When physician Adriane Fugh-Berman of Georgetown University School of Medicine in Washington, D.C., was asked to write a review article on interactions between herbs and warfarin, she said maybe. A clinician and expert on herb-drug interactions, Fugh-Berman thought the information could be useful to clinicians who prescribe warfarin as an anticoagulant.
Asbestos, climate change, 5G, coronavirus – the public is caught in a battle for the truth. Science is being manipulated and undermined to sway opinion and create doubt. What are the mechanisms behind it all?
Never has scientific knowledge seemed so vast, detailed and widely shared. And yet it appears to be increasingly challenged.
It’s no longer surprising to see private corporations put strategies in place to confuse public debate and paralyze political decision-making. Why did it take decades to classify tobacco as harmful? Why do people still deny human involvement in climate change? Overwhelmed by an excess of information, how can we, as citizens, sort out fact from fiction?
One by one, this film dismantles the machinations that aim to turn science against itself. With the help of declassified archives and testimonies from experts, lobbyists and politicians, this investigation plunges us into the science of doubt. Along with a team of experts, including philosophers, economists, cognitive scientists, politicians, and scholars, we explore concrete examples of how doubt can be sown, and try to understand the process.
Join myself and Applied Mathematics Professor Steven Strogatz, author of “Infinite Powers: How Calculus Reveals the Secrets of the Universe”, as we talk about the creative powers of math, as well as poetry and the writing process, and finding the connections between the two.
If you’ve never thought of math as beautiful or creative this episode just might change your mind. I hope you will love this conversation as much as I loved being a part of it!
Eat poorly, and your body will remember—and possibly pass the consequences onto your kids. In the past several years, mounting evidence has shown that sperm can take note of a father’s lifestyle decisions, and transfer this baggage to offspring. Today, in two complementary studies, scientists tell us how.
One of our greatest living scientists–and the winner of two Pulitzer Prizes for On Human Nature and The Ants–gives us a work of visionary importance that may be the crowning achievement of his career. In Consilience (a word that originally meant “jumping together”), Edward O. Wilson renews the Enlightenment’s search for a unified theory of knowledge in disciplines that range from physics to biology, the social sciences and the humanities.
Using the natural sciences as his model, Wilson forges dramatic links between fields. He explores the chemistry of the mind and the genetic bases of culture. He postulates the biological principles underlying works of art from cave-drawings to Lolita. Presenting the latest findings in prose of wonderful clarity and oratorical eloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions of Newton, Einstein, and Richard Feynman.
This book argues that the division of the brain into two hemispheres is essential to human existence, making possible incompatible versions of the world, with quite different priorities and values.
Most scientists long ago abandoned the attempt to understand why nature has so carefully segregated the hemispheres, or how to make coherent the large, and expanding, body of evidence about their differences. In fact to talk about the topic is to invite dismissal. Yet no one who knows anything about the area would dispute for an instant that there are significant differences: it’s just that no-one seems to know why. And we now know that every type of function – including reason, emotion, language and imagery – is subserved not by one hemisphere alone, but by both.
This book argues that the differences lie not, as has been supposed, in the ‘what’ – which skills each hemisphere possesses – but in the ‘how’, the way in which each uses them, and to what end. But, like the brain itself, the relationship between the hemispheres is not symmetrical. The left hemisphere, though unaware of its dependence, could be thought of as an ’emissary’ of the right hemisphere, valuable for taking on a role that the right hemisphere – the ‘Master’ – cannot itself afford to undertake. However it turns out that the emissary has his own will, and secretly believes himself to be superior to the Master. And he has the means to betray him. What he doesn’t realize is that in doing so he will also betray himself.
The book begins by looking at the structure and function of the brain, and at the differences between the hemispheres, not only in attention and flexibility, but in attitudes to the implicit, the unique, and the personal, as well as the body, time, depth, music, metaphor, empathy, morality, certainty and the self. It suggests that the drive to language was not principally to do with communication or thought, but manipulation, the main aim of the left hemisphere, which manipulates the right hand. It shows the hemispheres as no mere machines with functions, but underwriting whole, self-consistent, versions of the world. Through an examination of Western philosophy, art and literature, it reveals the uneasy relationship of the hemispheres being played out in the history of ideas, from ancient times until the present. It ends by suggesting that we may be about to witness the final triumph of the left hemisphere – at the expense of us all.
This course of 25 lectures, filmed at Cornell University in Spring 2014, is intended for newcomers to nonlinear dynamics and chaos. It closely follows Prof. Strogatz’s book, “Nonlinear Dynamics and Chaos: With Applications to Physics, Biology, Chemistry, and Engineering.”
The mathematical treatment is friendly and informal, but still careful. Analytical methods, concrete examples, and geometric intuition are stressed. The theory is developed systematically, starting with first-order differential equations and their bifurcations, followed by phase plane analysis, limit cycles and their bifurcations, and culminating with the Lorenz equations, chaos, iterated maps, period doubling, renormalization, fractals, and strange attractors.
A unique feature of the course is its emphasis on applications. These include airplane wing vibrations, biological rhythms, insect outbreaks, chemical oscillators, chaotic waterwheels, and even a technique for using chaos to send secret messages. In each case, the scientific background is explained at an elementary level and closely integrated with the mathematical theory. The theoretical work is enlivened by frequent use of computer graphics, simulations, and videotaped demonstrations of nonlinear phenomena.
The essential prerequisite is single-variable calculus, including curve sketching, Taylor series, and separable differential equations. In a few places, multivariable calculus (partial derivatives, Jacobian matrix, divergence theorem) and linear algebra (eigenvalues and eigenvectors) are used. Fourier analysis is not assumed, and is developed where needed. Introductory physics is used throughout. Other scientific prerequisites would depend on the applications considered, but in all cases, a first course should be adequate preparation.
The pioneering and still essential text on semantics, urging readers to improve human communication and understanding with precise, concrete language.
In 1938, Stuart Chase revolutionized the study of semantics with his classic text, The Tyranny of Words. Decades later, this eminently useful analysis of the way we use words continues to resonate. A contemporary of the economist Thorstein Veblen and the author Upton Sinclair, Chase was a social theorist and writer who despised the imprecision of contemporary communication. Wide-ranging and erudite, this iconic volume was one of the first to condemn the overuse of abstract words and to exhort language users to employ words that make their ideas accurate, complete, and readily understood.
From the man who Oliver Sacks hailed as “one of the best scientist/writers of our time,” a collection of sharply observed, uproariously funny essays on the biology of human culture and behavior.
In the tradition of Stephen Jay Gould and Oliver Sacks, Robert Sapolsky offers a sparkling and erudite collection of essays about science, the world, and our relation to both. “The Trouble with Testosterone” explores the influence of that notorious hormone on male aggression. “Curious George’s Pharmacy” reexamines recent exciting claims that wild primates know how to medicate themselves with forest plants. “Junk Food Monkeys” relates the adventures of a troop of baboons who stumble upon a tourist garbage dump. And “Circling the Blanket for God” examines the neurobiological roots underlying religious belief.
Drawing on his career as an evolutionary biologist and neurobiologist, Robert Sapolsky writes about the natural world vividly and insightfully. With candor, humor, and rich observations, these essays marry cutting-edge science with humanity, illuminating the interconnectedness of the world’s inhabitants with skill and flair.
For over three decades, Ray Kurzweil has been one of the most respected and provocative advocates of the role of technology in our future. In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: the union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.
