This is particularly true if I include as "the same" those numbers which, as a group, can be seen as having some identifiable pattern. ... Do you really believe that you can construct a set of numbers so large as to have 10^20 numbers in each of the sequenced sets without having that pattern appear somewhere in a large number of those sequenced sets. ... www.astronomy.net . ...
... Plates and Drilling . ... Results . ... In January of 1992 we drilled and measured a set of test plates testing several techniques including drilling with a carbide twist drill and drilling followed by reaming [R. Owen, et al., unpublished]. ... The test plates were 3.5" diameter 1/8" thick disks of aluminum. 50 holes were drilled in each test plate, 10 each in five concentric circles. ... This diameter was the optimal value for our plug plates determined from the 1/92 drilling tests. ...

This year marks the 25th anniversary of shuttle's free-flight tests By Lisa Tidwell ike a child who must learn to walk before running, the space shuttle had to prove it could safely land before it could become NASA's main mode of transportation into space. ... In January 1977, the Enterprise traveled 36 miles over land from Palmdale to the place of its first flight NASA's Dryden Flight Research Facility at Edwards Air Force Base. ... Joseph Fries, NASA Manager of the test facility, agreed. ...
... Mark Jaworsky will present one early next year. ... It is theorized that Dark Matter is responsible for holding galactic (Program, continued on page 3) (Program, continued from page 2) systems together and that without it, galaxy-mass structures just would have not come into existence. ... Researchers use the theory of Dark Matter to explain this discrepancy. ... The standard theory of gravity still applies and dark matter still exists, but somehow the dark matter emulates MOND. ...

... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ...
