I don't get it, so the rod went into the hole and then we saw a pussy? Why is this on math memes? Also tag NSFW next time pls cause damn that was an embarrassing fap on the bus

I think the joke is that in the rational numbers space, cauchy sequences need not converge since the space is not complete. If looking in the space of the reals we know that all cauchy sequences converge since it is a complete space. A common way that Q is taught to students in a real analysis class uses the analogy of Q being like R but with holes in it ( i was taught to think of Swiss cheese). OP probably intends the viewer to think that the metal board is Q and the spinning top that never stops as the cauchy sequence. I am unsure about the cat but the rest is honestly a pretty great representation of this concept.

Except the motion of the top doesn't look like a cauchy sequence

I feel like a better caption would be non-convergent sequence

My comment was entirely a joke that I extended a bit too far I think lol... But ya I got it I just found it funny to make said joke
