&gt; OK, so one can derive Special Relativity from simple models based on networks. What about General Relativity—which, after all, is what we’re celebrating today? Here the news is very good too: subject to various assumptions, I managed in the late 1990s to derive Einstein’s Equations from the dynamics of networks.<p>What a crackpot. He links to his own book, which is a non-mathematical, non-technical book.<p>There is no mathematics in the linked material, so it&#x27;s impossible to see whether he is correct, in fact it&#x27;s impossible to see what he means at all!<p>Nobody has seen this mythical derivation he did in the 90s.<p>Amazing how someone brilliant who used to do real science fell into crackpottery like this.
