7 Indian women scientists who are an inspiration to all

While history is full of stories of famous inventors, who are often national heroes, in almost every case they were just the first people to improve an existing system to the final stage where it achieved mass appeal. Think of how scientific discoveries from hundreds of years ago inspired the works of subsequent generations of scientists. In the video above, we find out about 10 famous inventions that were the culmination of efforts by dozens or hundreds of people:. Allegedly, Galileo heard about these and decided to build his own, even making some improvements in the process.

He was also the first person to use these new optics as a scientific instrument, which is where his real value was added. Englishman Thomas Savery patented the first steam engine design in , to remove water from coal mines. Subsequently, Thomas Newcomen improved the design to work at atmospheric pressure, which became the standard design for about 50 years.

During times of slavery in the USA, Georgia predominantly grew cotton which had shorter fibres. So the state of Georgia sponsored an engineering push to come up with a better design. While this significantly improved the production ability for cotton, it also had the sad side effect of increasing the demand for slaves to man the fields.

Devices capable of lifting people into tall buildings have existed since the ancient Egyptians. And as the industrial revolution and the growth of cities led to taller buildings being constructed, people became tired of having to climb multiple flights of stairs. So elevators were invented, using either steam or electric engines which pulled up elevators with ropes.

However, ropes have a tendency to break. And even being in an elevator only a few storeys high, if the rope broke and you plummeted with the carriage it would result in at least severe injury, if not death.

Otis actually invented the safety break, which would stop the elevator from crashing if it was activated by sudden falling when a rope broke. This removed a major risk of death from buildings taller than a few storeys, and spurred on the building of the first skyscrapers. It is perhaps the most famous invention of all time, and its symbol actually epitomises the concept of an idea. Not the glass bulb, or the glowing filament inside it. He merely improved the previous designs to the point that they became commercially practical, in In , Joseph Swan found that carbonised paper was a much better material for a filament and used them to make light bulbs.

After further experimentation, both Swan and Edison found subsequently better materials, and eventually their two companies merged to market their new improved design together, though most people only remember Edison. In the s, both Marconi and Nikola Tesla were fighting to develop the radio.

Tesla actually received more of the early patents for the technology. However, the initial discovery of electromagnetic radiation was actually made a decade earlier by German scientist Heinrich Hertz, who was able to both transmit and receive radio waves in his lab.

It was later Marconi who was able to take all these technologies and turn them into a commercial product. Ford released the Model T in , and it was the first car to gain mass market appeal and success at a time when many people still travelled by horse. However, the car as powered by an internal combustion engine was actually created by Karl Benz in , and many other engineers subsequently improved on the design for better efficiency, comfort and performance.

What Ford achieved was improve the production process of the machine. His assembly line improved production efficiency significantly, bringing down the cost of each unit to a price point where people could actually afford it. Humankind has been dreaming of flight for eons. And the Wright Brothers were not the only people of their time to try and develop a machine capable of powered flight. Another engineer called Otto Lilienthal then used a lot of those designs to create actual gliders with fixed wings and testing them, producing a lot of data which the Wright Brothers would subsequently use.

Additionally, the Wright Brothers were able to use another recent invention from the time: the internal combustion engine from automobiles. They were around at just the right time when this became available. Their true innovation was in their designs which allowed their plane to actually be steered and controlled. And the rest is history. An excellent example of an invention that was only possible thanks to numerous other inventions across industries.

Farnsworth was able to take the developments of the cathode ray tube by Ferdinand Braun and combine it with a way to scan images using electrons which he apparently began thinking of in high school.

Early computer systems were primarily command-line driven, meaning you needed to know all of the inputs to type into a keyboard to tell the machine what you wanted it to do. Many people credit Microsoft Windows with introducing the world to the Graphical User Interface GUI , where you can use a mouse to click on-screen objects to tell it what to do, making the whole process much more user-friendly.

However, a lot of the progress in GUI development happened much earlier. A pioneer was Douglas Engelbart, who demonstrated an Operating System with a mouse pointer in This idea was then taken up by Xerox, who released their Alto computers which were the first with a mouse and GUI.

This then paved the way for the more business-focussed Microsoft Windows Operating System, which took the idea truly mainstream. Invention is a process that continuously builds on what came before it.

While an individual may have a stroke of genius, these moments never happen in a vaccuum. Often, the best innovations are the ones which take previous ideas and find new ways to add value that the customers love.

Chief Editor of Ideatovalue. Fletchr currently operates in four countries, but they are sure to be expanding to more very […]. Thanks for great article. It is quite a common belief that Italian astronomer Galileo Galilei invented the telescope but this is not strictly true. The earliest workings towards the design of the refracting telescope were made by German-Dutch lensmaker Hans Lippershey above in Fantastic inventions are there they made like — light bulb , car , telescope , elevator , T.

V , airplane,radio etc. And who invented digital Pre-press or we should ask which technology led to it? Computers, Inkjet printing or Graphic Arts? Who make this list where is tesla?

Tesla is inventor he knew that the a common people can benefit his inversion in the real he was the great inventor of all time….. Steve Jobs and a smartphone. Hint — smartphones existed for quite a while before iphone, despite what many people think. Amazing thinkers. We are cant tell, that who first invented the things, after a deep research we came to know that every first invention has the story before them… Like watch invention, wheel..

As Isaac Newton so famously said in If I have seen further, it is by standing on the shoulders of giants In the video above, we find out about 10 famous inventions that were the culmination of efforts by dozens or hundreds of people: 1. Galileo and the telescope Galileo Galilei. Watt steam engine. Thomas Edison Light Bulb. Guglielmo Marconi radio. Philo T Farnsworth. Ahh, my youth. I grew up on Windows 3. Apple Podcasts.

14 Indian Scientists Who Changed The World. And Things You Probably Didn’t Know About Them!

Jump to navigation. There have been many physicists whose inventions and contributions have changed the face of science, and India is a proud home to many of them. Their works, methods, procedure and theories are been studied and taught all over the world. We present to you the top 10 Indian physicists and what makes them different:. Sir Chandrashekhar Venkat Raman or C. Raman, as he was called, is remembered for his revolutionary contribution to physics.

Like most professions in India, the field of science is very much male-dominated. Many women, over the years, have made immense contribution to science, and have also paved a path for others to follow. Let us look at seven Indian women scientists who have broken stereotypes and are an inspiration to all. One of the few women mathematics researchers in the country, she completed her PhD, 16 years after marriage. She has been honoured with the Vishwanath Parvati Gokhale Award for one of her books in Marathi. Also a teacher, she is popularly known for the way she makes mathematics an interesting subject for her students. Aditi is an oceanographer, and the first Indian woman to travel to Antarctica, as a part of the Indian expedition, to study geology and oceanography.
