As more and more people are becoming at ease using their computers at school, home or in the office it’s merely a matter of time before they meet a computer virus. Here are our top instructions to guard you from computer viruses. Use a high quality anti-virus program. There are many diverse anti-virus computers programs on the market some of them are better than others. Look to trustworthy computer magazines or websites for ratings to aid you locate the one that matches your requirements. Always use your anti-virus software. Keep your antivirus programs up to date. Most programs come with a yearly subscription make sure you take benefit of the updates. More advanced programs allow you to schedule updates or complete system scans for “off hours” like 2AM when you aren’t expected to be using your computer. Keep your computer up to date. From time to time operating systems fall victim to security holes or issue updates. Make sure you check occasionally to make sure you are running steady latest versions of your software. If you use floppy disks or USB drives on public computers like your school computer lab, Kinko’s, or even digital photo printing store make sure you scan them for viruses. Public computers are notorious for not being up to date and properly protected. Be wary of email attachments. Never open attachments from people you weren’t expecting. Also be careful of attachments from people you know but weren’t expecting. Many computer viruses replicate themselves by reading the contacts from an infected computer. Use text email if possible. Use downloaded freeware and shareware files or software with caution. Try to download them from popular reputable sources that scan the programs before they are uploaded. To make sure you are safe scan the program before you install it on your computer. Be wary of links in IM or instant messaging software. Don’t accept invitations from people you don’t know and never click a link from someone you don’t trust, they can easily redirect you to another website that will try to install a virus on your computer system

Look outside the window and you may see the leaves of a tree falling down.
There will some students who would not even have noticed the leaves falling. Some may have seen the falling leaves but this not register what they saw. Other may admire the beauty of the falling leaves .
Still others may ask some questions about the falling leaves;
• Why did the leaves fall down and not to fly up ?
• Would the larger leaves fall faster ?
• Would a heavier leaf fall faster?


In fact there are a thousand and one questions you can as about the falling leaves.
The leaves of a tree falling down is one of the events that happened around us everyday
Event –something that happens, in this case the leaves falling from the tree. An action, with a beginning and an end.


Physical phenomena are always unfolding before us. By asking questions we can focus on the aspect we are interested in. By making observations and careful measurements we can gather the necessary data that will help us in our search for the answers to our question. Experiment have to properly planned and carried out to verify the answer we seeks.
In physics we learn about making connections. We know that when released the object,it fall down towards the earth. We observe that the Moon goes round the Earth. Is there any connection between the two phenomena ?


Physics is a branch of science centered on the study of the matter, energy, and the connection between them.ExampleThree students have performed an experiment in which they tested the sinking and floating behavior of three objects , each of the same volume but of difference mass. They found two of the object sank while the third object floated. Consider the following discussion among them.

Q. Why should I have to study physics if I'm going to be a doctor - lawyer - etc?
Physics, as a discipline - especially at an undergraduate level, teaches many things that are important in all walks of life:

1) Problem Solving skills - the typical physics course is more problem solving based than any other subject (except perhaps mathematics) and the problems are often more practical. If you want to be a doctor, say, skill at quickly thinking about the problems of "what is wrong with this patient" could mean the difference between life and death.

2) Real World Familiarity - Freshman physics courses tend to teach about the every-day, real, world. You learn about how things move, how they fall, what friction means, what constraints conservation of energy and momentum can put on a system.

3) Relevant information - Physics is directly relevant to the core of many fields which might seem separate at first glance.

Engineers build bridges, but they need to understand the forces involved and how bridges react to stress in order to build safe ones.
Biologists look at proteins and DNA - the structures of which are measured using diffraction techniques developed by physicists, and only really understood through physics. Biologists also use light and lasers to make fluorescence measurements to keep track of the chemicals present - physics illuminates the devices, lenses, microscopes and the very colors of the dies used!

As you can see, there are many good reasons to study physics, no matter what your career goal might be - but the most important is that physics is constantly unveiling new facts about our universe - from the very small, like new semiconductors and superconductors, to the very large, like black holes and galaxies - do you want to understand what is coming, or do you want to be left behind?
