You believe in an invisible god, and dismiss people who say they are trans? Really? |

Of course, if you then die, that’s bad news. You believe in an invisible god, and dismiss people who say they are trans? Really? |

Phalanx is designed to fire a lot of lead shot into the air. The hope is that some of it will hit and destroy the incoming missile even if most of it misses. It is actually a fairly common design of weapons. |

odiousgambit Member since: Oct 28, 2012 Threads: 154 Posts: 5107 | Just heard that we all should have learned one lesson from the Chelyabinsk Meteor event in Russia: If you look out the window and see a big bright flash in the sky, what should you not do? You should not go to the window and gawk, and you should instead get away from that window. Forgetting about the possibility of the later arriving not just sound but terrific shock wave, people instead did just the opposite.

odiousgambit Member since: Oct 28, 2012 Threads: 154 Posts: 5107 | The AI was able to determine that a dead cat is a dead cat. Actually , Schrodinger's equation has nothing to do with cats but "is a linear partial differential equation that governs the wave function of a quantum-mechanical system" acc to wikipedia article. The math might as well be hieroglyphics for me ... as far as the rest of it, stare at this graph for about 24 hours and see if a light comes on I'm Still Standing, Yeah, Yeah, Yeah [it's an old guy chant for me] |

The really tough problem is Navier Stokes which express conservation of momentum and conservation of mass for Newtonian fluids. AI is making headway here as well. Navier Stokes + mass conservation: an equation of state to relate p and ρ, e.g. for an incompressible flow: The 7 Major Unsolved Mathematical Problems

odiousgambit Member since: Oct 28, 2012 Threads: 154 Posts: 5107 | Just saw that Oumuamua* has been quite a bit more perplexing than was originally indicated, with some controversy about it. Apparently the object picked up more speed than it should have just from the slingshot effect. Offgassing like a comet does would explain this, but no comet-tail-like trail was detected at all. This has caused all sorts of speculation and one scientist, Avi Loeb, released a book, "Extraterrestrial: The First Sign of Intelligent Life Beyond Earth" citing the seriousness of the lack of this trail evidence. The universe and the solar system have done a consistently good job of pointing out how little we do know. but see: https://photojournal.jpl.nasa.gov/archive/PIA22357_JPL-20180620-ASTRDSf-0007-Interstellar%20Asteroid%20animation-720p.mp4 * a mnemonic for remembering how to spell and say that is to make it “oh MOO ah MOO ah” which gives pronunciation directly. For spelling it is a matter of remembering the repeated use of 'u' and no use of 'h' [works for me anyway] I'm Still Standing, Yeah, Yeah, Yeah [it's an old guy chant for me] |
