    Having to choose amongst quantum super positions to take a measurement might be one of those essential dualities of existence things, it being paradoxically an exercise of choice in a deterministic universe :/

    The speed of light in a vacuum is a constant.  It changes when it passes through certain, more dense, matter.

    Light (raw photons) only ever travel in a vacuum.  It seems that when a photon (or it's equivalent wave) enters a material it encounters atoms and is either absorbed by them to be re-emitted at some random time in the future which either kills the light or irretrievably scatters it.  Or, the precise electromagnetic (EM) field that is a light photon wave is not absorbed but interacts with the EM fields of all the atoms of the material causing them to jiggle creating an orchestra of additional EM waves that combine and cancel out in all directions except the oiginal direction of the photon and effectively convert the energy of the original photon into a pseudo light-like "particle" but has an effective mass and thus must move slower than the speed of light.   When the orchestrated massy pseudo "particle" of the combined waves of all the jiggling matrix of EM fields reaches the other side of the material the waves collapse again into a photon and it continues its journey at the speed of light.  .

    Keep in mind that to a photon, when travelling through a gas like air there is a lot of empty space between the atoms of the air but as a free raw photon travels this empty space it will eventually come close to some atom in the air and will jiggle its EM fields and go through this pseudo "particle" thing slowing it down just a tiny bit.  That's why even air slows down light just a little.

     

    matter doesnt disappear, it transforms.  the basic idea of a buodome?  or thunderdome.

    Fission seems to be like th first break in a game of pool, fusion is when the cue ball follows an eight ball into a pocket :

    I've found that thinking quantumly tends to win any argument except against a physicist who can solve the equations and then gives up in frustration trying to explain what's really happening. surprise 

    But in thinking about this issue of pseudo light-like "particles" that have effective mass, it seems to me that this could explain (to me, at least) why light has pressure, and why solar sails work.  I could never understand how a massless particle (photon) could impart a force to  objects.  It does and they do.  Perhaps there's a better answer but as you pointed out; when thinking quantumly, sometimes the answer has many doors. indecision

    Aaand in thinking about solar sail some more, I realized that they are reflective and light does not enter the material.  So, either this isn't the explaination at all, or the process of reflection can be thought of in the terms of the pseudo light-like massy "particle" creation process happening at the surface of the material as the energy of the photon is being reflected. One photon in, one photon out but it gains then loses mass as it is reflected, imparting some force to the material in the process? indecision  Is a photon delayed even just a tiny bit as it turns around or is the reflection process happening at the speed of light?  Headache... sad

    Inertia is a drag!

    Mmmmm, jasmine green tea!  Along with my potato, sausage and spicy salsa verde I think I'm waking up finally. Yukon Gold potatoes roast really well in the air fryer, they got nice and soft.  Nom!

    This salsa verde is 'Texas medium', which means it's right on the edge of my heat limit.  The flavor is incredible, the tomatillos come through and give it a nice acid bite.  This will go well in black beans, pinto beans, and on taters and chicken.

    I'm not sure yet what I'll use the peach/pecan bbq sauce on, since getting turkey parts delivered seems problematic.   Maybe I'll go non-traditional and bbq chicken or pork for T-day.  Save a turkey, cook a pig!

    Still overcast and grey outside, yecch.

  • In a dozen minutes I should be at work. 

  • If I do not finish fries soon I will have to throw them out.

    Last night was not fun.  First, up at 1AM to take antacids due to eating too much peppered salami.  Up off and on all night to pee due to massive tea consumption, thankfully no snakes in the toilet. m  Finally sleeping, having a nice weird dream involving a small restsurant on a rocking setup so it rocked back and forth, a very odd sensation.. vertigo in a dream!  Dang dog woke me up at 5:31am barking like mad at SOMETHING I never saw.Got back to sleep and the alarm went off at 8AM.  Gonna be a lot of tea consumed today...

    Ah, radiometers.  I have one on my kitchen window sill.   Interesting devices but they spin the wrong way for the effect to be light pressure. surprise I haven't found an absolute explanation but the closest I've found from a reliable source is that the vacuum is not perfect and there are a few air molecules left.  Usually one side of each vane is colored to reflect more than the other side.  The heating effect of the light seems to cause micro currents around the edges of the vanes and it's these currents of air cycling from one side to the other that causes the force.  I've also heard that by that argument, that placing a radiometer in a cold environment will cause the vanes to rotate the opposite way temporarily until both sides of the vanes achieve thermal equilibrium.  I haven't been able to duplicate that myself.  I can't get into my freezer. frown  And I'm still wondering if the light goes out when the door shuts. surprise

    True radiation pressure on Earth has been demonstrated by laboratory grade vacuum chambers in which a long blade is hung horizontally supported from the center by a long thread of extremely fine material (quartz I believe) and the amount deflection of the blade (a few degrees at best) is measured either directly by scale marks in the tube or by reflecting a Laser beam from the end of the blade and letting the reflected beam amplify the angular movement so that the amount of deflection can be measured more precisely.  Cool science.

    I saw an interesting clip a few days ago about gravity and why things feel a force that pushes them "downward"  It was a discussion about "what is down?".  It seems that the conclusion was things move "down" because they slide through time from fast time toward slow time.  All having to do with curved space and the effects it has on time.  So an object that is moving by the force of gravity is being pushed by time. surprise  I'll see if I can find that clip.

    I saw an interesting clip a few days ago about gravity and why things feel a force that pushes them "downward"  It was a discussion about "what is down?".  It seems that the conclusion was things move "down" because they slide through time from fast time toward slow time.  All having to do with curved space and the effects it has on time.  So an object that is moving by the force of gravity is being pushed by time. surprise  I'll see if I can find that clip.

    Found it: https://www.youtube.com/watch?v=Xc4xYacTu-E  Ignore the joke at at the beginning and force yourself to listen all the way to the end.

    Our down is Australia's up!  No matter how much time is invested...nothing will fall up relative to the ground.  If it does...you should stop smoking that stuff!  laugh

    We can "screw up" and we can "screw down".

    We can "throw up" and we can "throw down".

    We can "get up" and we can "get down".

    We can "take up" and we can "take down".

    We can "show up" and there can be a "showdown".

    So,... Why do we always "wake up"?  Doesn't anybody ever "wake down"?

    inertia is a real thing.

    So is gravity. I get down in the floor to do something, and have a heck of a time getting back up. angry
