Re: Piston

Making sure I understand the question correctly - the piston will move up get the top inch of it greased, then smear the grease down the wall on its return stroke, making the grease spot 2 inches tall on the wall, so when it moves up again you would say two inches of the piston will be greased, and ...

Re: Sacrifice

Then the optimal solution is: Use all N chickens that are available... I like your optimal strategy for reasons you didn't fully explain: While your numbering scheme still requires a minimum of 7 chickens to be able to identify 101 cans (same as the first solution in this thread), the more ...

Re: Escape the Frictionless Circle

I have skimmed, but not read all, of the responses and have a suggestion that relies on two ideas: 1. There is friction between you and the block. 2. There is potential energy in the system (you are upright and can fall down) that can be converted into horizontal momentum using that friction. You do...
