The ancient inventions that made the modern world

KERA's Think

Without nails and other simple inventions, we wouldn’t have bustling megacities of today. Roma Agrawal is an engineer, author and broadcaster best known for working on the design of The Shard, Western Europe’s tallest tower. She joins host Krys Boyd to discuss simple inventions such as the rivet and string that we don’t think of as particularly revolutionary but which carry all the innovations of today on their shoulders. Her book is “Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way).”
