One correction: As far as swords, knives, etc. are concerned, modern steels are FAR superior to Damascus steel. The particular process might be lost, but the end product, although pretty, would be demolished by a modern reproduction. And anyone can buy a reproduction sword online today from numerous makers, including some superb ones for under US$1,000, that are more durable and effective than any sword owned by any medieval king.

Similar correction: Roman concrete isn't superior to modern recipes. A lot of modern concrete contains rebar (steel bars or grids) that help give it tensile strength. Roman concrete did not have this, and as such wasn't that great under tension. The upside is that Roman concrete lasts longer. The steel in reinforced concrete expands and contracts thermally, causing gradual cracking and weakening of the concrete around it. Over decades, it will break down. Because Roman concrete doesn't have rebar, it will last a lot longer. But so will a lot of non-reinforced modern concrete.

That bugged me too. The Romans, for instance, were _experts_ at torturing humans. The use of crucifixion with the T-shaped crossbeam on an upright pole was pure torture and they knew exactly how to make it incredibly painful for a really long time. It's said that some crucified men would hang up there for many days ... putting the nail through the lower part of the hand where it meets the wrist would put it right through the sciatic nerve, causing a shooting fiery pain, plus the radius and ulna would keep the spike from ripping out ... there's much more to it than that, but I'm getting depressed typing it out. He might be referring to torture as a form of getting information, but it still doesn't seem correct that it "started" with the Catholic Church in the 1300s.

The thing you didn’t mention about torture is how bad it is for getting reliable information. If you torture someone, they’ll most likely tell you what they think you want to hear to make the torture stop, regardless of whether it’s true. A person who doesn’t know an answer will make one up. The best interrogators form a rapport with their target and have conversations where they’re able to pick out valuable information that’s let out, sometimes unwittingly.

That depends on what information you're after. Yes, the victim will tell you whatever they think will make the pain stop - but that includes the truth, so the issue is whether you can identify the truth when you hear it. Torture is utterly useless for questions like 'Did you do it?' or 'Who were your co-conspirators?', but questions like 'Where is the bomb?' can - not _should,_ just can - be effectively answered by torture.

To further expand on "slash and burn farming," you also need "crop rotation." Today, farmers do field burns, but the thing to pay attention to is how they nearly always plant something different on that field next season, and so on. Planting the same thing on that field only depletes the nutrients in the soil, making it as useful as concrete. Every second or third year, you need to plant something which ADDS nutrients to the soil. On a smaller scale, you can see the same phenomenon in your home garden. Every year, you need to rotate the garden. Every second or third plot needs to be some type of bean or pea, so when you rotate the garden every year, that plot now has something which fertilizes the ground. You fail to do that, and the ground will be as useful as concrete. In conclusion, the simple fact of burning fields is not what makes the fields useless. What makes the fields useless is nutrient depletion, caused by planting the same crop on the same field every year.

Chemical fertilisers damage soil microbes, so are not good, despite the video's claims, but what is in them gives a good idea of what crops need, they are generally called "NPK" fertilisers, Nitrogen, Phosphorous, Potassium. Nitrogen will actually suppress the growth of any plants other than leafy greens, causing the plant to produce only the leaves, not the fruit/seed/tubers. Legumes do NOT add potassium or phosphorous to soil. Ash adds potassium (pot ash), phosphorous can be added with animal manure or chemicals

As a note, Damascus steel was not "superior to modern attempts." It was a lot better compared to most other contemporary steel alloys, but many modern ones are still better. Modern metallurgy is damn impressive, and Damascus has even been recreated artificially at this point, where the original could be considered partially down to the luck of happening to mine in the right spot. At least where the iconic look was concerned. Also your shot was a pattern-welded blade, not true Damascus, but that's another matter.

A word on lead, and chemistry in general. All chemistry relies mostly on its valence band of electrons. That's the outer most orbital. That's why everyday table salt, sodium chloride (NaCl), is relatively harmless, and actually needed, in modest amounts. Yet pure sodium metal is extremely reactive, reacts violently, when exposed to water, and chlorine (chloride) in pure form is a poisonous gas. That's all due to the way they are bonded; the valence. Pure lead metal is quite benign. So are mercury, and even gold. Yet, all three of these metals when reacted with other elements, such as lead sulfides, they become toxic. Lead is mostly non-reactive, but will react when exposed to acids, such as those in wine. Holding lead solder in your teeth is way less dangerous than inhaling flakes of old lead based paint, as in the paint, its a lead oxide. Gold is usually considered safe, because it barely reacts with anything. But if you do, its extremely toxic.

I'm glad I didn't become a big fan of fishing, because my grandfather taught me how to put lead weights on my fishing line by using his teeth to spread open or clamp down a weight instead of using needle nose pliers. I think I might have done that perhaps five or six times during my childhood, at the most. But I do remember that it always left a distinct metallic sweet aftertaste in my mouth. I get it about pure lead, but I believe I read somewhere that even a pure meta has a patina layer of oxidized lead wherever it gets exposed to oxygen. I may have that wrong, but I believe things like lead fishing weights or lead drinking cups will have a film of oxidized lead on them.

The best option is actually livestock. That is in fact the ONLY option that's been found to work on mine tailings or volcanic rocks, where the soil has been turned into just dirt & rock, with no living microbes left. In those settings, manure is the best option, as it is full of the microbes the soil needs, but by depositing it via the livestock, rather than via truck, it means the livestock trample it into the existing soil as well & stir everything up, so as to bring it back to life, particularly when the liquid from the urine is added into the mix. If you were to dump the orange peels onto the land, add some hay & then bring in some cattle to eat all of that, it would take only 1-2 weeks before the soil would be restored. The orange peel alone will take a minimum of 3 months before it reaches that same point reached within 1 week if cattle are allowed to process the peel via their rumen microbes

Just a quick correction. in the intro the example of "Damascus steel" you showed is not actually Damascus steel, it's welded steel. True Damascus steel was crucible steel (high carbon) with most impurities removed. This steel is roughly equivalent to what industrial steel is like today in modern times but without the precision smelting of modern tech. Welded steel can be sturdy to a point but the bigger the piece the more likely it is to contain air pockets which make it brittle and due to the welding, layering, and grains is arguably less effective than high carbon steel which is far more flexible (as far as I am aware), with spring temper being arguably the best steel for weapons and possibly armor. For further clarification, Damascus steel got it's name from where Nordic traders often picked it up from: Damascus, Syria (formerly Persia).

I have heard that the Roman lead pipe problem wasn't really all that significant; that the water flowed through them fast enough that very little lead leached out into the water. Lead containers may have been more problematic. But I think that lead doesn't absorb particularly well through the digestive tract, so most of the lead that's ingested ends up getting excreted. I'll note as well that we continue to use lead today in things like lead crystal glasses and containers. Plus most faucets use lead in the seal that stops them from leaking. That lead does leach out into the water that sits still behind it for hours and hours, so you'd be well advised to always run the faucet for a few seconds to let that contaminated water clear before filling your glass with it. A far more significant source of mass lead poisoning has been leaded gasoline, since lead is absorbed quite easily through our lungs. And unlike the Romans, who just didn't know any better, we were fully aware of how toxic it was when we adopted it.

The first part about Roman plumbing is a urban myth : lead is extremely toxic but it has to come inside the body before. Natural water is generally basic or alcaline there are localized exceptions). When in contact with lead, this alcaline natural water produces a thin layer of alcaline salts on the surface of the lead in a few seconds? This layer prevents all lead or lead composites to go into the water. That is why the first thing to be forbiden in the modern world were lead paints, lead gas and lead beauty produces, not lead pipes which are still is in use in many old buidings all across Europe and America. As for the culinry tools : lead is not a good metal to use. Most of the roman culinary tools were clay, bronze, iron or steel.

So, if someone says to you "you have to change your lead pipes to PVC ones", say no : they just want your money and you will not be poisonned (except at the end of your life if you live more than 500 years...).

why on earth did they leave it in the sun for days & then burn it? That makes no sense whatsoever! How it is done in Australia is the cane is burnt to remove snakes & other dangers (& in days past, to remove the spiky bits that are like cactus on the cane leaves that are a problem for hand harvesting), then once the pests are cleared, the cane is harvested, with raillines built through all the farms, so that the cane can be IMMEDIATELY loaded & transferred to the factory for processing, because even 1 hour between cutting & processing results in a 50% loss of productivity/sugar that can be harvested. After processing via chopping & squeezing to extract the juice, the waste is used to power the processing factory, plus returned to the cane fields or other places as mulch, with nutrients from the mulch leaching over time into the land it's placed on

@@mehere8038 That is more or less how it has been done in the past here, but now the little rail lines, which we used to call "dummy-lines", are handled by tractor, hauling a trailer, sometimes two of them in tandem. The cut cane would only be left for a couple of days, so that the leaves would wilt, and burn better. The sugar levels would remain the same, even though the moisture content was diminished a little bit. After squeezing, the left over cane used to be called "bagasse", and used for making insulation, ceiling tiles, and various construction products. A lot of it was also used to to run the boilers in the sugar factory here, too. I don't know if they are still allowed to do that, but they used to.

​@@feldgeist2637 um, you don't understand what sugarcane burning is about lol. I grow sugarcane in my garden, I know how it works! You do NOT want sugarcane to dry out! The liquid in sugarcane is the sugar! Any drying means sugar losses! Sugarcane is traditionally burnt while in the ground growing. The process was discovered in an industrial action, where workers objecting to working conditions set fire to the fields to destroy them & result in the landowners losing everything. Result was unexpected, the sugar was just fine, just the snakes & spikes were removed, improving conditions while leaving the cane fine. The fires remove the dead, dried leaves, leaving the growing stems protected by their thick skins & sugar inside untouched, but all the rubbish that was making them hard to harvest gone. Today, fires are still used in much of the world, particularly where hand harvesting occurs, but also in some machine harvesting cases, cause removing the dried stems makes cutting the living ones easier & allowed higher density crop planting & harvesting. Fire reduces the quality of the cane though, so for this reason it is undesired. In years gone by though, people really didn't care that the sugar wasn't pure white, the ash content in it didn't reduce it's value in the way it does today. Drying to burn occurs later in sugarcane, the "drying" is done via extracting all liquid from the cane, leaving only very slightly damp bio-mass, that can be fed into electricity generators to power the operation. When I harvest my cane at home, it's super heavy, moist blocks, that I then press, resulting in about 1-2 litres of liquid (sugarcane juice) per stem & fibre waste that is very light weight & touch dry. I know if I have fully extracted the sugar or not, because if I did, when that waste is placed on my garden as mulch, it will act the same way as commercially bought sugarcane mulch. If on the other hand I was lazy with my pressing & moisture remains, it will mould up with rain, even though it appears fairly dry initially. It will also be heavier, due to the remaining liquid. I use a hydrollic press that is basically a car jack, capable of lifting or applying over 1 tonne of weight to crush the cane, in an area of a 10cm circle

​@@otpyrcralphpierre1742 your info makes no sense whatsoever. Why would they want to burn it after the sugar had dried out? What good would that possibly do anyone? From Australia's sugar research site, disadvantages of burning cane before harvest - Harvest must be completed within 24 hours to avoid deterioration. Under hot and humid conditions, significant deterioration can occur within 10 hours, and within 16 to 20 hours if conditions are cool and dry. - Removes a valuable source of organic matter for the soil. There is also extensive discussion about the reduced quality of the cane produced from burning, due to increased ash & discolouration, so why on earth would it be burnt AFTER harvest, when there is zero benefit to that but huge disadvantages & yield reduction????? & no, sugar levels do NOT remain the same at all, I will post the details on that separately, as I seem to have removal issues when I talk about burning related stuff for some reason

@@mvalthegamer2450 true in some cases, or maybe in all as humans figured out where they fitted into ecosystems. In reality though, in cases like Australia, they can't even figure out for sure when megafauna went extinct, cause there's evidence that contradicts itself & when the last large predator went extinct, which usually results in a complete ecosystem failure, in Australia, there was no such thing, because humans were embedded in the ecosystem as the apex predator & keystone species, keeping everything completely stable. When white ones arrived, things totally changed & kangaroos started to go into "boom and bust" periods with overpopulation & then mass die offs, but all evidence says they were totally stable in population for millennia before that. Dingo introductions & Tasmanian tiger die offs on the mainland that accompanied it 5,000 years ago being the only really clear change to the ecosystem after the changes that occurred to the plants 120,000 years ago & the impacts of the 15,000 year long iceage mega drought. Not all human communities were causing destruction, a lot were living in harmony with the ecosystem, as a part of it - and not just in Australia

It was a lot harder to convict the actual criminals, which is one reason why capital punishment was preferred punishment in earlier times. Of course, there were also a lot more wrongful convictions. However, since the likelihood that you would be tried and convicted of the actual crime you committed was lower, the punishment needed to be graver to act as an actual deterrent.

Sure, it was sexist and wrong, but it wasn't put in place to benefit women. It was put in place to protect men from being cuckolded while still allowing them to keep their wives for having children.

As far as burning is concerned, it's important to understand when a burn is good for the land and when it's not. Burning is a natural and very important part of the ecosystem. It essentially resets the land, repelling overgrowth, disease, and releases long trapped nutrients back into the soil. Burning is not however a quick fix to infertility. burned soil needs time to redevelop its biome and microbiome before being used for large scale production. A good burn strategy would be to burn on rotation, only burning small patches at a time and letting the land rest for an extended period before growing on it. The problem with slash and burn farming isn't the burning itself but the attempt to rush the life cycle of the soil.
