This was a talk in person by Jeremy Batch. A synopsis of the presentation is given below.
Swinging, Spinning and Wobbling: pendulums, gyroscopes and Inertial
Navigation – a talk by Jeremy Batch
“I can dive off the eastern coast of the United States and surface again in the Mediterranean within five hundred yards of where I expect to be,” says Rock Hudson to Patrick McGoohan in Ice Station Zebra. We would take that for granted today, but how was it even imaginable in 1963 when Alistair Maclean wrote the book, and was the captain (or the author) exaggerating?
Our world is round (sort-of) and takes 24 hours (almost) to revolve. The roundness was
obvious to sailors for centuries, but the size of the sphere (if, indeed, it was a sphere) was a matter of guesswork and its rotation was once a dangerous heresy. The tilt, wobble and lumpy shape were all puzzling, but eventually undeniable.
We shall meet: Léon Foucault, demonstrating the Earth’s rotation with pendulums and gyroscopes which stay fixed relative to the universe; Hermann Anschütz-Kaempfe, using the rotation to align his gyrocompass, and Elmer Sperry (allegedly) copying his ideas; leading to Charles Stark Draper and his rivals developing inertial navigation for ships, submarines, missiles, aircraft, spacecraft and cars, allowing us to travel confidently to the Moon and across its surface and (more daringly) beneath the North Polar icecap and through the Limehouse Link tunnel.
And as the Royal Navy tests Birmingham University’s quantum inertial navigation system on XVPatrick Blackett, ready for when GPS says “0 satellites available”, should we be saving our pennies or polishing our sextants?
This was a well attended meeting and the audience look forward to seeing future presentations from Jeremy. We will try to book Jeremy for a future presentation in 2025.
This event was scheduled so we could celebrate that March 2024 was both the 200th anniversary of RNLI’s formation and the 40th anniversary of SOCA being formed. The planned presentation on the RNLI had to be delayed to another time due to the presenter being ill, (he has offered to conduct his presentation at a later time). However in its place SOCA held a RNLI themed evening for its September meeting, including showing some videos available on the RNLI website and a few group quizzes,
The main part of the evening was a presentation of a cheque to the Chairman of the RNLI Hitchin & District Branch of the RNLI, John Pearce. The majority of the £260 that was donated was from donations from individual members with a top up from the Commodore’s charity fund. After the actual cheque, (rather than the one in the picture) was handed over John gave a quick speech to the audience highlighting the difficulties that the local branches of the RNLI have had in recent years with falling numbers of people able to organise events that can be used for collecting donations. He made a plea for anyone who is interested and can help to contact him. (pearcej53@virginmedia.com).

This is traditionally our biggest fundraising event of the year and this year will be extra special as we celebrate two hundred years since the founding of the RNLI. We would really like to make this year special and as usual we shall have stalls in the Market Square selling a range of RNLI branded merchandise including our ever popular Christmas Cards, Diaries and Calendars as well as bric a brac.
We hope very much to see you there. This year we are hoping to place as many street collectors around the town as possible during the day and if you are able to spare an hour or longer holding a collection bucket please let us know your preferred time and I will put together a rota with full details closer to the time. If you prefer to help on a stall, please also let us know as we may have need of a little help during the day.”

This was, a very informative and enjoyable presentation about a trip to Antarctica and the Falkland Islands, the talk complemented Dave’s talk last year that was based on a visit to the other end of the earth In Search of the Northern Lights, will confirm. The presentation included some stunning photographs from the Southern Ocean. a couple of examples are shown below,
Antarctica and the Falkland Islands.
In February 2023, keen photographers Liz and Dave Arnold went on a cruise to Antarctica and the Falkland Islands. With stunning landscapes, unique wildlife and historic locations, Dave will present the best from the voyage, together with information about the geography, and some of the major events and politics which have kept Antarctica in its pristine wilderness state.
Despite some technical issues (with sound quality) when we tried to conduct a joint, in person and ZOOM, meeting the club did eventually manage to successfully hod the 2024 AGM which again was a relaxed, social evening which gave the retiring Commodore, Andrew, the chance to look back at the past year and for the new Commodore to discuss plans for the next season.

RNLI Hitchin & District Branch Events Planned for 2024
Dear Supporter
I hope you have an enjoyable and relaxing Easter break. I am pleased to let you know that as the days grow longer (and hopefully warmer) we have arranged our first fundraising event of the year. Morrisons Supermarket in Letchworth have kindly allowed us to collect there on Saturday the 20th and Sunday the 21st April. In previous years the collection was indoors behind the tills and near the carpark entrance and I expect that this will be the case again this year.
If you are able to spare an hour or two to hold a bucket to help raise funds for our RNLI volunteers saving lives at sea on either day between 10.00 am and 4.00 pm would you please let me know your preferred date and times as early as possible. I will then draw up rotas for each day and circulate them to the volunteers with full details closer to the time.
