Condom


First off all i would like to give my sincerely apology for this article, although it is a taboo subject to be talking about and it could be a offensive to other religions but i think that this is an issue that have to be voice out.

A condom is a device most commonly used during sexual intercourse. It is put on a man's erect penis and physically blocks ejaculated semen from entering the body of a sexual partner. Condoms are used to prevent pregnancy and transmission of sexually transmitted diseases (STDs—such as gonorrhea, syphilis, and HIV). Because condoms are waterproof, elastic, and durable, they are also used in a variety of secondary applications. These range from creating waterproof microphones to protecting rifle barrels from clogging.
In the modern age, condoms are most often made from latex, but some are made from other materials such as polyurathane, or lamb intestine. A female condom is also available, most often made of polyurathane. As a method of contraception, male condoms have the advantage of being inexpensive, easy to use, having few side-effects, and of offering protection against sexually transmitted diseases. With proper knowledge and application technique—and use at every act of intercourse, users of male condoms experience a 2% per-year pregnancy rate.

Condoms have been used for at least 400 years. Since the nineteenth century, they have been one of the most popular methods of contraception in the world. While widely accepted in modern times, condoms have generated some controversy. Improper disposal of condoms contributes to litter problems, and the Roman Catholic Church generally opposes condom use.

The question is could it be that the invention of the condom is encouraging people to have sex before marriage , or with other people freely ?

Cars


Even when cars were still young, futurists began thinking about vehicles that could drive themselves, without human help. Everyday people think about how cars can be better in the future, Now at the start of the new century, it's worth taking a fresh look at this concept and asking how automation might change transportation and the quality of our lives.

Consider some of the implications of cars that could drive themselves.
• We might eliminate the more than ninety percent of traffic crashes that are caused by human errors such as misjudgments and inattention,
• We might reduce antisocial driving behavior such as road rage, rubbernecking delays, and unsafe speeds, thereby significantly reducing the stress of driving.
• The entire population, including the young, the old, and the infirm, might enjoy a higher level of mobility without requiring advanced driving skills.
• The luxury of being chauffeured to your destination might be enjoyed by the general populace, not just the wealthiest individuals, so we might all do whatever we like, at work or leisure, while traveling in safety.
• Fuel consumption and polluting emissions might be reduced by smoothing traffic flow and running vehicles close enough to each other to benefit from aerodynamic drafting.
• Traffic-management decisions might be based on firm knowledge of vehicle responses to instructions, rather than on guesses about the choices that drivers might make.
• The capacity of a freeway lane might be doubled or tripled, making it possible to accommodate growing demands for travel without major new construction, or, equivalently, today's level of congestion might be reduced, enabling travelers to save a lot of time.

So do you think that in the future that the cars that we drive , can drive themselves ?

Paper


Written communication has been the center of civilization for centuries. Most of our important records are on paper. Although writing has been around for a long time, paper hasn't.

In fact, putting thoughts down in written form wasn't always easy or practical. Early people discovered that they could make simple drawings on the walls of caves, which was a great place for recording thoughts, but wasn't portable.

Imagine spending hours scratching a message into a heavy clay tablet and then having to transport it. That's exactly what the Sumerians did around 4000 B.C. Although this form of written communication was now portable, it still wasn't practical because of its weight.

For centuries, people tried to discover better surfaces on which to record their thoughts. Almost everything imaginable was tried. Wood, stone, ceramics, cloth, bark, metal, silk, bamboo, and tree leaves were all used as a writing surface at one time or another.

The word "paper" is derived from the word "papyrus," which was a plant found in Egypt along the lower Nile River. About 5,000 years ago, Egyptians created "sheets" of papyrus by harvesting, peeling and slicing the plant into strips. The strips were then layered, pounded together and smoothed to make a flat, uniform sheet.

No major changes in writing materials were to come for about 3,000 years. The person credited with inventing paper is a Chinese man named Ts'ai Lun. He took the inner bark of a mulberry tree and bamboo fibers, mixed them with water, and pounded them with a wooden tool. He then poured this mixture onto a flat piece of coarsely woven cloth and let the water drain through, leaving only the fibers on the cloth. Once dry, Ts'ai Lun discovered that he had created a quality writing surface that was relatively easy to make and lightweight. This knowledge of papermaking was used in China before word was passed along to Korea, Samarkand, Baghdad, and Damascus.

By the 10th century, Arabians were substituting linen fibers for wood and bamboo, creating a finer sheet of paper. Although paper was of fairly high quality now, the only way to reproduce written work was by hand, a painstaking process.

By the 12th century, papermaking reached Europe. In 1448, Johannes Gutenberg, a German, was credited with inventing the printing press. (It is believed that moveable type was actually invented hundreds of years earlier in Asia.) Books and other important documents could now be reproduced quickly. This method of printing in large quantities led to a rapid increase in the demand for paper.

Today paper is so common that we take it for granted , and it is hard to envisage what the world was like without it. The world that we are living in is in turmoil and cutting down all those tree's doesn't help the eco-system at all, it would take a rough average of 24 tress to produce a ton of printing and writing paper and we can estimate that it takes about 12 trees to make a ton of groundwood and newsprint.

Can you imagine how many trees has to cut down in order to just give us something to write , my idea is in the near future instead of carrying a lot of papers and documents around , we should implement in the system that all documented things are to be put in USB flash drive (pen drive) and it would be easier to carry around , so what do you think of my idea , would it be practical in the near future ?

Telephone


The telephone is a telecommunications device which is used to transmit and receive sound ( most commonly speech). Most telephones operate through transmission of electric signals over a complex telephone network which allows almost any phone user to communicate with almost anyone. The telephone gave those who used it the ability to carry on a live conversation in real time over most any distance. In business and personal relationships conversation is necessary to make things happen. And for those in business and professional relationships, or those in personal relationships , the phone provides the link for instant voice communication in real time , complete with the subtle sound cues of "normal" speech (cause that's what is it ) that convey a fuller meaning than just written or texted communication . And the phones pushes the telegraph out of the picture , who knows morse code anymore ?

In the 21st century the telephone is an important asset to our daily life, we carry them all around 24 hours , but can you imagine on tomorrow's innovation that the telephone can be embedded in your skull and assigned a number , we could all end up with a wireless implant allowing us to communicate interpersonally with whomever we wanted . The future is not a complicated cellular phone that takes a PhD to figure out , instead voice telephony is something very simple where you can just think of someone you want to call and they're on the phone. It's probable that the biggest change will be something that isn't yet self-evident( as was the case with mobile phones 10 years ago)

So the question is can this idea be practical , a microchip embedded in people's skull so that contacting other people would be easier ? . To understand more about this idea please visit this website ( http://www.abc.net.au/science/lcs/mobiles.htm) Thank you .

Computer


My first article would be the invention of the computer , technically a computer is a programmable machine . This means it can execute a programmed list of instructions and respond to new instructions that it is given. Today, however the tern is most often used to refer to the desktop and laptop computers that most people use. When referring to a desktop model, the term "computer" technically only refers to the computer itself , not the monitor, keyboard, and mouse . Still it is acceptable to refer everything together as the computer . If u want to be really technical , the box that holds the computer is called the "system unit".

(sources from :http://www.techterms.com/definition/computer)

Modern computers are electronic and digital. The actual machinery , wires , transistors and circuits , is called hardware ; the instructions and data are called software.

All general -purpose computers require the following hardware components:
  • Memory: Enables a computer to store, at least temporarily , data and programs.
  • Mass Storage Device: Allows a computer to permanently retain large amounts of data. Common mass storage devices include disk drives and tape drives.
  • Input Device: Usually a keyboard and mouse , the input device is the conduit through which data and instructions enter a computer.
  • Output Device: A display screen, printer , or other device that lets you see what the computer has accomplished.
  • Central Processing Unit (CPU): The heart of the computer, this is the component that actually executes instructions.
(sources from :http://webopedia.internet.com/term/c/computer.html)

Some of the major parts of a personal computer ( or PC) include the motherboard , CPU , memory ( or RAM) , hard drive , and video card . While personal computers are by far the most common type of computers today , there are several other types of computers. For example , a "minicomputer" is a powerful computer that can support many users at once. A "mainframe' is a large , high-powered computer that can perform billions of calculations from multiple sources at one time. Finally , a "supercomputer" is a machine that can process billions of instructions a second and is used to calculate extremely complex calculations.

Computers over the past years have become a vastly popular household item. The luxury of emailing messages as opposed to charging up the phone bill is more appealing. Checking news , weather , and sports via the internet is a convenience that many are taking advantage of. Our children's lives are already getting influenced by technology , and this is just the beginning . Computers and Internet are here to stay and software titles targeting young children to increase. Today, we find computers in use everywhere , whether we go to reserve a train ticket or to a bank . This is because it is faster and helps us complete our work without mistakes/errors . So parents too have realized the need to help their children develop strong
computer skills.

All the above discussion is that we use our computer in almost everything in our daily life , but my question here is do we rely to much on our computers that if one day the system in our computers shut down what would happen ?

Please comment , thank you
