      East was focal for ancients as they were before magnets and hadn't explored far enough to see the sun or moon trace a full circle. Today we use north as our focus as we understand two points on a planet remain stationary throughout its rotation; the north and south poles. Which would have been called "sinister" and "solar" by the ancients. Funny stuff.

    " the south magnetic pole is actually near the geographic North Pole, as opposites attract. "
    Or something like that.

    This is a very well-done video. The narration and information presented his pre-quality. However, if you're looking for the topic of the title, true North versus magnetic north, you can skip ahead to about five minutes. Prior to this is some interesting history that's not really related to the stated topic.

    I find it astonishing that such simple concepts, like "True" north verses "Magnetic" north need to be explained to "Educated" adults!
    These are things I learned in school, by the 3rd or 4th grade!
    But this was way back in the 1950's when Children actually got a vastly better "Education" then is offered today!
    Also, if you were in the Boy Scouts in the 60's, it one of the VERY FIRST principles you learned!
    Cheers!

  • @faramund9865
    @faramund9865 2 года назад +2

    The etymology of east is certainly right, for north it is up for debate as far as I know.
    Either way I love that you're using etymology to explain meaning behind these concepts and show people they are not just hollow sounds.

  • @KTFG

  • @Xeno_Bardock
    @Xeno_Bardock 5 лет назад +8

    Magnetic north and south poles are not actually a point but a magnetic huge circle located at 80 latitude parallel. Its where magnetic field lines go in and out of earth creating a huge magnetic circle. If a person goes inside this magnetic circle, compass will go haywire.

    1:40 Don't do that pointing with a single arm to your left or right, you will most probably pivot your shoulder without being aware of it and thus pointing too much left or right of the real North/South. Always spread out *both arms* to the left *and* right in a most perfect straight line possible and then align both straight arms with the sun in the most accurate 90° angle (watch at your shadow being perfectly lined up behind you as well). Then turn only your head to the left (or right) and aim using either arm to find at least two waypoints in alignment with one of your arms. This way you make sure your shoulder and hence also your arm is not unwittingly pivoted and misdirecting you.

  • @bixbybixby
    @bixbybixby 8 лет назад +1

    Good video. The bottom line is the vital necessity of at least ONE reference point by which other things can align to. In this case, the stable reference point is a magnetic needle points to magnetic north. Even though it changes slightly it can still be used as a stable reference point if you know the rate of amount of change annually etc. Which is printed on maps for your edification.
    When people get lost they are lacking even a single reference point.

  • @geezerdombroadcast
    @geezerdombroadcast 7 лет назад +1

    Freaking outstanding job ! I find it difficult to understand why young people, especially, and everyone really, isn't enamored with understanding maps, and compasses. When I went to geography, or history class as a boy to see the beautiful pull down maps my mind slipped instantly into adventure dreamland. I was with Admiral Perry, or Shackleton, or Lewis, and Clarke, or Magellan. It was fantasy land heaven for me. I learned more by age twelve than most people will ever know. That's tragic for our society. There is a universe of knowledge associated with learning about navigation. Geometry, calculus, vector analysis, geography, history, nautical language, law, politics, astronomy, it just goes on, and on. Every teacher should master it, because it encompasses so many subjects. Perhaps someone should teach the orangutan in the White House how to read a map, and compass, so he can find North Korea on a map without GPS, and someone to hold his hand.

      i started learning how to read a map and which country borders which, currently know europe, learning asia now. i know over 120 country names with their capitals that i can say without writing down. i'm always trying to learn new things. reading philosophy books, history books & always questioning everything. knowledge is so empowering and humbling at the same time.

    • @geezerdombroadcast
      @geezerdombroadcast 7 лет назад

      Please run for President. You're what we need, not an illiterate fascist clown like we have now, that couldn't find North Korea, or Syria on a map if you stuck a pin flag in it for him. Keep it up. You'll have an exciting life. "I promise", especially when you start actually visiting all those places in the map of your mind. Have fun. I've been doing it for 50 years now, and had a ball Thailand, and the Andaman sea, to Amsterdam, Mexico, Paris, the Philippines, Hong Kong, London, and a whole bunch more to see if I live long enough. Don't wait to long.

    The last photo is interesting. The sun is in the south which means it's around noon and it means the photo was taken in the northern hemisphere. Judging by the snow on the ground and how low the sun is, it's probably December or January.

  • @allenheart582
    @allenheart582 2 года назад

    Because of the coming micronova, declination is moving much farther, and much faster and so declination information is likely incorrect My up-to-date declination is 30 degrees, 15 degrees off from the official declination for my area. but there is still a way to recalibrate magnetic declination using the shadow of sticks recording the path of the sun---rotation of the earth has not yet changed. First stick will show East. Mark it with a sharp stick pushed in. After a few minutes you can mark sun shadow travel where the shadow has moved - Push another stick in to mark West. Lay a straight stick from the E mark to the W mark. Geographic north or True North is 90 degrees from the E-W line. With your compass pointing toward True North, note how far off your compass is now. That is your true up-to-date declination. More on micronova in my 2nd book, Surviving the Micronova: This Train Is on the Tracks will be available in September 2022.

    Don't expect to get a standard magnet to attract an American nickel as well as seen here. I placed a nickel on top of several fairly strong magnets and it took several years for the magnet to have any affect on the nickel. I realize this is likely because of the lack of nickel in the coin but still I was a little disappointed at the time.
