Suppose L\sum* = L for an alphabet \sum . What can we say about the possible strings in L? I know that the \sum* is a collection of all possible words of a language and I know that 'L' is a subset of \sum* . So L concatenated with \sum* needs to be equivalent to L. I am stumped.

Many people within the field say it's not a science nor a subject to do with computers. Then why keep it with the name computer science. What's stopping them from changing the darn name?
