Albert Hyunsung Shim to Publish New Mathematics Book Explaining Why dy over dx Behaves Like a Fraction

Published

on

Albert Hyunsung Shim, founder of the Institute for Mathematical Research, which has offices in both Korea and the United States, is set to release a new mathematics book this August titled “Why dy/dx Acts Like a Fraction”, which offers a rigorous explanation of the true nature of the derivative notation dy/dx.

[Albert Hyunsung Shim]

In this upcoming work, Shim reveals that although dy/dx is not technically a fraction, its behavior can be mathematically justified as if it were one—based on the concept of limits, the foundational idea behind calculus. His research sheds new light on a symbol that has been used repeatedly in calculus education from high school to university, often explained only through intuition or memorized rules.

For generations, students have accepted identities such as “dy/dx = (dy/du) × (du/dx)” and “dy/dx = 1 / (dx/dy)” as axiomatic or purely intuitive without seeing a formal justification. Even Gottfried Wilhelm Leibniz, credited with introducing the notation, is not known to have provided a rigorous rationale for its structure.

Shim seeks to overturn this longstanding gap in mathematical pedagogy. His book reconstructs the internal logic behind dy/dx by employing the mathematical definition of limits. In doing so, he demonstrates the logical necessity for dy/dx to behave like a fraction, not just in appearance but in the underlying reasoning.

The author anticipates that his findings will have practical implications in math education. By offering students a conceptual framework grounded in mathematical reasoning, rather than rote memorization, the book could foster deeper understanding of calculus and its foundational principles. The book will be published both in Korea and internationally. An accompanying academic paper is also expected to become a valuable resource in the field of mathematics education.

The book has already garnered early praise from academic circles. Professor Hemant K. Singh of the Department of Mathematics at the University of Delhi, a leading institution in India, shared his thoughts after reviewing the manuscript.

“This work is a game changer, particularly for the new learners of differential calculus. It makes the operation of calculus so mind-blowingly intuitive that the students do not have to remember all its nitty-gritties. The results are thoughtfully derived from the fundamental rules of calculus. This  research is indeed made-easy for both the teachers and the students.”

Albert Hyunsung Shim is a seasoned author of mathematics textbooks widely used in the U.S., particularly for AP Calculus and international math competitions. He currently heads the Institute for Mathematical Research and is slated to serve as a question setter for the Indian Mathematical Olympiad starting this fall.

“Mathematics derives its true value from uncovering and applying the logical structures that lie beneath its surface,” said Shim. “I hope this book inspires students to appreciate the inherent beauty of mathematics in a new way.”

BIRMINGHAM, England, 10th Oct. Sunhome, a leading global solar solution provider of integrated home solar and storage systems, took a significant step to elevate its profile in the British market with a successful exhibition at Solar & Storage Live in Birmingham, happening from 23rd September to 25th September.

This event served as a platform to unveil Sunhome’s full suite of residential solar solutions designed for UK households, highlighting the company’s game-changing one-stop-shop strategy.

 In the UK, many homeowners face fragmented energy solutions — systems built from components supplied by different manufacturers often result in inconsistent quality, complicated installation, and unclear after-sales responsibilities. Sunhome’s newly introduced one-stop residential solar solution directly addresses these challenges. This integrated system combines high-efficiency solar panels, inverters (3kW–6kW), and batteries (5kWh–20kWh), along with heating integration. By offering a fully unified system from a single brand, Sunhome redefines the residential solar experience—ensuring reliability, simplified installation, and seamless after-sales support for every household.

 Placing safety at the forefront, the Sunhome Smart Energy System is equipped with 24-hour monitoring of key electrical parameters, including leakage and overload protection. Its three-level defense system—early warning, threshold alerts, and protective shutdown—provides comprehensive real-time protection. Furthermore, the system’s precise arc detection and ultra-fast disconnection capabilities exceed industry safety standards, establishing a new benchmark for home energy protection.

Beyond the product showcase, a key highlight was the demonstration of Sunhome’s proprietary AI-powered modelling software, iSolarRoof, which leverages Google Maps to perform remote roof assessments and generate customized system designs. This innovation reinforces Sunhome’s commitment to technology-driven solutions and positions the company as a leader in delivering accurate, transparent, and tailored energy plans for homeowners.

 Looking ahead, Sunhome also showcased its balcony photovoltaic storage system—a forward-thinking solution designed to serve the flat-dwelling market once UK regulations permit. This move highlights the company’s proactive approach and vision as an industry innovator.

James Jara New Book Empowers CTOs and HR Leaders to Build High-Performing Remote Teams Across Latin America

Published

on

Technology strategist James Jara’s new book, Nearshoring Staff Augmentation in Latin America, reveals how companies can tap into Latin America’s skilled tech talent to build scalable remote teams, reduce costs, and drive innovation through trust-based partnerships across Mexico, Colombia, Brazil, Argentina, and Costa Rica.

 James Jara’s new book, Nearshoring Staff Augmentation in Latin America

 

As global businesses search for new ways to scale efficiently and attract top-tier talent, James Jara’s new book, Nearshoring Staff Augmentation in Latin America, arrives as a timely roadmap for technology executives, HR leaders, and founders rethinking their global strategy.

The book explores how the rapid digital transformation of Latin America has positioned the region as one of the world’s most strategic talent hubs. Through real-world experience and data-driven analysis, Jara outlines how companies can reduce costs, expand capacity, and maintain product quality through nearshoring — without sacrificing cultural alignment or operational control.

Drawing from more than a decade leading software ventures across LATAM, Jara details how nearshoring staff augmentation works in practice — from evaluating partner countries like Mexico, Colombia, Argentina, Brazil, and Costa Rica, to establishing effective cross-border workflows. He explains how organizations can blend agility with structure, mitigate timezone challenges, and create distributed teams that perform at Silicon Valley standards.

“We’re witnessing a massive shift in how and where innovation happens,” says James Jara. “Latin America has the skills, energy, and proximity to become the natural extension of the world’s top tech companies. This book gives leaders the playbook to make that transformation a reality.”

Beyond the technical frameworks, Nearshoring Staff Augmentation in Latin America explores the human side of collaboration — emphasizing trust, cultural synergy, and long-term sustainability over short-term outsourcing tactics. Jara encourages executives to see nearshoring not just as a cost-saving model, but as an opportunity to unlock innovation through relationships built on shared values and vision.

The book positions Latin America as a vital player in the future of global technology, driven by a new generation of bilingual engineers, designers, and innovators ready to operate at global scale.

Nearshoring Staff Augmentation in Latin America: Unlocking Market Opportunities for Businesses and Startups is available worldwide in paperback and ebook formats. Readers can learn more at James Jara Nearshoring Staff Augmentation in Latin America or purchase it directly on Amazon Nearshoring Staff Augmentation in Latin America Book.
