Life and Chess: Who’s playing?

All chess games have three stages: the opening, the mid-game and the endgame. And a chess game is a reasonably good metaphor for life.

When Your Child is as Big as You

My mom used to say that when your child is as big as you, you have to treat them with respect. What she actually said was that you had to address them using a respectful form ofyou,” which doesn’t make any sense in English, but may work in Hindi or French.

At first glance, it says that if you are standing somewhere, and there is a ray of light going from your right to left, it has a speed c. And another ray of light going from left to right also has a speed c. So far, so good. Now let’s say you are in a rocket ship, as shown in the figure below, moving from right to left.
