Archimedes, a Greek mathematician and scientist, is credited with discovering the buoyant force while taking a bath. He realized that the upward force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
Ernest Rutherford was the scientist who discovered that atoms have positive charges through his gold foil experiment, which led to the development of the nuclear model of the atom.
The scientist who discovered the charge of electrons was J.J. Thomson. He determined the charge-to-mass ratio of electrons through his experiments with cathode rays in the late 19th century.
The scientist credited with inventing the first electronic television system is Vladimir Zworykin.
Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
