Just noticed this buried in the middle of a Groklaw entry. 100 things we didn’t know this time last year is the year end almanac of BBC’s 10 things we didn’t know last week.

Among the best include:

12. Until the 1940s rhubarb was considered a vegetable. It became a fruit when US customs officials, baffled by the foreign food, decided it should be classified according to the way it was eaten.

19. The = sign was invented by 16th Century Welsh mathematician Robert Recorde, who was fed up with writing “is equal to” in his equations. He chose the two lines because “noe 2 thynges can be moare equalle”.

35. The name Lego came from two Danish words “leg godt”, meaning “play well”. It also means “I put together” in Latin.

48. A quarter of the world’s clematis come from one Guernsey nursery, where production will top 4.5m plants this year alone.

73. One in six children think that broccoli is a baby tree.

74. It takes a gallon of oil to make three fake fur coats.

88. A single “mother” spud from southern Peru gave rise to all the varieties of potato eaten today, scientists have learned.
