  • How Jews Became White Folks and What That Says about Race in America (Karen Brodkin)

    Karen Brodkin examines how American Jews’ changing racial position reshaped Jewish identity, class, and belonging across generations.

    She contrasts immigrant experiences of antisemitic exclusion with the postwar opportunities available to many Jews of European descent.

    Her account links access to education, professional employment, and suburban housing to public policy and the unequal distribution of opportunity.

    Moving between family history and social analysis, she distinguishes institutional racial assignment from the identities people make for themselves.

    The discussion follows her arguments about race, class, gender, and the tensions between Jewish distinctiveness and acceptance into white America.

  • Jews and Power (Ruth R. Wisse)

    Ruth R. Wisse traces Jewish political life from the loss of ancient sovereignty through emancipation and the creation of Israel.

    She examines how covenant, communal self-government, and accommodation sustained Jewish communities in the Diaspora.

    Wisse argues that dependence on rulers’ protection left Jews vulnerable to political movements that profited from targeting them.

    She follows the shift from religious hostility to modern political antisemitism and examines how demagogues turned Jewish success into conspiracy narratives.

    The discussion closes with her argument that moral responsibility requires collective self-defense, including in the modern state of Israel.

  • The Necessity of Exile (Shaul Magid): Essays from a Distance

    Shaul Magid reconsiders exile as a resource for Jewish life rather than a condition that political sovereignty simply ends.

    Across nine essays, he examines liberal Zionism, American Jewish identity, communal belonging, and the boundaries of political dissent.

    Drawing on Hannah Arendt, Martin Buber, Hasidic thinkers, and Yiddish literature, he develops his idea of counter-Zionism.

    He asks how Jewish self-determination can coexist with Palestinian self-determination and critiques claims of exclusive ownership of the land.

    The book distinguishes antisemitism from structural oppression and explores an exilic ethic of humility and coexistence, including within Israel.

  • Conceptual Form (Sandeep Prasada): The Hidden Structure of Commonsense Concepts

    Sandeep Prasada argues that commonsense concepts have a formal structure that guides how we think, speak and reason.

    Conceptual Form distinguishes what we know about a category from the perspectives through which we understand its members.

    The book develops an instance-of-kind perspective and examines how people reason about kinds, individuals and their properties.

    It applies this account to generic statements, systematic polysemy and metaphor, connecting conceptual structure with language.

    The later chapters consider how these perspectives are acquired and what they imply for theories of conceptual knowledge.

  • Unsupervised Learning for Physical Interaction through Video Prediction (Chelsea Finn, Ian Goodfellow & Sergey Levine)

    Chelsea Finn, Ian Goodfellow and Sergey Levine investigate how robots can learn the effects of physical interactions from unlabeled video.

    Their action-conditioned models predict how pixels move between frames, reusing visual appearance rather than reconstructing every future image from scratch.

    The paper introduces a dataset of 59,000 robot-pushing interactions and tests predictions on previously unseen objects.

    Its experiments compare alternative motion-prediction architectures and examine their ability to produce plausible futures conditioned on a robot's actions.

    This 2016 work provides an early foundation for robotic world models and connects visual prediction with the longer-term goal of planning through learned models.

  • La-JEPA: Compact Robot Policies with Latent World Modeling (Mateo Clémente et al.)

    Mateo Clémente and colleagues introduce La-JEPA, a compact robot policy trained in the feature space of a pretrained V-JEPA 2.1 video encoder.

    The model learns to predict future visual features alongside actions during training, then generates actions alone when controlling the robot.

    The authors evaluate it on LIBERO-Plus, RoboTwin 2.0 and four real-robot tasks, reporting strong results with smaller policies than several generation-based alternatives.

    Their design study compares JEPA features with video-VAE latents and examines which forms of predictive supervision improve control.

    The paper also identifies corrupted instructions in the released LIBERO-Plus evaluator and re-evaluates baselines under a corrected protocol.

  • Robotics, Vision and Control (Peter Corke) — Part 5 of 5: Vision-Based Control

    The final part connects the series’ robotics and vision foundations through vision-based control.

    Position-based visual servoing uses estimated spatial quantities, while image-based visual servoing acts on errors measured in image features.

    The interaction matrix links motion to changes in the image, making the choice of features, depth estimates and camera model consequential.

    Advanced methods include partitioned, polar-coordinate and spherical-camera approaches to visual servoing.

    Applications to robot arms, mobile robots and aerial robots close the perception-to-action loop and expose the assumptions and performance limits of the methods.

  • Robotics, Vision and Control (Peter Corke) — Part 4 of 5: Computer Vision

    Part 4 follows the book’s five computer-vision chapters, from the physical properties of light to information recovered from multiple images.

    Light, color and image-processing operations explain how measurements become usable digital representations.

    Region, line and point features provide ways to describe structures and establish correspondences in images.

    Camera models and calibration relate image measurements to the geometry of the world.

    Multiple-view geometry and stereo methods show how relationships between images reveal depth, structure and motion, preparing the transition to visual feedback control.

  • Robotics, Vision and Control (Peter Corke) — Part 3 of 5: Robot Manipulators

    Part 3 turns from moving a robot’s base to controlling the motion of a robot arm.

    Forward and inverse kinematics connect joint configurations with the position and orientation of the end effector.

    The manipulator Jacobian relates joint velocity to task-space motion and reveals the significance of singularities and manipulability.

    Dynamics adds mass, inertia and the forces or torques required to produce a desired movement.

    Corke’s control methods connect these models with the practical problem of making an arm follow a commanded motion.

  • Robotics, Vision and Control (Peter Corke) — Part 2 of 5: Mobile Robotics

    Part 2 follows Corke’s treatment of mobile robots, navigation, localization and mapping.

    Vehicle models explain how wheeled and aerial robots can move, and which motions their physical constraints permit.

    Reactive behavior and map-based path planning offer different ways to reach a destination while handling obstacles.

    Odometry and probabilistic localization address the uncertainty in a robot’s estimate of where it is.

    Mapping and SLAM bring motion, measurements and environmental structure together, showing why navigation depends on both geometry and reliable estimation.
