Since there hasn't been a question here in a while, I'll ask a common beginner's quantum question:
From Planck's Blackbody Radiation Equation, one can derive Stefan's Law which is: e_{total}=a*s*T^{4} where e_{total} is the energy per unit area, s is a constant: 5.67X10^8 W*m^{2}*K^{4}, and a is a coefficient that equals one when dealing with an ideal blackbody.
Using:

Where C_{1} is 8*pi*c*h and C_{2} is h*c/k_{b}
Show the relationship between temperature and lambda max. Find the constant s discussed above using this relationship.
I'll be posting more hints if anyone tries.

I remember solving this along time ago?

Yes, you did... its included with most texts introducing quantum mechanics.
