Whatever happened to having space stations rotate to create a sense of gravity?

No. The presence or absence of gravity has no affect on the breaking strength of pencil tips. However, it might have an affect on how astronauts use pencils.

Maybe they sometimes press on them harder than down on Earth.

No, it makes no difference. Graphite spinters, period. It's just that it's so small that you don't usually notice the debris.

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.
