>Purely through logic and observation they created new knowledge that was remarkably close to the actual phenomenon In a way, science has come full circle back to this.

Phlogiston theory always makes me wonder which of our current scientific models is totally wrong, but explains things well enough that we still haven't caught it.

[@jacquiecotillard9699]

I feel the same way- that we aren’t missing some inexplicably huge gap in our understanding, but rather our overlapping systems obscure trends that oppose each other. Not to start a whole thing, but the most promising intersectional vector may be theory of mind and body. Scientific materialism’s denial of embodied attention counters the indefinable esoterica of systems like nei gong or qi gong to a standstill, both invalidating each other perfectly. Our limited mastery over the body by science is undeniable, but at no way seeks to enclose that knowledge for immediate use by the embodied. Without these technologies bettering each other collaboratively or even competitively, we are missing out on unimaginable lines of experimentation, for what seems like a simple lack of proper methodology.

All of them are. We cant model anything to the precision of a femto-decimal. So in principle all our models are "wrong" but some are useful for our purposes. Engineers rise up! Praise be to the power of assumptions!

The main proponent of executing Lavoisier was the revolutionary leader and newspaper publisher, Jean-Paul Marat. Marat had gone to visit Lavoisier to push some sort of pseudo-scientific idea. Lavoisier was offended and rudely kicked him out of the house. Marat was, in turn, humiliated and vowed to get revenge. It's interesting that the best known painting of Lavoisier is the one of him and his wife, painted by Jacques-Louis David. Ironically, David made an even more famous painting, "The Death of Marat".

If coal is almost pure phlogiston, and phlogiston has levity instead of gravity, therefore coal should fly around. You can really tell they were grasping at straws with that explanation, even without taking into account modern knowledge.

[@alexrogers777]

yeah the claim that phlogiston had negative mass was pretty obviously just a post hoc rationalization they pulled out of their ass when confronted with the observation that metals *gain* mass when burned

[@BoleDaPole]

Coal is almost pure phlogeston yes, but the parts that aren't weigh it down drastically.

[@Mnemoniforma9.00]

1:23 Worth noting that on the opposite side of Eurasia, alchemists had the Wu Xing, a completely different system of five elements in two complementary phases that interacted in cycles of suppression and generation.

[@perguto]

It's interesting to see how phlogiston theory works surprisingly well as you can roughly equate it with "negative oxygen" or low oxidation states, allowing most statements of oxygen theory to be translated to phlogiston theory and vice versa, e.g. "absorbing phlogiston"="emitting oxygen/getting reduced", "oxygen has positive mass"="phlogiston has negative mass" etc.. Kinda reminds me of how, in electrical engineering, it rarely matters whether current truly flows from + to - or - to +, or of how positrons can be described as holes in the Dirac sea of negative energy electron states

Reject oxygen Retvrn to phlogiston

[@dominictarrsailing]

being able to restore the calx by heating with pure phlogiston must have seemed very compelling. I guess the oxygen moves over from the metal oxide to the carbon The phlogiston antigravity bit made me imagine the lifting power of a phlogiston blimp! probably MUCH more dangerous than just hydrogen. However, if phlogiston is negative mass but coal, which is (almost?) pure phlogiston, is curiously heavy. Thanks for the great video. It's really interesting to learn about the thought process people went through to produce modern science. For me personally, knowing about the history helps me to actually understand that science, a lot more than just learning about what we know now.

[@ewantaylor2758]

The weight of coal was my first thought, too. Even if the other elements gave it some weight, surely it must have been suspicious that the stuff which had the purest amount of negative-weight matter was not wieghtless or at least incredibly light? Goes to show the willingness to overlook a detail in order to make a theory fit neatly.

That was excellent, and I loved the inclusion of so many contemporary sources. I love seeing the reasoning of people from the past, many of whom were quite smart but were missing essential information. Not to mention, for every "phlogiston", you can also find examples of people making surprisingly correct conclusions much earlier in history than one would expect, just from clever reasoning about their observations. It really gives you a window into how a lot of the knowledge we take for granted was learned.

A concept that used to exist in the past, that always resonated with me, is Ether. The concept of The Ether and that the universe consists of an Ether is just a cool concept that i feel could be expanded upon & adapted in creative ways. Giving us ways to explain what make up the different regions of so called emptiness throughout our universe

[@Arbyjar]

I agree, but I actually like the experiment disproving it as a medium for light even more. There’s no reason to say that ether can’t exist, but not in the way it has been described historically. On a more physics-esque note, ether could be the new name for the fabric of space-time, or maybe the Higgs field?

[@benmcreynolds8581]

@Arbyjar Exactly! You get it! It's refreshing to read your reply. That's exactly how I've liked to ponder about this. Taking the classic concept & converting it into a new accurate realm instead of all that previous inaccurate alchemist type stuff. This is just a fun thought experiment but I feel like it'd be possible to create multiple types of accurate categories of Ether.. I know that's a loose way to describe it.. but here's some vague examples: There's the category you already mentioned, then there could be separate layers of Ether. Like a way of describing different regions with different particle densities. Maybe even to describe different atmospheric contents. All I'm trying to say is there is different amounts of particle densities throughout space. Even in the so called vacuum of space. We recently learned there is a "bubble" around our Sun, around our solar system consisting of solar wind, charged particles in the Heliosphere. Just imagine what we have yet to discover around galactic clusters, nebulas, etc. etc. I just think there's depth to this niche and ways to utilize an old inaccurate term and turn it into a new accurate useful term

Dark matter isn't a theory, it's a series of observations. There are theories of dark matter but dark matter itself is not a theory.

[@lunatickoala]

​@@terrestrialTerror The name "dark matter" is misleading because the observations are gravitational anomalies. They could be the result of particle dark matter, they could be the result of needing to modify our understanding of gravity, and there's also the nightmare scenario in which both are true. But the name implies that it's particle dark matter and theories like Lambda-CDM have "dark matter" in the name. One suggestion I've heard is that the series of observations be called "Dark Gravity" to clearly differentiate the observations from the theories. To someone who isn't well aware of the distinction, it sounds absurd for someone to first claim that "dark matter" (the observations) has been seen over and over and is irrefutable while "dark matter" (any of the particle theories) is unproven. And undoubtedly some people who are aware of the distinction still think it's a lousy if not absurd name.

I think aether was prematurely rejected. We know that light travels at different speeds in different media. Therefore a medium can slow light. We've long known the speed of light in "empty" space, but we now know that space is not empty. Might light speed be instantaneous were it not for some limiting substance or energy in so-called empty space? Might the just-discovered Higgs Field, or something else not quite yet discovered, be that aether that was once conjectured? Otherwise, why should there be any limit on the rate of propagation of electromagnetic waves?
