Why is E=mc²?

| March 5, 2012 | 0 Comments

So here we have another book by Brian Cox and Jeff Forshaw. As you might guess from the title, the book deals with one of the most popular equations of all time. Like most of the books by Brian Cox this one is quite easy to read as it isn’t too mathematical. Brian Cox and Jeff Forshaw try to answer the question why E=mc² by digging deep into the history of this famous discovery and the science principles behind it. Naturally, you might think that it’s almost impossible to explain this famous Einstein’s formula with basically no maths, but is surprising how much authors explained with so little.


Basic Info


About the Authors

Brian Cox is a particle physicist, TV personality and a famous popular science author. He is a professor at the University of Manchester and currently works at the ATLAS experiment at the Large Hadron collider at CERN near Geneva, Switzerland.

 Jeff Forshaw is a theoretical physics professor at Manchester University. In addition he also works at CERN with the Large Hadron Collider. His main expertise is particle physics. Professor Jeff’s strength is the ability to explain the beautiful, but often complex, ideas behind the laws of nature to a general audience.


Short Review

My opinion about the book is that the Authors did a good job answering the question from the title. To answer this question they have to dive deep to the laws of physics but they do a great job of explaining the secrets of Einstein’s theories in plain words. I addition, many usual questions regarding the famous equation are also answered in the book.

The great thing about this book is that for about 150 pages the authors give you all the required information you need to know to delve deeper in the science principles behind the mass and energy equivalence. However, in the rest of the book the slope of required technical knowledge rises quite steeply.  Nevertheless, I still think overall the authors still did a good job of explaining many complicated science principles in as simple words as possible.
