“This book will make life easier for a lot of people.”
“Thanks for … making quantum field theory clearer!”
“Extremely helpful and presented in a very readable and understandable way.”
“Awesome. .. approach and presentation .. just awesome!!!”
“Best presentation of QFT I have ever seen …. marvelous!!!”
" transforms learning QFT from being a hazardous endeavor to actually being an enjoyable thing to do."
“Great job .. extremely clear … guided me through the many ambiguities that QFT seems to conceal and that I wasn't able to work out with any other book. .. the Wholeness Charts [are] exceptionally useful ….excellent book..”
“Before, I thought that renormalization was a …. difficult idea, …. but .. now I’ve found [your treatment of it] beautiful, coherent and attractive …”
“Man you are a good writer! Every time I buy and go through yet another textbook, I come right back to your draft…. I start to understand more and more…. Keep it up!”
"I like the way you explain complex matters very much. I think such a book is filling a big hole in educational literature on modern theoretical physics."
"... I cannot restrain my enthusiasm. Your presentation is far superior ... You have my sincere gratitude."
".. first text I see which is at the same time precise, complete and simple on that subject. So it is really a great work."
“Better accessible and organized than any other book I have ever seen.”
“If your book had been available earlier, I would have done a lot better in the class.”
“I'm studying for my first QED exam and I am using your notes when I get stuck … They have been a great help quite a few times … the book .. will help students a lot!”
“I found the level and pedagogy of your explanations refreshingly simple!”
“I really like the way your book explains everything intuitively, yet everything is rigorously proven. Your wholeness charts … are very thought-provoking, and helpful towards seeing the big picture.”
“I am currently taking QFT …and I know I would’ve done considerably better had I found your [web site] sooner than the night before the final!”
“I'm loving every page of this wonderful book.”
“.. presents QFT in a simple, systematic, people friendly manner.”
“A tour de force! You take us on an incredible journey through the “quantum forest”. We get to know its individual trees and admire, from strategic vantage points, large vistas of its connected majestic landscape.”
“.. without a doubt this is one of the best, student friendly books I have ever come across. … amazing creation, …”
“… if it is not already a blockbuster, it will become one when the word about it goes around. Your approach is detailed, pedagogical, and so well organized. You set everything in perspective. Great work..”
“.. you actually take the students’ well-being into account."
“…how enjoyable and great your book is. Thank you for writing it!”
“So often in my classes I feel like the trees are coming at me so fast I can't even keep one eye on the forest. But, your text always seems to keep the big picture in my view. The wholeness charts are a masterful stroke of pedagogic excellence that I find myself constantly referring to as I read and work on the problems. I keep finding new insights each time I return to them.“
“..fine book. I can only hope that schools will do their students a huge favor and begin using it for a first QFT course.”
“ excellent … helped me understand QFT much better than other texts I have looked at.”
“ .. you have thought only of us students while writing the book,..”
“ your book wonderfully demystifies the daunting notation, unspoken assumptions, missing links, and other barriers to understanding … you have my deep gratitude for producing it.”
“Extremely helpful and presented in a very readable and understandable way.”
“I am .. a student at Indian Institute of Science Education and Research … I just cannot thank you enough!”
“.. your one book has made a difference much bigger in my physics education than scores of other standard textbooks and lecture videos.”
"I am a graduate physics student.. your quantum field theory book, is my favorite now.”
“Not only has it helped me greatly in my understanding but having such an accessible and well explained text has massively contributed to my enjoyment of the subject matter as a whole. I can’t fathom why it’s not been picked up by more lecturers.”
“I have thoroughly enjoyed using your book and can honestly say I believe you have achieved what you set out to do it truly is student friendly!”
“.. wonderful textbook. … exactly what the QFT textbooks landscape was missing”
, … if I were ever to have the opportunity of teaching QFT, it is the textbook I would be using. I have recommended it to my advisor”
“Aside from the fact that you give the detailed steps of the derivations, I especially appreciate that you are constantly comparing QFT to NRQM and RQM.... such a clear exposition of QFT and such a thought-provoking essay on the vacuum.”
“extremely valuable! …. all physics books should be written this way.”
“excellent book ….really really student friendly”
“ … a pedagogical masterpiece to say the least.”
“..you are a true educator as you are doing wonders for my understanding of QFT and most of all for answering some of the most difficult questions relating to QFT and QM that confused me for so long.”
“QED cannot be made any simpler”
“… a godsend. …. your explanatory text on the big picture is great.”
“..truly special… extraordinary text. For me, it's an incredible gift… a big relief .. finding your text.”
“Yours (book) is far and away absolutely the best of them all.”
“..truly fantastic... your book is the first book on QFT I know of that really addresses the reader and is extremely agreeable to read in any respect. Many thanks for this book -- I'll have a great summer with it!!
“There is a real need for such texts. Your style is unique and you are an independent thinker. Many of the remarks in your book cannot be found in other texts. And I know of no other textbook which addresses the reader so directly and emphatically.”
“.. a breakthrough in QFT textbooks … significantly more valuable …”
“[a] gem… excellent … a very novel and welcome presentation style.”
“.. fill(s) in many details presumed by other texts. It’s refreshing to have a textbook written for students, not colleagues!”
“.. enjoying your .. book enormously. … nearly perfect presentation.”
“Your approach to a challenging subject is really on target and long overdue in my opinion. Your book really goes the extra mile to help folks..”
“.. you really have made QFT as approachable as possible for the student. Your frequent use of “Wholeness Charts” comparing NRQM, RQM and QFT really helps the reader stay on track with the big-picture while at the same time working through all the unavoidable and essential details. The charts really pay big dividends..”
“… fills in gaps that most books do not”
".. cleared up many misconceptions and is a great read"
“ …outstanding book..
Your remarks on the very meaning of QM and QFT, on their reciprocal relations, on the fact that central issues in QM theory, such as wave function collapse (almost completely ignored in QFT textbooks), are gold nuggets to students. Indeed, they often ask themselves these same questions, but are not able to answer or, even worse, accept the new QFT concepts without a critical analysis, as if they were something different from the old QM ones and, thus, these questions simply did not apply any longer…
… compliments for your precious work”
“… wonderful book for students...QFT can be impenetrable to great minds...your book opens the door.”
“I like your philosophy of "simplicity first". It is time that a QFT book which is correct, .. yet simple and not confusing to follow, was published. I very much enjoyed reading it. I found it written clearly in a refreshing style”
