There's a brand new page called "What is Cosmology?", giving a quick history of the topic. Check under the Cosmology tab on the left.

It is hard to find a good technical book on relativity that is "digestible" by engineers. It became my passion - almost an obsession - to find at least one completely understandable technical book on the theory. The "old man" above-right would probably just have chuckled... (Einstein 1947. Photo from Wikipedia)

In publications on Einstein's theory of relativity, the popular book is usually too popular and the technical book too technical, with nothing in-between. This eBook and website bridge that gap in a way that will satisfy your engineering curiosity. At the same time, the inevitable mathematics are kept within your engineering "comfort zone".

I invite you to scan through the very comprehensible pages of this website and it's downloads and add the eBook to your collection. You may still look at Einstein's theory of relativity with admiration, but never in the same way again!

Us engineers always love that 'this-is-under-control' feeling. With Einstein's theory of relativity, it happens as soon as we are confidently doing some relativistic calculations. How would you rate the capability of doing the 'sums' for high-speed space travel, linear acceleration to relativistic speeds, orbits near black holes, the age and shape of the universe? Pretty cool!

Do not bother to look in this website for a 'new theory of gravity', a 'new theory of everything' or the "final theory". I offer only standard mainstream relativity and cosmology with an 'engineering voice and spin'.
