In 1810, he published the results of his scientific research in a massive tome, which he advocated as a new foundation for all of science and mathematics. His theories were strongly Pythagorean, holding numbers and their properties to be the fundamental underpinning of essentially everything in the universe. His claims were met with little acceptance, and his research and theories were generally dismissed as grandiose rubbish. His earlier correspondence with major figures meant that his writings garnered more attention than a typical crackpot theory, even earning a review from the great mathematician Joseph Louis Lagrange (which turned out to be categorically unfavorable). In the ensuing controversy, he was forced to leave the observatory.
