UNKNOWN PEOPLE WHO CONTRIBUTED FOR THE WORLD

1.Ibn al-Haytham

Born in Basra, al-Haytham was a preeminent thinker of his age. He made valuable contributions in maths, anatomy, astronomy, engineering, medicine, philosophy, physics, and he also introduced a scientific methodology of experimentation and observation. Most important was his work on optics, and his text, The Book of Optics is regarded as being responsible for a revolution in the study of optics and visual perception. His was the first description of acamera obscura (dark chamber), and he also laid foundations for the development of the microscope, the telescope and establishing optical principles of Renaissance art. 

2.Tim Berners-Lee

If it weren't for Tim Berners-Lee, you would not be able to read this article. He is the man responsible for the introduction of the World Wide Web, having developed it as a communication utility while working at CERN, the European Particle Physics Laboratory. Remarkably, he refused to patent his invention, giving it as a gift to the world instead. The internet has since revolutionized the way people communicate, as well as their ability to acquire information and the speed and efficiency with which global commerce operates. His invention was a truly revolutionary moment in communication, with the potential to surpass the discoveries of Marconi and Alexander Graham-Bell. 

3.Avicenna

One of the most influential of all Islamic scientists, Avicenna, like many of his peers, worked on many aspects of science including medicine, maths, logic, and geology to name but a few. He wrote almost 450 texts on a wide variety of subjects, his two most famous being The Canon of Medicine and The Book of Healing. These were used as standard university textbooks across Europe for hundreds of years. However, his influence extended farther, as he is also considered responsible for the introduction of quarantine to avoid spreading infections, as well as introducing clinical trials and systematic experimentation

4.Thomas Midgley

Thomas Midgley is a man who has made a massive contribution to the modern world. Sadly, his contribution was not a positive one. First, Midgley discovered that the addition of lead to petrol stopped the "knocking" effect incar engines. However, this also caused massive health problems globally. Subsequently, he was the man responsible for the development of CFCs, one of the most destructive compounds in our atmosphere today, and a major contributor to global warming. It has been remarked that Midgley “had a greater impact on the atmosphere than any other organism in history.” Sadly for him, but possibly good for the fate of mankind, he contracted polio, and after devising an elaborate pulley system to help him get out of bed, he inadvertently tangled himself up in the strings and strangled himself.

5.James Clerk Maxwell

Acclaimed by some as the father of modern physics, James Clerk Maxwell is a hugely influential figure in the fields of electricity, thermodynamics, photography, nuclear energy, and others. His discovery of the electromagnetic spectrum led to the development of television, radio, microwaves, as well as aiding in the development of radio and infrared telescopes. His equations on the electromagnetic field were essential for the Special Theory of Relativity, by one Albert Einstein. He also produced the first color photograph, a picture of a tartan ribbon. His work actually marked a departure from the work of another great scientist, Isaac Newton, and helped to inform the science behind many of the great technological developments of the modern era.
