Started programming on a ZX spectrum in the 80's and have moved through Assembly, Turbo Pascal, C++, C#, Fortran. My main area of focus is engineering and scientific computing like numerical methods and 3D graphics.

What happens to a fly floating in the air when the train starts moving @Yan - if the air is moving with the train, the fly will get dragged with it due to air resistance. |

Is there any physics that cannot be expressed in terms of Lagrange equations? @Spencer - Are you? Because a numerical simulation is done does not mean the models are validated. A model is nothing without experimental validation of the results. In fact, there should be published set of validation examples one can run through, just as they do with FEA software. |

Is there any physics that cannot be expressed in terms of Lagrange equations? @Spencer Nelson - How is the new method validated? When it comes to friction modeling is very hard to ensure the results are realistic and accurate. Also, in my original statement I said it is difficult to model friction with LM, not impossible. |

Is there any physics that cannot be expressed in terms of Lagrange equations? Looking at en.wikipedia.org/wiki/Lagrangian_mechanics how you would describe coulomb friction in a lagrangian? |

Why do white dwarfs shine white? So a white dwarf will not necessarily be "white", but follow a typical hot body radiation distribution and subsequent redding as it cools. And it cools due to radiative heat transfer only? So temperature should drop kind of exponentially. |

Eyes open under water Some animals can see both in water as well as in the air, with no fuzzyness. I wonder how??? |

Why is a 1mW laser dangerous? There is a typo above: $10^{-3}/10^{-6} = 10^3$ not $10^{-3}$. |

What is the difference between “kinematics” and “dynamics”? -1 : I disagree. Kinematic has to do with motions and paths but not with forces and masses. A kinematic description might tell you what are all the possible configurations, but a dynamic description will narrow it down to what is likely to happen in a time sequence. |

How to correctly show units with a vector So how would you show (1 mile, 1 mm, 1 angstrom) in the same vector? I wonder... Maybe (1,0,0)*mile. |
