Which is better mechanical engineering or computer science engineering?

Go with what you enjoy most. The pay for both can actually be very good so just go with what you feel comfortable with. Both can have you earning over $100 thousand a year, but you won't get this much at the very beginning.

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.
