+         '''Try to imagine the solar system before there was even really a star.There would have been a cloud of material flying all around.If everything was very random, then very little would have enough speed to avoid being sucked into the newly forming star. If some things had a velocity in one direction and other things had a velocity in another direction, then they would likely end up dragging on each other, slow down, and get pulled in. What we think happened is that as the sun was forming, it acquired a spin and that spin ended up transferring to the cloud of material, shaping it into a disc which eventually would collect together to form the planets. Without this spin, the material would have just fallen into the sun and it would have burned a little bit brighter.'''],

+         '''I worked on a window-washing robot that cleaned acres of rooftops over a huge commercial greenhouse. Worked great, except when it didn't, and would either break down completely or just get lost and start climbing the wrong parts of the structure. Then repair techs and manual window washers still have to be employed. I think this ends up being a cost/benefit problem where the reliability of our robots and price of implementation isn't quite at the point where it makes this commercially viable for skyscrapers. For what it's worth, I think the Twin Towers actually used a washer robot on the upper floors to limited success.''']
