I am in the research field and am new to the world of Tex and find it really fascinating.
I never knew about this, until I was asked to write my research results as tex files, that is in the LaTeX format.
Then I started finding LaTeX in other places too, for instance in the stack exchange sites.
I just find it as a documentation tool for documenting research work and sites like this. Other than this I would like to know for what other purposes/applications or applications does LaTeX serve?
