Uhhh huh. Why is it Tesla is the center of so many conspiracy theories? Einstien is the most famous physicist of the 20th century, and he's only in a couple.
Ok, Einstien was far more important than Tesla. His papers on Brownian motion and the photoelectric effect alone were very important, but his real accomplishment was Special and General Relativity, which replaced newtons theory of gravitation and allowed for the understanding of the universe on a large scale.
I'm pretty sure Tesla did not invent the radio, and I dont know what "Improved lightning" would actually be. How do you improve a natural phenonemon?
And if you rank Tessa so highly, what about other physicsts? What about Bohr, Schrodenger, Hiesenburg, Plank? These physicts were hugely important, I would be curious as to how you would rate them.
