Mathematicians struggled to find the fewest number of pieces needed to cut an equilateral triangle and rearrange it into a perfect square. The problem, known as “Dudeney’s dissection” or the ...

A geometry problem over a century old has just found its definitive answer. Mathematicians have confirmed that the solution ...

Now, more than 122 years after it was first proposed, Kamata and two other mathematicians have finally proved that a solution ...

the English author and mathematician Henry Ernest Dudeney posed a puzzle: Can any equilateral triangle be cut into as few pieces as possible that will fit together to form a perfect square?

Once you’ve got the puzzle cut out, you can seal up the surface nicely, toss it in a box, and then you’ve got a personalized present. To put it together, we suggest an accompanying DIY pick ...

The square cut allows batsmen to free their arms and hit the ball with a cross bat, enabling them to get plenty of power on the shot. But be careful, although a square cut can bag you plenty of runs, ...
