This was the best Star Talk that I've heard, ever. Many of the episodes have interesting guests, but Seb's conclusions and observations are quite relevant for today, as in 2020-21. Tyson let Seb speak much more than other guests, and the comedic person barely spoke. I think that Seb should come back sooner rather than later, and it could be a longer episode.
The history of science is fascinating. Reading a book right now which is specifically about the birth of modern science calling "The Invisible College".
Great episode. Best invention in the middle ages was the mechanical clock. An improved device who's predecessor maybe the antikytheran machine from the Greeks. Who's with me?
the Arab engineer Ibn Khalaf al-Muradi in Islamic Iberia in the 11th century, he invented this amazing geared clock. it was a water clock that employed a complex gear train mechanism, including both segmental and epicyclic gearing, capable of transmitting high torque. The clock was unrivalled in its use of sophisticated complex gearing, until the mechanical clocks of the mid-14th century
I could listen to Seb talk about history and science of the middle ages for hours. Definitely makes me want to get his book because everything he discussed was fascinating.
This was another brilliant #StarTalk! Yet, understanding science history is as important as it is today's understanding of science. Please, develop on this thread! My regards,
Oh man what an episode I love it. Epic questions and my heart is racing I don't know why. Might just be because of the excitement haha more of mr medieval guy please.
Also Anna from frozen I think she liked to walk on the streets. I suspect these lines were written by new yorkers cuz we all know the "space in California" XD
neil making a happy face when seb falk said that the astronomers are the first people to use hindu-arabic numberals IS EVERYTHING. what a geek. i love this man 😍
Two brilliant Brits (‘Ma people’ in Neil’s voice) and the jewel in Americas crown- Neil, what a match made in heaven. This was brilliant and fascinating 🇬🇧🇺🇸
By far one of my favourite StarTalk videos yet! I absolutely love science and history so I was sold on the title. But then the Islamic references thrown in were such wonderful bonuses. I'm a Muslim of ten years now and I like to think I might be Neil's number one Muslim fan. I'm working my way through the entire StarTalk RUclips collection. Started from the oldest video and here I am a few years later!
As long as new things were "invented" during Medieval times, science was there too! They may not have called it "science" and may have even referred to some of the things as "magic" or "work of the devil" but by definition, science was well present back then too.
Back then it was called Natural philosophy. The first use of the word science was in a book by Giordano Bruno and others caught on later then took credit for his idea. But realistically the concept of invention and using math and geometry to do what would have been otherwise impossible goes back as far as the ancient Egyptians, possibly further. Scientists today still don't know how they built the pyramids.
I'm thinking that if one could time travel back while avoiding the plague they would be seen as a "Merlin" as well. A quote comes to mind... “Any sufficiently advanced technology is indistinguishable from magic”. Arthur C. Clarke
Still always learning even with how things are nowadays. The surprise realization of past and present just keeps amazing me. The point of perspective reference through space and time... "For they wash not their hands" comes to mind...
Well, really glad that Neil de Grasse organized this talk, making the huge discovery that there was intelligence, culture, technology, reason, and embryonic science during the late Middle Ages. Better late than never.
“Fascinating, but I wouldn’t want to live there”. About Middle Ages. Paraphrasing Dr. Tyson. NY is fascinating but I wouldn’t want to live there even though visited many times. Another awesome episode. :)
Excellent chat! Please invite Seb back for a second episode 👍 What Neil said about penmanship is so true. I live in Europe and can say that the vast majority of people I work with are unable to write clearly with a pen, I have to insist that they type everything. It’s sad. PS I just ordered Seb’s book - it looks fascinating!
In America we don’t really care about it. But I definitely stress it to my kids to have great penmanship. I tell them if you can’t read it no one else can either so write it neat once or do it 1000 times until you do. I have a third grader and a 6th grader. And both improved their penmanship. It’s very important. Very.
@@malcolmboy21 Indeed! A basic life skill, I would say. I was lucky in that regard as my father was a professional calligrapher, so we grew up around fountain pens 😃
Bought the book, very interesting topic! I couldn’t help but feel Neil was doing exactly what the author was writing against: looking down on/belittling the past. Hopefully this will change that! Side-note: Augustine *DID NOT* take Christianity from a cult to a religion, he was very influential on western theology, but church structures and creeds were already well set in place before Augustine was even born!
27 minutes in, Okay, let's get started on the video... LOL, I was just loving the conversation and didn't even notice no questions had been asked yet.😁
I agree ... but ... When neil interrupts usually adds something to the conversation but sometimes when Chuck interrupts it's a bit too much. I love them both and i learned a lot of things from Neil. At this point i think it's a meme for us fans for this, at first i kept noticing this and thinking it hurts the show but honestly that never happens and i enjoy it. I understand it's a more casual conversation and i bet 99% of viewers (included me and probably you) and most of the guests manage but there were a couple interviews where the guests looked annoyed. No one is perfect and i think we should be grateful for the knowledge Neil provides us and Chuck is the cherry on top of the cake. Happy holidays!
I kinda agree with him. I think the information today is more about trust issues. Trusting the wrong sources. Like looking to Facebook. Or trusting your biases. And not understanding scientific consensus. You see scientist arguing and you think they don't know what's going on. Or you think if they can argue, my made-up idea that popped into my head 3 seconds ago is just as valid. I think if you're a non scientist, getting access to information isn't straightforward. I mean. Sure you can go to school, read books, watch neil. It's not impossible. I just mean. I know how to read and interpret a scientific paper for the most part because I am a scientist. But like my uncle buck. He has no idea. The only way he's going to learn is from someone telling him. Miss information is not just online that has misinformation. Ads, printed works. Etc. Etc. It's all over the place. Unfortunately, some people want their agenda pushed forward, and sometimes thats just hard to see through. Even when you're educated on the topic. Let alone if you're not and have limited know-how on obtaining it. There's just so many times... fats bad! No sugars bad! No it's this other thing thats is bad! Oftentimes, if you dig deep enough, there's someone pulling strings behind the curtains trying to push changes that aren't always sound. I could list hundreds of examples. Or times when scientists were used by the government to do substantial harm to the public. A lot of the people I talk to about things like climate change or whatever. They think it's all about money power and control. You need to look at these people differently. It's likely not an intelligence problem. It's an unwillingness to listen because from there perspective.. YOU are the one selling the snake oil. They are defending against you. I'd argue that muss information is not a new problem. It's been around forever. And the state of things are probably better than in the past and it's not as bad as you think.
I think you should look at the work of Joseph Needham, a Cambridge scientist who spent much of his life discovering the scientific history of China. Among the things he found (documented in an encyclopedia length set of books) is that the first compass was in China and the first mechanical clock was built in China during the Song dynasty. Also, much of this technology was probably taken along the Silk Road. I just think too many of us view the Greco-Roman, European history as World history, when half the world was discovering a lot of stuff during the last 2000 years. Because the Earth is round, there were people living where the Medieval maps said dragons were there! Just because their discoveries weren't written in English doesn't mean they didn't happen. Also, I can't believe, even when your guest mentioned predicting eclipses and you had discussed King Arthur, you didn't bring up Mark Twain's Connecticut Yankee in King Arthur's Court, in which predicting an eclipse is a major part of the plot. I don't think most people would be able to figure it out, when an eclipse happened centuries earlier.
And keep looking up. you made me think of when i was a kid, PBS watching Dr. who. the next show was about the night sky. one time a week i get to stay up watch both. parents sleeping i sneak out and look at the stars. scared and amazed. best time of my life thing back on it. so much fun still to learn about.
Great topic and invaluable knowledge shared by Sebastian. Surprised and a bit disappointed by the "downgrade" jokes that Neil and the other person (cant remember his name and his contribution to the talk to be fair) did through the whole talk. Hope you are reading all these similar comments down here.
l loved this discussion, the subject matter is very interesting. l feel that Neil interjects more than necessary. l am distracted from the idea being discussed by the interruptions.
I think that today's scientists are often running the danger of underestimating people from the past. Folks were not necessarily dumber because they lived long ago. Sometimes, it takes really ages to develop things and ideas. We should be aware that the situation we live in right now is the product of blood, sweat and tears (not to mention earth, wind and fire) of the people before us. I often sense a touch of ridicule in modern scientists, that is completely unjustified.
It's kind of amazing that it took us so long to create the combustion engine. They understood fire and mechanical movement in the middle ages. The one thing they didn't know was how to refine oil into gasoline, but they did have grain alcohol i believe which would have worked for a fuel source. So really, the combustion engine was just sitting there waiting to be invented for hundreds of years before anyone finally did it. Imagine how different things would be if we'd discovered it back in the middle ages.
I feel like astronomy and geology are so intertwined, native americans put fish in harsh soil... I imagine so many cultures have. I loved the service member talking about getting her PhD and the geology if the moon so much ... @startalk can you maybe have him back with a researcher of the medieval times in Africa ? it would be so cool to see them discuss different styles of teaching, math, day to day life and farming or from rich -peasant. As a completely separate topic ideas 1. Can you pretty please talk of the vast geology of the appalachian mountains.... how they were huge and were worn down... how they were surrounded by ancient rock and reef, some before the Colorado rockies existed? it would be cool to ask if there was more space debris 30 million years ago 2. (full disclosure Im as light as these two and Cuban Irish) Can we have someone who will talk about African naval vessels and the gulf stream I really feel like there is something missing in history. I am dying to hear a discussion amongst great trusted minds.... If Africans had specialized boats of all kinds and 'the pyramids' what is to say that us Europeans were just not in the know? Some say the vessels were to small, yet some looked just like Polynesian ones (not to mention not having the Pacific ring of fire) I would really love to know, it is the thing that keeps me up some nights.. love Teresita in Massachusetts N.Camb
Speaking of "human communication" as integral to creative thinking and science, the printing press by Gutenberg (preceded in China) began the world spread of literacy, which of course promoted the flowering and exchange of ideas. (Of course, this was in the last half of the fifteenth century, so technically may be not part of "the middle ages"?) Great episode!
Alchemy, Blood Letting, Abiogenesis, Harmony of the Spheres, Humors and Melancholia, Vitalism, Ether, Polymaths and all that stuff. I have moved past my interest in medieval but still got many people trying to understand that.
Hi Neil and Chuck. I have a question regarding Black Holes. What if Black hole is not a gravity well with a singularity. Rather it could be a tear or damage in the fabric of space time created due to the incredible energy of a super nova. An all the matter that falls in goes to some other dimensions or universe. And as more matter fall in the black hole the torn part gets larger and larger and that's why it appears larger to us after consuming lots of matter. And the light we see around the incretion disk may be the matter and energy that is not going through the torn part. Please answer my question if possible.
There's a problem with that idea: If indeed it was a tear in space, why isn't space just shaped weird around it, like we were looking through the hole in a donut? Why does it completely obliterate electromagnetism, and why do they /all/ do this..? One understanding is a little in your direction, though: It can be argued that a black hole is actually a whole lot bigger inside the event horizon than what we see; that it is internally expanding at a rate which might actually exceed c, like the visible universe likely did during the period we call the inflation.
I think space is shaped weirdly around a black hole because it definitely distorts the fabric of space. And regarding the fact you said about electromagnetism I don't have enough expertise on the subject.
@@gudda7200 The thing about space is that it doesn't rip. Pull it and it expands, push it and it keeps the expansion, but adds "wrinkles". But we're in there absolute weird part of the forest ;)
I hear the bit about Jason the truck driver heading back to the medieval time period, and I'm reminded of the old Transformers cartoon where they end up back around 534 AD. Apparently the episode was called A Decepticon Raider in King Arthur's Court.
You can tell how badly Neil wants to talk sometimes but this guy is very passionate haha this was incredibly interesting though, glad he was so passionate
Dr. Tyson, I've noticed that the circle is a common shape in nature. Many events; craters, calderas, sink holes, fairy rings and ripples are all circles. Is it a rule that natural circles are always indicative of a single event?
I’m a historian, and the fact that Neil DeGrasse Tyson is so curious about the past, it’s heartwarming 💜
Always wanted to major in history. Just afraid there’s not many opportunities if you don’t wanna teach
I have always maintained that the past defines our present, and the present defines our future. Shout out to all historians trying to present things without the help of the main protaganists. 🙏

I'm surprised Neil didn't do a short video (perhaps one of his explainers) on the Jupiter Saturn conjunction this week.
Perhaps because he knew it’d be much less impressive than people were led to believe.

It's kind of amazing that it took us so long to create the combustion engine. They understood fire and mechanical movement in the middle ages. The one thing they didn't know was how to refine oil into gasoline, but they did have grain alcohol i believe which would have worked for a fuel source. So really, the combustion engine was just sitting there waiting to be invented for hundreds of years before anyone finally did it. Imagine how different things would be if we'd discovered it back in the middle ages.
measurements and machining needed to make combustible engine. they had neither
Have a Merry Christmas Neil and Chuck
I feel like astronomy and geology are so intertwined, native americans put fish in harsh soil... I imagine so many cultures have. I loved the service member talking about getting her PhD and the geology if the moon so much ...
@startalk can you maybe have him back with a researcher of the medieval times in Africa ? it would be so cool to see them discuss different styles of teaching, math, day to day life and farming or from rich -peasant.
As a completely separate topic ideas
1. Can you pretty please talk of the vast geology of the appalachian mountains.... how they were huge and were worn down... how they were surrounded by ancient rock and reef, some before the Colorado rockies existed? it would be cool to ask if there was more space debris 30 million years ago
2. (full disclosure Im as light as these two and Cuban Irish) Can we have someone who will talk about African naval vessels and the gulf stream I really feel like there is something missing in history. I am dying to hear a discussion amongst great trusted minds.... If Africans had specialized boats of all kinds and 'the pyramids' what is to say that us Europeans were just not in the know? Some say the vessels were to small, yet some looked just like Polynesian ones (not to mention not having the Pacific ring of fire) I would really love to know, it is the thing that keeps me up some nights.. love Teresita in Massachusetts N.Camb
Speaking of "human communication" as integral to creative thinking and science, the printing press by Gutenberg (preceded in China) began the world spread of literacy, which of course promoted the flowering and exchange of ideas. (Of course, this was in the last half of the fifteenth century, so technically may be not part of "the middle ages"?) Great episode!
Merry Christmas startalk crew, to the big names and small you made 2020 decent
Excellent! Great guest too!
History is a supplier of examples of how the "approximately" (15) logical fallacies were not applied or considered to avoid analytical errors.
Alchemy, Blood Letting, Abiogenesis, Harmony of the Spheres, Humors and Melancholia, Vitalism, Ether, Polymaths and all that stuff. I have moved past my interest in medieval but still got many people trying to understand that.
I knew all this even before watching this video :)
Merry Christmas guys love one from New Zealand
In our modern world, can we keep that kind of sense of wonder alive?
the past is remembered for multiple reasons. "always remember, never forget"
Hey, do one episode on Indian ancient science pls, it's a bit interesting from aryabhat and different sagas
I would've loved more this episode if Chuck was there.
loved to see some debunking i was worried at first, very insightfull guest
I watch the documentary "Monty Python and the Holy Grail"
So i know what mean a woman weigh as much a duck
"You must be a man of Science..." LoL
But do you know the weight of an unlayden swallow?
@@alenefitzgerald4454 Afrikan or European?
Arh yes the Monty Python team , it’s also my ‘Goto’ for all my Science & History knowledge 😂😂😂
If she weighs the same as a duck, she’s made out of wood, and therefore, a witch!
Chuck really needs to get some sun.
As a woman this topic makes me bristle! Happy holidays everyone. Thank you Neil! 😉👍🌕🌠🥇🎄🎁🌟
Hi Neil and Chuck. I have a question regarding Black Holes. What if Black hole is not a gravity well with a singularity. Rather it could be a tear or damage in the fabric of space time created due to the incredible energy of a super nova. An all the matter that falls in goes to some other dimensions or universe. And as more matter fall in the black hole the torn part gets larger and larger and that's why it appears larger to us after consuming lots of matter. And the light we see around the incretion disk may be the matter and energy that is not going through the torn part. Please answer my question if possible.
There's a problem with that idea: If indeed it was a tear in space, why isn't space just shaped weird around it, like we were looking through the hole in a donut? Why does it completely obliterate electromagnetism, and why do they /all/ do this..?
One understanding is a little in your direction, though: It can be argued that a black hole is actually a whole lot bigger inside the event horizon than what we see; that it is internally expanding at a rate which might actually exceed c, like the visible universe likely did during the period we call the inflation.
I think space is shaped weirdly around a black hole because it definitely distorts the fabric of space. And regarding the fact you said about electromagnetism I don't have enough expertise on the subject.
@@gudda7200 The thing about space is that it doesn't rip. Pull it and it expands, push it and it keeps the expansion, but adds "wrinkles". But we're in there absolute weird part of the forest ;)
Hey Neil & Chuck & everyone at Startalk, love your videos 🥳, could you as a guest get Daniel Tammet the brainman savant,
I really really like Seb, what a nice calm guy
I hear the bit about Jason the truck driver heading back to the medieval time period, and I'm reminded of the old Transformers cartoon where they end up back around 534 AD. Apparently the episode was called A Decepticon Raider in King Arthur's Court.
You can tell how badly Neil wants to talk sometimes but this guy is very passionate haha this was incredibly interesting though, glad he was so passionate
Dr. Tyson, I've noticed that the circle is a common shape in nature. Many events; craters, calderas, sink holes, fairy rings and ripples are all circles. Is it a rule that natural circles are always indicative of a single event?
The science 🧪 will be moving with the time’s, and new discoveries, which gives more explanation to the scientific theory
