Categories: Alternative conceptions
An example of a historical scientific idea that would now be considered an alternative conception:
"…when the cathode rays strike the anticathode [anode], the negative electrons constituting these rays, which are animated with very great velocities, are suddenly stopped. In consequence of the acceleration they thus undergo, they produce undulations in the ether. This, according to certain physicists, is the origin of the Röntgen rays, which are nothing else than light rays of very short wave length."
Henri Poincaré (1914) Science and Method (trans. Francis Maitland) Dover Publications, 1952.
