Let&rsquo;s talk about shuffling a deck of cards! You know, when you&rsquo;re getting ready for a game of poker, solitaire, or even just Go Fish, you give the deck a good mix. Most of us probably just shuffle a few times, maybe three or four good riffle shuffles, and feel pretty confident that the cards are well and truly mixed up.

Ever just stop for a second and wonder why almost every single one of them is perfectly <em>round</em>? It seems like such a simple design choice, but it&rsquo;s actually got a really clever and super practical reason behind it that, once you hear it, you&rsquo;ll probably go, &ldquo;Whoa, I didn&rsquo;t know that!&rdquo;</p>
