	The product of of two rotations		2006-12-17
		Katie pose la question : Is the product of of two rotations over a different center point always a translation? Walter Whiteley lui répond.
	Rolling Circles		1999-09-12
		Craig Ellis pose la question : We have a circle of radius 3. inside the circle and tangent to the circle of radius 3 at one point is a circleof radius 1. The question is if we could roll the smaller circle around the inside of the larger circle how many revolutions would it take to get around to where we started. Chris Fisher and Walter Whiteley lui répond.
	Shape-preserving transformations		1999-05-04
		J McAndrew pose la question : A shape preserves its shape if a rotation, translation or scaling is performed on it. Are these the only continuous transformations which have this property? These transformations if performed on the parts and then summed have the same effect as the transformation being applied to the whole; are these linear transformations? Who, and what area of mathematics has classified all transformations of this type completely? Chris Fisher lui répond.
