    Theory on an extra cause of the expansion of the (uni)verse

    Welcome to these forums. You have more of a question than a theory. But by calling it a theory, you may run afoul of the PF "Terms of Service". I suggest you retitle this post as "Question" rather than "Theory".

    Graduate Quantum interpretations and indistinguishable elementary particles

    Not "wave", "wave function". It provides the weighted distribution of all the places where you might find a particle. When used that way, it directly reflects exactly what is found in particle experiments. So, it is not an "interpretation". Any description of what is going that is consistent...

    Graduate Quantum interpretations and indistinguishable elementary particles

    A photon that is "absorbed and reemitted" will likely leave behind energy and end up with a higher wavelength. Or, in the case of a laser, stimulate the emission of light at a lower wavelength. At a QM entity, exactly what happens when a photon is travelling is not simple. The landing spot of a...

    I'm just a mutt

    OK. Since you're a mutt, I'll make sure she gives you a treat. Welcome to these Forums.

    High School Homemade DC motor not working! Please help

    You appear to have no stator. You need something for those electromagnets to pull towards. Something of iron or steel that is solidly fixed to a position close to where your rotor will be spinning. You will probably want two of these stators, one for each of you two electron magnets. In each...

    Positive wing wash-in dynamic soaring one side

    To be clear, you have made left turns more efficient when thermaling by making the plane asymmetric. When flying the Schweizer, I was equally able to enter a thermal in either direction. I was told by my instructor that should I ever do competitive soaring, I would have an advantage - since...

    Remote Controlled Bowling Ball using Gyroscopes

    You will have a rolling ball, some internal control masses (spinning, static, or some of each), and some ability to apply force to those masses. You can pick a Cartesian coordinate system (x,y,z) to describe the positions within the ball of that internal machinery. I think the biggest problem...

    Undergrad Ice on the moon

    The vapor pressure tells you how eager the ice is to sublimate - to become a vapor. Vapor pressure drops exponentially as the temperature drops. The water vapor pressure of the ice in those permanently shaded regions of the moon is so low, that there are more water molecules that happen across...

    Undergrad Ice on the moon

    From NASA Moon South Pole page: Lighting and Terrain At the lunar South Pole, the Sun hovers below or just above the horizon, creating temperatures upwards of 130°F (54°C) during sunlit periods. Even during these periods of illumination, soaring mountains cast dark shadows and deep craters...

    Physics/math: how much knowledge does a high school teacher need?

    I'm all for pushing statistics over calculus. Calculus is very STEM-oriented. Statistics is much broader. Knowing how to read a study and understand how it applies to your situation. For example, is deaths per mile important? What about deaths per passenger mile? How do studies hedge...

    Point of particular Doonesbury strip?

    Marines have quite a different reputation than Army soldiers. A common slang term for a Marine is "jarhead". If you join the Marines, you can expect rigorous discipline and perhaps very challenging assignments - "First to Fight". They are also the branch that provides the most "ceremony" -...

    How Far is Due East From Due West on Earth?

    For a Proton (with two ups and a down) it is less that 0.90 fm.

    How Far is Due East From Due West on Earth?

    There are two trains, three train stations, and a bird. Those three train stations are all along the same track at 200-mile intervals. From West to East, they are: West Bang Station (WBS), Big Bang Station (BBS), and East Bang Station (EBS). The first train starts at WBS and travels due East...
