I majored in physics for a while and did a fair amount of math. The article summarizes current extrapolation from the original laws of thermodynamics very nicely.
Someone else claimed that without Darwin we would have no modern science. Preposterous. I'm not aware that Darwinism has added anything to the advancement of science, other than limited understanding of intraspecies evolution. But from a practical point of view, Mendel contributed a good deal more.
Agreed. Darwin was a great observer of biological entities on his trip in the Beagle, and made some interesting hypotheses, but you are right -- Mendel was much more important to biological science than Darwin.
