- I am very glad that you replied to this article, it was very needed. However, I don't think you should not have agreed with the response "inventions are made in the context of scientific and engineering understanding." While it is true, Edison clearly had no engineering understanding. Edison's patent stated that the carbon filament could be created using "cotton and linen thread, wood splints, papers coiled in various ways,"
- I hope it is obvious how ridiculous this is.
Also, considering that his patent was on using a carbon filament, and the first lightbulb used charcoal 70 years before Edison, I am not sure how he got the patent anyways.
Lastly, I am sad you did not include Tesla's opinion of Edison's work. "If he had a needle to find in a haystack he would not stop to reason where it was most likely to be, but would proceed at once with the feverish diligence of a bee, to examine straw after straw until he found the object of his search. I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90% of the labor."
Edison was not an engineer, he relied solely on empirical observation.
