Can I use different fonts, symbols, font size, or sub/superscripts in Grace?

Yes, Grace has all these features. Wherever you can type a text in Grace, e.g. Axis labels, graph title, text from Plot->Drawing objects, etc., you can use all those features within the same text. Please refer to the User Guide (question User's Guide) for details.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
