Below are some of the photographs taken at the talk given by Professor Ian Morison, an Astronomer from Manchester University. The subject of his talk was ‘It’s about time’. He examined how the passage of time has been measured over the centuries – from sundials, to atomic clocks; how its precise measurement was important to navigation, the requirement and problems associated with synchronising time within countries and then across the world. He will also tell how Einstein’s theories show why clocks are affected by gravity and relative speed and how this has to be taken into account for GPS to work. Finally, Ian discussed how we now know when time began – at the origin of our Universe some 13.8 billion years ago.
His talk was very well received with approximately 98 people in attendance.
