'Nature' does the same, for 50 and 100 years ago. A recent issue has the prediction from 1973 that beef wouldn't be eaten by the year 2000 because of the production inefficiencies, and a 1923 review of a book about cryptography. I've been reading Nature on and off for about 40 years. When I started, the '100 years' ago pieces were from the late 19th C, and often conjured up an image of amateur gentlemen scientists writing letters to learned societies in London, very different from today. [Edit] 40 years rather than 35. Doesn't time fly!
