    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.)

      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.)

      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.

    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.

    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.

      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.

    • @noeckel
      @noeckel 3 роки тому +1

      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.

    • @spelunkerd
      @spelunkerd 3 роки тому +2

      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.

    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

    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?

    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.)
