discussed in class the general foundations of string theory, based on the videos "The Elegant Universe," which highlights some of the following:
1 - A Theory of the unification of the four forces of nature, finding a single theory that describes all the laws of the universe known to date.
2 - Introduction to string theory as a candidate for a unifying theory, which suggests that all matter and forces are made of tiny strands of energy that vibrate in different modes.
3 - Integration of Heaven and Earth, based on the ideas of Isaac Newton (1665), who joined the laws of Heaven and Earth under the theory of gravity.
4 - details Einstein's discovery that nothing can travel faster than the speed of light, and reveals how this finding is at odds with Newton's laws say that gravity act instantly to any distance.
5 - Einstein with his theory solves General Relativity that gravity also travels at the speed of light.
6 - Unification of Electricity and Magnetism (mid 1800) in a single theory called electromagnetism (Maxwell equations), which is hundreds of billions of times stronger than gravity.
7 - Search of Einstein's unification of electromagnetism and gravity.
8 - Birth of subatomic physics (early 1900) and a look at the development of the theory of quantum mechanics Microcosmos, where uncertainty dominates the quantum world.
9 - Unification of the two additional forces strong and weak calls (discovered 1930), with the electromagnetic force under the umbrella of quantum mechanics.
10 - Challenge unify gravity (general relativity) with the forces of Microcosmos, Strong force, weak force and electromagnetic force (Quantum Mechanics), in order to describe phenomena such as black holes, which are extremely massive and very small.
11 - M-theory, formulated by Edward Witten to unify 5 string theories into one.
12 - It concludes with the idea that while string theory could unify general relativity theory and quantum mechanics, there is by now experimentally to confirm their predictions.
