"A 14-year-old Dalit boy, born and brought up in a remote village of western Uttar Pradesh, has suddenly turned angrez . Rajesh, without any evident help, has started speaking fluently in English and does so with a proper American drawl. And that’s not all: He seems to have forgotten how to speak Hindi.
Wonders do not cease with this: His knowledge of physics and mathematics has left engineering students baffled. Having already penned three books, Rajesh is now looking forward to some research work. "I did not take him seriously for a few months but on Republic Day, while the students were reciting poetry before the entire college, Rajesh took the mike and addressed the gathering in fluent English. This left us almost shell-shocked," says Shishu Pal. Rajesh’s mother Omkali and 16-year-old brother Kaluwa are daily wage labourers who earn just enough to manage two square meals a day. His father Sompal is mentally-challenged." Times of India

WOW: What theory could explain this?!

If anything in the vacuum of space that was set into motion will travel at the same rate of speed constantly as the initial thrust, could light speed happen by an engine that was constantly pushing the object?

Would the speed of the object be grow exponentially faster by the second? Could speeds greater than that of Light also manifest?

Have an old PC switching power supply with a component labeled DA1 in its circuit board. Can anyone tell me what it is? It looks like a glass enclosed, small signal diode but with only a black band around its middle, not at one end such as a diode would have. I assume it's not a diode as elsewhere on the board there are other components I see as diodes which have a marking band around only one end, they are labeled D1, D2, D3, etc., and the board markings indicate which way these parts should be oriented on the board. The markings for DA1 do not indicate any such orientation, as would be necessary if it were some kind of diode. Might anyone know what this part is?

The switching supply seems to work only every umpteenth time power is applied to it, and the DA1 component's location in the circuit appears related to the main switching circuit's initial starting drive for before the main regulation pulse width feedback loop gets going. Identifying its function seems important.

I have been reading about a polar shift of 45 degrees because of the planets alignment with the sun in 2012.This only happens every 25,000 yr. or so. Also this date is the end of the Mayan calendar,and the return of planet x crossing our path in the solar system. To me it seems the way the world is going everything in life is at full circle. And the world is way over due for some type of renewal threw a natural cataclysmic event !
