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...
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?
How did J.J. Thomson discover the atom? What experiments did Ernest Rutherford do? Who discovered the electron? What was the contribution of Robert Hooke to the microscope? How did Ernest Rutherford discover the proton? How did Ernest Rutherford discover the atom?
Hall Effect sensors are named after the scientist Edwin Hall, who discovered an electrical quirk of nature back in 1879. It was already known that if electricity is passed through a wide and flat conductor, such as a short but wide piece of metal, the current spreads out equally across its...
Common northern lights questions answered by an aurora scientist We asked Dr. Elizabeth MacDonald a few frequently asked questions about auroras. Dr. Elizabeth MacDonald Space Physicist Dr. Elizabeth MacDonald is a space physicist at NASA Goddard Space Flight Center and one of the founders of the...
The observation of this exponential growth led scientist to ask a powerful question: could we simulate quantum systems using a machine that exploits exactly the same laws of physics? And could we use those that machine to investigate other tasks that are crucial for us? These questions led to ...
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 ...
The Laws of Planetary Motion The creation scientist Johannes Kepler discovered that the planets in our solar system obey three laws of nature. He found that planets orbit in ellipses (not perfect circles as had been previously thought) with the sun at one focus of the ellipse; thus a given ...
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...
