I like the fourth interpretation of matrix multiplication from geometric algebra, which brilliantly encapsulates geometric transformations. This approach shifts our focus from just numbers to the geometry of space, revealing how matrices can elegantly describe rotations, reflections, and scaling. It’s a vivid and intuitive perspective that brings matrix operations to life, especially in fields where visualizing these transformations is key, like in computer graphics or physics. It’s like watching math and geometry dance together!
It is interesting that you should say that, because last year I tried to open an online (only) bank account. I live in the Netherlands and finally chose for N26, but I was surprised by the large amount of online banks in the UK. Like Monese, Monzo, Revolut, Starling, ANNA, Tide, etc etc
