Welcome to our virtual STEM learning programme.
These short videos explain how we are using computing, science, maths and engineering to help people to communicate and stay connected.
We hope these will help to bring the school curriculum to life and give you a view of what you are learning at school or college is used in the world of work.
Why not start with taking a look at our Purposeful Innovation video to find out a little bit more about what we do?
Please email us at with any feedback or if you have an request for a topic you'd like us to cover.
