Lo Que Cabe En El Espacio (LQCEEE)
My LQCEE is a book (written in Spanish) that covers questions about the nature of our geometrical reality, such as why we live in a space with 3 dimensions and whether the space is a simple generalisation of the plane (is not!). How many forms and shapes can be built in a plane, space or higher dimensional hyperspace? Literally, LQCEEE means "What it fits in the space" and we cover from ancient stones found in Scotland through Kant, Saccheri, Kepler and reading Euclid's Elements's most important theorems early determining fundamental geometrical properties of our habitable universe, to more modern exciting developments through Hilbert and others that tell us how special (or not) is the mathematical space in which we live.
The book was published by the Physics Institute of the National University of Mexico (UNAM) and is available free online in PDF and now is available for Kindle on Amazon at these links or for free in mobi format and PDF here:
