A science reporter was interviewing a famous pure mathematician at home. After the interview, his attention was drawn to the various beautiful paintings on the wall depicting well-known mathematical numbers, such as √2, 1729, Fibonacci series, and even transcendentals such as π and e.
Ah yes, they are presents from my artist friends. Aren't they lovely? she asked.
The reporter noticed one painting on the ground depicting 0. Why isn't that one on the wall?
Why, that's the unhung zero, replied the mathematician.
