‘Science is Nothing but Perception’, said by Plato.

New discoveries and inventions are the basis of human development, it is basically a process detecting something new or something “old” that had been unrecognized as a relevant element. There are many examples in the history where something else was under research and consequences gave birth to completely different and useful invention.

Here we have listed up 7 discoveries that became invention eventually:


Mistakes are an indispensable part of human nature but what if your mistake become an extreme invention? Yes, it’s amazing to hear and it actually happened with Wilson Greatbatch’s case, his mistake became a result of the first practical implantable pacemaker.

Greatbatch was actually working on a circuit that could record fast heartbeats but when he accidentally installed the wrong resistor the device started giving electrical pulse and he discovered pacemaker.


Can you imagine yourself eating your delicious cheesy food without the help of microwave?  No, you cannot. But do you know how microwave was invented?

The microwave was discovered in 1945 by Percy Spencer an American engineer working for the company Raytheon. Spencer was working on a magnetron capable of beaming high waves of radiation when he noticed that a chocolate bar in his pocket had melted. Curious, he placed a bowl of popcorn in front of the tube and it began to pop. Spencer then created a high-density electromagnetic field by feeding microwave power from a magnetron into a metal box from which it could not escape.

Later, Raytheon patent the accidental discovery and in the year 1947, launched it in  the market as a new technology.


X-Rays are one of the most important discoveries of medical science but it is again an accidental dicovery yes, X-Ray is a radioactive invention that discovered accidentally. In 1895 physicist Wilhelm Röntgen was investigating the properties of cathode rays. Accidentally, he noticed a flicker on a barium platinocyanide screen. It was a surprise when he saw a skeletal hand.  As the invention of X-Rays took place accidentally.


We all are familiar with cellophane that is a thin transparent sheet. There are many applications of cellophane, such as the production of self-adhesive tape, scotch tape, and the colorful cellophane covers are being used for the school going children.

But Do you know how it invented? It was an accidental invention. Jacques Brandenberger, a Swiss chemist has discovered Cellophane but he was not purposely searching something like cellophane, he was looking for a way to make a stainproof tablecloth. He tried coating the cloth with a thin sheet of viscose film, and later he realized that the film could be used in several ways. Consequently, he researched further and finally discovered Cellophane.

Vulcanized Rubber

Vulcanized rubber was an accidental discovery.

Initially, the freezing temperatures and extreme heat left consumers and manufacturers frustrated. And people started believing that rubber has no future, but the scientist Charles Goodyear disagreed and worked on it to make rubber more durable. Later, in 1839, when showcasing his latest experiment, Charles accidentally dropped his rubber concoction on a hot stove. And consequently, he discovered charred leather, a substance with an elastic rim. Now, Rubber is more durable and weatherproof.


Velcro is a combination of the words ‘Velvet’ and ‘Crochet’. It is again an invention that has discovered accidentally. On a hiking trip in 1941, Swiss engineer Georges de Mestral found burrs clinging to his pants and also to his dog’s fur. He found that the burr’s hooks would cling to anything loop-shaped. If he could re-create the artificial loops, that can be helpful. So, as Velcro invented accidentally.
