General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. Wha...
It wasn't until ten years later that R. A. Millikan confirmed Einstein's photoelectric equation. Millikan nevertheless denied that it proved Einstein's radical but clairvoyant ideas about light quanta! If the energy travels as a spherical light wave radiated into space in all directions, how ...

The Lorentz symmetry is violated in UV since time and space are treated differently. On the other hand, this symmetry can be violated locally through a spontaneous symmetry breaking [2]. However, the Hořava theory presents problems such as instabilities that arise precisely due to the presence...
Using these two premises, Einstein illustrates that time and space are interwoven in ways that humans have never understood before. By way of thought experiments, he showed that the implications of special Relativity baffle conventional human logic: ...
winner, who solved the riddle of the photoelectric effect and proposed the general theory of relativity, died on April 18, 1955, aged 76 after laying the foundation of modern physics and changing mankind's views on space, time, mass, and energy. But did you know he was obsessed...
今天是周日,无约,在家复习Einstein Field Equation (EFE) 的推导方法, 尤其是由希尔伯特作用量的内变分导出EFE; 顺便复习下张量的微积分,为即将到来的machine learning的流刑研究做准备,更重要的是加速我的打字速度,因为最近因为打字慢,被深深的鄙视了...Before we get started, I have to assume that for every...
Einstein would recall that his years in Zürich were some of the happiest years of his life. He met many students who would become loyal friends, such as Marcel Grossmann, a mathematician, and Besso, with whom he enjoyed lengthy conversations aboutspaceand time. He also met his future wife,...
