Learn and Understand the Theory of Relativity

Surely, you have heard the story of the astronaut coming backto earth, looking as young and fit as when he left, witheverybody else on earth hardly being able to walk because ofthe years added to their age, as a result of the difference inhow time passed on Earth as opposed to the time passingover the astronaut. Many would argue that this is just anillusion, when in fact, although not literally true, there is ascientific explanation for this: indeed, you must have guessed itby now, Einstein's theory of relativity is perfectly applicable andit is Einstein's Theory of Relativity we need to resort to inorder to not only explain such hypothetical cases as this one, but also understand the particularities of the world we live in.
Upon mentioning Einstein and his famous Theory of Relativity, the first thing that comes to one's mind is the notorious E=mc2 However, there is more to the theory of relativity than this:in addition to the implications concerning mass and energy, itimplies further several areas, such as, among others: space, time, and gravity. We invite you to join us on our journeythrough the main points of Einstein's Theory of Relativity.
Thisbooklet is, thus, intended to show beginners to a brief andexplanatory introduction to Einstein's Theory of Relativity -what it means, how Einstein got to develop it, its ramifications, as well as its applications and implications to present scienceand our lives as we know them.
