    George Ellery Hale was an early and important pioneer of Solar Research.  In the early 19th Century, in Pasadena,  coincidently, the present  location of NASA`s…

This first video is where I explain Hilbert Space Tensor Products. I explained Hilbert spaces and operators in a previous video. The sound is not stellar so turn up the volume to the max, and you…

The Solar core is truly dynamic.  It has been jetting twin jets, which are possitioned diametrically opposite each other,  since it formed  some billions of years ago.  These jets…

A few months ago I did a bit of thinking about gravity from a different angle.  I asked the question... How would the equations of classical General Relativity look if Planck Units were used.…

The rotating black hole has been described as one of nature's most perfect objects.  As described by the Kerr solution of Einstein's gravitational field equations, its spacetime geometry is…

In tales, legend and role-playing games, sprites are tiny creatures that cause lots of rascally hijinks - sometimes they even dance in the sky.   Scientists at Tel Aviv University say that some…

Someone on this site recently posed the following thought experiment questioning the postulate of special relativity that no object can travel faster than the speed of light - c.  Imagine a one…

Its a matter of 64 years,  at the close of WW2  since  a few Norwegian Radio Astronomers, first encountered  the CBR.   Continuous searches for intelligent have yeilded…

There is often an uncomfortable and artificial hierarchy amongst theorists and experimentalists.  Those exalting pure theory often forget that applied science is an art unto itself as is…

The Higgs field isn't the only thing the LHC might unearth.  A while back Sean Carroll posted a great discussion of other possibilities including supersymmetry, dark matter and something not yet…
