M6 is the diameter of the thread and not the hex head. 1 is the pitch of the thread, in other words one millimetre distance between the crest of any two adjacent threads. 100mm is obviously the length in millimetres.
Ask for M6 x 1 x 100mm. Just remember that a bolt with 1.5 thread pitch will not fit a 1mm thread pitch nut. In other words M6 x 1 x 100mm is not the same as M6 x 1.5 x 100mm.
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.
