| ARTICLES RELATED TO insulating | | | | |  insulating: Encyclopedia II - Benjamin Thompson - Early life in AmericaThompson was born in rural Woburn, Massachusetts, in America; his birthplace is preserved to this day as a museum. He was educated mainly at the village school, although he sometimes walked to Cambridge with the older Loammi Baldwin to attend lectures by Professor John Winthrop at Harvard College. At the age of 13 was apprenticed to John Appleton, a merchant of nearby Salem. Thompson excelled at his trade and, coming in contact with refined and well educated people for the first time, adopted many of their characteristics, including an inter ...

| | | | | insulating: Encyclopedia II - Tesla coil - Description Later coils consist of a primary tank circuit, which is a series LC circuit composed of a high voltage capacitor, spark gap, and primary coil; and the secondary LC circuit, a series resonant circuit consisting of the secondary coil and the toroid. In Tesla's original plans, the secondary LC circuit is composed of a loaded secondary coil which is then placed in series with a large helical coil. The helical coil is then connected to the toroid. The toroid actually forms one terminal of a capacitor, the other terminal being the Earth (or "groun ...

| | | | | insulating: Encyclopedia II - Spitz - Companions and toys The charming look of the spitz-type, with its thick fur, fluffy ruff, curled tail and small muzzle and ears, have caused several people to create non-working types designed to be companions or lap dogs. This trend is most evident in the tiny Pomeranian, which was originally a much larger dog closer to the size of a Keeshond before being bred down to make an acceptable court animal.
Other spitz types which have been bred away from working uses are the American Eskimo Dog, the Alaskan Klee Kai, the ...

| | | | | insulating: Encyclopedia II - Speed of light - History Until relatively recent times, the speed of light was largely a matter of conjecture. Empedocles maintained that light was something in motion, and therefore there had to be some time elapsed in travelling. Aristotle said that, on the contrary, "light is due to the presence of something, but it is not a movement". Furthermore, if light had a finite speed, it would have to be very great; Aristotle asserted "the strain upon our power ...

| | | | | insulating: Encyclopedia II - Speed of light - Communications The speed of light is of relevance to communications. For example, given that the equatorial circumference of the Earth is 40,075 km and c, the theoretical shortest amount of time for a piece of information to travel half the globe is 0.067 second.
The actual transit time is longer, in part because the speed of light is slower by about 30% in an optical fibre and straight lines rarely occur in global communications situations, but also because delays are created when the signal passes thro ...

| | | | | insulating: Encyclopedia II - Brain - Mind and brain A distinction is sometimes made in the philosophy of mind between the mind and brain. The brain is defined as the physical, biological matter contained within the head, responsible for all electrochemical neuronal processes. The mind, however, exists as something outside of the brain. The mind is sometimes thought of as consciousness, the soul, or some other non-physical center of thought.
The inability to determine what consciousness is has led to the mind-body problem.
Some philosophers such as strong AI theorists believe that the mind is analogous to comp ...

For example, in the Southern United States canned pork brain in gravy can be purchased for consumption as food. The form of brain is often fried with scrambled eggs to produce the famous "Eggs n' Brains".[18]
The brain of animals also features in French cuisine such as in the dish [tête de veau], or head of calf. Although it might consist only of the outer meat of the sk ...

| | | | | insulating: Encyclopedia II - Coaxial cable - Interference and troubleshooting Despite being shielded, interference can occur on coaxial cable lines. Eventually, the insulation degrades and the cable must be replaced, especially if it has been exposed to the elements on a continuous basis. The copper screen is normally grounded, and if even a single thread touches the inner copper core, the signal will be shorted out. This most often occurs at improperly installed end connectors and splices. Also, the connector or splice must be properly attached to the copper screen, as this provides the return electrical path for the signal. Low frequency singals (below 100 ...

| | | | | insulating: Encyclopedia II - Speed of light - Overview According to standard modern physical theory, all electromagnetic radiation, including visible light, propagates (or moves) at a constant speed in a vacuum, commonly known as the speed of light, which is a physical constant denoted as c. This speed c is also the speed of the propagation of gravity in the theory of general relativity.
One consequence of the laws of electromagnetism (such as Maxwell's equations) is that the speed c of electromagnetic radiation does not depend on the velocity of the object emitting t ...

| | | | | insulating: Encyclopedia II - Spitz - Adaptation to the Arctic Spitz types are well suited to living in harsh northern climates. They often have an insulating, waterproof undercoat that is denser than the topcoat to trap warmth.
Small ears help reduce the risk of frostbite and thick fur grows on the paws to protect the dogs from sharp ice.
However, many spitz-type breeds retain wolflike characteristics such as excessive independance, suspiciousness, and aggression towards unfamiliar humans or other animals, and can therefore require much training before they become manageable. Some, such as the Karelian Bear Dog, ...

| | | | | insulating: Encyclopedia II - Tesla coil - Instances and devices Tesla's Colorado Springs laboratory possessed one of the largest Tesla coils ever built, known as the "Magnifying Transmitter". The Magnifying Transmitter is somewhat different from classic 2-coil Tesla coils. A Magnifier uses a 2-coil "driver" to excite the base of a third coil ("Resonator") that is located some distance from the driver. The operating principles of both systems are similar. The world's largest currently existing 2-coil Tesla coil was made by Greg Leyh. It is a 130,000 watt unit, part of a 38 foot tall sculpture. It is owned by Alan Gibb and currently resides in a private sculpture p ...

| | | | | insulating: Encyclopedia II - Tesla coil - Popularity Tesla coils are very popular devices among certain electrical engineers and electronics enthusiasts. Someone who builds Tesla coils as a hobby is called a "Tesla coiler", or simply "coiler". There are even "coiling" conventions where people attend with their home made Tesla coils and other electrical devices of interest.
It should be noted that there are rather significant safety issues regarding coil assembly and operation by hobbyists ...

| | | | | insulating: Encyclopedia II - Spitz - Migrations About three thousand years ago, dogs began to migrate from the Arctic into temperate Europe, North America, Asia, and to a lesser extent, Africa.
Skeletal remains around 2,000 years old unearthed in Switzerland indicate that spitz-type dogs have inhabited Central Europe for millennia. These dogs are almost certainly the ancestors of the European spitz-types, such as the Keeshond and Schipperke.
Many spitz-types also migrated into Korea and China. Over the centuries, many of these dogs were transported by humans to Japan, most likely from Korea. These Asian spitz types are the ancestors of today's breeds such ...

| | | | | insulating: Encyclopedia II - Spitz - Working Dogs Through selective breeding, spitz types have evolved to fit three purposes helping humans: hunting, herding, and pulling sleds.
The larger and more powerful breeds such as the Karelian Bear Dog and the Norwegian Elkhound were used for big game hunting, helping humans kill moose and elk.
Smaller breeds such as the Finnish Spitz and the Lundehund were used in Scandinavia to hunt birds and smaller mammals.
The largest of all the spitz types, notably the Canadian Eskimo Dog and the Greenland Dog, were used to pull sleds up u ...

| | | | | insulating: Encyclopedia II - Tesla coil - The skin effect myth The dangers of high frequency electrical current are sometimes perceived as being less than at lower frequencies. This is often, but mistakenly, interpreted as being due to skin effect, a phenomenon that tends to inhibit alternating current from flowing inside conducting media. Although skin effect is applicable to good electrical conductors (i.e., metals), the skin depth of human flesh at typical Tesla Coil frequencies is still of the order of 60 inches or more. This means that high frequency currents will still preferentially flow through ...

| | | | | insulating: Encyclopedia II - Switch - Biased switches A biased switch is one containing a spring that returns the actuator to a certain position. The "on-off" notation can be modified by placing parentheses around all positions other than the resting position. For example, an (on)-off-(on) switch can be switched on by moving the actuator in either direction away from the centre, but returns to the central off position when the actuator is released.
The momentary push-button switch is a type of biased switch. The most common type is a push-to-make switch, which makes contact when t ...
