Science and Technology

Last Updated: Wednesday, 16 May 2018

The objective of this group is to study the fields and innovations associated with everyday Science and Technology. Where possible, in depth studies of particular areas of interest will be encouraged amongst the members of the group but no areas should be deemed beyond the scope of the group. It is hoped we can come to understand how some technology, common to our daily lives works and the science behind their invention or discovery. Any member who has a specialist knowledge would be encouraged to share that knowledge.

We will be making visits to technology presentations and museums, local science fairs and businesses where possible. Presentations and demonstrations from others outside the U3A will be arranged.

Here are some areas of Science and or Technology we'll be looking at:

The list is endless.

Meetings are held on the FOURTH Friday in the month, usually in the small hall at the rear of the Methodist Church, Station Road Chinnor at 2pm until 4pm. Please enter via the door at the left side of the building.

Parking at the church is extremely limited (2 cars maximum) so you will either need to walk or park close by. The nearest public car park is outside the doctors surgery, opposite the new pavilion. Parking on Station Road is not advised as it is a very busy road.

If anyone is interested in joining, please fill in the form at the bottom of the page and we'll be in touch.

NB. Currently the group is in flux and not meeting regularly as I have had some medical issues. Please get in touch and I'll tell you when we meet next.

First Meeting

The Inaugural meeting of the new Science and Technology Group, took place on Tuesday 28th March 2017.

We discussed the groups aims and what members would like to get from the group, the consensus was the understanding of Technology in use today. Also, it was put forward that we might collaborate on a document giving the history of the progress in technology, as many members remember when things were very different. 

Following the dscussions, Chas gave a presentation into 'How Microwave Ovens Work', which was well appreciated..


Second Meeting

Our second meeting was held on Thursday 28th April and was well attended. We watched a video about new advances in Bionics and you can view it yourselves below or on YouTube.

Hugh Herr gives a fascinating talk about Bionics and the improvements he has designed. Followed by another look at how Bionics have been developed.

Chas followed the video with a presentation on how Audio is recorded digitally, how it is put onto a CD, the manufacturing of the CD and how a CD player reads the data back for reproduction into sound.

Videos of this and the Microwave Oven presentation will be available soon.


Third Meeting

On one of the hottest days of the year so far, we met once again in the small hall of the Chinnor Methodist Church. We discussed the Science Fair being held in Oxford during 14th to the 21st June, See here for details.
We welcomed three new members to the group and talked about what they want from and what they can contribute to the group. We had then planned to watch a big screen movie about going to mars, see below, but sadly the projector once again let us down (Chas to try and fix once more), so it turned out to be a small screen movie.

 

Following the film and a cuppa tea, we then moved on to the Fun Quiz, I had produced. Being a clever clogs, I did it on a PowerPoint template, however, after the first three questions had been shown, I realised that all the correct answers were A. We continued and everyone marked their answer paper accordingly, then when we started to go through the answers, it became apparent that the answer slided didn't match the question slides, so I owned up to a grave error, I DIDN'T TEST the presentation fully. Copy and paste of the slides had reset them. Anyway, we had a good laugh about it and proceeded to discuss the answers. In the end, two members had both scored EIGHT points and Peter graciously allowed Pete to receive the small prize I had brought, a small USB memory stick.

So, if you want to try your hand at the quiz, you can do so by clicking the image below and viewing the (now fixed) Powerpoint on the web.

Fourth Meeting - How Violins are made - A Presentation by Pete Honeyball.

20170728 142551Pete turned up with boxes of bits of wood, but where were the hammer and nails? No need for brute force he said, it's all held together with glue.

Showing us how the wood was chosen and marked with a template, Pete continued with the tools and skills necessary to create a musical instrument used by thousands for many years. The basic concept has remained the same since they were first invented. The "Decorative" lines were in fact purling lines, used to protect the edges of the expensive wood and allowing for repairs to be made much easier. Forming the neck was a long laborious task and Pete showed us one which wasnt quite right. 

All in all a fascinating demonstration of the fine art of Viloin maker. Pete finished off by showing us "One he had made earlier" dedicated to his wife Jane and proceeded to demonstrate that he wasn't a Violin player 😄

 Here are some other photos from the presentation, showing the tools and wood used.

A visit to the Rutherford Appleton Laboratories.

10th August 2017.

Four of our group were able to visit this fascinating campus of Science and Technology, located at Harwell near Oxford. The campus is huge and is run by the Science and Technology Facilities Council. Once we found our way to reception we were ushered into a huge lecture theatre. Here we were presented with a fascinating lecture by Paul Eccleston on Exoplanets and the forthcoming ARIEL space telescope mission. Here we learned about how many plaets there are in the Galaxy (more than the grains of sand on the planet Earth!), How these planets are discovered, the methods for detecting them and the way in which the ARIEL telescope will be used after it is launched in 2026.

Once the lecture concluded, we split into several tour groups to visit some of the facilities. There are too many to attend in one day so we hope to make future trips to see them all. The tour options include:

Three of us visited the Visualisation and Scientific Computing departments and one of us visited the Vucan Laser control room.

There were plenty of opportunities to take photos but the tour presentations were so interesting I forgot to get my camera out. However, during the walk through the scientific computing section, we visited the data storage and processing areas. The air conditioning was very noisy so we had to wear ear defenders and of course, couldn't communicate. So here I was able to take some snaps of our group in between some of the computer racks.

All in all a very interesting outing. To find out more about the STFC and even visit yourself, please visit the STFC website.
