    When you spoke about light pollution I remembered when I heard about when there was a blackout in a big city and all the lights went out, the police station kept getting calls from people freaking out about the "big colorful streak in the sky".
    It was the milky way.

      I'm not surprised. By now at least 95% of humans not only keep their heads down to the ground but burying their faces in their electronic toys. That's probably they're afraid to look up. The sense of wonder is fading away for some.

    We should have a national holiday where, for one night, cities turn off most of their lights, enough to ward off the light pollution, but still keep things operational.

    I went to Death Valley, CA this week, which is known for the best place to see the Milky Way here in southern California...I screwed myself over by not checking the Moon Phase and it turned out it was a full moon on the night I was there. The moon was SO bright we couldn't see the Milky Way as bright as we'd hoped. Anyone thinking of star gazing, check your moon!

    When I grow up (I'm 14 now) I want to be an Astronomer, my friends laugh at me and say that it's not a real job, and that I will not amount to anything if I try to follow this dream, idk why I'm posting this but if you also have this dream don't give it up because your so called friends say it's stupid, Astronomers play an important role in today's society, so get out there and achieve your dreams, as I want to achieve mine!

      @lynakiyama4909 9 лет назад +91

      I completely agree, I'm currently 13 and my dream is to become one too. I feel like the future of humanity depends on it. Astronomy is so unique and different from most fields because you study something that is unknown. I really hope that I get my dream job, it's not even about the money or whatnot, for me it's the passion and just knowing something that is truly beautiful and amazing.

I was literally putting my face in the screen. It took me 13 and a half years to finally figure out what I really wanted to do. I wanted to become an Astronomer.

      Look for mountains in arid regions. Drier, thinner air helps, and nobody wants to live on a mountain in the desert. That why so many observatories are in Chile; the Atacama desert has high mountains and is the driest place on Earth.

      Well, one, teachers don't exactly have lots of chances when it comes to outakes. Teachers also have to keep a group of people under control. Teachers aren't exactly entertainers, for example, teachers can sound boring as they have to work almost 12 hours a day, prepping work and activities. Finally, a teacher can't really talk at you for 50 minutes, both you and the teacher will get bored.

    • @enigmace9787

      That might mean that either you learn well from crash course, or that your school doesn't teach you well. Or both.

  • @Sta73aha
    @Sta73aha 10 лет назад +149

    This was so interesting! Light pollution really does suck - I grew up in NYC, so I basically never saw a single star. In my late teens I'm living in NJ and on a good night I see only a couple of stars (like maybe 5). It fascinates me that people live in places where they can look up and see that many stars every (clear) night. Hopefully one day I'll experience that in person :)

    • @ChipCheezey
      @ChipCheezey 10 лет назад +8

      That was crazy to me too. I knew that people in more rural areas saw more stars in the sky but I always thought it was to do with how much light at that time and not a long term thing or even the extent it was hindering our view of the sky. Being from Vegas where Paradise has what are probably thousands of lights going up into the sky, the difference is huge.

      @Qladstone 8 лет назад +7

      Katie that's not what Reema meant. Reema meant that if you're interested in space you don't necessarily have to be an astronaut to make space part of your career. You can be an engineer, a computer scientist, a biologist, a economist, a business person - anything - and still pursue a career in space; especially given how a good number of private companies have emerged in the space industry.
      We will need all sorts of expertise - engineers to implement technologies to get us into space, around space and build facilities in space, biologists to examine the growth of crops/animals in space, psychologists to study the effects of space on human behaviour, economists to incorporate the space economy into the traditional Earth macroeconomy, lawyers to work on the new legal challenges that space will bring... etc. You get the idea. Stay open!

You can't see your hand in front of your face. You can see the sky the way our ancestors saw it. The nights when the ocean was calm and reflected the sky are the nights I will never forget.

    The main disadvantage of living north of the Arctic circle is that I never get to see the summer constellations, but on the flip side, I do get to see the winter stars pretty much as much as I want. (Also, when I lived in a larger town for a while, I did notice that the sky appeared darker because of all the light pollution, and that I struggled to find a lot of the familiar constellations I'm used to seeing here.)

    In the civilization(s) that noted the constellation as a Bear with a long tail...Maybe there WAS a bear species with a long tail then and they've since died out (likely killed off by humans)? Though there would likely be some evidence of this somewhere and I've never heard of a long-tailed bear.
    Just a thought.

    @MrThepatrickshow 10 лет назад +29

    This is why I sometimes think the, 'crash course,' approach has drawbacks. All this information about naked eye observation was correct, BUT, I have two problems.
    1) The presentation failed to stress certain in order of avoid confusion. For example, he said that at the North POLE you'll never see stars in the southern hemisphere. But zero of the viewers live at the North Pole, and because it went by so fast, with no special stress, I'll bet many came away thinking he said, that in the northern Hemisphere, nobody sees stars from the southern celestial hemisphere... which is totally not true. Depending on your latitude, you DO see stars from the opposite hemisphere at different times of year.
    And this leads to my second problem...
    2) Because this is a, 'crash course," the subject of naked eye astronomy will never be visited again. This means that the above example of north south dynamics will never be touched on again... which is a shame. Because THAT'S where all the confusion lies for people, and THAT'S the stuff teachers never explain, leading to generation after generation of people who end up not caring because it all seems too confusing.
    Another example: He mentioned that Polaris never appears to move all night long. We've heard that before. What he failed to mention was that Polaris never appears to move (from whatever latitude you're observing from) all YEAR long.
    And that would've been a great starting point to explaining why at certain times of year we see different constellations at night... because we're in different parts off our orbit, which means different parts of the sky are blotted out by the sun each day, and revealed each night... DUE TO THE FACT that Polaris can never move... because, angular momentum.
    That would've been educational. Instead, this was just regurgitating stuff that has been taught since forever and will never lead to anything but the same confusion among the public.

      @inanimatecarbon 10 лет назад +9

      To your point 1, I think there was some stress given to it, but I would have liked if Phil had said something like "and if you live somewhere in between, you see something in between." But to the second point, I think you need to give the show some benefit of the doubt here. They haven't touched on the seasons yet. The episode was mostly focusing on what you could see in the sky in one night, and it would be a little out of place to just throw the seasons in there. I think in future episodes (maybe the next?) they'll get to the seasons and the axial tilt of the earth, and that Polaris doesn't appear to move, AND the precession of the Earth, and how Polaris really does appear to move in the sky over very long periods of time.

      From what I've seen of other Crash Courses on this channel, they do refer to previous material; I think John even mentioned something from CC World History in CC World History 2. It may not be the case in this series since it's a different host, but we should give them the benefit of the doubt.

    • @thevirtualjim
      @thevirtualjim 10 лет назад +14

      I think your point 1 is kind of a stretch. You are assuming you know what others will think they hear/understand. For example, it never entered my mind to conflate the north pole with the northern hemisphere.
      As to point 2, you are assuming you know what the rest of this series will be about/talk about.
      It is true that these crash courses can't touch on everything...hence 'crash course'. Its to get you interested and maybe go and learn more.

    Thank you very much for making this video, Phil. I though it was really interesting to learn about how stars appear to be moving on the sky and in which patterns they move. I live pretty far North.
    I live in Sweden a bit south of Stockholm but the terrible thing is that I live in a city, although it’s pretty small compared to bigger cities in the world like London, New York and New Dehli (in Norrköping, there are only ca. 140 000 people) light pollution is a BIG problem. I can barely see _any_ stars at night and it really pisses me off. This is probably the worst thing with living in the city, although the street carts here are pretty good...

    • @robert_wigh
      @robert_wigh 8 лет назад +1

      ***** Well, I guess I should be considered lucky. According to _Wikipedia_ (goo.gl/3MxfUZ), the population density of the Netherlands is the 31 highest in the world but Sweden has one of the lowest, being in the 197th place in the table. Sometimes, one wishes that one lived in Suriname: it has one of the lowest population densities in the world and lies very near the equator. This makes it the perfect spot for star gazing, you don’t have to worry about light pollution and you can see both the ‘North’ stars and the ‘South’ stars. It could also be a good place for you to visit since you already speak the language: Dutch. (goo.gl/BFKjbc)

    • @robert_wigh
      @robert_wigh 8 лет назад +1

      *****
      Yes, Greenland maybe, or Iceland! Greenland is very cold whilst Iceland is a little bit warmer. Now that I think about it, it’s probably better to go to a country that is really far North or really far South on the globe, like Iceland or Australia, in order to see the Northern or Southern lights.
      The family of a friend of mine lives in a cottage 42 km from town, on the countryside. Honestly I don’t visit him that often nowadays but when I visit him and when we stay late, the sky is beautiful! You can see very many stars, if not all of them. It was there I first discovered that the stars in the sky move though the night.

    • @robert_wigh
      @robert_wigh 8 лет назад +1

      ***** Actually, I have never been to Iceland but I really would like to! The nature! The skies, the language! The music! Oh, I love it all (except for the former prime minister that stole money from the people but that’s a story for another time). After finishing learning Russian and German (in a few years), I plan to learn Icelandic and when after I graduate from a university (maybe in 2026 at the latest), I plan to move to Iceland or at least take a LONG vacation there. I imagine spending the nights studying the stars and the days studying Icelandic.
      I am 14 years old now and I want to work with theoretical physics when I get a little bit older, I think it will be astrophysics or cosmology. I am also very interested in linguistics, the study of languages, so learning different language will be my hobby.
      Yeah, that is what I plan to do in the future. If you don’t mind me asking, how do you imagine astronomy or any astro- subject being a part of your future life?

      terralynn9
      Thanks for the answer. Maybe it's just the crappy laptop speakers I'm using here but I don't hear the fifth note. Or better, I don't hear the fourth note. I just hear a whole tone upwards, a major third down and then a perfect fourth down. But if there was an octave drop in between, that would make the last tone a perfect fifth upwards which is indeed the sequence from Close Encounters.

    • @unvergebeneid
      @unvergebeneid 10 лет назад +1

      I just had a look at the spectrum. I'm pretty certain there is no octave in the melody. It's D6 E6 C6 G5 where it should be D6 E6 C6 _C5_ G5. However, It _is_ the same tone so maybe Thought Bubble felt like they could simplify the sequence in that way. Either way, I find it really interesting that you heard that because to me it sounds and feels really different without the octave drop, even though I can totally see how one could argue that it's the same melody.
      Fun fact, at different times in the movie they play two transposed sequences: G A F F C and B♭ C A♭ A♭ E♭ (www.imdb.com/title/tt0075860/trivia?item=tr0659211).

    The thought bubble at 4:40 mentions the dark ages as being not very scientific and takes a dig at Christianity with the cartoon. The caricature of the dark ages being an era of intellectual or scientific oppression at the hands of the church has been thoroughly debunked by historians. It's crap and I expect more out of crash course. The dark ages are called so because of the lack of surviving art and writings that would otherwise help us understand what society was like at that time. On the contrary what we little we do have was in fact preserved by the church. Furthermore many historians seem to think that the church probably helped provide what little cohesion Europe had at that time. The fact that this little dig made it into an astronomy video, coupled with recent remarks by Neil Tyson deGrasse, makes me think that the field of astronomy is the flagship of the church bashing trend in science. If you're going to church bash at least get your facts straight.
