For those who didn't understand yesterday's post



Every year I look up information about the number of the age I am becoming to see if I can find anything of interest.

The number 42 is, in The Hitchhiker's Guide to the Galaxy by Douglas Adams, "The Answer to the Ultimate Question of Life, the Universe, and Everything," which is calculated by an enormous supercomputer over a period of 7.5 million years. Unfortunately no one knows what the question is! Thus, to calculate the Ultimate Question, a special computer the size of a small planet using organic components is created and named "Earth."

The picture I posted yesterday is of a "magic cube," constructed in such way that every row, column, corridor, and diagonal passing through the center has numbers whose sum is 42. I don't know who came up with it but I thought it was cool.

Another interesing thing about 42: In 1966, mathematician Paul Cooper theorized that the fastest, most efficient way to travel across continents would be to bore a straight hollow tube directly through the Earth, connecting a set of antipodes, remove the air from the tube and fall through! The first half of the journey consists of free-fall acceleration, while the second half consists of an exactly equal deceleration. The time for such a journey works out to be 42 minutes.

Have a great day, all ;)
