Under normal conditions, oil and water do not mix. Moreoil facts.

Although it is still debated, it is largely recognized that the word 'chemistry' comes from an Egyptian word meaning 'earth'.

The use of various forms of chemistry is believed to go back as long ago as the Ancient Egyptians. By 1000 BC civilizations were using morcomplex forms of chemistry such as using plants for medicine, extracting metal from ores, fermenting wine and making cosmetics.

Things invisible to the human eye can often be seen under UV light, which comes in handy for both scientists and detectives.

Humans breathe out carbon dioxide (CO2). Using energy from sunlight,plantsconvert carbon dioxide into food during a process calledphotosynthesis.

Chemical reactions occur all the time, including through everyday activities such as cooking. Try adding an acid such as vinegar to a base sas baking soda and see what happens!

Above 4 C,waterexpands when heated and contracts when cooled. But between 4 C and 0 C it does the opposite, contracting when heaand expanding when cooled. Stronger hydrogen and oxygen bonds are formed as the water crystallizes into ice. By the time it's frozen it takup around 9% more space.

Often formed under intense pressure over time, a crystal is made up of molecules or atoms that are repeated in a three dimensional repeatipattern. Quartz is a well known example of a crystal.

Athletes at the Olympic Games have to be careful how much coffee they drink. The caffeine in coffee is a banned substance because it canenhance performance. One or two cups are fine but they can go over the limit with more than five. (update - as of 2004 caffeine has been taback off the WADA banned list but its use will be closely monitored to prevent future abuse by athletes.)

Computer Facts

Enjoy some great computer facts and interesting information about these amazing devices which play such an important role inour modern day lives.

Learn about parts of the computer such as the RAM, ROM and CPU as well as fun info about how we use computers to makeour lives easier and more enjoyable.

Early electronic computers, developed around the 1940s, were the size of a large room and consumed huge amounts of electrici ty. They wevastly different to the modern computers we use today, especially when compared to small and portable laptop computers.

Computers are programmed to carry out instructions. These instructions are usually very simple and require adding numbers together, movindata from one place to another etc.

A computer program can include as little as a few instructions to upwards of millions of instructions depending on the complexity of the progrModern applications such as word processors, web browsers and graphic editors take large teams of programmers a long time to complete.

A computers memory stores numbers in huge amounts of cells that are addressed and can be quickly accessed by the CPU to performcalculations. There are two main types of computer memory, ROM (read only memory) and RAM (random access memory). ROM contains pwritten software and data that the CPU can only read, while RAM can be accessed and written to at any time.

Computers interact with a number of different I/O (input/output) devices to exchange information. These peripheral devices include the keybomouse, display, hard drive, printer and more.

Computers are used to help link the world in the form of networks. Networked computers allow users to share and exchange data that is stordifferent locations. You may have heard of a local area network (LAN) or wide area network (WAN) which connects areas of various sizes. TInternet is a vast network of computers spanning the globe that allows users to access email, the World Wide Web and other applications.

Although we normally think of computers as the ones we use in our everyday lives to surf the web, write documents etc, small computers areembedded into other things such as mobile phones, toys, microwaves and MP3 players. We use computers all the time, often without evenknowing it!
