I'd like a physics analysis of how flat/hard a surface you need to roll a D65536, how long it would take to settle, and how good a microscope you'd need to read the top face.
Is there, like, 99designs for physics questions? I'd happily pay $99 for the answer, then post it here like I worked it out myself.
- hnuser123456 4y agoa 1ft diameter d65536 could be broken into surfaces with area 4.45 square millimeters, or a little over 2x2mm. With good eyes and enough squinting, a microscope might not be needed. maybe fill it with liquid with a tiny air bubble to find the top face 1in diameter, however, gives 0.175mmx0.175mm per face, or about the width of a hair by the width of a hair.
- thematrixturtle 4y agoI wonder how much bias engraving or even painting the numbers on the die would introduce? The weight of "1" will be noticeably different to "58888".
- eesmith 4y agoUse a 7-segment font and two paints with the same density, with one paint the same as the background color. For each digit, paint in all 7 segments. For each number, draw all 5 digits.
- JoeAltmaier 4y agoI'd look at the bottom face. Because you have a reference (the table) for the selected side, not just guessing which side is toppiest.
