150th anniversary of Guglielmo Marconi

25 April 2024 is the 150th anniversary of the birth of Guglielmo Marconi, inventor of radio and to whom the city of Chelmsford owes much of its industrial heritage.

Marconi set up the first factory for his Wireless Telegraph & Signal Company in Hall Street, Chelmsford in 1898. The work that took place there (and other sites subsequently) changed the world, completely revolutionising how we communicate with each other, entertain the population and sense the world around us. Find out more by reading this BBC article by CSES member Tim Wander.

The history of CSES, which had its centenary in 2020, is closely linked to the history of the Marconi Company. In its earliest days, the society was a meeting of engineers from the major companies based in Chelmsford, including Marconi's. You can read more about our history here.

We mark this occasion in collaboration with the Museo Marconi, Bologna, Italy, who are holding a special celebration event, further details of which can be found here.

Centenary Photographic Competition 2024: Time

For Primary and Secondary Students

Taking a camera or your phone and shooting a picture is an easy. But how about, when composing your image, you think about how your picture might be used to discover some aspect of science and engineering?

STEAM: Science, Technology, Engineering, Arts, MathematicsFrom your camera or mobile phone to a flower or a rainbow, from a bubble to radio mast, from smoke to light, from microscopy to astronomy, everywhere in our modern world we are facing science and engineering wonders that make our lives easier and more fun. This is the fifth year of our competition and we have had some outstanding winners.

Science meets Art – Our annual photographic competition aims at creating an opportunity for you to creatively express what you observe within science, in pictures, and we hope that this will get you to explore the visual aspects of STEAM through the art and science of photography and capture images that demonstrate and communicate STEAM concepts and phenomena.

This year 2024,

the focus of the competition is on:


(Including everything from clocks, hourglasses, sundials to biological clocks, sunsets, stars, ancient monuments and more!)

We want you to take photographs (up to 3 entries per person) that express what Time means to you or how it impacts health or our environment, including the negative or positive roles of technology. Each photograph must be accompanied with a short plain language explanation (not more than 50 words) of the thoughts behind your photograph.

Urgently seeking new CSES Secretary

Are you looking for a flexible, low-commitment way to get more involved in the work of CSES and promoting STEM more generally? Do you have a couple of hours you could spare each month?

If so, then the role of CSES Secretary could be for you. We are urgently seeking candidates to fill this vital position. Please do consider putting yourself forward.

The formal role has a few key responsibilities with a very low time commitment (some more details on this below), but you would be able to take part in and volunteer for other activities organised by CSES if you wish, such as the Science Festival, TEXPO, Saturday Club and events in schools.
