The Presocratics: Crash Course History of Science #2

[@SuperCaleb283]

The little giggle before he said "This is so great" made me smile ear to ear. You can FEEL how much he's loving this series and I'm so glad that he's sharing this awesome passion with us! Crash Course is amazing, and I'm really glad that they're doing History of Science.

Maybe we can help spread it further by translating the subtitles.. I see this one have no Arabic subtitle yet, 🤔

@@armanke13 there is a version of crash course world history in arabic, with a different host who is I assume a native Arabic speaker, just an FYI

[@dotsandprintsdesigns4731]

I'm 23, kinda done with studying for a bit... and at school I DIDN'T always love studying (which was how it felt...as opposed to learning) and now I can't stop watching your videos and I'm so restless, I wanna learn so much! About math, science, philosophy and everything under the sun! All of this made me a much better person and thank you for sparking this interest in me (or making me realise how incredibly nerdy I am... I don't even enjoy mainstream cinema anymore... only documentaries.. I think this will continue until I feel at least a little satiated with knowledge) You truly make this world a better better better place! Thank you

[@feynstein1004]

Crash Course is a national treasure. They should definitely do a series on logical reasoning. Everyone needs to know that. Like how to read and write.

If this was true we haven’t even started first grade 😂

[@NeroVuk]

@@bantober careful now, rhetoric like this is used by clueless people to dispute well established scientific facts like the theory of evolution for example. Of course, there is much to learn, but we also know a lot, for example we know how to communicate via computer which is essentially magic.

HOW DARE YOU SPEAK OF THE SQUARE ROOT OF TWO IN MY BEAN LESS CULT!

[@nickj5451]

How is this wonderful comment not drowning in praises? This comment deserves to be preserved in a fragmented form for the archaeologists and scholars of the next millennium to ponder. This Most-Worthy Comment will remain unknown to them until a determined deserter releases it from its eldritch brotherhood, saying, "Kill me though they may, the people deserve to know!" The comment will rest in the desk-drawer of a narrow-minded official who will laugh and think nothing of it, until ten years later his daughter discovers it one day, saying, "The world is not ready for this." "This comment cannot exist, it cannot be" will be the only words of her otherwise speechless colleagues. They will deliberate many months how to let it spread and take hold among the public before the authorities have the chance to quench it. "Is America ready for this comment?" will be the headlines of mainstream news stations nationwide, while international leaders mock the U.S. President's desperate attempts to maintain the credibility of the country's bean industry. And although the government will carry on business-as-usual, who, through a series of diversion tactics, establish this comment as something against polite conversation, there will always be truth-seekers holding it squarely before society's conscience. "For the Root of Truth runs very deep, Yea, deeper roots than any bean."

[@pathoesr7872]

Rhetoric is the art of language and ancient Greeks loved it. It was a sport for them. I'd be really happy if you could do a crash course on that topic at some point in the future (I'd be happy to network you to resources). People always refer to it as "propaganda" or misunderstand it to be something like "pretty words," but it really is much more than that.

[@sirmeowthelibrarycat]

Pathoes R 😺 Indeed! Rhetoric was and still is part of classics education in schools and universities to this day. It was highly regarded as an accomplishment by Romans such as Seneca. Unfortunately, today all too often what we hear is a torrent of word salads and vacuous pontificating.

[@pathoesr7872]

Sir Meow The Library Cat , thank you! It really is an important part of education. Honestly, I was surprised that a number of the practical skills they tried to teach me in my high school English class was rooted in it. Back then, I thought it was pointless. Turns out they were trying to teach me what a "tree" was without calling it a "tree." That's all well and good if it was actually a tree. A tree is a physical thing that you can show me. But if the world was sterilized and there were no trees, or records of trees then your just left with an idea of a "tree" as an abstract thing. Calling it a "tree" becomes far more important in that circumstance to retain the entity of "tree." Our words are important.

*full of excitement* "This is so great" Hank is so adorable

[@nashimaguinaresmail3765]

Contradiction has always been an exciting part of learning, and thru these greek philosophers, they embodied with such a genius way of deliberating different theories and principles of one another. Thales, without being irreligious is really a pro for founding the Milesian school which opened the doors for greek amateur scientist such as Empledocles, Anaximander, who later then disproved Thale's water substrate theory to an apeiron one. How I wish I could witness their debates and all. Pythagoras, being more mystic thinker compare to Milesians, he believed in idealism that aspires to create an abstract model of perfect stuff. He is way being an idealist for creating something out of his vivid imagination and justifying them. Idealism was never bad at all. Democritus, who argued with Zeno about his idea of Atomism is an excellent and brave way of proving for what he believed in. Yes, it sounded weird and funny to hear what is between the atoms of the void, so much interesting! This school of thought was a brilliant idea for opening irrational debate in dealing with arguments and contradictions, even a up to this time, science yet did not end up with absolute TRUTH. Always exciting to know more of their stories.

[@acetate909]

The scientific method and its resulting body of knowledge is the greatest achievement humans have and ever will accomplish. How inert matter was able to coalesce into a concious system that in turn allowed it to reflect into itself and ask "why" is beautiful beyond comprehension.

[@zhoeypm1750]

This episode gave me a tour way way back to history. I learned so much to these presocrates philosophers. I'm amazed to them, who are trying to separate myth from the truth and developing valuable methods that we use today. They shared thoughts and learnings to our world that made us moving on from being arrogant such as Thales who separated the world from the divine, Anaximander's formless initial state called the apeiron, pythagoras introduction of idealism to science and democritus' knowledge atoms

[@sofiesvideothing7439]

This brings such joy to the scientist in me! I really hope that you'll do a whole episode on Alexander von Humboldt! I absolutely love what you are doing and it is shows like these which make me sad that I don't speak english absolutely fluently, so prospects as a scientist communicater seems dim.

[@Lucky10279]

What's kinda amazing is that we still don't know if atomism is true. Sure, what we now call atoms are definitely NOT indivisible, but scientists are still now trying to figure out if there is actually a single sunstance that makes up all the others. String theory is one theory in favor of this idea.

[@Heulerado]

They are also trying to figure out whether space and time are infinitely divisible, so maybe there are atoms of space and time!

[@Lucky10279]

This will be a great series! All of this episode and more is in Bertrand Russell's History of Western Philosophy. Couldn't believe Pythagoras had his own philosophy school. I just thought it was some guy who gave us a theorem.

[@failedleopard3685]

I hope you guys will mention Hero(n) of Alexandria in this series, the guy who pretty much came up with the first steam engine (the Aeolipile or Hero's Engine) about 1700 years (In 10 AD-70 AD) before the rest of world! Just imagine if someone had made the industrial Revolution happen at that time!

[@AmandaFromWisconsin]

FailedLeopard Are you one of those "white people never really invented anything" people?

[@varana]

But Heron really maybe deserves a passing mention as a fun fact in this, nothing more. He invented something (or at least he wrote the first surviving text that mentioned it) but didn't really contribute much to science as a whole by that (or even technology - his apparatus was mostly a curious thing, it had very little practical use in its time).

[@EmanuelMay]

Except that he (if I remember correctly) also designed the Pharos, the great lighthouse of Alexandria, which was indeed quite the engineering masterpiece and used a lot of things, like parabolic mirrors that were maybe known but not quite common back in the day. But yeah, he was more of an inventor and engineer, less of a theorist.

[@varana]

He didn't, though - the Pharos of Alexandria is attributed to Sostratos of Cnidus. We also know fairly well when it was built; the time when Heron lived, on the other hand, is quite disputed but was certainly after the Pharos' construction. :)

[@jessebrace1128]

Daaaang! I've never seen Thales thrown under the bus like that! Usually the story goes that Thales rejected worldly desires in favor of doing philosophy. The reason he cornered the market on olive oil was to make the point that getting rich was trivial and easy, and that doing philosophy was a more noble pursuit.

I think this series might be my favorite.

[@philp521]

Anaximenes certainly belongs in the Milesian conversation. Whereas his teacher, Anaximander, thought “the archae” was Apeiron, Anaximenes proposed that it was aer, or air/breath/wind/mist/etc., arguing that condensation and evaporation taken to extremes could explain its transformation into fire, water, or earth. This was significant in that it was the first scientific theory that made an effort to propose an entirely natural causal element, using only things that they had evidence existed. As far as there is textual evidence to support, he was the most sophisticated thinker of the Milesians.

[@subutaynoyan5372]

Fun fact: Anaximander thought Thales' theory of water just pushes the problem of explaining how the world works further. Not explaining anything about it's origins. So he came up with the idea that the World, isn't necessarily supposed to be on top of anything.

[@juliantreidiii]

This does leave out the fact that the concept that everything is made of water derives from the ancient Egyptian belief that everything is derived from Nu or some part of water.

Thales sounds like he may have been on the verge of tectonic plate theory with his floating land on water colliding to make earthquakes idea.

[@rainydaylady6596]

I was thinking something like that as well. 😊

[@vishnuburla4434]

Thales didn't literally mean everything was water. He was doing metaphysics (the search for first principles). water (condensation, evaporation,, fluid movement, etc.) was the PRINCIPLE behind all of nature (when water evaporates it leaves solid salt so solid "comes" from or "made" of water). The contintants move according to fluid motion so he was right...but was he every wrong just because we now claim land rest of lava not literally water? Thales created a rational materialistic theory of nature and no different then science other than complexity, in "principle."@@rainydaylady6596

Greek and european philosophers who practiced natural philosophy were basically the starting point on the history of science. Amazing people really. Without their theories and ideas we would have a difficult time understanding our world/nature today. Kudos for their works.

[@jeamilainidal714]

I find this video at first borring, like "here we go again, these nerds came up to discuss only one thing." But now i realize that I am strongly wrong in this matter. The nerds that I called were actually the one who made us to get started on. Long years ago presocratics work very hard to separate their beliefs on myths from what they actually knew about nature. Presocratic werent scientist in our modern sense but they have a big contribution on todays how to think stuffs. Presocratic spread their ideas and inspired students to built in the happening of nature and to aquired knowledge. If they werent share it, we will end up all dumb, i guess. It is cool to think that the rational debate is their primary method to gain knowledge, up to now we use debating in order to express our disagreement and convincing people on our rights and this is all thanks to presocratic philosophers. This stars philosophers namely as thales, anaximander, empedocles and phytagoras have different ideas in expressing how the universe came up. All of their content are debatable that is why they were against and neglect each other ideas. I conclude that although this great philosophers have different thoughts/ theories, they gave us big impact in knowing science.

[@fatmahsumayyahlangco7971]

this is an excellent lecture because of this host (Hank Green) recall me the atoms, how Democritus explain it and how he failed to prove it (the void between the atoms). Well some of the lecture mention in discusion is not totally familiar for me. like for instant when Democritus and Zeno argue about atoms. According to Democritus everything is made of little indivisible bits of stuff I call them atom, so Zeno answer it. then what is between the atoms then Democritus says nothing and then Zeno anwser it, if everything is made of atoms but then what is between the atoms of the void? (Hank Green) Also I found out that Pre-socratics is nerd and also I found out how pre-socratics very curious about the world.😅😀 This lecture is awesome because of the knowledge I can get. I'm really excited to the next episode.😊😊

[@kimberlydemata5747]

The Natural philosophers helps us and give us the their ideas and meanings of all the problems. By using Rational Debate.The Natural philosopher must convince the people by using logic,observation and reasoning so called Ratinaol debatw which is logically the abstract to prove your ideas or hypothesis. I also like the argument of two natural philosophers which is Democartis and Zeno. Democratis claims that everything is made up of atoms that cannot be destroyed nor created, always and motion ,infinite in numbers and it comes to different sizes and shapes. Zeno replied to Democractis that what is between in atom since Democratis tells that all things is made of atoms. That really gives me alot of questions of my self and I really enjoyed the past episode in this channel. Thank you for recommending us this Channel.

[@PhilPhysics]

CrashCourse, It seems you are implying (and to my delight) what I've been researching as of late: An idea known as a "universal organizational science". If CC, and Hank, are being so bold as to suggest that philosophy and science are inseparable in terms of science's history, I DEMAND (Repeat, DEMAND) that the last series of Crash Course be one of a "non-crash-course" nature; a series that suggests an idealism centered around a unification of all "science" (under both definitions that this series puts forward!) It's been my very aim [and my goal in my college education] to create this universal science to help assist (if not spearhead) a institutional education system that can accompany public education as a supplement such as Crash Course [and Khan Academy] have given me. Thanks for listening, Mitchell DeSemple

[@joshbobst1629]

The Universal Language? There's another guy been working on that for a while now. Wolfram, I think his name is? Follows Leibniz. And Galileo.

[@lllCockroachlll]

The unification of all the sciences has been tried since early in the 20th century. Logical positivism, logical atomism, Charles Morris, etc. I don't think it has been successful.

I love your videos! I would just like to add that I think Pythagoras didn't rule out all beans, only broad beans/fava beans because they had caused some fatalities. Nowadays we know that favism, the severe hemolytic anemia, occurs only in susceptible individuals who have inherited a deficiency of an enzyme, glucose-6-phosphate dehydrogenase. This genetic trait occurs among people of the Mediterranean region. Most individuals have this enzyme and are not affected. In Greece there are still people who are not aware of the details so they just avoid eating broad beans/fava beans.
