Desde los clásicos trileros hasta los estafadores de criptomonedas, esta es la apasionante historia de los charlatanes y de por qué caemos una y otra vez en sus trampas.Durante siglos, los charlatanes han vivido de engañar a sus victimas. Hoy, la charlataneria es mas global y lucrativa que nunca. Gracias al poder de la tecnologia, los embaucadores de nuestra epoca han tejido una red de fraudes a una escala sin precedentes.En Charlatanes, el escritor y columnista especializado en asuntos internacionales Moises Naim y el periodista y politologo Quico Toro investigan como los nuevos timadores nos engañan con las mismas tecnicas que se utilizaban en el lejano Oeste: se ganan nuestra confianza, nos hacen creer que son los mayores valedores de nuestros sueños y luego nos explotan para su propio beneficio. En cierto modo, nada ha cambiado excepto una cosa: estos charlatanes son ahora digitales, virales y globales. Sean tanto gurus de la salud que promueven sus productos pseudocientificos como politicos que ocupan los puestos de mayor relevancia del escenario global, los timadores modernos acumulan audiencias de una punta a otra del planeta gracias a internet y las redes sociales, sirviendose de un conjunto de estrategias comunes y actuando con suma rapidez, mientras nuestras lentas instituciones luchan por responder.Repleto de ideas sobre como no caer en todo tipo de estafas ni en la charlataneria populista, este libro es un viaje revelador a traves del engaño descarado y la brutal victimizacion que se encuentran en el corazon de esta nueva lacra mundial.La critica ha dicho:El mundo siempre ha estado lleno de estafadores y timadores. Pero, ¿alguna vez te has preguntado por que somos tan vulnerables a sus trucos? ¿Y por que parecemos particularmente susceptibles a ellos en nuestros dias? Moises Naim y Quico Toro han escrito un libro fascinante que narra la historia, nos da explicaciones e incluso ofrece algunas ideas sobre que hacer con estos charlatanes. Fareed Zakaria Vivimos en una era de mentirosos, farsantes, timadores y charlatanes. Moises Naim y Quico Toro explican como ha ocurrido esto y lo que significa, con una prosa elocuente, urgente. Anne Applebaum Un analisis mordaz sobre los engaños y sobre por que caemos en ellos.Library Journal Los autores demuestran como cualquiera de nosotros puede caer facilmente en la trampa, porque lo que mejor saben hacer los charlatanes es devolvernos el reflejo de nuestros sueños. Frente a un arsenal de tecnologias explotadoras, comprender nuestras vulnerabilidades es el mejor escudo.Kirkus

Un prodigioso viaje a la época en que la ciencia y la alquimia movían juntas el mundo.En 1543, Nicolás Copérnico declaró que la Tierra giraba alrededor del Sol, revolucionando siglos de presunción escolastica. Se vislumbraba una nueva era, guiada por la observacion, la tecnologia y la logica.Pero los presagios y los elixires no desaparecieron de manera instantanea de los laboratorios. Durante mucho tiempo, aun se podian encontrar amuletos y pociones entre relucientes instrumentos de metal y tomos encuadernados en cuero. La linea entre lo natural y lo sobrenatural seguia siendo porosa e indefinida.Desde el gelido observatorio danes de Tycho Brahe hasta el taller humeante y sulfuroso de John Dee, la historiadora Violet Moller nos traslada a los albores de la ciencia europea para revelarnos un deslumbrante mundo olvidado, donde todo conocimiento, por arcano que fuera, podia buscarse con buena fe.La critica ha dicho:En su lucido relato de esta era transformadora, la historiadora y podcaster Violet Moller muestra como las dos corrientes por un lado la practica y por otro la hermetica y magica interactuaron y se informaron mutuamente.New Statesman Un analisis rico y atractivo sobre donde se produjo la actividad cientifica temprana y el contexto en el que florecio... Las vividas descripciones de Moller de laboratorios llenos de humo y talleres bulliciosos son estimulantes. Abundan los pasajes encantadores... El lector se sumerge en el mundo de la revolucion cientifica del siglo XVI.The Irish Times Un entretenido analisis de las instalaciones utilizadas por los cientificos de los siglos XV y XVI... El cariño de Moller por los personajes, a menudo caoticos pero inspiradores, es palpable. Para ella, representan un legado de audacia interdisciplinaria, una disposicion a traspasar fronteras geograficas e intelectuales, asi como a fusionar teoria y practica. Los cientificos de la actualidad, confinados en sus campos, a menudo limitados, harian bien en tener presentes sus esfuerzos.The Wall Street JournalViolet Moller capta algo vital. Los academicos del norte, en efecto, construyeron nuevas comunidades de investigacion, cuyos miembros se irritaban e inspiraban mutuamente. Las lineas de comunicacion eran fragiles, pero vibraban con mensajes impactantes... Tras las fachadas de las casas de comerciantes, en sotanos y aticos, en las torres y terrazas construidas para Guillermo IV y Tycho, se abrian nuevos caminos hacia la imponente puerta del palacio mas grande de todos, el de la propia Naturaleza.The Times Literary Supplement

Una obra puede leerse tanto como introducción a la astronomía extragaláctica como una meditación sobre la ciencia como empresa humana.Islas del universo no es un libro de astronomía convencional. Es, mas bien, el relato apasionado y lucido de una aventura cientifica: la que nos ha permitido descubrir que habitamos un rincon minusculo de un cosmos colmado de galaxias, estrellas y misterios aun sin resolver. Gaspar Galaz, astronomo y divulgador, recorre en estas paginas la historia de como fuimos comprendiendo el universo extragalactico, desde los rudimentarios telescopios de Galileo hasta los colosos opticos del siglo XXI, instalados bajo los cielos privilegiados de Chile.Al mismo tiempo, este libro es tambien una meditacion sobre el conocimiento, el asombro y la humanidad detras de la ciencia. A traves de un lenguaje claro y narrativo, Galaz no solo explica conceptos complejos con sencillez y rigor, sino que rescata los errores, intuiciones y pasiones de quienes, como el, han dedicado su vida a observar lo inmenso. Un homenaje a las galaxias -verdaderas islas en el universo- y tambien a los hombres y mujeres que, desde sus propias islas interiores, se han atrevido a explorar los confines del espacio.

The Essential George Boole: Logic, Love and Legacyis a captivating portrait of a brilliant mind and the family that shaped him. George Boole, a largely self-taught genius, as a youth mastered multiple languages and scientific disciplines and later developed symbolic logic and what is now called Boolean algebra, the foundation of modern computing. He rose from poverty to become a respected professor at Queens College Cork, now University College Cork. It is believed by some that he inspired Arthur Conan Doyles creation of Professor Moriarty, the arch-enemy of Sherlock Holmes. But Booles story isnt just about logical and mathematical prowess. He was married to a remarkable woman, educationalist Mary Everest. Their five remarkable daughters and subsequent generations carried on a legacy of brilliance, breaking barriers in science, medicine and literature. Geoffrey Hinton, George Booles great great-grandson, is the 2024 Nobel Laureate in Physics. Booles story as one of the founders of the digital age is one of perseverance, love and ideas that changed virtually everything.

After working as a botanist and natural historian for more than 25 years, walking the countryside had almost imperceptibly turned into a disheartening endeavour for Pete Stroh. He found himself resting at viewpoints and contemplating how much better it would be if a pasture had not been drenched with herbicide, if a woodland had not been planted up with regimented lines of conifer crops, if an arable field could every so often not be ploughed right up to the bloody roots of the hedgerowSo he decided that in writing this book, he would wander within the boundaries of the parish where he lives, record weekly what he actually saw, and restrict grumblings to a minimum, to observe rather than judge. This, he writes, took a bit of getting used to but proved ultimately to be a liberating and unexpected experience.The result is this uplifting and positive book showing the surprising abundance of nature, given half a chance.

Many people as they get older have to face leaving a village or town they have loved, a place redolent with memories and connections, to relocate somewhere more as they say manageable. It is different for everyone, and not always easy, for our ghosts go with us.But everything connects with everything else. There is no such thing as a new beginning. Such a move need not be a matter for repining and regret, but a new adventure.This book records just that journey, of having to learn that new place to which Time is bringing you and populate it with its own stock of private memories.Charles Moseley writes about his move from a fenland village to the nearby historic little city of Ely and breathes life into the history, natural world and people who have made his new home what it is today.

Gods Providential Work in Creation Before Life Began God has been present and active in creation from the moment he created it ex nihilo. Few Christians would question this claim, but its implications for ongoing theology and science dialogues have not been fully explored.In this pathbreaking and field-advancing work, Ross Hastings brings his expertise in both scientific and theological disciplines to bear on the topic of divine providence in chemical evolution. Based on the latest research in the developing field of chemical evolution and the work of theological giants such as Karl Barth, Hastings shows how God may have been providentially and non-competitively at work in the process by which simple prebiotic molecules gave rise to the complex molecules in the first living organisms.In God and Molecules, Hastings provides cutting-edge theological engagement with the developing scientific field of chemical evolution, advances the discussion in theology and science with this new integrative work, and offers a holistic alternative for thinking about chemical evolution that overcomes the binary of theology versus science. God and Molecules pushes toward new frontiers in theology and science and casts a compelling, integrative, and ultimately healing vision for how God has been lovingly involved in the developmental process of the earliest life on earth.

Bringing Integrity to the Stories Numbers Tell When we tell stories with numbers, we depend on the field of statisticsbut how do we know that those stories are true? Almost everything in life is connected to data, and that data can help us make sense of truth in a world that feels increasingly challenging to navigate as Christians.But in a world where we are told to "do our own research," it can be nearly impossible to know whether were just gravitating toward stories that confirm our own untested biases, or whether were analyzing the data in a way that is illuminating truth.Exploring a range of contemporary topics, professor of statistics Jason Wilson shows both non-experts and experts alike that statistics has something to say when it relates to the polarizing issues that we face today. Exploring topics such as gambling, Covid, and media bias, Wilson shows that the ways we collect, organize, analyze, and interpret data have something to say in conversation with the Christian faith.In Statistics and Faith, youll find examinations of contemporary issues using statistical concepts, tools, and theories; case studies from history that show how statistics can be used in ways that are helpful or harmful; application chapters based on over fifteen years of research; and reflection questions to help you explore how to do statistics with integrity. This book is ideal for professors seeking to help students explore the history and application of statistics from a Christian worldview as well as for Christians who are curious about how we understand truth through numbers. It serves as an ideal supplementary text for statistics courses and other disciplines that incorporate statistical methods, and it offers an insightful perspective on how statistics in conversation with Christian faith can speak to todays polarizing issues, empowering readers to discern truth through data in a noisy world.

Illness is not simply a matter of biology. Our thoughts, conscious or otherwise, can make us feel pain or become unwell. If you experienced side effects from your Covid vaccine, the chances are that these were caused by your belief that you would experience them. When a nurse tells you this is going to hurt, it generally does - but perhaps it shouldnt.In this revelatory study, neuroscientist Helen Pilcher explores the hidden impact of the nocebo effect - the placebos evil twin. Medical studies have proven the nocebo effect to cause pain, nausea, paralysis, seizures, and even blindness. The nocebo effect impacts how we grow sick and grow old, explains why people who dont have food allergies have dietary intolerances, and why adults and teenagers are equally susceptible to catching tics through social media. From Havana Syndrome to hex deaths, chronic pain and mystery illnesses, this book explains what happens when illness, psychology and society meet - and shows us what we can do to become less ill and more well.

Every leader comes to power promising growth: think back to the campaigns of Boris, Truss, Sunak, Starmer, Trump. Yet real-term income hasnt improved in the UK since 2008. Across the West, growth has stagnated for well over a decade, leading to cost of living crises, political instability and rising social tensions.Is real economic growth still possible? And with the climate emergency accelerating beyond repair, should we still be pushing for it?In Icarus Economics, acclaimed economist John Rapley argues that the problem of growth is inherently tied up with the climate crisis. We often assume that poor countries will bear the brunt of climate change, pandemics, and other exogenous shocks, but this book argues the opposite: western societies have more wealth and capital to lose and are less inherently resilient. In this book, he shows us how rich countries can grow their own economies by helping poor countries to decarbonise - and in the process, mitigate the effects of climate change.
