"Speakable and unspeakable in Quantum Mechanics" by John S Bell

"Speakable and unspeakable in Quantum Mechanics" by John S Bell is a collection of papers published 1970s - 1980s in concern of foundations of the Quantum Theory. The book addressed many controversies that QM had with the classical world - Non-Locality, Quantum Correlations, EPR-Paradox, Local Hidden Variables and few experiments such as Stern-Gerlach, EPR, GHZ and CHSH.
Bell has been one of the physicists who has grand footing in the Philosophy of Science and I appreciate him a lot for noticing what even the pioneers and founders of the Quantum Physics like Heisenberg, Bohr, Dirac and later Einstein couldn't, to explain certain experiments and controversies. And not just that, Bell clearly proved that quantum correlations are purely non-local with no local-hidden variables embedded in the Nature and do not violate Relativity. Not just that, Bell put it in the simplest mathematics possible for this, probability and pure linear algebra.
This led to the development of Quantum Information Theory and Quantum Computing from 1980s and many quantum algorithms came up one after the other.
And today, IBM has an open source cloud quantum computing hub for everyone to use. Offers more than 12 qubits for anyone to use. Google and Microsoft racing for Quantum Artificial Intelligence.
Physicists like John Bell deserve much more than the non-mainstream community can know or offer.
