I see, my teacher did mention that we would need Calculus to understand, I'm not there yet. Thank you all for the answers!

Well is there another more complete formula for this? I remember my teacher saying something about the "real" thermal dilation formula that comes from a theorem, but I can't find anything in my notes.

Considering the linear thermal dilation formula ΔL=Li*a*ΔT (length change equals initial length times thermal dilation coefficient times temperature change), I was wondering why does it not work backwards? am I using it wrong or is there something missing? For instance if we assume a=5*10^-5 ...
