"Richard Feynman described the theory as 'mad' "
Maxwell napisal o pomysle ze dookola drutu jest wir magnetyczny tak:
"Professor Challis[20] conceives magnetism to consist in currents of a fluid
whose direction corresponds with that of the lines of magnetic force;"
"Now it seems natural to suppose that all the direct effects of any cause
which is itself of a longitudinal character, must be themselves
longitudinal, and that the direct effects of a rotatory cause must be
themselves rotatory. A motion of translation along an axis cannot produce a
rotation about that axis unless it meets with some special mechanism, like
that of a screw, which connects a motion in a given direction along the axis
with a rotation in a given direction round it; and a motion of rotation,
though it may produce tension along the axis, cannot of itself produce a
current in one direction along the axis rather than the other."
Najlepiej postapil Dirac. Uczyli go EM, bo zostal inzynierem, ale nigdy w
zyciu nie wspomnial ani o Heaviside ani o jego EM.
Ale wir magnetyczny pasuje nauczycielom. Tak ja Sw. Mikolaj przedszkolankom.
