woowoo physics

It's like watching people argue if santa's reindeer are powered with magic corn or camoflauged jetpacks...
 
I heard of perpetual motion but perpetual thermite? Then this guy does an about face and ignores the laws of thermodynamics?! Is this JTGOB Pinky or the Brain????
 
Lol, good find.

Unrelated to this thread, but related to their thread...
I still have no idea how they come up with these conclusions based on nothing.

"Molten Metal = Molten Steel"
"Black Smoke = Oxygen Starved Fire"
"White Smoke = Aluminum Oxide = Thermite"
"Iron Oxide = Thermite" (Actually Rust Lol)
"Opinion Piece = Factual Report"
"Questions = Evidence"
"Speculation = Inside Job"
"9.2 Seconds = Controlled Demolition"
"Puff of Air = Explosive"

Basically I have no idea why they are so sure molten steel was found under the towers when no one has seen any peer-reviewed scientific analysis that determines that the molten metal under the Towers was steel.

They've got nothing but speculation on this point.

These are the most physics challenged guys in the world! (there are some people trying to be correct but they risk being banned)

Dylan is running a day care forum for the mentally impaired idiots of the world.

Dylan how can you be so dumb?? (Dylan will ban anyone who is knowledgeable in physics; Why? Does Dylan know it and he wants the fiction to continue? Or is Dylan as dumb as the rest of his followers and he will bad the truth cause it appears the truth is a lie? )

Did Dylan or his team ever finish physics?

Don't forget:

Explosion = Bomb

Oh and then there's

I forget where the video is but somewhere there is a video of the big blue collapse at Miller Park. As the foot thick bolt snaps you would swear it was an explosion. I have to find that video...anybody have any idea where it is?

i heard an interesting explanation on another forum about how a fire can get hotter than its "supposed" to, and it makes sense to me

a fire is essentially a chemical reaction, and it evolves a certain amount of heat, the guy said that by preheating the reactants beofre they are combusted the fire will only get hotter

for example if you have something that burns at 1000 degrees, heat it up to 1100 degrees then add the oxygen to let it burn, its only going to get hotter, in this manner even a relatively cool "smoldering" fire could potentially produce temperatures several times hotter than the open air burning temp of the fuel

does that make sense to anyone?

Have to look at burn temp, ignition temp (flame source), and auto-ignition temp of the substance in question.

ETA
[thinking out loud]
substance X heated to temp Y. Temp Y is greater than the burning temp of substance X, but below the autoignition temp of substance X. Substance X is then ignited. Heat given off would be equal to what substance X gives off during combustion plus whatever radiant heat it gives off from its prior exposure. Yes?

well, whatever was the world trade center

but doesthe concept seem logical? that a substance can be heated past its auto ignition temp if theres no oxygen to allow it to burn? i realize at some point other chemical reactions and breakdowns will begin to occur, but i just find it hard to believe that a substance can only burn at X temp and never get any hotter under any circustances

seems kindof the same principle as being able superheat liquid water past its boiling point

I think it was JTGOB that also claimed that 2 billiard balls rolling square into each other at the same speed would stop dead. "Conservation of momentum" was mentioned. My brain was so damaged by this that I went to a pool table and started clacking balls into each other. Fortunately physics was still real .....

Preheating fuel and combustion air makes sense to many, many users of combustion for heating. It's done all the time, and on massive scale, at steel mills, foundries, forges, powerplants.. just about any process that generates heat by combustion at sufficient scale for the efficiencies gained to offset the costs of implementation. It's a good way to make use of energy that would otherwise get carried out the exhaust stack and be wasted.

Ignoring for the moment what one might mean by 'hotter than it's "supposed" to', the handwaving explanation in your second paragraph is essentially correct; every BTU (calorie, erg, foot*pound, kilowatt*fortnight, jelly-donut-unit) you add to the reactants before the combustion is still with them when the combustion liberates its contribution. That makes the total energy of the combustion products more than it would have been without the preheating. This "extra" energy of the combustion products is reflected in their temperature being higher than it would have been without preheating the reactants.
 
"Manorexia" on that thread makes an excellent case for heating through kinetic-energy. I've pretty much assumed this was the case since day one. When a fire heats up the steel to close to a thousand degrees, and you then proceed to drop half of the worlds biggest highrise on this steel, would you really expect it NOT to melt?

Actually, physics is still real, and momentum and energy conserved, if two balls rolling directly into each other at the same speed stop dead. What's missing or presumed is the elastic or inelastic nature of the collision, which depends on details of the balls and collision that are unspecified (unless one wants to apply the adjective "billiard" to imply ordinary phenolic balls at reasonable impact speeds). Lead balls would come pretty close to the dead-stop result.

What *is* (mostly) conserved in the (usual) billiard-ball collistion but *is not* conserved in the dead-stop lead-ball collision is kinetic energy, but either result is perfectly legal as long as that energy shows up somewhere after the collision. In the (ideal) billiard-ball case the collision is elastic and the total kinetic energy of the balls is the same before and after. In the dead-stop lead-ball case the collision is inelastic and the pre-collision kinetic energy of the balls is expended deforming -- that is, doing work on and thereby heating -- the balls; the energy is still there, it's just not kinetic anymore.

That said, a good excuse for a game of pool (and obligatory pitcher of beer) should always be welcome.
