Hypercubes: a jump through dimensions

Here you can find an article (in Italian) I wrote in 2020, to present some topics of topology, combination math and higher-dimensional geometry to high school students. The reason was the 2020 edition of the project MATh.en.JEANS, which I attended during the last three years of high school (2016-2018).

Infinite grid of resistors

Check out this nice problem (and also the relevant xkcd). It has no practical use in electronics, hence I put it under the maths page. I'd really like to understand the problem better and write some original explanation, eventually.
