How about some engineering?
There is a museum in London showing the work of one Isambard Kingdom Brunel. An engineer ahead of his time. He built stunning bridges, railway lines and all infrastructure connected (including Paddington Station, just 5 minutes from the hotel) and first underwater tunnel (still used today, by London Overground).
If your mind leans towards the technical side of things, Brunel Museum is definitely a place for you to visit.
