Topology is concerned with the properties of a geometric object that are preserved under continuous deformations. There is no “bottomology,” but there are jokes.

Wikipedia: Topology
In mathematics, topology (from the Greek words τόπος, ‘place, location’, and λόγος, ‘study’ ) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself.

Normally to take topology, you have to have taken the prereq, bottomology. Let’s just say I placed out of that one.

If there’s a field called topology, why is there no field called bottomology?

But bottomology is a real field of science: the study of the bottom surface of earth; it’s just a purely theoretical discipline, since every attempt to send an expedition there failed.

UP Diliman is considering opening a ‘minor’ track for its students. For example, your degree is BA Political Science, and you are allowed by your curriculum to have a minor in another field of study, e.g. History. There will be rules on who can and what ‘minors’ one can take.

i think generally people take versology first then specialise but i dont think its unheard of to jump straight into topology or bottomology respectively, depends on your uni i think

So what’s the deal with topology? Is there a bottomology and a middlology too?

If you think of a topology for a set A as being a list of open sets on A, then a bottomology on A is the list of closed sets and a versology is the list of sets that are both closed and open

Well if topology is the study of surfaces, bottomology is the study of holes
