You got it right ... today we talk about the Rubik's cube, originally known as the magic cube.
The puzzle was patented by Erno Rubik, a Hungarian designer and architect with a passion for enigma. The first curious fact, however, is that the inventor himself took more than a month to find the solution for its creation. Just think that when the cube was born, Erno didn't even know if there would ever be a solution!
There are several ways, however, to approach the solution of the puzzle. The most intuitive is the layered method: 7 steps to perform and a few algorithms to memorize. The method most used by professional speedcubers, on the other hand, is the Fridrich method, which allows you to solve the cube much faster, grouping second-third, fourth-fifth, sixth-seventh steps of the layered method in single steps.
The Rubik's Cube began to be marketed by Idela Toy Corp in 1980, winning the award for the best game and brain teaser of the year.
And if initially
We don't know the exact moment. The first safe of which we have historical information, however, dates back to Ancient Egypt, precisely to the 13th century BC. And guess what, it was made from wood. Surely arriving at the exact burial place of the Pharaoh was not an easy thing. Pitfalls and traps to overcome without losing body parts or staying dry. For Ramesses II, all this was not enough. He encased his most precious treasures in a wooden safe with a lock similar to that of pin locks. A very ambitious mechanism for three thousand years ago! A further step was taken by the merchants of Ancient Rome, who invented a locking system with fixed flaps to prevent the goods from being stolen. Over time they also began to use flaps of different sizes, so that each safe needed a different key to open. During the Renaissance, a period in which sculpture and architecture flourished like never before, safes became not only more elaborate and safer, but also beautiful to look at. In the
There is a massive text that we will often talk to you about from now on.
It is perhaps the largest written collection ever made in the history of brainteasers and puzzles.
In Puzzles Old and New, in fact, Professor Hoffman, already author of texts on magic tricks and card games, set himself the goal of creating a real illustrated story of all the puzzles to be found, from the past to his present.
After all, we know, starting from the ancient Enigma of the Sphinx, traps and riddles have always fascinated young and old.
Today we want to start from one of the first puzzles present in the pages of the famous text.
It is a thin wooden tray, closed above by a glass plate.
It is called the Planet Puzzle and, in fact, inside it you can see as many small marbles as the planets of the Solar System back then known.
The goal of the puzzle was to get each ball into the hole corresponding to its position with respect to the Sun.
