Presidential Takedown

Science & Nature

An explosive behind-the-scenes look at Donald Trump's final months in office and how the COVID crisis response was a carefully crafted plan to ruin him.In January 2020, Donald Trump was on the fast track to an easy re-election. While his first two years had been stymied by House Speaker Paul Ryan, Senate Majority Leader Mitch McConnell, and the Democrats, his third year had been one of remarkable success. The United States had low unemployment and was making strides across the globe. The president's rallies were well-attended, and he was being projected to win four hundred electoral votes and about forty-five states. Then came COVID-19.Dr. Paul Elias Alexander, former Senior Advisor to COVID Pandemic policy in the US government for President Trump and former COVID Pandemic evidence-synthesis advisor to WHO-PAHO, was on the frontlines to watch how Trump's world, and his reelection hopes, slowly collapsed leading up to November 2020—due to the CDC, NIH, and WHO conspiring to overthrow him with the worst response possible to the COVID crisis.Supported by emails and documents, career epidemiologist Alexander and New York Times-bestselling author Kent Heckenlively, JD, will not only show proof of a presidential takedown, but also of the personal vendetta of the CDC and HHS against Alexander himself. From unnecessary lockdowns, school closures, and mask mandates to the dismissal of effective treatments like hydroxychloroquine, ivermectin, and vitamin D and even threats against President Trump and his family, Presidential Takedown: How Anthony Fauci, the CDC, NIH, and the WHO Conspired to Overthrow President Trump is the inside story of what really happened from those first COVID-19 reports to President Trump's "loss" in November.

Vidyarthiyon Ke Liye Vigyan

Science & Nature

इस पुस्तक में विज्ञान के जो आलेख सम्मिलित किए गए हैं, उन्हें मोटे तौर पर दो हिस्सों में बाँटा जा सकता है- कुछ आलेख ऐतिहासिक महत्त्व के हैं तो अन्य विज्ञान के महत्त्वपूर्ण मौलिक तथ्यों की व्याख्या करने वाले। दोनों प्रकार के आलेखों के लिए जन सामान्य की भाषा रखी गई है, साथ ही यह भी खयाल रखा गया है कि बिना तकनीकी और वैज्ञानिक तथ्यों पर समझौता किए एवं बगैर गणितीय समीकरणों में उलझाए, पाठकों तक बातें सरल तरीके से संप्रेषित की जा सकें। यही वह बिंदु है, जो इस पुस्तक की सफलता और उपयोगिता को निर्धारित करेगा। इनमें से ज्यादातर आलेख विभिन्न इंटरनेट पत्रिकाओं में प्रकाशित हुए हैं, जो कुछ हद तक इनकी प्रामाणिकता का विश्वास दिलाते हैं।

Mondi Paralleli

Science & Nature

Satelliti, rivelatori di onde gravitazionali, telescopi a raggi x e supercalcolatori ci forniscono continuamente dati sulla natura dell'universo, sulla sua età, la sua composizione e, soprattutto, il suo futuro e la sua fine. "Mondi paralleli" indaga a sua volta i misteri del cosmo in un viaggio che, partendo dal Big Bang e passando per le teorie che postulano l'esistenza di universi paralleli al nostro, giunge fino al Big Freeze, il grande gelo che immergerà ogni cosa nel freddo e nell'oscurità totali. Ma sarà davvero la fine di tutto? Oppure, tra miliardi di anni, una civiltà avanzata sarà in grado di sfruttare le leggi della fisica per dirigersi verso un universo più ospitale, o magari per tornare indietro nel tempo, in un'era in cui sia possibile ricominciare?

Ak totiž chceme pochopiť náš svet, nemusíme cestovať na nové miesta – musíme sa pozerať novými očami. „Vnímať svet inými zmyslami znamená nájsť nádheru v známom a posvätnosť v každodennom.“ Ed Yong

Unruly Complexity

Science & Nature

Ambitiously identifying fresh issues in the study of complex systems, Peter J. Taylor, in a model of interdisciplinary exploration, makes these concerns accessible to scholars in the fields of ecology, environmental science, and science studies. Unruly Complexity explores concepts used to deal with complexity in three realms: ecology and socio-environmental change; the collective constitution of knowledge; and the interpretations of science as they influence subsequent research.For each realm Taylor shows that unruly complexity-situations that lack definite boundaries, where what goes on “outside” continually restructures what is “inside,” and where diverse processes come together to produce change-should not be suppressed by partitioning complexity into well-bounded systems that can be studied or managed from an outside vantage point. Using case studies from Australia, North America, and Africa, he encourages readers to be troubled by conventional boundaries-especially between science and the interpretation of science-and to reflect more self-consciously on the conceptual and practical choices researchers make.

Zabójstwo Narutowicza

Science & Nature

W stulecie zabójstwa pierwszego Prezydenta RP Gabriela Narutowicza przedstawiamy zbrodnię z grudnia 1922 oraz jej tło polityczne i społeczne – opowiedziane głosami uczestników i świadków wydarzeń. To historia nienawiści i nacjonalizmu prowadzących do tragedii, która zmieniła losy II Rzeczpospolitej.Czuć było, że się zanosi na jakieś wielkie, nieprzewidziane wypadki. Prasa obozu prawicowego wyraźnie podburzała, przedstawiając wybór Narutowicza jako triumf żydostwa i nieszczęście dla Polski. Tłumy zaczęły szaleć, wygrażając każdemu, kto głosował za Narutowiczem.Wincenty WitosSto lat temu Polska przyjęła cios, po którym nie zdołała finalnie wrócić do normalnego, zrównoważonego życia. Nacjonalizm wyniesiony do ponadczasowego absolutu, popychający zbrodniczą rękę, zniszczył niemal w zarodku kraj podnoszący się z niebytu – do państwowości, która mogła mieć cywilizowaną postać.Z wprowadzenia Zbigniewa Gluzy

A Well-Tempered Mind

Science & Nature

Peter Perret, conductor of the Winston-Salem Symphony for more than 25 years, wondered if placing a woodwind quintet in a poorly performing elementary school might help students academically. He decided to try, and the result was an eye-brow raising jump in the children’s test scores—and this book.Perret describes an innovative program for first-through third-graders at two elementary schools in Winston-Salem and a journey of discovery into the brain for him. The quintet taught the children to listen to music, detect the roles of the instruments, discern how music is constructed, and even compose their own music, all the while integrating the lessons into the children’s regular courses. Providing a mix of classroom vignettes, music theory, and findings in one of the newest areas of brain research, Perret shows how the Bolton program gave life to a host of tantalizing questions: Does music physically change the brain? Is music a primary language of the brain? Does music affect any cognitive abilities needed for reading and math? Can music help kids with short attention spans, dyslexia, and other learning difficulties? How did the musicians in the classroom contribute to the children’s academic improvement? A charming, inspiring reading experience, A Well-Tempered Mind describes the program in detail and offers valuable advice to parents, educators, and would-be teaching artists for designing music program approaches to suit their means and situations.

Il faut tuer les robots

Les faits paranormaux sont plus que jamais à l’ordre du jour. Spiritisme, chiromancie, cartomancie, songes, télépathie, médiumnité... nos contemporains s’efforcent, par ces voies et bien d’autres, de crever la carapace de mystère qui recouvre notre destin futur et notre vie présente. Parallèlement, bien des êtres réels ou présumés tels, bien des circonstances apparemment inexplicables, bien des pouvoirs étranges — guérisseurs, sorciers — sollicitent notre esprit intrigué. C’est cet ensemble de phénomènes qu’expose et étudie la collection « Bilan du mystère ». Son titre même en dit le but et l’esprit. Il ne s’agit pas d’accumuler, sans contrôle, anecdotes sur anecdotes pour amuser, dit-on, ou duper le lecteur. Il s’agit de dire, une bonne fois, ce qui en tous ces phénomènes est à retenir ou à rejeter, dans l’état actuel des observations scientifiques, en dehors de tout parti-pris, qu’il soit de crédulité ou d’incrédulité, de préciser ce qui est élucidé ou ne l’est pas encore, si tant est qu’il le soit jamais. Il s’agit donc bien d’un bilan, et d’un bilan sérieusement objectif. Pour l’établir nous avons fait appel à des connaisseurs autorisés des matières traitées, et qui y ont appliqué, avec une entière liberté d’esprit, information étendue et expérimentation directe. Ils le feront en langage clair, accessible à tous.
