Cycles Per Second Sound Waves
739 wordsResonance and Sound Physics and Music Since sound is the medium of music, most of the physics of music is the physics of sound. It's important to remember that sound waves are compression waves. You can imitate a compression wave by stretching out a slinky (you do have a slinky, don't you? ) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope. Take a tuning fork (you do have a tuning fork, don't y...

Visual And Auditory Australian Aborigines
1,614 words... misconduct, priests profiting from gifts in return for the drug, or simply the economic decline of the tribes which is said to be due to their peyote usage. In any event, peyotism is strongly look down upon by a majority of Navaho's, yet the members of the Peyote Cult still continue to practice. The fact that the Peyote Cult is only a small division of a larger culture also provides a distinct difference between them and the Aborigines. There is no division among the Aborigines over plant us...

Thermal Expansion Physical Properties
1,122 words... nitride. Cubic boron nitride is the second hardest known substance, after diamond, and has some special applications, such as abrasives in grinding wheels and cutting tools. It does not exist in nature and is thus made synthetically. Titanium nitride is used widely as a coating on cutting tools. IT improves tool life by virtue of it's low frictional characteristics. Silicon nitride has a high resistance to creep at elevated temperatures, low thermal expansion, high thermal conductivity, and ...

Meditation Descartes Sixth Meditation
1,263 wordsThe Mind-Body Problem: Dualism Versus Dual Aspect The Mind-Body Problem: Dualism Versus Dual Aspect Theory Abstract The mind-body problem, which is still debated even today, raises the question about the relationship between the mind and the body. Theorists, such as Ren? Descartes and Thomas Nagel, have written extensively on the problem but they have many dissenting beliefs. Descartes, a dualist, contends that the mind and body are two different substances that can exist separately. Conversely,...

Carbon Atom Molecular Formula
2,405 words3. 2 Lots of carbon compounds seem to be isomers. What is an isomer? In organic chemistry, there are many examples of different compounds which have the same molecular formula as each other, but different arrangements of the atoms in their molecules, (different structural formulae). These compounds are said to be isomers of one another. Isomerism also occurs in inorganic chemistry, but it is less common. There are two types of isomerism common in organic chemistry: structural isomerism and stere...

Physical And Non Physical Shape Mass Mind
460 wordsMind-Body distinction We usually view the mind as the brain and body as something physical. The mind may be better known and understood when one is thinking. When thinking, the mind is made up purely of thoughts and the body is an extension. The mind is telling the body what to do. The mind is a mental entity and the brain itself is the physical body. Although one can not have a mind with out a brain, the mind and brain differ in which one is mental and the other physical. Together the mind and ...

Electromagnetic Radiation Physical Properties
1,125 wordsAnalytical Chemistry Untitled Analytical Chemistry Analytical Chemistry is the branch of chemistry principally concerned with determining the chemical composition of materials, which may be solids, liquids, gases, pure elements, compounds, or complex mixtures. In addition, chemical analysis can characterize materials but determining their molecular structures and measuring such physical properties as pH, color, and solubility. Wet analysis involves the studying of substances that have been subme...
