This is a paper by Leslie Lamport, a computer scientist who created LaTex and TLA+ (Temporal Logic of Actions), among other innovations in the areas of distributed computing, concurrent and reactive systems.

He retired from Microsoft earlier this year. A draft of his newest book is available on the same site as this post.

i really appreciated the paper and as someone who has spent many years deciphering what the author calls 17th century-style proofs am completely aligned with the objective and the method. i personally find myself doing a version of what the author proposes (in private notes) to make sure i understand proofs i read in books or papers.

even so it would have been timely, useful, and relevant to include a comparison to proofs in lean by comparison to TLA+ even though it is not Lamport’s personal project.
