Please don't again waste the extra time it takes to write a comment. Instead, think this through. Who would be more likely to believe you can charge a phone in a microwave? 1) People who've been to universities, many of whom know all about microwaves as well as engineering, English literature, mathematics, or city planning? Or 2) people who didn't go to universities?
As to Leif Erikson's discovery of America, he did. The article did not address whether something came of this that you know about and found important. Many events in history were relatively unimportant to the human race; that doesn't mean they didn't happen.
Are you just feeling argumentative for some reason?
