Mescaline, LSD, and psilocybin mushrooms. There’s been a lot of discussion in the medical world lately about the potential benefits of these and other drugs for certain medical conditions, such as anxiety and depression. As we consider the place of psychedelics in the future, we can draw insight and guidance from the history of how psychedelics have been described, sought after, applied, and prohibited over the centuries. Erika Dyck, professor of history at the University of Saskatchewan, introduces you to the world of hallucinogens.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

In A Mind for Numbers, Dr. Oakley lets us in on the secrets to learning effectively - secrets that even dedicated and successful students wish they’d known earlier. Contrary to popular belief, math requires creative, as well as analytical, thinking. Most people think that there’s only one way to do a problem, when in actuality, there are often a number of different solutions - you just need the creativity to see them.

An eminent scientist and pioneer in the discovery of retroviruses challenges the widely accepted belief that HIV is the cause of AIDS. Duesberg argues that HIV is merely a harmless passenger virus that does not cause AIDS. Sure to spark intense debate, this provocative book offers an original and incisive critique of the rise and fall of HIV.

Does time exist? What is infinity? Why do mirrors reverse left and right but not up and down? In this scintillating collection, Holt explores the human mind, the cosmos, and the thinkers who’ve tried to encompass the latter with the former. With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot.

Geneticist Adam Rutherford and mathematician Hannah Fry guide listeners through time and space, through our bodies and brains, showing how emotions shape our view of reality, how our minds tell us lies, and why a mostly bald and curious ape decided to begin poking at the fabric of the universe.

From the simple to the intricate and the audacious to the absurd, Adam Kucharski reveals the long and tangled history between betting and science and explains why gambling continues to generate insights into luck and decision making today. Covering exploits and ideas from across the globe, he meets the teams behind hedge funds that capitalize on inaccurate sports betting odds and explains how PhD-level pundits are using methods originally developed for the US nuclear program to predict sports results.

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

We at Abstract Thoughts aim to bring more awareness to the world about the safe use of psychedelic mushrooms, the benefits as well as the drawbacks, that people should think about before making a decision to "trip". The whole idea is just to spread awareness and educate the masses, from beginner growers to our more experienced growers too. Psilocybin Mushroom: A Safe Trip, is a one-stop listen for psychedelic enthusiasts all over the world who are serious about gaining a complete understanding of the magic that is mushrooms.

From Leonardo Da Vinci to John Dee and Comenius, from George Eliot to Oliver Sacks and Susan Sontag, polymaths have moved the frontiers of knowledge in countless ways. But history can be unkind to scholars with such encyclopaedic interests. All too often these individuals are remembered for just one part of their valuable achievements. In this engaging, erudite account, renowned cultural historian Peter Burke argues for a more rounded view.

One of the great insights of science is that the universe has an underlying order. The supreme goal of physicists is to understand this order through laws that describe the behavior of the most basic particles and the forces between them. For centuries, we have searched for these laws by studying the results of experiments. Since the 1970s, however, experiments at the world's most powerful atom-smashers have offered few new clues. So some of the world's leading physicists have looked to a different source of insight: modern mathematics.

Dirty Electricity tells the story of Dr. Samuel Milham, the scientist who first alerted the world about the frightening link between occupational exposure to electromagnetic fields and human disease. Milham takes listeners through his early years and education, following the twisting path that led to his discovery that most of the 20th-century diseases of civilization, including cancer, cardiovascular disease, diabetes, and suicide, are caused by electromagnetic field exposure. 

This 10-part history of mathematics reveals the personalities behind the calculations: the passions and rivalries of mathematicians struggling to get their ideas heard. Professor Marcus du Sautoy shows how these masters of abstraction find a role in the real world and proves that mathematics is the driving force behind modern science.

Vous connaissez tous cet objet iconique, l'avez très certainement déjà manipulé. Le Rubik's Cube a suscité l'engouement de plus d'un milliard de personnes depuis 1974. Mais d'où vient-il ? Et comment expliquer un tel succès ? Son créateur, adepte des puzzles et des casse-têtes en tous genres, retrace la folle aventure de son invention. Il livre une véritable réflexion sur les mécanismes du jeu, les avantages de la symétrie, les vertus de la concentration, et nous montre que le Rubik's Cube est bien plus qu'un simple passe-temps.

It was Christmas Eve 1968. And the astronauts of Apollo 8 - Commander Frank Borman, Jim Lovell, and Bill Anders - were participants in a mission that took them faster (24,000 mph) and farther from the Earth (240,000 miles) than any human had ever traveled. Apollo 8 was the mission that broke humanity's absolute bond to the Earth: it was the first manned vehicle to leave the Earth's orbit. Confined within a tiny spaceship, the astronauts were aided in their journey by a computer less powerful than one of today's handheld calculators.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.

The foundations of modern knowledge - philosophy, math, astronomy, geography - were laid by the Greeks, whose ideas were written on scrolls and stored in libraries across the Mediterranean and beyond. But as the vast Roman Empire disintegrated, so did appreciation of these precious texts. Christianity cast a shadow over so-called pagan thought, books were burned, and the library of Alexandria, the greatest repository of classical knowledge, was destroyed. Yet some texts did survive and The Map of Knowledge explores the role played by seven cities around the Mediterranean....

Saint-Simon fut souvent considéré comme l'un des plus grands écrivains de la langue française. Il fut contemporain de Louis XIV et ses Mémoires, écrites en vingt volumes, constituent un témoignage essentiel de ce que fut cette époque et nous offrent une plongée fascinante dans l'univers du Roi Soleil, le plus célèbre de tous les rois. Les pages qui suivent sont issues d'une sélection effectuée au cœur de ces mémoires dont la teneur résume, sans avoir besoin de lire l'ensemble de l'œuvre, l'atmosphère qui régnait à la Cour du Roi.

In 1918, a world war raged, and a lethal strain of influenza circled the globe. In the midst of all this death, a bizarre disease appeared in Europe. Eventually known as encephalitis lethargica, or sleeping sickness, it spread worldwide, leaving millions dead or locked in institutions. Then, in 1927, it disappeared as suddenly as it had arrived. Asleep, set in 1920s and '30s New York, follows a group of neurologists through hospitals and asylums as they try to solve this epidemic and treat its victims - who learned the worst fate was not dying of it, but surviving it.

Durant des siècles, le loup-garou a hanté l'âme des hommes. Déjà connu des grecs et des romains, le loup-garou connaît son apogée au XVIe et XVIIe siècles. Nous le verrons bientôt déguerpir, chassé des consciences par les lumières de la raison. Mais avant, poursuivons-le, accompagné d'historiens, d'ethnologues et d'analystes... Car au fond comprendre le loup-garou, c'est comprendre l'homme.
