![]() However, as it stands, unless you have a strong physics background, don't bother.Researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have utilised string theory to understand the behaviour of particles outside the photon sphere of a black hole.ĭirector Ooguri Hirosi, and project researcher Mathew Donaldson, outlined this research in a new paper published in the journal Physical Review on 24 March 2021. This would have at least given a veneer of understanding. He could at least have spent at least a page on each equation explaining each term and how they evolve with time. These are far too general to give you the vague impression of understanding.īut this book assumes at least graduate level knowledge, and recent at that. I was hoping for a bridge between the popular accounts authored by people like Hawking and Smolin, who avoid any mathematics at all and try to explain via analogies. I know string theory is a very difficult subject, that is why I purchased the book. He has a very dry, lecturer's style, as if he is talking to a graduate student almost his equal and he takes too much for granted. The author's approach was to show you an equation, write a couple of lines about it then move onto another equation even more complicated. However, I was lost after about the third chapter. I understand calculus and differential equations and matrix theory, so the early chapters about classical mechanics, relativity and quantum theory didn't phase me that much. I have a reasonably strong Physics background but I took my physics degree over 30 years ago. I purchased this book on the basis of the title. ![]() Topics Covered Include: What Types of Math? Particles and Relativity Why Did Strings Enter the Picture? So What is String Theory Then? How Many String Theories are There? How are String Theories Related? Is There a More Fundamental Theory? Cosmology How Old is the Universe? Structure of the Universe What is Space-Time Geometry? What Determines Space-Time Geometry? What’s the Geometry of OUR Space-time? Dark Matter? What is the Cosmological Constant? What’s the Final Answer? The Big Bang The Beginning: Plank Era and Inflation Era Quarks Outnumber Anti-quarks Black Holes Abstract Theoretical Black Holes Observable Astrophysical Black Holes Hawking Radiation Poses New Questions Where are the Quantum Microstates String Theory and Black Holes String Theories Answer Black Holes and Branes in String Theory You should already be familiar with atoms, electrons, gravity and the mathematical principles of positive and negative. A basic understanding of scientific and mathematic terms is necessary. We start with the easiest topics such as: What is theoretical physics What types of math do physicists use? By the end of the book, we tackle cosmology, the Big Bang and black holes as they relate to string theory. ![]() You are shown the equations (just so you know they exist and can see how difficult they are), but you are never asked to solve them. However, unlike some books that are filled with equations and difficult math, the book is written in an easy to understand way and guides the reader through string theory. This book provides a detailed look at the development, history, and current state of String Theory.
