  • The gravity on Earth is 9.8m/s². On the moon it is 1.62 m/s² On mercury it is 3.7 m/s². On Venus it is 8.87 m/s². On Mars it is  3.711 m/s². On Jupiter it is 24.79 m/s². On Saturn it is 10.44 m/s². On Uranus it is 8.69 m/s². On Neptune it is 11.15 m/s².

  • Corvids have the largest brain to body mass ratio of any birds. The brain of an American Crow is on average 2.3% of its body mass, with the common raven at a close 1.3%. For humans the brain is 1.5% of body mass on average, while for domestic chickens the figure is 0.1%.

  • Regular pasteurization causes nutritional loss in milk – calcium and phosphorus drop by 5%, vitamins B1 and B12 drop by 10%, and vitamin C by 20%.

  • Benford’s Law says that when analyzing real life sets of numerical data (populations, areas, numbers appearing in newspapers, etc.) the leading digit is likely to be small. 1 is the leading digit in 30.1% of cases, 2 in 17.6% of cases, 3 in 12.5%, 4(9.7%), 5(7.9%), 6(6.7%), 7(5.8%), 8(5.1%), and 9 only appearing as the leading digit in 4.6% of cases.

  • The determination of the cellular scaling rules that apply to primate brains (Herculano-Houzel et al., 2007) enabled us to predict the cellular composition of the human brain. According to these rules, a generic primate brain of 1.5 kg should have 93 billion neurons, and 112 billion non-neuronal cells: glial cells, thus, should constitute at most half of all brain cells. This generic primate brain should have a cerebral cortex of about 1.4 kg, containing 25 billion neurons, and a cerebellum weighing 120 g, with 70 billion neurons.
