    A year ago, I found myself completely unsatisfied with my career. I felt like I wasn't improving anything in a meaningful way.
    Thanks to this channel, and others that focus on STEM, I got up the courage to go back to school for another degree...in material science!
    I absolutely love everything about materials, how they're made, how we can improve, and how they're used. Thank you so much for inspiring me to follow my passion!!!

      +Chunk'o What
      I see what you mean but disagree. Primitive Technology is a different kind of channel with little to no comparison to Real Engineering. Also, saying "best channel on youtube" was just a way of saying "my favorite channel" or as others might say, "best channel eveeerrrrr!!!".

I wanted to mention that you personally have inspired me to go and follow what I like to do which by chance is materials engineering. Thank you so much and thank you tom for inspiring you.

    Just a reminder that the important people from that “Awe Me” (man at arms reforged) channel, split off and made an amazing new channel called “That Works,” and I HIGHLY recommend going there instead of Awe Me.
    Also mad props Brian. I’ve joined your channel late about 5-ish years ago, but haven’t seen the much earlier videos. Your continued tribute to your good friend is just amazing. You are absolutely a critical resource to everyone. Your videos are not only entertaining, but a gateway-drug for kids to get into STEM. My niece and nephew are already hooked. You, and the inspiration you took from your friend, are absolutely invaluable to the world. You continue to gift us with knowledge and inspiration, so I truly truly thank you for taking the time and effort to make these wonderful videos.

    Your pronunciation of "Spiegeleisen" was actually pretty good. Only difference is that "sp" and "st" in German is pronounced like "shp" or "sht" - unless you're from Hannover, then you said it perfectly right :)

    • @Mattipedersen

      Steel: One part iron, two parts coal (which is somehow more difficult to come by than the iron itself)

      That's why I said he shouldn't call it the perfect blade. Exactly because rating swords shouldn't be something done on an engineering channel, especially when the rating is done by some almost mystical properties (those exact wee-a-boo fantasies), that aren't based on reality.

      ​@@WearyKirin True; however, peasants don't have chain mail or iron plates. Or armour of any kind, for that matter.
      Please forgive the following mini-rant, and please correct me if there's an error:
      The idea of the Katana as the "Ultimate Sword" is absurdly romanticised, and probably comes from a combination of the sword being the self-defence weapon of choice of the Samurai class, the use of swords by officers in militaries the world over, and the longstanding influence of Bushido on Japanese culture. However, saying a Katana can't penetrate armour is a bit like saying a 19th century flintlock pistol can't shoot through a tank: neither was ever used for that purpose. Tough it did evolve from weapons that would have been used on the battlefield, the modern Katana is a weapon used primarily for either self-defence or duelling, and in neither case would an opponent be wearing armour.
      Also, let's not forget that in almost every respect, the spear is the far superior battlefield weapon: it has longer range, takes less metal to make, is easier to use in formation, and requires less training.

    Hey mate. If your going to talk about katanas... err... yeah... From someone who loves swords let me just say this. They are not the perfect sword. Nor is most swords. They are highly exaggerated in their performance but that does not mean they are bad. European swords are just as good. Its more to do with the quality of the blacksmith making the sword, not the type of sword.

    While this is a neatly painted picture. It's oversimplified. No mention of pig iron, what exactly a producer gas is and the role of coke. No mention of carburized steel and case hardening. Or the superiority of bronze in most cases as a material over ductile irons. No mention of monel or stainless/super steels (natural or other wise) which if one is going to talk about meteoric iron is very important. I really feel like there is just too much lost in the condensing of the information to call this accurate.
    I mean it's well made for what it is (the production value is there). It's one of the better attempts to reduce the subject down to it's basics that I've seen. But there are just too many points where a felt compelled to figuratively raise a finger to something said. It's really not a subject that can be treated fairly by fitting it into such a short one off video.

    • @RealEngineering
      @RealEngineering  7 лет назад +43

      I left pig iron out on purpose, it's no different from cast iron. Having more than one name for the same thing just over complicates things. My videos are rarely one-offs, I will make a video so I can talk about a subject in more detail in future. I will be referencing back to old videos more and more in future. I'll be covering steel with more detail very soon.

    • @The1Helleri
      @The1Helleri 7 лет назад +9

      Pig iron and cast iron are not the same thing. It has much higher carbon and silicon content by weight then is tolerable in most finished cast iron products (though similar to some). It also has a lot more impurities in higher amounts than cast iron. Like manganese, phosphorous, and sulfur. And the distribution of material in pig iron is far less homogeneous, having large chunks of graphite, slag , and being very aerated. It's an intermediate furnace product. And it's formulation and even phase is highly inconsistent. If poured into piglets it will later be worked into ductile/wrought iron. If kept molten it goes directly towards conversion into steel. Or it's impurities are mostly removed and it is slightly decarburized in order to make it into cast iron products. But pig iron itself isn't very useful except as one material that can be taken any number of directions.

    • @RealEngineering
      @RealEngineering  7 лет назад +12

      Okay, you got me there, but they are similar enough to ignore those differences for the sake of clarity.

    • @The1Helleri
      @The1Helleri 7 лет назад +1

      That wouldn't be for the sake of clarity; But for the sake of simplicity. You did a great job at condensing what could be condensed. It's one of the better attempts to simplify the subject that I have seen. It's just (unfortunately) not a subject that takes well to compression.
      One could easily spend an hour or so leading up to actually talking about iron just in establishing context (what proceeded it, what enabled the rise of iron, why the shift occurred). Being clear is not always possible to do whilst keeping things simple.
      It can't be dropped onto a sliding scale and remain accurate. If it were to be accurately depicted. You'd have to go for tree branch organization. And you would end up with a few trunks and some branches that intertwine and loop back on themselves.

      No offense, but every single "fact" you guys have parroted here is either complete myth or misconception that has been thoroughly debunked time and time again. It's literally just as wildly inaccurate as claiming the katana could cut machine gun barrels in half.
      I highly recommend all of you go over to Shadiversity's channel, and watch the entirety of his video series on the Katana. That's the best source I know of that has formatted it all into one tidy and easily-consumed package.
