Science & Technology

This Group is for anyone with a general interest in science and technology (and their histories). Most sessions will be “study and discuss”: either one person presenting a topic they are familiar with, or several members introducing short reviews of scientific interest stories from the media. We will tackle everything from the science of everyday to some of those big tricky questions. We aim to have at least one visit per term to one of the many science / technology related sites in London.

Frequency : Monthly
When : First Thursday, 2 p.m. for 2.30 p.m. to 3.30 p.m., including tea
Where : Wolseley Road, N8

Group Convener : Clare Smallman

Topic reports

1 March 2018 : Alan Whitehouse – Communicating science ideas to busy MPs

Well that was worth it“, was the parting comment from one of the group. March did its lion thing and most of the group braved the snow to listen to Alan Whitehouse share his experience of communicating science ideas to busy MPs. We were introduced to the the informal / formal and written/verbal processes which strive to ensure our law makers are adequately informed. Alan’s illustrations rang bells and triggered an interested discussion. Another excellent session.

1 February 2018 : Georgina Frost – Design follow up to Wellcome visit

Georgina Frost led our discussion with a summary of the “Can Graphic Design Save your Life?” exhibition at the at the Wellcome Collection, and prompted debate with well placed questions. Many of the group had visited the exhibition and the discussion was wide ranging and thoughtful. A most enjoyable session.


“I didn’t think I was going to be interested in acoustics last time or graphics this time” said a group member as she left the February meeting. “I was wrong twice.”

4 January 2018 : Jon Raper – Acoustics in Public Places or Why Some Restaurants are Hell

Here is Jon surrounded by bags of materials which can help improve the acoustics of public spaces. He took us through sound management basics, problems for professional acousticians, and specific issues (and options) for restaurants and concert halls. We had a “handling session”, the backgrounds to several problem buildings in London (“Oh that’s why….”), and a very lively discussion. I shall never look at a restaurant the same way again.

7 December 2017 : Mike Holmes – Why Trees are the Wrong Colour

At the SIG’s first fascinating discussion, Mike Holmes topped and tailed his talk “Why Trees Are The Wrong Colour” with a review of the way memes and gene have similar longevity and unintended consequences. The “meme” story was the crazy size limitation of so many objects to 4 ft 8 1/2 inches wide. We followed links back through rail tracks, farm carts and rutted roads to the Romans and their enthusiasm for easily replaceable standard parts. The “gene” story pointed out that plants should be black or at least purple to absorb the most energy. Instead most absorb blue and red light and reflect the green / yellow higher energy wavelengths. Mike took us back to the origins of life on earth. Bacteria made an initial breakthrough using yellow / green light, “and the seas turned purple”. Others had to manage on the light that made it through the haze. They stumbled on chlorophyll which had extra potential and some serious side effects. When the various subsequent disasters cleared, the winners on land had green pigment inherited from their ancestors.
