Khan Academy: Lorentz Transformation for Change in Coordinates

Generally, Lorentz transformations require high level math skills, but conceptual understanding can slip just beyond the grasp of many. Using a story and graph about the time and motion of people and cats, viewers of a short video can...

Finishing our Lorentz transformation derivation for t. [11:21]

Recognize the relationship between Gibbs free energy, reaction quotient Q, and cell voltage. [12:31]

Using symmetry of frames of reference and the absolute velocity of the speed of light (regardless of frame of reference) to begin to solve for the Lorentz factor. [10:54]

How fast does the space station need to travel in order to stay in orbit to maintain its circular motion around Earth? This video will show how to calculate that speed. [6:35]

This article from Khan Academy provides information about sound and how it travels through different media. This information is intended for high school physics students.

A video lecture explaining how adding solute particles to a solution can lower the melting point and raise the boiling point of the solution. The concept is explored with illustrations and a video demonstrations. Also included is an...

Take a closer look to see if there is a relationship between relative angles of the axes in reference frames. [7:21]

Explore the roles of DNA polymerase, primase, ligase, helicase and topoisomerase in DNA replication. An explanation of leading and lagging strands.

Look at how regulatory DNA sequences can repress or promote gene transcription, particularly in bacteria operons. [10:10]
