Chris Budd: “Space science is one of HM Government’s ‘eight great technologies’. In this lecture I will explain the mathematics behind satellites, showing how they are controlled, how they are sent to distant planets and how they transmit and receive data over vast distances.
I will also explain how GPS systems work and show how General Relativity plays a vital role in making GPS systems so accurate. I will finish by showing a link between space science and Origami.”

Collision and convergence in Truth and Beauty.

Radio 4 – In Our Time with Melvyn Bragg.
“Melvyn Bragg and his guests discuss Einstein’s theories of relativity. Between 1905 and 1917 Albert Einstein formulated a theoretical framework which transformed our understanding of the Universe. The twin theories of Special and General Relativity offered insights into the nature of space, time and gravitation which changed the face of modern science. Relativity resolved apparent contradictions in physics and also predicted several new phenomena, including black holes. It’s regarded today as one of the greatest intellectual achievements of the twentieth century, and had an impact far beyond the world of science.”
