God Loves you enough to BURN YOU WITH FIRE!: Transcript

August 16, 2014

Many thanks to Linda for providing this transcript!

[0:00] Thunderf00t: You know, I can put up with A LOT of fiction in a good story. Like blue god-like quantum men, or hundred year old girls fighting werewolves in subways. Or, people in computer games who can stop bullets if they believe it, and so on. However what I can’t take, even in a fantasy, is internal inconsistency. Like say, for instance when these agents—they can punch through walls—and they wanna kill everyone in this car, and this is what happens when he jumps on the first car; he utterly destroys it. And of course, that’s what happens when he jumps on the car with everyone in it he’s trying to kill, right? Nah, he just nimbly lands on the hood, merely making a mess of the paintwork, and so on.

[0:42] Or the time where the car he wasn’t trying to kill the people in is a mangled, bullet time wreck. In films, these are just kind of annoying and they’re called plot holes—it’s an internal inconsistency, and it’s the hallmark of bullshit. And people who can hold these internal inconsistencies in their mind in the real world—and even justify them—are idiots.

[1:05] So, let me just give you an example like: ‘my boyfriend only beats me because he loves me so much.’ Actually, no that’s a bad example because that’s pretty emotionally driven. Let me give you another example, that ‘God loves me so much, that he will torture me for eternity if I don’t do what he says.

[1:24] Huh, now that’s exactly the same thing just for the fictional character. Now it’s just come to me. I’ve got a famous example of this. Like when John Paul II claimed that it was a miracle that saved him from dying when he was shot, and that it was the Lady of Fatima who diverted the bullet away from a critical artery. To which Richard Dawkins famously retorted in The God Delusion that:

[1:48] clip from “Richard Dawkins Reads The God Delusion”: “When he suffered an assassination attempt in Rome, and attributed his survival to intervention by Lady of Fatima, “her maternal hand guided the bullet”. One cannot help wondering why she didn’t guide it to miss him altogether. Others might think the team of surgeons who operated on him for six hours deserve at least a share of credit.”

[2:19] Thunderf00t: Hell, if he wanted a miracle thing, why didn’t he just make like Neo? I mean believe me, if the Pope could do this, there would be a hell of a lot more Catholics in the wide world. But the reason I bring all this up is ‘cos this YouTube video I saw the other day.

[2:35] The creationist Kent Hovind is currently in jail after being convicted on a host of federal offenses mostly related to not paying his taxes. In fact, he’s been in jail for the best part of the last ten years. So some of the religious folks were discussing this:

[2:50] clip from “New 911 EMERGENCY! Dr. Kent Hovind 07/10/2014 Truth Serum Talk Radio Show Club Creation”: “And if you’re not everyone, priest [?] please lift him up in prayer. God has kept his hand of protection on Kent. Kent has been with some of the most violent offenders in this nation, and he’s not been harmed.”
“Mmhmm. Yes, exactly. And that just shows you the power of the Holy Spirit and the power of God at work here.”

[3:13] Thunderf00t: So did you get that? The fact that Kent has not been harmed in jail—just like tens of thousands of other prisoners who haven’t been harmed in jail—is actually the work of god. However, it would seem that even though god is powerful enough to keep Kent safe in prison, he’s not quite powerful enough to free him from prison.

[3:33] clip from “New 911 EMERGENCY! Dr. Kent Hovind 07/10/2014 Truth Serum Talk Radio Show Club Creation”: “But then again, you know, we do have an enemy and it’s not flesh and blood. Our adversary is the Devil and it’s his objective, um, to clearly to shut Dr. Hovind up and lock him away from the world so he can’t continue winning souls.”

[3:50] Thuderf00t: I mean, really, an all-powerful being who you think has personally intervened to keep you safe in jail, can’t get one man out of jail. I mean DAMN, the sheer self-centeredness of it all. If you’re gonna pray for something, DAMN pray for an end to childhood cancer! Not to get Kent Hovind out of jail. Or even better—get off your knees and actually DO something. ‘Cos as the old saying goes, a single pair of hands at work achieves more than a billion clasped in prayer.

Why is Potassium gas Green?

June 18, 2011

So my interest was really spiked here when I found that when reacting with water, potassium gives off a green gas!

While the green of potassium gas has been known about for over a century, being found in Encyclopedia Britianica articles as far back as 1911, the origin of that green color is proving a little more elusive.

If you know what you are doing it’s relatively easy to observe.  250 mg of potassium is ‘the right’ scale to work with.  Much smaller and it’s all over before you get a chance to do anything, much bigger and you run into problems with the metal exploding, or the hazards of hydrogen build-up.  All you need is a heavy glass vessel of about the dimensions of a wine glass.  Insert a burning acetone taper through a small hole in the top of the vessel and to burn out all the oxygen, and then drop in your potassium.  The green color is easily visible.

I’m tempted to propose it’s due to the solvated electron, which is a hot research topic at the moment as it’s part of the principal mechanism by which radiation damage happens to DNA.  It’s known to be stable and blue in liquid ammonia, but survives only picosecond in water.

It’s an interesting suggestion, but I think the observation that you get the green color when there is no water around pretty much kills this idea.

So how do you get a green gas.  Well the only other metallic gaseous vapor I’ve seen was mercury which I once boiled to test the calibration on a thermocouple.  That has no color at all that I can remember.

Well as you will recall virtually all the gases are colorless, e.g. all the Noble gases (helium, argon etc) and all the first period gases (nitrogen, oxygen, and mostly fluorine).  However the heavier halogens have colored vapors that get more heavily colored as you go down the group.  Chlorine, light green, bromine, brown etc.

Chlorine (left) and bromine (right).

The reason these gases have these colors is the same reason the sky is blue, Rayleigh scattering.  That’s related to the polarizability of the molecule.  This is a very different mechanism from the electronic transitions that give the classical flame colors of the alkali metals!

It’s well known that all the alkali metals have stable bound states as diatomic molecules, similar in electronic configuration to hydrogen.  IF K2 had a similar polarizability to Cl2, it may well be green like chlorine!  Regrettably finding the polarizability K2 is not as easy as it sounds.  A significant difference between H2 and K2 is the bond energy.  H2 has a bond energy of about 400kJ/mol, while K2 has a bond energy of ~50kJ/mol.  For reference, the hydrogen bond, the thing that holds water together as a liquid, has a bond energy of ~20kJ/mol.  If you heat any bound state and eventually the species will gain enough energy to separate and become individual species.  With water this happens at about 100 oC (boiling, ~400 K).  For hydrogen it’s about 3000 K.  You can actually do the real calculations, it’s just I’m too lazy at the moment, and so I’m just going to do a linear extrapolation between these two.  That gives K2 breaking up at about 2-300 oC.

Well that would fit nicely with green gas being evolved at lower temperature, but as the temperature rises, the diatomic species break up, and the relevant polarizability of the molecule, and hence the Rayleigh scattering, and hence the color is lost.

Great, so if this is a working hypothesis, then the diatomic metals should match their corresponding halogen right?  The bummer is sodium.  Sodium gives off a blue vapor when it boils.  Fluorine is almost colorless.  ARSE!

The game is not over yet!

I’ve decided I need to see sodium vapor for myself, but how to do it with only the junk I have to hand!  What I really need is a nice small sealed silica tube that can take temperatures over a thousand degrees C.  Hmmmm, thinking, thinking…..
