I want to read this book(in English) but I was told that this book is very hard to read. I was wondering if there's an edition of this book with comments written by a scientist to make it easier to understand.

I decided to learn physics but it would be fair to say that I don't know much about it. Fortunately, I have done some calculus when I was in college. So, I don't instantly freeze up and cringe when I see some math. Nevertheless,I want to use "user-friendly" resources to start learning physics. I...

In the outer space, how does gas like this get ignited?

Thanks for all the contributions.

Thanks Dave, I'm re-reading what you wrote but frankly have hard time understanding. I don't seem to get the picture. I'd be among the most noob-kind-of-guys in this forum. Would you mind rephrasing it? The universe is expanding at a greater speed of the light. I guess it's possible because the...

Thank you. I supposed that 186000 miles/sec is the speed of the light. Anyway, could you distinguish the difference between movement and traveling? Because they sound the same to me. If one thing moves at a certain speed sounds the same as one thing travels at a certain speed. I don't have much...

I did some digging and found that it only appears to be faster (an optical illusion?). I still don't understand how and how it relates to the theory of relativity. http://www.answers.com/topic/superluminal-motion

Homework Statement A friend of mine taking physics course told me about this but I didn't understand it because she wasn't able to explain the ideas easy enough for me to understand. All I know is that nothing can travel faster than the speed of light and how's it even possible? The theory of...
