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 ten greatest inventions/discoveries of the twentieth century:
#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 
#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. Source: Toptenz.net
#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. Source: Toptenz.net
#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? Source: Toptenz.net
#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.
