Welcome to the Knutsford SciBar Website

NEXT MEETING – 6.30pm for 7pm, 13th December 2021, The Angel, Knutsford

For our final SciBar of 2021, Professor Jeff Forshaw, Professor of Particle Physics, Dept of Physics, University of Manchester is coming to talk to us about Black Holes. Jeff has spoken to the SciBar twice before: in 2006 (Relativity for Dummies) and 2012 (The Quantum Universe). If you want to know more about Jeff’s interests and career, check out his Wikipedia page. And if you want to pre-prepare some searching questions for him, it might be worth having a look at the Science Daily and Live Science websites (e.g.: https://www.livescience.com/black-holes-expanding-with-universe) where there are many recent articles about Black Holes.

Please note that there will be a £2 entry fee (students free).

We have a speaker lined up for our first meeting in the New Year (10th January) when Knutsford Scibarian and retired metallurgist Alan Daglish is going to talk about Chaos (hopefully in an ordered way!). And looking further ahead, we are contacting a number of possible speakers for the rest of next year. We hope to get some dates in peoples diaries very soon, and to publish a timetable here by early January.

11th October 2021 – A Story of Radioactivity: A Glowing Tale

Dr Louise Natrajan, The Department of Chemistry, School of Natural Sciences, University of Manchester will present this talk. She will discuss the myths surrounding radioactivity, how it was initially thought to have health benefits through to how it is now considered harmful.  She will show how electricity production from nuclear fission can be safely managed, providing that we are able to identify and trace radioactive waste products and describe how the fluorescence of uranium can be used to help clean up nuclear wastes in the environment.

13th September 2021 – An introduction to Machine Learning

In our first live SciBar for 18 months, Paul Roberts, a Management Consultant who advised international Investment Banks on Artificial Intelligence is going to give a talk entitled “An introduction to Machine Learning (commonly known as Artificial Intelligence)”

Paul says “Machine Learning has has been around as a concept for over 50 years but over the past 10 years it has just exploded in power, capability and real implementations. So much so, many of you will interact with real Machine Learning solutions several times a day, quite possibly without realising it.

In this talk, Paul will take you through several key aspects of the Machine Learning story, e.g. the history, the Machine Learning you use today, how it works, the key algorithms, the ethics and what the future might hold.

5th July 2021 (Zoom 7pm) – Tired of Listening? A journey Through the Sense of Hearing

Dr. Kate Slade
Dr Kate Slade

Dr Kate Slade from the Neuroscience of Speech and Action Laboratory in Lancaster University’s Psychology Department is going to talk about her work. This is what she says about her talk:

“Think back to a time when you’ve been in a café or restaurant with a friend, an environment filled with chattering people, yet somehow you are able to tune into a single conversation, ignoring all the other environmental noise. The brain’s remarkable ability to filter out irrelevant noise is known as the ‘cocktail party effect’. It is just one example of the extraordinary processes involved in understanding speech. Although we might hear with our ears, we ‘listen’, process, and understand sounds with our brain. 

“When hearing is impaired, the brain might have to work harder to de-code and understand sound signals received from the ear. This might affect how the brain works, and even cause people with hearing loss to avoid noisy social situations where listening is very difficult. There is evidence that hearing loss and social interaction may increase the risk of dementia, but that we can reduce this risk by alleviating hearing loss, and maintaining social interactions. More than ever social interaction is complicated and isolation is on the rise; what could be the impact of this pandemic on our hearing and memory function?

“In this talk, we will explore the sense of hearing from the ears, through to the brain. We will discover extraordinary ways in which the brain copes, and adapts when hearing is impaired, and what this means for our overall brain function. “

7th June 2021 (Zoom 7pm) – How Do You Observe 1.33 Billion Km3 of Ocean?

This question will be asked by Dr Matt Donnelly, Lead Data Scientist, UK Argo Programme. The oceans play a key role in the climate and provide a habitat for a wide range of marine life, but with an average depth of 3.7km and a surface area of 360 million km2, how on earth do you collect the data to understand its physical properties, how it moves, and how it supports life?

Find out about the robotic Argo floats used to sustain our observations of this dynamic underwater world.

Dr Donnelly is also the organizer of Kirkby SciBar.

10th May 2021 (Zoom 7pm) – Just a Second/Ancient Light

It’s two for the price of one in May, when Dr Steve Barrett returns to give two short talks: Just a Second, in which Steve explores what can happen in one second, and explains why we need leap seconds; plus Ancient Light: Large telescopes have imaged galaxies that are billions of light-years distant. Is it possible to capture an image of one of these very remote objects without a telescope? Steve alluded to this in the talk he gave in March when he referred to photographing objects travelling faster then the speed of light.

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

Following on from Steve’s very entertaining talks on the 10th May, he kindly sent the following information:

You can download handouts of the slides of Steve’s talks here:

And video recordings of the talks are here:

Ancient Light: https://stream.liv.ac.uk/s/8sq82hf6

And if anybody wants to have a think about the weird situation of light travelling through space that is expanding faster than light, here’s an analogy with a person swimming through water that is flowing faster than they can swim:

Steve suggests that it takes a few minutes of quiet thought with a cup of tea for people to get their head around this rather unintuitive concept (the website administrator certainly found that a couple of cans of Brewdog did NOT help!).
