So You Think You Can Destroy Evidence With Fire (weather facts)
No commentsBy Rachel Yoshida
Criminals will go to almost any lengths to cover their tracks when they commit a crime that will send them to jail. Starting a fire deliberately will send them to jail also, but sometimes the act they committed will be worse than a fire. People have been using fire to destroy evidence and cover up crimes for hundreds of years or longer and probably at the top of the list is murder.
These days some criminals have learned the hard way that using fire to cover up a crime might not be as easy as it used to be. There have been so many new techniques developed to bring the truth straight out of the ashes. It should make any law breaker afraid of relying on a fire to get away with anything.
In the first place, a criminal will sometimes use some sort of accelerant to start the fire and it is easy for fire investigators to spot this today. They might also use a lighter or matches, but when they use accelerants to start the fire it is a more reliable way to ensure the fire will burn longer and hotter than using other methods. Trained dogs can be used to sniff out accelerants like gasoline, charcoal starter, or other flammable liquids that a criminal might use.
Murderers make the mistake of thinking that a fire can destroy a human body to the point that it can not be identified, but dental records or any trace of DNA can still be use for identification. A murderer might also think that a fire will cover up the cause of a death, but that is not necessarily true either. If there is any usable remains left, many times a coroner will be able to find the cause of death especially if a poison or sever trauma to the body was used.
So actually, when it comes to using fires to cover up crimes today, there is a very good possibility that someone will still be caught and prosecuted for their crime. It is no sure bet that a fire will destroy all evidence that can the guilt of someone or the actual facts of a case. If someone wants to get away with something, they might want to look for an alternative to setting fire to the scene because it is no where near as reliable as it once was.

Technology Used In Astronomy Today
By Ben Needles
Astronomy is a topic in science. For most of astronomy, there are scientific instruments in use. These can be telescopes, which have different technologies, and also that of using computers. In this article, we will take a look at technology used in astronomy today.
Since the dawn of time, man has looked up at the stars in amazement. What were these shimmering lights in the night sky? A torch to light our way? It certainly has been used for farmers, sailors, and many other areas to determine the seasons and other important aspects, however, let us look at the technology used in astronomy.
What was the technology that stone age man and any man or woman today who looks up at the night sky? What is the principle in what is happening when people observe those objects? For certainly the Sun is not as big as my thumb, but actually a size which could eat up Earth and still be hungry!
The point is simple. The stars and other objects in the sky can be millions of light years away. As you look at these objects the light travels to meet your eye. As it meets your eye, it goes through the pupil of your eye. This is the technology of man, and to see more, you will need more light entering.
If your pupil was as large as the Earth, our Moon would appear to be like your hands in front of you. This means that more light we let in, the more we can see, and the bigger it will appear to be.
This is what astronomers and scientists have dedicated themselves to for years. It makes sense. However, the telescopes of today are not using todays technology. Yes, many have some new features, but at the back of it all, they pretty much use 2 different systems.
One of the systems is the famous Galileos refractor. This works with letting light come through a big lens, and finally through other lenses get focused to meet your eye. What happens here is that you get to see objects far away more magnified. In effect you have increased the pupil of your eye!
Another system that is widely used is Isaac Newtons system of telescope. This technology used in astronomy telescopes widely available, is that light enters and bounces off a mirror, and comes back up to find another slanted mirror that sends the light through a lens to meet your eye. Again, increasing your pupil in effect, with technology.
There is much more to the technology used in astronomy today. For example, the Hubble Space Telescope and many other astronomical devices. However, one thing that is becoming more common is to utilize a computer which drives the telescope. This has allowed navigation of the night skies to be much more easier than it used to be.
