  1. TimeSpaceLightForce added an answer to a question Minimize the perimeter   

    For first thought..will it fit  in a 9 x 10  with 1 blank square inside or corner?

  4. TimeSpaceLightForce added a question in New Logic/Math Puzzles   

    Half-balls
    A bearing factory cuts four steel balls into halves with a gram or 1% difference in weight due to laser error.
    The eight pieces were all mixed up in a collecting bin and shall be paired into 4 similar spheres..
    Using the balance scale and/or the digital scale..How can it be done quickly?

  5. TimeSpaceLightForce added an answer to a question Triangle with a given perimeter   

    beats me..
    Looks like a very fine puzzle!

  6. TimeSpaceLightForce added an answer to a question Triangle with a given perimeter   

    measure MC length
    measure the 2 angles formed with vertex C
    apply sign law for triangle, calculator is needed.
    4 unknown lengths, compute angle form with vertex M
    Use compass and straight edge to make that angle on the ground

  7. TimeSpaceLightForce added an answer to a question Triangle with a given perimeter   

    For field work using Meter tape 
    as compass and ruler.
    given length p..
    make the cutting lines from M
    let intersection points be c1 & c2 )
    measure C-c1 , C-c2 & c1-c2
    add and compare to p..
    adjust c2 along its line
    measure C-c1 , C-c2 & c1-c2
    add and compare to p..
    repeat until distance sum=p is ok

  10. TimeSpaceLightForce added an answer to a question Center of Gravity   

    Lets see..


     
    Not like how I imagine it ( center of gravity in x-y-z symmetry). But that is better!

    This is a simple mechanics+ geometry puzzle..
    I'm not sure if the "2015 MIT Mystery Hunt"  is a type of metapuzzle?

      It does because the title is connected to the figure and the question..   The firgure are rectangles with elipse on top of one end.. no color, but common sense tells us it represent an arrangement  of matchsticks that need to be modify for higher symmetry..   You could see dozen solutions easily , Yet chosen the square cross..why not the 2x2 square?  why not the tic-tac-toe? This is where you supposed start to wonder and recheck and  reconsider everything.. or 'look inside the box'.
