Narration In Pursuance Of Books Why Does E=mc²? (And Why Should We Care?)

The most accessible, entertaining, and enlightening explanation of the best-known physics equation in the world, as rendered by two of today’s leading scientists.

Professor Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein’s most famous equation, E=mc2. Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.

Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

Judge Regarding Books Why Does E=mc²? (And Why Should We Care?)

2020 TBR Challenge: Read a book you don't remember why you added or boughtI really enjoy Brian Cox, I watched his series Wonders of Life ages ago, and I've always liked seeing him on various panel shows etc. He is incredibly intelligent (to state the obvious), but gets across ideas in an accessible and easily understood way, and has a great sense of humour to boot.This all extends to Why Does E=mc²? - I still don't think I fully grasp any of the concepts explored in it, I have never had a brain

Easily the most straight forward explanation of this big question that I have come across, including many of the oversimplified youtube explanations that don't quite do it justice.

Einsteins theory of special relativity for dummies. Which, in this case, is probably most of us.It will be hard for someone to come up with a simpler way to explain Einsteins work - if youre well versed on maths or physics, you will probably find this annoying or maybe too dumbed down. But this isnt for you - its for all people that are curious about Einstein and our universe, can follow a logical discussion, but are not technical enough to follow a more detailed explanation. Not that this isnt

Great read however I would say you need to have a basic understanding of physics before reading

Actual Rating: 3.5 Stars.The writing of science books is a difficult task. On one hand, you have a ready market of science nerds that will instantly pick up your book (an easy sale), but they want hard facts, maths and challenging concepts. On the other hand you have a large mass market audience wanting desperately to learn more about science but if you dive in with the hard facts, maths and challenging concepts you are (possibly) going to lose some of them along the way and turn them off

So, first of all, this is a lovely little introduction to relativity, both special and general, produced with just the right amount of math to make all the concepts clear without too many confounding and always unhelpful analogies (though at times it did feel a bit patronizing they spend quite a while explaining, for example, the concept of a variable that, if you dont already have in your toolbox, pretty likely means you will not be able to follow any of the math anyway).Now, how this was
