DR. .JAMES GRIME: So today we're going to talk about oneof the great unsolved problems in mathematics that went backto the Ancient Greeks, thousands of years ago, whichwas eventually solved in 1882.And the problem is called squaring the circle.And you may have even heard of the problem as a metaphor forsomething that's impossible to do.The question is, can you make a square with the same area asthe circle?Now you have to understand the rules.In Ancient Greece they didn't have algebra.So they could only construct numbersusing lines and circles.So you could only make things using a straight edge--like a ruler, but not a measured ruler, just astraight edge--and a compass.So lines and circles, those are the rules.Those are the rules the Ancient Gr...
