No doubt there is a very strong relation between them. There's no situation where the availability to do work goes up if entropy goes up.
I probably would've stated it's related to the availability of a system's energy to do work and not that it IS that availability. Or I would have said it's the inavailability of that system's energy to do work.
I wasn't kidding when I said I was nitpicking. It's clear, regardless of symantics that you know what you're talking about:). Hence solid A.
I would also give you a good grade. Perhaps not an A+, but it would be no less than an A-. The only "error" I saw was really your definition of entropy (I assure you, I'm really nitpicking here).
If entropy was "the availability of a system's energy to do work" and 2nd law stated "entropy must stay the same or increase" then that means the availability of a system's energy to do work would increase over time (quite the opposite is true). That's why I never liked that definition. Solid A.
I had seen the first vid before. It's one of my favourite of Harris. The second vid is new to me though. Thanks for those. I quite enjoy Sam Harris's lectures.

Wait, you're right. I stand corrected. A better definition is; Entropy is a measure of the energy that is not available for work.

Thanks for the tip. It's good to have better definitions for things.

yup.
A+
Let me guess - you're an atheist?
(I ask because so far, only atheists have been able to 'pass the test')

I'm always reluctant to use the word atheist. It has too many connotations attached to it, but yes, I guess most people would describe me as such.

I know what you mean, and it's something I wrestle with.
Check out these vids by Sam Harris for more on the topic (he is of the opinion that we should perhaps drop the word altogether):
