杨振宁先生是与牛顿，麦克斯韦，爱因斯坦比肩的大物理学家. 下面是1994年杨振宁先生获Bower奖的颁奖词：
"For the formulation of a general field theory which synthesizes the physical laws of nature and provides us with an understanding of the fundamental forces of the universe. As one of the conceptual masterpieces of the twentieth century explaining the interaction of subatomic particles, his theory has profoundly reshaped the development of physics and modern geometry during the last forty years. This theoretical model, already ranked alongside the works of Newton, Maxwell, and Einstein, will surely have a comparable influence on future generations. These scientific contributions combined with his championing of understanding between China and the Western world and his promotion of science education among the youth in all corners of the globe reflect the scientific and humanitarian genius of Franklin himself."

牛顿，麦克斯韦，爱因斯坦对不同的场有贡献。
杨对场论也进行了研究做了贡献。
但是，不能就可以说，杨就与上述三人比肩了。这是个逻辑上的狡辩。
