Cosmological Defects offers a sweeping, in-depth exploration into the relics of the early universe, charting a course from the primordial chaos of the Big Bang to the intricate tapestry of modern cosmological research. This definitive volume begins with an accessible introduction to cosmological defects and the dramatic phase transitions that set the stage for their formation (Chapter 1–2) and then delves into the mechanics of symmetry breaking and the influential Kibble-Zurek mechanism (Chapter 3). It builds a robust theoretical framework by systematically classifying topological defects—from the one-dimensional filaments of cosmic strings (Chapter 5) and the two-dimensional cosmic boundaries of domain walls (Chapter 6) to the point-like magnetic monopoles (Chapter 7), and extending further into the realm of complex, unstable defects such as textures and skyrmions (Chapter 8). The journey continues as the book ventures "beyond standard defects" to explore the role of extra dimensions and the emergence of hybrid structures from multiple symmetry breakings (Chapter 9), while also showcasing the latest astronomical methods that link theory with observation (Chapter 10). In a broader cosmological context, it examines how these defects might have seeded large-scale structures and acted as catalysts in cosmic evolution (Chapter 11). The final chapters bring the discussion full circle—synthesizing theory and observation into a comprehensive conclusion (Chapter 12) and providing a critical analysis of the seminal references that have shaped the field (Chapter 13). Drawing upon a wealth of highly credible, peer-reviewed research—from seminal works by Kibble, Linde, and Vilenkin to transformative observational studies by the Planck Collaboration—Cosmological Defects is an essential resource for PhD-level scholars and researchers. It not only presents complex ideas in a clear and engaging manner but also offers deep insights into the current challenges and future directions of cosmology, ensuring that readers gain a thorough understanding of both the historical context and cutting-edge developments in the study of the universe’s most enigmatic structures.

"Dream of the Red Mansions," the seminal novel penned by the Qing Dynasty writer Cao Xueqin, presents a vivid tapestry of life within the aristocratic society of China's feudal era. Despite the constraint of word count, I shall endeavor to encapsulate its translation into English and offer a concise portrayal of its iconic imagery. The title "Dream of the Red Mansions" itself, translated as "A Dream of Red Mansions" by Yang Xianyi and Gladys Yang, alludes to the grandeur and opulence of the Jia clan's mansion, where the story unfolds. In Western cultures, "red" might connote blood or violence, whereas in the Chinese context, it symbolizes prosperity and status. This translation, though faithful to the original, carries a nuanced cultural difference that foreign readers may interpret through the lens of their own experiences. The novel revolves around the Jia, Shi, Wang, and Xue families, portraying their rise and fall amidst the complexities of power, wealth, and love. The protagonist, Jia Baoyu, an enigmatic young man endowed with a "Jade of Spiritual Enlightenment," finds himself at the center of a web of relationships, particularly his unrequited love for Lin Daiyu, a delicate and sensitive beauty, and his arranged marriage to Xue Baochai, a more practical and conformist figure. The translation captures the intricate emotional landscape of these characters, rendering their intricate feelings and motivations in a manner that resonates with English-speaking audiences. The beauty of Lin Daiyu, for instance, is described in poetic terms that evoke her ethereal grace and fragile fragility, while Xue Baochai's character is portrayed as a bastion of traditional virtues, embodying the expectations of feudal society. The novel's imagery extends beyond the personal lives of its protagonists, encompassing the intricate architecture of the mansions, the rich tapestry of cultural practices, and the profound philosophy embedded in its poetry and prose. The "Red Mansions" themselves become a metaphor for the fleeting nature of wealth and power, serving as a backdrop for the play of human emotions and desires. In translation, the novel's rich cultural heritage and nuanced language pose significant challenges. Yet, the translators have striven to preserve the essence of the original work while adapting it to suit the sensibilities of English readers. Through their efforts, "Dream of the Red Mansions" transcends linguistic and cultural barriers, offering a window into the vibrant world of China's feudal aristocracy and the human drama that unfolded within its confines.

My mother was a hotel room manager in her youth. One day, she found a used condom in the trash can of a hotel room. She had an outrageous idea and used the seminal fluid inside the condom to conceive a child. Later, she became pregnant, and that’s how I was born. And my biological father was a super wealthy man!
