The entrance to the Urdd is on the outside of the Wales Millennium Centre, near the Senedd. Event starts at 17:30.
Antimatter was discovered in the 1930s and since then positrons have found numerous applications in atomic and materials science, engineering and medicine.
Recently, physicists working at CERN have learnt how to create and capture atoms of anti-hydrogen. A few of these anti-atoms have been held for periods longer than 15 minutes.
The talk will cover the history of antimatter, why the positron is so useful, the current experiments, and the motivation for undertaking these experiments.
The latter will involve one of nature’s great conundrums: the absence of bulk antimatter in the current epoch of the Universe.
Following the talk there will be an IOPW members meeting.
This will be an update on the activities of IOPW and an opportunity for members to raise and discuss possible future activities. There will also be an opportunity to have a chat over a cup of tea or coffee.
