Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Multiplying any real or complex number by the imaginary unit j corresponds to a rotation. This is the key feature of j that makes it such a useful number.
Learn how a three-dimensional vector can be used to describe three-dimensional rotation. This is important for understanding three-dimensional curl.

Three unit rotation video of Number 3, a sculpture by David Davies. Number 3 consists of three identical components arranged to create an environment for contemplation and communal interaction. Utilizing the geometry of the tetrahedron, each object contributes to the creation of an implied 'room' defined by entries, exits, seating, and axially framed views. Music: istock - 13829770

This video will provide u more examples of rotation rather than just teaching you the method. At the same time, you will also learn how to find the center point using compass. This video is very important for you to fully understand about rotation. Anyways, If you would like to have more interaction with me, or ask me more question, or suggest some chapter u want to learn, please add the facebook page at "y=mx+c" or www.facebook.com/maths.video.
In this video, we will discover how to rotate any vector through any axis by breaking up a vector into a parallel part and a perpendicular part. Then, we will use vector analysis (cross products and dot products) to derive the Rodrigues rotation formula and finish with a quaternion point of view. Using quaternions allows us to write a very compact formula which will be familiar to those who have used quaternions to do rotations.

In this series of physics lectures, Professor J.J. Binney explains how probabilities are obtained from quantum amplitudes, why they give rise to quantum interference, the concept of a complete set of amplitudes and how this defines a "quantum state". Notes and problem sets here http://www-thphys.physics.ox.ac.uk/people/JamesBinney/lectures.html
In this video I cover the math behind Rodrigues' rotation formula which is a mathematical formula we can use to rotate vectors around any axis. This is a great primer video for quaternions or a good practical application of things like the dot and cross product. Hope you enjoyed!

Detecting Earth rotation using a suspended spinning rotor. The spinning rotor is contained in the glass jar to prevent the rotor from creating disturbing air currents.
How does one rotate points (or vectors) in two dimensions about a fixed point, say the origin? Instead of using angles and circular functions, this video uses linear algebra and basic geometry to rotate points about a fixed point. Ultimately, a rotation is a linear transformation which preserves quadrances, hence algebraically one can use its matrix representation to send points/vectors to other points/vectors; to understand the geometric meaning, one must consider the rational parametrisation of the circle and the relationship between it and the dot product between the vector and its image under the linear transformation.
