历史相对论

According to Lorentz transformation,the relativistic covariant of electromagnetic field tensor and 4-dimension forces,and the relativistic invariance of electric charge,it can be directly proved that a moving magnetic monopole will be acted- by a magnetic Lorentz force ,and that the magnetic Lorentz force has the same accuracy as the Coulomb low.

概述了磁单极概念的历史发展，从洛伦兹变换出发，利用电磁场张量和四维力的协变性以及电荷相对论不变，直接证明了运动磁单极受磁洛伦兹力，建议了一个磁洛伦兹力的验证方案，并用磁洛伦兹力公式导出狄拉克电荷量子化条件。证明了磁洛伦兹力公式具有与库仑定律相同的精确度

Relativistic quantum mechanics is the historical origin of the Dirac equation and has become a fixed part of the education of theoretical physicists.

相对论量子力学是Dirac方程及其发展为理论物理教育一个确定分支的历史渊源。

Contrasting with Popper's opposing to the "historicism" in the sense of "historical determinism", Husserl is opposed to the "historism" in the sense of "historical relativism".

与波普所反对的&历史决定论&意义上的&历史主义&不同，胡塞尔反对&历史相对论&意义上的&历史主义&。

Because this book totally negates the issue, argument of special relativity and its mathematical tools, and uses Newton law and light velocity superposition principle to re-explain the important dissent physical experiments in history(including Michelson-Morley experiment).

因为，本书对狭义相对论的论点、论据及其数学工具都进行了全盘否定，并用牛顿定律和光速叠加原理重新解释了历史上重大异议的物理实验(包括 Michelson-Morley 实验)。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
