In 1991, eight "biospherians" were sealed inside a three-acre glass terrarium in the Arizona desert. Biosphere 2 contained a rainforest, an ocean, and a savannah. It was meant to prove that humans could colonize Mars. Instead, it proved how little we understand Earth. Oxygen levels plummeted, crops failed, the crew split into warring factions, and crazy ants exterminated the other insects."The Glass World" documents the most ambitious ecological experiment in history. It details the scientific hubris, the psychological strain of isolation, and the humbling realization that we cannot engineer a replacement for nature. A crucial read for the climate change era, showing that "Planet B" is much harder to build than we think.

On August 21, 1986, the farmers around Lake Nyos in Cameroon went to sleep in a silent valley. By morning, every living thing1,746 people, 3,500 livestock, even the flieswas dead. There was no fire, no flood, and no violence. The killer was the lake itself.This book investigates the terrifying phenomenon of a limnic eruption, where a lake "burps" a massive cloud of carbon dioxide, displacing oxygen and drowning a valley in invisible gas. It follows the scientific detective story to understand the event, the race to degas the lake before it strikes again, and the geological ticking time bombs hiding in crater lakes around the world. A gripping look at how the earth breathes, and sometimes, holds its breath too long.

In 1953, a young man named Henry Molaison underwent experimental surgery to cure his epilepsy. The doctor removed his hippocampus. The seizures stopped, but so did time. For the rest of his life, Henry lived in a permanent present, his memory resetting every 30 seconds. He could meet you, shake your hand, and forget you before you sat down.Known to science as "Patient H.M.," Henry became the most studied human brain in history. This book tells his poignant life story and how his tragedy proved that memory is not a single filing cabinet, but a complex network of systems. He couldnt remember doing a puzzle, yet his hands learned how to solve itproving that the body remembers even when the mind forgets.

While Americans looked up to the moon, the Soviets looked down. In the frozen wastes of the Kola Peninsula, they spent 20 years drilling the deepest hole in history. The goal was the mantle. They reached 12,262 meters (7.6 miles) before the laws of physics stopped them.This book documents the engineering marvel of the Kola Superdeep Borehole. It debunks the urban legend that they "heard the screams of hell," but the scientific reality was stranger: At that depth, rock behaves like plastic, and water exists where it shouldnt. It is a story of extreme engineering, Cold War rivalry, and the crushing heat that protects the Earths secrets.

Close your eyes and touch your nose. You can do it because of proprioceptionthe bodys internal sense of position. But at age 19, Ian Waterman lost this sense completely due to a rare viral infection. He became a "rag doll," unable to stand, sit, or even hold a cup, despite having healthy muscles. He had lost his body.In the tradition of Oliver Sacks, this book tells the inspiring story of how Ian taught himself to move again by using his eyes to replace his nerves. He has to consciously watch every limb to move it. It is a profound exploration of the "sixth sense" that grounds us in reality, and what happens when the connection between mind and flesh is severed.

THIS book contains twelve stories of great inventions, with a concluding chapter on famous inventors of today. Each of the inventions described has added to the comforts and joys of the world. Each of these inventions has brought about new industries in which many men and women have found employment. These stories, therefore, offer an easy approach to an understanding of the origin of certain parts of our civilization, and of the rise of important industries.The story of each invention is interwoven with that of the life of its inventor. The lives of inventors furnish materials of the highest educative value. These materials are not only interesting, but they convey their own vivid lessons on how big things are brought about, and on the traits of mind and heart which make for success.It is hoped that this book will set its readers to thinking how the conveniences of life have been obtained, and how progress has been made in the industrial world. While appealing to their interest in inventions and in men who accomplish great things, may it also bring them into contact with ideas which will grip their hearts, fire the imagination, and mold their ideals into worthier forms.

This book is the result of many years of contact with embalmers in training and in practice. We have included in this work a crystallization of essential information without which, the embalmer must be poorly equipped to carry out the many duties incident to his calling in a manner satisfactory to his patrons and to himself.Having been thrown in contact with the many problems surrounding the education of the embalmer, the authors have gained many ideas as to just how to place the information before the embalmer so that the result will be reflected in an increased capacity for good work on the part of the individual embalmer.In prescribing information for the embalmer in this manner, we know clearly just what is to be expected from the application of the sciences herein described, and wish for the novitiate and practitioner the same enthusiasm for actual knowledge that has helped us thus far in arranging the information.In Part One, we have chronicled, from the word of historians and men of the present day, a condensed, yet complete exposition of the funeral customs relating to the care of the dead, giving our readers a better understanding of present methods by reason.

Déjà Vu é uma história que já existia em minha mente há muitos anos; um dia, simplesmente a transpassei para as páginas. Esta é a curta saga de Ariel, uma adolescente de dezesseis anos que fica desol

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.
