At school I remember being very impressed when I learned that mountaineers climbing Everest couldn't make decent tea because the water never got hot enough -------! Broadly speaking, the temperature at which water boils varies with the atmospheric pressure, and the atmospheric pressure varies inversely with the height above sea level. This means that water at 900 m above sea level boils at a lower temperature than water at 9 m above sea level - so your egg would take longer to cook up there!
You'd need the maths to work things out more precisely, but this might be as much as you need to know? Hope it gets you started, anyway.
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.
