By charitable reading, it's not what ze's saying.
From the standpoint of a person making discoveries, it is known from many observations that Bob the Particle will always Wag. Thus, "Bob Wags" is stated as a Natural Law, and assumed true in all calculations, and said with force of conviction, and if some math implies that Bob didn't Wag, the first thing to look for is errors in the math.
However, still from the same standpoint, if some day we discover in some experiment that Bob didn't Wag, and despite looking and looking they can't find any errors in the math (or the experiment, etc.), then they have to conclude that maybe "Bob Wags" is not fully true. Maybe then they'll discover that in this experiment, it just so happens that Julie the Particle was Hopping. Thus, our hypothetical discoverer rewrites the "law" as: "Bob Wags unless Julie Hops"
Maybe, in some "ultimate" computation of the universe, the "True" rule is that "Bob Wags unless someone else Leers, and no one Leers when Julie Hops". How do we know? How will we know when we've discovered the "true" rules? Right now, we don't know. As far as we know, we'll never know any "true" rules.
But it all boils down to: The universe has been following one set of (unknown) rules since the end of time and forever 'till the end of time (ha! there's probably no such thing as "time" in those rules, mind you!), and maybe those rules are such that Bob will Wink when we make John Laugh, and then we'll invent turbines and build computers and discuss the nature of natural laws on internet forums. And maybe in our "natural laws" it's impossible for Bob to Wink, and we think turbines work because we make Julie Hop and have Cody Scribble when Bob doesn't Wag to stop him. And some day, we'll stumble on some case where Cody Scribbles, Bob doesn't Wag, but Bob doesn't Wink either, and we'll figure out that, oh no!, the natural laws changed and now turbines function on Bob Winks instead of Cody Scribbles, and we have to rethink everything!
The universe doesn't care. Bob was Winking all along, and we just assumed it was the Cody Scribbles because we didn't know about Annie. And never there was a case where Bob Wagged and Winked at the same time, or where Bob failed to Wag when Julie Hopped. We just thought the wrong things.
And if in the future we'll discover other such cases, it's only because the universe has been doing those things all along, but we just don't see them yet.
And it's even possible that in the future Bob will marry Julie and then never again Wink... but all that means is that the rules were in fact "Bob Winks when Annie Nods unless Bob is Married to Julie", rather than "Bob Winks when Annie Nods", and yet our scientists will cry "The laws of physics have changed!" while everyone else panics about our precious turbines no longer working all of a sudden.
Hmm, if I understand you correctly, you're saying that the universe does obey natural laws (not necessarily the ones we think of as laws, of course) in the sense that if we were to understand the universe completely, we would see that there are physical impossibilities (that aren't logical impossibilities).
Maybe that is what Slider was saying, and it's certainly implied by "You can't use the laws to compel events, an attourney is of no use. If something that contradicts with a law happens the law is just proven false." But forgive me if I misund...

Thinking about it, I realized that this might be a common concern. There are probably plenty of people who've looked at various more-or-less technical or jargony Less Wrong posts, tried understanding them, and then given up (without posting a comment explaining their confusion).
So I figured that it might be good to have a thread where you can ask for explanations for any Less Wrong post that you didn't understand and would like to, but don't want to directly comment on for any reason (e.g. because you're feeling embarassed, because the post is too old to attract much traffic, etc.). In the spirit of various Stupid Questions threads, you're explicitly encouraged to ask even for the kinds of explanations that you feel you "should" get even yourself, or where you feel like you could get it if you just put in the effort (but then never did).
You can ask to have some specific confusing term or analogy explained, or to get the main content of a post briefly summarized in plain English and without jargon, or anything else. (Of course, there are some posts that simply cannot be explained in non-technical terms, such as the ones in the Quantum Mechanics sequence.) And of course, you're encouraged to provide explanations to others!
