Just two decades ago, in Bangladesh, even landlines were difficult to obtain, let alone mobile phones. Anything that is useful and spreads so fast has to be considered one of the greatest inventions of all time. Today, by some estimates more than 100 million people in Bangladesh and more than 4.6 billion people worldwide have mobile phones. Phones have been around since the late 1800s, but cell phones made their appearance only in the 1990s. When we get there, we will owe, a lot to Robert Jarvik’s artificial heart. One day, more advanced versions of artificial organs will likely allow us to live much longer and more productive lives. Though the patient survived 112 days, it was a huge step towards the development of heart transplant surgery. The Jarvik-7 artificial heart was designed by Robert Jarvik. Barney Clark, was the first person implanted with the Jarvik-7, an artificial heart intended to last a lifetime. Implanting a person with an artificial heart in 1982 was an extraordinary step towards increasing human lifespan. There is nothing- that piques the interest of a human being quite as much as the prospect of living a longer life. With that in mind, it is worth looking back at some of the amazing scientific advances we have made in the last few decades. Perhaps just as extraordinary is how we tend to simply adapt to these incredible changes, not realizing how completely our world has been altered in a short span of time. In other words, the advances humankind has made in a relatively short period of time have been nothing short of extraordinary. Televisions didn’t become widely available until after World War II. Charles Lindbergh made the first trans-Atlantic flight in 1927. Cars just started to become available 100 years ago. It was only in the 1870s when we had the first house that was lighted with electricity. We human beings tend to forget how far we have borne as a species in a relatively short period of time.
