The energy of light carries much of the world's information from one place to another. Surgeons, dentists, dermatologists, and other medical professionals use light in its various forms to heal or repair the body. Business and industry rely on optical scanners and electric eye detectors to monitor production quality, maintain security, and keep track of sales and inventory. Simple electric signs advertise products and services and high-tech bundles of hair-thin glass fibers send voices and data around the world. All this and more is done with the power of light. Optics is one of the fundamental disciplines that has driven the technological and communications revolutions of the 20th century, and it literally defines what the world looks like today. an overview of the theory of light as it stands today, in language that students will find both interesting and easy-to-follow. Covering the history of optics as a science and as a technology, as well as showing the ways in which light has been put to work as a tool, this book discusses three of the great triumphs of optical physics in the 20th century in detail - the creation of laser light; the development of fiber optics and optical-based communication; and the progression towards optical computing, which is seen by many computer experts as the next great phase in information technology.

Optics
Leonard Susskind is definitely the best alive physicist. I've recently learned about him that he was the man who treated Veneziano's dual model as quantum mechanical oscillating string.
This book is very hard to comprehend. All the topics are so abstract that you can merely imagine what is going on. Starting with simple Schwarzchild metric and doing manipulations in a way that you get conformally flat Minkowski space-time and then transform it to Rindler space is like whatever. Penrose diagrams are fatality.
On the other hands, authors get through different topics cohesively. I have no degree in physics, but I was able to follow majority of logic flow. The main aim of this book is explore black holes and show that they can be represented as a very very big 1 dimensional string
Black holes are extremely rare objects to observe in reality. However, they are just solutions to Einstein equations and physicist love to do so (solve those non-linear differential equations in arbitrary space-times in D dimension - whatever 2). If there exists a black hole then you can do some theoretical experiments. You can either stand far away from horizon or fall into a black hole.
That is the main observation in the book that discussions go around. Some fundamental laws should have to be modified that our current understanding of black holes be more realistic (and reasonable).
This book discusses 4 different views: Black Hole Complimentary, UV/IR connection, Holographic principle and String view of Black Holes. There are some mathematical formulas around to prove assumptions. At the end, you see that there exists a pattern: You have to find a connection between Bekenstein-Hawking entropy formula and statistical microscopic states or thermodynamic entropy.
Authors claim that calculations on all types of black holes that were studied precisely agree with Bekenstein-Hawking entropy formula.
