Talk:Robert Berger (mathematician)
Several problems here:
1. This brief article contradicts the more detailed article at Aperiodic tiling. This article implies that Berger used results from Penrose's work, but the Aperiodic Tiling article gives a completely different history (which is backed up by various articles I found on line). Essentially Dr Hao Wang posed the question if the tiling problem is computable: Berger first proved that the problem is not computable (which implies that there is an aperiodic solution) and then found the first aperiodic solution.
2. This background (which addresses the "too technical" flag) is well covered in Aperiodic tiling. So does it need repeating here?
3. I can't find anything on Robert Berger's life. He's not in the Mathematical Genealogy project - well only if he is the German Robert W Berger and the details don's seem to fit. He is not listed as a Ph D STudent of Dr Wang [http://genealogy.math.ndsu.nodak.edu/html/id.phtml?id=29869
Finally, he seems to have written only the one paper - at least in the area of tiling.
R. Berger, The undecidability of the domino problem, Mem. Amer. Math. Soc. 66, 1966.]
Did he go off to Wall Street rather than pursuing a career in academic mathematics?
Dr/Professor/Mr Berger - if you are reading this please correct me if I am wrong!!
Maybe we should merge? I'm flagging on The Maths articles needing attention to see what happens.
