New Scientist Live
Saturday 12th to Monday 14th October 2024
New Scientist Live, held annually at ExCeL in London, has become a regular part of our outreach programme. It attracts a much larger number of visitors than any of our other outreach events, over 26,000 this year.
Robert Ratford organised our stand and was there on all three days, supported by other Quekett members Gordon Brown, Kelvin Law, Stephen Parker, Chris Thomas and Alan Wood.
We had a large number of visitors over the three days of the festival, including crowds of children, families, scientists and retired people. We hope that some of them will come to meetings, excursions or outreach events, or join the Club, the Anglian Microscopy Group or the Milton Microscopy Group.
We aimed to engage children, and so most of our microscopes were small Elikliv digital microscopes with a built-in screen; these are available from sources such as Amazon, eBay and AliExpress.

We also had a few full-size microscopes, although they had to be guarded against careless users or tucked away behind monitors.
Stephen Parker brought a polarising microscope so that he could demonstrate the different colours that polarised light can produce in very thin (30µm) section of rocks such as granite and diorite.

Gordon Brown brought a Vision Engineering stereomicroscope that he has repaired and restored, to show images of pseudoscorpions and foraminiferous sand on a monitor

He brought some dry grass from his compost heap, which he knows contains pseudoscorpions, and a laboratory sieve with a 2 mm mesh. He invited visitors to shake the sieve hard to separate the pseudoscorpions and small particles. He then used a small, dampened brush to pick up the pseudoscorpions and transfer them to a small coin capsule so that we could watch them on a monitor.

The pseudoscorpions are very small, as you can see in this photo of one on an adult hand:

Gordon used the stereomicroscope to show forams in sand from
Swanage and Portland Harbour, and microfossils from the Coralline Crag bed
at Ramsholt in Suffolk.

Gordon brought copies of the FSC Illustrated key to the British false scorpions (pseudoscorpions) so that we could see the variety of species that are found in this country.
Gordon also brought a binocular Wild M11 compound microscope with an eyepiece camera sending images of pollen and histology slides to a monitor.

Gordon brought two books with illustrations of pollen, one with coloured SEM images (Pollen: The Hidden Sexuality of Flowers by Madeline Harley & Rob Kesseler), and the other with drawings by Norman Chapman in his book Pollen Microscopy.
Chris Thomas used a black and chrome monocular microscope fitted with an eyepiece camera to show images of a variety of slides on his laptop computer.

Robert Ratford provided a huge variety of specimens, including some living ones, that could be viewed under the small digital microscopes.

To attract visitors from a distance, Robert used an old Epson video projector to display images of brine shrimps and bloodworms from a Chinese inspection camera on the backdrop of our stand.

After the crowds of families had left, we had some unusual visitors.

A few other stands were using optical microscopes.
The Royal College of Veterinary Surgeons had a trinocular compound microscope with a Chinese inspection camera sending images to a monitor.

Bristol Applied Sciences used a Ceti stereomicroscope to show specimens.

The Royal Entomological Society used two GXMXTL3 stereomicroscopes to show insects on slides and embedded in resin to lots of children.

DuraLab were showing the monocular DR-510 compound microscope that they sell.

We have already booked a stand at New Scientist Live next year, Saturday 18th to Monday 20th October 2025.
