Beyond Infinity

I’ll admit: I approached *Beyond Infinity* with skepticism. Math audiobooks often either dumb things down or drown you in jargon. But Cheng’s book—*performed* by Moira Quirk with the energy of a favorite professor—does neither. Quirk’s delivery is *just* theatrical enough to sell Cheng’s quirks (like her obsession with cake-cutting as a metaphor for continuity) without veering into cartoonish. Her British lilt adds a layer of charm, especially when she deadpans lines like *“Infinity is where math meets philosophy—and then they both get drunk.”* The book’s strength lies in its *structure*: Cheng starts with childlike questions (*“What’s the biggest number?”*) and spirals into legit mathematical philosophy, like how infinity exposes flaws in our intuition. The production shines in chapters where she contrasts finite and infinite sets—Quirk’s pacing slows, letting you grapple with the idea that some infinities are *“bigger”* than others. My only gripe? The final chapter rushes through applications (like how infinity shapes AI), leaving me wanting more concrete examples. And while Cheng’s tangents about music and baking are delightful, they occasionally derail momentum. Still, this is the rare math book that doesn’t just *explain*—it *invites*. By the end, you won’t just understand the difference between countable and uncountable infinities; you’ll *care*. Perfect for listeners who loved *The Joy of x* but crave more personality—or anyone who’s ever stared at the night sky and thought, *“Wait, how does this even work?”*
