for those enchanted by the elegance of mathematics, i have a unique proposal that might just pique your interest: "the disowned calculus: a journey into pre-institutional mathematics." this book invites readers to recommence from the start, delving into theories and equations that have been, until now, kept intriguingly under wraps. it uncovers the hidden roots of today's mathematical principles and breathes life into the ancient, pre-institutional times when mathematics was as much an art as it was a science.
