Cul-de-sac Memes

Two perspectives on neighborhoods that couldn't be more different! Topologists get excited about an "open ε-ball of p" - basically a fancy mathematical bubble around a point where they study shape properties that don't change under stretching or bending. Meanwhile, urban planners look at those soul-crushing suburban cul-de-sacs and spiral into existential despair. One sees elegant mathematical structures; the other sees concrete evidence that we've engineered our own isolation. The duality of professional perspectives is just *chef's kiss*.
