I participate on this site because I really enjoy physics and because I would like to learn more about what makes an online community work well. Questions often interest me more than answers – although I think the best answers are grounded in observation and experiment. I’m optimistic that there are still many surprising discoveries yet to be made in the physical sciences. I believe physicists should be good citizens. I believe my children will know things about the natural world I can’t even imagine – and will learn them in ways quite different than how I was educated.

comment Can Aluminium be softened
Good catch. The reference figs I linked to are actually shown in F degrees, I wrote C, I corrected the answer. Thanks

comment Effect of CO2 on the environment, besides greenhouse effect and ocean acidification
I think this question needs to be more specific. Are you asking what physical effects (measurable) CO2-concentration has on the atmosphere?
