Irrationality of π² implies the infinitude of primes

Posted on 2020/04/04 by Carl Robitaille

Since π²/6=∏(1-1/p²)⁻¹ , the irrationality of π² implies the infinitude of primes. A finite product of rationals will always be rational.

On arXiv today, one of the strangest math papers I’ve seen: a proof of a result in metric geometry in the form of a fantasy novellette

On arXiv today, one of the strangest math papers I've seen: a proof of a result in metric geometry in the form of a fantasy novellette.

According to the acknowledgments, the paper is a retort by the author against those who complain that his research articles are too verbose. https://t.co/FeXhPMW8a8
