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

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.”

New Memoir Oh Wait; That Was NEVER Me! Exposes the Lifelong Impact of Bullying Through a Deeply Personal Lens

Published

on

August 7, 2025

By

New York, NY, A powerful new literary memoir titled Oh Wait; That Was NEVER Me! (The Bully Affect and its Effects) by G.E.B.S. GEBShelton offers a poignant, intimate journey through the long-lasting emotional terrain shaped by childhood bullying. Set against the cultural and social backdrops of midwestern America, this genre-defying work draws from a lifetime of memories, some vivid, some uncertain, to unpack trauma, resilience, and self-reflection.

Structured through a mosaic of themed chapters, the book chronicles the author’s life from a precocious child in Illinois to a reflective adult working in oncology and advanced nursing practice. With unflinching honesty and creative prose, GEBShelton invites readers to witness the inner evolution of a person shaped, yet not defined, by the stigma and silence surrounding childhood bullying.

A Literary Examination of Memory, Pain, and Identity

Rather than a linear autobiography, the memoir reads as a contemplative map of recollections, triggers, and lived realities, blending psychological inquiry with lyrical storytelling. The work explores the nuances of memory and personal truth, questioning how stories are remembered, distorted, or reshaped by time and retelling.

Across more than 30 chapters and bonus essays, the author reflects on formative moments: from living above a dry cleaner and discovering a love for cars, to being labeled a “pansy” in grade school and navigating life as a sensitive, observant outsider. The narrative wrestles with themes of masculinity, artistic expression, familial tension, and the unspoken weight of ridicule.

A Voice for the Bullied, And the Bullies

The book’s dedication, to the bullied, to those considering becoming bullies, and even to non-human creatures like a rooster subjected to pecking order injustice, immediately sets the tone for a work that seeks not revenge, but understanding.

By recounting lived experiences without the shield of anonymity, GEBShelton challenges the reader to consider the origins of cruelty and the quiet devastation of being ‘othered.’ The memoir doesn’t just highlight the scars of bullying; it offers a lens into how such wounds are internalized, buried, and eventually confronted.

A Visual and Sensory Archive

From the lyrical chapter “Life’s Theme Songs” to vivid anecdotes about spiders, prom nights, old Edsels, and dinner table power dynamics, the narrative is rich with texture and visual resonance. The accompanying cover art, a watercolor piece titled “In My Corner” by the author, and photography by Dorothy Shi, further solidify the memoir’s deeply personal and artistic core.

Get To Know The Author

G.E.B.S. GEBShelton is an Adult Health Nurse Practitioner and Oncology Clinical Nurse Specialist with decades of healthcare experience in major medical centers across the United States. Originally from Illinois and now based in New York City, the author brings both clinical insight and poetic introspection to this work, drawing from years of observing human vulnerability from multiple vantage points.

Oh Wait; That Was NEVER Me! joins a limited list of prior works by the author, including The Hand-written Book and Platyfloridanthes Mei, known for their handcrafted artistry and rare production.

Where To Find The Book?

Oh Wait; That Was NEVER Me! is now available in both print and digital formats. Ideal for book clubs, educators, therapists, and memoir enthusiasts seeking a raw and emotionally complex read, the book also includes a dedicated section of discussion questions to encourage meaningful reflection.

New Medigap and Vision Insurance Plans Announced by Wilkerson Insurance Agency in Dallas

Published

August 6, 2025

By

Dallas, Texas, 6th August 2025, ZEX PR WIRE, Wilkerson Insurance Agency, a trusted name in health and life insurance in the Dallas-Fort Worth area for over 20 years, has expanded its offerings with the introduction of new Medigap and vision insurance plans. The move comes as part of the agency’s ongoing effort to provide more complete, affordable coverage solutions for individuals, retirees, and families throughout the region.

“We introduced these new Medigap and vision insurance plans to meet the growing demand for more complete coverage. People want solutions that actually fit their lives, and that’s exactly what we aim to deliver every day at Wilkerson Insurance Agency.”

Spokesperson, Wilkerson Insurance Agency

The newly available Medigap plans are designed to supplement Original Medicare, which often leaves beneficiaries responsible for deductibles, copayments, and coinsurance. These out-of-pocket costs can add up quickly, especially for seniors managing chronic conditions, taking regular prescriptions, or visiting specialists frequently. By offering Medigap coverage, Wilkerson Insurance Agency is helping Medicare recipients access more predictable, budget-friendly care.

“For many people, Medicare isn’t enough on its own,” said a spokesperson for Wilkerson Insurance Agency. “Even with basic coverage in place, there are still gaps that can lead to unexpected medical bills. Our new Medigap plans are meant to fill those gaps and give clients peace of mind, especially as they age.”

In addition to the Medigap rollout, the agency has also launched new vision insurance plans that are available to individuals, families, and small business groups. These plans include coverage for essential services like annual eye exams, prescription glasses, contact lenses, and treatment for vision-related conditions. As screen time increases across all age groups and regular eye care becomes more important, Wilkerson Insurance Agency is aiming to make vision coverage more accessible and affordable for the Dallas community.

“There’s been a growing demand for vision insurance from both younger families and older adults,” the spokesperson added. “Many people are surprised to learn that vision care often isn’t included in their health insurance. These new plans give our clients a way to protect their eye health without adding unnecessary strain on their budget.”

Both the Medigap and vision insurance plans are being introduced with Wilkerson Insurance Agency’s signature hands-on approach. Clients can expect personalized guidance from local agents who take the time to understand each person’s needs and recommend plans accordingly. Rather than offering cookie-cutter options, the agency works with multiple top-rated carriers to match clients with the right coverage at the right price.

With offices based in Dallas and service areas extending to Coppell, Irving, Lewisville, and beyond, Wilkerson Insurance Agency continues to stand out for its client-first mindset and commitment to clear, helpful communication. Their team supports clients not only during enrollment but throughout the year—helping with questions, plan reviews, and updates as life changes.

For individuals who are currently on Medicare or preparing for retirement, the new Medigap plans provide a timely opportunity to lock in supplemental coverage that can reduce out-of-pocket costs and simplify medical billing. And for those managing the healthcare needs of a household, the new vision insurance options add an extra layer of protection to pair with existing health or family health insurance plans.

These offerings are also a strong fit for small business owners seeking to expand their group health insurance coverage options. Vision plans are increasingly popular as an employee benefit, while Medigap guidance can be valuable for older team members or business owners nearing retirement age.

The agency’s team encourages new and existing clients to schedule a free consultation to explore the new plan options and get personalized recommendations. As always, their approach is focused on listening first, then finding solutions that make sense.

Expanded offerings aim to close coverage gaps and provide affordable care options for individuals, families, and seniors in Dallas.

The agency offers a wide range of health, vision, dental, Medicare, life, and group insurance options tailored to individuals, families, and businesses.
