This is a series of four articles each with a separate explanation of different phenomena. Each of the four articles is a piece of a mosaic and so every one is needed to understand the final explanation of the quantum astronomy experiment we will be proposing to do possibly using the Allen Array Telescope and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

One of the things we plan to do different in the Geek Ranch (see What's New Down Here?) is build a lot of domes instead of conventional buildings. The reasoning behind this is that they are quicker to build, cost less and use mostly local materials and that which is not local (in particular, steel) is used in lower quantities than read more

_ 1991: The International Atomic Energy Agency places a seal over storage bunkers holding conventional explosives known as HMX and RDX and PETN at the Al-Qaqaa facility south of Baghdad as part of U.N. sanctions that ordered the dismantlement of Iraq's nuclear program after the Gulf War. HMX is a "dual use" substance powerful enough to ignite the fissile material in an atomic bomb and set off a nuclear chain reaction.
