I cannot visualize that Ele. I will try to work on it though because I know you would never lie to me. If you say you made a one-sided pancake I would have to believe you though it would be very difficult. Thank you for your reply.
Yep, had one. So did a coworker. He, I and the others in out department used to "flip" to see who would buy coffee, the "odd man always bought. (I think it was about 20-cents a cup back then.) For some reason both his and my coins always came up "heads". Never paid for my own coffee the whole time I worked that job.
(His coin and mine were made from machining down the "tails" side of a quarter to 1/2 thickness and soldering the two halves together.)
In this 3-D world, every object has length, width and thickness, including coins. paper is thin, but it still has some thickness. Controversies have many sides. Either/Or is a gross oversimplification.
