sir, this is a very nice and important topic for our natural science. I am too much interested to know about this type of informative topics.

Science Discussion Forum / What is Tide
« on: April 25, 2012, 09:45:34 PM »
Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the Moon causes the oceans to bulge out in the direction of the Moon. Another bulge occurs on the opposite side. Sir Isaac Newton (1642 -1727) was the first person to explain tides scientifically. In 1687, Newton explained that ocean tides result from the gravitational attraction of the Sun and Moon on the oceans of the Earth (Sumich, 1996). There are two types of tide, namely, lunar tide and solar tide. Generally the Tide which is created by the Moon is called lunar tide and the Tide which is created by the Sun is called solar tide.

The terms gravity and gravitation are often used to explain the same thing, but there is a definite difference between the two. Gravitation is the attractive force existing between any two objects that have mass. The force of gravitation pulls objects together. Gravity is the gravitational force that occurs between the Earth and other bodies. Gravity is the force acting to pull objects toward the Earth. Since gravitational force is happening to all objects in the universe, from the largest galaxies down to the smallest atoms, it is often called universal gravitation. Gravitation is actually a very weak force. The pull is too weak to be felt between two people and it is not even strong enough to pull together two lumps of lead placed right next to each other. It is only when one of the masses is the size of a planet that we can feel the force of gravity. The huge gravitational force of our nearest star, the Sun, holds together the eight planets of our Solar System. The planets move through space at speeds that just balance the Sun’s gravitational pull, so they are locked into a permanent orbit around the Sun. Moons orbit planets, and satellites and spacecraft orbit the Earth, in the same way. Satellites are not defying gravity in circling endlessly around the Earth, it is just that they are moving so fast around the Earth that gravity never brings them any closer. The force holding objects to the Earth's surface depends not only on the Earth's gravitational field but also on other factors, such as the Earth's rotation. The Earth’s gravitational pull extends out into space in all directions. The further we move away from the centre of the Earth the weaker the force become. The measure of the force of gravity on object is the weight of that object. The weight of an object changes depending on its location in the universe.

Common Forum / At a Glance "De Morgan"
« on: April 25, 2012, 10:55:31 AM »
De Morgan, Augustus (du môr'gun), 1806–71, English mathematician and logician, b. India. A noted teacher, he was professor of mathematics (1828–31, 1836–66) at University College (now part of the Univ. of London) and a founder and first president (1865) of the London Mathematical Society. Known as a reformer of logic, he developed a new logic of relations that he summarized in Syllabus of a Proposed System of Logic (1860). His works include An Essay on Probabilities (1838), Formal Logic (1847), Trigonometry and Double Algebra (1849), and A Budget of Paradoxes (1872).

Speech / George Washington

George Washington's First Inaugural Address
Given in New York, on Thursday, April 30, 1789

Fellow-Citizens of the Senate and of the House of Representatives:

Among the vicissitudes incident to life no event could have filled me with greater anxieties than that of which the notification was transmitted by your order, and received on the 14th day of the present month.

On the one hand, I was summoned by my country, whose voice I can never hear but with veneration and love, from a retreat which I had chosen with the fondest predilection, and, in my flattering hopes, with an immutable decision, as the asylum of my declining years—a retreat which was rendered every day more necessary as well as more dear to me by the addition of habit to inclination, and of frequent interruptions in my health to the gradual waste committed on it by time.

On the other hand, the magnitude and difficulty of the trust to which the voice of my country called me, being sufficient to awaken in the wisest and most experienced of her citizens a distrustful scrutiny into his qualifications, could not but overwhelm with despondence one who (inheriting inferior endowments from nature and unpracticed in the duties of civil administration) ought to be peculiarly conscious of his own deficiencies. In this conflict of emotions all I dare aver is that it has been my faithful study to collect my duty from a just appreciation of every circumstance by which it might be affected. All I dare hope is that if, in executing this task, I have been too much swayed by a grateful remembrance of former instances, or by an affectionate sensibility to this transcendent proof of the confidence of my fellow-citizens, and have thence too little consulted my incapacity as well as disinclination for the weighty and untried cares before me, my error will be palliated by the motives which mislead me, and its consequences be judged by my country with some share of the partiality in which they originated.

Such being the impressions under which I have, in obedience to the public summons, repaired to the present station, it would be peculiarly improper to omit in this first official act my fervent supplications to that Almighty Being who rules over the universe, who presides in the councils of nations, and whose providential aids can supply every human defect, that His benediction may consecrate to the liberties and happiness of the people of the United States a Government instituted by themselves for these essential purposes, and may enable every instrument employed in its administration to execute with success the functions allotted to his charge. In tendering this homage to the Great Author of every public and private good, I assure myself that it expresses your sentiments not less than my own, nor those of my fellow-citizens at large less than either. No people can be bound to acknowledge and adore the Invisible Hand which conducts the affairs of men more than those of the United States. Every step by which they have advanced to the character of an independent nation seems to have been distinguished by some token of providential agency; and in the important revolution just accomplished in the system of their united government the tranquil deliberations and voluntary consent of so many distinct communities from which the event has resulted can not be compared with the means by which most governments have been established without some return of pious gratitude, along with an humble anticipation of the future blessings which the past seem to presage. These reflections, arising out of the present crisis, have forced themselves too strongly on my mind to be suppressed. You will join with me, I trust, in thinking that there are none under the influence of which the proceedings of a new and free government can more auspiciously commence.

By the article establishing the executive department it is made the duty of the President “to recommend to your consideration such measures as he shall judge necessary and expedient.” The circumstances under which I now meet you will acquit me from entering into that subject further than to refer to the great constitutional charter under which you are assembled, and which, in defining your powers, designates the objects to which your attention is to be given. It will be more consistent with those circumstances, and far more congenial with the feelings which actuate me, to substitute, in place of a recommendation of particular measures, the tribute that is due to the talents, the rectitude, and the patriotism which adorn the characters selected to devise and adopt them. In these honorable qualifications I behold the surest pledges that as on one side no local prejudices or attachments, no separate views nor party animosities, will misdirect the comprehensive and equal eye which ought to watch over this great assemblage of communities and interests, so, on another, that the foundation of our national policy will be laid in the pure and immutable principles of private morality, and the preeminence of free government be exemplified by all the attributes which can win the affections of its citizens and command the respect of the world. I dwell on this prospect with every satisfaction which an ardent love for my country can inspire, since there is no truth more thoroughly established than that there exists in the economy and course of nature an indissoluble union between virtue and happiness; between duty and advantage; between the genuine maxims of an honest and magnanimous policy and the solid rewards of public prosperity and felicity; since we ought to be no less persuaded that the propitious smiles of Heaven can never be expected on a nation that disregards the eternal rules of order and right which Heaven itself has ordained; and since the preservation of the sacred fire of liberty and the destiny of the republican model of government are justly considered, perhaps, as 'deeply', as 'finally', staked on the experiment entrusted to the hands of the American people.

Besides the ordinary objects submitted to your care, it will remain with your judgment to decide how far an exercise of the occasional power delegated by the fifth article of the Constitution is rendered expedient at the present juncture by the nature of objections which have been urged against the system, or by the degree of inquietude which has given birth to them. Instead of undertaking particular recommendations on this subject, in which I could be guided by no lights derived from official opportunities, I shall again give way to my entire confidence in your discernment and pursuit of the public good; for I assure myself that whilst you carefully avoid every alteration which might endanger the benefits of an united and effective government, or which ought to await the future lessons of experience, a reverence for the characteristic rights of freemen and a regard for the public harmony will sufficiently influence your deliberations on the question how far the former can be impregnably fortified or the latter be safely and advantageously promoted.

To the foregoing observations I have one to add, which will be most properly addressed to the House of Representatives. It concerns myself, and will therefore be as brief as possible. When I was first honored with a call into the service of my country, then on the eve of an arduous struggle for its liberties, the light in which I contemplated my duty required that I should renounce every pecuniary compensation. From this resolution I have in no instance departed; and being still under the impressions which produced it, I must decline as inapplicable to myself any share in the personal emoluments which may be indispensably included in a permanent provision for the executive department, and must accordingly pray that the pecuniary estimates for the station in which I am placed may during my continuance in it be limited to such actual expenditures as the public good may be thought to require.

Having thus imparted to you my sentiments as they have been awakened by the occasion which brings us together, I shall take my present leave; but not without resorting once more to the benign Parent of the Human Race in humble supplication that, since He has been pleased to favor the American people with opportunities for deliberating in perfect tranquillity, and dispositions for deciding with unparalleled unanimity on a form of government for the security of their union and the advancement of their happiness, so His divine blessing may be equally 'conspicuous' in the enlarged views, the temperate consultations, and the wise measures on which the success of this Government must depend.

Voltage Pictures, the production studio behind the Oscar-winning film The Hurt Locker, has filed a new lawsuit in a federal court in Florida, according to TorrentFreak. The studio’s latest complaint targets at least 2,514 alleged BitTorrent users, whom Voltage Pictures claims pirated the film and cost the studio millions. The company last year filed a joint lawsuit against more than 30,000 alleged BitTorrent users who illegally downloaded the film. The case closed this past December, with Voltage Pictures collecting an undisclosed number of settlements. The studio’s latest suit looks to obtain a subpoena that will order ISPs to reveal the identities of the defendants. The alleged pirates will then be offered a settlement of about $3,000, the report claims. All of the defendants allegedly downloaded the film in 2010 and are Charter Communications subscribers.


Thanks Susmita, for your important post. I am also comply with your opinion. I hope all of us should strictly maintain this rule in the examination hall.

We all think that we know every thing about the computer but this isn't right why we will tell you because the computer is an open source technology and how we want to know every thing a bout it we will tell you here.

1. Work on the computer and figure out what does what. Such as on a Mac computer what happen when you hit a picture with two fingers on the trackpad. If you have a friend who likes fiddling with machines, feel free to ask him/her for tips or explanations on certain components on the computer you are wondering about, such as how they work.

2. Go to the Internet and type in something on Google like "computers for beginners" or go to a store and buy the book "Computers for Dummies".

3. Experiment with what you know and thus learn what you don't know.

4. Study computer languages such as C++ and Python. These languages will help you making programs and websites.

5. Go to a computer institute and sign in to learn things that will help you such as the ISDL and other great things.


# Don't use the computer for a long, long time. Some computers can shut down if you have them on
too long or if they get too hot.

# Use the computer after you finish your homework and work on studying programming.
# Take a break from time to time.
# Download an antivirus program to secure your computer from viruses.

Common Forum / Be Nice to Your Family
« on: April 25, 2012, 10:15:14 AM »
You feel that your family deserve some respect and happiness. Well, now you know how?

1. Don't raise your voice.    This will only anger your other family members. Even if you are an adult, keep in mind that when you raise your voice, it usually ends in an argument.

2. Help your family out by doing small chores around the house. If you are a kid or teen, make sure you do all of your chores and complete them thoroughly.

3. Earn Winky Points.          Buy someone a gift to show how much you care about them, Not necessarily just to get them to be nice to you.

4. Be open.                       Share your ideas and opinions. With that there would be better communication resulting to a more harmonious relationship. Talk. When you have good, long conversations with family members, it shows them that you care and are interested in their lives. But when you talk, talk in a kind and unselfish way.

5. Be respectful.                When you are respectful, you earn respect of others, and when there is respect, there are no arguments.

6. Be loving.

7. Don't be violent.            Punching and kicking siblings will make them mad at you.

8. Always be nice. Don't be overly nice or you will look transparent.

IT Forum / Google Chrome vs. Firefox
« on: April 24, 2012, 08:27:47 PM »
As of February 2012, Firefox and Chrome are neck-and-neck in the race for being the most popular web browser in the world, both with about 36 percent market share, according to statistics from W3Schools. While Firefox claims a slight lead over Chrome in terms of popularity, both browsers offer features that make them worth taking for a test drive. Important factors such as speed and security are more ore less comparable for the two browsers, so your ultimate decision may come down to which one offers the customizations or features that you need to perform your desired tasks.

Structure: When it comes to structure, Chrome and Firefox ascribe to two different schools of thought. Firefox, owned by Mozilla, is an open-source project with many contributors, whereas Google's Chrome is closed-source and documentation is kept private. That's not to say that Google doesn't invite open-source projects; but its open-source browser is Chromium, not Chrome. What this means for the browser experience is that Firefox has potentially had "more cooks in the kitchen" working out potential bugs. Behind the scenes of the two browsers are two different browser engines -- which handle how the browser manages your requests; Firefox relies on the Gecko browser engine, while Chrome is based on Webkit. While both are equally viable, Webkit -- also used in Apple's Safari browser -- is more often used in mobile devices. For the future of browsing, this may be a big factor in overall viability. Firefox is also available on more operating systems, including Mac OS X, Linux, Windows, Sun Solaris, Open BSD and Free BSD. Chrome, meanwhile is available only for Linux, Windows and Mac; other operating systems must use Chromium.

Security: An important aspect for any browser is its level of security. According to a study conducted by Accuvant, Chrome emerged as the most secure browser, over both Firefox and Internet Explorer -- with Internet Explorer coming in over Firefox. Chrome scored the highest marks for having the highest number of anti-security measures. While both Firefox and Chrome employ"sandboxing" to isolate potentially harmful attacks on your computer, Chrome employs it more often, for more processes. Likewise, Chrome offers more security features for plug-ins, and automatically disables them when they become out-of-date.

Extensions: When it comes to extensions to the browser, Firefox is the clear leader in the number of options. Likewise, Firefox comes with a number of extensions already built in, which could lead to a slower initial load time for the browser. If you're looking for the fastest load time, Chrome may be your choice. If you want a wider array of features to add in to your browsing experience, Firefox may be the answer. At present, Firefox's extension options include more security add-ons than Chrome. And since Firefox has been around longer, there's also been more time for finding and solving security issues.

Tabs: Another distinguishing feature of Chrome is its separate processes for each window and tab. When you open a new tab or window, Chrome separates that tab or window in to its own process. What this means for you is that if you're experiencing a slow load time on one site, it's not going to slow down your experience in other windows and tabs. Likewise, if one tab crashes, it won't crash the entire browser. Firefox, meanwhile, continues to employ the more traditional method of processing tabs, in which are all are tied together. In terms of security, this process separation employed by Chrome may make it more secure overall.

IT Forum / Restrict Hard Drives in Windows 7
« on: April 24, 2012, 08:23:58 PM »
You can restrict access to a hard drive in Windows 7. This is useful if you have files on a hard drive that you do not want anyone else to access. A user will have to know your username and password to access the hard drive. You can also change other settings, such as only allowing a user to view a file and not change it.

1. Log on to your computer with an account with Administrator rights. Click "Start," type "user" (without quotes) in the automatically selected "Search programs and files" search box and click "User Accounts." Click "Manage another account."

2. Click "Create a new account," if you need to create a user account for other people that will be using the computer. If you already have another account set up, go to the next step. You need to have at least your user account and another one set up to restrict access to a drive. Type a name for the user and click "Create Account."

3. Click "Start" and "Computer." Right-click the name of the hard drive you want to restrict access to. Click "Properties."

4. Click the "Security tab" in the "Properties" window that opened. Click "Edit" and "Add" in the "Select Users or Groups" window that opened.

5. Type the name of the other user account on your computer. Click "OK." Uncheck the boxes to the left of any options that you do not want the user to have available. Check the "Deny" box for "Full control" to disable all control from the user for files on the hard drive.

6. Click "OK," "Yes" and "OK." Close any open windows. Click "Start," log off of your account and log on as the other user to test your settings.

7. Click "Start," "Computer" and double-click the name of the hard drive you restricted access to. A window indicating that "Access is denied" is shown. Close the window and log off the computer.
