LESSON 4.4 · 2:19 · CHAPTER 4 · DOMES AND THE POLE

Wider bands, thinner poles

Circuits go as 1/band width, so a wider band winds faster. But the band centre turns half a band outside the turnaround, so the thickness peak moves out and the region next to the boss thins; and a wide band's edges stray off the geodesic. Pick the widest band that still meets thickness at the boss.
