Tech and science – Prussian blue

Our talk on Wednesday will cover the chemistry and science of various compounds that lead from artificial colours to poison gases. Interested?   Come along for a hopefully enlightening presentation.

Bowland in September

Undeterred by Yellow Weather Warnings, 6 Ramblers set off from the lovely village of Bowland by Bowland for a 10 mile circular walk. The weather was fine and dry when we set off but we were realistic that this might not last!

After the first leg to the village of Sawley, we had a quick water stop and a photo op alongside the River Ribble. A couple of miles further on we stopped for lunch in a very odd location which comprised a Stone Circle and Arthurian sword in the stone!<

A heavy downpour caught us out, so shelter under some trees proved a good idea except for the multitude of very liquid cow pats! Moving on we crossed a small plateau before dropping down to the river along a steep and partially stepped path.

The final stretch took us through the village Bolton in Bowland and back to Bowland car park for a quick change before the short drive to Sawley and a welcome drink in the Spread Eagle pub.

T+S does Plague

Our Technology and Science group looked at the history and science of ‘plague’ at the end of June. We covered several pandemics around the world but, because the presenter is squeamish, the gory details were only scraped over.

But Channel 5 has given us the chance to relive the 1665 English events.

Tech Group visits Grenfell

Wednesday’s talk was given by John Joyce (BA) who talked about all aspects of the Grenfell Towers incident. A very comprehensive presentation covered the incident itself, previous issues with similar buildings, building materials, council  issues and the inquiry.

He also gave detailed information on the outcomes of findings within all the industries and services involved including significant changes to legislation, likely to affect all construction in the future.

The presentation was broken down into 5 key areas:

  • Grenfell summary
  • Construction sector
  • BSA summary
  • Grenfell today
  • What next for the fire industry ?

Our thanks to John and to Steve for inviting him to the group.

Next month we will be looking at Luca Turin (11th) and plague (25th)
