The Stern-Gerlach Experiment in lauded in textbooks around the world for its contributions to the world of quantum physics. But for a few years, scientists unknowingly praised it for proving the wrong thing! Because instead of proving...

What does an atom look like? Throughout history scientists and philosophers have attempted to answer this question. As a result, they've come up with some useful models for understanding the building blocks of our universe.

In this video Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted...

In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

When Ernest Rutherford realized that atoms have a heavy nucleus, he hypothesized that the way the moon orbits earth is the same as the way an electron orbits the nucleus of atoms. We now know an atom would...

In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom....

Atomic Models: Centuries ago, people didn’t know exactly what was inside an atom, but they had some “ideas”. Around 400 BC, a Greek philosopher named Democritus came up with a theory that everything in the world was made of tiny...

It explains the structure of an atom and talks about Thomson’s model of an atom.

What are the issues with the Bohr model of the atom (Neils Bohr)? Some issues with this mode helped early physicists invent and develop the discipline of quantum mechanics.<br/>

Basics of Electricity and Electronics #1



In this video, we discuss the basic components of electricity like voltage, current, power, charge and energy. Understanding these basic concepts gives one an insight into working of...
