comment Polynomial expansion of operator
You can make it more efficient by using NestList as in Simplify[Total[NestList[L, f[x, y], 3]]].

May I ask why you would want to do that rather than simply opening your notebook outside the Workbench ?

comment Find 2 points in a normal distribution with these given properties
Define your distribution without PDF and try FindRoot. Also, you might take advantage of the symmetry of your distribution around the mean.

comment Equation Solving
I would do : vars = {q[1], q[2], q[3], q[4], q[5], q[6], q[7], q[8], q[9], q[10], q[11], q[12], q[13]}; equal = {q[2] == 3*10^-4}; inequal = Abs[#] < 10^(-4) & /@ vars[[3 ;;]]; sol = NSolve[Join[eqns, equal, inequal], vars, Reals]
