At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these enigmas, we take what we know about space, time, gravity and quantum mechanics and apply it to a place where all of those things simply break down. There is, perhaps, nothing… Continue reading New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes
Trump Administration Starts Firing Energy Department and Other Employees
CLIMATEWIRE | The Trump administration fired federal employees on probationary status Thursday, affecting tens of thousands of staffers nationwide. The Department of Energy, Forest Service and Office of Personnel Management are among the agencies that axed staffers, several current and former federal employees said. All agency employees for this story were granted anonymity because they… Continue reading Trump Administration Starts Firing Energy Department and Other Employees
How ‘Event Scripts’ Structure Our Personal Memories
He tweaked a machine learning technique called a hidden Markov model so it would work with fMRI data. The algorithm can be trained to recognize structure for events that stretch out over time, such as an episode of a TV show. The approach, borrowed from computer science, was new to neuroimaging. “That gave me a… Continue reading How ‘Event Scripts’ Structure Our Personal Memories
Catalytic Computing Taps the Full Power of a Full Hard Drive
The breakthrough came months later, when Buhrman was visiting his frequent collaborator Richard Cleve at the University of Waterloo. They decided to focus on an extreme scenario, one where the full memory is very large. If a computer with little free memory can access this massive full memory, would that enable it to solve problems… Continue reading Catalytic Computing Taps the Full Power of a Full Hard Drive

After 20 Years, Math Couple Solves Major Group Theory Problem
After the conjecture was posed in the 1970s, dozens of mathematicians tried their hand at proving it. They made partial progress — and in the process they learned a great deal about groups, which are abstract objects that describe the various symmetries of a mathematical system. But a full proof seemed out of reach. Then… Continue reading After 20 Years, Math Couple Solves Major Group Theory Problem
The Rebel Campus Boosters Rising Up Against Wokeness on Campus
Shown, the Silent Sam statue at the University of North Carolina, before and after the Confederate symbol was toppled in 2018 (below left and above). Things have changed: Alumni foes of campus radicals are getting organized, raising money, and fighting back. By John Murawski, RealClearInvestigstionsFebruary 19, 2025 In the plummy world of alumni relations, where… Continue reading The Rebel Campus Boosters Rising Up Against Wokeness on Campus
Undergraduate Upends a 40-Year-Old Data Science Conjecture
Together, Krapivin (now a graduate student at the University of Cambridge), Farach-Colton (now at New York University) and Kuszmaul demonstrated in a January 2025 paper that this new hash table can indeed find elements faster than was considered possible. ln so doing, they had disproved a conjecture long held to be true. “It’s an important… Continue reading Undergraduate Upends a 40-Year-Old Data Science Conjecture
Why the Argument for Birthright Citizenship Is Not the Slam Dunk Many Say It Is
By Paul D. Thacker, RealClearInvestigationsFebruary 19, 2025 President Trump often trumpets American exceptionalism, but an executive order scheduled to take effect this week seeks to uproot a longstanding policy not found in much of the developed world: granting citizenship to the children of illegal immigrants born on U.S. soil. Under his order, the babies would,… Continue reading Why the Argument for Birthright Citizenship Is Not the Slam Dunk Many Say It Is
How Hans Bethe Stumbled Upon Perfect Quantum Theories
In a spin chain, that motion is waves like those seen at stadiums. Flip one atom, and it will flip its neighbors, who will flip their neighbors, and so on. These waves are still extremely complicated; when two waves ripple through the same stretch of particles, any particle can flip any other particle, leading to… Continue reading How Hans Bethe Stumbled Upon Perfect Quantum Theories
