Previous to their implementation of the Western solar calendar scheme, the Chinese almost exclusively followed their own lunar calendar for determining the times of planting and harvesting and festival days. Although people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old system still serves as the basis for working out numerous recurring holidays. This coexistence of two calendar schemes has long been acknowledged by the people of China.

However, this does not only happen in China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.

A lunar month is calculated by measuring the period of time required for the moon to complete its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is corrected every 19 years by the addition of seven lunar months.

The 12 lunar months are further divided into 24 solar divisions characterized by the four seasons and times of heat and cold, all of which bear a close relationship to the annual cycle of agricultural work.

The Chinese calendar – very much like the Hebrew calendar- is a mixture of the solar and lunar calendars in that it attempts to have its years coincide with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.

For example, an average year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When working out what a Chinese year will be like, one must make a number of astronomical calculations.

First of all, you have to determine the dates of the new moons. In these cases, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used by the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.

The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Julian calendar.Anyone who wanted to work with them had to follow suit. This is why national policy often varies from local custom in Third World countries.

The government wants to deal on the International markets, but the normal family in the country can not. So, the government adopted the Julian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for instance and no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for instance in Muslim countries.

For the most part, airsoft guns are the most popular among young boys that eventually will grow into men, which will enjoy the dangerous sport of hunting. The rules of the gun should be consistent with the rules of a real firearm entering the home. Explaining the possible harmful outcomes of misuse can be used as the best safety instruction tool.

These guns are available in most department stores, and vary in size and cost. Those cheaper versions usually average about twenty dollars for just the gun, and sometimes there is a small amount of ammunition included in the package. There are pistols as well as rifle replicas available.

Some guns that are available have a number of different ammunition which can be used by the same gun. One example of the safest ammunition for the younger kids is the soft ammunition. This ammunition comes in many colors and is made of a soft rubber substance. Usually the guns that use this type of ammunition are a good choice for younger age groups.

Handling a gun when it is being carried and not being aimed at anything, is crucial to the safety of the child and surrounding people and obstacles. Always teach a child to carry the rifle replica gun, on the shoulder with the barrel pointed up. Some show children to point the barrel at the ground, this is not the best way to carry a gun. Dangerous possibilities include shooting themselves in the foot, or a possible ricochet from rocks under the grass caused by accidental firing.

Holsters should be purchased, or sometimes a holster comes included with a pistol version of the airsoft guns. Telling a child the importance of storage of a gun, and enforcing these procedures are vital to the preservation and proper firing of the gun, at all times. The rifle versions of the gun can be stored along with real guns in a locked gun safe. This way the child will have to ask the parent to get the gun out, because the key should be kept out of the reach of any child in the home.

Pointed pellets are commonly used to kill a small animal. For children which are not old enough to carry a weapon during hunting season, these types of tips can be used to target pests or fruits, to gain experience with guns, and make the child a better hunter when he or she becomes of age to legally hunt in the residing area.

In summary, airsoft guns can be used as a form of protection by adults that are not allowed to have a real firearm due to whatever reasons. These types of guns need to be treated as real guns, and the best judgments and procedures need to be used at all times. Especially when there are young eyes watching and learning from the adults’ example.

Always remember to operate the gun safely in mixed company, and if false accusations arise, stick to your guns and spread your knowledge to let the trouble makers know you as an adult know how to properly handle a gun. Airsoft guns and other guns can be dangerous and safety rules need to be learned.

The second most essential part of a good home theater set-up is its loudspeakers. You simply cannot attain that authentic theater environment, if you do not have good speakers. It goes without saying too, that the amplifier and player must be equally as good, because any system is only as good as its weakest element.

However, if you do it right, you can easily reproduce the sound quality achieved in a full size movie theater. Unfortunately though, many people seem to get baffled about which speakers they need, when they go to buy for their home theater in order to create real surround sound.

The minimum requirements for a good set of surround sound speakers are a left and right channel speaker, a centre channel speaker and a sub-woofer. The following are the basic speakers that are required to complete a good home theater: front left and right speakers, a centre channel speaker, surround sound speakers. Sometimes people try to do without the centre channel speaker, but this speaker provides a good proportion of the soundtrack in a lot of movies as well as adding depth to the dialogue.

The surround sound makes the film seem more realistic. It is what makes the difference between watching TV at home and going to the movie theater. The option of having this at home has only recently become affordable. The most common systems are: 5.1 channel, 6.1 channel, or 7.1 channel surround sound. The first digit refers to the number of normal loud speakers and the second one to the number of sub-woofers. The amount of speakers that is the best for you, depends on the size and shape of the room you are sitting in. The more is not always the merrier.

The sub-woofer is the cause of the deep bass sound that underlies so many movie soundtracks and these are the sounds that are responsible for heightening the drama in a film. A good sub-woofer is an essential element of your home theater speaker package, if you do not have one, you will miss out on this.

There are many makes on the market and some are cheaper than others, but it is essential that you pick speakers that will work well together. They have to be compatible. If you do not know how to make certain that they are, the best choice for this is to purchase all your speakers together in one kit by one maker. It may be tempting to save money by mixing and trying to match speakers, but if you get it wrong, you will not create the true quality of sound you are hoping to achieve in your home theater.

Some speakers are made to stand on the floor and others are made to hang on the wall. Floor standing speakers are the best for home theater, but they also take up the most room and can have wires running everywhere. If this is not a problem to you, then fine, but if it is, you can solve it by buying wireless speakers.

If you have a nice garden, then you probably have a patio of a deck so that you can get every last scrap of enjoyment out of it. Most patio furniture is left outside for a lot of the year so it is best to get high quality garden deck furniture. High quality garden deck furniture is essential if you expect it to withstand the rigours of all kinds of weather and yet last a reasonable length of time too.

Another factor, particularly these days, is the ecology. People want to have as little impact on the ecology as possible, thereby reducing their carbon footprint, as they say. The manufacture of plastic involves polluting the atmosphere with more CFC’s and disposal can cause problems too. Plastic can take decades and decades to bio-degrade.

Metal patio garden furniture also has its issues. It has to be mined and fabricated and people are beginning to worry about robbing Mother Earth of her minerals, but at least old metal can be recycled. That leaves us with timber and especially hardwood. Before, there was a great deal of concern in almost every country about logging, but a lot of countries have the problem under control now after sustained pressure from the West.

Most people realize these days how important it is to look after our planet. There is even a special day to help people remember the Earth’s dire state called ‘Earth Day’. Using hardwood from replenishable sources is the best way to maintain our forests.

Garden furniture made from hardwood from a guaranteed sustainable source is the most ecological way out. If you maintain your hardwood furniture according to the manufacturer’s recommendations for the type of wood you have, it will last for a decade or more. Far longer than any plastic or metal furniture, which you might well have to replace every two years or so.

Acacia hardwood offers a hard wearing and comfortable alternative to teak. In fact, this type of wood is much like teak, as if you leave it untreated it will transform to a silvery grey color. However, it is best to treat all hardwood once or twice a year with suitable oil in order to maintain the warm tones of the timber.

Most people will have a garden patio furniture set of up-right chairs, loungers and a table or two or a nest of small tables. However, there are a few other pieces of furniture that will help you get more pleasure from your garden. It is nice to be able to sit in the garden after it gets dark or when it is a bit chilly too. This can be achieved easily with a few accessories.

I suggest a patio heater, an electric mosquito killer and suitable lighting. Patio heaters are not dear any longer and a single upright propane heater will keep up to eight people warm, depending on their seating pattern. An electric mosquito killer will usually keep a whole garden clear. In fact, some will keep a quarter of an acre or more clear of flying insects. These two items may provide enough light for you, but is best to have a few spots to highlight a plant in bloom or to read by.

There is no doubt that astronomy is the oldest science and there is also no doubt that astronomy was being studied by everyone, not only the wise men, thousands and thousands of years ago.

We do not understand exactly why they did it, but we can surmise that early man noticed a correlation between the weather and the stars, which were themselves not fully understood, of course.

Early man, probably even as far back as Neanderthal man, noticed the relationship between the weather and herd movements and crop growth, or at least fruit and nuts on local trees, if they did not have planted crops.

This means that people could see a connection between the stars and food availability. This relationship was probably ritualized into some sort of religion like early Wicca. Therefore, the stars became a very important part of the lives of every single person and it is likely that astrology and astronomy were widely intermixed by the average person.

However, there were also people who did not only use the stars as some vast celestial clock and who tried to make sense of the whole shebang. I am going to narrate below, eight of the most important dates or years in the history of astronomy before Christ walked on the Earth. In no way forget that they had nothing but an abacus to do there calculations and no telescopes, which came about two thousand years later.

585 BC: Thales of Miletus (c. 625- c. 547), a Greek, predicted a solar eclipse in Asia Minor purely on the basis of his observations and calculations. It was not a lucky guess!

c. 400 BC: the astronomer Oenopedes (5th. century). also a Greek, announces that the Earth is tilted on its axis with respect to the Sun.

352 BC: the Chinese report what they called a ‘guest star’, a supernova, which was the earliest reported sighting.

340 BC: The astronomer, Kidinnu (b. Babylon c. 379 BC) discovers the precession of the Equinoxes, ie the apparent change in the position of the stars caused by the Earth’s wobbling on its axis.

c. 300 BC: a ‘committee’ of Chinese astronomers compile star maps of the visible universe.

c. 240 BC: Chinese astronomers observe and make notes about Halley’s Comet. Also Eratosthenes of Cyrene (c. 276 – c.194 BC), a Greek, correctly calculate the Earth’s dimensions.

165 BC: Chinese astronomers notice sunspots for the first time.

c. 130 BC: the astronomer Hipparchus of Nicea (b. 147 BC), a Greek, correctly calculates the distance to the Earth’s Moon and also rediscovers the precession of the Equinoxes.

You will see from the dates above that clearly not everyone let nature and the stars govern their lives, as the common farmer or hunter did. Some men actually put pen to paper, but before pen and paper even existed, and tried to work out ‘why these manifestations took place?’.

These individuals must have been remarkable men to have worked these measurements out by calculation, observation by the naked eye and rationalization alone.
