Weird and Divine, O Wondrous Bottle of Klein!
<p>The Klein Bottle was discovered in 1882 by the German non-Euclidean geometer and educator <a href="https://en.wikipedia.org/wiki/Felix_Klein" rel="noopener ugc nofollow" target="_blank">Felix Klein</a>. Weird and most wonderful it is indeed. And the limerick, above, as we shall see, is one precise description of its topology. But it is not the simplest, as a single Möbius strip can suture itself into a Klein Bottle, which can then split into two Möbius strips — this is like "asexual" Möbius Band reproduction! Or two Möbius strips can get it on "sexually" as in the Moser Limerick to produce a Klein Bottle, which splits into two Möbius bands which suture themselves into two copies of the Bottle!</p>
