Richard Bulliet

Richard W. Bulliet taught Middle Eastern history and the history of technology at Columbia University from 1976 to 2015. In his new book The Wheel he challenges long-held assumptions about the place where wheeled transport was first invented and the reasons for it. He presents new evidence that locates the earliest known wheeled transport not in the Middle East but in the mines of Eastern Europe. 

Jagjit Singh Srai

Dr. Jagjit Singh Srai is Head of the Centre for International Manufacturing at the University of Cambridge. He looks at how to design supply chains - the logistics behind the transport of food and goods, often from one continent to another. Using his first-hand experience of creating a supply chain to transport gherkins in Southern India to the rest of the world, Jagjit explains how timing is vital:  from an awareness of the perishability of the produce to understanding the complex web of transport links which are needed to deliver the product in time to consumers who now expect "same day delivery" at the touch of a button. 

Valerie Inertie

Valerie Inertie is an award winning Canadian Cyr Wheel dancer. The Cyr Wheel, which consists of a single large ring that the performer spins inside as it rotates, was invented in the 1990's by Daniel Cyr. Valerie was taught personally by Daniel Cyr, and then she built her own wheel, becoming the first female wheel artist and pioneer in this field. The many companies she has performed for include the Cirque du Soleil. Valerie explains how her act is not just to do with technical skill and artistry, but also being aware of the physics of the rotation of the wheel.
