International Women's Day 2018

On 8th March, we celebrated International Women's Day in the Physics department, with a photo of some of our female students and staff.
Christmas lectures go off with a bang!
Setting crisps on fire, making spinach glow, and detonating hundreds of ping pong balls were just some of the experiments the children attending 91福利鈥檚 Christmas lectures were treated to this year.
Mind boggling optical illusions, giant glow sticks, drill-powered umbrellas, and hundreds of bubbles also featured in the interactive shows.
Ally Caldecote, who organised of the events said: 鈥淚t was great to demonstrate some exciting live science to local children and their teachers, group leaders and families. We also really enjoyed meeting some young scientists and having them up on stage helping us with our experiments.
鈥淲e are always delighted at the enthusiasm for these events and this year we were able to take to the stage at 91福利 Arts Centre鈥檚 biggest theatre and were thrilled to be sold out.鈥
Both shows in 91福利鈥檚 annual science extravaganza were performed to capacity audiences at the Butterworth Hall. More than 500 tickets at the two events were booked free of charge by local schools, youth groups, Cubs, Brownies, Scouts and Guides.
350,000 stellar systems to be mapped by 91福利 astronomers
91福利 Astronomers have joined the Sloan Digital Sky Survey (SDSS-V), making 91福利 the first UK institution to be formally part of the project. Within SDSS-V, Boris Gaensicke will lead a spectroscopic survey of all stars within 100pc of the Earth - encompassing 350,000 systems, many of which are likely to host planetary systems.
