Re: energy flows

[Bernard Cleyet <anngeorg@PACBELL.NET>]

Well, one is not weighing electrons, but it takes a greater, than expected,
electric field to deflect them when going fast, (very hot) (e/m expt. with a
linear accelerator).

what is happening when one picks up a bucket of molten lead and walks?  Hell,
walking with out the bucket.
