Astronomy Fun Facts

February 28th, 2010

For most people astronomy is an interesting science filled with loads of astronomy fun facts. Everything from the size and temperature of our own star, the Sun, to the makeup of distant planets has been established. All of this information can be retold to entertain and enlighten people.

The Sun is a fantastic source of astronomy fun facts. Our own star, which supplies us with all our heat and light is between 91 and 94.5 million miles from Earth. It’s not that nobody has measured the exact distance. It’s because the Earth orbits the Sun in an elliptical, uneven, orbit, so the distance varies depending on where the Earth lies in that orbit.

The Sun is only an average size star, yet it’s size is another terrific source of astronomy fun facts. As normal as it is, it accounts for about 98% of all the matter in our solar system. Even with the huge planet of Jupiter on our side, we’re still only a small 2% of non Sun stuff.

It would take the diameter of about 100 Earths to measure across this average Sun. The solar winds produced by the Sun extends to about 50 times the distance from the Earth to the Sun. In other words, those solar winds go out about 50 AU’s, with an AU being the distance from the Earth to the sun. That’s quite amazing, isn’t it?.

How about astronomy fun facts that don’t have anything to do with the Sun? How about our Moon? It’s the only non-Earth object upon which man has walked so far. And one man actually travelled to the Moon but never left it. Dr. Eugene Shoemaker loved the Moon but was rejected as an astronaut. After his death he was cremated and his ashes were scattered over the moon by the Lunar Prospector spacecraft in 1999.

There are many more astronomy fun facts about the Moon. It’s the site of what may become the oldest footprint known to man. Neil Armstrong’s giant leap for mankind left a print in the Moon dust that will likely still be there in 10 million years time.

Lots of people, in fact about 13% of those asked in 1988, still thought the Moon is made of cheese. And finally, the suits worn by the Moon-walking astronauts weighed 180 pounds on Earth but only 30 pounds on the Moon, because of the Moon’s reduced gravity. Talk about losing weight quickly, eh?

Astronomy fun facts aren’t limited to our close astronomical neighbours. Looking at stars is like looking into the past. Some of the stars we see nowadays in the night sky are so far away that their light takes a million years to get to us. Some of the stars you see may really be images of stars a million years old that aren’t even there any more. There are over 1 x 10 ^22 stars in the universe. That’s a 1 followed by 22 zeros. And all their planets. The number is really quite staggering.

There are thousands of astronomy fun facts that we could relate. But, unfortunately, this article can not be that long. So, please, just get out there at night, look upwards and learn more about astronomy for yourself.

Presents and Gifts – 5 Top Tips

February 27th, 2010

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 gifts 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 one of a kind, I imagine that this includes personalizing a shop-bought gift or you can think outside of the box, which many people find quite difficult. 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 lots of of occasions to practice buying gifts 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 appreciate 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 various 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 pack of literally thousands of foreign stamps for very little. Buy a stamp album and hinges and you could start a lifelong passion. It also gives you gift ideas for years to come too.

Developing A Promotional Strategy

February 27th, 2010

Even if you were to invent something earth-shattering, you would not earn any money from of it if you left the invention on your desk. The only way you can profit from it is by selling it and in order to achieve this, you have to inform people that it exists, that it is for sale and where they may get it from. In other words, you have to advertise it.

The US Patents Office has issued thousands patents for products that never made it and many of those did not make it, not because they were not excellent ideas, but because their inventors did not know what to do with them. A business is more or less the same as a new invention. It has to be marketed, unless it is located in the middle of the only street in town.

Having already started the business, it is to be expected that, you have already worked out your intended market and evaluated the demand for your goods or services. Now you have to convert those potential customers into contented customers and this is where your promotional strategy comes in.

A promotional strategy is nothing more than a for reaching your intended market, which is of course the people most likely to require your services or products. At its simplest, your promotional strategy might consist of just hanging a sign over your door and relying on word of mouth from satisfied customers to circulate, so doing your advertising for you.

In some cases, this is indeed all the advertising a business requires, but the circumstances are not that common really. It works, if you are operating in a very small town or if your product or service is unique or very specialized or if you enjoy a long-standing good reputation. On the other hand, usually, customers need more facts to go on before they will be drawn to your business.

Therefore, the objective of your promotional strategy should be to get in touch with the greatest quantity of potential customers by the most economical use of your means, which may include money, personnel and facilities. This means that you have to divine the channels of communication most used by your potential customers and try to get a message to them through those. This is normally constrained by a budget.

Advertising involves the purchasing of time or space in the media you have chosen in order to market your business to your intended market. You then have to decide which form of advertising you are going to use: institutional or product advertising. Institutional advertising markets the firm’s name as in: ‘Larry’s Boot Shop – The Best In Town’, whereas product advertising is more specific and might read: ‘Nike Walking Boots – 30% off at Larry’s. Offer Finishes Soon!’

Both forms of advertising can be successful and lend themselves better to some media than to others. Institutional advertising is better carried out on shop signs, sign-written vans or windows or promotional calendars, that is, static, long-term, business name advertising and product advertising is better done by newspaper, magazine, radio and TV, where one-off special offers can be promoted.

Biometrics The Greatest Way To Identify Individuals And Create Better Security For Your Company

February 23rd, 2010

Biometrics is, generally, the subject of what can be measured of your biological features. As it pertains to computer security, biometrics has to do with authentication techniques that utilize distinguishing physical features that can be mechanically substantiated.

Biometrics has fast emerged as a new technology for identification and has presently found practical applications in most hi-tech security fields. It is this particular aspect of the technique that we have selected to concentrate on. We seek to explain how easily biometrics can be utilized for security measures and authentication in assorted places.

A rather normal misconception amongst the flocks is that, Biometrics is available only for the rich and individuals with huge pockets. But that is a long way from the reality. Biometrics other than being very efficient, is likewise very cost-efficient.

Utilizing biometrics for discovering and authenticating different people, provides some unequaled rewards. Exclusively, biometric authentication provides an identification on an intrinsic character of a persons body. Soon to be relics, such as smart cards, magnetic stripe cards, normal keys, and so on, can be left at home or duplicated. Keywords can be forgotten or observed.

Finger print electronic scanners are the most widely utilized biometric devices. These devices moved into the mainstream a couple of years ago, when manufacturers began implanting the technology in laptops and regular computer keyboards, as well as offering stand-alone scanners for a wide range of security applications.

Fingerprints stay unaltered throughout an individuals life. In over 140 years of print comparison from all over the world, no two individuals prints have ever been noticed to be the same, not even the fingerprints of identical twins. Really good fingerprint scanners have been put in PDAs like the iPaq Pocket PC, so the reader technology is even easy. They may not function properly in industrial applications since it calls for clean hands to perform properly.

Fingerprint biometrics is just one of the technologies there is also voice biometrics. Comparable to face recognition, voice biometrics creates a way to authenticate an individuals identity without the persons knowledge. It is much simpler to fool (using a tape recording), it is not possible to take advantage of an analyst by simulating another person’s voice.

To sum up, biometrics has become available to every person at all ranges of prices.

The Chinese Lunar Calendar

February 23rd, 2010

Prior 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. Though 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 determining many seasonal holidays. This coexistence of two calendar schemes has long been accepted by the people of China.

However, this does not only apply to 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 needed for the moon to complete its full cycle of 29 and a half days, a standard that makes the lunar year a full 11 days shorter than its solar counterpart. This disparity 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 yearly 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 strives to have its years concur 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 work out the dates for the new moons. In these instances, 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 drop 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 differs from local custom in Third World countries.

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

Astronomy A Guide To The Stars

February 19th, 2010

Did you know that astronomy and space is really all about education. Did you also know that astronomy is also one of the oldest subject’s of study for man kind? To be straight about it, astronomy is one of the oldest sciences that has ever been studied. So the study of our universe is not new but you should remember that astronomy is a science. This is a science for everyone. And, astronomy is a field about which most of the world knows very little.

Astronomy has become a huge night time hobby. It is also something where international boarders blur.. Astronomy is more of an exact science than any other science that people study. While the study of astronomy is an observational science, it still requires the observer to record precise locations and calculations of the stars, particularly of positions of celestial objects. The study of the sky’s is truly bigger than anything else.

The use of physics and astrophysics is extremely important when researching the stars. So is there a difference between astronomy and astrophysics? The study of astrophysics is more the study of how the stars and universe formed to begin with. Astronomy is more a matter of making observations.

The telescope is undoubtedly a very important investigative tool in astronomy. Did you know that Galileo was the first human to use a telescope for astronomy? If you decide to start the study of astronomy, buying a telescope will be the first thing you will need to do.

Now when you are ready to purchase your first telescope, make sure to research the different types and styles of telescope’s to choose the best one for your needs. Buying a telescope is almost the same as buying a car or clothing, no two people are looking for the same thing due to the fact that all people have different tastes. While you will want to get the best telescope you can find you must understand that they can cost anywhere from a hundred to a few thousand dollars so make an affordable choice for your needs.

Telescope parts and accessories can be a very useful addition to your astronomy experience. If you’re just starting out, look for a quality, affordable telescope for beginning astronomy students and casual observers.

You may want to search in your family and friends garage’s and attic’s, many people have a telescope packed away somewhere. You also need to understand that if you acquire a older telescope the lens’s and technology will not be up to date with todays telescopes. You will find that many people will want to use your telescope as long as you have it set up, people are curious by nature and space is the final frontier.

Your friends and family will also be very curious. Astronomy is our tool for unlocking the knowledge of the heavens. As mentioned above, it may be a science, but it also is an outdoor nature hobby. And while it is a science, you don’t need to think about what other people think of you, because everyone thinks that it is really cool. And if you are looking for a way to spend more time with your family, astronomy could be exactly what you are looking for, due to everyone’s curious nature.

Hybrid Cars vs. Plug-in Hybrid Cars

January 27th, 2010

Hybrid cars are on everyone’s minds. Twenty, forty, or fifty dollars for a full tank of petrol? Who in their right mind wants to pay that sort of money? However, frustrated, the gas customer sighs, but pays up. However, hybrid vehicles are applauded for the small amount of gas they need to operate, and they are being driven off the lots of car dealerships each and everyday in increasing numbers.

But what about a plug-in hybrid? Most consumers have heard that these cars are great too. Then, a person might be asking him or herself, what exactly a plug-in hybrid is? How do they work, and what the difference between a plug-in hybrid and a regular hybrid is?

Plug-in hybrids are able to run solely on batteries, but they use fuel also. These sorts of hybrid cars have some of the characteristics of hybrid vehicles. They are also are very similar to electric vehicles.

Plug-in hybrid vehicles need to be charged externally by plugging them into an electrical power source. The combustion engine of plug-in hybrid vehicles is used only as a back up. These cars can run only on batteries if so desired, but it is to be expected that these types of hybrid cars be plugged in every day.

Hybrid cars can go just as many miles as a conventional car. Designed to go the extra mile where gas-mileage is concerned, hybrids can be driven on the highway, in cities, or wherever else a person needs to travel.

On the other hand, plug-in hybrids are designed to be driven commuter-length distances, meaning between twenty and sixty miles between destinations. This way, the plug-in hybrid does not have to use its back up combustion engine, but plug-in hybrids can go further using gas too.

Hybrids help to reduce pollution, but they do still pollute the atmosphere. Compared with plug-in hybrids, hybrid cars still have a long way to go as far as pollution is concerned. Because plug-in hybrid cars can run solely on their battery power, they don’t have to emit waste gases at all.

Plug-in hybrids really do cut total greenhouse gas emissions and plug-in hybrids use virtually no oil at all, imported or not. Studies have revealed that electric hybrids emit at least 67% less greenhouse gases than gasoline cars. Since the electric used to power plug-in hybrids is completely renewable, the difference in greenhouse gas emissions may be even greater than the study indicated.

So there you have it – those are the main differences between plug-in hybrids and regular hybrid cars. It could make a big difference, but you would be surprised at how little it actually matters at the moment, but that’s only because plug-in hybrids are not being marketed to consumers yet! But this article should make you excited about the fantastic plug-in hybrid car, coming soon to a forecourt near you.

And it’s going to be a spectacular debut too – people already like regular hybrid cars, but they haven’t seen anything until they see the new plug-in hybrid cars. However, for now, maybe we should just be satisfied with what we already have, because who knows? Before plug-in hybrid cars come out onto the forecourts, something even better might be introduced onto the market.
