Saved you a click: one hole

Well, that was anticlimactic. Same as a coffee cup. Objects are topologically the same if they can be continuously transformed (no cuts basically) into each other.

  A coffee cup doesn't have any holes...?

    The handle is one
    - JshWright 8y ago
      Oh, I think that may be a language quirk. If it has a handle I would call it a "mug".

Thank you. You're a genus.

Saved me a click, saved me from learning things: an analogy for today's convenient internet!

Isn't that the intuitive answer?

I'd guess you're the kind of person who would pick up a murder mystery, read the first few pages to find out who was killed, the last few pages to find out who did it, then put it down and move on. Sometimes value lies in the journey, not in the destination. So you have an answer - one. Of what value is that? Not a lot. Those who watch the video will potentially learn a lot more than a glib and useless answer to an apparently pointless question, and for those who work in a technical area, perhaps knowing a little more about topology will come in useful one day.

  One is the obvious expected answer, so the value is not wasting time with the video. It's like a murder mystery where the culprit is obvious from the beginning, but the whole book is spent talking about hypothetical angles. If the answer was 0, 1.5 or 2 in terms of topology, or anything else, then it would be interesting to hear.

    So did you already know about persistent homology? Are you aware of its potential applications to machine learning? Did you already know why some people say the answer is 2? Consider all the people who (a) did not know about these things, and (b) didn't bother to watch the video because of your post. I'm sure you feel like you've done them a favour, but have you really?
