The Smithsonian Associates is the largest museum-based educational program in the world. They offer over 750 events in a calendar year: workshops, tours, lectures, performances, summer camps etc.
My educational guru, Susan Wise Bauer, will be lecturing there on December 5, about one of her books – The Story of Western Science. I have read the book and learned a lot from it. I highly recommend it. It will give you an overview of the scientific themes humanity grappled with over the centuries. The book also contains enough details about each important scientific manuscript to help you understand specific topics.
