Keywords

💡Scientific Revolution

The Scientific Revolution refers to a fundamental shift in scientific methodology that occurred during the early modern period, marking a departure from previous reliance on ancient Greek and Roman authorities like Aristotle, Ptolemy, and Galen. In the video, it is described as a paradigm shift that took place over a couple of hundred years, leading to significant advancements in various fields including astronomy, physics, and biology. The script mentions how this revolution challenged the geocentric model of the universe and paved the way for the heliocentric model proposed by Copernicus.

💡Heliocentric Model

The heliocentric model is a description of the solar system where the Sun is at the center and the Earth and other planets revolve around it. This model was a cornerstone of the Scientific Revolution and was proposed by Nicolaus Copernicus as an alternative to the then-prevailing geocentric model. The video highlights how Copernicus's model, despite its initial flaws, was eventually accepted due to the overwhelming evidence supporting it, such as Galileo's observations of Jupiter's moons.

💡Geocentric Model

The geocentric model posits that the Earth is at the center of the universe and all celestial bodies, including the Sun, revolve around it. This was the widely accepted model in ancient times and is mentioned in the video as being debunked by the heliocentric model. The script discusses how this model was defended by the Church, which had vested interests in maintaining the Earth's centrality in the universe.

💡Galileo Galilei

Galileo Galilei was a key figure in the Scientific Revolution, known for his contributions to astronomy and physics. The video script mentions Galileo's discovery of Jupiter's moons and his observations of the phases of Venus, which provided crucial evidence for the heliocentric model. Despite his groundbreaking work, Galileo faced opposition from the Church and was sentenced to house arrest for his views.

💡Nicolaus Copernicus

Nicolaus Copernicus was a Renaissance-era astronomer who is best known for his heliocentric model of the solar system. As the video explains, Copernicus's work laid the groundwork for the Scientific Revolution by challenging the established geocentric model. His book, 'On the Revolutions of the Heavenly Spheres,' published in 1543, was a significant milestone in the shift towards a more accurate understanding of the cosmos.

💡Enlightenment

The Enlightenment was an intellectual and philosophical movement that occurred during the 17th and 18th centuries, following the Scientific Revolution. The video script distinguishes the Enlightenment from the Scientific Revolution by highlighting that while the latter was a shift in scientific methodology, the former was more focused on philosophical and religious thought. The Enlightenment promoted reason, individualism, and skepticism of traditional authority, which was in line with the questioning of established knowledge during the Scientific Revolution.

💡Royal Society

The Royal Society is a prestigious scientific institution founded in 1660, which played a significant role in the advancement of scientific knowledge during and after the Scientific Revolution. The video mentions the Royal Society's motto, 'nullius in verba,' which encapsulates the spirit of the Scientific Revolution by advocating for empirical evidence and skepticism of authority. This motto reflects the society's commitment to questioning and improving upon past teachings.

💡Anatomy

Anatomy is the study of the structure of living organisms, and it was a field that saw significant advancements during the Scientific Revolution. The video script points out that the study of human anatomy expanded beyond the teachings of Galen, who had not dissected a human body. This shift in understanding human anatomy is an example of how the Scientific Revolution led to a more accurate and empirically grounded knowledge of the human body.

💡Giordano Bruno

Giordano Bruno was a philosopher and astronomer whose ideas about the universe and its infinite nature were ahead of his time. The video script recounts how Bruno argued that other stars could have their own planets, possibly with life forms, challenging the notion of humanity's centrality in the universe. His ideas were considered heretical by the Church, leading to his execution. Bruno's story illustrates the resistance to new scientific ideas during the period of the Scientific Revolution.

💡Paradigm Shift

A paradigm shift refers to a fundamental change in approach or underlying assumptions within a field of study. In the context of the video, the Scientific Revolution is described as a paradigm shift in how science was conducted, moving away from reliance on ancient authorities to a more empirical and evidence-based approach. This shift allowed for the questioning and eventual replacement of outdated theories with new, more accurate ones, as exemplified by the transition from the geocentric to the heliocentric model.

Transcripts

Science, it’s how we know our place in the universe, how we know what natural phenomena

are, how we know what this thing was, how we know how to not die at the ripe old age

of 36, and how we know how to write complex mathematical equations to determine how a

ball rolls down a hill.

Because of science, we were able to go from this to this, which is honestly a pretty good

thing.

In fact, those two images were only 500 years apart, so what happened about 500 years ago

that changed the course of our modern world?

By the way, this video is part of a huge collaboration between a bunch of history YouTube channels,

called Project Revolution, hence the intro.

Now, most of these people (whose videos you should check out once you’re done with this

one) are covering revolutions that birthed new nations and changed other nations forever,

and while that is totally my thing, I decided I‘d cover a slightly different kind of revolution.

The scientific revolution obviously didn‘t topple any regimes (at least on its own) nor

was it necessarily one single event, but a whole paradigm shift taking place over a couple

hundred years, granted only intellectuals really knew it would even have been happening

at the time, but it is still consequential!

Before the Scientific Revolution, most scientific knowledge in the ancient world (at least in

Europe) was based on the teachings of various Greek and Roman scientists and philosophers,

like Aristotle, Ptolemy and Galen, who all had one thing in common: they were kind of

wrong about everything.

Granted, everything they said seemed plausible at the time (and was probably the best they

could have done), but by the middle of the second millennium AD, it was starting to become

clear that they weren‘t necessarily right about what they taught.

Back then, the scientific method was a long way from being invented, so basically everything

that made sense was good enough.

Of course, the most well-known instance of this is with Ptolemy‘s geocentric model

of the solar system, which described the Earth as one single, giant, stationary sphere in

the middle of the universe, of which everything else orbited.

The other planets, the Sun, all the stars, everything.

This model of the heavens was basically the general model throughout the ancient world,

and was actually debunked by many different scientists, but the only one of them people

actually seemed to listen to was Nicolaus Copernicus, and his heliocentric model of

the solar system.

You know, for being… right.

Well, it was actually full of tiny flaws that made the calculations infeasible, but nothing

that couldn’t be fixed up by later scientists.

That’s kind of the basis of science after all, measuring Data and improving on work

done by others.

Copernicus, and many other astronomers at the time made many revolutionary discoveries

in the field, and were all rewarded for their contributions to human civilization by…

being arrested for heresy.

The church (Catholic and Protestant) didn‘t like the idea of Earth not being the center

of everything, because I mean, if they were wrong about their place in the Universe, what

else could they be wrong about?

Galileo was sentenced to house arrest, and Copernicus actually got away with it, but

only by dying just after his book, On the Revolutions of the Heavenly Spheres, was published

in 1543.

Giordano Bruno of course also argued that the other stars in the sky were no different

from our Sun (relatively speaking) and could thus have their own planets, possibly even

with their own life forms.

So, arguing that this would mean that humanity wasn’t the pinnacle of creation, the church

of course burned him at the stake.

So, if these early astronomers had such a hard time convincing their peers of this new

model, what eventually changed?

Basically, overwhelming evidence.

After Copernicus published his book, other physicists and astronomers discovered more

arguments in favor of the heliocentric model.

For one, Galileo discovered that Jupiter had at least four different moons of its own (at

least four), which orbited it, without a care in the universe for whether or not Earth existed.

The phases of Venus were also discovered to have had nothing to do with the Earth, but

everything to do with the Sun.

Eventually, opposition to the heliocentric model started to fade, with heliocentric works

finally starting to be unbanned in the church by 1758, as its influence also started to

fade with the Enlightenment.

It’s pretty easy to confuse the Scientific Revolution with the Enlightenment, but they

are different things.

The Scientific Revolution was a paradigm shift in how we did science, whereas the Enlightenment

was more of a philosophical and religious movement that took place a bit later, often

touted as an extension of the former.

So, even if you don’t care much about space, why should you care about all this?

Well, first off, why don’t you care about space?

Second, while the scientific revolution might not have been a revolution in the traditional

sense, it did still change how we think of the world; and while this may not have been

something initially known about by the common person, the new knowledge brought on by this

series of events did eventually come down to the common person.

Nowadays, not only do we all know how the solar system works, no one would even think

to keep that knowledge from us (at least, no one whose theories actually work out).

It wasn’t just math, physics, and astronomy that saw significant advancements during this

time though, but things like biology and chemistry, which is more helpful in the not-pushing-the-average-lifespan-down-to-thirty

department.

The study of human anatomy expanded from merely the teachings of Galen, who likely never actually

dissected a human body.

This whole paradigm shift can be seen in the motto of the Royal Society, founded in 1660,

“nullius in verba”, meaning “on the word of no one”.

If you find, through your own findings, that an old teaching is bad, reject it and replace

it with a better finding.

Just because something may work somewhat decently, doesn’t mean it can’t still be improved.

This way of thinking, of calling the authority of past sources and high officials into question,

would start to become the dominant way of thinking around the world for the next few

hundred years, starting many numerous revolutions all across the planet.

If you want to learn more about some of those revolutions, might I point out that this video

is actually part of a huge group collaboration between myself and some amazing history YouTubers,

called Project Revolution.
