    If it's in English you'll be stuck at 4, but if it's in Indonesian you'll be stuck going between 4 and 5. (4 = empat and 5 = lima, lima has 4 letters and empat has 5 letters).

    Stirring would not follow the fixed point theorem if the spoon touches the walls of the cup during stirring since it would create a hole and all points can then move around the spoon.

    When you introduce the spoon to the cup of coffee, do you not in fact create a hole in the coffee? And thus there would not have to be any point remaining in its exact position. Appreciate answers, thanks :)

    I cringe every time I hear them talk about the various types of infinities. Infinity is a concept and NOT a number. Therefore, any sort of comparison of infinite sets is meaningless. This also makes many of the so-called infinity paradoxes meaningless because they are treating infinity as a number.

They swap sides at the exact point they touch Dark|Gray to Gray|Dark. All other colours/squares are irrelevant at that point.)
    If i am getting the concept wrong, could someone please explain it more in depth.
    Also at 3:44 the bottom square is lighting up in the presentation when it shouldn't. It's not the middle square.
