Blogging Credit

2011-10-05T00:24:00.000-07:00

I pulled my credit report the other day in anticipation of getting approved for a lease and found out a funny thing. I have NO CREDIT. I don't owe on anything; I have no car loans, credit cards or personal loans-just my mortgage. Not owing a lot of money is a bad thing in the eyes of the credit bureaus. Because I have no revolving debt, I am considered a bad credit risk and I'd only be eligible for bad credit personal loans. You'd think NOT owing money would be a good thing, but I am considered a bad credit borrower because I have no credit currently. There are still plenty of loans out there for folks with bad credit. The problem with bad credit personal loans is the rate is usually much higher and the terms are usually unfavorable to the borrower. I gave up on credit cards a long time ago-the rates just kept going up. I finally gave up on them all together. It's a good thing I have some cash stashed away to expand my business, otherwise I might be forced to take out a personal loans for people with bad credit to get the ball rolling.

When was acupuncture first used?

2011-06-20T04:03:00.000-07:00

Acupuncture originated in China as a form of medical treatment about 2,500 years ago. It has been practised by the Chinese ever since.

The treatment involves the insertion of small metal needles into one or many of 365 spots on human body. Each of these spots, designated by ancient Chinese doctors, represents a particular function or organ of the human body. Accordingly a heart or liver line can be traced by linking the appropriate spots which relate to the particular organ. If a patient has eye trouble the needles will be inserted into his eye line, which may not necessarily come anywhere near the eye. The needles do not go deep, and are not painful. A single treatment may last only 10 minutes.

It is not clear why acupuncture works, but some scientists have suggested that the needles may relieve the nerves affecting a disease.

Since the beginning of this century the treatment has been introduced in the West. At first there was much scepticism, but recently acupuncture has been widely accepted and has been found to be not only a cure but also a valuable form of anaesthetic.

How will people get to the stars?

2011-06-18T03:27:00.000-07:00

If we built a big enough spaceship, whole generations of people could live and die on board. There would always be new children to grow up and take over the ship. Another idea is to freeze people. They would be unconscious but alive during the flight to the stars. When the ship got to a star, they would thaw out and work the spaceship. But by the time they got back to Earth it would be very different. Thousands and thousands of years would have passed.

Until spaceships go faster we will have to use robot probes to reach the stars. They will be the first step towards exploring the Universe.

What is sound?

2011-06-18T03:25:00.001-07:00

According to biologists and doctors, sound is what is perceived by the ear. Physicists are more precise; they explain that our perception of sound is the result of certain vibrations travelling through the air and reaching our eardrums. These vibrations obviously have to start somewhere, and that somewhere is what the physicists call the ‘sound source’. A book falling from a table is a source of sound, so is a glass breaking on the floor. Certainly at the moment they fall, we hear a sound. Even water can be a source of sound - one thinks of rain falling against a window-pane or into a puddle. When a sound source is too far away the vibrations do not reach our ears and we hear nothing. In fact the waves produced by sounds or noises can only be transmitted through the air, water or some other specific materials. We can all remember Indians in cowboy films placing their ear to the ground in order to hear the enemy’s horses approaching, and how they were able to judge which direction they were coming from with amazing accuracy. The vibration produced by the horses’ hooves was transmitted through the earth.

Sound cannot travel though a vacuum, and a simple experiment often carried out in school science lessons proves this. A vacuum pump is connected to a bell jar in which has been placed an electric buzzer. As the vacuum pump removes the air from the jar the sound gets weaker and weaker. If one could create a complete vacuum inside the jar, which is practically impossible, one would hear nothing at all.

What is resistance?

2011-06-14T04:01:00.000-07:00

When water is pumped through a pipe, it is held back to a greater or lesser degree by the walls of that pipes. The longer the pipe, the greater the loss of power induced by this resistance. It is easy to see that the resistance of a narrow pipe will be greater than that of a broad pipe. The material which the pipe is made of is important also. If it is smooth, it will offer less resistance than if the internal walls are rough or grooved.

In an electrical cable, the free electrons moving along it are held up every time they come into contact with the atoms which the wire is made of. The principle is the same as for the pipe. The longer the cable, the greater is the number of collisions between electrons and atoms, and hence the greater the resistance. Thin wires offer greater resistance than thick wires. Again, the material the wire is made of is important - an iron wire will offer greater resistance than a copper wire of the same thickness and length.

Some materials have a very high resistance, i.e. the current has great difficulty in passing through-them. These materials are called insulators, and they include glass, plastics, porcelain and rubber. Another factor influencing resistance is temperature. When the temperature rises, the atoms move rapidly to and fro within the wire. This movement causes more collisions with the’ free electrons and so restricts their movement. Thus the higher the temperature the greater the resistance. There are some exceptions to this rule which we will not deal with here.

The unit of resistance is the ohm, named after the German physicst Georg Simon Ohm, who lived from ~ 789 to 1854.

How does a fuse or circuit a breaker work?

2011-06-11T04:00:00.000-07:00

When the current in an electrical circuit becomes too strong, there is a danger that it will cause a fire. A fuse or circuit-breaker is therefore put in as a safety measure. A fuse is made of some insulating material such as porcelain and contains a thin wire which has a very high resistance. Any electrical current coming into the house has to pass through such a device, and if the intensity of the current reaches a certain level the wire melts with the heat produced and cuts off the supply, thus preventing the electrical circuits from overheating. Fuses are classified according to the maximum current they can withstand. Thus there are fuses rated at 2 amps, 13 amps, 15 amps and 30 amps. The disadvantage of the fuse is that once it has melted either the wire or the whole fuse, according to the type, must be replaced. For this reason devices known as circuit-breakers are now being introduced, which do away with this problems. They have an automatic-mechanism which cuts off the current when it becomes too high, but can be reconnected simply by pressing a button. Before replacing a fuse, or pressing the button on a circuit-breaker, the cause of the short-circuit must be traced and remedied, otherwise the fuse will blow, or the circuit-breaker drop out again. Aircraft often have complicated electrical systems which must be protected, and on many modern airliners you can see an impressive array of circuit breakers

What are Siamese twins?

2011-06-08T04:00:00.000-07:00

Siamese twins are babies who are born joined, together. They are joined by a bridge of flesh through which the blood flows from one twin to the other. So the twins share the same blood circulation systems.

The name “Siamese” originated from a famous pair of such twins from Siam who were exhibited for many years in the 19th Century.

Nowadays, with the great advances in medicine and surgery, it is often possible to separate the twins, enabling them to live freely and independently from each other

When was the stethoscope invented?

2011-06-05T03:54:00.000-07:00

The stethoscope was invented by a French doctor, Rene Theophile Hyacinthe Laennec, in 1816. His stethoscope was a perforated wooden cylinder one’ foot long, and he go~ the idea for it from the sight of children scratching one end of a wooden beam with a pin and listening to the transmitted sound at the other end.

He put one end of the tube to his patient’s chest and listened to noises made by the heart and lungs. He gathered evidence of what these sounds meant by comparing the various noises heard in living patients with the type of disease seen after they died. In 1819 he published his findings in one of the great books of medicine De I’Auscultation Mediate, and the stethoscope soon came into general use.

Auscultation (listening to sounds within the body) is most commonly used in diagnosing diseases of the heart and lungs. Nowadays a stethoscope is generally binaural (for both ears) and has two flexible rubber tubes attaching the chest piece to spring-connected metal tubes with earpieces. In listening it is often necessary to use both a bell-shaped, oepn-ended chest piece for low-pitched sounds, and a flat chest piece covered with a semirigid disc or diaphragm for high pitched sounds. Many modern stethoscopes have both kinds of chestpiece & readily interchanged by turning a valve.

What is a source of light?

2011-06-03T03:53:00.000-07:00

The sun is the chief natural source of light. When it disappears, darkness falls. After a great deal of painstaking investigation, scientists discovered that the Earth itself does not emit light, nor does the Moon. They also demonstrated that in our solar system the planets,like the Earth and its satellite the Moon, revolve around the sun in a perfectly regular orbit.

Issac Newton performed a number of brilliant and amazingly simple experiments which enabled him to define the composition of solar light. What we call ‘white light’ is in fact made up of a wide range of different colours. By using a piece of glass called a prism, Newton was able to split light up into its different components and in this way discovered the ‘solar spectrum’, which consists of seven colours: red, orange, yellow, green, blue, indigo, (a very dark blue) and violet. In fact we don’t need a prism to see all these colours, we have only to look at a rainbow.

When was aspirin first used?

2011-05-30T03:52:00.000-07:00

Aspirin was first introduced into medicine in 1899 by H. Dreser of Germany. The word aspirin is actually the trade name for a preparation of acetylsalicylic acid.

During the last century many preparations of this acid were introduced for medical purposes, but Dreser was the first person to produce one which was considered satisfactory.

The main ingredients of aspirin occur naturally in the flowers, fruits, leaves and roots of many plants. South American Indians were familiar with the beneficial effects obtained from the bark of sweet birch and the leaves of the wintergreen shrub, which produce a medicine very similar to aspirin.

Aspirin is widely used for the treatment of headaches, sickness, colds and influenza. But too many aspirin tablets, instead of relieving the patient, may cause dizziness, headaches and sickness, and so they should be used carefully

How do musical instruments produce sound?

2011-05-27T03:51:00.000-07:00

A musical instrument produces sound waves which travel through the air and make our eardrums vibrate. The main types of musical instrument are wind instruments, stringed instruments and percussion instruments. The ‘string’ family includes the violin, the cello, the guitar and the mandolin.

Wind instruments are made of brass or wood. They are instruments in which sound waves are produced by blowing into a mouthpiece.

In percussion instruments, the vibration of the air is produced by striking by hand or with sticks, a skin stretched over a wooden or metal cylinder which acts as a resonator

Can some beings perceive ultraviolet light?

2011-05-21T03:50:00.000-07:00

This question is important since ultraviolet rays can in some cases be harmful to human beings. However, we cannot see them with the naked eye, whereas it has been proved that bees, for example, are perfectly able to perceive them. For bees, ultraviolet rays are a kind of light. This can easily be proved by shutting the bees up in a box whose only opening is a small hole. If a red light is placed in front of the hole, nothing happens, but if a source of ultraviolet light is shone at it the bees start to move towards the hole. It would appear that red is not a visible form of light for bees, whereas ultraviolet is, since they are attracted to it. Ultraviolet rays are carried in sunlight and feed the skin with the vitamin D which they contain. Vitamin D prevents a terrible disease called rickets. Infra-red rays cannot be perceived either by the human eye. They are so called because of their wavelength, which is greater than that of light. They are used in medicine for therapeutic .purposes, because they are able to penetrate the tissues of the body; Infra-red, ultraviolet and X-rays all belong to the great family of electro-magnetic radiations. Radio waves also belong in this class; they can travel anywhere, including through a vacuum and interstellar space, at the same speed as light - 300,000 km a second. Ultraviolet rays, which are found in minute quantities in sunlight, are harmful to the eyes, and can also be dangerous for the skin if it is exposed to them for too long. When sun-bathing, it is advisable to take precautions to filter out the ultraviolet rays. Many commercial sunbathing creams have screens that will do this, but not all - so it is wise to check.

When were antiseptics first used?

2011-05-18T03:50:00.000-07:00

Antiseptics were first used in 1865 by a surgeon called Joseph Lister, in London. He was helped by his knowledge of the work of Louis Pasteur, a French doctor, who had discovered that putrefaction (rotting), was caused by live bacteria and not by a chemical process.

Lister, thought that bacteria could be destroyed before they entered a wound and poisoned it. He first tried the treatment on a compound fracture.

Carbolic acid was applied to the wound in the hope that this would provide a barrier against the germs in the atmosphere. The experiment was successful and led to a great advance in surgery. Various kinds of antiseptics came into general use to combat bacteria.

How is oil drilled?

2011-05-15T03:49:00.000-07:00

A drill pipe is sunk deep into the seabed, more pipes being added to lengthen it, and make a long, watertight tube.

At the bottom tip of the tube the drill bit spins around at a tremendous speed, gouging out a circular hole in the rock of the seabed, about the size of a dinner plate. It is called the borehole.

The drill bit is made from hard steel which is shaped into powerful metal teeth. These wear down very quickly, so they are studded with industrial diamonds for extra strength. Diamonds are harder than rock, so they do not wear down during drilling. They are not the diamonds set in jewellery, but have been specially cut, heated and dipped in chemicals.’

The bit gets hot as it drills. It is cooled by a muddy mixture of chemicals pumped inside the watertight tube. This ‘mud’ carries away the loose rock chippings and keeps the hole free of rubble.

As the ‘mud’ flows backup the tube, it passes through a filter. All the’ rock pieces an~ cleaned out, and the pure ‘mud’ travels back up to the top of the pipe, ready to flow down the tube again.

Scientists on the oil rig examine the ‘mud’ carefully, looking for loose chippings containing drops of oil. If the ‘mud’ is frothy with tiny bubbles or trapped air or gas it might be that the drill has struck oil, as gas and oil are often found together.

When the bit pierces the spongy rock that contains oil, the gassy air fizzes up the borehole in a great spurt, bringing the oil with it. After millions of years the gas and oil have found a way to escape.

But the thick ‘mud’, moving up and down the pipe, traps the escaping oil. A great tap, called a valve, is fitted over the drill hole, The oil flow can now be turned on and off like running water.

The many pipes’ and valves, spread all over the oilfield, are nicknamed Christmas trees.

Which was the first disease to be defeated by vaccination?

2011-05-12T03:48:00.000-07:00

During the 18th century 60,000,000 Europeans died of smallpox, yet today the disease is rare, thanks to a principal advanced by Dr. Edward Jenner (1749-1823).

Ancient country’lore said that contraction of cowpox (transmitted from cows to humans through sores on the udders during milking) prevented smallpox. Jenner investigated thoroughly, and on 14 May 1796, innoculated an eight-year-old boy with cowpox, producing a mild illness. Later he injected him with smallbox, which was successfully resisted.

Vacccination the injecting of material which causes formation of antibodies and resultant immunity, has since been used to prevent such diseases as cholera, polio and typhoid.

When were contact lenses invented?

2011-05-09T03:47:00.000-07:00

The first contact lenses were made by AE. Fick in 1887, but were not successful. During the early part of this century opticians tried to produce extremely thin shell-like lenses to fit closely over the eye. An impression was taken of the eye and a glass shell made which, with a suitable fluid under it, covered most of the eye. After 1938, plastic was used instead of glass, and about 1950 smaller lenses were introduced which covered only the cornea and floated on a layer of tears. These lenses, only 7 to 11 millimetres in diameter and 0.1 to 1 mm thick can usually be worn all day without being removed.

‘Besides being invisible, contact lenses provide a much wider field of vision than spectacles. They are more practical for use in active sports, because they are not easily lost or broken, and they can be tinted for use as sunglasses. But contact lenses are not effective in all cases of eye trouble. They are also expensive, and some people find difficulty in learning to wear them.

As research continues, even smaller and more flexible lenses are being developed.

What is magnetism used for?

2011-05-06T03:47:00.000-07:00

The phenomenon of magnetism was first put to use by man when the Chinese invented the magnetic compass. The Earth is surrounded by a magnetic field which has a north and a south pole. These magnetic poles are very close to the true geographical poles, and ‘the needle of a compass will point towards the magnetic pole. The difference between magnetic north or south and ‘true’ north or south is called variation.

A piece of metal can have magnetism induced in it so that it too has a north and a south pole. The north pole of a magnet will attract the south pole of another magnet, so that they stick together. This is called magnetic attraction. If a piece of soft iron is wound round with wire and an electric current is passed through the wire ‘the metal becomes a magnet for as long as the current flows. This is called an electro-magnet, and is very useful as it can be used to operate switches and machinery. Very large electro-magnets can be used to pick up heavy metal objects, swing them round, and put them down

Are atoms really the smallest particles?

2011-05-03T03:46:00.000-07:00

The word ‘atom’ in Greek means ‘indivisible’.

However we know that this term is not all appropriate, and the atom itself is made up of minute particles. It is very difficult to imagine this miniscule world and its components, but it is generally thought of as a miniature solar system, with minute ‘planets’ orbiting round a ‘sun’ which is slightly larger but still invisible to the human eye. This ‘sun’ is the nucleus which forms the centre of the atom. It is made up of one or more protons and several or no neutrons. Protons have a positive charge, whereas neutrons have none. Together they are called nucleons. A number of negatively charged particles, governed by the number of protons, revolve round the nucleus - these are the electrons.

Atoms can be combined in various different ways, and they can also be split, as is now well known.

On close observation, scientists found that particular types of atom emitted rays and particles at very high speed. Later it was found that working with these substances was highly dangerous, but it was vital to continue research on them as they promised to have important applications for mJdical science.

When are contour lines used on maps?

2011-04-30T03:45:00.000-07:00

Contour lines are used when maps are designed to show the physical nature of the land. They do this by linking all points which are the same height above sea level. The width between the contour lines indicates the steepness of gradients or slopes in the area. The closer the lines are together, the steeper is the slope.

On physical maps giving the height of mountains, rivers, lakes and principal towns all areas between certain heights are generally shown in the same colour. This is known as layer colouring.

Other methods for indicating heights include relief maps moulded in plastic to the physical feature raised as on a model. Spot heights may be shown, but these merely give the heights above sea level of certain points of the map and it does not follow that the ground rises evenly from one point to another.

Very old maps have mountains drawn on them. Later ones have lines called hachures radiating from a central point, with longer lines to show gentler slopes. Another system is to show the form of the land by hill shading.” But none of these methods is so effective as the use of contour lines.
