Maybe what we need is cheaper physics apparatus so you don't need a physics professorship or a big lab to advance the state of human knowledge. You aren't going to scale down the LHC to fit under your bed when you aren't using it, but you could surely fit an XRF, ICP-AES, AFM, and maybe an optical bench in there. For a while I worked at a satellite company whose first cleanroom was made only a few years back by covering the concrete walls with polyethylene film, and a class-10 clean bench that you stick your hands into is within the reach of lots of people. Lots of amateurs have built fusors, but mostly they aren't doing the work necessary to measure reliable, reproducible results, in part because Vixra doesn't offer any incentive to do so. Radio amateurs are one shining exception here, even if most of them are just using store-bought equipment these days.
