He doesn’t like Holden‚ in Catcher in the Rye‚ because he is not a real-life character‚ at least the characters in The Breakfast Club were real to him. Tom Perrotta does not like the ending to the movie and after watching it again he feels that other movies are better in representing teenagers‚ such as Fast

the atoms of Democritus produce the wide range of substances apprehended by our senses. He declares the existence of only four elements: fire‚ air‚ water and earth. All matter is made up of these four elements and matter had four properties: hot‚ cold‚ dry and wet. Greek science in Alexandria: from the 3rd century BC Classical Greece has produced a brilliant tradition of theorists‚ the dreamers of science. Attracted by the intellectual appeal of good theories‚ they are disinclined to engage
