**Introduction**

#### In 1905, Albert Einstein submitted five scientific papers to the
German periodical Annalen der Physik. Three of these in particular proved to advance markedly different aspects of physics although one of them, entitled 'On The Electrodynamics of Moving Bodies', was to
resolve a most fundamental quandary concerning the nature of physical reality. By accepting the
validity of certain experimental results, he found the only logical path available to resolve an
apparent inconsistency. From this paper
would emerge the theory of Special Relativity, although not yet formulated in that explicit
phrase. It dealt with the uniform motion of bodies over space and time. [His other papers proved fundamental in understanding Brownian Movement, the relation between Mass amd Energy (in E=mc2) and Quantum Theory.]

Ten years later, he advanced his theory of General Relativity, which
could account for both uniform and accelerated motion, particularly that due to the force
of gravity. For many years, it provided the most
promising basis for incorporating all laws of nature into one consistent model (albeit leaving quatum mechanics aside). To
understand it fully probably requires more mathematical (and conceptual) ability than this writer possesses.
But the special theory of relativity should prove more amenable to such comprehension, without too much
mathematical knowledge. This section of the Website is thus devoted to my attempts to write out the
strands of ideas that led to the conclusions Einstein arrived at in this regard in 1905, at least, and by this
means try to understand those conclusions. Such ideas go back a long way of course and some of
these will have to be described more superficially than, hopefully, the later ones. But verbal
concepts and descriptions can never be as succinct and economical (ie elegant) as can mathematical
and physical equations when distilling such truths. Indeed, when writing out the ideas that I've
read about and struggled with, I find I generally go on much too long - which is another way of saying
I probably don't yet really understand what I'm seeking to explain (to myself!) Nevertheless, this
is my attempt.. The following are probably best read in sequence but can be considered separately in any order.
