David Smith (amateur mathematician)

David Smith is an amateur mathematician and retired print technician from Bridlington, England,[1] who is best known for his discoveries related to aperiodic monotiles that helped to solve the einstein problem.

[2][3] Smith discovered a 13-sided polygon in November 2022 whilst using a software package called PolyForm Puzzle Solver to experiment with different shapes.

[1] By mid-January 2023, Kaplan enlisted software developer Joseph Samuel Myers from Cambridge and mathematician Chaim Goodman-Strauss from the University of Arkansas in order to help complete the proof.

[5] Myers realised that "the hat" and "the turtle" were in fact a part of the same continuum of shapes, which possessed the same aperiodic tiling properties but with sides of varying lengths.

[8] The team worked on a proof that confirmed the chiral aperiodic tiling property of "the spectre" and published a preprint paper in May 2023.
