review 1: Stfd was definitely a good overview but it took a while to realize on kindle that I didn't have to read every single word. The physicial book is split into sidebars and infoboxes so that it's more visually apparent. Ill just call out some of my take aways- 1. The intent behind it all is mostly to come up with a grand theory in which the laws of gravity do not break down on a quantum scale. It's also to come up with a model of the most fundamental unit of existence which we once thought to be the atom but have since narrowed down further. Modern physics does not think of particles as matter anymore- particles are bundles of waves called wave packets.2. The model of the most fundamental unit of existence started off as a vibrating string, then turned into a multidimensional ... morevibrating 'brane' within a 10 or 11 dimension world in which some of the dimensions are curled up inside one another. My understanding is that that's the only way to get all the math to work but there's ongoing dispute as to the exact number of dimensions.3. Supersymmetry, which basically is string theory (basic/bosonic string theory has evolved over time), is kind of like E=mc2 on steroids. It says that every energy force has an associated particle called a gauge particle that 'mediates' it. Light is a convenient example- first we found light waves and then discovered the photon. Now were searching for a massless 'gravitron' that corresponds with gravity. Were also trying to figure out what is up with dark matter and dark energy.
review 2: String Theory for Dummies is the best way for people without an advanced mathematical background to start learning about String Theory. Basically, the main aim of this book is to teach people the fudamentals of the Theory of Everything avoinding as much mathematics as possible.If you are a Physics enthusiast and like to learn advanced things the easy way, just like me, you will love this book. Last year, I made a school project on String Theory and during my research I realized how scarce sources are when it comes to the basics of this theory, maybe it's due to the fact that this field is not very widely researched or maybe because it's recent.That's why this book is so groundbreaking. You'll never regret investing your money on it. less
