The speed of light, the fine structure constant, and Newton's constant of gravity -- these are just three among the many physical constants that define our picture of the world. Where do they come from? Are they constant in time and across space? In this book, physicist and author Harald...
fundamental constants That group of physical constants which play a fundamental role in the basic theories of physics. These constants include the speed of light in vacuum,c; the magnitude of the charge on the electron,e, which is the fundamental unit of electric charge; the mass of the elect...

The broad field of precision metrology and the measurement of the fundamental constants of physics has been discussed in the previous sections; here an attempt will be made to bring these and related measurements together and to evaluate the significance of the measurements, as a whole, with ...
If a teacher enforces the education of fundamental physics viewpoint,fundamental physics method and studying method to student based on the characteristics of physics,the teaching may be better. 物理学科难教难学是一个普遍问题 ,如果在教学中根据物理学科特点 ,对学生进行基本物理观点和基本物理方法的培...
