I was reading the concept of fiber bundles in differential geometry , I am really confused about the whole lot of maps and am not at all getting the picture.. can someone please give me an intuitive idea so that i do not have to carry the definition in my head? My specific confusion is the difference between the fiber space F and the Fiber bundle E (sometimes called total space)..sometimes I find the word "typical fiber F " also .. and how the structure group is acting ..I will really appreciate any help.. it will also help me if someone directs me to some good source in the web.. thanks.
