This is avery useful site an has a book that the site owner wrote
http://www.dcn.davis.ca.us/~welsh/book.htm
That explains about Mindcontrol equipment and black ops experiments that have caused people to be classed as mad and even caused them to do things they wouldn't (Murders, Bombings, Suicides etc)
Google, My personal favourite Search engine at present
http://www.google.com It's help me find a lot of stuff.
Dog Pile
http://www.dogpile.com yes another search engine, which I only mentioned because of the stupid name... still it does tend to come up with the biggest pile of....... possible answers to your search.
http://www.fbi.gov/ I couldn't work out what this was.... No seriously... it's the FBI's website, and the best way of keeping up with particular info, especially with recent events.
Bot Spot
http://www.botspot.com/ So your a budding AI designer, or you want to make your server start serving up spiders to hunt around for the information you desire and email you with the results, Perhaps you want to learn what an agent is so you know how comes your e-mail address is constantly spammed by silly adverts, then perhaps you can find this resource rather useful for answering some of the questions you might face (Including spaghetti logic).
Anti-Mind control Beanie
http://zapatopi.net/afdb.html Yes you too can now wrap your head up in tin foil, and make it that much more easier for people with the right equipment to bake your brain like a potatoe. The idea might be good, as we might need Mind Shields in the future, but I'm not going to say "invention" works, it's gimicky but a fun page to look at.
Universities and Academic Institues
http://www.phy.cam.ac.uk/ Cavendish University in Cambridge. An astronomer's paradise, and quite a few theorists stalking ground.
http://www.cyber.rdg.ac.uk/ Reading Cybernetics, In Reading of course
http://www.lanl.gov/ Los Alamos (Birthplace of Chaos theory supposedly.)
http://www.isis.rl.ac.uk/ a Rutherford Appleton Laboratory at Oxford (well a website with info about Quantum particles etc and the reasearch they do)
http://www.CERN.ch/ If you don't know of CERN then you obviously don't know about the largest particle accelerator. Again another theorists stalking ground.
http://www.ic.ac.uk/ Imperial College in London.
http://www.cst.gov.uk/ Council for Science and Technology, England.
European Space Program

I'll have to kick around some thought into other sites as for now I've forgotten all the best ones (or they've changed their pledges)
