I show that, within a quantum mechanical framework, all phenomena which leave a trail of information behind (and hence can be studied by physics) are those where entropy necessarily increases or remains constant. All phenomena where the entropy decreases must not leave…</p><p><a href="https://hackerpaper.kaipfister.de/p/0802.0438/">Paper and discussion history</a>.
