Introducing Historical

From Swords to Smartphones?!

In the heart of modern Seoul, an unexpected twist turns Sena’s life into a whirlwind adventure when a medieval stone tower appears in her best friend I-seo’s backyard. This enigmatic event introduces Sena to Luke and Amiel, two figures from another realm who have stepped right out of I-seo’s novel “Between Two Blades.” The book depicts a tragic BL love story where a saint, destined to save the protagonists, ultimately betrays and kills them—a narrative yet to unfold as they find themselves inexplicably in Seoul. Prince Luke, with his dignified demeanor, and Amiel, both angelic and disturbing, find themselves lost in the complexities of the modern world. Their tragic destiny, as written by I-seo, looms over them, filled with unresolved tension and the threat of a doomed ending. Sena, armed with her practical spirit and I-seo’s intimate knowledge of her own characters, takes on the challenge of merging these contrasting realities. The medieval newcomers draw a mix of attention and conflict, compelling Sena and I-seo to navigate through a maze of urban escapades to keep them safe from both medieval pursuers and the public eye. As they struggle with these extraordinary circumstances, Sena uncovers a surprising link between her family and the historical figures: her grandmother, Hyejin, has a hidden past with the medieval visitors. This revelation binds her family’s story with the fantastical disruptions rippling through their lives.

Abraham–Lorentz force

Book Blurb: Abraham–Lorentz Force Delve into the intricate world of electrodynamics with Abraham–Lorentz Force, a comprehensive exploration that spans over a century of scientific discovery. This book takes you on a journey from the foundational principles of classical electrodynamics, as established by Maxwell and Lorentz, through the early developments in radiation reaction and the formulation of the non-relativistic Abraham–Lorentz force. It then ventures into the realm of relativity with detailed analyses of the Abraham–Lorentz–Dirac equation and its modern extensions, including alternate formulations such as the Landau–Lifshitz approach. At its core, Abraham–Lorentz Force bridges the gap between theory and experiment. Readers will discover advanced theoretical perspectives, delve into experimental investigations that test these ideas, and explore how collective phenomena in plasmas and quantum theories converge to shape our understanding of self-interaction. The latter chapters address future directions and unresolved questions, challenging the reader to consider the classical–quantum transition, self-force problems in quantum gravity and string theory, and even the quest for a grand unified theory. Structured into twelve meticulously organized chapters, the book begins with: • Chapter 1: Foundations of Classical Electrodynamics – Laying the groundwork with Maxwell’s equations and the Lorentz force. • Chapter 2: Early Developments in Radiation Reaction – Tracing the pioneering work that first identified the self-interaction of accelerating charges. • Chapter 3: The Non-Relativistic Abraham–Lorentz Force – Analyzing the classical self-force in low-speed regimes. • Chapter 4: Relativistic Extensions and the Abraham–Lorentz–Dirac Equation – Extending the theory into the relativistic domain. • Chapter 5: Alternate Formulations and the Landau–Lifshitz Approach – Introducing pragmatic alternatives that avoid pathological predictions. • Chapter 6: Advanced Theoretical Perspectives – Exploring cutting-edge ideas that push the boundaries of current models. • Chapter 7: Experimental Investigations and Observations – Reviewing key experiments that validate and challenge theoretical predictions. • Chapter 8: Collective Phenomena in Plasmas – Examining how self-interaction affects the dynamics of complex plasma systems. • Chapter 9: Connections to Quantum Theories – Linking classical concepts to quantum electrodynamics and beyond. • Chapter 10: Future Directions and Unresolved Questions – Highlighting emerging research frontiers and ongoing challenges. • Chapter 11: Appendices – Providing essential mathematical identities, notational conventions, and historical documents. • Chapter 12: Analysis of References in Electrodynamics and Radiation Reaction – Evaluating the significance and impact of seminal works in the field. This book is an indispensable resource for PhD students, researchers, and professionals seeking to gain a deep, nuanced understanding of radiation reaction and self-interaction. It blends rigorous theory with practical insights, supported by extensive historical context and modern experimental evidence. With clear explanations, vivid analogies, and carefully structured content, Abraham–Lorentz Force not only encapsulates the evolution of electrodynamics but also illuminates the future directions of this dynamic field.

Extra's Rise: I Introduced Arms In A World Where Magic Is Useless!

After dying as an orphan in a devastating world war, Keith finds himself unexpectedly transmigrated into his favorite novel, Fallen Mages. But instead of a fresh start, he’s thrown right into the chaos of the great war between the Mages and the Negators—a brutal conflict destined to end in humanity’s destruction. Armed with the grim knowledge of their impending doom, Keith braces for the worst. Except fate had other plans. Now living as Elon, the banished prince and forgotten son of the second queen of a struggling kingdom, Keith soon realizes that his presence has shifted the course of the story. And then, it happens— [This Extra has been chosen after a random selection...] [Congratulations, you have obtained the Weapon Summoning System.] "Weapon...? Summoning...? System...?" "You mean weapons like guns and grenades? Like the kind that goes BOOM?!" "HELL YEAH!" With this newfound power to summon modern weapons, Elon discovers that these arms are the only tools capable of striking fear into the Negators and giving his kingdom a fighting chance. From simple guns to devastating missiles, Elon’s arsenal grows stronger with each battle. Determined to rewrite the fate of this war-torn world, Elon sets out to transform his once-weak kingdom into an unstoppable force. Along the way, he questions everything: What’s wrong with conquering other lands if their rulers were never worthy in the first place? What’s wrong with using power to unite the broken? "An AK-47 can't kill the Third Order Commander? Fine...! Launch the Bazooka!" "The Great Archdemon of Death survived the grenades? Summon the Rocket Team and fire the missile!" "A Twelve-Winged Demonic Dragon shrugged off the RPG-7? Let's introduce it to a volley of Javelin Missiles!" Conquering the world won’t be easy, but with his system, unrelenting ambition, and growing army of allies, Elon is ready to take on every foe—and claim his destiny. Join Elon in his explosive journey as he builds the strongest, greatest, and most fearsome kingdom this world has ever seen.
