I suggested this brilliant idea to Mike Bara today, and if it was a success I wouldn't even invoice him for the marketing consultancy.
Since my suggestion is very likely to disappear from his blog quite soon, and it seems a shame to waste the ten minutes it took me to come up with 12 errors, I reproduce it here:
JANUARY (p.34) Mars and Earth would remain at the same distance from each other if Mars’ orbit were circular.
FEBRUARY (p.47) Mauna Kea is at 19.5°N.
MARCH (p.15) Scientists don’t realize that Newton & Einstein aren’t the whole picture.
APRIL (p.31) Astrology is a perfectly valid and defensible science.
MAY (p.32) The centrifugal force of Earth’s rotation tends to make us heavier.
JUNE (p.60) Newton’s laws of motion only work if the object being measured doesn’t rotate.
JULY (p.128) The International Space Station is really called Isis.
AUGUST (p.134) Gravity is only a local effect.
SEPTEMBER (p.139) Faraday cages are made of lead.
OCTOBER (p.202) The Brookings Report “detailed how best to inform the public in the event that NASA discovered extraterrestrial artifacts on the Moon or Mars.”
NOVEMBER (p.143) (appropriately) Sputnik was launched in November 1957.
DECEMBER (P.214) An annular eclipse occurs when the Moon is closer than usual to the Earth.
