Website technical issues

Update 3 July: Functionality for online registration is restored. There is still an issue with the generation of links in some automated emails (especially event reminders), which we are continuing to investigate with the software developers. A fix should be in place for the start of the 2022-2023 events programme.

Update 15 July: We have had to migrate the server on an emergency basis to a new facility. Users should notice no change, and everything appears to be working as normal, but please advise if there are any issues.

If you experience any issues using the website, please Contact the Webmaster (technical support) with any relevant screenshots and the exact date/time that the problem occurred.

Thank you for your patience.

Chelmsford Innovation: Marconi and Beyond

Chelmsford Innovation: Marconi and Beyond

A special exhibition showcasing innovation from the last 100 years to the present day

Chelmsford has been a world-renowned centre of scientific and technological innovation for well over 100 years, and still is today. Among other things, Chelmsford is home to the world's first wireless (later radio) factory, the world's first river water treatment plant and the world's first colour digital camera – and that's just from within the last century. Today, companies in Chelmsford continue to build the technology of the future, with high-tech developments in fields as diverse as space, medicine, communications and defence. The impact of industry in Chelmsford on all of our lives is incredible.

A collaboration between ARU, CSES, Chelmsford Civic Society and the Marconi Veterans' Association, this exhibition will tell a part of that story, revealing how household names such as Marconi are echoed in the modern age. It will take place in ARU's Marconi building, which was opened by Princess Elettra Marconi Giovanelli, the daughter of Guglielmo Marconi, in 2010, on ARU's Chelmsford campus.

The exhibition will open on Wednesday, 22 June and will run on specific days until Friday, 15 July. Attendees need to book their place – more information and full details of times can be found at https://www.eventbrite.co.uk/e/chelmsford-innovation-marconi-and-beyond-tickets-324804377637.

CSES Curry Evening to celebrate 2MT/BBC Centenary

CSES Curry Evening to celebrate 2MT/BBC Centenary

Monday 23 May 2022, Pakwaan Indian Punjabi Cuisine, Writtle

Click here to book your place(s).

Members and guests are invited to join us to celebrate 100 years since radio broadcasting first began in Writtle.

Did you know that the world's first radio station started in Writtle in 1922? Called 2MT ("Two Emma Toc"), this humble – and somewhat experimental – enterprise operating from a small hut ultimately became the BBC as we know it today.

Exactly 100 years ago, Marconi Company engineers sat in the snug of the old Cock and Bell Inn – now the site of the Pakwaan – and planned the first ever scheduled radio broadcasts in the form of concerts to be aired by 2MT. The success of this station, under Captain Peter Eckersley, led directly to the start of the BBC.

We invite you to join us for a special one-off evening to celebrate this significant milestone. Like those Marconi engineers 100 years ago, this is an opportunity to eat, drink, and maybe even change the world...

5pm – History Walk of significant Writtle sites with historians Alan Pamphilon and Tim Wander (meet in the restaurant car park)

7pm – Dinner followed by speech and presentation of commemorative plaque

Click here to see the menu – 1920s dress encouraged!

The restaurant is all ours for the evening with an excellent set menu with all the trimmings to choose from. The after-dinner speaker will be Writtle 2MT and Marconi historian Tim Wander, and a plaque will be presented to the restaurant owners.

Spaces are limited and must be pre-booked by Monday 16 May. Click here to book.

We look forward to seeing you there! Read on for a little more of the story...

International Day of Women and Girls in Science 2022

International Day of Women and Girls in Science 2022

Friday 11 February 2022

One of the major aims of our society is to raise awareness about both the achievements and challenges of science, engineering, and all things technological. As we continue to develop our educational activities, we would we like to ensure that – as far as possible – we link what we do into both the national and global picture.

There are many national and international celebrations, some of which are dedicated to areas of science and engineering; these are occasions designed to educate the public on issues of concern, and to help mobilise political will and resources to address national and global problems.

As we continue to develop our activities, we will try to co-ordinate some of our activities around selected STEM celebrations, either by simply providing information or by organising specific activities to use these as a springboard for raising awareness.

Please think about volunteering to help CSES contribute to or organise an event next year to celebrate:

International Day of Women and Girls in Science, 11 February
