      CrashCourse (*Heavy breathing*) I've been acknowledged by a Crash Course Member (*Heaving breathing*).
      But seriously though it's a really well made intro. The ONLY thing I would like to change is the timing of the scene shifts so that they match the jingle of the theme. Other than the logo to the "telescope" scene, all the other shifts don't match the "DANANANA" of the song.

    • @crashcourse
      @crashcourse  9 ปีที่แล้ว +17

      Logan Podojil The quote certainly sells it! I also love that it's a very on-theme spin on the song. I was/am equally blown away by *****'s work :)

      sara meachel It's because school isn't there for you to learn. It's there to teach you how to be a good blindly obedient robot.
      Sit down, shut up, raise your hand to pee, sit down shut up, stand in line, sit down shut up.
      It's based on the Prussian model of public education wherein good soldiers and good tax slave working robots are to be manufactured.
      The government cracks down and regulates home schooling and private schooling because they don't wish for there to be places of education where you can be entirely free of propaganda.
      They, in effect, have a monopoly, and it is very, very, very effective.

    • @hornchief4839
      @hornchief4839 9 ปีที่แล้ว +16

      WTF are you talking about? The educational system is bad here because of so many kids. They have to spit out as much info as they can without confusing them by going so fast. That's why private schools are good, because they're schedule is based on the child's ability to learn.

      Just in case this wasn't ironic. Have you ever done analogies? A is to B as C is to D. (denoted A:B :: C:D) They should have been on every standardized assessment you took. So Here's the simplest way of understanding it
      The Sun : A Star :: Broadway :: A Street
      Earth :: A Planet :: Mona Lisa :: A Painting
      So, yes, the Earth is a Planet and the Sun is a Star. One is the name of a specific one (though sometime a sun is algo genericized to reference a star with planets, but lets not overthink it). The Sun and Earth are ours. Earth or Eorthe (Old English), Jorth (Old Norse), Ertha (Old High German) used to just mean Land. The Sun was Sunne/Sunno/Sunna (same order I posted for Earth). They are just names. Not Ah-ha moments.

    This is not a course about Astronomy, the is a course about everything!
    In ~10 mins you made me search for:
    (i) chemistry Fe, N, Ni, Ar, Ozone: why they are the most ingredient of the earth?
    (ii) the magnetic field of the earth: How it is created? and why it's close form the sun side and open the other side?
    (iii) Geology Plates tectonics: how they were first formed? and what laws describe their movement?
    (iv) Climate change: I am very informed about this subject, nevertheless you got me thinking about de-Terraforming, or is it Terradeforming? ;)
    (v) and most important, the link between them, as I already had a school (basic, dispersed) knowledge about them.
    Seriously, bad astronomer, crash course, you're awesome!
    I am going directly to patreon to double my pledge, you really deserve more :)

      Diana Peña The Greek philosophers didn't build Athens physically but they built its soul. The Acropolis may disappear one day but the thoughts of Aristotle lingers on ad infinitum.
      What is useful? Building stuff? Bankers playing with immaterial investment bonds? The Germanic tribes were more physically "useful" when they focused on the military than "airhead talk", but they sank western civilisation backwards by at least a millennium.
      Is your toaster "useful" because it makes toasts, therefore tangibly more important to life compared to philosophy? The material is "useful" in its lifespan, after which it's gone and prune to history repeating itself. The immaterial is useless in the short term, but invaluable to the building of other immaterial things like, oh I don't know, CIVILISATION?

      @Ryan-wk3mc 8 ปีที่แล้ว +7

      +Kira Burns The water on Mars is kind of liquid. It's not liquid water like we have on earth. Water on earth flows freely, the water on Mars flows through different salts. Mars is much too cold and the atmosphere much too thin to have free-flowing water.
      To get an idea of what this looks like, try to imagine a thin layer of table salt on a dinner plate. Now add a couple or a few drops of water. Over the course of a few seconds, the water spreads out to form a homogeneous average wetness throughout the layer of salt (assuming there's enough water). This same principle is what we've discovered happening on Mars, except that it flows north and south through salt deposits over the course of seasons. The force that powers this water migration is, I believe, temperature. During the warmer parts of Mars' seasonal cycle, the water flows towards its equator, and towards the poles during the colder parts of the seasonal cycle. It may be the opposite flow pattern, I haven't read anything about it in a while so my memory is a little foggy on this part.

    I love reading and following Phil Plait on Twitter, Facebook, Slate, and especially CrashCourse. I love reading the subject matter and I love how he puts scientific smarty pants things in terms that normal everyday dumb people can understand.
    I have to say though, reading some of his opinions on Twitter, and Slate seem kinda troll-y and almost invite attacks - such as "Stick to Astronomy." This is why I love CrashCourse. It is still him talking, but you can hear his tone, and his matter of fact style. It is definitely not troll-y, or inviting criticisms. His voice and tone kinda puts a different feel to the rest of his words online.
    I think CrashCourse is a good thing for normal everyday dumb people who have trouble avoiding arguments over things they aren't formally educated in.

      Disciple Demon The earth's electromagnetic field generated by the counter rotating liquid iron core of the earth will disappear and the solar wind will no longer be kept at bay and our atmosphere will be slowly blown away into space. Earth will end up just as Mars is today.

    Another great episode. :) I've read in a couple books, including "Rough-Hewn Land," by Keith Heyer Meldahl, that the motion of Earth's tectonic plates is due to the pull of the edges of those plates as they're subducted under adjacent plates and sink into the mantle, rather than to mantle convection.

      +KSI FlapJaksLol Xenoforming perhaps. That is shaping into something alien. Venuforming could be used as a more specific name. Shaping into Venus. From another perspective, Terradeforming, distorting away from Earth; though that one is pretty awkward sounding.

    • @brodysbuckinbroncos7697
      @brodysbuckinbroncos7697 8 ปีที่แล้ว

      TonboIV I meant a term to describe the return of planetary normalcy before human intervention, but that's pretty good. I like the specificity of Venaumorph. For example, say Mars was colonized and then terraformed. The resources on Mars are spent after millenia, and humanity leaves it to return to its natural state; or directly affected negatively by humanity after it has been terraformed (war on a planet wide scale), then the carnage results in said return to normalcy.
