  • And it is not possible to “visualize 4D”

    Sure it is.

    • 3 spatial dimensions + time
    • 3 spatial dimensions + 1 color dimension (grayscale)
    • 2 spatial dimensions + 2 color dimensions
    • etc

    And that’s not even counting projection. All the time we interact with 3D data that’s projected to 2D (almost every photo you’ve ever looked at). There are similar ways to project 4D to 2D.

    (Not defending the video or anything, just pointing out that visualizing higher dimensions is something we know about for ages.)


  • I think the reason Zealandia is called a “submerged continent” is because it is made of continental crust rather than oceanic crust.

    But IMO the best geologic definition of continents is by tectonic plates, which mostly matches up with the cultural definitions of the continents.

    For the major continents, we have these plates:

    • North American
    • South American
    • Eurasian
    • African
    • Australian
    • Antarctic

    There are several smaller plates too, like the Caribbean, Indian, and Arabian plates. IMO, we should consider these independent continents.

    There is also a dedicated Pacific plate. The ring of fire is the border of this plate.

    New Zealand / Zealandia is on the ring of fire. Half on the Australian plate, half on the Pacific plate. You can actually see the border of the two plates when you look at the topographical map of Zealandia.












  • Let’s say you write a novel. It’s really really good. But no one reads it because no one ever hears about it.

    Later, I stumble upon your novel and recognize how great it is. Then I republish it verbatim, except with my name as the author. I am much better at business and marketing than you, so it goes viral. I receive millions in sales, am tapped to produce a movie version, and win a Pulitzer for it.

    Is that fair? Or should you have some rights in all of this since it was your copy?
