If I could turn back time


This is what I’d see.

    The Mollweide projection is my favourite, but they really ought to have let the globe rotate in the latter half of the film, to avoid the distortions around the edge.

    What was the music?

    Remember, if you could turn back time, you’d see Godzilla re-assemble Toyko from shattered ruins, wave off all the army and helicopter guys that were hovering around trying to help, then back slowly into the ocean and leave.

    Arvo Part – Fratres.

    I don’t think so. I ran it by Shazam, which recognized it as another piece that has been sampled into another piece that’s on youtube. I’m listening to Fratres right now and I don’t think that’s it.

    Marcus, the same piece, performed by different players, can sound very different. For instance, I listened to two performances of Prokofiev’s “Alexander Nevsky” suite yesterday. The Thomas Schippers version, even though recorded back in the early 60s, sounded much better (to me) than a more modern rendition.

    Anyway, the piece in question sure sounded like an Arvo Part work to me.

    I don’t know about this particular version, but it’s Pachelbel’s Canon all over again.

    Just watched, and yep, it’s Pachelbel’s Canon, absolutely. Much like Vivaldi’s Four Seasons, seriously over-used, but they both endure as beautiful pieces of music.

    I suspect they left the Great Lakes in for reference but they were only formed 20,000 years ago.

    I like these kinds animations and have seen a few I will be following the links for sure.
    A new thought or question occurred to me as I watched the continents drift around and the seas change. What were the weather patterns, ocean currents., and climate like with the changing distribution of land ? uncle frogy

    Caine, I disagree. Please listen to Pachelbel’s Canon, then the track on the video, then Part’s Fratres.

    Also, Pachelbel’s Canon is, as its name suggests, a canon, whereas the music on the track isn’t (to my ears, anyway).

    It’s neither. The bass ostinato is C-G-A-F at the beginning … and it’s all extremely simple, which doesn’t get us very far. It’s not D-A-B-F# as in Pachelbel. If the F were an E, the line went down to G rather than up, and a bunch more things happened differently after the first four notes, then we’d be talking…. But very very little of it is actually a match or else derived from it in some simple way. There’s also no obvious canonic imitation that I noticed, but perhaps a lot could be found hiding under the surface if I started digging, for what that’s worth. (The point is, “being a canon” isn’t really what’s required here… check Rochberg’s string quartet no. 6 mvt. 3, for instance, which is a set of quasi-Romantic variations on that theme and not much is strictly speaking canonic — yet despite the overall structural differences, which are pretty significant, you can easily tell where the material in it came from.) Whatever the case may be, it isn’t from Pachelbel or clearly derived from it, and we probably all agree he gets plenty of credit for his actual work as it is. Since I don’t get credited for things that seem sort of vaguely similar to something I made so long as you’re not paying much attention, neither does he.

    And the Pärt piece… well, I really can’t imagine how anyone could’ve heard any of that in the video. Are you sure you’re not thinking of something else? At first, it reminded me a little bit of Hans Zimmer’s main theme for the movie Inception (maybe lots of other movies he’s done too), but nope, definitely not that either.

    You might think that, with all of the numbers which have been jammed into the intertubes over the past couple of decades, we’d be able to get info like this easily and decisively, but we’re not there yet.

    The best I’ve got is that probably somebody wrote it within the last three or four hundred years, and very recently four people played it or something like it. That doesn’t narrow it down much. So… I think we’re out of luck, unless somebody comes along who was already familiar with it.

    Caine:

    Woah. Thank you for that!

    Heh, it is a really beautiful piece of music … probably should’ve mentioned that. And transformative like Rachmaninoff’s Rhapsody on a Theme of Paganini, although I guess the transformations are lot more subtle.

    It would so much better hearing that all of the time, instead of the boring old original, no? He just needed better handwriting, frankly. ;)

    Poor Antarctica. Both it and its ecosystems just got screwed over completely by continental drift, as Australia was pulled away, Antarctica pushed south over the South Pole, and then the latter isolated from any warmth by cold circumpolar ocean currents. I’ve often wondered if maybe some non-avian dinosaurs survived down there after the K-T Boundary, already adapted to colder temperatures and darkness, only to be wiped out as the continent froze over and then was covered in thick ice sheets.

    India’s migration is pretty awesome. It spent tens of millions of years as a separate continent amidst what became the Indian Ocean, slowly migrating northward. Can you imagine what happened to its flora and fauna during that time, when it was separated from the other land masses by hundreds or even thousands of kilometers of ocean? It probably had some neat endemic species that got wiped out when the connection to Asia happened, like what happened to some of South America’s animal species when it was connected to North America.

    Oh, that was very cool. Thank you again!

    Heh. I listen to a fair amount of neoclassical metal, and I’ve always been amused by all the people who think “the old dudes” were the headbangers of their day.

    I’ve followed the link to socialmedianews.me, but after poking around at that site I can’t find anything relevant.

    sounds like there’s a story behind that.

    I just realized… you’re far older than I thought!

    All the black lines are for reference; the colors indicate where the land and water boundaries would’ve been at the time.
