The Industrial Revolution: Crash Course History of Science #21

[@nantukoprime]

Mauveine, the first synthetic dye, was a big deal because it was purple. Purple was extremely expensive before Mauveine, to the point that it was pretty much restricted to the nobility and the Church. Before, the most common suitable dye came from sea snails. That rare dye, Tyrian purple (known as the 'royal purple'), could be so concentrated from a color standpoint that the modern RGB scale used for web pages cannot accurately display it.

[@varahamihirascienceforum9149]

nantukoprime Indigo from India, before mauve, I believe. British government forced some farmers to grow indigo rather than rice, is a popular story in Indian history and the independence movement

[@nantukoprime]

VarahaMihira Science Forum : Tyrian Purple is a more reddish variety of purple, see Byzantine purple (another name for it). It's a natural composition of indigo and a red dye with similar chemical composition which is why it was so rare. There were tries of using other sources of indigo, ie the plants, combined with other red dyes. The early mixes were not strongly colorfast and would revert to the more indigo hue with age and washing (indigo itself is a difficult dye to mix until industrialized societies as it is not water-soluble). Mauveine was a strong colorfast purple that could be altered towards either red or blue tones of purple. Best of all, it was comparatively cheap. The Southern US colonies and Caribbean were forced to grow indigo as well. It was one of the main reasons for the slave trade in the southern US prior to the cotton boom.

The most expensive pigment was actually ultramarine, which could for most of human history only be created by grinding down lapus lazulus, a mineral only found in afghanistan and usually considered a gemstone.

The Industrial Revolution not only streamlined the production process through the factory system and led to the explosive growth of the middle class but also changed the way people in Europe and North America viewed science and the notion of invention. Europeans essentially "invented" the idea of the invention during the 1800s. Entrepreneurs and scientists constantly tried to invent to devices, improve the designs of machines and advance general scientific knowledge to increase profit margins and improve standards of living. In the 1800s, people also became accustomed to the idea inventions and scientific discoveries would continue to advance and improve peoples' lived in the future. Although they did not know exactly how scientific advancements would pan out over time, by 1800 the smartest westerners new technology would transform the world and make the future different and better than the past. Shortly after the American Revolution, Benjamin Franklin noted that he wished he'd been born 200 or 300 years in the future because machines, technology and scientific discoveries would have utterly transformed the world for the better. Many other European and American mathematicians, scientists, inventors and intellectuals shared this notion of a future transformed by technology for the better. This had never occurred before in history and is the paradigm shift that made the Industrial Revolution the most significant event in world history since the Neolithic Revolution and the dawn of recorded history. It is no coincidence that the 1800s is also the century that witnessed the dawn of science fiction as a genre that exemplified this newfound notion of a future made better by technology. The Romans were great engineers and actually invented the steam engine but lacked a way of thinking about the future that allowed them initiate an industrial revolution and transform the world through machines.

[@cboisvert2]

It's a shame you skipped the ancestry of the steam engine. The ancient eolipyle used steam, but was just a curiosity until scientists got to understand pressure, develop tools to handle it, which set the scene for Savery's and later engines: first Torricelli understood the role of air pressure, then Pascal tested it by climbing up mountains and church towers with a column of mercury in hand - evaluating the size of the atmosphere in the process. Von Guericke, following them, built an air pump and tested it spectacularly. Robert Boyle improved that pump to study gases, and Denis Papin, experimenting for him, got the idea of the pressure cooker. Finally, looking to something safer than gunpowder to run engines, Papin made the first piston in 1690. 8 years later the savery engine was patented. The story is interesting IMO because (1) it brings to light key people that didn't make it to your series so far (Pascal! Boyle!); (2) it shows (again) that science is not national: this story travels from Italy to France to England with power and prosperity. (3) it shows the importance of the royal society, which employed Boyle and Papin (Papin had to leave France because of his religion), and set challenges like pumping water out of mines.

[@faceoctopus4571]

I'm not so sure it's right to say they "used steam" if it was "just a curiosity:. That's probably being pedantic. And you're right, they shouldn't have skipped it!

[@cboisvert2]

@@faceoctopus4571 The aeolipile was a remarkable object, fast spinning, revealing the potential of steam, but it didn't bring it to any use - and as is it couldn't have been any use, too much water lost and too little power gained. So it remained an "curiosity" - an interesting object for the enquiring mind, but nothing more.

[@georgytodorov7947]

The HMS Dreadnaught was launched in 1906 and gave her name to the class of battleships based on her construction... that's definitely NOT the mid-1800's. Maybe you meant to say ironclads?

[@MakeMeThinkAgain]

I was wondering about that, too.

[@DaDunge]

The ironclads weren't a big step forward though, not until the monitor introduced propellers and pivotable gun turrets.

[@hedgehog3180]

Correction for 7:04 Dreadnoughts weren't a thing until the 20th century with the launch of the HMS Dreadnought in 1906. You're probably thinking of Ironclads. There were ships named HMS Dreadnought before this but none represented the same revolutionary break in naval warfare as the HMS Dreadnought did.

[@talideon]

There are a whole bunch of issues with the way you breezed over agriculture. For instance, while the old system of the commons was indeed change agricultural yields in England, it wasn't England's agricultural output that fed the UK, but Ireland's, which was purposely kept from industrialising, except for the area around Belfast. The consequences of that are also still felt to this day.

[@DaDunge]

The introduction of new world crops was also a big part of what changed the region. It's also why france which had been the most populous country in europe for centuries fell behind in this era.

[@cboisvert2]

@@DaDunge France did adopt new world crops at the time. The reason why it's population fell behind is (1) the wars and revolutions, and (2) it's population density having been high, the rest of Europe caught up more than it fell behind (in the 19th cent., not the 20th!)

[@second2none914]

He also breezes over how Britain industrialising first led Britain colonising half of Africa and all of India to get the resources needed to fuel its industrial revolution, while purposefully keeping those areas from industrialising too, similar to Ireland, the effects are still being felt to this day.

These Industrial revolution's process began in British on 18th century and from there it became spread widily to the other parts of the world. Industrial revolution made the lives of humans easier and the development growth of economy. But it sad to say, that it has negative impact in our environment. That mostly most of us didn't see and care about the negative effects in our environmentand when it comes to our mother earth. I hope we can less using factories that can destroy the mother earth.

The (American) Industrial Revolution was one of the reasons for the Civil War, in that it made slaves less necessary and the idea of slavery less "fashionable" (at least, to Northerners.) It is also one of the reasons why the North won the War. (Better technology, infrastructure, and material production.)

[@geoffreywinn4031]

Cool video!

[@ShaedeReshka]

The industrial revolution is a surprisingly controversial subject and there's some antiquated information in here. For one, prosperity wasn't exactly what prompted the industrial revolution, unless you really want to describe colonialism, slavery, and domestic servitude as prosperity. These things led to the economic conditions that would allow industrialization, but conditions worsened for the majority of the population while "prosperity" only really occurred for the rich industrialists. The "free market" was the transition of mercantilism into capitalism through liberalism, but that's another subject. The "population boom" is another controversial topic. Insane asylums were emptied out to make room for new laborers (being unemployed was considered a form of insanity before the industrial revolution) and the witch hunts resulted in robbing most people access to birth control. Also... slavery, colonialism, and servitude. The process of enclosure actually resulted in a period of starvation as yields fell. The impoverished, robbed of the common land they used to work and gather in, were more dependent on the market for survival. To make up for this fall in productivity and keep the population from starving, countries turned to... you guessed it... colonialism, slavery, and servitude. That's kind of the theme here. With that out of the way, the rest of the episode was an excellent overview. This being my field of interest / study I couldn't resist providing another narrative for the brave comment readers of this video.

[@blasterjosh]

Not to mention Great Britain was in a really strong economic spot to dominate the world trade thanks to the napoleonic wars destroying europe

I prefer courses on Science be about Science. Trains ‘caused’ divisions between social classes was in the intro. Maybe for a sociopolitical topic, but not science. I usually love love love Crash Course, vlogbrothers. But it’s sadly trending, like many things, into political opinion pieces.

[@ShaedeReshka]

Meehleib Science is political. Everything is political. That's just how it goes. Pretending it isn't political is political.

[@qbslug]

Metadigital+ " but conditions worsened for the majority of the population while "prosperity" only really occurred for the rich industrialists. " Just because some people become very wealthy doesn't mean everyone becomes poor. Its not a zero sum game. Wealth that didn't exist before can be produced through advancements in technology. There is no doubt that the industrial revolution increased the standards of living - the only debatable part is how long it took to take effect. "The "population boom" is another controversial topic" Not controversial at all. Just look at trends in world population and the spread of the industrial revolution. The effect again wasn't immediate but there is no doubt the industrial revolution made significant population increase possible.

Yup. They also have consequences. For instance, the Great Smog of London (which killed about 10,000 people and injured hundreds of thousands more), acid rain, and mercury bioaccumulation in fish can all be traced back to our coal- and petroleum-burning habits.

Hello team CrashCourse, I am a keen viewer of your videos and find them very interesting and full of knowledge but I want to say (complain about) two things :- 1. Why do you speak so fast? Not everyone among your audience is from a English speaking nation. Consider foreigners as well. Sometimes it's very difficult to understand what the host speaks. And 2. You don't give enough time to read the cards/messages that pop up during the video. Please give appropriate time for that. I hope you will consider this sincere request. Thank You. A fan from India.

I am very glad you made this, and I was excited to see another episode, but I am disappointed that you ignored all the prior knowledge of Steam Power that was developed, and in some cases put to use, by the Ancient Greeks. Somewhere in the world beyond Ctesibius, Heron, and Archimedes are crying.

[@varana]

There was no follow-up to those, though. (And the stories about Archimedes are at least doubtful.)

[@MasterOfCydonia]

varana312 Though it is true there was no direct follow up, there was indirect follow up by medieval scientists trying to understand how the ancient peoples did it, only to then be developed upon further in the Renaissance, then again in the age of enlightenment, and only to be mastered by the industrial revolution. My comment was only to point out that Crash Course left out some of the most important progenitors of the idea of Steam Power to begin with.
