A puzzle according to the official definition of the word is a mental problem that requires thinking to solve it.

  • There are various kinds of puzzles, such as logic puzzles, calculus, quizzes, etc. Many times we have to think in an unconventional way to get to their solution. One of the oldest puzzle lovers was the Greek mathematician Archimedes who invented several mathematical problems for his contemporaries to solve.
  • Many people deal with puzzles. Some build them and many are trying to solve them. Mathematician Alfred Posamentier in his book “math nuggets” tells:
    “In 1986, British Christopher Monckton, chief advisor of England’s former Iron Lady Margaret Thatcher, gave her a small 12-pieces puzzle when he resinged. Three years later, Thatcher sent him a letter and asked for the solution, which was the inspiration for Monckton to invent a bigger and tougher puzzle. “

There are several famous puzzles that no one has ever solved. Here is one of them:

Tatjiana van Vark’s haiku

Tatjana Joëlle van Vark is a Dutch scientist with a strong artistic nature. She developed cryptographic machines that take us to other eras and are works of art and technology. At some point, she made an encryption device, the principles of which are based on the awesome Enigma of the Second World War.

She even promised to share the details of how it works if her encrypted haiku is decoded:

It is short and the decryptographers considered it to be an easy job but nobody has done it yet. Can you?
