Now we know that the answer is, "No," since there is no such thing as a tree.
I was hoping that "Frank's Place" was on the list. Loved that show. Looks like I might have to visit the Paley Center. ... and while I am here: How did "As Time Goes By" miss the list?
Strength-to-weight issue are amazingly interesting. Who cares what a cathedral weighs? On the other hand, while balsa wood holds the record, the Spruce Goose shows S/W is not the only consideration.
