The theoretical and the analogue real world imbalance

The vast majority of why the technically sound of reasoning, mathematically perfect and physics theory compliant fail to deliver as presented in literal mirror fashion once implemented is easily explained and summarised as :-

 Most mathematically sound core principle and physics compliant theoretically sound ideas and subsequent designs are built on an amalgam of theory in lab rat perfect characteristics and cause and effect in an environment that doesn't actually exist.

Where in the physical world, there's a seemingly infinite number of factors and influences that cause things to not literally mirror the ideals of the lab rat stable virtual model environment.

If you could take any theoretical sound and physics stable idea, build it and it just works out of the box with equal stability and efficiency, just about every crazy fringe ideas that ever failed would have hit the ground running as a going concern.

This is why designs go through many iterations of a wide range of narrow and wide variations gained from testing various aspects in the real world and the knowledge and findings become the knowledge base that allows a much more accurate model environment as a core virtual base to work within, so your iterations of change and variations and what-if exploration become much more likely to be somewhat valid or extremely so once proof of principle turned into a working model in the RW becomes more likely.

The real world is a collision of some fairly stable characteristics, a crap load of consequential intentionally and unintentionally crested effects and further causes that all have a cascaded result of many cascading factors.

And that sums up the physical basis of why you finds more 'ooops' factors and calamities when try stuff than get a fast-track to getting a sound idea to work out of the box.

I posted this because we, as radio user/tinkerers and sometimes mad inventors are working with invisible intangibles frequently that we've still barely scratched the surface of comprehensively understanding and really effectively exploiting with a very large undiscovered country scope, so whilst it's no surprise we often get caught out with gremlins in what we do, it's the blind hope and optimistic blind faith that's often as fault because we really don't go out of our way to embrace the realities we're part of.
