یادداشت Mika

        I had to study this book in half a day and I got to say that it's really easy to read. The part entitled "experience" in each chapter sets your mind ready for the rest of the material. The material is presented in an organized way which was just so helpful.(I'm not good at memorizing stuff, but this sequence of the material helped me learn much faster than I thought.)
The edition I was reading was the 3rd one, but still it needs updating. Especially the chapter regarding technology.
There are also videos on YouTube to help you with understanding the techniques.
