Show HN: Formalizing Principia Mathematica using Lean
Rewriting Prof. Bertrand Russell's Principia Mathematica in Lean - ndrwnaguib/principia
This project aims to formalize the first volume of Prof. Bertrand Russell’s Principia Mathematica using the Lean theorem prover. It was only a result of my greed to write a tactic that handles a more general form of syllogism; I believe in the case of the Principia, I could have got away with one that accepts two hypotheses. Although the Principia is thought to be “a monumental failure”, as said by Prof. Freeman Dyson, it was an enriching experience for me to read as well as to formalize-especially after observing how the latter, more complicated results, are obtained using simpler ones I personally formalized.
