The first time I seen Carl Sagan I was incredibly impressed by his vast intelligence. but then he was on The Tonight Show with Johnny Carson. again I was impressed by his vast intelligence. but when he was having a conversation with Johnny Carson. I realized that he had another incredible ability. and that was he could educate anyone including me. and from then on I was inspired by him. he was one of the most brilliant minds in modern time's. he is definitely missed.
Algo a lo que se negaban científicos como Feynman, cuando decían que eso sería engañar. O era la explicación especializada,tras años de estudio, como los suyos, o no valía la pena explicar las cosas.
Excellent explanation using Flatland and a Tesseract. A three-dimensional object moving through Flatland would be what H.P. Lovecraft described as "the crawling chaos" as chaotic shapes appear, disappear, reappear. Carl Sagan mentioned that the Flatlander was surprised but rational when an apple visited Flatland. I would say that most Flatlanders would be terrified with some going mad. Lovecraft said, "I have harnessed the shadows that stride from world to world to sow death and madness." This is a mathematical explanation that Lovecraft's fictional alien entities like Cthulhu and Azathoth were multi-dimensional entities which appear as amorphous, shifting, shadowy, and chaotic volumetric shapes which our febrile minds perceive as pseudopods or tentacles, piercing our veil of reality.
Yeah I haven't looked it up but I would expect that his voice was based on Carl a bit. Although Carl Sagan also sounds a bit like Kermit the Frog, so there's that.
In flatland shapes can not be seen. Only imaginary lines can be seen. To see a shape one must stand over it. That is possible only in 3D. So Carl Sagan is wrong.
Carl Sagan was a true genius. He would always explain things to us in a way we could understand. Sucks that he died so young. I'd love to have met him.
@@eugene7518 we all know every 3D object can be described using x;y;z coordinates... if 1D and 2D didn't exist...

Well the Flat Earth Society has been around for quite a while, although initially they were more of a debate group using a ridiculous premise as a base for creative debate. None of them actually believed it, it was just a tool. It was only later that the lunatics annexed it to fortify their religious dogma.
I literally can’t stop crying when I watch Carl. The nostalgia mixed with the tragedy of his death and the societal death of the love and pursuit of knowledge simply for its sake is very overwhelming for me!
And you will seek Me and find Me when you search for Me with all your heart. -Jeremiah 29:13 “For God so loved the world, that He gave His only Son, so that everyone who believes in Him will not perish, but have eternal life. -John 3:16 Repent therefore, and turn back, that your sins may be blotted out. -Acts 3:19 :) :)

@@eugene7518 Ever since man first left his cave and met a stranger with a different language and a new way of looking at things, the human race has had a dream: to KILL him! So we don’t have to learn his language or his new way of looking at things.
Flatlanders have only a side view. They can't notice where length and width meet. Therefore everything appears as an imaginary line. Cause they can't stand over a shape, to see the shape. That's only possible in 3D.
This explanation, (dubbed in spanish) is one of the most vivid memories of my childhood. It made so much sense, I've lived my life not taking anything at face value and looking for the possibility naked to our eyes. Thanks MR. Sagan, your spirit carries on.
So classic, so iconic. And it succeeds in making you wonder about all we could all be missing from our anthropocentric perspective with our constants and comfortable assumptions.
I remember watching this in school but not really paying attention. Now I'm watching it 13 years later so I can understand what I chose not to learn then
In the original Cosmos series, there's a great segment from one of the episodes where Sagan went in to teach a science class, in the same elementary school that he went to as a child. A bunch of 10-year-old kids got to have him as their teacher for a day. The kids looked absolutely amazed and enthralled.
Damn right I did. But the fact that people (who may normally have 0 interest in science) are being inspired to watch videos like this by Interstellar is extremely uplifting.
Wow! This man just blew my mind! The hypercubes shadow or tesseract is what he is holding in his hand. What he is holding IS the shadow of the 4th dimensional cube. He is only able to display the shadow it creates because there is no way of actually displaying anything in the 4th dimension. You can only imagine it. Why? Because we are trapped in a 3D world (what we see). We are incapable of projecting any 4D image. Brilliant!
A 2D flatland environment is literally a "piece of paper" in a 3D world where paper is used to create, learn, and have fun with. The next world up from us owns this 3D world. Our 3D world's mysteries could be a project in the next realm? Could the next world above us be conscious, mental, and spiritual? "I hold it entirely possible that a technology exists, which encompasses both the physical and the psychic, the material and the mental. There are stars that are millions of years older than the sun. There may be a civilization that is millions of years more advanced than man's. We have gone from Kitty Hawk to the moon in some seventy years, but it's possible that a million-year-old civilization may know something that we don't ... I hypothesize an 'M&M' technology encompassing the mental and material realms. The psychic realms, so mysterious to us today, may be an ordinary part of an advanced technology." -J.Allen Hynek Allen Hynek worked for the US Government's Project Bluebook in the 50's and 60's. His job was to interview witnesses, debunk reports, and discourage public interest in UFOs making witnesses look foolish. By the 1970s however he had admitted that the purpose of the Bluebook project was not to investigate, but to create public doubt. For 20 years Hynek conducted these interviews with witnesses right after the report was made. After conducting years of interviews he noticed the witnesses gave peculiar common details of their experiences. Things are changing with regard to public disclosure of UFO phenomena. Sightings are becoming more and more common. As Earth technology continues to advance the evidence points to the only answer that checks all the boxes.
I watched this video years ago knowing NOTHING about Carl Sagan. I come back to it now, and with knowing so much more about this marvelous man, it almost brings a tear to my eye.
This helped me to understand so much and also reaffirms my beliefs of ghost being inter-dimensional beings. Also, I just love the way vintage men carried themselves. So masculine and classy.
Carl was weak and hated reality. The 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. It is clear creation had to be done supernaturally yet it is still denied because people are just too proud to accept that, among other things.
Listening to Carl Sagan is just so soothing. Just something so paternal about his voice, almost like he is talking one to one with you and cares so deeply that you understand the material he is presenting. Such a shame he had to leave us clearly far before he should have. Thankfully we have people like michio kaku and one of sagan's own pupils, neil degrasse tyson.
How I miss Carl and the ease in which he could communicate, there was something about his tone of voice, and easy manner that drew you in, he was truly one of sciences great orators. ❤️
Who needs computer graphics when an apple and flat shapes say so so much more and everybody gets the meaning. Bring back easy learning!! I remember watching this with my family as a ten year old kid but obviously not gettin it but watchin it now it blows me away with its simplicity!! We miss u Carl Sagan.
I am sure everone for a second was like "Oh shit here it comes fourth dimension..." and then Carl was like "No you can't see it." I thought for a second what this was going to be the coolest thing on youtube. Still I loved the feeling I got thinking about it.
Wanna "see" the fourth dimension? Ok, take a laser pen and shine it onto your wall, if you look at the centre of that laser dot you will perceive depth in that dot, that *depth* is the fourth dimension. A glimpse of it. I can't take credit for having discovered / seen this though. I got help from someone.
There should be a free worldwide channel where Cosmos runs indefinitely. I would come back ever so often to be embraced in his immense wisdom and his astounding ability to share that wisdom.
ive watched this clip more times than i would like to admit and now i can recite every line with carl. "...as the apple were to desceeend through, sliiiither by.."
I was (am) so very fortunate to have come upon Carl Sagan-fortunate in that I wasn't born until the 90s. And although I did regularly watch educational documentaries of all sorts alongside my father from the start, I wasn't old enough to effectively seek it out on my own volition until the 2000s. "Cosmos" was decades old and Carl Sagan was not here anymore, at least not in physical form. I must have come upon it on PBS but I was enamored with Carl and with astronomy immediately. I was so young that the only way I had access to Cosmos was by regularly searching for it through the menu guide of our cable provider. It could only look not more than a few weeks ahead. So most of the time my search results for Cosmos would turn up nothing more than "not avaliable." But I always looked. And though very rarely, I would at times find an airing. And would set a reminder. This was my only available access. But I never stopped searching for airings. When I sat down to watch Cosmos, one that I had found and set a reminder for weeks prior, I was always so elated that I was moments away from the episode airing, one that I had been anxiously awaiting for weeks. "Weeks" is a very long time when you're 10 years old. Eventually I'd have immediate access once streaming became more accessible. We had a desktop PC and dial up by 2000 but my parents had 0 ability and 0 motivation to learn how to use one and therefore couldn't navigate it at all, whatsoever. I had to teach myself, which I did. I was fortunate in that my parents did not indulge in the purposely exaggerated, sometimes hysterical "stranger danger" narrative pushed by mainstream media in the days where internet use and access began to skyrocket in regularity in the homes of regular Americans. I was an elementary aged young girl but I had total and complete access to the world in this relatively brand new concept. I used it safely, and effectively. And I've never stopped using it for learning. I've never stopped having such profound gratitude and appreciation for our ability to have instantaneous access to anything and everything. Carl Sagan was my first "teacher" in the sense that he's the first I ever sought out on my own. My first vessel in independent, willful knowledge as an individual human being, separate from the teachers and teachings I encountered in the traditional way at the behest of forces outside myself. Through Carl Sagan I became enlightened to the concept of independent limitless learning.
It always makes me sad to find out about Carl Sagan so late in my late. i mean man, if there ever was a person i would like to meet in real life. it was him. We really need more people like him.
In flatland shapes can not be seen. Only lines can be seen. To see a shape one must stand over it. That is only possible in 3D. So Carl Sagan is wrong.
Carl Sagan had such a profound impact on my life, how I perceived the world, superstition, my love of everything in literature non fiction. I’ve admired many great men in history and in every field of science, but his death was so painful I cried at the knowledge of what the world had lost. A man for all seasons.
That’s awesome you think so. Existence is more interesting if you listen to other fields of mathematics and science. If you like your world that’s great. Me appreciating science and mathematical theories takes nothing from you. So long and have a great existence!
In flatland shapes can not be seen. Only lines can be seen. To see a shape one must stand over it. That is only possible in 3D. So Carl Sagan is wrong.
I love watching these kind of people. They test my comprehension skills. Sometimes I get it and sometimes not but I’m so proud of myself when I do get it. It all depends on who is speaking. With Carl I stand a much better chance of getting it.
This explanation took me back in time in my youth setting in class thinking of riding my bicycle at home and going to the creek to look for arrow heads while the teacher was explaining something that I couldn’t comprehend.
Well, let's make it *really* interesting then! Sagan, during his discussion, is apparently alluding to 5D cosmology. That's been a thing for a while (just do a search on "5D Cosmology" on the arXiv preprint server at the arxiv.org site). As we all know, Einstein's math professor, Dr. Minkowski, laid forth a 4D geometric framework (over the objections of Einstein) in late 1907 and early 1908 for Relativity and electromagnetism - that's 3 spatial dimensions and 1 time dimension; or 3+1 dimensional. What most people don't know however is that tucked away in the appendix of that very paper, which launched 3+1 dimensional Minkowski geometry, was an attempt to expand the geometric picture yet further to be able to more consistently reconcile Newton's physics with Relativity. He added *a fourth spatial dimension* (calling it "virtual displacement") and devised the groundwork for a 4+1 dimensional geometric unified formulation of both relativity and non-relativistic theory, and then started to try and to fit gravity into it at the very end of the appendix. His work was cut short: he keeled over in 1909. It *is* doable (as we found out by the 1980's ... several years *after* this episode aired) and Minkowski was on the verge of finding out how to do it, in 1907. Today, we know it as Bargmann geometry (the natural playing field for Newtonian Physics) and it is *directly* connected to the 5D geometries used in Cosmology, which may be likened to as the relativistic versions of Bargmann geometry. None of that came about until after the 1950's; while Minkowski's appendix was published just before Bargmann himself *was even born* ! That's how far ahead of its time it was.
In flatland shapes can not be seen. Only imaginary lines can be seen. To see a shape one must stand over it. That is possible only in 3D. So Carl Sagan is wrong.
I watched the Cosmos series on PBS when I was about 20. It was broadcast on Sunday evenings and I had to watch it on our old black and white TV on the back porch. This while the living room TV, with everyone else, had either football on, the news or 60 Minutes. I eagerly devoured this series. Bought the book and the record music album. I had an interest in Astronomy since the age of 12 and this series just reenforced that. I took Astronomy 150 at Ohio State (5 credits) and I got a grade of A-. Most of this course in college I self learned prior. That was the best I good do in this subject because the Calculus and the Physics series humbled me.

@@eugene7518 He's not claiming that 4D exists. He is claiming that if it did exist, the 3D "shadow" of a 4D object may be something like a tesseract. He literally said it's impossible for us to see the 4th direction--the impossible direction that is somehow at a right angle to the x axis, the y axis, AND the z axis. It is an abstraction of the concept of dimensions. We live in a 3D world. That's true.
Everything about the original Cosmos was just perfect. The cinematography, the visual effects (for its time), production and direction of Adrian Malone, the music of Vangelis and of course the Presenting of Carl Sagan.

I was in my early teens.
Reading pop magazines.
Studying the next fashion trend.
Like everybody else my age.
Then this guy appeared on tv.
He changed my life around.
I saved up my pocket money.
Then bought THE BOOK.
"Cosmos".
It didn't make me a professor.
It made me think.
In other dimentions.
How many are there ?
If only I could use my brain's full capacity.
Not just a small percentage...
Will mankind ever evolve to that stage ?
Or are we stupidly destroying ourselves.🙊

Are we just an other petri dish experiment to someone out there ?
I think we might be.
And I worry that we're failing big time... 🙉

“There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call the Twilight Zone.” - Rod Serling

@@BeinThatGuy FRANK MARTIN DIMEGLIO HAS EXPLAINED TIME DILATION IN CONJUNCTION WITH PROVING THAT ELECTROMAGNETISM/energy is gravity:
Consider what is E=MC2 ON BALANCE. Consider what is the Sun, AND the stars AND PLANETS are POINTS in the night sky. INDEED, consider what is THE EYE ON BALANCE !!! I have CLEARLY proven and explained what is the fourth dimension.
CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE); as the stars AND PLANETS are POINTS in the night sky. Consider TIME AND time dilation ON BALANCE, AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! INDEED, consider what is the man (AND THE EYE ON BALANCE) who IS standing on WHAT IS THE EARTH/ground !!! WHAT IS E=MC2 is WHAT IS GRAVITY as WHAT IS SPACE. Great.
WHAT IS GRAVITY is, ON BALANCE, an INTERACTION that cannot be shielded or blocked. Again, consider TIME AND time dilation ON BALANCE; AS the stars AND PLANETS are POINTS in the night sky. (I have proven the fourth dimension.) TIME slows down as one approaches the speed of light, as less TIME passes. Great.
Indeed, consider why and how it is that there is something instead of nothing ON BALANCE. BALANCE AND completeness go hand in hand. Magnificent.
I have CLEARLY proven and explained (ON BALANCE) why and how a given PLANET (including WHAT IS THE EARTH) sweeps out equal area in what is equal TIME. Magnificent.
WHAT IS E=MC2 is WHAT IS GRAVITY as what is SPACE !!! Indeed, consider WHAT IS the fully illuminated (AND setting/WHITE) MOON ON BALANCE !!! It IS the SAME SIZE as what is THE EYE !!! The rotation of WHAT IS THE MOON matches the revolution, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Magnificent.

Carl Sagan has a way of breaking down such complex subjects into concepts we can grasp..
Anyone being able to grasp what is being discussed
Comes from someone who truly understands what they are talking about
Generally speaking
The first time I seen Carl Sagan I was incredibly impressed by his vast intelligence. but then he was on The Tonight Show with Johnny Carson. again I was impressed by his vast intelligence. but when he was having a conversation with Johnny Carson. I realized that he had another incredible ability. and that was he could educate anyone including me. and from then on I was inspired by him. he was one of the most brilliant minds in modern time's.
he is definitely missed.
Algo a lo que se negaban científicos como Feynman, cuando decían que eso sería engañar. O era la explicación especializada,tras años de estudio, como los suyos, o no valía la pena explicar las cosas.
Excellent explanation using Flatland and a Tesseract. A three-dimensional object moving through Flatland would be what H.P. Lovecraft described as "the crawling chaos" as chaotic shapes appear, disappear, reappear. Carl Sagan mentioned that the Flatlander was surprised but rational when an apple visited Flatland. I would say that most Flatlanders would be terrified with some going mad. Lovecraft said, "I have harnessed the shadows that stride from world to world to sow death and madness." This is a mathematical explanation that Lovecraft's fictional alien entities like Cthulhu and Azathoth were multi-dimensional entities which appear as amorphous, shifting, shadowy, and chaotic volumetric shapes which our febrile minds perceive as pseudopods or tentacles, piercing our veil of reality.

In the original Cosmos series, there's a great segment from one of the episodes where Sagan went in to teach a science class, in the same elementary school that he went to as a child. A bunch of 10-year-old kids got to have him as their teacher for a day. The kids looked absolutely amazed and enthralled.

He is only able to display the shadow it creates because there is no way of actually displaying anything in the 4th dimension. You can only imagine it. Why? Because we are trapped in a 3D world (what we see). We are incapable of projecting any 4D image. Brilliant!

3D world. Our 3D world's mysteries could be a project in the next realm? Could the next world above us be conscious, mental, and spiritual?
"I hold it entirely possible that a technology exists, which encompasses both the physical and the psychic, the material and the mental. There are stars that are millions of years older than the sun. There may be a civilization that is millions of years more advanced than man's. We have gone from Kitty Hawk to the moon in some seventy years, but it's possible that a million-year-old civilization may know something that we don't ... I hypothesize an 'M&M' technology encompassing the mental and material realms. The psychic realms, so mysterious to us today, may be an ordinary part of an advanced technology." -J.Allen Hynek
Allen Hynek worked for the US Government's Project Bluebook in the 50's and 60's. His job was to interview witnesses, debunk reports, and discourage public interest in UFOs making witnesses look foolish. By the 1970s however he had admitted that the purpose of the Bluebook project was not to investigate, but to create public doubt. For 20 years Hynek conducted these interviews with witnesses right after the report was made. After conducting years of interviews he noticed the witnesses gave peculiar common details of their experiences.
Things are changing with regard to public disclosure of UFO phenomena. Sightings are becoming more and more common. As Earth technology continues to advance the evidence points to the only answer that checks all the boxes.

Listening to Carl Sagan is just so soothing. Just something so paternal about his voice, almost like he is talking one to one with you and cares so deeply that you understand the material he is presenting.

Let's just imagine: The Synopsis for every movie
I used to watch his Cosmos show on my 24” tube TV. Carl Segan was the best.
ive watched this clip more times than i would like to admit and now i can recite every line with carl. "...as the apple were to desceeend through, sliiiither by.."
I was (am) so very fortunate to have come upon Carl Sagan-fortunate in that I wasn't born until the 90s. And although I did regularly watch educational documentaries of all sorts alongside my father from the start, I wasn't old enough to effectively seek it out on my own volition until the 2000s. "Cosmos" was decades old and Carl Sagan was not here anymore, at least not in physical form. I must have come upon it on PBS but I was enamored with Carl and with astronomy immediately. I was so young that the only way I had access to Cosmos was by regularly searching for it through the menu guide of our cable provider. It could only look not more than a few weeks ahead. So most of the time my search results for Cosmos would turn up nothing more than "not avaliable." But I always looked. And though very rarely, I would at times find an airing. And would set a reminder. This was my only available access. But I never stopped searching for airings. When I sat down to watch Cosmos, one that I had found and set a reminder for weeks prior, I was always so elated that I was moments away from the episode airing, one that I had been anxiously awaiting for weeks. "Weeks" is a very long time when you're 10 years old.
Eventually I'd have immediate access once streaming became more accessible. We had a desktop PC and dial up by 2000 but my parents had 0 ability and 0 motivation to learn how to use one and therefore couldn't navigate it at all, whatsoever. I had to teach myself, which I did. I was fortunate in that my parents did not indulge in the purposely exaggerated, sometimes hysterical "stranger danger" narrative pushed by mainstream media in the days where internet use and access began to skyrocket in regularity in the homes of regular Americans. I was an elementary aged young girl but I had total and complete access to the world in this relatively brand new concept. I used it safely, and effectively. And I've never stopped using it for learning. I've never stopped having such profound gratitude and appreciation for our ability to have instantaneous access to anything and everything.
Carl Sagan was my first "teacher" in the sense that he's the first I ever sought out on my own. My first vessel in independent, willful knowledge as an individual human being, separate from the teachers and teachings I encountered in the traditional way at the behest of forces outside myself. Through Carl Sagan I became enlightened to the concept of independent limitless learning.
Great story, thanks for sharing!
I love his humor / sarcasm as he explained in detail, absolute genius!
The best teacher to ever explain science so simple your kid would understand it.

Well, let's make it *really* interesting then! Sagan, during his discussion, is apparently alluding to 5D cosmology. That's been a thing for a while (just do a search on "5D Cosmology" on the arXiv preprint server at the arxiv.org site).
As we all know, Einstein's math professor, Dr. Minkowski, laid forth a 4D geometric framework (over the objections of Einstein) in late 1907 and early 1908 for Relativity and electromagnetism - that's 3 spatial dimensions and 1 time dimension; or 3+1 dimensional.
What most people don't know however is that tucked away in the appendix of that very paper, which launched 3+1 dimensional Minkowski geometry, was an attempt to expand the geometric picture yet further to be able to more consistently reconcile Newton's physics with Relativity. He added *a fourth spatial dimension* (calling it "virtual displacement") and devised the groundwork for a 4+1 dimensional geometric unified formulation of both relativity and non-relativistic theory, and then started to try and to fit gravity into it at the very end of the appendix. His work was cut short: he keeled over in 1909. It *is* doable (as we found out by the 1980's ... several years *after* this episode aired) and Minkowski was on the verge of finding out how to do it, in 1907.
Today, we know it as Bargmann geometry (the natural playing field for Newtonian Physics) and it is *directly* connected to the 5D geometries used in Cosmology, which may be likened to as the relativistic versions of Bargmann geometry. None of that came about until after the 1950's; while Minkowski's appendix was published just before Bargmann himself *was even born* ! That's how far ahead of its time it was.
In flatland shapes can not be seen. Only imaginary lines can be seen. To see a shape one must stand over it. That is possible only in 3D. So Carl Sagan is wrong.
I watched the Cosmos series on PBS when I was about 20. It was broadcast on Sunday evenings and I had to watch it on our old black and white TV on the back porch. This while the living room TV, with everyone else, had either football on, the news or 60 Minutes. I eagerly devoured this series. Bought the book and the record music album. I had an interest in Astronomy since the age of 12 and this series just reenforced that. I took Astronomy 150 at Ohio State (5 credits) and I got a grade of A-. Most of this course in college I self learned prior. That was the best I good do in this subject because the Calculus and the Physics series humbled me.
