There were only a Ruhmkorff coil and Crookes (vacuum) tube and the man himself.
A good speech by Crookes as to how a microscopic man would look upon the world.
"I have avoided doing so, for I respect Crookes as a chemist," he added.
Crookes at first thought they corresponded to a "new or fourth state of matter."
We have our own observation, joined to the report of Crookes and Richet.
Physicists did not take long to discover that the radiation from radium was very like the radiation in a "Crookes tube."
Professor Crookes got in touch with this new medium in December, 1873.
Mr. Crookes has recommended a very ingenious, simple, and useful filter.
As to the explanation of the phenomena, Crookes thinks that we cannot discover it.
British chemist and physicist who discovered thallium in 1861 and invented the radiometer (1873-76). He also developed the Crookes tube, a modified vacuum tube that was later used by W.C. Roentgen and J.J. Thomson in experiments that led to the discovery of x-rays and the electron, respectively.
