Meditation methods and the scientific method are teaming up to explore some of the deepest questions about our existence and human nature.

"The human voice: mysterious, spontaneous, primal." With these words, soprano Claron McFadden invites us to explore the mysteries of breathing and singing, as she performs the intriguing modern song "Aria," by John Cage.

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...

In this video Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through changes in free energy and the equilibrium constant. When the delta G is negative the reaction shifts to the right or favors...

Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...

In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to...

In this video Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction...

SciShow takes you to Centralia, Pennsylvania, site of one of the oldest, biggest coal fires in the United States, and explains the chemistry of spontaneous combustion.

Pupil outcome: I can explain what makes a productive discussion and understand what makes an effective active listener Key learning points: - A productive discussion means thinking, listening and speaking clearly to develop it in a...

Pupil outcome: I can develop a discussion by responding appropriately and asking effective questions. Key learning points: - Discussion can be more spontaneous than other forms of spoken language. - Using the ABC strategy can help you to...

Pupil outcome: I can explain different types of Jewish resistance and the obstacles resistance faced during the Holocaust. Key learning points: - Violent and nonviolent methods were used by Jews to resist the Holocaust. - Jews from a...

The 1943 Luria–Delbrück experiment, known as the "Fluctuation Test," demonstrated that mutations in bacteria occur randomly rather than as a directed response to environmental stress, such as viral infection. By showing wide variation in...
