In chapter 61 of How Many Licks, Aaron Santos estimates what causes more tidal forces on a newborn, the moon or the obstetrician?
Astrologists often argue that because heavenly bodies control the ocean’s tides and humans are made of water, the positions of the starts at the time of our birth must control our personalities. These soothsayers neglect the fact that tidal forces are not specific to water, but come about because gravitational forces on an object vary at different location on the object. What causes more tidal force on you at birth: the moon or the obstetrician?
1) The tidal force due to the obstetrician is about 4,000 times greater
2) The tidal force due to the obstetrician is about 40,000 times greater
3) The tidal force due to the obstetrician is about 400,000 times greater
4) The tidal force due to the moon is greater (the #1 answer picked by astrologers!)
