The CSES organise regular lectures on various Engineering subjects during the winter months, typically starting at 6.30pm or 7pm.
They are usually held in the Chelmsford Anglia Ruskin University (end of New Street), and occasionally Basildon or the Ford Research center at Dunton.
COVID-19 Update: Since the University is now closed, all lectures which are still being held are now on-line using the ZOOM application - for which you need a PC, tablet or smart device.
The lectures are free, but you can join the CSES for £12 per year.
