Couldn't resist the snowclone earlier on :)
At the point where the "very clever alien" has raised a load of my relatives from the dead, destroyed galaxies on a whim, made Saturn appear and disappear, reversed the expansion of the universe, turning all measurable red-shifts into measurable blue-shifts, and passed all other conceivable empirical tests of godhood, I think I'd stop the philosophical musing about what constitutes a god and start kissing his little green ass.

The (Roman Catholic) Church in Ireland lost whatever respect they might have had when their facilitation of child rapists amongst the clergy became public knowledge. That they shirked even the civil liability for these crimes, with a disgusting immunity deal with the State, which made the Irish tax-payer financially liable for the rape of children perpetrated by priests, invited the opprobrium of every person with a shred of integrity on both the Church and the corrupt scumbag politicians, still in power, who brokered the deal.
Shame on the whole damn lot of them. I wish there was a hell for them to burn in.

Honestly, anyone who trots out this hoary old chestnut equating religion -- with bell, book, and candle -- and simple disbelief -- for want of evidence -- should be ashamed.
I'm sure Richard would have no problem setting up an experimental "obstacle course" for a deity. Making Saturn appear and disappear when I click my fingers would be a decent start. Making the light from a laser pointer bend in a circle around my finger would be pretty convincing. Making all of the stars in a distant, but observable, galaxy appear, on Earth right now, to go supernova on cue would be very impressive. Lots of witnesses and videotape required.

Roland_F,
I'm always interested in things that are correlated with religiosity (I hate that word). I'll add promine to temporal lobe epilepsy and psychosis on my list.

No (dammit :), I didn't define verifiable as provable in logic, if you reread my comment you will notice I stated that nothing can be verified except logical inferences: Presupposing axioms, inference rules and premises, the conclusion can be verified.
But let's not dwell on this, I'd be much more interested in how you would define "to verify"...?

My point was that we would be -strictly speaking- lying using the term "objectively verified" or "verifiable" in connection with theories of empirical sciences, and I for one think we shouldn't lie.

Comment #129889 by emmet on February 19, 2008 at 6:04 pm
MPhil,
I take your point, but I think you're missing mine and, perhaps, being a little pedantic.
The point I was trying to make is that debating with religious zealots using terms like "true" --- which are highly ambiguous and vulnerable to sophistry in common usage like, "Well, that depends on what you mean by 'true'!" or, "Well, do you mean scientific truth, emotional truth, or religious truth?" --- is flogging a dead horse. You need only listen to Madeleine Bunting's staggering "What do you mean by 'believe'?" in the Guardian Debate the other day to understand how utterly bizarre this kind of sophistry becomes.
The myth-peddlars unashamedly steal scientific terminology without the slightest notion of what it means: one of Richard's TV documentaries ("The Enemies of Reason", IIRC) shows how faith-healers and crystal-mongers have adopted "quantum" and "DNA".
Given these two facts, which I assert without evidence by fiat ;o), I think it's desirable to change the language of our discourse with "them" to something that has a strong common-language meaning that's less amenable to being "interpreted" into vacuousness as "true" and "believe" have been.
What I'm seeking is a "strong" alternative to "true" to avoid confusion; I'm not wedded to the particular term "objectively verifiable". I do see your point, but "extremely well corroborated" sounds far too weak. "God exists" can be argued to be "extremely well corroborated", since millions of people will "corroborate" such a statement. I think even "objectively verifiable" is a stronger assertion notwithstanding your objection to the definition of "verifiable" in terms of "true".
If we are asked what we mean by "objectively verifiable", then we can explain the concept of falsifiability and the role of experimental evidence and observations in corroborating a theory. And while your final sentence is, to my understanding, a fair synopsis of the fundamentals of proof theory, that is not the field on which the game is played. In the spirit of "don't educate the market" (unless they ask for it), I would consider a term like "objectively verifiable" to be a valuable rhetorical device.

Comment #129369 by emmet on February 19, 2008 at 3:06 am
It was very hard to watch, like torture.
The 7 year old Floridian boy's story was particularly disturbing to me: "saved" at the age of 3, his father having terrorised him by telling him that he was going to hell for not obeying his parents. We can only imagine how vivid a picture of hell was created in the child's mind between beatings. To see him "preaching" words that he could not possibly understand made me cringe.
These children do what they do because they have been trained, like Pavlov's dogs, that it's a sure-fire way, maybe the only way, of getting positive attention from their parents. That huge crowds of people turn up to see and hear these poor brainwashed children, and think it's OK, disturbs me.
On the other hand, I think there was some cause for hope: the security man saying, "It's a shame that you bring your son into this too, sir" and the incredulity and ridicule from the crowds in New York. Too often, I think, we tar "the Americans" with the same brush and assume that, with the exception of a small minority, they would approve of this sort of thing. Not so, it seems.

Comment #124098 by emmet on February 8, 2008 at 11:09 am
I actually think I know what's happened here, and it's very sad.
I suspect that the guy thinks that the potential difference that he measures across the terminals of a generator means that the generator is "connected" or "engaged", and that short-circuiting the generator is equivalent to "disconnecting it". He further thinks that "back-EMF" means something like "magnetic field". If you watch the videos bearing these caveats in mind, they make a LOT more sense and you're left with a very uncomfortable tragi-comic feeling of pity for a man who has ruined his life over a pretty basic, but understandable, freshman's misconception that could have been corrected with a basic course in "electric machines" 20 years ago.
By way of explanation, the "wheel of magnets" causes a changing magnetic field in the vicinity of the (1 to 7) coils arranged around its periphery. When the coils are shorted, a current is induced in the coils by Faraday's Law of Induction; this current, flowing in the wire of the coils, dissipates energy as heat due to resistive heating of the wire, and the wheel slows down. When the coils are NOT short-circuited, a potential difference develops across the terminals of each coil (this *IS* what was called "back EMF"), but no significant current will flow, little or no energy is dissipated in the coils, and there is no braking effect.
Accordingly, what is observed in the videos is exactly what one would expect from a sound understanding of basic physics: he is running between 1 and 7 little generators off the driveshaft. When he connects the two ends of a coil together, what I'd call "shorting the coil", he calls it "disconnecting the coil" (this is made clear in the 2nd "Part 3" video). Huh? That's not "disconnecting" anything, it's completing a circuit allowing the induced current in the coil to flow. It *isn't* a surprise that the motor slows down.
A "back EMF" (a largely deprecated term a bit like "cathode ray") is the potential difference which appears between the ends of a coil (in a motor or a generator, for example) by virtue of the changes in the flux cutting the coil (either by movement of the coil in a static magnetic field or by a time-dependent magnetic field). The parts about a "back EMF in the air-gap" being "magnetically coupled" in the drive-shaft are simply rubbish: the term "back EMF" doesn't mean what this guy thinks it means and even what that might be is not clear. This isn't the end of the, to be charitable, "terminological inexactitude": his toroids are not toroidal; he plainly has no understanding of magnetic reluctance; he uses "loaded" and "unloaded" exactly backwards; and thinks shorting a coil "disconnects" it in some
way.
On a relatively minor point, we simply have no idea what the actual energy consumption of the motor is, since all he appears to do is measure the RMS current with a multimeter. We don't know the power factor of the motor, nor is the phase angle between the applied voltage and the current drawn measured in any way. Thus we don't know how much of the measured current is real and how much is imaginary. TBH, I don't remember much about motors, but (the more basic error notwithstanding), a dependency of the motor's power-factor on rotational speed seems like a much more likely explanation for the small drop in measured current than a "perpetual motion machine".
Now, I'm not saying that the guy definitely didn't observe something interesting (in a phenomenological sense) but the explanatory theory presented in the videos grossly abuses terminology to the degree that it is "not even wrong" (with apologies to Pauli) and probably backwards.
What still leaves me a bit confused is trying to figure out what the "interesting bits" that grabbed the attention of an MIT professor are. I suspect that the good professor erred only in thinking that they had a common understanding of what "disconnect" means, and was prepared to ignore the other abuses of terminology in the interest of seeing whether there mightn't actually be something interesting behind it.

I'll have to do a Groucho Marx: open an account and cancel it in protest.
I'm both appalled at the blatant bigotry and, curiously, quite happy about it: frankly, I think it could be a fantastic recruitment campaign for atheism, giving it instant kudos amongst those who think MySpace is lame.
YouTube seems to be no better, btw. For the last month or so, they have de-listed all atheists from "honours" like "most subscribed", etc.
I wonder if there are any religious (or other) groups with the integrity to denounce the MySpace and YouTube anti-atheist bigotry?

I read somewhere that pigs are not kosher simply because they are lousy herd animals, totally unsuited to the nomadic lifestyle of the Jews at the time, and that the "unhealthy" claims are post-facto rationalisations. The identical Islamic prohibition could easily just be direct plagiarism, since Mohammad seems to have been "inspired" rather a lot by previous religions.
Not sure of the veracity of the above. YMMV.

138. Irreligion: A Mathematician Explains Why the Arguments for God Just Don't Add Up
Comment #109739 by emmet on January 9, 2008 at 3:36 pm
BAEOZ,
The "argument" is plainly circular, not to mention vacuous and stupid.
The problem is that "everything" really means "everything except God": God is implicitly presupposed to exist and excluded from "everything".
Put another way, one can use the conclusion of the argument (God exists) to deny the foundational assumption: if *everything* has a cause, then God has a cause, unless God is not part of "everything" (the implicit presupposition). If God is not part of "everything", then in what sense can he/she/it be held to exist?
TBH, for the sake of your own sanity, I'd avoid getting involved in an argument so manifestly sophomoric and masturbatory, unless you enjoy playing whack-a-moron.
