the simplest way of thinking about it, as you say, is as a black box where you don't worry about what's happening inside. All that matters is the net flow around the box. For the box to experience a forward force the air must be experiencing a backward force and have net flow in that direction...

hmm. "wikipedia says.." doesn't sound like a very sound basis for assertions! Although there might not be explicit explanations for how some particles get their inertia and only very provisional ideas about how gravity is linked, I think that the odds are now in favour of something like the...

Sorry this is so long and a diversion from the original question! Ages ago I asked a question here https://www.physicsforums.com/showthread.php?t=307449 and DrChinese answered very helpfully. I wanted to find some actual experimental data for what DrC explained was basically calibrating the...

@Bill_K are you saying that the intertial mass of a proton is only a fraction of its gravitational mass? I understood that, although there was no explanation yet, intertial mass did seemt to correspond with gravitational mass.

Hi The Dehlinger and Mitchell description is good but I would like to find a write up of an experiment testing the much simpler entanglement idea which, as I understand it, can be explained by postulating hidden variables and which the Bell Inequality experiments were designed to 'out wit'...
