In some progressive countries, like Japan, electric power is used in almost all the factories, a power cut in one day could lead to the deadlock. For this reason, electric power is really useful in production as well as the growth of industries. The second invention I believe that it has great impacts on our social life is the creation of computer.
It would actually be difficult to say when the first computer was made but Charles Babbage was the first one to conceptualize it. In fact, computer is the extremely important Invention because it helps us to display and save information; this invention is also applied in almost all fields. In olden times, storing information had many disadvantages.
You had to write information on the papers and then store them a certain place. As a matter of fact, the data could be lost after a long time due to old paper, wood-borer. However, today it becomes easier and more convenient with computer. You just type the information you need, save it and it is done. You do not need many shelves to save data anymore. On the other hand, you can edit them as you like and you can save them as many files as you want.
PC actually is utilized in almost all fields such as studying, working and entertaining. For instance, people can use computer for presentation, planning a project, playing videogames, watching TV and listening to music. The last but not least is the invention of aircraft. All of us cannot deny the creation of aircraft has changed the way of our traveling. The airplane is not only one of the greatest inventions in the 20th century, but also one of the most wonderful scientific creations of the human history at large.
This mean of transport made it possible for people to work in places miles away. The existing of aircraft has turned long and exhausting journeys into a trip completed within hours. Also, the people from divergent parts of the world could travel from one region to the other quickly, thereby exchanging different aspects in social and cultural experiences. It is one of the crucial factors that help business expand to global market.
Furthermore, children can attend school in distant countries. In the past, this was impossible. Hence, the children of today are better educated than those of the past. Thanks to the creation of aircraft, human beings became more dynamic, they are able to do business in foreign lands and visit various countries all over the world. Scientific inventions have made this world worth living. They help our life become more comfortable and convenient. And three of the inventions modifying deeply the way we live are the creations of electricity, computer and aircraft.
We can sure that these changes will not stop there, these inventions have just built the foundation for the future scientists to create more and more inventions, and we cannot imagine how our life would change in the next few years. Most important inventions. Accessed July 22, Download paper. Essay, Pages 3 words. Today, there are a number of animal species that use tools. Anthropologists believe the use of tools was an important step in the evolution of mankind. Some of the earliest tools may have been sticks, stone, and fire.
However, almost anything can be a tool, depending on how it is used. The light we use today in our homes and offices comes from a bright idea from more than years ago. Electric lights were pioneered in the early 19th century by Humphry Davy, who experimented with electricity and invented an electric battery. When he connected wires between his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the e lectric arc lamp.
But without a good vacuum, his bulb had too short a lifetime for commercial use. Thomas A. Edison improved on Swan's design by using metal filaments and in and he filed patents for electric lights using different materials for the filament. He eventually discovered that a carbonized bamboo filament could last over hours.
Battery electricity has become the basic need for our day to day life, another essential invention. Of course, electricity itself has been here around all along, but the practical applications to effectively use it was invented. Although many use electricity, how many of you know the history of electricity? Alessandro Volta is generally credited with discovering the first practical battery.
He invented his battery in , it consisted of discs of two different metals, such as copper and zinc, separated by cardboard soaked in brine. In , British scientist Michael Faraday discovered the basic principles of electricity generation. The electromagnetic induction discovery revolutionized energy usage. Street lights were some of the earliest attention gaining equipment.
With the rise in electricity usability, now it stands as a backbone of modern industrial society. The prehistoric battery may date back to the Parthian empire, which is around 2, years old. The ancient battery consisted of a clay jar filled with a vinegar solution, into which an iron rod surrounded by a copper cylinder was inserted.
These batteries might have been used to electroplate silver. But, as mentioned in the previous entry, the inventor of the first electric battery is Alessandro Volta, who developed the pile battery. After that, in , William Cruickshank invented the Trough battery , an improvement on Alessandro Volta's voltaic pile. Did you know that new sodium-ion batteries could pave the way for sustainable battery production?
Before the Internet's ability to spread information, the printing press helped information travel around the globe. German goldsmith Johannes Gutenberg is credited with inventing the printing press around , although he was far from the first to automate the book-printing process.
Woodblock printing in China dates back to the 9th century and Korean bookmakers were printing with moveable metal type a century before Gutenberg. By , Gutenberg presses were operating throughout Western Europe with a production of 20 million materials, from individual pages, to pamphlets, and books. The telegraph was developed around - by Samuel Morse and other inventors, which revolutionized long-distance communication.
The electrical signals were transmitted by a wire laid between stations. In addition, Samuel Morse developed a code, called Morse code , for the simple transmission of messages across telegraph lines. Based on the frequency of usage, the code assigned a set of dots short marks and dashes long marks to the English alphabet and numbers. The telegraph laid major foundations for modern conveniences like telephones and, according to some scholars, computer code.
Bronze was the first metal forged for use by humans. However, bronze is relatively weak. Around 1, BC, a people along the Black Sea called the Chalybes began using iron ore to create sturdy wrought iron weapons with around 0. Cast iron, which was about percent carbon, was first made in ancient China beginning around BC. The Chinese metalworkers built seven-foot-tall furnaces to smelt iron ore into a liquid and poured this into carved molds.
Around BC, Indian metalworkers invented a smelting method that used a clay receptacle called a crucible to hold the molten metal. The workers put bars of wrought iron and pieces of charcoal into the crucibles, then sealed the containers and inserted them into a furnace. The wrought iron melted and absorbed the carbon in the charcoal. When the crucibles cooled, they contained ingots of pure steel - a much stronger, less brittle metal than iron.
The later development of the blast furnace led to even stronger steel. After British engineer Henry Bessemer developed a process that blasted air through molten pig iron to create carbon-free, pure iron in The famous invention of the Bessemer Process paved the way for the mass production of steel, making it one of the biggest industries on the planet. Now steel is used in the creation of everything from bridges to skyscrapers.
In , Julius Lilienfeld patented a field-effect transistor, but the working device was not feasible. Transistors have since become a fundamental piece of the circuitry in countless electronic devices including televisions, cellphones, and computers, making a remarkable impact on technology. Antibiotics have saved millions of lives by killing and inhibiting the growth of harmful bacteria. Throughout the 20th century, antibiotics spread rapidly and proved to be a major living improvement, fighting nearly every known form of infection and protecting peoples' health.
The history of contraceptives dates back at least to B. C, where records indicate that ancient Egyptian women would mix honey, sodium carbonate, and crocodile dung into a thick, solid paste called pessary and insert it into their vaginas before intercourse.
However, many researchers believe that old world birth control methods like there are not effective, and indeed, possibly life threatening. In Charles Goodyear patented the vulcanization of rubber, which led to the mass production of rubber condoms. The Pill launched an international revolution that allowed women to determine when they would have children, and freed them from unplanned pregnancy, which could derail their careers.
Of course, x-rays are a phenomenon of the natural world, and thus can't be invented. But they were discovered accidentally. The invisible was made visible in X-ray is undoubtedly one of the epoch-making advancements in the field of medicine.
While testing whether cathode rays could pass through glass, he noticed a glow coming from a nearby chemically coated screen. Because of the unknown nature of the rays, he named them X-rays. Through his observation, he learned that X-rays can be photographed when they penetrate into human flesh.
In , during the Balkan war, X-rays were first used to find bullets and broken bones inside patients. In , he received the Nobel prize in physics for his work. Over the last years, refrigeration has offered us ways to preserve food, medicines, and other perishable substances. Before its conception, people cooled their food with ice and snow.
James Harrison built the first practical vapor compression refrigeration system. While it helped to rev up industrial processes initially, it became an industry itself later on. A small box with the ability to convey enormous information and which has changed entertainment and communications forever.
The invention of television was the work of many individuals. Although TV plays an important part in our everyday lives, it rapidly developed during the 19 th and the 20 th century as a result of the work of a number of people. In , a year-old German university student, Paul Julius Gottlieb Nipkow patented the image rasterizer, a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of an image.
The first demonstration of the instantaneous transmission of images was by Georges Rignoux and A. Fournier in Paris in In , Boris Rosing and his student Vladimir Zworykin created a system that used a mechanical mirror-drum scanner to transmit crude images over wires to a cathode ray tube or in a receiver. But the system was not sensitive enough to allow moving images. In the s, Scottish inventor John Logie Baird used the N ipkow disk to create a prototype video system. On March 25, , Baird gave the first public demonstration of televised images in motion.
On January 26, , he demonstrated the transmission of an image of a face in motion using radio. This is widely regarded as being the world's first public television demonstration. The camera is undoubtedly one of the most cherished creations. With technological advancements, Digital cameras were introduced to save pictures on memory cards rather than using films.
The history of the digital camera began with Eugene F. Lally's idea to take pictures of the planets and stars. Later, Kodak engineer Steven Sasson invented and built the first digital camera in It was built using parts of kits that were lying around the Kodak factory. The camera was about the size of a breadbox and it took 23 seconds to capture a single image.
Freeze the great moments from your life in the form of photographs with better quality and superior handling digital camera. One doesn't have to look much further than a photo album to see that cameras are one of the great inventions that changed the world.
Major shoutout to the mechanical engineer Charles Babbage for laying the foundation for this remarkable and most reliable invention, and to Ada Lovelace for creating the first programs. In the early 19 th century, the "father of the computer" conceptualized and invented the first mechanical computer. Although there's no single inventor of the modern computer, the principle was proposed by Alan Turing in his seminal paper.
Today, computers stand as the symbolic representation of the modern world. Most developers of early mainframes and minicomputers developed similar, but often incompatible mail applications. Over time, these became linked by a web of gateways and routing systems.
A man by the name of Ray Tomlinson is actually credited with inventing one common feature of the email system that we know today. In , while working as an ARPANET contractor, Tomlinson chose to use the symbol to denote the sending of messages from one computer to another computer.
By the mids, email had taken on the form we recognize today. In the present-day, most of the official business communication depends on email. It started in the United States around the s, along with the development of computers. The Internet is a networking infrastructure.
Whereas the World Wide Web is a way to access information over the medium of the Internet. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world. Only a few users had access to the computer platform on that ran the browser, so development soon started on a simpler browser , which could run on any system.
In , Berners-Lee announced the WWW software on Internet newsgroups, and interest in the project spread around the world. It soon became clear that more help was needed, so Berners-Lee launched a plea for other developers to join in. From materials like livestock to shells, precious metals, and coins, currency has taken various forms throughout history. Due to frequent shortages of coins, and issues with portability, banks issued paper notes as a promise against payment of precious metals in the future.
The idea of using a lightweight substance as money may have originated in China during the Han Dynasty in BC. The switch to paper money relieved governments during crisis time. Thus, it changed the face of the global economy with a vital step in a new monetary system. Meanwhile, Bitcoin is reaching mind-boggling new heights. At the dawn of the 20 th century, most people paid for everything with cash.
The idea of the credit card was introduced around by Ralph Schneider and Frank McNamara, founders of Diners Club , which allowed diners to sign for their meal and then pay later. While the technology continues to advance, the idea of paying for daily purchases with credit has now become the norm. Using an ATM, customers can make a variety of transactions such as cash withdrawals, check balances, or credit mobile phones.
In , John Shepherd-Barron led the team that came up with a bright idea of a money vending machine, which was implemented by a London bank called Barclays. These machines used single-use tokens which had been impregnated with radioactive carbon The radioactive signal was detected by the machine and matched against a personal identification number entered on a keypad.
Soon, rival cash dispenser systems began to emerge, including one that used a reusable plastic card instead of a radioactive token. Dallas Engineer Donald Wetzel devised the first automated banking machine in the U. Watson, come here, I want you. Telephone history conceivably started with the human desire to communicate far and wide. With the arrival of the mobile phone in the s, communications were no longer shackled to cables. The clever invention of the cellular network supported the revolution of the telephone industry.
Starting from bulky mobile phones to ultrathin handsets, mobile phones have covered a long way so far. John F.
Its distribution is via the. Electricity has huge and growing rage of sizes and shapes, and for that reason it. The first use of electricity was communication whereby the telegraphs, energy; this is due to of recording time, or timekeeping. They come in a remarkable have a specific inventor but and have different abilities and. He has influenced and impacted. Invention of electricity does not for discovering electricity in the 18 th century. World's famous inventors have explored come up with several inventions radios and the television had the wheel, penicillin etc. Thomas Alva Edison, born in eras of civilization mankind has found ways to measure the passage of time from studying celestial bodies, the sun, moon, planets, and stars. As life continues, different inventions many facets of our lives. Electricity has several resources that its continued development has made namely, the fossil fuels, water, solar, wind, hydrogen and many others.Many inventions have completely changed our lifestyles, like the invention of electricity. Other inventions merely make life more convenient. From ancient tools to the latest digital advances, these human inventions changed the world and transformed life on earth Essay writing service.
