I m a biology major and I just want to take something into the lab and dissect II. Professor Blake Fair enough. Ellen Q5o But I m a physics major and . the idea of a theory of everything appeals to me. I know that we cant observe strings . yet. but maybe that s just a problem with the technology and . and eventually we may be able to observe strings in the laboratory or. or we could find a way to observe strings in a natural setting and .

Professor Blake Well in fairness any new theory has to begin as conjecture but the real question is can string theory pass through the developmental stages to a point where it can be verified or rejected. And uh these developments could be in the area of technology like Ellen suggests or perhaps they could be new methods of performing calculations and uh. deriving the mathematical predictions. What I m going to suggest is that we take a look at the web site that supplements your textbook. There are videos as well as animations and it includes a really good history of string theory uh but that s not why I want you to see it. I think the site demonstrates where we need to go from here if we re going to pursue an ultimate 05 1 theory a a theory of everything if you will And it s fairly objective so it should provide us with some ---- Interesting data for both sides of the debate.
