Java script is a very useful thing to have activated in your browser. For having basic content access and a bit of dynamic, Java script is a key element. Here are some simple steps on how to turn on Java script in several browsers. They are easy and very useful. And they work in all browsers and all types of computers, from PC's to MAC's.

For the Internet Explorer you hopefully use 6.0 or higher. The steps are:

1. Select Tools from the menu.
2. Chose Internet Options.
3. Click Security sheet.
4. Click on the Custom Level.
5. Go down until you reach Scripting.
6. Select enable under Active Scripting.
7. Click OK.

For Netscape Navigator is indicated to use 4.7 or higher. The steps are:
1. Select Edit from the menu.
2. Choose Preferences.
3. Choose Advanced.
4. Choose Scripts and Plugins.
5. Validate the Enable Java Script box.
6. Click OK.

For Mozilla Firefox use may use any version. The steps are:

1. Choose Tools.
2. Choose Options.
3. Choose Content.
4. Validate the Enable Java Script box.
5. Click OK.

For Apple Safari you may also use any version. The steps are:

1. Select Safari from the menu.
2. Choose Preferences.
3. Choose Security.
4. Validate the Enable Java Script box.

This is all you have to do to turn on Java script in any browser. No matter what is the browser you are using. You now have it active and ready to be used. Java script is very useful. All the content on the pages you visit will look much better when you have Java script turned on. The content will be adapted to you as a user. Java script can be used to determine the browser you are using, the width and height of your screen. Also it can create small scripts that create dynamic content. Even smaller games can be designed to use only the Java script.

On the Internet, in applications, all around the blogs, text is everywhere. Most important attributes of a text are it's size and font. The font is the style of the text. The way the characters look like. The font is described in a simple file. The possible extensions for a font file are varied, according to their type. Most common one is the TrueType Font. Which has the extension ".ttf". Other common extensions are the ".ttc" for TrueType Font Collection and the ".otf" for OpenType Font Files. These are the common font type used under Windows. The other operating systems use other types of fonts.

It is very easy to install a new font in Windows XP. First step is to download the font you want. There are lots of fonts available on the Internet. Tens of thousands of fonts await on The Internet. All with the single purpose to provide the style you want to your texts.

After you have your font downloaded only 2 simple steps are left. First you have to copy the font. You can do this by selecting it and pressing simultaneously "ctrl" and "c" on your keyboard. Or simply right click. And then select copy.

With the font copied you now have 2 options for the final step. Either open the Fonts directory or use control panel. The Fonts directory is usually located in your root drive, in the Windows directory. All you have to do is paste the font in there. Either by pressing simultaneously "ctrl" and "v" or by doing a right click and selecting paste.

The other option is to open the control panel. You can open your control panel by going to start -> control panel. In the control panel just select the Fonts tab. And again simply paste the font file there.

You font is now ready to be used.

Developing new methods of telling the time accurately and precisely has developed to a new obsession amongst chronologists in the twenty first century. Since the development of the first atomic clocks in the 1950's with millisecond accuracy the race was started with organisation such as the US's NIST (National Institute for Standards and Time) and the UK's NPL (National Physical Laboratory) developing increasingly accurate atomic clocks.

Atomic clocks are used as the time source for high technologies and applications such as satellite navigation and air traffic control, they are also the source for time signals used by NTP servers to synchronise computer networks.

An NTP server works by continually adjusting the computers system clock to ensure it matches the time relayed by the atomic clock. In doing this the NTP server can keep a computer network to within a few milliseconds of atomic clock controlled UTC (Coordinated Universal Time).

However, as remarkable this technology may seem it appears Mother Nature has already been doing the very same thing with our own body clocks.

The human body clock is only just being understood by medical science (the study of which is called Chronobiology) but what is known is that the body clock extremely important in the functioning of our day to day lives; it is also highly accurate and works in a very similar way to the NTP server.

Whilst a NTP server receives a time signal from an atomic clock and adjust the system clocks on computers to match, our body clocks do the very same thing. The body clock runs in a circadian rhythm in other words a 24 hour clock. When the sun rises in the morning part of the brain that governs the body clock called the suprachiasmatic nucleus - which is located in the brain's hypothalamus, automatically corrects for the sun's movement.

In this way the human body clock adjusts for the darker winters and lighter months of the summer which is why you may find it more difficult to wake in the winter. The body clock adjusts itself every day to ensure it is synchronised to the rotation of the sun just as a NTP server synchronises a computer's system clock to ensure it is running accurately to its timing source - the atomic clock.
