Peltier Jean Charles Athanase (1785-1845) Fr. phys., watchmaker, discovered a thermo-electric reduction of temperature which effect is named after him Penrose Roger (1931-) US. math., suggesting that all calculation about both micro- and macro- worlds should use complex numbers, (requires reformulation of major laws of physics) proposed a new model of universe whose building blocks he called twisters (Penrose s tiling). 

The publication of this paper led to a stampede of research, both experimental and theoretical, and an examination of earlier studies by eminent people like Roger Penrose and Alan Mackay in England about the possibilities of filling space by tiling with two distinct populations of tiles, as illustrated in Figure 10.8. This is the basis of quasicrystalline structure. 

In structure, the quasicrystal relates to the Penrose tile structures (polygon), originally proposed by Roger Penrose, a mathematician at Oxford University. See Crystal.

Penrose, Sir Roger (1931- ) British mathematician and physicist. Penrose was the first to point out that singularities are inevitable features of the general theory of relativity. He has made other important contributions to the theory of relativity and its quantization, including his work on twistor theory. He also discovered Penrose patterns, which are a two-dimensional analogue of quasicrystals. See also Hawking, Stephen William.
