The Pursuit of Truth

Sir Isaac Newton was the most significant figure of the ‘Scientific Revolution’ of the   seventeenth century. His legacy shaped our understanding of mathematics and physics and helped define the modern world.

However, while few people will be unaware of his reputation as a scientist, many do not know that he was Master of the Mint for nearly three decades. When he was appointed Warden of the Mint in 1696, at the age of 53, Newton was already a world-renowned scientist. His greatest achievements include the invention of calculus, the ‘mathematics of change’ that enables us to understand the behaviour of objects as tiny as electrons or as large as galaxies. His Mathematical Principles of Natural Philosophy, published in 1687, is the single most influential book on physics ever written.

As the leading light of a new generation of scientists Newton focused on the search for general laws and mathematically exact data. He brought his pursuit of precision to his role at The Royal Mint and much of his work had a far-reaching effect on our coinage and the British economy.

His meticulous report of 1717, commonly known as ‘the valuation of the guinea’, was pivotal in establishing gold coin as the pre-eminent currency of the United Kingdom. It suggested establishing the gold guinea’s value at 21 shillings which paved the way for the introduction of the gold standard a century later.
