SWR vs. Resonance; Heaviside

WARNING: MORE OFF TOPIC With the greatest respect, what Mr. Maxwell produced, so very earlyon, was a brilliant insight. It was, however, indigestible but for a few. Maxwell's four equations are, really, Oliver Heaviside's four equations. Heaviside was a man without a formal background. Nonetheless, he wasone of the few who did understand Maxwell's jungle of ideas and "built" his own mathematics to express Maxwell's thesis. (For doing so, Mr. Heaviside was excoriated by his "betters", learned gentlemen all, at first, for having the temerity to fabricate a "do-it-yourself" mathematics that he could not seat upon a formal basis. Heaviside answered his critics by saying, essentially,"It works, you figure it out!") After all, that's what our VNAs are all about: measuring RF energy-- |

Yes, Oliver Heaviside is another of our little known doyens of the electronics world. He was indeed a remarkable man. Most of us would only know his name, let alone of his existence, if we are involved in amateur radio or radio physics through the naming of the "Heaviside layer" or "E layer" in the ionosphere. I put Oliver Heaviside in the same category as Nicola Tesla as two of the most under rated contributors to our understanding of the science of electricity and RF propagation. Just my 2c worth...

Most people are not aware of the debt we owe to Oliver Heaviside (who died in poverty, by the way) and assume that the equations we know as Maxwell's were expressed in their current form by Maxwell. Not so. For a very good read, check out "The Maxwellians", by Bruce J. Hunt. And for a short but good read on the development of Vector Analysis, check out this link: https://worrydream.com/refs/Crowe_2002_-_History_Of_Vector_Analysis.pdf - Jeff, k6jca |
I'll just copy/paste from a DM from one of members on this forum. No attribution, not sure if they'd like me to "name names", but content is worth sharing :)
"...the Telegrapher's equation comes from Oliver Heaviside, a self taught mathematician. Is it called the Telegrapher's Equation because it was given to us by a telegrapher? Heaviside was a telegrapher (you know, sending telegrams on the wire) and he was curious to how the telegraph worked, and his work on submarine cables was formative." |
