Does the universe work like a TARDIS?
<p>I’m not sure where it came from originally. This one was posted by the prolific Cliff Pickover without credit.</p>
<p>The interesting thing about this problem is that, as the description says, it can be solved with only a pre-schooler’s knowledge. The apparent complexity hides a deeper simplicity that tricks a more educated person into trying all kinds of arthimetic and cyphers to solve it.</p>
<p>After solving it myself in about 5–10 minutes, showing just how childlike I am, I gave this problem to each of my three children: aged 19, 16, and 8.</p>
<p>The 19 year old gave up after seven minutes. The 16 year old persisted for about half an hour before giving up. The 8 year old took a look and, scratching her head, didn’t venture to try to solve it.</p>
