Uno de los mayores retos a los que se enfrentan los estudiantes en su transición a la vida universitaria es superar vacíos en los fundamentos del Precálculo. Con explicaciones claras y práctica guiada, Un curso de Precalculo ofrece una solucion integral para fortalecer las bases de cada alumno. Esta obra se compone de dos libros: La teoria, que es el material guia, y La practica, que es el material para desarrollar los ejercicios. En ellos se abordan contenidos esenciales de algebra, ecuaciones y desigualdades, funciones y trigonometria, con ejemplos conectados y practica constante. En el aula y en el tiempo de estudio independiente, esta conexion entre teoria y aplicacion permite que el estudiante tenga un aprendizaje dinamico y eficaz, especialmente pensado para personas que provienen de distintos contextos escolares y buscan adaptarse con exito al entorno academico universitario.

El propósito del documento es compartir las experiencias personales de la autora, Silvia Linares Rodríguez, en su proceso de autodescubrimiento y lucha espiritual respecto a su orientación sexual como mujer catolica practicante con sentimientos homosexuales. A traves de su relato autobiografico, busca ofrecer reflexiones, aprendizajes y herramientas espirituales que puedan ayudar a otras personas que se encuentren en situaciones similares, promoviendo un camino de purificacion y santificacion del alma desde la perspectiva de la fe catolica. Ademas, el texto aborda temas relacionados con la homosexualidad desde un enfoque religioso, psicologico y espiritual, con el objetivo de proporcionar orientacion y apoyo a quienes enfrentan conflictos internos relacionados con su orientacion sexual.

Los intervalos de confianza para un parámetro poblacional son ampliamente revisados en la teoría estadística. En particular, los extremos del intervalo de confianza para la media de la distribución normal, estan en funcion de la varianza poblacional; sin embargo, en la mayoria de los casos de interes se desconoce este valor lo que imposibilita usar la formula con la distribucion normal. La alternativa natural es usar el estimador de la varianza, usando entonces la formula con la distribucion t de Student, teniendo un intervalo de confianza teoricamente exacto.Cuando la distribucion de probabilidad no es la normal, entonces para una muestra "suficientemente grande" el teorema central del limite, respalda la utilizacion de la misma formula usada para la normal, pero al aplicarla se usa el estimador de la varianza. Asi en los hechos al construir el intervalo de confianza, en estos casos, se tienen dos aproximaciones, una que es la aproximacion normal por el teorema central del limite y otra por el uso del estimador de la varianza en lugar de usar la varianza real.En este libro, en el capitulo tres, se presenta la construccion de los intervalos de confianza para la media de cuatro distribuciones no normales, la binomial, la Poisson, La uniforme continua y la exponencial, basandonos en el teorema central del limite; pero a diferencia de los intervalos usuales, se usa la varianza real, que es desconocida pero que depende del mismo parametro que la media y es calculable.

THE YEAR 6030: The Restored Order of Time, Space, and EnergyEverything you think you know about the world you live in is based on a taught model, not on the reality you have observed for yourself. The Year 6030 is a groundbreaking journey to the unshakable foundation of our existence. This book restores the collective amnesia of humanity by lifting the veil of the cosmic illusion.Why does our calendar consist of twelve irregular months? This work proves that we live in chronological chaos and advocates for the restoration of the natural 13-month calendar. Discover how the catastrophe of 1656 AM mechanically disrupted the world machine and slowed down the cosmic clock.From the stationary earth beneath the solid Firmament to the hidden powers of the ether-battery: this research combines historical sources with modern engineering. Learn why water always seeks its own level, how the sun warms us through induction, and why space travel masks the view of our enclosed garden."Measuring is knowing." Do you dare to set aside your learned filters and see the world as it truly is? Welcome to the rediscovery of reality.

Sou conhecido no mundo inteiro, mas minha fama nem sempre é das melhores. Na verdade, muita gente se intimida comigo. Por isso decidi escrever minha biografia: para que me conheçam um pouco melhor e assim, quem sabe, acabem gostando um pouco mais de mim. O fato e que algumas coisas sobre mim nem eu mesmo sei, e talvez esta seja a oportunidade de voce me ajudar a entende-las.Assim começa a autobiografia mais improvavel da matematica: narrada pelo proprio numero Pi, esse personagem irracional, infinito e por vezes incompreendido. Ao longo destas paginas, o narrador nos conduz por sua trajetoria epica: das aproximaçes de Arquimedes aos metodos inovadores de Ramanujan, passando pelas descobertas de Liu Hui, o primeiro a dar ao numero a notaço decimal utilizada ate hoje: 3,14.Escrito pela matematica iraniana Mahsa Allahbakhshi e pelo divulgador cientifico chileno Andres Navas, com ilustraçes vibrantes da designer mexicana Verena Rodriguez, o livro da voz a um Pi aventureiro e curioso, que percorre a historia da humanidade em busca de respostas sobre si mesmo e seus enigmas. Nessas andanças, atravessa fronteiras e milenios e nos mostra como, desde a Antiguidade, diversos povos egipcios, babilonios, chineses e gregos se aproximaram de seu valor. Entre as figuras que marcaram sua jornada, Arquimedes surge como heroi fundador, seguido por outros matematicos que, com engenho e perseverança, buscaram compreender esse numero que nunca se deixa capturar por completo.Ao chegar a era moderna, Pi revela como o calculo diferencial, as series e os radianos ampliaram o conhecimento sobre suas casas decimais, enquanto a celebre quadratura do circulo mobilizou mentes brilhantes ate se provar impossivel. Em meio a curiosidades, anedotas, explicaçes teoricas e episodios historicos, o narrador mostra como cada tentativa de decifra-lo impulsionou novos avanços na matematica.Na terceira parte, o seculo xx, ha uma virada em sua historia: Ramanujan revoluciona os metodos de calculo; decadas mais tarde, a ferramenta do matematico indiano se soma ao poder dos supercomputadores, possibilitando o registro de trilhes de digitos de Pi. Num dos capitulos finais de sua autobiografia, escrito exclusivamente para a ediço brasileira, o narrador desembarca no Brasil para o Congresso Internacional de Matematica realizado em 2018 no Rio de Janeiro. E em So Paulo, numa especie de antessala do congresso, integrantes da Unio Matematica Internacional (IMU) aprovam a escolha de 14 de março como Dia Internacional da Matematica motivo de festa para o protagonista, ja que a data, pela formulaço usual nos Estados Unidos, remete a seus digitos mais conhecidos: 3,14.Em prosa leve e irreverente, com uma pitada de erudiço, Pi revela como se tornou um dos numeros mais fascinantes da historia.

"The Four Year War The conflict that shattered the myth of the peaceful ape" documents the Gombe Chimpanzee War (19741978). Before this event, scientists believed chimpanzees were peaceful vegetarians. Jane Goodall watched in horror as the Kasekela community systematically hunted down and annihilated the Kahama communityapes that had previously been their friends and family.Author Helen Wild describes the brutal tactics: kidnapping, gang attacks, and celebration after kills. The violence was so shocking that Goodall famously said she woke up at night seeing the images."The Four Year War" forces us to confront the darkness in our own DNA. It proves that war, territorialism, and calculated violence are not unique to humans, but deep-seated primate behaviors that predate civilization.

"The Dog in the Fox The experiment that replayed 10,000 years of evolution" details the most famous experiment in the history of genetics. In 1959, Soviet scientist Dmitry Belyaev started a secret farm in Siberia to domesticate silver foxes. His method was simple: He bred only the foxes that were least afraid of humans.Science writer Elena Furr describes the astonishing results. Within just a few generations, the aggressive foxes didnt just become friendly; they changed physically. They developed floppy ears, curly tails, and spotted coatstraits associated with dogs. Belyaev discovered "Domestication Syndrome," proving that selecting for behavior (tameness) accidentally drags along physical changes."The Dog in the Fox" is a window into our own past. It explains how the wolf became the dog and suggests that humans may have "self-domesticated" in the exact same way, trading aggression for cooperation and changing our own biology in the process.

"The Trash Cage How a cloud of junk could trap humanity on Earth forever" investigates the "Kessler Syndrome," a theoretical scenario proposed by NASA scientist Donald Kessler in 1978. It suggests that once the density of objects in low Earth orbit is high enough, collisions between objects could cause a cascade: one satellite hits another, creating thousands of shrapnel pieces, which hit other satellites, creating a chain reaction.Science writer David Junk describes the terrifying result: a shell of debris moving at 17,500 mph that destroys everything in orbit and makes leaving the planet impossible for centuries. We would be trapped under a ceiling of our own garbage, losing GPS, weather forecasting, and telecommunications."The Trash Cage" is an environmental wake-up call. It treats space not as an infinite void, but as a finite resource that we are polluting to the point of no return, threatening to end the Space Age before it has truly begun.

"The Atmospheric Assassin The inventor who accidentally poisoned the entire planet" tells the biography of Thomas Midgley Jr., often cited as the single organism that had the most destructive impact on the atmosphere in Earths history. A brilliant chemist for General Motors, Midgley solved the problem of engine "knocking" by adding lead to gasoline. Despite knowing it was toxic (he poisoned himself during demos), he pushed it into the global market.Author Oliver Haze recounts how Midgley later tried to solve the problem of dangerous refrigerants and invented Freon (CFCs)the very gas that tore a hole in the ozone layer. The book culminates in his tragic, ironic death: paralyzed by polio, he invented a pulley system to lift himself out of bed, which eventually entangled and strangled him."The Atmospheric Assassin" is a grim study of short-term solutions causing long-term catastrophes. It explores the hubris of industrial chemistry and the decades-long fight to remove lead from the environment.

"The Dangerous Zero The heretical number that the church tried to ban" tells the biography of a number. For centuries, the West relied on Roman numerals, a clumsy system that had no concept of "nothing." The idea of a void was terrifying to the medieval Church, which associated emptiness with the devil. Zero had to be imported from India and the Arab world, smuggled in by merchants like Fibonacci.Science writer Benjamin Scott traces the battle between the Abacists (conservatives) and the Algorists (innovators). The book explains how the acceptance of zero allowed for the birth of calculus, negative numbers, and modern physics. It is a story of how a mathematical concept clashed with theology."The Dangerous Zero" reveals that the most powerful number is the one that represents nothing. It shows how the acceptance of the void was the necessary first step for humanity to understand the infinite universe.

We live in a time in which global crises no longer occur sequentially, but overlap, reinforce one another and challenge our systems in constantly shifting constellations. In the midst of this dynamic, a new need for orientation is emerging not through simple answers, but through architectures that make complexity visible, keep uncertainty navigable and distribute responsibility. This framework proposes such an architecture. It unites epistemic, semantic and resilient integrity and shows how knowledge emerges, how it is shared and how it can be used responsibly. Geospatial AI & Critical Infrastructure describes not merely a technical field, but a space in which spatial intelligence, operational systems and societal responsibility are inseparably intertwined. A particular focus of this work also lies on offshore systems, Arctic operational environments and the responsible use of digital twins. The framework shows how AI agents can become reliable partners in sensitive domains not through maximal automation, but through transparent, robust and self reflective models. It reveals how many blind spots exist today and why epistemic integrity must become the foundation of modern world models, from BIM to digital twins to shadow pattern to EO supported systems. At the same time, it introduces a new profession: Epistemic Engineering the design of knowledge architectures that understand their own limits. With the Epistemic Maturity Model and the Epistemic Integrity Layer, structures emerge that make stability, transparency and resilience measurable. Many additional solution concepts, modules, geo AI scenario training, guidelines and much more await you in this framework. And with the Geo Resilience Compass, this architecture gains an instrument that provides orientation where uncertainty dominates. This work unfolds its strength not in individual chapters, but in the interplay of all its components. I warmly invite you to join me on this exciting and necessary journey.

A Neuralgia do Trigêmeo (NT) é considerada uma das dores mais intensas que um ser humano pode sentir, mas ainda é cercada por desinformação e diagnósticos equivocados. Desvendando a Neuralgia do Trig

"The book that defined how the world works."In The Mathematical Principles of Natural Philosophy, Isaac Newton didnt just explain how things move; he provided the mathematical proof for the mechanics of the entire universe. Moving beyond the speculative theories of his predecessors, Newton used rigorous geometric proofs to establish his Three Laws of Motion. From the falling of an apple to the orbits of the planets, he demonstrated that the same physical forces apply everywhere. This masterwork transformed the study of nature from a branch of philosophy into the modern discipline of physics, forever changing our understanding of space, time, and force.The Law of Universal Gravitation: Newtons most famous contribution within these pages is the derivation of the inverse-square law of gravity. He proved that every mass in the universe attracts every other mass, providing the first coherent explanation for why the moon orbits the Earth and why the planets remain in their paths around the sun.A Triumph of Mathematical Logic: Though Newton had developed calculus (which he called "fluxions"), he wrote the Principia using classical geometric proofs to ensure his contemporaries could follow his revolutionary logic. The result is a work of staggering intellectual density that remains the gold standard for scientific inquiry.Why It Is Essential: To own the Principia is to own the spark of the Scientific Revolution. It is the bridge between the ancient world and the space age, a testament to the power of the human mind to decode the hidden laws of nature.Own the foundation of modern science.
