By the 1860s all the pieces of the electricity and magnetism puzzle were in place, except one. The last piece, discovered by James Clerk Maxwell and called (unfortunately) the displacement current was just what was needed to produce electromagnetic waves called (among other things) light.

This is the 6th lesson in the series, "Electromagnetism." It shows how the theory of electromagnetic conduction is used in transformers and demonstrates how a transformer works by applying Faraday's Law. The lesson also demonstrates that there is a relationship between the potential difference in the coils of a transformer and the number of turns. (20:04)

Telescopes are engineered to detect a specific range of wavelengths of electromagnetic radiation. Images from a variety of these telescopes show different aspects of the same astronomical objects. To trained eyes, each of the images in this collection produced for Teachers' Domain contributes details that provide a more comprehensive understanding of the observed object than is possible from a single image. Radio images highlight the presence of cooler gas clouds (especially hydrogen), infrared images show areas of low-energy heat, visible light images depict primarily gases and dust, and x-ray images reveal high-energy heat emissions.

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.

Maxwell's theory says that electromagnetic waves of all wavelengths, from radio waves to gamma-rays and including visible light, are all basically the same phenomenon. Many of the properties of light are really just properties of waves, including reflection, refraction and diffraction. Ordinary light can be used to see things on a human scale, X-rays to "see" things on an atomic scale.

Want to learn more about the topic in this video? Here are some key words/phrases to get your googling started: - Radiation balance - incoming radiant energy from the sun minus outgoing energy heading into space. - Infrared radiation - electromagnetic radiation that is invisible to us; comes in longer wavelengths than visible light and provides energy transfer we call heat. (03:08) Thanks to Kurz Gesagt for illustrating this video! And for composing the music!

Music employs a number of mechanisms for conveying emotion. Some of them are shared with other modes of expression (speech, gesture) while others are specific to music. The most unique way that music communicates emotion is through the use of contrastive scale types. While Westerners are familiar with the major/minor distinction, the use of contrastive scale types in world music is universal. (54:48)
Looking
at the expression of emotion in both Western and non-Western musics,
Brown invokes the theory of Clore and Ortony, who posit three categories
of emotions 1) "outcome" emotions related to the outcomes of
goal-directed actions (e.g., happiness, sadness); 2) "aesthetic"
emotions related to the appraisal of the quality of objects (e.g., like,
dislike); and 3) "moral" emotions related to an assessment of the
agency of individuals actions (e.g., praise, scorn). While
representational art-forms like theater or dance can represent all three
categories, music is probably most adept at expressing "outcome"
emotions, such those that sit along the happy/sad spectrum.

This video role plays how to respond adequately in a conversation. The speakers are both speech pathologists. They also use a fourth grade student to role play both adequate and inadequate ways to respond to a speaker in conversation. This video would be be beneficial for speech language students and also for special education students in the autism spectrum who struggle with social/conversational skills (2:27).

Presented by Dr. David Hill. There are many different types of autism, known as the autism spectrum. The main thing they have in common is that they have trouble communicating with other people. There are three levels of autism, Asperger's syndrome, difficulty communicating with others, interpreting their intentions or emotions, they tend to go on with subjects that interest them, may have a hard time getting jokes, but can live on their own and hold down jobs. The middle, have severe difficulty forming relationships and communicating with others, and understanding what others are saying to them. The most severe are the pervasive developmental disorder. They have a profound difficulty in relating and communicating. Video is of good quality. Video gives good information on autism. Video is good for parents and teachers who want to learn more about autism.

This video shows students in real life settings participating in the ABA program. Different skills are identified to address with each student. Reinforcements are used and the stronger reinforcement the quicker process is seen. (3:36)
