The ATOM Science Festival was on today and included about twenty interactive stalls on Abingdon Market Place.

The Science Market included many companies with local facilities. This company was demonstrating how some chemicals grow into crystals. They research and develop chemical compounds that treat disease.

This company was demonstrating how the PH or acidity of a liquid could be changed by adding dry ice.

One Planet Abingdon was there, warning of the climate crisis and giving people practical steps to help. They had a pledge bag where people could pick out a pledge somebody had left and then leave another for somebody else.

This stall was a Science education company and had lots of interactive activities.

There were also activities in the museum and talks at the Guildhall.

A two-part talk was at the Amey Theatre at Abingdon School in the evening. David Miles spoke about some of the forgotten heroes in the development of vaccines.

Then Professor Frank Close spoke on the discovery of the Higgs field and the Higgs Boson particle. Peter Higgs (and others) proposed the existence of the field and particle in 1964, which was demonstrated by the CERN particle accelerator in 2012.  Professor Close has written a book, Elusive, which details the elusive Higgs Boson particle that is behind the Higgs field, and the elusive character of Peter Higgs, who went missing when it was announced he had won the Nobel Prize in 2013. (As I understand it, the movement of elementary particles, such as electrons and quarks, through the Higgs field gives such particles mass, without which they could not combine to make atoms. Higgs Boson particles are behind the Higgs field and have been detetected by smashing particles at CERN to produce very high temperatures.)

There is a further talk on Wednesday by Professor Jim Al Khalili. See https://www.atomfestival.org.uk/2023-programme/.

It was announced two days ago that the JET tokamak, at Culham near Abingdon, produced two and a half times the amount of fusion energy obtained during a previous trial in 1997. It provides test evidence that the more advanced tokamak, called ITER, being built in the South of France, is worthwhile.

JET’s tokamak reactor has atoms of deuterium and tritium at the center. These isotopes of hydrogen (having one and two additional neutrons respectively), are heated to temperatures (10 x the Sun’s centre) to fuse them into helium atoms. This reaction releases a huge amount of energy.

The picture from Abingdon Museum has some information about atomic research happening at Harwell and Culham.

There was a stall on the Market Place to let us all know that there is a science trail with 24 locations in Abingdon-on-Thames. At each location you can do an activity using a smart phone or tablet.

You can download the app from https://www.atomfestival.org.uk . It has a map. At each location on the map is a QR code the app can scan and launch one of the virtual activities.

At the Abingdon Millennium Needle, for example, the virtual activity involves watching a video from the Jenner Institute and then answering a couple of questions on Cells and vaccines.

The trail is available from 11th – 13th June 2021. Lots of different organizations have provided the virtual Science lessons, and donated prizes for the best answers.

The hash tag #ATOM2021 is being on social media to share pictures about the Science trail.
