For those asking how to get to Antarctica: we booked with Hurtigruten (as paying punters) on the MS Roald Amundsen. Highly recommended. Details here: standupmaths.com/antarctica (Not sponsored but I do get a referral fee if you book via that link.) Brace for more Antarctic videos.
Considering that the Moon rotates counterclockwise around the Earth (when seen from Polaris): does the Earth rotate counterclockwise around the Sun? And does the Earth spin counterclockwise around its own axis? (It is said that Venus rotates "backwards" around its own axis, when compared to the other planets, but no-one says wether the "right" way is clockwise or counterclockwise.)
At first, I was astonished! Then I was delighted; it's Antarctica! Then I started to feel sympathetic pain at how cold I imagined Matt's head must feel.
I mean, you HAVE read 20,000 Leagues Under the Sea, right? They clearly mention this sea after the days and days of carbonic acid in the air in the sub.
Technically, the area where you can experience 24h sunlight is slightly larger than the arctic circles, wheras for 24h darkness it's slightly smaller, thanks to atmospheric refraction. But damn, what a commitment to seeing some expensive clouds :-) Great video!
@@okaro6595 I can tell you will understand me when I claim that about 60% of the Moon's surface is visible and photographable from the Earth. Matt needs to do a video to explain this. There's more than one reason for this fact. Maybe Matt could go to the Moon to explain this fact.

@@mimzim7141 There is a Finnish cartoon where a villager is telling tourists: "If you stand tip-toe on the top this hill at midnight, you should be able to see the midnight sun."
Could have group chartered a jet. With the insane costs of a cruise to Antarctica a jet from SAR or Chile would be just as feasible, and guaranteed above clouds.
"It was light, it got dark, it got light again" also perfectly described the 1999 French eclipse I drove about 10 hours each way to see which was also completely clouded over. Better luck to both of us in the future!
The zone of totality went straight through my home town of that eclipse and we had perfect weather on that day. My family from different parts of the country gathered at my home and we watched it together, it was great.
Ditto for the Mexico eclipse I traveled to Mexico City to see in 1991. Teotihuacan (site of the Pyramids of the Sun and Moon) seemed to be the "best" place to be ... but a brief rainstorm blew in at _exactly_ the worst moment. Since that initial disappointment, my other eclipse trips have (so far) been successful.
I travelled to Hungary to see it, rented a house in a remote village had clear sky the whole week, but had a clouded sky when I took of the the place the eclips was 100% it stayed lightly clouded till short before the eclips, then the clouds broke, we could watch the eclips with the flames around the edges, but it was still to hazy to see the corona. I think the slight drop in temperature around a solar eclips makes the clouds break when it is not too heavy clouded.
13:23 I watched Matt die a little. I sympathize with everyone on that boat. I remember clouds showing up right as the 2017 eclipse reached totality when I went to see it.
I feel that too. I live 45 minutes from where totality was, my dad got a great campsite years in advance at Glendo. They were in the background of many of the mainstream science communicators backdrops. I was having a class in Scotland, and every single news article, blog post and UA-cam video was about the eclipse I didn't see. XD
Did you know the great American total eclipse of the chart was for my birthday ohhh the exact same date, what an achievement and a nice gift for a scientist :)
“The South Pole is just south of here” 😂. That was a really nice explanation Matt! Eclipse going the wrong way. Didn’t know the 23.5deg tilt was large enough for an reverse eclipse phenomenon. Cool to know
I have a feeling it was taking your spouse to Antarctica to watch an eclipse, and there just happened to be some maths topics for the spouse to cover while they were there.
Fun fact: Most modern aircraft have a special polar navigation mode when a flight path takes them near either pole. More specifically, when Boeing comercial aircraft pass above 84 North or below 84 South, they switch to an completely inertial reference system for the flight computer. If they didn't, the computer would likely crash when trying to calculate east to west distances near the singularity of a pole. On top of that, if an autopilot system is waypoint flying over or near the pole exactly, the flight crew has to make sure to aircraft doesn't suddenly try to turn the airplane around when it passes over the pole and east/west flip around. Sometimes i hate how we do navigation, but there probably isn't a better way
That was the way it was done up until the turn of the century, but by the time I went to flight school in 2004 everything had switched to GPS/Glonass/Galileo.
It was really cool when the eclipse track on the virtual globe almost did turn into a straight line when the globe was in the right position. Geometry is pretty wild sometimes. Speaking of drawing lines on planets, the planet Kerbin in Kerbal Space Program has 6 hour days, so each 1-hour time zone is 60 degrees wide. Can you see where this is going? One *minute* of time zone is one *degree* of longitude. Delightfully confusing! XD
That's not confusing at all, that's the sort of delightful consistency I wish we could have more of in our own timekeeping systems! I never realized the parallel, that's amazing!
And it's all because Matt has too much integrity to do clickbaity headlines ! (He knows he *could*...) I trust that he at least sleeps well, without any lies on his tongue to choke on. :)
Great video! Good that you got to travel to this eclipse. I couldn’t go, and it was the first total eclipse I’ve missed since 2013 (I think you and Lucie and I commiserated over lunch at MathsJam the day of that eclipse). You don’t have to go quite as far as Antarctica to see a “wrong direction” eclipse, although I would have loved to have done so. The annular eclipse of May 31st 2003 also went “behind the pole”. I saw that eclipse from just outside Lerwick in the Shetland Islands, although unfortunately I too was interrupted by cloud; I saw the partially eclipse Sun rise above the horizon, then climb into a bank of cloud, in which it stayed throughout the period of annularity. One other feature of the 2003 eclipse was that it crossed a lot more time zones than the 2021 eclipse - starting at local dawn in northern Scotland, heading west across Iceland and Greenland, and concluding the partial phases at sunset in the Aleutian Islands, on the other side of the International Date Line. Which means that the 2003 annular eclipse finished the day before it started.
I know that feeling. I was going to go to Lincoln, Nebraska (closest city to Dallas where I could see it in totality) to see the 2019 eclipse, but someone talked me into going to the beach at the same time, so I went to Charleston, South Carolina. A couple of hours before the eclipse, the clouds rolled in and my view wasn't much better than this, while Lincoln had a clear sky. At least you got to go to Antarctica though.
Lincoln was right at the limit. There were only two large* cloudy places during that eclipse - Charleston, and an area between Lincoln and Kansas City, including the western half of Kansas City. Unfortunately, that's where I live, and I had been waiting for the eclipse for literally half of my life at that time. It was sunny all morning, then a huge thunderstorm rolled in about ten minutes before totality. We got something like six inches of rain in one afternoon and night. *it seems that portions of the Carbondale, IL and Nashville, TN areas were prevented from seeing the eclipse by clouds, but they were scattered clouds in a mostly clear sky
Matt really did hear the ice falling around the 13:01 mark when he says that the Antarctic Circle was getting smaller! Just in frame, on the right-most edge.
The fun math-y/physic-y bit is that it's so far away that you see it fall and the sound takes a few moments to get to Matt. Goes to show just how far away and yet how big those ice sheets are!
I bought your humble pi book on audible today, this very was very well done and I thought it was a good way to show my appreciation and reward myself at the same time...sorry I am selfish. You are getting close to the big 1 million subs hope you are excited.
The magnetic pole you were talking about is actually the Earth's North magnetic pole! That's why the south poles of all compass needles point toward it.
@@cezarcatalin1406 They invented compasses before they figured out magnetism, so it makes sense from that perspective. By the time anyone worked out what was actually going on everybody had already labelled their compasses; it would have been even more confusing to change it.
In magnetism, the pole concept is an approximate scheme to label regions outside a bar magnet where magnetic field lines converge (that's called S) and diverge (that's called N). No matter how you label them, it then follows that opposite poles tend to attract. So whatever you call the end of the compass needle that points roughly toward the geographic south, the magnetic pole that lies in that general direction must be labeled the opposite of that end of the compass needle. It is a matter of logical consistency of the pole concept in magnetism, independent of the arbitrary labeling conventions. The more fundamental issue is that poles are generally a simplistic way to characterize magnetic fields - but if you insist on using them, you have to do it consistently.
tell me...when a substance is heated until it's melting point like metal. it will loose all magnetic properties. can anyone of you explain how the earth has magnetic poles with a molten core?
You went a long way to see an eclipse, bummer that it was cloudy! I live in Rutherford County, North Carolina, and went to Sylva a few years ago. I saw the shadow of the interstices of leaves by the crescent sun, the waves moving on the ground, and all that.
It's also funny that the magnetic pole that is situated in Antarctica is actually the northern magnetic pole. The southern magnetic pole is on the northern hemisphere. I love it how it's weird this way.
Your facial expression that you showed us again at the end of the video was top notch. That is a level of annoyed and disappointed I can feel through the internet. Thank you Matt, I hope you had fun in Antarctica!
A red jacket in Antarctica to explain a mildly interesting concept. If I didn't know better, I would have confused this video for a Tom Scott Amazing Places one!
I learned about most of this stuff back in high school, but it's been long enough and this was presented in a fun way that this was a really pleasant way to spend my morning with Coffee :) Really feels like the old Bill Nye videos from science courses, but with a modern and different frame. Thanks for the video Matt!
Love you Matt! I think it's incredible you went to these lengths... once you said the line, I knew what was coming, but I didn't expect so much from the premise before that (except wonderful teaching!)
Found this video by chance and I love everything about it, the cool science lesson, the comedic angle, the wifu dropping in and out, great job sir, great job!
I scratched my head about that during a trip to Africa one year. After a little thought I realized the difference has to do with which way your feet are pointing when looking to the sky. The Sun and moon and all the planets rarely stray far from the line of the ecliptic, which is the plane of our solar system seen on edge. That plane is generally southward when seen from the northern hemisphere and northward when seen from the southern hemisphere. So, there is a practical tendency to turn your body differently when viewing zodiac objects from the two hemispheres. In the end, since all objects in the night sky rise in the east, you get the strange impression they arise from opposite sides. Much like the Coriolis effect, it's just a quirk arising from a different frame of reference.
Well, the Sun goes through the sky from right to left above the most part of southern hemisphere, of course looking from the Earth towards its equator. That is why clocks invented on the northern hemisphere go... well, clockwise.
My favorite maths related interview question is: "If you walk 1 km south, 1 km west and 1 km north, and end up in the same spot, where are you?". Spoiler: The south pole. There are infinitely many more points on the south pole then on the north. If you start 1 km north of a 1 km circumference, you would walk 1 km south, take a lap around the earth and back to where you started. There are infinitely many of these points alone, but there is more. You could start 1 km north of a 500 m circumference of the earth and take 2 laps around and end up in the same spot. Now there is infinitely many points before you reach the pole where you can start and still get back to where you started. Awesome answer when thinking out side the box
Great video. In your explanations regarding tilts, you might want to include the tilt of the moon’s orbit 5.14°, and how you get an eclipse when the moon travels through the plane of the ecliptic.
I used to live in the arctic. I can tell you that the whole 'light all the time thing' is not quite accurate. Even far south of the arctic circle it is light 24-7 because even when the sun is down you still have twilight. The same issues apply for the 24 hours of dark. It is more accurate to say that above the circle in the winter the sun is below the horizon for 24 consecutive hours or more at some point and in the summer it is above for 24 consecutive hours or more at some point. I was very close to the circle and we had a great deal of debate as to where exactly the line is. Is it where the whole sun is below the horizon on the solstice for 24 hours? Or is it the point that at least part of the sun is below for 24 hours? And does this include the diffraction of the light by the atmosphere which makes it possible to see the sun even though the earth is in the way?
Solar eclipse go backwards? More like "So much for a video without laughter!" I really appreciate Matt's wit, and everything else in these glorious 17 minutes.
I can't believe you actually went to Antarctica just for a video, that's some insane commitment! How cold was it? I found it surprising you didn't freeze without any headcover in a few of these shots.
Almost! Reminds me of many years ago, going to one of the South African eclipses of the time (there were a few years of partial eclipses followed by a full one). My cousin and I decided to go to Musina, in the Limpopo valley, and my brother, his wife, and most of the rest of the people I knew decided to go to Kruger National Park to do a "two-in-one". It was cloudy everywhere on the morning of the eclipse, but on the Musina side of the escarpment, and down in the desert of the Limpopo valley (the muddy grey green Limpopo - but I think it was drought again, so no mud) the clouds cleared about half an hour before the eclipse, and kept clearing throughout. In Kruger they got the view you and your wife got. If you've seen the corona of an eclipse before, you'll know what a difference that made. Still, you saw Antarctica! Wow! Never mind the eclipse; you'll see one of those again if you want. (And if you haven't yet seen the corona, you might want to travel there if the weather forecast is good, next time round.) (My brother and his crowd didn't even see much game, just to make it worse. It was a bit cold. The animals just stayed put and waited for it to warm up again, that day. I saw that with my own eyes, because we drove back through Kruger, instead of going directly back down the main road.)
1:19 I'd be surprised if the south pole would be a bit North from your position.. Actually, would be possible probably, if you're talking about the magnetic poles, right?
Yeah cause magnetic north/south are different from geographic north/south. If you don't specify, it's usually refering to geographic, but that's just an assumption :)
"The south pole is just to the south of here." I love this statement, as it's true in, on, and all around our entire planet, at least up to some indeterminate altitude.
What a shame it got cloudy for the eclipse. I think it is a must watch at least once in your life an eclipse at totality. It is so beautiful and surreal watching the Moon perfectly block the Sun and see the corona with your naked eyes. I highly recommend it if anybody gets a chance!
Goes to Antarctica and makes epically true statements that the South Pole "is to the South" of him - and not at one million subscribers yet. Steve Mould won the contest (now at 400k more) and is playing with string. Matt needs to be more appreciated.
@@calinguga pretty sure he would admit he was wrong if it was proven he was wrong, however the arguements hes got into recently he has been right about, so he has nothing to admit to
Oh boy I finally have a correction for a standupmaths video! At 5:55 it's actually pretty much only Mercury that revolves (nearly) around the axis exactly orthogonal with the orbital plane. Edit: In order of most to least orthogonal: Mercury, Venus, Jupiter, the rest

"Brace for more Antarctic videos." - Yes, I hear the Summers are nice there.
Matt, you want corrections so... in the description it should be "paid" not "payed". Or is this Parker spelling?
I was more wondering where your ship travelled from. New Zealand, Chile, or South Africa. Based on your link, looks like Chile.
Considering that the Moon rotates counterclockwise around the Earth (when seen from Polaris): does the Earth rotate counterclockwise around the Sun? And does the Earth spin counterclockwise around its own axis?
(It is said that Venus rotates "backwards" around its own axis, when compared to the other planets, but no-one says wether the "right" way is clockwise or counterclockwise.)
That's not nearly as expensive as I thought it would be, but still QUITE unaffordable for me.
Imagine travelling thousands of miles just to get the same weather as back home. Truly a Parker Vacation.
That was one Parker Eclipse!
Reminds me of the story of Guillame Legentil.

Super informative. Before seeing Matt’s globe I had no idea there was an enormous circular sea in the middle of Antarctica.
That's a reinforcement patch. It would be whimsical to say that who knew the Earth had a big blue vinyl patch over Antarctica

I was impressed at the coincidence. It is South of *here* too!
But it turns out it could have been magnetically north. Who knew.
actually he would need to go south and then back north to reach the magnetic south pole :D
Technically, the area where you can experience 24h sunlight is slightly larger than the arctic circles, wheras for 24h darkness it's slightly smaller, thanks to atmospheric refraction.
But damn, what a commitment to seeing some expensive clouds :-) Great video!
Also because sunrise and sunset are counted from the top of the sun but the arctic and antarctic circle is based on the center of the sun.
Actually it also depends how tall you are.

@@TrimutiusToo Technically correct: the best kind of correct.
And here, here and here. Also over there, and there, and of course there too.
If you happen to be between geographic and magnetic south, then wouldn’t the South Pole be technically north of you?

Sometimes i hate how we do navigation, but there probably isn't a better way
Rock, rock on!
Does it use stereographic coordinates, choosing the orientation with the singularity at the other pole? Or quaternions
Surely they use GPS these days?
That was the way it was done up until the turn of the century, but by the time I went to flight school in 2004 everything had switched to GPS/Glonass/Galileo.

Matt really did hear the ice falling around the 13:01 mark when he says that the Antarctic Circle was getting smaller!
Just in frame, on the right-most edge.
The fun math-y/physic-y bit is that it's so far away that you see it fall and the sound takes a few moments to get to Matt. Goes to show just how far away and yet how big those ice sheets are!
Spotted it, awesome!
That's what is meteorologically known as a Parker Eclipse
Hey Matt, was fun to spend time with you and Lucie onboard the Amundsen. Thanks for the good memories!
We need more - Professor Lucie Green
YES, Yes, yes! We do!
I bought your humble pi book on audible today, this very was very well done and I thought it was a good way to show my appreciation and reward myself at the same time...sorry I am selfish. You are getting close to the big 1 million subs hope you are excited.
"You're gonna play the role of the Sun. Also not to scale. Should be less bright!" - INSTANT LIKE
"Antarctica is south of here"
"do you have any idea how little that narrows it down?!"
The magnetic pole you were talking about is actually the Earth's North magnetic pole! That's why the south poles of all compass needles point toward it.
I am very concerned about who the hell was in charge of setting these standards.
@@cezarcatalin1406 They invented compasses before they figured out magnetism, so it makes sense from that perspective. By the time anyone worked out what was actually going on everybody had already labelled their compasses; it would have been even more confusing to change it.
In magnetism, the pole concept is an approximate scheme to label regions outside a bar magnet where magnetic field lines converge (that's called S) and diverge (that's called N). No matter how you label them, it then follows that opposite poles tend to attract. So whatever you call the end of the compass needle that points roughly toward the geographic south, the magnetic pole that lies in that general direction must be labeled the opposite of that end of the compass needle. It is a matter of logical consistency of the pole concept in magnetism, independent of the arbitrary labeling conventions. The more fundamental issue is that poles are generally a simplistic way to characterize magnetic fields - but if you insist on using them, you have to do it consistently.
tell me...when a substance is heated until it's melting point like metal. it will loose all magnetic properties. can anyone of you explain how the earth has magnetic poles with a molten core?
You went a long way to see an eclipse, bummer that it was cloudy! I live in Rutherford County, North Carolina, and went to Sylva a few years ago. I saw the shadow of the interstices of leaves by the crescent sun, the waves moving on the ground, and all that.
It's also funny that the magnetic pole that is situated in Antarctica is actually the northern magnetic pole. The southern magnetic pole is on the northern hemisphere. I love it how it's weird this way.
I don't believe you
Your facial expression that you showed us again at the end of the video was top notch. That is a level of annoyed and disappointed I can feel through the internet. Thank you Matt, I hope you had fun in Antarctica!
My mum may have played a role in ome of those treaties Matt! As one of the leaders of the Greenpeace campaign to make Antarctica into a 'World Park'
1:25 "The south pole is just to the south of here.." LOL True for literally EVERY point on the earth's surface.
A red jacket in Antarctica to explain a mildly interesting concept. If I didn't know better, I would have confused this video for a Tom Scott Amazing Places one!
Everybody on the boat gets a red jacket. They're really good!
So glad to see the return of “unfortunately, it’s not that simple”
I wonder he just wanted to go to Antarctica, and realised he could write it off as a business expense
I learned about most of this stuff back in high school, but it's been long enough and this was presented in a fun way that this was a really pleasant way to spend my morning with Coffee :)
Really feels like the old Bill Nye videos from science courses, but with a modern and different frame. Thanks for the video Matt!
"you will play the role of the sun"
Also not to scale...
Should be smaller
Love you Matt! I think it's incredible you went to these lengths... once you said the line, I knew what was coming, but I didn't expect so much from the premise before that (except wonderful teaching!)
I’d say I’d like to see the flat earthers try to explain it, but I’ve seen what they consider ‘explanations’.

"so I'm using the sun as the sun" , good job there Matt, no need to reinvent the wheel.
Oh! The disappointment on Matt's face! Awesome video!
Matt Parker and the art of giving things a go
Found this video by chance and I love everything about it, the cool science lesson, the comedic angle, the wifu dropping in and out, great job sir, great job!
It's never occurred to me before that the sun goes through the sky from right to left in (geometrically non-trivial parts of) the southern hemisphere.
I scratched my head about that during a trip to Africa one year. After a little thought I realized the difference has to do with which way your feet are pointing when looking to the sky. The Sun and moon and all the planets rarely stray far from the line of the ecliptic, which is the plane of our solar system seen on edge. That plane is generally southward when seen from the northern hemisphere and northward when seen from the southern hemisphere. So, there is a practical tendency to turn your body differently when viewing zodiac objects from the two hemispheres. In the end, since all objects in the night sky rise in the east, you get the strange impression they arise from opposite sides. Much like the Coriolis effect, it's just a quirk arising from a different frame of reference.
And the moon is upside down
Well, the Sun goes through the sky from right to left above the most part of southern hemisphere, of course looking from the Earth towards its equator. That is why clocks invented on the northern hemisphere go... well, clockwise.
"The south pole is just south of here"
"I'm using the sun as the sun"
You truly have a way with words.
Need more Professor Lucy Green cameos!
14:20. I finally get it. He put the "eclipse viewer" in front of his eyes so he could view it. LMAO🤣🤣
My man out here in the cold just to teach us some maths. Legend.
Somebody get that man a Rhombic DodecaHAT-dron
My favorite maths related interview question is: "If you walk 1 km south, 1 km west and 1 km north, and end up in the same spot, where are you?". Spoiler: The south pole. There are infinitely many more points on the south pole then on the north. If you start 1 km north of a 1 km circumference, you would walk 1 km south, take a lap around the earth and back to where you started. There are infinitely many of these points alone, but there is more. You could start 1 km north of a 500 m circumference of the earth and take 2 laps around and end up in the same spot. Now there is infinitely many points before you reach the pole where you can start and still get back to where you started. Awesome answer when thinking out side the box
When you said "Spoiler: The south pole", did you mean it as an answer to the question? Because it should be the north pole.
"The South pole is just to the South of here". This sentence applies to everywhere in Antarctica. 😂
it applies to everywhere
Except the South pole itself!
@@DemirSezer
As long as "just" doesn't mean "slightly", which is what it usually means in this construction.
I don't know why but "I'm using the sun *as* the sun" broke me. Too good
The latitude of the Antarctic Circle is 66.5 degrees south, which is just 90 - 23.5
Great video. In your explanations regarding tilts, you might want to include the tilt of the moon’s orbit 5.14°, and how you get an eclipse when the moon travels through the plane of the ecliptic.
I used to live in the arctic. I can tell you that the whole 'light all the time thing' is not quite accurate. Even far south of the arctic circle it is light 24-7 because even when the sun is down you still have twilight. The same issues apply for the 24 hours of dark. It is more accurate to say that above the circle in the winter the sun is below the horizon for 24 consecutive hours or more at some point and in the summer it is above for 24 consecutive hours or more at some point. I was very close to the circle and we had a great deal of debate as to where exactly the line is. Is it where the whole sun is below the horizon on the solstice for 24 hours? Or is it the point that at least part of the sun is below for 24 hours? And does this include the diffraction of the light by the atmosphere which makes it possible to see the sun even though the earth is in the way?
OMG... Matt's face @ 13:40 I'm dying...
... thanks for the laugh, I hope your vacation was good otherwise.
I mean, that was still pretty cool, haha. I think it helps if you've seen an actual total solar eclipse before.
Solar eclipse go backwards? More like "So much for a video without laughter!" I really appreciate Matt's wit, and everything else in these glorious 17 minutes.
I can't believe you actually went to Antarctica just for a video, that's some insane commitment! How cold was it? I found it surprising you didn't freeze without any headcover in a few of these shots.
it is nearly easter at the moment in antartica
@@assalane sorry, I'm not Christian, at what season does Easter usually occur?
@@smorcrux426 Spring (in the northern hemisphere).
@@smorcrux426: Hehe, the scheduling for Easter is actually based on how the moon orbits the earth relative to the sun...

English is not my first language. I meant summer
Almost! Reminds me of many years ago, going to one of the South African eclipses of the time (there were a few years of partial eclipses followed by a full one). My cousin and I decided to go to Musina, in the Limpopo valley, and my brother, his wife, and most of the rest of the people I knew decided to go to Kruger National Park to do a "two-in-one".
It was cloudy everywhere on the morning of the eclipse, but on the Musina side of the escarpment, and down in the desert of the Limpopo valley (the muddy grey green Limpopo - but I think it was drought again, so no mud) the clouds cleared about half an hour before the eclipse, and kept clearing throughout. In Kruger they got the view you and your wife got.
If you've seen the corona of an eclipse before, you'll know what a difference that made.
Still, you saw Antarctica! Wow! Never mind the eclipse; you'll see one of those again if you want. (And if you haven't yet seen the corona, you might want to travel there if the weather forecast is good, next time round.)
(My brother and his crowd didn't even see much game, just to make it worse. It was a bit cold. The animals just stayed put and waited for it to warm up again, that day. I saw that with my own eyes, because we drove back through Kruger, instead of going directly back down the main road.)
1:19 I'd be surprised if the south pole would be a bit North from your position..
Actually, would be possible probably, if you're talking about the magnetic poles, right?
Yeah cause magnetic north/south are different from geographic north/south. If you don't specify, it's usually refering to geographic, but that's just an assumption :)
Hahaha, I see he mentioned it himself later too...
11:49 "Unfortunately, it's not that simple."
*Captain America:* I understood that reference!
I am shocked you didn't discuss the issue of to what extent the Earth is actually an oblate spheroid.
It's something like a third of a % so not a huge difference
But it's prime Matt Parker material... 👍
@@stevemonkey6666 That's true yeah! Sorry I just got the impression of the comment implying it was a big difference 😅
It's a Parker sphere!

Man!! I jumped on my chair when i saw the Antartica!!! I'd love to go there in the future!!!
I'd love to go there in the past
If the eclipse went over head when you were standing at the south pole, would the eclipse go from north to north?
... please don't make me question the reality of arbitrary systems anymore than I am already...
It stays north!
grumpy Matt with a 5 o'clock shadow might be my favorite ever. excellent gif/memeing potential
"The south pole is just to the south of here." I love this statement, as it's true in, on, and all around our entire planet, at least up to some indeterminate altitude.
What a shame it got cloudy for the eclipse. I think it is a must watch at least once in your life an eclipse at totality. It is so beautiful and surreal watching the Moon perfectly block the Sun and see the corona with your naked eyes. I highly recommend it if anybody gets a chance!
Yes, I can also highly recommend it. I watched it 1999 here in Europe.
Goes to Antarctica and makes epically true statements that the South Pole "is to the South" of him - and not at one million subscribers yet. Steve Mould won the contest (now at 400k more) and is playing with string. Matt needs to be more appreciated.
playing with string, getting into arguments, and not being able to admit he's wrong
he's basically me.
Matt's content is much less vulgarized, It's an unfortunate byproduct, but the humor remains on an untouchable level.
@@calinguga pretty sure he would admit he was wrong if it was proven he was wrong, however the arguements hes got into recently he has been right about, so he has nothing to admit to
Disappointed Matt's face is just the best depiction of that emotion.
Oh boy I finally have a correction for a standupmaths video!
At 5:55 it's actually pretty much only Mercury that revolves (nearly) around the axis exactly orthogonal with the orbital plane.
Edit: In order of most to least orthogonal: Mercury, Venus, Jupiter, the rest
Aaah... A Parker video!
"The south pole is just to the south from here!" Amazing!
