周光召在全国科技大会上的发言（节选）科学实验已经反复精确地证明，在化学和生物活动的能量层次上，只有电磁场是基本的相互作用力。电子在原子核周围运动，会形成屏蔽、交换，而产生出不同的作用力形式。它们已经可以根据量子力学原理，利用计算机精确地加以模拟和预言... Zhou Guangzhao's Speech at the National Science and Technology Conference (Excerpt) Scientific experiments have repeatedly and precisely demonstrated that only the electromagnetic field is the basic interaction force at the energy level of chemical and biological activities. Electrons move around the nucleus, forming a shield, exchange, and produce different forms of force. They have been able to simulate and predict accurately using computers according to the principles of quantum mechanics ...
