For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible ...

Recent advances in space robotics have underscored the need for modeling, estimation, and control frameworks that respect the intrinsic geometry of ...

New simulations created by astrophysicists at the Flatiron Institute and the Institute for Advanced Study reveal how material flowing around and into black holes creates intense light shows. The ...

Abstract: Implantable wireless bioelectronic devices enable communication and/or power transfer through RF wireless connections with external nodes. These devices encounter notable design challenges ...

We present analytic expressions that approximate the behavior of the spacetime of a collapsing spherically symmetric scalar field in the critical regime first discovered by Choptuik. We find that the ...

The post on my blog, has much more details on the math of how to bridge the attention operator (a nonlinear operator)'s approximation capacity with a linear operator (Petrov-Galerkin projection). The ...

Through telescopes on Earth and in space, astronomers can glimpse the far-flung reaches of the universe. And no matter how far away or how strange the planet, at least one thing seems to hold true in ...

Inside the highly secretive military branch responsible for protecting American interests in a vulnerable new domain. A patch for the Assured Access to Space Directorate, the Space Force division in ...
