The Principia

 This  335 years  old  masterpiece, by the  influential scientist  of all  time, has contributed  most consequently in  the history of science. This book is often commonly known as “Principia”. We can possibly infer and reach out a place that assures: “no other scientific work has drawn more importance and attention than Newton’s work did” ; in this far pragmatic  globe. The theories proposed are widely ranging in many fields including Newton being mathematician, physicist,  astronomer, theologian and author or say “natural philosopher” and not just being giver of the three laws of motion.

These works have often been used to derive other works such as Kepler's law of planetary motion, the trajectories of comets, etc. The universal law of gravitation is another platinum used primarily even today. It was even justified that the motion of objects in Earth and celestial bodies can also be accounted for, by the same principals. Further, it was added  by the first reflecting telescope and developing a theory stating that prism separates white light into the colors of spectrum and the reason behind it. His inference stating Earth is an oblate spheroid  was also confirmed later, followed by, empirical law of cooling, first theoretical  calculation for the speed of sound, introducing the notion of Newtonian  fluid. The inventions  presented in mathematics also came out as wonders.

Not only these are just theories, they hold applications in our daily life too, and very vastly. Moving things and staying constant, working of airbags in a car, working of  vehicles , flow of  fluids, flying of airplanes, buildings staying static ; all of these are based on these laws and theories imposed by Newton!

 

Concluding, these  theories acted as foundation  for the  keen to know students, scholars and researchers. We see this book with a vision of respect today and roots of inventions tomorrow!
