Wave-Particle Duality - Part 1
In this video Paul Andersen explains the wave-particle duality discovered by scientists. In certain situations particles (like electrons and photons) display wave like properties. This phenomenon can best be explored using the double...

Thinking in Energy - Level 3 - Energy and Energy Transfer
In this video Paul Andersen shows conceptual thinking in a mini-lesson on energy and energy transfer. TERMS Energy - the ability to cause change Object - a material thing that can be seen and touched Transfer - the conversion of one form...

Wavelength
In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

Electrochemical Gradient
In this video Paul Andersen explains how the electrochemical gradient is a combination of the chemical and electrical gradient of ions. As ions move across a membrane the potential change creates a hidden force that isn't always apparent.

Floating Candle in Slow Motion
Slow motion video of a classic science demonstration. Why does the candle rise?

Rotational Inertia
In this video Paul Andersen explains how the angular momentum of an object if a product of the rotational inertia and the angular velocity. The rotational inertia depends on the mass, radius and shape of the rotating objects. A sample...

Synthesis and Decomposition Reactions
Atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A combine...

Electric Field of Parallel Plates
In this video Paul Andersen explains how the electric field between oppositely and equally charged plates is uniform as long as you are far from the edge. The strength of the electric field can be determined by either the charge of the...

Stimulated Emission
In this video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and moves to a...

Matter as a Wave
In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

Gravitational Mass
In this video Paul Andersen explains how the gravitational mass is a measure of the force on an object in a gravitational field. The gravitational mass is based on the amount of material in an object and can be measured to a standard kg...

Gravitational Force
In this video Paul Andersen explains how an object with mass placed in a gravitational field experiences a gravitational force. On the Earth this gravitational force is known as weight. The gravitational force is equal to the product of...

The Action Potential
In this video Paul Andersen details the action potential in neurons. The resting potential of a neuron (-70mV) is maintained through differences in concentration and permeability of Na, K, and Cl ions. A graded potential is created as...

Total Energy
In this video Paul Andersen explains how the total energy of a system is the combination of kinetic, potential and internal energy of the objects. He then shows you how to calculate the kinetic energy, gravitational potential energy, and...
