J.J. Thomson is the scientist who discovered the electron. At the time of his discovery, he was working in the Cavendish Laboratory at Cambridge University in England. Prior to his discovery, scientists believed the atom was the smallest unit of matter. Thomson proved the existence of ...
What is the particle model theory? What is particle model theory? Is Schrodinger's cat part of quantum physics? Which scientist developed the quantum mechanical model of the atom? What is a Bohr model? Who discovered the quantum theory of how electrons move?
What is antimatter?: Another good simple explanation from Don Lincoln. How J.J. Thomson discovered the electron: This is a great little video that explains how scientists such as Thomson came to the conclusion that electrons must be charged particles inside atoms.Please...
"The northern lights are happening 24 hours a day, seven days a week, 365 days a year," said photographer Chad Blakely, owner of the northern lights tour companyLights Over Lapland. But that doesn't mean they're easy to spot; you need to be at the right place at the right time. To...
Here's a question you've probably never considered: Why are all electrons the same? Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, there's no reason why they'd have to be. In 1940, physicist John Wheeler came up with a...
What the team discovered using high-speed cameras, though, was that when oppositely charged droplets get close enough, tiny flashes ofelectricityjump between them, which Zare calls microlightning. It is much like the way static electricity is generated, or lightning is built up and discharged ...
It was not until the 19th century that the theory of atoms became articulated as a scientific matter, with the first evidence-based experiments being conducted. For example, in the early 1800s, English scientist John Dalton used the concept of the atom to explain why chemical elements reacted...
It has been known that elements are broken down into basic units of a given weight since the early 1800s, in an insight that came from the English scientist John Dalton. He considered these units to be fundamental, indivisible particles, hence his use of the Greek word "atomos". Things go...
Dr. Ken Nomoto at the Kavli IPMU of the University of Tokyo was excited that his theory had been confirmed, adding “I am very pleased that the electron-capture supernova was finally discovered, which my colleagues and I predicted to exist and have a connection to the Crab Nebula 40 years...
Although many studies had suggested that bicarbonate had an obligatory role in electron transfer in photosynthesis, its precise function was not understood. The 1931 Nobel laureate Otto Warburg, who had discovered this phenomenon, made the assertion that CO2 was the source of oxygen in photosynthesis...
