It's supposed to represent mexico...? The US flag is described as red white and blue in the US...

I hope this made sense as without a reference to pictures or physical objects it's not easily explained in an understandable manner. I learned much of this throgh youtube/internet as for me i have to learn through example and seeing something done. I also hope i answered your initial question... i tend to ramble on at times

Now this is where tempering comes in as the metal is reheated, tempering very rarely reaches the point of almost melting, to a temperature lower than the melting point and air cooled. This lack of sudden cooling allows the crystaline structure to move about more freely which in turn lessens the hardness of the material.

Now after the initial cooling and crystalization often times defects/gaps are formed between crystal structures. To remove these defects the metal is then heated to the point of nearly melting and cooled almost instantly. This freezes all the atoms/crystaline structures that filled these gaps in place. This is the point in which the metal is hardest and most brittle. This occurs because there is no gaps and no room for the crystaline structure to move about. Meaning that if brunt force were to be used the metal would break as there is no where for the metal to give.

As all things do metals have a metling point, at which point the metal is a liquid. As the metal begins to cool a crystaline structure is formed. Within this crystaline structure each individual crystal has it's own grain. Each grain acts independently of eachother.

Okay, now that I'm on break i can elaborate more on how i understood it from school. This will probably be multipart as it's actually really complex and for me to explain it all requires me to start from the beginning.
Basically at the atomic level all atoms for very tight bonds with the other atoms surrounding them. Now what differs from other atomic structures is that the electrons in the outer layers of the electron fields (valence electrons) aren't tied to one specific atom but to all atoms. In essence all the valence electrons move about freely within the metal.

Well technically tempering makes steel less hard... tempering occurs after the hardening process to remove excess hardness. As far as i understand it reduces the stress on the steel. I'm not near as adept on carbon steel as i am on stainless steels so I may be off...

Honestly... if someones interested pewdiepie actually does a pretty good explanation of the whole situation. (Although he is comedic about it throughout it's fairly unbiased) He comes at it from an angle, one from within the industry, and has different insight into the whole ordeal compared to the current accepted narrative people seem to be hounding over.

I misunderstood what this was about. I thought with the alabama thing this was referencing abortion and not female birth control. My bad.

And if you declare war on them because of it then you get a warmongering penalty. Like wtf am I meant to do?

I'm not sure why I've been downvoted for stating the argument. That being said I don't understand this big hatred for unions in the US. Some unions are counter-productive but many aren't.

In most companies the union and non-union workers receive the same benefit as the union negotiates for all employees and not just union ones.

Canada and the us are the only two, major, currency's to have bills be the exact same size accross all denominations.
