Foundations of Advanced Mathematics

Isaac Newton, by the age of 24, had laid down the essential groundwork for what would come to be known as calculus. His method provided a systematic approach for understanding change and motion, forming the backbone for later developments in mathematics and the sciences. This achievement continues to underpin a vast range of disciplines, from physics to engineering.

Key Outcomes:
- Precise tools for examining change
- Applications in fields such as physics and technology
- Foundations for mathematical analysis

Exploration of Light’s Nature

Newton’s early experimentation revealed that light was far from simple. Instead, he demonstrated its intricate structure, showing that white light is actually composed of various colors. His work included breaking down light with prisms and exploring its properties, changing previous ideas about how light and color function.

Practical demonstrations used by Newton:

Experiment Result Use of a prism Display of spectrum Color recombination Restoration of white light

A New Understanding of Gravity

Newton was among the first to describe a universal principle that governed the attraction between objects: gravity. His efforts set out a consistent explanation for the motion of planets and objects on Earth, giving a unified account that had never been attempted before. This principle unified celestial and terrestrial mechanics under the same set of laws.

Summary of implications:

Explained planetary orbits and tides
Provided a predictive framework for natural phenomena
Influenced future research in physics and astronomy

The Disclosure of Newton's Private Manuscripts

Auction at Sotheby's and the Fate of Newton's Notes

On July 13, 1936, London witnessed a rare event: the personal writings of Isaac Newton were put up for public sale at Sotheby's. The auction was organized after the 9th Earl of Portsmouth, facing financial problems, decided to sell a metallic chest packed with thousands of Newton's handwritten pages. Despite the historic significance—over 10 million words in total—the sale attracted little attention.

Key Details of the Auction:

Item Description Date July 13, 1936 Auction House Sotheby's, London Volume of Papers ~10 million words, handwritten Sale Price £9,000 total Outcome Sold piecemeal to many collectors

For decades, these manuscripts had been hidden by Newton's descendants due to their controversial contents. The lack of publicity meant these documents, priceless by any standard, were dispersed quietly among private buyers.

The Find by John Maynard Keynes

Among the few who acted on this unexpected opportunity was John Maynard Keynes, the renowned economist. Arriving late to the auction and learning of it just in time, Keynes still managed to acquire about 10% of the manuscripts. This purchase sparked his enduring fascination.

Keynes was astonished by what he read, and spent his remaining years seeking the rest of Newton's papers, eager to reconstruct a complete picture of Newton's intellectual pursuits beyond his celebrated scientific achievements.

Revelations About Newton's Secretive Pursuits

Examination of the manuscripts changed the narrative around Newton's life and priorities. Less than a third of his writing involved mathematics or physics. The majority centered on two areas:

Religious studies, particularly his unorthodox theological views
The study and practice of alchemy

Newton challenged the doctrine of the Trinity and dedicated millions of words to religious analysis, including attempts to uncover coded secrets in biblical texts. His anti-trinitarian views would have been considered heresy at the time, placing him at serious personal risk.

In alchemy, Newton devoted himself to the pursuit of transforming metals and seeking hidden truths about nature—an area then regarded as both mystical and, in many cases, illegal. These interests were so sensitive his heirs kept them secret for over 200 years, fearing the potential consequences of disclosure.

Doctrinal Convictions and Unorthodox Beliefs

Rejection of the Trinity

Newton privately dismissed the conventional doctrine of the Trinity, holding the belief that God is not divided into three co-equal persons. In his view, Jesus Christ was a man rather than a divine being, and venerating him as God amounted to idolatry. Such perspectives directly conflicted with accepted church teachings of his era and carried serious personal risks.

Key points:

Denied the traditional concept of Father, Son, and Holy Spirit as equals
Classified worship of Jesus as improper
Maintained these beliefs in secret due to potential consequences

Pursuit of Scriptural Secrets

Newton became engrossed in deciphering what he perceived as concealed codes within the Bible. He was convinced that ancient wisdom was encrypted in religious texts and that it was his duty to discover these hidden meanings. This obsession led him to pour years into analyzing scriptures, hoping to unlock mysteries about existence and the universe.

Areas of focus:

Area Description Hidden codes Searched for messages or patterns embedded in scripture Ancient knowledge Believed secrets from antiquity could be uncovered Personal mission Felt he was chosen by God for this task

Calculating the End of Days

Using data he extrapolated from the Book of Daniel, Newton attempted to forecast the timing of the world’s end. He applied a methodical, almost scientific, approach to interpret prophecy and compute when humanity’s final days might occur. While he could not specify an exact date, he suggested the apocalypse would likely take place before 2060.

His timeline for the apocalypse reflected his drive to blend religious conviction with analytical reasoning.

Newton’s Interest in Alchemical Studies

What Drove Newton Toward Alchemy

Newton’s fascination with alchemy extended beyond idle curiosity. He devoted significant energy to exploring methods for changing ordinary metals into gold, the hunt for a universal medicine, and the legendary elixir that granted eternal life.

His commitment is evident in the scale of his notes—meticulous records, lists of experiments, and tables of substances filled thousands of pages. For Newton, alchemy blended elements of science, religious belief, and secret wisdom, reflecting his sense that he was chosen to uncover truths hidden from the ordinary person.

Dangers and Legal Consequences of Alchemy

In Newton’s era, the secretive nature of alchemical research was not just for science’s sake. Alchemical activities, especially the attempt to manufacture gold, were strictly outlawed. Laws targeted alchemists because their pursuits threatened economic stability and carried associations with sorcery.

Discovery carried harsh penalties. Newton and fellow practitioners knew exposure could mean imprisonment—or even execution. This climate of risk drove him to keep his research hidden from colleagues and the public, with generations of his descendants continuing to guard his alchemical papers in secrecy long after his death.
