Which ones?Watched this shortly after its release on Youtube and my first thoughts were that I'd like to hear the opinions of certain forum members.
Which ones?
It was a slightly exaggerated way of poynting out (ha) that many of the ways we 'see' some effect or other are analytical constructs that don't correspond to a physical entity. E.g. what we call an electric field is equivalent to the spatial representation of potential gradient. You can measure so many V/m on this vector at this point here, and so many V/m on that vector at that point there, and plot your findings in 3d space and the result is the same as the field.When Lucien writes 'The field is nothing in and of itself'
OnlQQker and readers: One might like to consider whether the experiment in the film, which was only described, but if done in reality is identical to the supply of electrical energy from say a battery with a lamp next to it through a loop of parallel conductors 1 m apart 300km long and shorted at their end, and a battery connected to the same loop with a lamp at its very end 300km away. The conductors assumed to be resistance free.I go and watch something like this...
The usual 'thought experiment' I used to give students was a battery, switch, and an infinitely long pair of wires.OnlQQker and readers: One might like to consider whether the experiment in the film, which was only described, but if done in reality is identical to the supply of electrical energy from say a battery with a lamp next to it through a loop of parallel conductors 1 m apart 300km long and shorted at their end, and a battery connected to the same loop with a lamp at its very end 300km away.

potential fields are derived fields which do not exist in objective reality.
Is this what you meant?
