making a fool out of myself

[Holden Caulfield]

but how does gauze keep flames behind it when it has holes in?:confused:

[Rosa Lichtenstein]

HC, can you re-phrase that in a Western European language please? :confused:

[ÑóẊîöʼn]

I understand the question, but don't know the answer.

Rosa, I think he is talking about THIS (http://www.flickr.com/photos/[email protected]/1495100891/in/set-72157602272495872/).

I am fully aware that when I post in a way that represent the way I speak in my day to day business I may be hard to dispher, however your complete inability to understand what I am saying is strange, strange indeed.



I understand the question, but don't know the answer.

If the science guys don't know then I am doomed to a life of bitter ignorance, this true is witchcraft

[Post-Something]

Yeah, I always wondered about that...

[Raúl Duke]

wow...I didn't know anything about this gauze and flame thing till now.

The little holes in the gauze act to dissipate the heat of the flame fast enough so the that the gas on the other side of the gauze doesn't ignite. The technique was pioneered by some guy ( i dont remember his name) in an attempt to create safer lamps for miners; since those things had a tendency to explode.

This is the one thing i learned from chemistry class.

BUT HOW

i want some kind of diagram with annotations and arrows

Im afraid i don't know of any diagrams explaining this phenomenon, but if i remember correctly; its because the gauze conducts the heat from the flame, and spreads the heat around the entire gauze, rather than simply permeating through the holes. Unfortunately, I don't know of any formulaic explanation of it.

Most metals have a "sea" of free electrons called the conduction band, more loosely attached to the atoms than the electrons in the valence band are. Any thermal vibration at all, the fact that the temperature of the metal is something above absolute zero, is enough to kick the electrons loose from the atoms. The electrons don't belong to particular atoms. They can bond to atoms only loosely and for a very short time, and then they keep moving, which is sometimes compared to the "musical chairs" party game. The free electrons make metals the best conductors of electricity and also the best conductors of heat. The atomic lattice itself also helps to conduct heat because the covalent bonds behave like "springs", they are elastic. The speed of the flow of heat in any solid is approximately the same as the speed of sound in the solid.

That's really cool to know. Where did you learn this?

How the hell couldn't you understand that, it's pretty self explanatory.

[Yazman]

To be fair, the question is worded in a very bizarre way and I didn't get it either until I saw pics.

[revolution inaction]

I don't think it was bizarre, it made perfect sense to me.

@ NoXion he probable learnt it in physics or chemistry, i thought everyone did, but it might not have been till a-level

Well, perhaps you are fluent in Klingon, but I am not.

[mikelepore]

Where did you learn this?

I have an MS degree in electrical engineering from the U. of Vermont and I worked as a semiconductor chip designer for 18 years. The facts that I typed are like the basic ABC's in the field -- there isn't anyone who doesn't know them.

[Holden Caulfield]

i find that offensive, everybody else can understand me when i type things colloquially

But he said it in basic English.

By the way, is it not ironic you'd talk about things being hard to understand when you have made a whole website full of useless jargon which no one but yourself and possibly Jacob Richter could possibly ever understand?

This is not the place for personal attacks, I suggest you keep ad hominem out of your posts in this forum. Keep that crap in chit chat. Not to mention you are mistaken in your analogy as the website you are describing can be hard for some to understand due to their inability to grasp the concept, rather than just being hard to understand because its poorly worded (like the question in this topic).

:lol::lol::lol::lol::lol: That's the funniest post i have read on this site... ever

Apologies HC, but I find you in general difficult to understand.

Like what, for example?

Its okay, its hard to talk to the plebs they have the most horrific lexicon.

[Rosa Lichtenstein]

I am a 'pleb', but I still find it hard to comprehend what you say.
