Equation for the trajectory of a frisbee? I trust that the robot with the most fun wins. Anything else would violate the Spirit of the Game. |

Is a hard drive heavier when it is full? Lay question: what is the ">>" operator? I know two ways to read it ("much greater than" and "right shift bits") but I don't think either of those makes sense. Can you link to a layman-understandable explanation of either the operator or (even better) the equation? |

Does a byte of data weigh anything? I think this would be a good question on physics stackexchange. My uninformed hunch is that the answer is "no" because although the entropy is different, the more-ordered state itself does not have any more energy than the less-ordered state. |

Is it possible to make a hydrogen-alpha solar scope? Great suggestion re. eBay although a quick search doesn't show any that are relevant for solar work. Typically, the etalon is placed at the front of the scope, before all the optics, but now one of the manufacturers is producing a telescope with an internal one -- you might enjoy reading this explanation luntsolarsystems.com/blog/internal-etalon-performance |

How bright are auroras (aurorae)? I live in Hawaii, so it's unlikely that I will have a chance to see for myself this year... You take the bad with the good ;-) |
