Chinese Lunar Calendar

January 12th, 2010 Owen Jones No comments

Prior to their adoption of the Western solar calendar scheme, the Chinese almost wholly 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 method still serves as the basis for determining many seasonal holidays. This coexistence of two calendar schemes has long been accepted by the people of China.

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

A lunar month is determined by measuring the period of time needed for the moon to finish 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 made up 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 combination 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 needs to make a number of astronomical calculations.

First of all, you have to determine the dates for 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 Gregorian calendar. Anyone who sought to work with them had to follow suit. This is why national policy often differs from local custom in Third World countries.

The government desires to trade on the International markets, but the ordinary family in the country can not. So, the government adopted the Gregorian 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 example but no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for instance in Muslim countries.

Presents and Gifts - 5 Top Tips

January 10th, 2010 Owen Jones No comments

It is a global custom to give gifts for such occasions as birthdays and wedding days, but after that is where the countries start to differ. Britons and people tracing their history back there give gifts on Christmas Day as well.

However, many other Europeans give presents at Christmas on Saint Nicholas’ Day or December 6th. Non-Christian countries usually give gifts at New Year.

No matter what you do in your country, giving a present requires thought. The stores are usually full of junk at these present-giving times of the year, but there is also a lot of good stuff about, at a price. The alternatives are twofold basically.

You can either make something which will be unique, I suppose that this includes personalizing a shop-bought gift or you can think outside of the box, which many people find quite hard. Personally, I find it hard, but it does get easier the more often you try it and the better you know the person you are going to give the gift to.

Here then are a few ideas which you may resolve to take on board ‘as is’, or they may inspire you on to better ideas. As I write, Christmas is coming up and then it is Saint Valentine’s day before you know it. We definitely get plenty of occasions to practice buying presents in the West!

A Plot Of Your Own: I come from Wales in the UK (is there any other?) and up the way from me a local strip of green-belt land was in trouble. Experts said that it ought to be planted with trees, but the authorities did not have the money, so they advertised six feet square plots of land for sale with a sapling of your choice on it.

You also got a title deed, directions and a photo. In addition, the tree would be maintained for five years until it was established. I am aware that this is not the only place that did this and it was probably not the first either, but it makes a good gift for a teenager who is wondering what he or she can do to help the environment.

The Key To Success: some children and their parents will be grateful for this one. Search the second-hand shops for an older or even an bizarre money box. Fill the money box up to a certain level with a variety of coins that bring that level up to the value that you want to give, but leave plenty of space for the child to put money in too. Who do you give the key to? That depends on how well you know the child.

Starting A Collection: this is a brave, but good one. If you know the child well or are prepared to take on a commitment (such as a godparent should), you could choose a set of collectables, such as plates, glasses or coins and buy two or three examples to start the collection off. You can add to it every year. Others will be thankful to you too because they will jump on the band wagon.

In The Bag: if your friend is an invalid or just is temporarily in hospital, it is beneficial to give a wicker basket or a nice bag full of handy items. Choose the items to suit your friend, but everyone might like a writing pad, a pen, a comb or brush, wet wipes or tissues, a small book of verse, a miniature radio with ear plugs, a mirror, straws, a bottle opener, only you know, but you get the idea, I’m sure.

Stamp It: you can buy a large packet of literally thousands of foreign stamps for very little. Buy a stamp album and hinges and you could start a lifelong obsession. It also gives you gift ideas for years to come too.

An Introduction To Astronomy

January 3rd, 2010 Owen Jones No comments

Despite the fact that astronomy is the oldest science, it is still at the forefront of not only scientific thought, but also that of the public at large. Who hasn’t gazed up at the galaxy while walking home late at night and wondered? Having said that though, the ancient people of definitely the northern hemisphere, but probably both hemispheres, knew the movements of the stars and planets more profoundly than most of us do nowadays.

They understood even then, thousands of years ago, that most stars appear to appear in the Eastern skies at night and travel on circular paths. They also noticed that some ’stars’ were ‘wanderers’ (we call them planets) and that sometimes they went ‘against the flow’.

They also named groups of stars that we now call constellations or even galaxies and knew that those visible in the winter were not the same as those visible in the summer.and that others were visible all year round. The average common man of 5,000 - 10,000 years ago almost certainly knew more about the movement of the heavenly bodies than the average common man of today does. (I mean men and women here, of course).

They learned how to calculate or at least locate the extremities of the sunrise and went to extraordinary lengths to mark those positions with huge stone structures, such as Stonehenge in the United Kingdom, probably to facilitate the location of certain positions of the sun or other planets or stars, which may have been important to their religious beliefs or crop cycles.

In 1609, Galileo invented the first artificial device for studying the stars and planets. It was the first astronomical telescope and through it he was able to observe things millions of miles away that no person had ever seen before. Because of the conclusions he came to from his observations, he had trouble with the Roman Catholic Church and was often in serious danger for his life, so outrageous were his discoveries.

But humankind was not to be put off, and since then we have gone on to build ever bigger and ever better astronomical telescopes with which we can even detect radio waves, microwaves, X-rays, infrared waves and gamma waves from outer space. Forty years ago, we even travelled to our Moon. and we have sent probes to eight of the nine planets in our Solar System, as well as to quite a few comets and asteroids.

Where are we going next? That decision was always up to the government of the United States and the old Soviet Union, but now there are other players in the field. What will China or India want to explore with their possibly slightly different outlook on life? Or will it be just a question of financial benefit?

The world may be in a state of flux and power may be shifting from its traditional seats in the West, but it has not diminished interest in questions that scientists think can only be answered in space. These are exciting times for the science of astronomy, but then man has always found astronomy exciting.

The Hybrid Car and Petrol Prices

December 25th, 2009 Colin Jones No comments

The appeal and popularity of the hybrid car have grown steadily, especially with the rising worries about high fuel prices together with worsening air pollution. Here are some useful bits of information that could help you learn more about hybrid cars and how they may help you save on fuel and be somewhat shielded from rising gas.

A hybrid car is the sort of car, or any other vehicle, that makes use of at least two different fuel sources to make it run. Both fuel types are used together in some instances to help drive the car more efficiently. There are several different combinations of hybrid car possible, but the most popular hybrid car until now is the gas electric hybrid.

The gas-electric hybrid car, also known as the hybrid electric vehicle or HEV, makes use of a gasoline internal combustion engine or ICE and a separate electric motor to power it. While the ICE makes use of gasoline to make it go, an electric battery is used to store the electrical energy that powers the hybrid car’s electric motor.

The HEV usually has a petrol engine that is smaller in size and weight than the conventional one used in standard gas powered cars. Use of more advanced technology makes this possible and allows the HEV to have better running efficiency as well as substantially reduced polluting emissions.

Apart from the gas engine, the hybrid electric car also has a special electric motor built in that not only provides added power to the car but also acts as a generator when it is not being used. The electric motor acts as a generator, in situations when it is not being used to drive the hybrid car, to help charge the battery for added efficiency.

In a common HEV set up, the car uses its electric motor when being propelled at very low speeds, say, in traffic jams. The gasoline engine acts as a secondary power source when the HEV needs much more power, such as when climbing a hill. The gas engine also compensates the electric motor with power whenever the car calls for it in order to go faster such as when overtaking. The gas and the electric motor can also work together at certain instances when needed.

Since the hybrid electric car makes use of both an electric motor as well as a gas motor, a substantial improvement in car mileage is achieved. A hybrid electric vehicle or HEV can run longer distances using the same amount of petrol compared to a conventional petrol powered vehicle.

When the electric motor is being used, gas consumption is reduced. This results in quite a bit less gas being used when running the same distance as a traditional petrol powered vehicle. And because the hybrid electric car has a smaller, lighter petrol engine, the hybrid car also runs more efficiently because of less engine weight compared to a conventional car’s engine.

The working components of the hybrid car engine are also smaller and require less energy to move. This efficiency makes the hybrid electric car quite a great option for people concerned with rising gas prices. Using a hybrid car can help drivers save a substantial amount of petrolwhen traveling. Not only that, using the hybrid car can also help in reducing polluting emissions by using less petrol while travelling.
