When you’re learning about science for the first time, it can be easier to break things down into a simpler form, and you can end up with a few misconceptions about the world. But sometimes this is the first step to understanding that...

One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad...

With scientists’ efforts and their creativity, we finally found “the real philosopher’s stone.” That's right, we can now turn lead into gold... a little bit.

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

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 describes the major parts of an atom and explains how the Bohr Model more accurately represents the location of electrons around the nucleus. Niels Bohr refined the Rutherford model to account for spectra.

How did we get here? Well, in terms of Atomic Chemistry, Hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. From Leucippus to...

Mr. Andersen details the history of modern atomic theory.

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...

We have built beautiful particle accelerators in the search for particles that are even more elementary than electrons, protons, and neutrons. The accelerators smash subatomic particles at enormous speeds, which causes them to shatter...

Rutherford B. Hayes is a rather obscure president, but his election was a pretty famous one. He won on some contested electoral votes, something called the "Corrupt Bargain", and it stained his presidency. People called him...

The Presidency of the United States is the most powerful position in the nation, and is often referred to as the “leader of the free world”. Their power is only equaled by the massive responsibility they hold. They are not always...

The 24th Presidential election in American history took place on November 2, 1880. Back in 1876, while running for President, Rutherford Hayes promised he would not seek a second term. Unlike Frank Underwood, Rutherford actually stayed...
