String Theory – part 6: The Basic Principles

The Standard Model of particle physics describes all elementary particles as point-like objects. Hence, they neither extend in any direction nor possess any internal structure. Despite its tremendous success in predicting any physical phenomena in particle physics, we can be sure that it is incomplete since it describes only three interactions, leaving gravitational interaction behind. […]

String Theory – Part 3: General Relativity – The Heart Of Gravity

In his Special theory of Relativity, which we were considering in the previous chapter, Einstein resolved the physical conflict which regarded the speed of light and our intuitive understanding of motion. He showed that our perceptions of motion need be changed when we are talking about objects that are moving extremely fast. However, soon after […]

String Theory – part 2: Special Relativity – the Picture of Space and Time

Solving the First Conflict 110 years ago, in June 1905, Albert Einstein, a young person from a Swiss bureau, sent a paper titled “Zur Elektrodynamik bewegter Körper” to the German journal Annalen der Physik in which he provided a solution to the speed of light paradox that had puzzled him 10 years earlier. This was […]
