We too visit science museums, locations of discoveries (with plaques in the UK) and homes of scientists when we travel. Over several trips to the Deutches Museum in Munich we’ve not seen it all but tried to find the collections that interested us that day.
We also like the History of Science Museum in Oxford. https://www.hsm.ox.ac.uk/. I was more fond of the Galileo Museum in Florence before it’s modernization. I’m hoping to see this summer that the Mendel Museum at the Monastery in Brno has improved, at least in its signage, since our only visit in 1998. I hope we can still walk in the pea garden.
My favorite home to visit was Charles Darwin’s Down House. Getting there required a train and taxi from London but it was a fantastic discovery. We were able to walk the Sand Walk in the garden and wander through the rooms that reflected a very active and curious family life.
Walking into Marie Curie’s lab in 2019 gave me chills.
My husband is the scientist in our family but I’ve enjoyed all of the museums and homes we’ve been to. I hope you enjoy some of the many suggestions mentioned above by these wonderful forum members too.
