Log@x means Log[x]. Both notations do the same thing.

While I cannot speak for DrMajorBob, my reason for using the
notation f@x rather than f[x] is primarily readability. Constrast

Sqrt[Abs[Sin[x]]]

with Sqrt[Abs@Sin@x]

Both do the same, but for me, it is easier to see what the
second form does than the first. Deeply nested brackets are more
difficult for me to read. And there is the additional factor of
less typing required for the second form.
