which is this?
1) How do you make a mobius strip? How do you make an annulus? 2) Why does a mobius strip have only one side? 3) How many sides does a strip made with 2 half twists have? One with 3 half twists? How many sides does a strip with 46 half twists have? One with 511? 4) How many edges does the annulus have? How many edges does the mobius strip have? How many edges do the strips with 2, 3 46 or 511 half twists have? 5) a) Is there a connection with the number of sides and the number of edges? Explain. b) What is the connection to the number of half twists and the number of sides? c) What is the connection to the number of half twists and the number of edges?
6) What results when you cut the strip down the middle? Explain precisely. (What are the pieces, how are they linked, etc) 7) What if you cut the pieces resulting from above down the middle (i.e. cut the original strip into fourths)? 8) What if you cut the original strip into thirds? How many cuts does this require? 9) Summarize the overall pattern and give as many conclusions as you can.
It passes through itself like a ghost through a wall!
The Klein bottle results from sewing together two mobius strips along their single edge.EXPLAIN.
