The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't feel bad because it turns out that...

What can we learn from the world's most enduringly creative people? They "slow-motion multitask," actively juggling multiple projects and moving between topics as the mood strikes -- without feeling hurried. Author Tim Harford shares how...

In this video Paul Andersen explains how classical waves (like light) can have particle properties. Albert Einsetein used the photoelectric effect to show how photons have particle properties.

In this video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the energy of a...

Hank explains the power of solar energy and describes how it may fit into our diversified energy future.

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because...

In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

There was physics before Einstein in the same way that there was biology before Darwin. Einstein didn’t just add some new ideas to physics. And he didn’t just add a unifying framework for doing physics, like Newton. Einstein took what...

What is the purpose of light? How does light work? Why does Light exist? There had been a controversy about whether light was particles or waves. Albert Einstein showed that light must come in discrete packets of...

Quantum physics simplified. Are Consciousness and Free Will linked to quantum mechanics? The double slit experiment explained. What is the difference between observation and measurement? Since Quantum Mechanics...

The photoelectric effect is a phenomenon that occurs when light, consisting of photons, interacts with the inner structure of an atom. Photons carry a specific amount of energy proportional to their frequency, which is transferred to...

The photoelectric effect is a phenomenon where electrons are emitted from a material, typically a metal, when exposed to light. This effect supports the quantum theory of light and demonstrates the particle-like properties of...

Quantum physics deals with the foundation of our world – the electrons in an atom, the protons inside the nucleus, the quarks that build those protons, and the photons that we perceive as light. These constitute everything that we are...

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...

The History of Physics (Part 2)

Development of Quantum Mechanics: Photoelectric Effect Example 1

So Max Planck kicked things off, but how does the story of modern physics continue? With none other than your favorite scientist and mine, Albert Einstein! He did more than just stick his tongue out and have crazy hair. He elucidated the...

Look, up in the sky, it's a particle! It's a wave! Actually it's both. It's light! How do we know about this stuff? Well, because of Einstein for one. He did more than E = mc^2, you know. But don't stare at the sun to see for yourself,...

This is an introductory video to Albert Einstein's photoelectric effect, the discipline that made him a Nobel laureate. <br/>
