Two of them would use proven interferometers, one having already detected absolute speeds.
Modern instruments are introduced, including laser interferometers and AFM's, and there are sections on fractals and motif analysis.
Within the next decade the first submillimetre interferometers will come on-line.
In the next few years, ground-based interferometers will be completed that can image large extrasolar planets.
Such radio interferometers can resolve details far sharper than anything current optical telescopes can see.
