Oak Ridge, Tennessee, was founded as a secret nuclear research facility for the Manhattan Project. My mother's family lived in East Tennessee already, and my grandfather got a job as a day laborer in Oak Ridge. He didn't ask questions, because people who asked a lot of questions didn't last long there. -via Digg
If you're interested in the history of Oak Ridge, you might want to read the story of John Hendrix, a mystic from East Tennessee who died in 1915. The story is not quite as believable as the video above, but it is interesting.
I had a chemistry professor who was in charge of judging the purity of Uranium isotopes after the centrifuges of Oak Ridge. He described in detail how it was done.
A brilliant chemist one told me at a ACS meeting how he invented a jet fuel that allowed planes to fly at 70,000+. I now know the source of "Chem Trails."
My experience is that such information is freely available. Not many people will understand and appreciate. These are just few cases where I could. How many more did I miss?
