Background / History

In 1665, Little Ox is a young Cambridge student living near Woolsthorpe on his family’s estate, though he relies on his uncle William Askew’s household for meals and support. He allows the stranded Xu Yun—whom he calls “Fat Fish”—to stay in a small cottage, lending him bedding and old school brogues. 8 10 12

He privately holds theological beliefs that differ from accepted doctrine, but lacks the standing to express them openly. Xu Yun’s description of “This Child” resonates strongly with him, making Little Ox markedly more receptive and friendly toward the foreign visitor. 12

Xu Yun’s presence accelerates Little Ox’s work in mathematics and optics. He develops new notation, investigates light through prism experiments, and accepts assistance when Robert Hooke challenges his teacher Isaac Barrow. Their collaboration helps Little Ox solve Hooke’s problem and publicly unsettle his future rival. 23 26 29 32 38

After Xu Yun disappears, Little Ox and the Askew family expand their ketchup business. The resulting dividends grant him financial independence, allowing him to return to Cambridge after the plague recedes. He becomes Lucasian Professor and earns recognition within the Royal Society while producing numerous mathematical and physical results. 211 212

Five years after Xu Yun’s departure, Little Ox sends him a letter describing his advances in calculus and asking for help with light and space-time. Xu Yun’s response pushes him to reconsider corpuscular light theory and absolute space-time; Little Ox subsequently performs a Poisson spot experiment and accepts that light’s nature requires a broader explanation. 211 212

Appearance

Little Ox is a young man with black hair and eyes, thick sword-like eyebrows, and a generally austere expression. He wears a wig and Cambridge formal uniform when attending church or representing Trinity College. 12 26 37 212

• Wore old linen-and-leather brogues from his school days. 10
• Often carried a Holy Book. 27 29
• His wig nearly came loose when he became excited by Xu Yun’s theological remarks. 12
• His hair later turned substantially white while struggling with problems concerning light and space-time. 212

Personality

Little Ox is intensely curious, prideful, and easily frustrated by problems he cannot immediately solve. When blocked mathematically, he punches his desk; when absorbed in research, he neglects food and sleep to the point of nearly drinking ink instead of water. 24 26

He initially divides people harshly by intellectual ability and can be impatient or dismissive. Nevertheless, he recognizes competence when he sees it: Xu Yun’s demonstrations and mathematical knowledge gradually earn his trust, and Little Ox openly asks for help against Hooke. 24 26 29

His loyalty is especially strong toward the people he considers his own. He respects William Askew as family, works alongside Xu Yun rather than treating him as a servant, and takes Hooke’s challenge personally because it targets his teacher, Isaac Barrow. 13 20 28

Xu Yun’s influence softens his more extreme tendencies. Exposure to knowledge from outside his own tradition gives Little Ox greater humility and a willingness to question theories he once considered certain. 212

Abilities & Skills

Mathematical Insight

Little Ox possesses exceptional intuition for abstract mathematics and rapidly builds on new concepts.

• Understood the possible need for a theory of continuously accumulated change while investigating refraction. 24
• Applied Yang Hui’s Triangle to binomial expansions after Xu Yun introduced it. 24
• Optimized notation, including forms equivalent to (a^{1/2}) and (a^{-1}), during his work toward more general expressions. 26
• Developed an understanding of infinitesimals and derived the general relation (F = kx) for steady systems. 32
• Later pushed his concept of limits to a logically rigorous form through his own work. 211

Optics and Experimentation

Little Ox approaches physical phenomena through direct observation, questioning, and controlled experiments.

• Investigated colored distortion in telescopes before Xu Yun demonstrated light dispersion. 22
• Used a prism to observe both the dispersion and recombination of white light. 23
• Determined that different colors have different refractive indices. 23
• Conducted a Poisson spot experiment after receiving Xu Yun’s letter, confronting evidence for the wave nature of light. 212

Academic Debate

Little Ox can remain composed under intellectual pressure and weaponize advanced knowledge against opponents.

• Volunteered to solve Hooke’s challenge himself, giving himself five days rather than passing it to Barrow. 28 29
• Presented a solution to Hooke within four days. 38
• Used knowledge of Saint-Venant’s principle to unsettle Hooke while refusing to reveal everything he knew. 38

Practical Enterprise

Little Ox applies his reasoning beyond scholarship when circumstances demand it.

• Investigated the supposed danger of tomatoes and identified pewter tableware as the likely source of poisonings among wealthy consumers. 33
• Helped introduce and sell ketchup, eventually gaining financial independence through its dividends. 33 211
• Charged Xu Yun a 0.08% daily custody fee for holding his share of the ketchup profits. 211

Equipment / Items

• Holy Book — carried during the encounter with Robert Hooke and treated as something worth defending. 27 29
• Prism and lenses — used in his experiments on dispersion and recombination of light. 22 23
• Gold-wire glasses — received from Xu Yun as part of the completed novice mission. 42
• Axes — used with Xu Yun to cut firewood for William Askew’s household. 12 13

Relationships

• Xu Yun / “Fat Fish” — houseguest, intellectual partner, and eventual friend. Xu Yun guides Little Ox in mathematics and optics, while Little Ox later seeks his advice through letters. 12 22 29 211
• William Askew — uncle and paternal figure. Little Ox helps with chores and depends on William’s household during difficult financial circumstances. 13 20
• Isaac Barrow — teacher and Lucasian Professor. Little Ox fiercely defends Barrow when Hooke attempts to challenge and humiliate him. 27 28
• Robert Hooke — academic rival. Their conflict begins with Hooke’s challenge to Barrow and escalates when Little Ox solves the problem ahead of schedule. 27 29 38
• Lilani Askew — younger cousin within William’s household. Little Ox remains concerned for her well-being after Xu Yun disappears. 212
• Lisa Askew — cousin. In the altered timeline, she accompanies Little Ox through the end of their lives. 318

Story Role / Major Arcs

Meeting Xu Yun

Little Ox shelters Xu Yun at Woolsthorpe, introduces him to the estate and local village, and gradually accepts him after their discussion of theology and “This Child.” 8 10 12

Scientific Awakening

Xu Yun’s demonstrations of dispersion, Yang Hui’s Triangle, and infinitesimal ideas give Little Ox new tools for optics and mathematics. Little Ox transforms these prompts into independent deductions and experiments. 22 26 32

Conflict with Hooke

When Hooke uses Little Ox to provoke Isaac Barrow, Little Ox accepts the challenge himself. With Xu Yun’s assistance, he solves the problem, confronts Hooke in Lincoln, and leaves his rival furious. 27 29 37 38

Ketchup and Return to Cambridge

Ketchup sales improve both the Askew family’s circumstances and Little Ox’s own finances. After the plague subsides, he returns to Cambridge, becomes Lucasian Professor, and begins an accelerated academic career. 33 34 211 212

Correspondence Across Instances

Years after Xu Yun’s disappearance, Little Ox contacts him by letter to discuss calculus, light, and space-time. Xu Yun’s reply changes Little Ox’s future scientific outlook and prevents him from treating absolute space-time as unquestionable truth. 211 212

Notable Quotes

“Fat Fish, I need your help.” 29

“Your mathematical tools are truly astonishing. This is a height I could never reach on my own. Please allow me to offer my highest respects.” 212

Trivia

• Little Ox has two recorded birthdays: December 25, 1642 under the Julian calendar and January 4 under the Gregorian calendar. 11 12
• He was a fee-exempt student at Trinity College. 29
• His later autobiography, My Life, records details absent from the original historical record and helped reshape later biographies in the altered timeline. 244
• He had no surviving offspring despite being married in the later timeline. 239
• A family portrait drawn by Little Ox and Lilani depicts Xu Yun in a deliberately unflattering manner, apparently as revenge for Xu Yun’s unannounced departure. 318
