    Why should I waste my time trying to figure it out?

    It would be so much easier to just sue the people that already have it figured out! Don't you think so?

    I think so! So that's what I'm going to do!

    There's so much that just doesn't make sense! So why not just drag the people that aren't making sense into court and force them to make it make sense? Sounds like a plan to me!

    Придурок ты что не орывая руки не можеш нарисовать конверт
    Хватит смотреть сколько Я крови сдаю
    У меня Погуще и по темнее
    Если раставить три одинаковые стаканчики на разном растоянии
    то С угла они будут казаться разныго обьема
    Хотя на самом деле Все одинаковые
    И хватит меня хоронить в бронзовом писке
    Я не играю с тобой В Твистер
    Ты деревянный
    Твои руки не сгинаються и узнаваемые Раны с волосней

    for the 9 dots, cant you just draw an X and a + and still be right? as for the pin and candle, sticking a pin in the bottom of the candle then using melted wax to bind 2 flat ends of the pins together would work also…

    Simple logic
    1 0
    On off
    and deduction
    applied to problem and further simple questions using same formula
    applied to the greatest eternal questions will be answered.
    Binary is the lowest language
    Foundation of knowledge built upon simple logic.
    Computer language
    Is the key to examine any question.

    Umm.. I have glued those exact candles to walls using their wax heaps as a kid.. apparently I was solving some amazing problem according to this video? Or I mean just thumb tack the box to the wall and stick the candle in the draw and light the candle with a match… the box could be tacked in in 2 orientations that would work, or 4 if you consider the box to have an arbitrary "top" you could carefully and patiently drill a hole in the candle with a match, jam the match into the cork board and hang the candle on the match… I mean its not hard.

    P vs NP I guess..

    yea, but did you clearly TELL WHOEVER was doing this experiment that he/she can use everything given (i.e. match box) to attach the candle to a wall???? You said ATTACH THE CANDLE TO A WALL!!! ATTACH MEANS connected to something… So what you did is bullshit and misleading

    tacs: 1 — use 4 to pin a 5th with its pin facing out; Pin it on the candle base and now light it

    What the psychology has to tell us about problem solving? Clearly hints are helpful. Thanks, never thought about that, very insightful, I don't even know how I'm going to sleep tonight with my mind blown that way.

    I get the dot one's solution is probably the only one that works but for the other two, you can have alternative solutions. Especially for the one with the glasses…

    The trouble with near all of these tests is that presents a problem with a suggest limit and to solve them you have to ignore the limit. The match box was not listed as a thing you could use. Drawing a line to empty space was not suggested by the dots. So the person whom solves these things those ways are breaking the rules and open it to nearly any solution. For example the candle thing never said I couldn't put the candle on a wall that was laid on the ground. The dots never said I couldn't fold the papers and push a pencil through it. I find the suggestion of limited options in which when people follow those options their efforts are labeled failure while the solution means breaking the limits to be dishonest.

    For the glass problem, once you have the 5 and 3 oz glasses can’t you just pour 1 oz from the 5 oz into the 3 oz glass? Or am I completely missing the point… 🤔

    Noo, that's wrong,
    When people said, connect all the dots with four lines, in my mind the solution here is not what i expected, you have to connect all of them with all the dots around them, not like this,

    well I actually thought of another way to solve the candle problem , it might sound crazy but , we canmake a hole on the candle ( preferrably near the bottom) and gently put one match inside the hole so it creates a horizontal line , then by putting 2 thumbtucks , one of each side of the match we can attach the match on the wall and then turn the candle so it doesnt face the wall , then light it !

    Problem solving is the systematic approach whereby meaningful solutions are derived which when implemented address the problem.

    The steps are

    1. Define a problem statement precisely. Remember that vaguely defined problems can only lead to vaguely defined solutions.

    2.  Assess the severity of the problem ( A mix of urgency and criticality) to define how soon a solution needs to be derived and implemented. 

    3. Generate meaningful possible solutions through brainstorming with relevant team members, Analysing pros and cons / cost/ time factor associated with the solution, previous successful solutions based on case studies etc.

    4. Adopt the best possible solution (s)

    5. Create a feedback and review mechanism to check if the solution is actually providing the results.

    For this the solution implementation can be done as per phases and with each phase we can evaluate the effectiveness of the solution.

    6. Keep backup solutions ready in case the intended solution does not work.

    At 6:27 , if the balance of what is left in the glass in written on the top. then how did you have a 5 ounce balance in the 1st glass after pouring it into the 5 ounce glass. the balance should be 3 ounces in the first glass. Anyway you got the 4 ounces.

    In the dot one I used a curved line to get to the next dot so that I don't waste a straight line

    the 9 dots can be done with 3 lines, all connected in a sort of z shape
