![]() He discovered the electrons are encircling by a volume of positive charge and negatively charged. We have to remember that the scientist J.J Thomson proposed the cathode ray tube experiment on \. According to this experiment, he concluded that the atom does not contain any space and it has a positively charged nucleus. By using this model, scientist Ernest Rutherford performed the gold foil experiment. The plum pudding model of the atom is put forward on \. Thomson an experimental genius?’ ( 1986) Google Scholar, submitted to Social Studies in Science.Hint: We need to know that the cathode ray tube experiment of an atom is conducted by J.J Thomson and he shows the electrons are encircling by a volume of positive charge and negatively charged. CrossRef Google Scholar In my thesis and a forthcoming paper, I discuss other ways in which the mechanical philosophy influenced Thomson's approach to experiment: Falconer, I., ‘J. As Wheaton has pointed out, the mechanical philosophy was implicit in Thomson and Schuster's cathode ray experiments: they assumed that macroscopic mechanical laws carried over into the microscopic realm: Wheaton, B., The Tiger and the Shark, Cambridge, 1983, p. He does not consider any experimental stimulus for the theory changes he describes, nor the influence of these theoretical commitments on Thomson's experimental work. However, Topper deals exclusively with Thomson's theoretical work.

Neither quotes figures for the pressures they were working at, but Schuster appears to have expended more time in evacuating his apparatus. 34 This difference between Schuster and Thomson was probably largely due to the conditions under which they performed their experiments.
