Write a post here to share your travel experiences and perhaps comment on Traveling with the Atom: A Scientific Guide to Europe and Beyond. Let us know if you did or did not enjoy a site in the book, what changes may have been made at the site, whether you agree with the number of atoms that were assigned to the site, and so forth. (All sites in the book are rated from 1- to 5-atoms based on their perceived appeal to travelers interested in the history of the atomic concept.) Also please feel free to suggest other places that should be added. Here is your chance to exchange information, share experiences, and ask questions of each other and the author.
