...ere is what I have so far... a6=0.0 for n1 in -10..10 for n2 in -10..10 for n3 in -10..10 if n1!=0 and n2!=0 and n3!=0 p=Math.sqrt(n1**2+n2**2+n3**2+n1*n2/1.414+n1*n3/1.41+n2*n3/1.414) a6+=(1/p)**6 end end end end puts a6 What I''ve got here is a 10x10x10 face-centered cubic lattice of atoms. What I want to do is find this constant a6= sum(1/Pij)**6. From a starting point I want the distance to every other atom location point in the structure, meanwhile inversing and power to the sixth each distance. Then I want to add all those up. This should re...
