I was so stupid. My son has a thomas train set. His little brother had a poopy mess right in the middle of tracks he had set up, so I took all of them and threw them in the bathtup to clean them. I forgot about wood expanding in water...now the pieces won't fit together. Will they go back after they dry, or have I just ruined his train set?

A geometric point is defined as having no dimensions. It seems to me that two spheres, if they are perfectly hard, so they cannot bend at all, and they are perfectly round, would only be able to touch on a "point." And a "point" has no dimesions.

When a bird sits on a telephone wire it doesn't get electrocuted. My understanding of this is that it is not earthed and so provides greater resistance than the wire. The electricity just goes down the wire. But what is confusing me is.. how does the electricity 'know'? Surely it has to jump into the bird to find it doesn't lead to earth? In which case the bird would be electrocuted. How does the resistance at the point of contact with the wire change if the bird is earthed?
