The Greatest Invention

Inventions simplify and improve our life. In my opinion, a strong start to innovation began in the 20th century. An incredible amount was invented for both general use and scientific things. Now we can`t imagine our life without electricity, satellite communications, iron, hot water in the shower, telephone.

I believe that the greatest invention was the Internet. This difficult system not only simplified our life, it completely changed it. Changed our thinking, lifestyle, work and study.

Using the Internet we can find out any information in seconds, find out any recipe for a dish from anywhere in the world. Learn from the comfort of home. Work at a different pace. But most importantly, we can be in touch with our loved ones 24 hours a day. We can make video calls, write messages, call, and send photos. This network came over the whole world, every person. Undoubtedly, our life has changed with this invention. It became possible to read any book, check-in for a plane flight, apply to government agencies and much more.

But there is always a second side. In addition to all the benefits, with the advent of the Internet, bad things have come. For example, due to private sitting without movement, the health of many people has deteriorated. Haters appeared on the network who behave badly towards other users. In addition to the necessary and useful information, one can easily find false information. You can stumble upon the agitation of terrorists.

But in my opinion, all the bad aspects of the Internet can also be found in everyday life. You should just beware of unfamiliar sites on the Internet and unfamiliar places in real life.

8 Inventions of 20th Century that Changed the World

Humankind has had some impressive engineering moments in the 20th century. Now don’t get us wrong, the 21st century has produced some amazing inventions that you are probably using throughout your household and to read this article.

Yet these same modern day inventions garnered their foundations in the 20th century.

In fact, most would argue that the past century is one of the most remarkable in human history producing a host of technological advances, gadgets, and scientific discoveries.

From the vacuum cleaner to the nuclear bomb these feats of engineering have laid the framework for the modern era and will continue to do so for years to come.

So as you probably garnered from the title, today we are going to explore some of the 20th century’s best inventions, things that have both shaped the world and your everyday life, so let’s begin.

The Airplane

Let’s start with something a little more obvious, the airplane. Think about how much smaller the world became once commercial flights were possible. However, let’s go back a step further.

Invented in 1903 by Wilbur and Orville Wright, the brothers brought to life a concept that was reserved for mythological stories.

However, the airplane was not taken seriously until Charles Lindberg made his solo flight across the Atlantic Ocean.

It revolutionized countless industries beyond just the realms of transportation. The effects of the airplane can be felt in satellite and communication, business and commerce just to name a few.

Just think of a life without the option of flying away to somewhere new.

The Television

Though your grandparents may disagree, television changed the world for the better.

Created in 1926 by John Logie Baird, the television was one of the first inventions to affect the lives of masses all over the world, and to this day still remains the most popular ways of getting information.

Broadcasting both news and entertainment, the television created entirely new industries impacting culture to such an extent that it influenced the way people think about important social issues such as race, gender, and class.

The Computer

Imagine a life without your smartphone or laptop. Yes, of course, it is possible, but the loss would be dramatically felt. On a much larger scale, some of the greatest scientific discoveries and inventions in recent years can be contributed to the computer.

The computer itself was born out of the minds of the many scientists, researchers, and mathematicians, with the first programmable computer, the Z1, being created between 1936-1938.

From getting man to the moon to changing the way people communicate, the computer has help mankind create a host of technologies that still play an integral role in our daily lives.

The Radio

Occasionally underappreciated, the radio was one of the first major inventions of the 20th century. Invented in conjunction with many different scientists including Nikola Tesla and Guglielmo Marconi, the radio became the most used forms of communications in the world.

The radio in the early 20th century served as a social bonding tool, a place of news, and education tool, and for emergency broadcasts, in short, providing an entirely new way for people to communicate and interact.

Nuclear Power

Utilizing the energy released by splitting the atoms of certain elements, the harnessing of nuclear power would go on to change the world in more ways than one. First developed in the 1940s as a means to produce bombs, it was not until the 1950s that the research of nuclear energy turned peaceful.

Today nuclear energy provides, about 11% of the world’s electricity from about 450 power reactors making it the world’s second-largest source of low-carbon power. Right now, 50 countries use nuclear energy research industries ranging from the medical field to the industrial field.

The Automobile

The automobile was under development in Europe in the 19th century, however, the vehicle did not come into fruition until the early 20th century. Once it did arrive, no more horse and buggies.

Popularized by Henry Ford’s Model T in 1908, the automobile gave the average person a bigger degree of mobility and personal freedom while also spawning a revolution in the market place.

Goods could now be transported much more easily as well quickly, the seeds of the traveling industry were planted, people could move out of the city and live in the suburbs, all of this thanks to the automobile.

What Are the Most Important Inventions of the 20th Century

There can be no doubt that the twentieth century is one of the most remarkable in human history for its previously unparalleled rate of technological advances and scientific discoveries, a rate that continues to this day. In fact, there were so many new gadgets invented and discoveries made in the last century that it’s difficult to pare the list down to just the ten (which is why there will be a number of glaring omissions from my list). However, I think I have managed to whittle it down to those ten innovations or technologies that have had the greatest influence on humanity—both positively and the negatively. And so, without further ado and in no particular order, here are my nominees for the Most Important Inventions of the 20th Century of the twentieth century.

10. Nuclear Power

Nuclear power was to the twentieth century what steam power had been to the nineteenth: a game changer. Suddenly humanity had a power source that didn’t pollute, was efficient and practically unlimited, and so had the potential to change the planet overnight. Unfortunately, it was a two-edged sword in that this same energy source could be used to create the most destructive weapons in history, threatening human survival with its very presence. Additionally, while nuclear power plants didn’t spew pollutants into the air, in the hands of the truly incompetent they had the capacity to render whole regions radioactive and, as such, uninhabitable for generations (as was demonstrated at Chernobyl in 1986).

However, it is hard to deny the overall positive impact nuclear power has had. The fear of mutually assured destruction probably prevented the world from experiencing a third world war and, when operated safely, nuclear power plants truly are a superb and cost-efficient energy source that has the capacity to power entire cities. The only question is whether we’re mature enough to handle that power into the next century.

9. The Personal Computer

It’s difficult to imagine our world today without computers. Of course, they have been around since World War Two, but they were clunky, massively expensive things that had all the calculating power of a brick. When Steve Wozniak and Stephen Jobs introduced the Apple in 1976, however, it changed everything and the rest is, as they say, history. Today, of course, they are everywhere and we have become so dependent upon them that many people almost feel naked without one. For some, they even provide the very means of maintaining a livelihood: we use them to keep track of our finances, write books, design logos and sell real estate. Plus, they are rapidly replacing the stereo and television in their ability to entertain us with music, movies, and games. Makes it hard to understand how our ancestors did so well without them, doesn’t it? (Image: the Apple 1, 1976.)

8. The Airplane

Just as the locomotive made the world a smaller place in the nineteenth century, the airplane did the same for us in the twentieth century, shrinking our planet to the point that a person could fly anywhere in the world in a matter of hours. Not only have they made travel quick and safe, but aircraft provide many other services as well: from crop dusting and fighting forest fires to overnight delivery of packages and chasing hurricanes. They have also revolutionized warfare, turning battle into a long-range affair fought at arm’s length by machines of such sophistication that the way wars are fought has completely changed. Of course, they’ve also been responsible for leveling whole cities and bringing war to the civilian population—who had rarely been directly affected by war until the twentieth century—but then no invention is perfect.

7. The Automobile

Though under development in Europe during the nineteenth century, the automobile didn’t really become a practical and reliable source of transportation until the twentieth century. Once it did, it changed everything; overnight the horse and buggy became quaint anachronisms while much of the country was paved over to make room for endless ribbons of asphalt. It also brought about a revolution in the market place, suddenly making it possible to truck in goods that otherwise would be impossible to acquire. Most of all, Henry Ford’s assembly-line production style made the automobile affordable and accessible to the average person (before Ford’s Model T was introduced in 1908, only the fabulously wealthy could afford a car). The automobile gave everyone a degree of mobility and personal freedom our forefathers could only dream of, and turned entire generations of teenagers into raging revheads.

6. Rocketry

While the rocket was first invented and used by the Chinese over three thousand years ago—and used occasionally by the Greeks and Romans since —it wasn’t until the twentieth century that it came into its own and became more than just a dazzling amusement or a largely harmless but still effective “terror weapon” for ancient armies. In the twentieth century, rockets became bigger and more powerful. Most importantly, they became controllable, which suddenly made them useful both as weapons of war and, even more vitally, as our means of accessing outer space.

Without the rocket, it is safe to say we would not only have never gone to the moon or visited every planet in our solar system. Rockets also place satellites into orbit around our planet, so without them we also wouldn’t be able to use GPS, predict the weather, make international calls or, for the most part, even use our cell phones much of the time.

5. The Submarine

Though submersible vessels had been used in the past (the CSS Hunley during the Civil War) and the first true submarine was invented in the 1880’s, it wasn’t until the twentieth century that the modern submarine came into its own. What started as an irritating, but still deadly, weapon in World War One grew into a monstrosity in World War Two- sinking more than any other type of weapon used.

Today, with the advent of nuclear power—which gave the submarine nearly unlimited range and endurance—it has become the capital warship in every first-class Navy in the world and as such has effectively rendered naval warfare of the past obsolete. How effective is the modern submarine? Ask anyone who has ever served on one. They’ll tell you there’s only two types of ships in the world: submarines and targets. ‘Nuff said.

4. Antibiotics

Until Alexander Fleming discovered penicillin in 1928, almost any little bug that someone picked up was potentially fatal. Once penicillin—and later a whole range of other antibiotics—came on the scene, however, death due to bacterial infection became rare, resulting in a greatly reduced mortality rate and much longer life-span. It also rendered many scourges of the past—from small pox and typhoid to gonorrhea and syphilis—obsolete or, at least in the case of venereal disease, something easily treatable.

3. Television

Yes, I know it destroys brain cells and renders people emotionally and psychologically damaged, but really, where would we be without the boob tube? It is society’s baby-sitter, news source, teacher, entertainer, and story-teller. When in competent hands, television can even be useful at times.

Mostly, though, it fills our days with vapidity and all manner of inane and obnoxious commercials, and is the single greatest reason that families no longer eat in the kitchen or dining room anymore, but instead huddle in the living room around their television eating microwavable food and spilling soft drinks on the sofa. Still, even while we pretend we hate it, we can’t help but seeing what’s on tonight. Worse, most of us would have no idea what to do with our time without it, which is probably the saddest commentary of all.

2. The Internet

The computer rendered the typewriter obsolete and made writing in long-hand a thing of the past, but it took the internet to truly turn the computer into the monster it is today. While the airplane shrank our planet to the point that one could fly from New York to London in six hours, the internet made it possible to be there in a few seconds. It allows truth to make it into and out of repressive countries, it foments revolutions, and spreads lies at the speed of light. It also gives anyone the ability to buy and sell almost anything imaginable, find and torment old school mates, watch the latest you-tube videos, and even find their perfect life partner, all for a few bucks a month. Oh, and you can also get useful information off it if you don’t mind scrolling through 15,000 hits to find out just how long snails really live. Where would we be without it?

1. Radio

Few people today can appreciate the impact the advent of radio had on the twentieth century. Not only did it suddenly make it possible for a person to be heard from hundreds or even thousands of miles away without the use of a wire (quite an accomplishment in the first years of the century) but it was the center of family life through the end of the Second World War and into the doldrums of the fifties, when it was gradually replaced by that new-fangled contraption, the television.

Today, it seems to only be useful in the car as a means of keeping the driver from falling asleep behind the wheel or as a tool of talk radio designed to rile the masses. In its day, however, it was every bit as vital to existence as the television, the computer, the microwave, and the cell phone are to us today.

Uh hello? The AIR CONDITIONER!

what unuseful stuff. the radio at first

radio is important invention I think it is best investment who invented by a gr scientist

Air conditioning unit?

The transistor is by far the most important invention of the 20th century, maybe even of the second millenium with Guttenbergs printing press a close competitor.

Air Conditioning System.

If they not invented yet, there will be no High-raise Buildings and Seafood in this world

This is very useful information thanks

Actually a submarine was used in the Revolutionary war by the Colonies and the Civil War by both sides.

Auto mobile should be first because it gets us to walmart quiker if u know what im saying

?Atypical InFlow Thermodynamic?Technology Proposal Submission?Novel Fueled Motor Engine Type

??YouTube; * Atypical New • GEARTURBINE / Retrodynamic = DextroRPM VS LevoInFlow + Ying Yang Thrust Way Type – Non Waste Looses

-This innovative concept consists of hull and core where are held all 8 bteps of the work-flow which make the concept functional. The core has several gears and turbines which are responsible for these 8 steps (5 of them are dedicated to the turbo stages). The first step is fuel compression, followed by 2 cold turbo levels. The fourth step is where the fuel starts burning – combustion stage, which creates thrust for the next, 5th step – thrust step, which provides power to the planetary gears and turbines and moves the system. This step is followed by two hot turbo steps and the circle is enclosed by the final 8th step – bigger turbine. All this motion in a retrodynamic circumstance effect, wich is plus higher RPM speed by self motion. The Reaction at front of the action.

*8-X/Y Thermodynamic CYCLE – Way Steps:?1)1-Compression / bigger?2)2-Turbo 1 cold?3)2-Turbo 2 cold?4)2-Combustion – circular motion flames / opposites?5)2-Thrust – single turbo & planetary gears / ying yang?6)2-Turbo 2 hot?7)2-Turbo 1 hot?8)1-Turbine / bigger

-With Retrodynamic Dextrogiro vs Levogiro Phenomenon Effect. / Rotor-RPM VS InFlow / front to front; “Collision-Interaction Type” – inflow vs blades-gear-move. Technical unique dynamic innovative motion mode. [Retrodynamic Reaction = When the inflow have more velocity the rotor have more RPM Acceleration, with high (XY Position) Momentum] Which the internal flow (and rotor) duplicate its speed, when activated being in a rotor (and inflow) with [inverse] opposite Turns. The Reaction at front of the action. A very strong Novel torque power concept.

-Non waste parasitic looses for; friction, cooling, lubrication & combustion.

·2-Imploturbocompressor; One Moving Part System Excellence Design – The InFlow Interaction comes from Macro-Flow and goes to Micro-Flow by Implossion – Only One Compression Step; Inflow, Compression and outflow at one simple circular dynamic motion Concept.

*·“Excellence in Design” because is only one moving part. Only one unique compression step. Inflow and out flow at the same one system, This invention by its nature a logic and simple conception in the dynamics flow mechanics area. The invention is a wing made of one piece in a rotating motion, contained in a pair cavity system connected by implocavity, and interacting dynamically with a flow, that passes internally “Imploded” through its simple mechanism. This flow can be gas (air) or liquid (water). And have two diferents aplications, in two diferents form-function; this one can be received (using the dynamic flow passage, as a receiver). Or it can be generated (with a power plant, generating a propulsion).

Presenting one of the many diferents examples, could specifically be this same invention applied in pair in every bar end, similar to what would be a turbine reaction or turbocompressor, and making the best profit of a exhaust gas dynamic flow, compressing a new air entrance and therefore falling into the technical field of the reaction turbines. This of course, considerating materials that are resistant to the high temperatures such as the ceramics ones. And furthermore this invention approaches more the combustion point and therefore also more to the gases expansion point, in order to search a higher expanding dynamic strength. It could, for example, be presented into an inter dynamic rotor system (aplication), supported internally and in a rotating system. And likewise being able to activate a new concept of dynamic turbine by pushing gearing, and likewise, creating a new technical field. Or can be in a more simple way by means of the system of this same invention applied to the bar end, but without a movement of interaction with the rotor, only the rotary dynamics in a static point for any type of mechanical work such as a dynamo in order to generate electricity through the dynamic strength of a flow when it is rotating at the moment it receives it, just like a pelton well do.

And when the flow that is received and that is intended to be used at best, must no necessarily by a exhausting or rejection gas, but must be a dynamic passing gas or liquid flow with the only intention to count it or to measure it. This could be possible at the passing and interacting period when it passes inside its simple mechanism. This can be in any point of the flow trajectory.

In case the flow that is received is a water falling by gravity, and a dynamo is placed on the rotary bar, the Imploturbocompressor can profit an be obtained by generating? electricity such as obtained by the pelton well, like I say before.

Or only receive the liquid flow, in order to measure its passage with a counter placed on the bar, because when this flow passes through the simple mechanism of a rotating wing made of only one piece it interacts within the implocavities system. And this flow can be air wind, with the diference of can have an horizontal position, and have wind from all the sides and all the time. The aforementioned information about this invention refers to technical applications, such as a dynamic flow receiver. (whether being gas or liquid).

Connecting the free end of the bar of this invention to a power plant (manual, electrical, mechanical, or combusting, etc…), there will be available a capacity and a position in order to generate the flow dynamics (or even better, a propulsion). This applied? to gas flows (air) or to liquid flow (water). This of course, considering the due rotating directions as well as the inclination, wings, curvature and the due dimensioning for every application of every technical field.

With the appropriate power plant and the appropriate dimensioning and number of RPM this invention is also feasible to generate an atmospheric air propulsion and the autoprolpusion of an aircraft. Being an effective and very simple system that implodes and compresses the atmospheric air permits the creation of a new concept of propulsion for aircrafts, due to its simple mechanism and innovative nature. At the place of the aircraft were the system appears and the manner how the propulsion direction can be oriented with a vectorial flow (no lobster tail) with I call “yo-yo system” (middle cut (at the shell) to move, one side loose), guided and balanced is feasible to create a new concept of TOVL-vertical take-off landing, I wish good for a wild conditions. Because the exhaust propulsion can going out radial in all the 360 vectorial positions, going out direct all the time in all the vectors direction. With his rotor cover for an better furtive fly, like going down of a bridge for example.

The “Imploturbocompressor”, is a good option to pump water, or a gas flow, and all kinds of pipes lines dynamic moves.

Likewise, with the due form and dimensioning, and considering the liquid density and the due revolutions for this element there could be generated a propulsion (water) in order to move an aquatic ship, whether on surface or under water. Also can be a good option to pump liquid combustion for a rocket propulsion.

Making a metaphoric comparison with the intention to expose it more clearly for a better comprehension of this innovative technical detail, it would be similar to the trajectory and motion of a dynamic flow compared with a rope (extended) that passes through the system would have now a knot (without obstructing the flow), so the complete way of the flow at the imploturbocompresor system have three direct ways and bettween make two diferents turns; direct way (entrance) – turn – direct way (implocavity) – turn – direct way (exit), all this in a circular move system.

Its prudent to mention that the curves and the inclinations of the blades of a rotating wing made of this invention, is conferred by its shape and function a structural rigidity allowing it to conduct and alter appropriately the dynamic flow passing through its system.

This invention are very versatile, can be applied and used for any kind of flow, whether as gas or as a liquid, received or be generating it.? And it has different technical fields, being applied in any circumstance where the intention is to obtain an profitable work, to modify on his imploflow system.

23 Greatest Inventions of the 20th Century

The 20th century is, undoubtedly, the century that changed the world entirely. Now, this has had both, positive and negative, impacts. But, for the most part, the lives of humans have vastly improved.

Although there have been hundreds of remarkable inventions, this list has only covered 23. These include some of the most used items along with a few miraculous inventions that no one had ever even imagined of.

Greatest Inventions of the 20th Century
(Video)

Hold tight as this is going to be a venturesome ride through the 20th century!

1. Airplanes

In the 20th century, humankind touched the sky, literally. The credit is given to the Wright brothers who made the first flying airplane in 1903. Now, this is a confusing topic in other parts of the world, such as Brazi. The reason behind this is that even though the Wright brothers initially invented the airplane, a lot of other scientists from other parts of the world contributed to the improvement of the aviation industry. One such example is Alberto Santos-Dumont who was a Brazilian expert. He was the first to build a heavier-than-air aircraft in the European countries, although this was an unsuccessful invention.

As for the works of the Wright brothers, they did lay roots of the craft that has made it a piece of cake to travel to the other side of the world. The mere invention of airplanes contributed to the increased rates of trade, tourism, and lots of other good things. You may also blame this invention for wars and chaos, but overall, it won’t be wrong to say that the entire future of this world has been altered with this miraculous creation.

2. Personal Computer

Computers were not something that only one scientist was working on. There were many experts who were putting in efforts to create a successful final product around the same time. However, the first-ever computer that was programmable and worked effectively is said to be the Z1. This computer came into existence between 1936 and 1938. But, the works in this industry didn’t stop.

Alan Turning is regarded as the person who introduced the concept of a personal computer. He suggested that a machine should be invented that would be able to solve any problem as long as the problem was entered in the form of certain instructions. Alongside this, Konrad Zuse was working on creating similar machines. He is the one who made the Z3 computer. Other than that, the US Army sponsored the creation of Eniac. This was an all-electronic computer, run by a program, but without any storage space. After WW2, the US Army made this machine public. This is when Manchester University introduced an improved prototype that could store programs. You may consider this prototype the closest to today’s computers. However, the improvements did not stop and continue to this day.

3. Radio

You may think that radios are not as useful. But, the truth is, radio waves are used continually, all around you. The transmission of your mobile’s signals is also a form of radio waves. Keeping this in mind, it is clear that radio is a vital part of today’s world. Yet, it is unclear who really invented the radio.

The name most commonly associated with the invention of the radio is Marconi. He was the first to have sent a transatlantic radio message. This happened in 1901. However, before Marconi cashed it, Tesla had already introduced the idea of a radio. Moreover, the idea of wireless communication was not new at this point. Back in the 1800s, scientists were working on the concepts of electromagnetic waves. This led to the discovery of what we know as radio waves now. This long-wavelength light was discovered a long time ago, but yes, the practical implementation did not happen until the 20th century. Now, we don’t know which one point to name the real inventor. But we do know that this invention had been in the works for long and has surely been a life-changing addition to this world.

4. Television

Can you imagine your life without television? No entertainment, news updates, movies or background music through your chores. How boring would that be? Luckily, that is just a thought because back in 1927, Philo Taylor Farnsworth invented the first TV. Before this, a few people had come up with mechanical TV systems but they were a fail. This invention was the first electronic television that could also capture moving images. Although, this device was very different from what we know TV as of today.

The works of this 21-year old have helped educate the world beyond imagination. Word spreads from one side of the world to the other within seconds through TV transmissions. It has been a source of information in times of urgency. The whole broadcast media industry has flourished based on this invention alongside the radio. Moreover, it is a part of every household which is enough to explain its importance in this age.

5. Nuclear Power

It all started in the 1940s when some genius minds started working on the idea of nuclear power. The world awaited brilliant inventions that could possibly make the world an easier place to live in. Nuclear energy operated cars, free power generation, and other similar ideas started emerging. Everything was going great until the practical aspect of the work began. There was a lack of funds since sponsors had a hard time trusting this new, unknown idea. They much rather prefer the good old coal, oil, and gas instead of a risky investment. However, with the war in middle-east during the 1970s, the oil prices boosted immensely.

Within the next decade, people started showing way more interest in the idea and nuclear reactors started emerging all across the world. There is most definitely the risk of destruction. Radioactive emissions can make an area unsuitable for living things. However, the long list of pros of nuclear power cannot be ignored either.

6. Antibiotics

Considering the high rate of illnesses, it won’t be wrong to say that antibiotics have saved humankind. Had it not been for these bacteria fighters, the death rate would be way higher. The history behind antibiotics is pretty interesting. The discovery of this life-changing substance was more of an accident than an invention. Alexander Fleming, in 1928, first noticed the presence of a ‘mold’ that was killing the bacteria that he was studying. This was researched further and in 1941, Howard Florey and Ernst Chain presented this substance as a medicine named Penicillin.

Penicillin was only named as antibiotic 30 years later. Antibiotics played a huge role in not just saving human lives, but also in increasing the production of meat and milk. It came with the side effect of killing good bacteria along with the bad ones. Now, this exposed everyone who consumes meat or dairy to the risk of a lower resistance against diseases even if they have never consumed antibiotics themselves. The governments of many countries have banned the use of antibiotics in farms today which has lowered this risk while maintaining the positive effects of antibiotics.

7. Cell Phones

You’re probably reading this article on a smartphone right now. Although smartphones did not come into the picture until the end of the 20th century and beginning of the 21st century, the roots were laid down with the invention of the first cell phone. You probably have a very different image in your mind than what the first cell phone actually looked like. It did not have a touch-screen, internet or tens of entertainment options. All that this device could do was make phone calls. The cell phone had an antenna, actual buttons to dial the number, and a small display to show notifications. Unlike today’s compact and smart designs, this cell phone was huge, bulky, and not pretty at all.

As for the brains behind this invention, the credit is given to the company Motorola. Like most creations, the cell phone was only in the works simultaneously in multiple companies. However, Motorola was the one who made the first successful phone call from their invention. Ironically, Martin Cooper, an executive at Motorola, made this first legendary phone call to a rival company to inform them of their success. This was on April 3, 1973. Ever since then, the device has improved and to this day, the updates haven’t stopped.

8. Rocketry

One thing this world is very proud of is that humans have been able to reach the moon. Without the invention of rockets, this would never have been possible. Not only that, but rockets are also to be credited for a lot of other things we use on a daily basis. The only reason we have access to GPS is that rockets put satellites in space. Moreover, the majority of what our cell phones offer is all because of rockets.

Although rockets have been around in China since the 10th century, the true use of rockets only began in the 20th century. The earlier rockets were mere weapons of war, used to shoot arrows. However, after the 20th century, they became much bigger and stronger. Newton’s cradle and the second law of motion were just some of the theories used by scientists to explain that reaching the moon was possible. But, the first one to ever implement these was Robert Goddard who built the first liquid propelled rocket in 1926. Though, his rocket’s first flight was only up to a height of 12.5 meters.

9. Automobiles

The 20th century really did make commute possible. A world without automobiles may have been less polluted, but would be as advanced as it is today? From the everyday ease of traveling to the boom in trade, automobiles have helped this world move forward, literally. The first automobile invented was the motor car designed by Carl Benz in1879. This car ran on a gasoline-powered engine. However, the automobile that made this invention more accessible and user-friendly only came into existence in the 20th century.

Henry Ford is the man who made Model T in 1908. This car was affordable for an average middle-class American. Although the brains behind this invention were someone else’s, it was only due to Henry Ford that this industry flourished. Hence, Henry Ford is the man associated with the boom of automobiles. His company was able to sell millions of automobiles and to this day, Ford is a world-famous and successful business.

10. Submarine

Who knew that one day, humans will be able to survive underwater? Like many other 20th century inventions, the submarine has also been in the works long before it was officially announced. The use of submarine vessels in the Civil War back in the 1880s is proof that the idea was not new. But, the base of the modern submarines was nothing like the submarines of this time.

Submarines got a glow-up in the 20th century. They became an important weapon during the WW2. Today, the submarine paired with nuclear power is more powerful than one can imagine. The submarines used by the navy forces worldwide have an unlimited shooting range. Other than their use during wars, submarines also play a huge role in scientific research.

11. Internet

I can confidently say that the internet is ultimately the most important invention of all times and I’m sure you’ll agree. This ‘network of networks’ was initially assembled in 1983 by Robert E. Kahn and Vint Cerf. But, it became more accessible in the 1990s after the ‘world wide web’ was created.

The internet shrunk the world to the size of whatever device you own. Yes, airplanes and automobiles brought places closer, but the internet literally put them in your palm. Today, the entire world is dependent on this invention. From business to economy to politics to entertainment, you name it and it is somehow connected to the internet in one way or another. People from all across the world can connect with just one click. It has promoted the development of this world, in general. A huge money-making industry has flourished on the roots of the internet. This genius invention shook the world to its core like nothing else ever has!

12. Xerography

Xerography, or electrophotography, came into existence in 1938. All the ‘xerox’ copies you are able to make are because of the works of Chester Carlson. He was mostly inspired by the publications of Pal Selenyi, as I’m sure many more were too. However, Chester Carlson was the one to receive the patent for this invention.

Now, xerography has played a huge role in offices as well as in educational institutes. Like most American shows depict, xerography has also served as an easy excuse to meet up with your office fling in the xerox room. All jokes aside, the invention of xerography reduced handwork immensely. Prior to the availability of a photocopying device, people had to make exact copies of the printed documents by hand in order to reduce the printing expenditure. Xerox machines are also used for the printing of books and magazines in bulk. Although xerography was only available in grayscale at first, with time it was developed enough to produce colored prints too.

13. Vacuums

Have you ever noticed the amount of dust that gathers in your home when you don’t vacuum it for a few days? Now imagine how worse it would’ve been if there were no vacuum cleaners at all. Manually cleaning surfaces is way harder and time-consuming too. Fortunately, Hubert Cecil Booth and David T. Kenney created the masterpiece that we call a vacuum cleaner in 1901.

The general idea on which this machine operated was pretty similar to the vacuum cleaners we use today. However, famous names such as Kirby and Hoover continued to improve this machine. Daniel Hess was the man who came up with the idea of a vacuum that could be used on carpets. The bottom line is that over time vacuums have become more and more efficient.

14. Robots

A lot of people are afraid that someday robots will be smarter than humans and take over the world. Then there is also the hassle of filling out security checks on websites to confirm that you’re not a robot. These and all other robot-related issues cannot be blamed on one person since robots have been in the making for centuries. It all started with simple automated devices that eventually turned into human look-alikes that can talk, feel, and understand.

A modern robot with complex behavior was made by William Grey Walter in 1949. His robot had more similarities with a human, mainly because that is what his aim was. He wired up this robot to portray how brain cells work. Later, George Devol created the first programmable digital robot in 1954. This was called the Unimate and is credited for laying roots of the modern robotics industry.

15. Microwave Oven

The machine that heats up your pizza, pops your corn kernels and warms your hot chocolate was born in the 20th century too. The well-loved, well-used device in every kitchen, the microwave oven, was invented by Percy Spencer after the WW2. It was called a Radarange instead of a microwave oven back then. The first Radarange was sold in 1946.

You may not believe this but this invention only happened due to candy. Spencer was an American engineer. He noticed that some sort of waves on the radar that he was working on were cooking the candy in his pocket. Of course, he experimented here and there to finally find out that if microwaves were concentrated on food, the food will heat up and cook.

Here’s a fun fact:

To test his invention, the first thing he cooked in his microwave oven was popcorn!

16. Tea Bags

If you’re a tea lover, it might be hard for you to imagine a time when there were no tea bags. Yes, tea leaves didn’t always come in a permeable paper that you could dip into warm water. Before this time, and in some places even today, tea leaves are cooked in boiling water on flames. However, some tea enthusiasts who craved tea on the go came up with the brilliant idea of tea bags.

We don’t know who the mastermind behind this invention is. But, we do know who the first importer was. It was Thomas Sullivan who shipped tea bags all around the world. The sacks full of tea leaves were around since 1904. However, the rectangular tea bags we see today came into existence in 1944.

17. Safety Razor

Before the 20th century, people used a sharp metal blade to shave. Since there was no safety shield around it, it was a very tricky and dangerous tool to use. Luckily, King Camp Gilette, along with William Emery Nickerson, came up with a disposable razor in 1901. This invention was a huge success from the get-go due to its feasibility and safe use. These disposable safety razors were sold under the company name of the American Safety Razor Company. In 1904, the company was renamed to the Gilette Safety Razor Company. King Camp Gilette quickly became a millionaire. Who would have guessed that safety razors were the beginning of this world-famous company?

18. Compact Disc

Compact discs came in the 20th century and pretty much disappeared by the 21st. Although there isn’t much use of CDs in this day and age, they were once in a phase of a boom. It all started with James Russell’s love for music. Vinyl records just wouldn’t satisfy him. They had a low sound quality and would also damage easily. He started by replacing the needle on the record player with different items. However, none of them worked. That is when it hit him, what if the record player read the disc without touching it?

In 1965, Russell introduced his idea of digitized music to the Battelle Memorial Institue. After some hesitation, Russell got the heads up to start working on his project. He first created an audio CD, then he perfected the CD-ROM, and by 1973, there was a video disc in his hands.

19. Ballpoint Pen

A ballpoint pen is a writing instrument that works on pretty much all surfaces. Unlike a fountain pen, a ballpoint pen can write on leather, wood, coarse paper, etc. It dries quickly and is smudge-proof too. The phenomenon behind this device is a free-moving ball on the nib of the pen which cannot come out or go in but can rotate in its place easily. Based on this idea, John J. Loud invented the first ballpoint pen in 1888. However, it was not a practical invention.

The first ballpoint pen to be sold was one created by Laszlo Biro, hence the alternative name ‘Biro’ used for ballpoint pens. This happened in 1938. The ballpoint pens manufactured today are based on Biro’s invention.

20. Polio Vaccine

Did you know that there has been a 99% decline in polio cases since 1988? Had it not been for the polio vaccine, 17 million people who are healthy today would have been affected by polio. The credit for this lifesaving invention goes to Jonas Salk. His vaccine was approved in 1955. Later, an oral vaccine was introduced by Albert Bruce Sabin in the 1960s. This new vaccine quickly replaced Salk’s since it was commercially viable and also easier to treat patients with.

21. Helicopter

The first helicopter that this world saw was designed by Igor Sikorsky with a single main rotor and a tail rotor. It was built by the Vought-Sikorsky Aircraft Division in 1939. In September of the same year, this helicopter flew for the first time, although it was only for a couple of seconds. However, in 1940, an improved version of this helicopter flew at a speed of around 300mph. This VS-300 helicopter is still on display in the Henry Ford Museum.

22. Toaster

The crispy bread you enjoy in your breakfast is a luxury that only the people who came after the 20th century have enjoyed. There were no toasters before the 20th century. Actually, there was the Eclipse Toaster that was invented in 1893 by Alan MacMaster in Scotland. However, the first official toaster in the USA was made by Frank Shailor in 1909 and he is the one who got the patent for it. These toasters did not pop-up automatically. In fact, the user had to turn over the bread himself and once the bread was toasted, the device had to be turned off by hand too. A pop-up toaster only came in the market in 1919 after being invented by Charles Strite.

23. Electricity

The best was saved last. Most of the inventions mentioned above are useless without electricity. Fortunately, in the early 20th century, the concept of electrical power generation and distribution was expanded, which is what led to thousands of other creations. Originally, electricity was invented in the 1700s by Benjamin Franklin. However, the use of electricity was neither feasible not accessible.

The major work regarding electricity generation had been done in the late 19th century. The transmission of larger electricity units began within the first decade of the next century. Slowly but gradually, coal and oil generated power sources were replaced with electricity. Eventually, the feasible distance of transmission increased, the technology improved, and today, the entire world is lit by this invention.
