math solution, fyi
If you have Excel, here is the solution to a problem involving vectors: http://mypeoplepc.com/members/jon8338/sitebuildercontent/sitebuilderfiles/triangulation00.xls You input the lengths of three lines and their starting coordinates, and the engine calculates where they intersect ( in three dimensions). I s... 12 Jun 2010 11:33

SOLAR ENERGY MAY SOON GET MUCH CHEAPER
Solar Energy May Soon Get Much Cheaper By Brian Westenhaus oilprice.com Thursday, June 10, 2010 Scientists from the California Institute of Technology (Caltech) have developed a new solar cell that they hope will cost a tiny fraction of current production. The new cells consist of tiny silicon wires that ... 14 Jun 2010 10:39

neutrino oscillation
is the key understanding this process requires an intense sense of imagination going in contrast with extensive experimental research. just like organic chemistry is an entire field because of the complex structures the :(.C.): atom can create (all the way up to life) neutrinos will have an entire field bec... 28 Jun 2010 17:17

Reality
There is a space filling medium. It is capable of motion and resilience. It exerts an expansive pressure in all directions. It is but a small step from there to the recognition that this very same material substance is what is formed into the atoms and molecules of gross matter. To take that step, however, a vast... 23 Jun 2010 23:54

Wegener's Continental Drift theory may be telling on Atom Totality social acceptance Chapt 1 &3 #155; ATOM TOTALITY
Well I really do not much care of the socialization of a theory of science. In some cases the public social acceptance of a science truth may take milleniums as for the case of heliocentric versus geocentric solar system. For me personally, to know the truth of what is true and what is false is enough satisfactio... 11 Jun 2010 15:55

1100m below the ground - two interview videos
There can't be many physicists whose job involves travelling to the bottom of a deep mine shaft wearing a day-glo jacket and a hard hat, and then trying to coax a bespoke detector into spotting something - without even knowing what it might be. But that's exactly the task for researchers at the Boulby Undergro... 20 Jun 2010 12:22

More than 90 percent of objects found in the vast outer-solar system reservoir may have been born around other stars
Brad Guth wrote: Sirius(B) is the only seriously big one of up to 9 solar mass that went nova(helium flashover), as well as having lost its tidal radii grip on its planets and their moons upon collapsing from its red supergiant phase as of a little more than 65 million years BP. The original Sirius st... 19 Jun 2010 13:28
