Top 10 Inventions of the World

                     Top 10 Inventions of the World

New top 10 inventions of the world humans are an ingenious species. Though we've been on the planet for a relatively short amount of time (Earth is 4.5 billion years old), modern Homo sapiens have dreamed up and created some amazing, sometimes far-out, things. From the moment someone bashed a rock on the ground to make the first sharp-edged tool, to the debut of the wheel to the development of Mars rovers and the Internet, several key advancements stand out as particularly revolutionary. Here are our top picks for the most important inventions of all time, along with the science behind the invention and how they came about.


1. The Internet

It really needs no introduction: The global system of interconnected computer networks known as the Internet is used by billions of people worldwide. Countless people helped develop it, but the person most often credited with its invention is the computer scientist Lawrence Roberts. In the 1960s, a team of computer scientists working for the U.S. Defense Department's ARPA (Advanced Research Projects Agency) built a communications network to connect the computers in the agency, called ARPANET. It used a method of data transmission called "packet switching" which Roberts, a member of the team, developed based on prior work of other computer  scientists. ARPANET was the predecessor of the Internet.

2. Contraceptives

Not only have birth control pills, condoms and other forms of contraception sparked a sexual revolution in the developed world by allowing men and women to have sex for leisure rather than procreation, they have also drastically reduced the average number of offspring per woman in countries where they are used. With fewer mouths to feed, modern families have achieved higher standards of living and can provide better for each child. Meanwhile, on the global scale, contraceptives are helping the human population gradually level off; our number will probably stabilize by the end of the century. Certain contraceptives, such as condoms, also curb the spread of sexually transmitted diseases.
Natural and herbal contraception has been used for millennia. Condoms came into use in the 18th century, while the earliest oral contraceptive "the pill" was invented in the late 1930s by a chemist named Russell Marker. Scientists are continuing to make advancements in birth control, with some labs even pursuing a male form of "the pill." A permanent birth-control implant called Essure was approved by the Food and Drug Administration in 2002, though in 2016, the FDA warned the implant would need stronger warnings to tell users about serious risks of using Essure.

3. Penicillin

It's one of the most famous discovery stories in history. In 1928, the Scottish scientist Alexander Fleming noticed a bacteria-filled Petri dish in his laboratory with its lid accidentally ajar. The sample had become contaminated with a mold, and everywhere the mold was, the bacteria was dead. That antibiotic mold turned out to be the fungus Penicillium, and over the next two decades, chemists purified it and developed the drug Penicillin, which fights a huge number of bacterial infections in humans without harming the humans themselves.
Penicillin was being mass produced and advertised by 1944. This poster attached to a curbside mailbox advised World War II servicemen to take the drug to rid themselves of venereal disease. About 1 in 10 people have an allergic reaction to the antibiotic, according to study published in 2003 in the journal Clinical Reviews in Allergy and Immunology; even so most of those people go on to be able to tolerate the drug, researchers said.


4. The light bulb

When all you have is natural light, productivity is limited to daylight hours. Light bulbs changed the world by allowing us to be active at night. According to historians, two dozen people were instrumental in inventing incandescent lamps throughout the 1800s; Thomas Edison is credited as the primary inventor because he created a completely functional lighting system, including a generator and wiring as well as a carbon-filament bulb like the one above, in 1879.
As well as initiating the introduction of electricity in homes throughout the Western world, this invention also had a rather unexpected consequence of changing people's sleep patterns. Instead of going to bed at nightfall (having nothing else to do) and sleeping in segments throughout the night separated by periods of wakefulness, we now stay up except for the 7 to 8 hours allotted for sleep, and, ideally, we sleep all in one go.

5. The telephone

Though several inventors did pioneering work on electronic voice transmission (many of whom later filed intellectual property lawsuits when telephone use exploded),

Alexander Graham Bell was the first to be awarded a patent for the electric telephone in 1876. His patent drawing is pictured above.
Though several inventors did pioneering work on electronic voice transmission (many of whom later filed intellectual property lawsuits when telephone use exploded),

Alexander Graham Bell was the first to be awarded a patent for the electric telephone in 1876. (His patent drawing is pictured above.) He drew his inspiration from teaching the deaf and also visits to his hearing-impaired mom, according to PBS. He called the first telephone an "electrical speech machine," according to PBS.The invention quickly took off, and revolutionized global business and communication. When Bell died on Aug. 2, 1922, according to PBS, U.S. telephone service stopped for a minute to honor him.

6. The internal combustion engine

In these engines, the combustion of a fuel releases a high-temperature gas, which, as it expands, applies a force to a piston, moving it. Thus, combustion engines convert chemical energy into mechanical work. Decades of engineering by many scientists went in to designing the internal combustion engine, which took its (essentially) modern form in the latter half of the 19th century. The engine ushered in the Industrial Age, as well as enabling the invention of a huge variety of machines, including modern cars and aircraft.
Pictured are the operating steps of a four-stroke internal combustion engine. The strokes are as follows: 1) Intake stroke - air and vaporised fuel are drawn in. 2)

Compression stroke - fuel vapor and air are compressed and ignited. 3) Power stroke - fuel combusts and piston is pushed downwards, powering the machine. 4) Exhaust
stroke - exhaust is driven out.

7.The printing press

The German Johannes Gutenberg invented the printing press around 1440. Key to its development was the hand mold, a new molding technique that enabled the rapid creation of large quantities of metal movable type. Though others before him — including inventors in China and Korea — had developed movable type made from metal, Gutenberg was the first to create a mechanized process that transferred the ink (which he made from linseed oil and soot) from the movable type to paper.
With this movable type process, printing presses exponentially increased the speed with which book copies could be made, and thus they led to the rapid and widespread dissemination of knowledge for the first time in history. Twenty million volumes had been printed in Western Europe by 1500.

Among other things, the printing press permitted wider access to the Bible, which in turn led to alternative interpretations, including that of Martin Luther, whose "95 Theses" a document printed by the hundred-thousand sparked the Protestant Reformation.

8. The compass

Ancient mariners navigated by the stars, but that method didn't work during the day or on cloudy nights, and so it was unsafe to voyage far from land.
The Chinese invented the first compass sometime between the 9th and 11th century; it was made of lodestone, a naturally-magnetized iron ore, the attractive properties

of which they had been studying for centuries. (Pictured is a model of an ancient Chinese compass from the Han Dynasty; it is a south-indicating ladle, or sinan, made of polished lodestone.) Soon after, the technology passed to Europeans and Arabs through nautical contact. The compass enabled mariners to navigate safely far from land, increasing sea trade and contributing to the Age of Discovery.

9. The nail

Without nails, civilization would surely crumble. This key invention dates back more than 2,000 years to the Ancient Roman period, and became possible only after humans developed the ability to cast and shape metal. Previously, wood structures had to be built by interlocking adjacent boards geometrically a much more arduous construction process.

Until the 1790s and early 1800s, hand-wrought nails were the norm, with a blacksmith heating a square iron rod and then hammering it on four sides to create a point, according to the University of Vermont. Nail-making machines came online between the 1790s and the early 1800s. Technology for crafting nails continued to advance; After Henry Bessemer developed a process to mass-produce steel from iron, the iron nails of yesteryear slowly waned and by 1886, 10 percent of U.S. nails were created from soft steel wire, according to the University of Vermont. By 1913, 90 percent of nails produced in the U.S. were steel wire. Meanwhile, the screw a stronger but harder-to-insert fastener is thought to have been invented by the Greek scholar Archimedes in the third century B.C.


10. The wheel

Before the invention of the wheel in 3500 B.C., humans were severely limited in how much stuff we could transport over land, and how far. Apparently the wheel itself  wasn't the most difficult part of "inventing the wheel." When it came time to connect a non-moving platform to that rolling cylinder, things got tricky, according to David Anthony, a professor of anthropology at Hartwick College.

"The stroke of brilliance was the wheel-and-axle concept," Anthony previously told Live Science. "But then making it was also difficult." For instance, the holes at the center of the wheels and the ends of the fixed axles had to be nearly perfectly round and smooth, he said. The size of the axle was also a critical factor, as was its snugness inside the hole (not too tight, but not too loose, either). The hard work paid off, big time. Wheeled carts facilitated agriculture and commerce by enabling the transportation of goods to and from markets, as well as easing the burdens of people traveling great distances. Now, wheels are vital to our way of life, found in everything from clocks to vehicles to turbines.

New NASA Program with Supersonic Jet

                   New NASA Program with Supersonic Jet

A new passenger jet that can fly at supersonic speeds without the distinctive but earsplitting sonic "boom" generated when these superfast planes travel faster than the speed of sound is one step closer to getting in the air. NASA has awarded a contract to Lockheed Martin Aeronautics to come up with a preliminary design for the supersonic jet. The company will receive $20 million over 17 months to come up with a preliminary design, according to NASA. The Lockheed team includes individuals from GE Aviation and Tri Models Inc., acting as subcontractors, the agency said.

NASA envisions a "low boom" aircraft that emits a supersonic "heartbeat," or a soft thump, rather than startlingly noisy sonic booms, when it breaks the sound barrier. At the end of its contract, Lockheed will be expected to outline the proposed jet's baseline requirements and design in order to meet NASA's expectations for the agency's Quiet Supersonic Technology (QueSST) program. 

After a demonstration version of the jet is built, the vehicle will undergo analytical and wind-tunnel tests, according to NASA. "Developing, building and flight testing a quiet supersonic X-plane is the next logical step in our path to enabling the industry's decision to open supersonic travel for the flying public," Jaiwon Shin, associate administrator for NASA's Aeronautics Research Mission Directorate, said in a statement.

Once the jet is ready for flight tests, NASA will conduct low-boom flight demonstrations to gauge the public's response to quieter supersonic planes. The actual design and construction of the QueSST jet will be awarded under a future contract, NASA officials said. The loud booms generated by supersonic aircraft prompted the U.S. Federal Aviation Administration to ban overland flights by these aircraft in 1973. NASA, however, said in a previous statement that it is working with the FAA to change those regulations. 

"We are working with other agencies across the world to support development of new noise certification for supersonic flight, so instead of being prohibited, it would be allowed over land and sea," Alexandra Loubeau, an acoustics engineer at NASA's Langley Research Center in Hampton, Virginia, said in a statement released in late 2015.

The QueSST jet is the first in a series of X-planes that will receive funding in NASA's fiscal 2017 budget, as a part of the agency's New Aviation Horizons initiative. The initiative aims to make future aircraft safer, "greener" and more efficient, using metrics such as fuel use, emissions and noise to judge their performance. The first flights under NASA's New Aviation Horizons initiative are expected to begin around 2020, depending on funding, the agency said.

Solid State Drive Data Storage

                      Solid State Drive Data Storage

A solid-state drive (SSD) is a type of computer storage. SSDs work just like a normal hard drive, only much faster. They allow your computer to boot in seconds, and  complicated software will load and run much
faster. SSDs have no moving parts, so they're more reliable too, although they aren't available in the same large capacities as some normal hard drives.

Reliability

As they've got no moving parts, SSDs are more reliable than regular hard drives. They can withstand more extreme temperatures, stand up to shocks and suffer less wear and tear. They're also compact and lightweight, so laptops featuring SSDs are usually thinner and lighter.

Laptop with a solid state drive View all SSD laptops
Speed and wake-up time

SSDs run much faster than regular hard drives. Computers with SSDs are more responsive and work faster than those without. A computer with an SSD can boot in as little as three seconds, so you can get to work much quicker. An SSD is the ideal storage device for a high-performance PC, and helps run photo editing, music production and graphic design software at their best.

Battery life

A laptop with a SSD uses significantly less power than one with a regular hard drive. This is because there are no moving parts in an SSD to power, so you get a longer

battery life along with increased performance. They generate less heat too, so you can work with a laptop on your knee in comfort for longer.
