Science and Technology
Until further notice, all our future meetings will be held by Zoom. ( It has been found useful to suggest to each speaker that they have a trial run of Zoom about a week in advance. This is especially useful if they have never used Zoom before. It needs only two or three people to take part for 10 minutes or so and it is useful if one of these has previously used Zoom for a presentation - that person can guide the speaker into the use of Zoom).
A REVISED PROGRAMME FOR THIS YEAR IS SHOWN BELOW
On 25 November Prof Richard Lacey will give a talk on 'The Physics of Security Systems' Dick Lacey is the former chief scientist for CBRNE at the Home Office Scientific Development Branch. He has a background in security systems and is a visiting professor at UCL.
U3A members interested in joining the Group should contact Roger Ball
A visit and speakers for much of 2021 have been arranged but there are still three months spare: May, July and November. So please either volunteer to give a talk or suggest someone who may do so.

While we may not be able to have any live meetings for the foreseeable future you do not have to give up on learning about science and technology! You may wish to visit: Royal Institution Videos (https://www.youtube.com/user/TheRoyalInstitution) Here you will find a great many lectures on various science subjects all in a very easy to understand format. Just skip through any adverts that may come at the start of any lecture.
The Rutherford Appleton Laboratory has a range of free resources for science learning. Click here: RAL Resources for details and links. A list of their forthcoming events, including their fascinating free Talking Science talks, can be found here RAL Events
OBJECTIVES OF THE GROUP
The objectives of the Science & Technology Group (the S&T Group) are:
- to cover a wide range of scientific and technical matters
- to appeal to members who have some scientific or technical qualification and/or experience, at whatever level
- to appeal to members who know nothing scientific or technical, but are willing to have their minds stretched and learn something new and different.
The group meets at 10.00am on the 4th Wednesday of each month except December and (sometimes) August. Currently the group meets in the Radford room at the Methodist Church complex in High St. Witney. There is a break at about 11am for coffee and the meeting closes at around 12.15. After this some members go for a simple lunch locally. There is a charge of £2.00 to pay for the room but sometimes the meeting is "free" if sufficient funds have accumulated.
The group is open to all members of Witney U3A and ladies are especially invited to join in order to provide a more balanced membership and give different views on the topics discussed.
FORMAT OF MEETINGS
Normally the speaker is a member of the Group but once or twice each year it is usually possible to engage an outside speaker.
Once or twice each year there is a visit to a place of interest and members pay for a coach and an entrance fee if required.
On 28th October Graham May gave us a talk entitled "Forecasting: Art or Science?" Graham described the difficuly in providing accurate accurate forecasts and the complexity of the models often needed to provide the results.
In the past year or two there have been presentations on such varied subjects as:
- Stealth aircraft and how they avoid radar detection
- Modern technology applied to brewing
- Gene editing
Visits have been made to:
- The Bristol Aerospace museum
- Bletchley Park
- A satellite tracking station
- The BMW Mini plant at Cowley
On 25th September we visited the Cotswold Distillery. Tucked away, just over the Warwickshire border, the Distillery is another award winning enterprise producing both gin and whiskey. Gin is apparently enjoying great popularity at the moment and is no longer the drink your granny occasionally imbibed. A lot of care is taken in the blending of botanicals to give distinctive flavours. Cotswold whiskey is made from locally grown grain and is matured in barrels from France and Spain for at least 3 years and one day. This is the minimum legal requirement for whiskey although most is matured for far longer. Incidentally there was a Spanish lorry unloading old sherry barrels whilst we were there! The distillery boasts a superb cafe so after an exhausting ‘scientific’ tour we all enjoyed an excellent lunch. Oh, and yes, there was tasting of both gin and whiskey with the distillery providing take away samples for the drivers. As someone was heard to comment, ‘This is the best take-away I’ve ever had’.
