Pretzel = genus 3; spectables = genus 2; donut = genus 1; bowl = genus 0. How would a hollow ball, for example, be classfied topologically?
Also, at the atomic level, everything (pretzels as well as bowls) are more 'holes' than solid. What does topology say about this or what are the boundaries or topology?
