Besides just being interesting in and of itself, I think it raises an important caution for laypeople. It’s easy to read a secondary source and take it as authoritative, while having no idea where that source falls in the wider conversation. Consider how high school students are taught very different things about the civil war depending on what state they happen to grow up in (not trying to raise a shitstorm, it’s an example). It’s hard to evaluate anything you read when you don’t know what you don’t know.

His writing falls a little bit more on the academic side but is still entertaining and easy to follow (although quite some time is required ;) ).
What I like in particular is that he mentions when we simply don't know things and why we don't know them(e.g. because some materials don't last that long).
There was also another technique called spiral welding in use in the Middle East and Central Asia that apparently worked pretty well. IIRC when the British captures the Bengali cannons after the battle of Plassey they were very impressed by the tubes if not the carriages. They ended up spiking them because the bore widths weren't standardized but they could fire further than the English cannons.
Just like software engineering
If you're reading this Bret, that is some terrific research and writing! Thank you!
The "journey" part of journeymen is because they would usually travel around instead of waiting for space in the local guild. Compare the (nominally white collar) postdoc.
(I still see wandering journeymen, in traditional garb, from time to time.)
(I learned about Mons Meg from the Corries' interpretation of Bonny Dundee, https://news.ycombinator.com/item?id=24617941 , a tune which deserves an electro or metal cover, but doesn't yet seem to have any.)
Stop, hammer time!
Go with the flux. It is said
If you can't weld with it
Then you probably are dead.

Hail the blast furnace!
But even today, about 8% of global iron production is by direct reduction. As coal use is phased out, this will rise, and eventually all iron will again be produced without blast furnaces, possibly using "green" hydrogen as the reducing agent.
It's very much in his interest to have a crappy first draft hit the front page here and fix it up after that.
Probably the best way to view is searching the headline though, it's some brazen content thievery, some even copy comments like our own in there.
Absolutely hilariously how people found my original comment so offensive as to gray it out, was simply repeating something anyone can find in 3 seconds on Google.
