Software for geometrical optics Geometrical optics is simpler in terms of descrbing the way a light beam travels. It completely ignores such effects as diffraction or interference. Ray or wave optics handles just that ... |

Why is GNUplot so pervasive in Physics when there are much more modern tools? And it can be scripted nicely. The output can be TeX as well so you can incorporate is easily in papers... |

Could a bubble of photons make a spaceship massless? Funny for you to say that "Photons (...) [a]re just pieces of light". As Einstein said in a letter to Besso: "50 years of consciously pondering have not gotten me closer to the answer of the question 'What are quanta of light'. Today every rascal thinks he knows but he is wrong" (that's a simple translation from the originally german letter) |

Physics of a skateboard ollie @Mark: I'm sorry if my comment sounded harsh but still it is correct. Your notion of "then applying a downward force on the left axle" is exactly what I disagree on as stated by the cited part of my explanation. You generate no lift with just pushing down the tail (or the right part off the right axle) The force applied to the left axle will generate a rotation which simply counters the initial one. |

Physics of a skateboard ollie @Georg: The sketches are the same orientation as the video. The move is described not from the riders frame of reference but the viewer's. "parallel to the boards surface" means the surface on which you stand on when the board is in a resting position. |
