Jesus, you're a dumbshit. (That's just a statement of opinion. But an honest one.)
I told you before I'm not going to tell you why you're wrong. But here's another hint you don't deserve: I don't dispute your Equation 1, and never have (in a hypothetical ideal context, that is). You're just applying it in a way that doesn't actually apply.
I admit that it took me a while to figure that out when originally presented with this idea (which was a few years ago now). But I did, and I'm no physicist. However, there are physicists (like Joe Postma, for example) who might be happy to explain it to you if, that is, you don't piss him off (or haven't already pissed him off) with your adolescent, antisocial behavior.
And no, your ad-hominem explanation of why you won't confront the actual engineer who made the argument won't wash. First, it *is* ad-hominem... not in the context of your scientific argument, but in the context of why you refuse to make your argument to the proper parties. So no, I did not "misuse" the phrase ad hominem. It was part of your argument, so it applies. Not to mention that it's just plain bullshit anyway.
Go ahead, keep making a fool of yourself. I'm happy to let you do it.
