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?
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 Image result for first 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.
