To invent, you need a good imagination and a pile of junk. – Thomas Alva Edison
In the last few centuries, there have been inventions that have re-defined mankind. These inventions have made our lives easier and often we forget to think about these inventions or people behind these inventions. While the invention of post-it may not wow us but imagine sticking notes on wall and fridge with Sellotape (which in itself is an invention!). There are inventions that were accidental but there have been inventions behind which a lot of effort and brain was put in. Lets have a look at 5 inventions that changed our lifestyle and perception.
Please note: This list could be missing inventions that are equally important.
#5 Printing Press
Most of us take books for granted. Who’d read those long, boring printed pages with no pictures, right? What we don’t realize is that printing press revolutionized the world. Earlier the writer/author had to manually write the book and make several copies by hand-only. The numbers were limited and education was finite. Johannes Gutenberg invented the printing press which increased the accessibility of education.
It happened in 1450 AD during Renaissance. A lot of cultural and social changes in Europe kindled the spark of producing inexpensive methods to produce documents in a large number. To subsist with the changing times, technology flourished and an efficient printing press was developed. The invention of printing press brought about a lot of evolvement since the bible was written in various different languages and many opinions raised reached a larger audience which boosted the sharing of literature globally.
We can’t live without our mobile phone for a minute. We get agitated when we don’t find the phone in our hand bag or underneath our pillow. Long before mobile phone invention, Alexander Graham Bell invented telephone. Telephone is a system that converts sound into series of impulses of different frequencies and then reverses the procedure. As complex as it sounds the invention took time and dedication of Bell. Invented in February 14th, 1876, two individuals in the U.S filed the patent for creating this instrument. Graham Bell beat Elisha Gray by two hours. Letters were the only means of personal communication prior to the invention of the telephone.
Although now it is considered romantic, it was an exasperating and uncertain process back in the days. Telephone made the communication system faster and certain.
#3 The Light Bulb
The inventor of electricity, Sir Thomas Alva Edison, flew a kite in a stormy weather with a metal key attached to the end of the string. When the electric current passed through the string, Sir Edison touched the metal key, felt the electric shock which went down his entire body, entering the ground which on further research developed into the concept of Earthing. Thomas Edison tried various filaments of different materials over and over again to come up with one definite long lasting solution for getting light. After plenty of trials, Edison finally ended up with a light bulb that glows up to 1500 hours. The light bulb did not only change the world by providing source for people to work at night, it changed the world because it provided a groundwork to facilitate every home with electricity.
#2 Number Zero
Envision a situation where your salary has no zeros. Erasing even one zero to an amount would change the entire sum inordinately. The number zero, as we know it, wasn’t actually invented by Aryabhatta. It was, in fact, Brahmagupta who invented zero 1500 years ago but for different reasons. He used dots underneath the numbers to indicate a zero. It is also called sunya which stands as a symbol of nothing-ness, indicating that it’s empty. Then came Aryabhatta who was a great mathematician. He was computing his complex arithmetic calculations where he got stuck. He kept trying and trying and after about 200 trials he realized the incompleteness of the digits and came up with an assumed number which is now called zero. A digit, which on its own holds no value, can add or subtract great values when combined with other numbers. Such is the power of zero.
With a statistic increment in the demography of the world, a solution to control it was absolutely called for. Although the Vedas mentioned many natural contraception methods for women, most of us are either not aware of it or are very lethargic to follow the ayurvedas regularly. While you may think that condoms are being used only since the past few decades but they aren’t as modern as we think they are. The invention of condoms date back to 3000 years ago when the Egyptians created them from animal tissue, usually their intestine or bladder or membrane of the fish. Further development lead to condoms being made from vulcanised rubber during the 1840s. Gross as it sounds, these condoms could be washed and reused. Then came our modern condoms which are not reusable, made from latex and are disposable.
