I have mentioned this whenever they have their yearly open Summer Sundays. If you are anywhere near Long Island, NY, you really shouldn't miss the opportunity to visit Brookhaven National Laboratory during one of their Summer Sundays. You get to visit not only the lab in general, but also get to tour the facility that's open for visitors for that day. Typically, the days highlighting the NSLS and RHIC are two of the more popular and tend to have the largest number of visitors, and understandably so.
This is one of the few opportunities one gets to tour a world class science facility and gets to ask questions to scientists working there.
Speaking of Brookhaven, it seems that people are still publishing erroneous rumors and accusation towards the lab that are amazingly wrong (and presumably getting away with it). The lab wisely decided to address the inaccuracies published in a book titled "SWelcome to Shirley: A Memoir from an Atomic Town", and included references to the affect of the lab on that two and the surrounding area on Long Island. It is amazing that someone would publish a book and yet, hardly do any homework on what they are writing on. Unfortunately, many of the book's readers would probably never see these counter points against the book and so, these inaccuracies (lies?) will be perpetuated. This is usually the "source" of information for the "public" and these accusations are taken as gospel by many.
