Why is the shortest day not in the dead centre of the period of GMT as it must get lighter at the same rate that it got darker.
Why do we have to wait until the end of march before we put our clocks to BST, 93 days after the shortest day. We put our clocks back to GMT 51 days before the shortest day. Why the difference.

From what I understand Pluto was demoted because it was not the dominant body in its orbit having cleared other objects from its orbit, namely Neptune. But it was also my humble knowledge the Neptun and Pluto only have overlapping orbits when it is represented on a 2d piece of paper, but in reality they could never collide. So what's goin on there?

I have an object (lets make it a cube of steel). This cube is perfectly frictionless. somehow I manage to place this perfectly frictionless cube on top of a perfectly level and perfectly frictionless table so that one flat side of the cube is lying on top of this flat table. The table is directly on top of the flat ground. The table is held securely in place (it will never move relative to the ground). The cube is held in place with a clamp that is attached to the ground so that both of them are stationary (relative to the ground). After the clamp is perfectly withdrawn from the cube (it does not give it any momentum/energy) Will the cube move because of the centripetal force of the earth?
If yes, with what velocity? (magnitude and direction)

I thought maybe I could network into a company by taking a non engineering job if necessary and show them my work as the opportunity arises.

***Please number which you are answering!***

1. How many stars does it have?
2. Are there any other constellations that border it (names)?
3. What are the coordinates (in degrees and hours)?
4. What are the brightest star(s) name and magnitude?
5. Any special features worth noting (galaxies, nebulae, meteor showers, etc.)?
6. Where can I find a good picture of all of its stars (Wikipedia's is hard to read..)?

Thanks a bunch!!
