"Entropy is a property of matter that measures the degree of randomization or disorder at the microscopic level", at least when considering the second law.
Right, but the very interesting thing is it turns out that what's random to me might not be random to you! And the reason that "microscopic" is included is because that's a shorthand for "information you probably don't have about a system, because your eyes aren't that good, or even if they are, your brain ignored the fine details anyway."
