Mathematician and television presenter Hannah Fry hosts a series revealing the miraculous technologies that define the modern world. Seemingly ordinary inventions, like the bank card, have fascinating stories to tell about their origins, proliferation, and their role in shaping the world as we know it today. While celebrating the convenience these objects often bring into our lives, Hannah also casts a critical eye to their less savoury real-world impacts, asking whether all this technology can come without a deeper cost to society.
