The mathematical values of Linear A fraction signs

A recent study by a team based at the University of Bologna, published in the Journal of Archeological Science, has shed new light on the Minoan system of fractions, one of the outstanding enigmas tied to the ancient writing ...

The mathematical magic of bending grids

An amazing construction method for curved structures was developed at TU Wien (Vienna): With a flick of the wrist, flat grids become a 3-D shape.

Supercapacitors turbocharged by laxatives

An international team of scientists, including a professor of chemistry from the University of Bristol, has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents ...
