A Review of the Search for Extra-terrestrial Intelligence (SETI)

 

This talk looks realistically at the prospects that extra terrestrial intelligences may exist and be able to be discovered in the Galaxy. It analyses the problems of communication and explores the idea that technological civilizations capable of communication may not exist for long enough to be discovered.

Understanding of the possible technological "Choke Point" that dooms civilizations to a short life span is investigated with reference to our development on Earth.

The Geological History of Ross-on-Wye


700 million years ago, our small part of the earth’s crust emerged from the sea for the first time, as part of a chain of volcanic islands, rather similar to Java and Sumatra today. These islands lay near the Antarctic Circle, off the northern coast of a large supercontinent, known as Gondwana, under which the floor of an ocean – the Iapetus - was being destroyed down a trench. This talk will aim to chart the geological “adventures” of this small section of the crust as it moved northward to its present position over hundreds of millions of years, and to outline the evidence contained in local rocks that allows such a story to be constructed.

Chief Exec Officer of the Institute of Physics.


Physics of Thunderstorms

Thunderstorms are ever-present across the globe and for centuries have had a strong cultural influence.  The talk will explore what we know of thunderstorms and how this has helped us understand how and where they occur; how to mitigate the weather hazards they create and how we can use this knowledge to make predictions or warnings.
