在政道95华诞之际,作为他当年西南联大的同学、半个世纪的好友及多个项目上的合作伙伴,和大家分享我所了解的李政道.rn政道常说:“物理是我的生活方式.”rn政道的研究领域,除了众所周知的粒子物理与量子场论以外,还广泛涉及天体物理、流体力学、统计物理、凝聚态物理、广义相对论,相对沦重离子碰撞等领域.对于自己的每项研究,他都从最基本的原理和假定出发,从头推导出所有必要的公式.政道非常善于和他人交流探讨,但很少读别人的学术文章.对于别人的工作,他则着重了解其中的未知与未能之处,并常以别人尚不知不能的难题作为自己新的研究方向.所以,一旦进入一个领域,他便能不受已有方法的束缚,常常从全新的角度,很快得到别人没有的结果,彻底改变这个领域的面貌——路是自己重新开拓的,结果又是别人过去没有得到的.
