Technology, science and inventions have progressed at an exponential rate during the hundred years of the 20th century, more so than any other century. There is no doubt that the 20th century is one of the most remarkable and astonishing periods of human history for its rate of technological advancement, a rate that still continues to this day. In fact, there were so many new gadgets invented and discoveries made in the last century that it’s incredibly difficult to narrow it down to just three without diminishing the rest. However, I believe I have managed to whittle down those three inventions that have had the greatest influence on humanity, both positive and negative.

We began the 20th century with the infancy of airplanes.

They have also revolutionized warfare; turning battle into a long-range affair fought at arm’s length by machines, changing the entire way wars was previously fought. Of course, they’ve also been responsible for leavening whole cities demolished and bringing war to the civilian population – who had rarely been directly affected by war until the 20th century.

Of course, they have been around since World War Two, but back then they were clunky, massively expensive things that had the calculating power of a brink.
