\"Physics<\/figure>\n

A few weeks ago we posted<\/a> the puzzle on the right – well, here’s the answer.<\/h2>\n<\/div>\n
<\/div>\n
\n

A simple pendulum has a period given by<\/h3>\n
\"T<\/figure>\n

If you insert that into the expression in the puzzle you get<\/h3>\n
\"(pi<\/figure>\n

That simplifies to\u00a0\u03c0g<\/em><\/strong> – which you could\u00a0otherwise write as pi g<\/em><\/strong>!<\/h3>\n

Not too complicated, providing you\u00a0spot the trick! If you think of or find similar puzzles, why not\u00a0let us know through\u00a0Twitter<\/a>, Facebook<\/a>, email<\/a> or our contact form<\/a>.<\/p>\n
