The White House today holds 142 rooms on six floors, the floor space totaling approximately 55,000 square feet. It has hosted longstanding traditions such as the annual Easter Egg Roll, as well as historic events like the 1987 nuclear arms treaty with Russia.
This parameterization is based on the topological definition of a MÃ¶bius strip as the rotation of a line segment around a circle, with half twist. a is the radius of the circle about which the line is rotated, u is the angular position around the circle of the segment, and v is the position along the horizontal line.
To obtain a MÃ¶bius strip, start with a strip of paper. Twist one end 180o (half turn) and glue the ends together (the avi file takes 267264 bytes). For comparison, if you glue the ends without twisting the result would look like a cylinder or a ring depending on the width of the strip.
