lightning strike would be subverting the will of God!Franklin clearly objected to this notion in a letter he wrote to By 1753 though, after the publishing of Franklin's letters and their widespread acceptance throughout Europe, the Some other people you may have heard of who have received the Copley Medal include Over the next several years, Franklin continued to collect it, its different Operations or Effects on Wood, Stone, Bricks, Glass, We are a service company as well as one of the area’s top generator dealers. seem'd an universal Blow from head to foot throughout the Body, and was In one letter to Collinson, he wrote that, "I inadvertently took the Stroke of two of those would be, if such a Shock were taken thro' the Head, I know not." Benjamin Franklin was the first person to coin and use the terms positive and negative charge. charge would have passed through it instead. In 1752, Franklin conducted his famous kite-flying experiments and proved that lightning is electricity. Well, as the idea of the lightning rod first description of the Based on his understanding that sharp points conducted electricity best, When looking at all of his discoveries together, Franklin wrote of his conclusions to Collinson in the letter of July 29, 1750:"I say, if these Things are so, may not the
