In this twenty-first century, human make the world. As everyone can see, this is a modern, advance century. Throughout history, people have made inventions that changed the world. Some got lucky and stumble on something, some actually set out to make something, and still others improved upon existing technology to create something revolutionary, same as now. Scientist and experts have discovery and created awesome inventions which shaped the newest century such as artificial heart and liver, retinal implant for blind, YouTube, Apple’s products, e-books, GPS and also Amphicars.
Man rely on internal organ to take out regulations and work to keep alive but nowadays diseases such as cardiovascular, liver cancer, heart attack and heart failure have overwhelmed throughout the world but transplantation is not always usable and there is difficulty and risk to find a suitable ‘replacement’. The pumping organ is the most precious gift. At first there is no replacement but the first ever artificial heart was approved in 2004. It is made up of plastic and titanium.
Artificial hearts are typically used in order to bridge the time to heart transplantation, or to permanently replace the heart in case transplantation is impossible. This amazing invention has created numerous miracles and it brings hope to the patients. There have been few cases when people were declared too ill by the doctor for heart transplant but artificial heart did wonders for them. The obvious benefit is to minimize the need for heart transplant, because the demand for organs always greatly exceeds supply.
Nevertheless one of the most vital organ which regulates, removes toxin, manufactures protein and also helps to maintain the ph value of our internal body, the liver has its replacement too, the artificial liver. In some cases, it is used to give the damaged liver sufficient time to team. A synthetic replacement for the heart or even liver remains one of the long-sought holy grails of modern medicine. Another one notable invention is a retinal implant for the blind. A retinal implant is a biomedical implant technology currently being developed by a number of private companies and research institutions worldwide.
The implant is meant to partially restore useful vision to people who have lost theirs due to degenerative eye conditions such as retinitis pigmentosa or macular degeneration. Patients with these diseases become blind because of loss rods and cones, which are the only photoreceptive elements in the eye. The Retinal Implant Research Group has developed a microelectronic retinal implant to restore vision to patients with age-related macular degeneration and blindness.
It is known as ‘electric eye’, which implant a microchip into the patient’s eyeball. Besides that, experts has fitted three patients with this new device and successfully, they were able to see shapes and objects, and one was able to walk around a room by himself, approach people, read a clock face and differentiate between seven shades of gray. In the past, retinal implants required a small external camera to capture light; now, the new advance in technology captures natural light from eyes to help the patient see.
To go from being completely blind for many years, to being able to read a few letters and see shapes is an amazing step and it has brighten future for blind. We have to be grateful and appreciate their efforts, because of those experts and scientist, this 21th century is full of hopes. From the side of mass media, a site that enables free watch of videos or clips through internet has gained their popularity throughout the world in a mean time. There should be an answer wandering in your mind, which is ‘YouTube’, this amazing website.
YouTube was created by Steve Chen, Chad Hurley and Jawed Karim. YouTube is a premier worldwide destination to watch and share original videos on www. youtube. com. Registered users can upload and share their video clips or even share their opinions towards the clips. Everyone can watch videos on YouTube. People can see first-hand accounts of current events, find videos about their hobbies and interest, and discover the quirky and unusual. As more people capture special moments on video, YouTube is empowering them to become the broadcasters of tomorrow.
Recently, YouTube enables video embedding that allows YouTube videos to be placed on non-YouTube pages and even offer the users an opportunity to download those videos through some programs. Therefore, visit YouTube has been the most famous hobby among the younger during their leisure time even the older addicted to it due it is easily to conduct and watch online video with just a click on the titles. Therefore, it is how it shaped 21th century, people don’t just depend on cinema or TV program but they do stick in front of the computer to watch online videos.
Let’s give a round applause to Apple Inc! Apple always brings up the hottest wave in the world and obviously, 21th century is all about Apple’s product no matter their best-known hardware products such as iPhone, iPad, Mac Book and iPod or their awesome software, iTune is shocking the worldwide market. When people talk about technology, but Apple was a marketing company and it was the marketing company of the decade. When Apple introduced iPod, it became the market leader in portable music players. It has evolved to include various models targeting the wants of different users.
The hard drive-based iPod Classic, the compact iPod Nano, the ultra-compact iPod Shuffle and the touch screen iPod Touch was evidences of its effort to completely satisfy the market. These amazing inventions have totally replaced the old-style radio, Discman and whatever disc player. This is because it is small and convenient to bring everywhere at anytime. Currently, touch screen is the hottest topic among crowds and everyone is using the touch screen. Why is it so attractive? The touch screen has two main attributes.
First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in hand. Besides that, they play a prominent role in the design of digital appliances and widely used in PDA, mobile phones, satellite navigation devices and video games. Absolutely, with the modern wave of touch screen, iPhone was introduced on 2007. It is a line of Internet and multimedia-enabled smartphones designed.
Its multi-function also impressed people such as video camera, camera phone with text-messaging and visual voicemail, a portable media player, and an Internet client with e-mail, web browsing and both Wi-Fi and 3G connectivity. Its Apple applications have diverse functionalities too, including games, references, GPS navigation, social networking, security and advertising for television shows, films, and celebrities. Previously, iPhone is a signature of wealthy people but now it is an identity of this modern decade’s people. Haven’t get one?
Then, you are really far away behind this advance century. For a better exposure of education, in our era, though, has come the development of e-books. For 40 years e-books have been available to view on computers or other digital devices. It is a text and image-based publication. E-book pioneer Project Guttenberg has developed thousands of titles in electronic format, titles in the public domain that could be made available for free to those who want to read them on a computer. Now, they are everywhere, from the Amazon Kindle to the Barnes and Noble Nook to the Sony Reader and many more.
We can buy books online, download them to our personal computers, and move them to our e-readers. And now we can purchase books directly with our e-readers via wifi connections. We can also do something else pretty cool, we can borrow digital books from our libraries and read them on our computers and on our e-readers. Furthermore, e-book websites can include the ability to translate books into many different languages, making the works available to speakers of languages not covered by printed translations.
Depending on the device, an e-book may be readable in low light or even total darkness. Many newer readers have the ability to display motion, enlarge or change fonts, use Text-to-speech software to read the text aloud for visually impaired, partially sighted, elderly or dyslectic people, search for key terms, find definitions, or allow highlighting bookmarking and annotation. Actually, e-book do helps a lot in 21th century. Besides promote reading, it is environmental friendly as it reduces the uses of paper which indirectly save the trees.
E-books are good for paper book publishing. By setting an example for diversity and freedom of expression, e-books may motivate the stagnant book publishing industry towards the renewal of small presses, the end of the blockbuster-bestseller publishing mentality, and a healthier balance between the needs of commerce and culture. It is easily updateable, portable, searchable, printable and it defy time too as it can be delivered almost instantly. E-books are transported to you faster than overnight shipping, in minutes or in seconds.
Now, everyone can easily use the package, paper and Web with books and magazines on reader which can easily tuck into your bag to go anywhere, anytime, a thousand books without the lumps. How do you actually survive when you are located at a foreign place? To try to find out the destination with a map and some luck? While this new world improves day by day, global positioning system (GPS) was introduced. GPS was originally developed as a military navigation tool. However the technology has grown along with a sub set of supporting technologies to serve other requirements within consumer budgets.
The principle behind GPS is very simple. It works by providing a set of geographical coordinates such as a place’s latitude, longitude and elevation on Earth. The GPS device also gives out very accurate time. The basic functionality of GPS technology is limited to receiving satellite signals and calculating position information. Things like navigation systems, tracking devices, surveying and mapping instruments are simply different applications of the technology. By the way, GPS navigation has widely used by people and it brings convenience to them.
This is due to its awesome capabilities. It contains maps, which may be displayed in human readable format via text or in a graphical format, provides suggested directions to a human in charge of a vehicle or vessel via text or speech, directions directly to an autonomous vehicle such as a robotic probe and even the information on traffic conditions, either via historical or real time data, suggesting alternative direction and also information on nearby amenities such as restaurants, fueling stations, gardens and shopping heaven for women.
In addition, dedicated devices have various degrees of mobility. Hand-held, outdoor, or sport receivers have replaceable batteries that can run them for several hours, making them suitable for hiking, bicycle touring and other activities far from an electric power source. Their screens are small, and some do not show color, in part to save power. Cases are rugged and some are water resistant. Hence, we can actually survive in first-visit places even if those are rural country with this GPS technology.
Since the past, humans like to imitate animals. They hope to be run as fast as a leopard hence many vehicles like cars, LRT, MRT and busses are created; they dreamed to fly like a bird and yet airplanes are invented; to swim like fishes, ships or even submarine are introduced. Now, even amphibians are imitated! The most notable invention in 2003 was the Amphicar. Compared to most boats and cars, its performance was modest.
Nevertheless, it is still among the most successful amphibious civilian autos of all time, and still often prized and preserved as novelty collectible automobiles today. One of the examples is the car-boat. It is built to operate as both a car and a boat. On land, a car boat looks and runs like a car. In the water, it still looks like a car, but it floats and can be propelled. Besides that, it does move fast in both. To create a car boat, wheels are added to a boat, or create a car that floats.
Car boats range from homemade versions built by hobbyists to specially manufactured high-end models. Definitely, car boats are waterproof. A car boat requires welded seams or waterproof marine sealant on the seams to prevent leakage. The bottom of a car boat is shaped like a hull. A car boat’s volume is bigger than its displacement in order to float. In water as well as on land, the Amphicar steered with the front wheels, making it less maneuverable than a convenient boat.
A well-maintained Amphicar does not leak at all and can be left in water, parked at a dock side, for a long duration. Absolutely, this amazing invention does shape the world into the modest style. We are now getting into 21st century. The last 100 years or so have really seen the rise of some of the greatest inventions that have ever come our way. The inventions of the twenty-first century will no doubt continue to give us things that we need in order to thrive. It will be interesting to see where the new agent technology that we are now living in will take us.
