Theoretical Physicist, Brian Greene in a lecture for TED Talk titled, “Making Sense Of String Theory” claims that Theoretical Physics has had a major break through in research called Superstring Theory. Greene supports his claims by giving a historic background on Superstring Theory and how it came to be. Greenes purpose is to persuade and inform his listeners that Superstring Theory exists and how science plans to prove it. Brian Greene delivers his lecture in a humorous, formal, scholarly tone. His intended audience is anyone interested in physics that isn’t necessarily a physicist.
