    It is not a coincidence that 2025 is both the square of sum of 1 through 9. and the sum of the cubes of 1 through 9. To the contrary, it is Nicomachus’s theorem: the sum of the first n cubes is the square of the nth triangular number.

      this is fairly easy to prove with induction:
      first, obviously, (1)^2 = 1^3.
      then, suppose that (1+...+k)^2 = 1^3+...+k^3, and let 1+...+k = K for the sake of brevity.
      now, (K+(k+1))^2 = (K)^2+2(K)(k+1)+(k+1)^2.
      since (K)^2 = 1^3+...+k^3 already, we need the rest to be (k+1)^3.
      finally, 2(K)(k+1) = 2(k(k+1)/2)(k+1) = k(k+1)(k+1) = k^3+2k^2+k, and (k+1)^2 = k^2+2k+1. adding these together, we get k^3+3k^2+3k+1, which is exactly the expansion of (k+1)^3.

      actually, looking at my proof again, I see a slight optimization in the last step: the two terms simplify to k(k+1)^2 and (k+1)^2 respectively, so factor out the (k+1)^2 to get (k+1)(k+1)^2 or simply (k+1)^3, no expansion necessary.

      I've been on medication that causes drowsiness for nine years now and for the most part as I've been decreasing the dosage I've shifted from cat naps during the day to the (early) evening time usually 6-10. So I'm half awake when I first listen to Simon's solve whilst cooking using the convention oven so my falling asleep again isn't a great problem. I then either rewatch in the early hours or during the day. I occasionally do the same with Mark's solves but I think due to the later release time I'm likely to be more awake. Live stream sessions I join when awake and normally dose off, rousing as it ends so play back straight away.
      Happy New Year to all of the CTC community.

    31:34 another way I solved the green diamond, was the two white dots on the green diamond would force those four digits in column 5 of the diamond to be the same "polarity" either all above or below 5 (since you can't put a 4 or 6 on the diamond). If you put low digits on the north/south point of the diamond, that takes all the low digits in column 5. So now what do you put in box 2 column 5 to keep the total under 20 in the cage? You can't! So you know the big digits are north/south on the diamond.

I came back the next day and it was still hard. I didn't understand. That is, until I remembered the King's move ruleset. I felt like how Mark usually does when he forgets about chess rules. I quickly asked the question where does r8c4 sit in box 7 and that solved everything. It really sucks to forget a rule, but I'm going to use the excuse that I just woke up. That sounds like a good excuse. Despite my error, this was a really fun puzzle to color and solve. Great Puzzle!

  • @craigyoung8008
    @craigyoung8008 2 дня назад +1

    There's a different way of resolving the whisper line that can be done right at the start, even before examining the colour mapping due to the long cages.
    We can't place the monogamous digits (4 or 6) on the whisper, so the kropki dots in column 5 can't take a 5.
    Which means c5c5 and r9c5 must have the same polarity as the whisper cells at r6c5 and r8c5.
    This places 4 cells of the same polarity on the kropki dots in col 5.
    But if they're low polarity (1234), then the 20-cage in box 2 has minimum digits 5+6+7=18 in c5r1-3.
    This leaves 2 digits to be placed in the cage adding to 20-18=2, which is impossible.
    Therefore, the polarity of the kropki dots must be high. One being 89 and the other being 67.
    The ordering is of course determined by the inability to place 5 on the other kropki dot in box 8 - as Simon demonstrated in the solve.
    Which leaves a 12 pair to complete the low polarity cells of the whisper.
    Also to mention, there was a missed opportunity at 46:00
    Simon probably didn't pay much attention to the 25-cage in row 1, because with 4 cells, that's usually quite flexible.
    But as soon as the 1 is placed in the cage, that leaves 3 cells needing to add up to 24.
    The only way of doing that is with a 789 triple.

    @Simon, there was a much easier way to figure out the polarity of the German diamond. Because of the two white dots, all four highs or lows are accounted for. Then look to box 2 where there is a 20 cage and ask yourself if it can handle three high or three low. The answer tells you the polarity.

      The word "ratio" is not so commonly used, nor so commonly intuitively understood. Double is more common and less likely to be misunderstood or put people off. Technically also, zero is double zero, but the ratio between two zeros is undefined - you'd only need that in a a modifier puzzle, but it keeps the possibility open.

    This puzzle is a warning against the dangers of overusing coloring. Simon made this unnecessarily complicated because he decided to have the puzzle revolve entirely around coloring instead of using the clues the way they would be expected to be used ordinarily and then doing sudoku to simplify pencil marks. And I do know sudoku is not Simon's strongest suit when it comes to these variant puzzles, but this puzzle had a worse display of this than usual, which to be fair, Simon himself admitted. But even leaving aside the sudoku shenanigans, the coloring was out of control, and made the puzzle a lot harder than it could have been for him.

      Simon could have gotten rid of the entire coloring before he reached halfway through the puzzle. This trait of him is quite annoying, but we don't have everything we like in life, as they say.

    i feel like you're too smart for your own good. Looks like you could have used Sudoku to solve some of the numbers in the later half. always impressed seeing your more advanced thought process regardless!

    I thought the right hand side looked more promising and gave box 6 individual colours, I actually worked it out from there and only 20 mins slower. Simon's way made more sense.

      Now watching Simon, I find I made another mistake, but which turned out to be correct by pure chance - my logic was "A 6-cage summing to 21 can only be 123456, so a 5-cage summing to 20 must be 23456". (There are 5 other options.)

    1 + 2 + 3 + ... + n = n(n+1)/2 and 1³ + 2³ + 3³ + ... + n³ = n²(n+1)²/4. And 2025 is where Project 2025 comes into its own.
    12:30 "The Secret" is probably already well-known.
    35:50 These digits were low-hanging fruit for me, although I derived the green line's polarity a different way. Column 5's three cells in the 20-cage had to be low, not high. 4 and 6 were barred from the green line, so the four cells with the dots at the bottom of column 5 had to have the same polarity, and had to be high.

    That is not the most dreadful pencil marking. You haven't seen how I play. Ctrl+a, then ctrl+1 through 9. Everything is process of elimination.

    Love how the word "ratio" can be said to put pepile off yet terms like "integer", "polarity", "oscillating," aren't seen that way. Also, if you aren't familiar with chess, "King's move / "knight's move" are equally acceptable.
    Seems to me if you want to dumb it down (and it's exactly that!) then you ban all those terms as well.

      People's instinctive reactions to certain words aren't always necessarily logical. For example, people have a very negative instinctive reaction to the word "work" but a positive reaction to the term "hard work." Seems illogical, but it's nevertheless true. (Watch some speeches from successful American politicians. You'll find that they may say something takes "hard work" but almost never that something takes "work.")

      This from the only guy who I've ever heard throw out the Latin phrase "ab initio" fairly regularly. But sure, "ratio" is too complicated for us simple folk to understand. 😂

      ...or 4-2-1?
      (8-4-2 could also have been eliminated, but requires the 6-8 pair to be identified in box 1 first.)
