I received an e-mail from a colleague of ours in Oregon that is pretty cute. ;-)
dear Mr Motl
My name is [A. K.]. I am in grade 4 [10 years] and live in Oregon. My teacher said in class something on particles we are made of. I asked her more about particles but she did not say more.
I used google to search for more on particles and saw strings as what particles are made of. I used google to look for more on strings which showed a book by Brian Green and Micho Kaku. I got my dad to get me the Green and Kaku books. The Green book is harder to read. The Kaku book is easier. I find neat is how the world is made up of particle and small strings. I ask my dad and mom for more on strings. They did not know much.
I want to know more on strings. Some string web pages look like math I dont know. I want to do strings with math. The Green Kaku books do not have the math I saw on some string web pages. My dad says the math is algebar and calculus. He got me the books algebra for dummies and calculus for dummies. In some pages I can get answers from moving symbols around. I do not know why I get the right answers. I do not see how the math is done in strings. There is alot Kaku and Green do not say?
I used google to find more on strings and saw your name on lots of web pages on strings. I want to do strings when I am older. How do I go and do strings? What do I have to do? Do people do strings for a job?
School is very boring and easy. Particles and strings look exciting and neat to me. I want to learn more. I have nothing to do outside school. What did you do to learn strings?
