12th April 2021 (Zoom 7pm) – 5G: The Need, Technical Challenges and Impact

Prof Nigel Linge

Professor Nigel Linge, University of Salford, School of Computing, Science and Engineering, will be talking about 5G. From his website, this is what Nigel says about his talk: “In December 2017, the world took an important step forward in the development of the next generation of mobile phones when the first standard for 5G was published. The journey to this point began back in the 1980s when the first generation of analogue mobile phones was introduced. The move to 2G in the 1990s heralded improved communications and the introduction of data services. The third generation subsequently brought better Internet connections and then 4G offered high-speed broadband connectivity. This talk however, examines the latest moves towards 5G, what that entails and what its impact might be. The talk will explore why 5G is needed, how it differs from 4G, what technical challenges need to be overcome and which new applications and services will become available.” You can see more about Nigel on his website: https://www.engagingwithcommunications.com/index.html

Following on from Professor Linge’s talk, here is a link to a paper on 5G and safety concerns: https://www.theiet.org/impact-society/factfiles/engineering-safety-factfiles/allaying-health-concerns-regarding-5g-and-exposure-to-radio-waves/ . Also, the triangle that Nigel showed as one of his slides was felt by several people to be very useful – it was created by the International Telecommunications Union as part of a presentation IMT-2020 NETWORK HIGH LEVEL REQUIREMENTS, HOW AFRICAN COUNTRIES CAN COPE. The specific page (14) of the presentation can be viewed here.

1st March 2021 (Zoom 7pm) – The Beginning of Everything

Dr Steve Barrett, Department of Physics, University of Liverpool will talk about the beginning of the universe. Several of us recently attended (virtually) Kirkby SciBar and saw Steve giving a talk about Black Holes, and were very impressed by his presentation, so we are very pleased that he is able to talk to us.

You can see details of all Steve’s talks (including this one) at https://www.liverpool.ac.uk/~sdb/Talks/Outreach.html

1st February 2021 (Zoom 7pm) – Living with a Shrinking Nile for 6,000 Years:geoscience and archaeology in Northern Sudan

Prof Jamie Woodward, who spoke to us in June 2019 about microplastics in Manchester’s rivers, will return to talk to us about the Nile. More details to follow.

NB this talk was going to be given in March 2020, but unfortunately Prof Woodward had to attend an out-of-town conference that day. It was rescheduled for the summer, but had to be postponed again because of the pandemic. Fingers crossed for this time!

4th January 2021 (Zoom 7pm) – Above and Beyond: Drones Are Changing the Way we Monitor Volcanoes

Dr Emma Liu, University College London will give this talk. Some background (taken directly from https://festivalofgeology.org.uk/): “Volcanology is undergoing an aerial revolution. Drone technology is changing the way we collect data across the geosciences, especially in fields that require measurements over large spatial areas or in potentially hazardous locations; not only can we see the Earth from a new perspective, but we can also collect measurements and samples from places that would be otherwise inaccessible. As global populations now live closer to active volcanoes than ever before, volcano monitoring – through measuring gas emissions or topographic changes, for example – is becoming increasingly important in today’s world. In this talk, I will introduce how aerial strategies are improving our ability to both monitor and respond to volcanic hazards, and how these approaches are being integrated into operational monitoring at volcano observatories around the world. Drawing on my own active research from volcanoes in Papua New Guinea, Hawai’i and the South Sandwich Islands, I will highlight how we are now pushing the frontiers of drone design and deployment to fly higher and further than ever before; targeting beyond-visual-line-of-sight flights at high-altitude active volcanoes.”

7th December 2020 (Zoom 7pm) – Invasive Plant Species

Invasive Plant Species – Bogeyman or Ecological Disaster?

Dr Arthur Broadbent of the School of Earth & Environmental Sciences, University of Manchester will lead the discussion.

“Novel weapons”, “Enemy Release” “Invasional Meltdown” – these are some of the more popular hypotheses proposed to explain the paradoxical success of invasive plants. But is this militaristic language justified? Are invasive plants really such a threat? And what does explain their unlikely prominence?

Dr Broadbent will present the evidence surrounding the underlying causes of plant invasions, and with a more nuanced take on their ecological impact.

NB this talk was originally going to be given on 2nd September 2019, but had to be rearranged to April 2020 due to an unforeseen bovine intervention, and then postponed again because of the pandemic.
