The annual Physics 55 event took place in May with over 100 alumni, staff and students gathering in the UCD O’Brien Centre for Science. Attendees enjoyed catching up with old friends, sharing memories and hearing from Associate Professor Janine Splettstoesser on “Heat Engines at the Nanoscale” and “So Far with LOFAR” from Associate Professor John Quinn. Professor Padraig Dunne presented this year’s Thomas Preston Scholarship recipients with their award; which is supported by UCD alumni and donors. Following this, guests retired to the Physics Common Room for refreshments. Plans are already under way for Physics 56 for next year – join us on 21 May 2020 – email alumni@ucd.ie for details.
