Curling up in a ball tends to reduce people's radii, so {{w|Karl Schwarzschild}}'s is given as 0.34 m, corresponding to a black hole of about 40 times the mass of Earth. |

The measurement shown here purports to be the area of {{w|Paul Broca}} (which might refer to the {{w|Body surface area|surface area of his body}}, or the area his body takes up), but it is given in cubic meters (a measure of volume) rather than square meters (a measure of area). (The surface area of an adult human is about two square meters.) This area was recently mentioned in the title text of [[2732: Bursa of Fabricius]]. |
