13 нояб. 2019 г. · On April 30, 1897, British physicist J.J. Thomson announced his discovery that atoms were made up of smaller components.

2 мая 2022 г. · JJ Thomson is often hailed as the discoverer of the electron based on that lecture 125 years ago. Of course, history is always more muddled than that.

27 июн. 2022 г. · Thomson likened the composition of atoms to plum pudding, with negatively-charged 'corpuscles' dotted throughout a positively charged field.

Thomson found that cathode rays always had the same e/m ratio, no matter what metals were used for the cathodes and no matter what gas was used in the tubes.
