Talking Points: Martin Rees on Complexity

The Institute Letter Spring 2018

Phenomena with different levels of complexity are understood in terms of different irreducible concepts—turbulence, survival, alertness, and so forth. The brain is an assemblage of cells; a painting is an assemblage of chemical pigment. But what’...

Talking Points: Edward Witten on Dualities

The Institute Letter Spring 2018

How do we fit into our mathematical descriptions? Well, one thing I’ll tell you is that in general, when you have dualities, things that are easy to see in one description can be hard to see in the other description. So you and I, for example,...

The Persistence of Gender Inequality

By Joan Wallach Scott

Why—despite decades (indeed centuries) of social protest, policy initiatives, educational reform, nongovernmental organization activity, national and international legislation—does gender inequality persist?

Establishing a Theoretical Understanding of Machine Learning

"It's kind of like physics in its formative stages—Newton asking what makes the apple fall down," says Sanjeev Arora, Visiting Professor in the School of Mathematics, explaining the current scientific excitement about machine learning.

A Conversation with Juan Maldacena

The Institute Letter interviews Juan Maldacena on quantum information, spacetime, and efforts to understand how the view of black holes as a quantum computer is consistent and compatible with black holes from Einstein’s theory of general relativity.

Mathematics and Computation

By Avi Wigderson

In stark contrast to the elegant, concise algorithmic gems, which were man-made, many new algorithms simply “create themselves,” with relatively little intervention from humans, mainly through interaction with massive data.

Science and Culture: From Gene Patenting to Physics, Technology, and Public Policy

By Myles W. Jackson

My work in the history of science probes the porous boundaries between science and culture over the past two centuries. Much of it gestures toward the role of history in public policy. I am interested in having the historian at the table while a scientific controversy is ongoing. We historians are rather good at illustrating that controversies have histories: how we arrived at where we are today is very informative. There have always been, and always will be, alternatives.

How Our Brains Operate

We want to understand how mind emerges from brain, just as we understand how tornadoes emerge from molecules.

Using next-generation sequencing, it is possible to examine past populations in their complex genetic heterogeneity.

Life: A Critical User’s Manual

By Didier Fassin

Cyclical movement of nature and worldly events, biology and biography: these are the two series that make life an entity at once overdetermined in its material dimension and indeterminate in its course . . . Can this binarism be resolved? Is it possible to think of life as biology and life as biography together?

Black Holes and the Information Paradox in String Theory

By Juan Maldacena

What if black holes behave like ordinary quantum mechanical objects—and information about them is not lost, as previously thought, but retained on their horizons?

History, Climate, and the New Past

By Nicola Di Cosmo

Seen in the light of the antiquarian precedent, there is reason to believe that the contribution of the sciences of the past to historical research can help produce new histories. Yet, a word of caution is required.

Exploring the Topology of Locally Symmetric Spaces

By Akshay Venkatesh

Locally symmetric spaces are the home of the Langlands program—a set of overarching and interconnected conjectures connecting representation theory to number theory, first proposed in 1967 by Robert Langlands, now Professor Emeritus in the School of Mathematics.

The Advent and Fallout of EPR

An IAS teatime conversation in 1935 between Nathan Rosen, Boris Podolsky, and Albert Einstein, about a fundamental issue of interpretation related to entangled wave-functions, introduced an ongoing debate over quantum physics.

The Cool Alter-Ego of a Black Hole

Black holes are spacetime geometries where the flow of time is distorted in a major way. What type of resource is a pair of entangled black holes?

Who Wrote the Torah?

In light of more than two hundred years of scholarship, the most precise answer to this question still is: We don’t know. The tradition claims it was Moses, but the Torah itself says otherwise.

Embedded Portraits: Appending a New Myth to an Old Myth

By Christopher S. Wood

The world is emergent and always unfolding in time. Painting has difficulty representing this kind of time. The portrait tries to do that, paradoxically, by representing the individual fixed in historical time.

How Do You Know a Nuclear Weapon Works If You Can't Test It?

In 1987, in my third year as a graduate student in anthropology, I arrived in the small California town of Livermore, host to one of two nuclear weapons design laboratories in the United States. . . . intent on understanding the culture of the scientists, mainly physicists, who worked on the most powerful weapons on Earth.

A Mathematical Rosetta Stone

By Robbert Dijkgraaf

It is difficult to convey the enormous impact of his revolutionary idea. Langlands showed how the same formula can originate from two entirely different worlds of thought. To employ another metaphor: it is as if two chefs cooking with two entirely different recipes, ingredients, and methods of preparation, produce exactly the same dish.

Security vs. Civil Liberties and Human Rights

By Daniela Luigia Caglioti

The outbreak of the war transformed them––independently of their personal story, feelings, ideas, and sense of belonging––into enemy aliens, accused of posing a threat to national security. As the war went on, the campaign against enemy aliens extended well beyond individuals who had originated from an enemy country. The loyalty of groups of citizens was questioned based on ethnic origin, religious belief, or former nationality.

A World of Prisons: An Ethnography of the Carceral Condition

By Didier Fassin

In France, the expansion of the prison population with its socioracial component occurred at the very moment when socioeconomic inequalities started to deepen after a long period of contraction and when ethnoracial minorities became the target of stigmatization campaigns from right-wing parties. The penal state has definitely been a way of governing the poor.

I think there is no better introduction to Kelly’s work than his earlier years in Paris, especially when it comes to understanding why things that look apparently very simple are in fact much more complex than they seem.

The Prisoner’s Dilemma

I do not take the Prisoner’s Dilemma seriously as a model of evolution of cooperation. I consider it likely that groups lacking cooperation are like dodoes, losing the battle for survival collectively rather than individually.

Authoritarian Culture in the Arab World

By Kevin W Martin

After seizing power on his own behalf in December 1949, Army Colonel Adib al-Shishakli effectively ruled Syria for much of the next five years, during which he wrought long-term changes in Syria’s political culture and initiated a host of policies and practices subsequently adopted by Egypt’s Gamal Abdul Nasser, Syria’s Hafez al-Assad, Iraq’s Saddam Hussein, and other authoritarian rulers.
