A Pure Vision

Sir Isaac Newton was born in Woolsthorpe, Lincolnshire, on 25 December 1642. At this time England was a chaotic and turbulent country, torn apart by civil war, religious unrest and the threat of plague. When Newton became a student at Trinity College, Cambridge, in 1661, undergraduates still studied the work of ancient authors such as Aristotle and Plato. However, by this time, their doctrines were being seriously questioned by inquisitive minds like the young Isaac.



Although Newton initially studied the work of these great figures, he was one of a new breed of ‘natural philosophers’ whose approach to science was defined by the use of rigorous experimentation and mathematics. His work was built on the belief that:

"Plato is my friend, Aristotle is my friend but my greatest friend is truth.”


 

 

As the leading light of the seventeenth century’s ‘Scientific Revolution’, he helped shape the way we think today. He invented calculus and proved that white light is made up of primary colours. His `Mathematical Principles of Natural Philosophy` remains the most important book ever written about physics and contains his revolutionary mathematical description of the universe.

Most people know him best for the story of the apple falling from a tree in his garden, inspiring Newton’s law of ‘Universal Gravitation’ that informs our understanding of gravity. But his influence on our lives today goes far beyond that.


His clarity of vision shaped his life’s work and also drove his commitment to, what he called, ‘the king’s business’ at The Royal Mint.

 

A Scientific Quest for Accuracy

 

From 1696 until his death in 1727, Newton was first Warden and then Master of the Mint. He applied his scientific precision to the task of improving the accuracy of the coinage, making it difficult for counterfeiters.

Newton also took it upon himself to bring these criminals to justice, often rooting out and prosecuting them himself. This quest brought him into contact with many criminals. One being the notorious counterfeiter William Chaloner, who eventually paid the price for underestimating the Warden when he was put on trial, found guilty and hanged.

In 1717 he was commissioned to produce a report ‘On the State of the Gold and Silver Coin’. This effectively fixed the value of the guinea at twenty-one shillings and marked an important step towards the eventual adoption of the Gold Standard. This, in turn, led to the re-introduction of The Sovereign, which has gone on to celebrate 200 years as one of the world’s most iconic and best-loved coins.

Newton endeavoured to make all coins made at The Royal Mint as accurate and reliable as possible, reducing variances to such a degree that The Royal Mint would be beyond criticism. His dedication to accurate coin production and scrupulous scientific testing meant that coins made by The Royal Mint became the most respected in the world. It is a reputation we are proud to maintain to this day.

“The proper method of inquiring after the properties of things is to deduce them from experiments.”

He refused to accept any criticism on the quality of his coins, as shown by his reaction at the Trial of The Pyx in 1710. This ceremony sees an independent jury weigh and assay a selection of Royal Mint coins. When it was reported that The Royal Mint's gold coins were not quite as they should have been, Newton flew into a rage. He insisted the coins were not at fault and questioned the standard trial plate they were being measured against. Newton proved his point and the faulty plate was quickly abandoned.
