Mathematics, applications of mathematics to life in general, and my life as a mathematician.
Alexander Karabegov sends me new puzzles from time to time. This time, however, it is not a puzzle but a math joke.
Joke. If a woman gives birth to a child at the age of 30, then 60 years earlier, her child was twice as old as she was. Whatever that means.
What about this one: The son is 21 years younger than the mother. In 6 years he will be 5 times younger than her. What does the father do?
A: he will be annoyed at the nonsensical and incorrict phrase ” 5 times younger”.
The father retires
