SUMMARY:Monthly Meeting 15 Feb 2023
DESCRIPTION:Pulsars and our understanding of the cosmos\nSince their discovery in 1967, observations of pulsars – the incredibly dense, highly magnetic, rapidly rotating remnants of supernova explosions – have been used to increase our understanding in many areas of fundamental physics and astrophysics. In this lecture, Dr Ferdman will discuss the state of astrophysics leading up to and including this momentous discovery, and how observation since then of these cosmic lighthouses has shed important light on our understanding of the Universe: from testing Einstein’s theories, to probing extreme conditions that we could never hope to reproduce on Earth.\nAbout this month’s speaker\nDr Robert Ferdman ( https://research-portal.uea.ac.uk/en/persons/robert-ferdman ) is a lecturer in Physics in at UEA.\nHis research work focuses on observational astrophysics, particularly on the study of pulsars. Pulsars are the neutron star (NS) remnants of supernova explosions. They produce radio emission beams from their magnetic poles, which are detected once per rotation, every time the beam sweeps past our line of sight. They often display outstanding rotational stability, approaching that of atomic clocks over timescales of several years. Dr. Ferdman takes advantage of the astounding timing precision of pulsars to perform the most demanding tests of Einstein’s theory of general relativity. You can read more about his research here. https://research-portal.uea.ac.uk/en/persons/robert-ferdman ( https://research-portal.uea.ac.uk/en/persons/robert-ferdman )\n—-\nAnyone is welcome – beginner or expert – and there is no need to pre-book. A small charge applies to help us cover costs (typically £3 for non-members; £2 for NEAS members; U16s free). Doors open at 7.30pm with the talk starting at 8.00pm.\nNote that if you are using satnav system, the postcode may not take you directly to the hall – please check this Google Maps link if you aren’t sure: https://goo.gl/maps/fNxmg9qnAYm\n \nCovid Precautions\n\nYou are encouraged to wear a mask and you are asked to be respectful and sensitive to the medical circumstances of others\nWhat to do if you have coronavirus (COVID-19) or symptoms of COVID-19\nThe NHS says:\nWhile you’re no longer legally required to self-isolate if you have COVID-19, you should try to stay at home and away from others to avoid passing on the virus.\nTry to stay at home and avoid contact with other people if you:\nhave any symptoms of COVID-19, and have a high temperature or you do not feel well enough to go to work or do your normal activities\nhave tested positive for COVID-19 – this means it’s very likely you have the virusFor full details please see https://www.nhs.uk/conditions/coronavirus-covid-19/self-isolation-and-treatment/when-to-self-isolate-and-what-to-do/ ( https://www.nhs.uk/conditions/coronavirus-covid-19/self-isolation-and-treatment/when-to-self-isolate-and-what-to-do/ )\nIf you have Covid symptoms and have not taken a test, please do not attend.\nThere will be a section of the Hall for exclusively mask wearers. If you are wearing a mask you may of course sit where you want but if you are not wearing a mask do not sit in the masks only area. We have vulnerable people in our club and we want to make our meeting accessible for them.\nWe will ventilate the Hall to the best of our ability.\n\n
