An AAAA cell has 200-350 mohms internal resistance. A 9v battery has 6 of them in series (many of them are literally that, others have their cells as a stack of plastic buckets). The nose ring is a short run of wire, it’s idunno a 0.2 ohm heater?
I just tested this (for science!) with a 9V battery and an iron nail of roughly nose-ring diameter. Both the nail and the battery get unpleasantly hot after several seconds. I don’t think they’d get hot enough to burn you, though. (Don’t take my word, though, please!) I believe the internal resistance of the battery does also increase with the temperature, so it effectively somewhat self regulates itself.
Common nose ring materials like Titanium and Stainless Steel are 4× and 7× more resistant than iron, which means they should dissipate more power than the nail, and thus get hotter. I was calculating something around 3 milliohms for a titanium 16 gauge 10mm wire, and 0.7 milliohms for an iron wire.
Regardless of material, at 1000 milliohms internal resistance, i think the battery itself is doing most of the heat dissipation. (But also over a much bigger surface area!)
About 10-20s, I left it on until it didn’t seem to be getting much hotter. I also didn’t want the battery to overheat and fail catastrophically. I think because the “wire” is such a large gauge, there’s not enough current for it to get seriously hot. In a foam cutter, you’re passing all that current through a much smaller cross-sectional area.
Edit: just to confirm, I did a little math. A 10cm steel wire with a tenth of the diameter would have a resistance of 5 ohms. That means that instead of 1% of the total heat dissipating in the thick wire, 80% of the heat is dissipating in the wire in foam cutter’s case, and there’s more total resistance, so more heat dissipation as well.
This is because:
A = π r²
R = ρ × L / A
So resistance is proportional to the material resistivity (ρ), the length (L), and the inverse square of the radius (r⁻²). That is to say, decreasing the radius by a factor of 10 increases resistance by a factor of 100.
Liberia and Myanmar also use imperial units, but they’re both starting to move towards metric in recent years so soon the US truly will be alone in that
Actually, mormons think they are very logical. I’ve seen many instances of people talking about how Brandon Sanderson being Mormon is why he’s so thorough at world building.
The flaw of the meme isn’t that it’s picking on religion, the flaw of it is that it assumes illogical views negate logical views. Believing that angels hid golden plates in New England doesn’t negate good looks at a P&L in the same way that a Christian working at NASA that believes a dude rose from the dead doesn’t negate good math to get a satellite into space. In the same way that me being agnostic doesn’t mean I’m always logical and rational in every situation.
I argue the opposite and I think the difference is that you believe religious belief can be demarcated in a persons mind where I think it influences all decision making.
I.e. Does my boss make decisions on P&L because they are good at business or because they prayed on it?
You and my boss might look at all the same information and arrive at the same conclusion except how can you be sure that the path my boss took reflects your own logic and not prayer?
If the information about your world passes through a filter to determine if it fits your world view or not it’s possible to serendipitously make the logical decision but it doesn’t mean fundamentally you accept the logic of the situation at hand.
If your foundational understanding of what constitutes possibility, I.e. that when Jesus died he was transported to north America for 3 days prior to being resurrected I have trouble believing this doesn’t influence your day to day decisions.
Most people don’t actually know what logic is. I would ask him to define logic to see where he’s coming from. Because most people either don’t have a definition or if they do it’s different than the one the person they’re talking to has. But to do that, you’ll also want a definition you could explain to someone else going into asking the question.
I’ll take a swing at it. I’m curious how I’ll do if I just wing it.
Logic is a set of rules that can be used to form repeatable results based on given information. It’s often built using one’s own knowledge and experience. Logic does not require producing accurate results. Flawed logic is still logic. Logic also does not guarantee that the results are the desired results, this is sometimes described as “garbage in, garbage out”.
I’m not apathetic about religious people because unfortunately they continue to occupy positions of authority in our society.
If religious people were actually dismissed in the way you describe I could understand your perspective. They are not mocked liked this though and are very much taken seriously.

No need to pick on religious people in this case. There are plenty of people with various character flaws in positions of power / authority.

So you don’t know about:
Bill Maher
Bill Hicks
George Carlin
South Park
any comedy movie that involves a religious character
Notably those examples make absolutely no difference on how religious people in authority positions frequently use their religion to guide how they use their authority (which ain’t fucking cool)
I can use whatever word for church you want, bud, theyre all the same thing with a different title. Temple, parish, mosque, its all big rooms with a speaking spot up front
Please tell me how south park poking fun at you, as they do with everyone, affects your ability to legislate. Last i checked the jokes haven’t stopped anyone from cramming their religion down our throats
