The Great Wall
Built in stages over many centuries, the Great Wall of China stretches
more than 6,400 kilometers, or nearly 4,000 miles through northern
China. China's first emperor, Qin Shi Huang, began constructing the wall in the 3rd century BC to protect the northern borders of his empire from Mongolians and other nomadic invaders.
Early Japan Feudalism
During the 600s, Japan used China as a model of knowledge for their country. Nobels and officials would be sent to China for "selective borrowing" (Japan selecting the best part of Chinese culture while preserving their own unique identity). Japan created government and writing systems that are similar to the Chinese. During the Heian Period (794-1185), Japan created highy refined culture and arts. Proper etiquette, appearance, and education was very important. This eight minute video is a lectu

Electrical Systems Current (sv)
How does current work? Find out as this teacher from Dallas, Texas, helps you learn. This video is in lecture format - with the teacher speaking into the camera and a dry erase board behind her. She focuses much of her time on the formulas for currents and amps. Some key words include: matter, positive charge, negative charge, repel, attract, electron, coulombs, current, flow, and amp. Run time 04:00.
After Oersted's 1820 discovery that electric currents create magnetism, it was obvious that in some way magnetism should be able to create electric currents. The discovery of electromagnetic induction, in 1831, by Michael Faraday and Joseph Henry was one of the most important of the 19th century, not only scientifically, but also technologically, because it is the means
Electromagnetic induction makes it easy and natural to generate alternating current. Use of transformers makes it practical to distribute ac over long distances. Although Nikola Tesla understood all this, Thomas Edison chose not to, and thereby hangs a tale. Alternating current circuits obey a differential equation identical to the harmonic oscillator resonance equation
How Does a Solenoid Work?
A solenoid works by having electricity flow through its copper
wire that is provided by a power supply and a switch. Learn how a
solenoid becomes a magnet when electricity is supplied to it with
information from a science teacher in this video.
What Is an Electrical Inverter?
An electrical inverter is a device that can create an alternating
