QED - The Strange Theory of Light and Matter (Penguin Press Science)

and a very interesting read if you want an insight into modern physics by an all-time genius in the field

A very thought-provoking book about quantum mechanics and in particular the theory of quantum electrodynamics (QED) as it was understood in the 1960-80s. Since then some ideas have moved on such as how elementary particles get their mass - now explained by the Higgs field. But this should not distract from the central theme of the book how to explain in simple terms the weird and wonderful world of quantum physics. Good job that Feynman had a brilliant sense of humour since nature is so absurd we can never fully understand it - light does not always travel in straight lines, or is even limited to the speed of light.

I first encountered this series of books, written by Richard P Feynman, in my local book retailer and I was surprised at their size. Despite the nature of their subject, they are barely a couple hundred pages in length. Usually scientific books are much thicker volumes. But when one realises these books were written from notes derived for student presentations by Feynman, then size doesn't really matter. I am more inclined to purchase a 'thin' book than a 'thick' book because apart from being cheaper to buy and easier to carry, it should be an easier book to read. Doubtless, size is a marketing ploy but it means these books are affordable to a great many more people.The information these books contain, often illustrated by original drawings by the author, help to convey some quite complex theories. These theories maybe right or they maybe wrong but they serve to illustrate the thoughts of a 'genius' whom many professionals believe rivalled Einstein in terms of his vision of how the universe works. Feynman was a controversial, colourful, some say eccentric theoretical physicist who cared little for convention and left an indelible mark in understanding science.I purchased 3 books in this series and I purchased 3 more for a friend's birthday. Doubtless I will purchase other books in the same series when I have time to read them.

I've read quite a few physics book, in particular a few introducing quantum mechanics. Whilst the subject never fails to enthrall me, I've found that authors' explanations can sometimes be long winded and dreary (e.g. Brian Cox - The Quantum Universe), however this book manages to maintain interest for the whole length. Whether it be the relatively short size or Feynman's witty and conscientiously explanatory writing style, this book manages to do two things: educate the reader quite a lot about particle physics and quantum theory, and also be highly entertaining, even amusing at times - this is something I have never observed in a physics book before.This collection of lectures defies its age, and if you are an amateur who wants to learn and also to be mildly entertained, them you need look no further.

I believe this is a very manageable book for many levels of scientific background, personally I have just finished my A-levels and found it at a comfortable level. All the key points in the lectures are explained with Feynman's characteristic clarity! It is a really easy book to get into as it feels as if you are having a conversation with an old friend. I recommend reading each lecture in single sittings, rather than breaking them up. This helps keep the ideas fresh in your head - though Feynman does do an excellent job of revisiting major points, so no worries if you don't remember everything!

His style of writing and logical thought makes it all that much easier to understand the theory and he brings into account natural real-life examples, surprising you or making you think about something you never really took into consideration. The book focuses on QED as you might expect but you may not realise how hard it is to find a book in this day that gives you lectures on one particular topic. I would rather read five books on five topics than read five books with less depth and overlaps between content, but that is merely my opinion. I enjoyed knowing this in depth rather than having it described to me.

Book and price are great but it was delivered to my next door neighbours house while I was sat watching on my CCTV. No attempt made to deliver to my address straight to next door?? Delivery is usually spot on so just put it down to experience. Thank you.

Christmas present - requested so sure it will be enjoyed
