Standing Wave

By

What Is A Standing Wave? A standing wave is the pattern produced in a medium as the result of the repeated interference of two identical waves moving in opposite directions through the medium. All standing wave patterns have nodes and antinodes. The nodes are points of no displacement caused by the destructive interference of the […]

Moon: Terminator Motion

By

Where Is the Moon’s Terminator? How Does the Terminator Appear to Move? As viewed from the Northern Hemisphere, the full moon phase appears to be a white disk-shaped object in the night sky.  From one day to the next, the white disk changes shape as the white, lighted part decreases. The line separating the lighted […]

Milk Protein Groups: Casein and Whey

By

Caseins are proteins in milk containing  amino acids, which are  important for growth and development, especially of young nursing children and animals. The key reasons why cow milk  is such an important human food is that the milk contains casein. Caseins are highly digestible in the intestine and are a high quality source of amino […]

Milk Proteins: Casein and Whey

By

Proteins are chains of amino acid molecules connected by high energy bonds, called peptide bonds. There are twenty two different kinds of amino acids that are combined in different orders to form proteins.  All but nine of the amino acids can be produced by your body. These nine amino acids are called essential amino acids […]

How to turn a frown into a smile. A Frown is an Upside Down Smile. The diagram of the Smiley face represents how I felt when I started revising my website by deleted stuff that was not in use. After permanently deleting 1000 pieces of art that were listed as being unassigned, I was still […]

More Incandescence vs. Luminescece

By

Light is a form of energy. The two common ways for creating light are: incandescence and luminescence. Incandescence is the emission of light due to the high temperature of an object. A burning candle, as well as  light bulbs with filaments produce light because of high temperature. This is not an efficient way to produce […]
