Infinite Grid of Resistors
- chris_wot 13y agoI remember a Google talk where Randall Munroe talked about working with his Professor for hours on a solution to this problem.

- mathattack 13y agoPhysicists are two points, mathematicians three. :-)
- berrypicker 13y agoIt was this one, starts at around 15 minutes. http://www.youtube.com/watch?v=zJOS0sV2a24 http://www.youtube.com/watch?v=zJOS0sV2a24 Very good talk overall.

- agumonkey 13y agoThe whole website http://www.mathpages.com/home/ http://www.mathpages.com/home/ feels like euler project times itself
- mathattack 13y agoIndeed. Just a few looks and I realized that I needed to stop until I get home. I know I won't be getting much sleep tonight.

- jvandonsel 13y agoI remember getting this as a homework problem in an undergraduate EE course. (bastards!) Only years later did I find out how to actually solve it.
- sbisker 13y agoCould be worse...I got this question on a mid-term in my Intro to Circuits class. The mathy folk all thought the test was awesome, and the systemsy folk all thought the professor was a jerk. :P
- peterbotond 13y agoi had it as a homework in physics. and another similar of a cube with capacitors at each edge.
- judegomila 13y agoLuckily the grid tends to infinite resistance in the limit. Also interesting -> Infinite grid of capacitors (tends to 0 at infinity): http://arxiv.org/pdf/0905.0054.pdf http://arxiv.org/pdf/0905.0054.pdf Infinite sphere resistance (tends to infinity): http://physics.stackexchange.com/questions/48439/resistance-between-two-points-in-an-infinite-metal-sphere-cube http://physics.stackexchange.com/questions/48439/resistance-...
