31. Near the end of his life, Wigner 's thoughts turned more philosophical. 32. Their fundamental importance in quantum physics is further demonstrated by Wigner 's Theorem. 33. This can be verified by applying the convolution property of the Wigner distribution function. 34. Thus the kernel corresponding to the smoothed pseudo Wigner distribution has a separable form. 35. The definition of Wigner distribution is as follows: 36. In 1976 the Nishina Memorial Prize in Japan and in 2006 the Wigner Medal. 37. Then, he became a member of the theoretical group led by Eugene Wigner . 38. Wigner was afraid that the German nuclear weapon project would develop an atomic bomb first.39. He also met fellow Hungarian students Eugene Wigner , John von Neumann and Dennis Gabor. 40. Eugene Wigner later described the thesis as " a masterpiece of clarity and concreteness ".
