In the last century our understanding of the Universe has gotten an unimaginable boost. Theoretical concepts of both General Relativity and Quantum Mechanics have allowed us to comprehend and, in some cases, even predict physical phenomena taking place on atomic and subatomic scales, and on the scales of the entire Universe, so to speak. This […]Read more "String Theory – part 5: General Relativity vs Quantum Mechanics"
You and Jim are a little bit tired after all those experiments you conducted in order to test Special and General Relativity and are now looking for a bar here on Earth. You have finally found something called ‘H-bar’ which promises you a unique experience unlike anything you have ever encountered before. Of course, you […]Read more "String Theory – part 4: Quantum Mechanics – the World of Weirdness"
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 […]Read more "String Theory – Part 3: General Relativity – The Heart Of Gravity"
How many times have you found yourself in a discussion with someone who doesn’t believe in, for example, evolution, the Moon landings or something else we all just take for granted, something we all just know. You point out what you think is obvious about, say, evolution, only to be met with “Ah yes, but […]Read more "“It’s Just a Theory”"
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 […]Read more "String Theory – part 2: Special Relativity – the Picture of Space and Time"
The Main Conflict of the XX Century Physics The tremendous success of physics during the last century is based on two theories put forward in the first quarter of the XX century. One of them is Einstein’s General Relativity, which describes the Universe on a large scale: from planets to stars, galaxies and galaxy clusters […]Read more "String Theory – part 1: Following Einstein’s Dream"
Next week I am starting a new series of articles concerning String theory. As in the last series, the information for these articles is taken from Brian Greene’s book. This time it is “The Elegant Universe”. We shall be talking about the ideas and purposes of String theory, its concepts and structure, problems, predictions and […]Read more "String Theory – What is It About?"
