Author: P. A. LAGERSTORM

Fluid mechanics is one of the greatest accomplishments of classical physics.

The Navier-Stokes equations, first derived in the 18th century, serve as an accurate mathematical model with which to describe the flow of a broad class of real fluids.

Not only is the subject of interest to mathematicians and physicists, but it is also indispensable to mechanical, aeronautical, and chemical engineers, who have to apply the equations to real-world examples, such as the flow of air around an aircraft wing or the motion of liquid droplets in a suspension.

David Baron’s “The Martians” reconstructs a bizarre tale told through newly discovered clippings that began in the 1890s when Percival Lowell, a wealthy Harvard scion declared “there can be no doubt that living beings inhabit our neighboring world.”

So frenzied was the reaction that international controversies arose and a new genre called science fiction arose.

While Lowell’s claims were savagely debunked, his influence sparked a compulsive interest in Mars that continues to this day.

What We Are Reading Today: ‘Plato’s Second Republic’ by Andre Laks

In “Plato’s Second Republic”, Andre Laks argues that the “Laws,” Plato’s last and longest dialogue, is also his most important political work, surpassing the “Republic” in historical relevance.

Laks offers a thorough reappraisal of this less renowned text, and examines how it provides a critical foundation for the principles of lawmaking.

In doing so, he makes clear the tremendous impact the “Laws” had not only on political philosophy, but also on modern political history.

Laks shows how the four central ideas in the “Laws” — the corruptibility of unchecked power, the rule of law, a “middle” constitution.

What We Are Reading Today: Modeling Social Behavior by Paul E. Smaldino

This book provides a unified, theory-driven introduction to key mathematical and agent-based models of social dynamics and cultural evolution, teaching readers how to build their own models, analyze them, and integrate them with empirical research programs.

“Modeling Social Behavior” equips social, behavioral, and cognitive scientists with an essential tool kit for thinking about and studying complex social systems using mathematical and computational models.

What We Are Reading Today: Parfit by David Edmonds

Derek Parfit (1942–2017) is the most famous philosopher most people have never heard of.

Widely regarded as one of the greatest moral thinkers of the past hundred years, Parfit was anything but a public intellectual. Yet his ideas have shaped the way philosophers think about things that affect us all: equality, altruism, what we owe to future generations, and even what it means to be a person. In Parfit, David Edmonds presents the first biography of an intriguing, obsessive, and eccentric genius.

Believing that we should be less concerned with ourselves and more with the common good, Parfit dedicated himself to the pursuit of philosophical progress to an extraordinary degree.

He always wore gray trousers and a white shirt so as not to lose precious time picking out clothes, he varied his diet as little as possible, and he had only one serious non-philosophical interest: taking photos of Oxford, Venice, and St. Petersburg. In the latter half of his life, he single-mindedly devoted himself to a desperate attempt to rescue secular morality—morality without God—by arguing that it has an objective, rational basis.

Authors: Chantelle Jessica Lewis & Jason Arday

Ableism is embedded in our daily lives. Social life, education, work, and, especially, mental health have been organized around rigid ideas of the “ideal” and the “normal” citizen — ideas that always exclude neurodiversity.

In this pathbreaking book, Chantelle Jessica Lewis and Jason Arday argue that the neurodiversity movement offers ways to mobilize against not only ableism but also other “isms” including racism and capitalism. 

Lewis and Arday use theories of Blackness, feminism, class, and neurodivergence to offer a vision of solidarities across differences.
