Wormholes Untangle a Black Hole Paradox
...Joe Polchinski, a researcher at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, whose own stunning paradox about firewalls in the throats of black holes...
How Scientists Are Tackling the Tricky Task of Solar Cycle Prediction
...physics-based methods that are similar to complex climate prediction models. These computer simulations use fluid dynamics and electromagnetism to re-create solar physics; scientists then feed in observational data to anticipate...
Physicists Mourn Joe Polchinski, Developer of Deep Ideas and Paradoxes
...Institute for Theoretical Physics at the University of California, Santa Barbara, he interacted meaningfully with much of the theoretical physics community worldwide, conscious of the fact that important insights come...
Questioning Truth, Reality and the Role of Science
...it? Dismissive claims by famous physicists that philosophy is either a useless intellectual exercise, or not on a par with physics because of being incapable of progress, seem to start...
Can Space-Time Be Saved?
Curious connections between physics and math suggest to Latham Boyle that space-time may survive the jump to the next theory of reality. Most of today’s leading theoretical physicists have a...
A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.
...disorder may not be so easily overcome. It is a truth of both physics and everyday experience that things fall apart. Ice melts. Buildings crumble. Any object, if you wait...
How Can Some Infinities Be Bigger Than Others?
...am I right, that you were once trained in the world of physics? Moore (02:02): Yeah, it was a physics double major with math, when I was an undergraduate. I...
Dogged Dark Matter Hunters Find New Hiding Places to Check
...weakly interacting massive particles (WIMPs) and axions. These are the simplest formulations for dark matter, and each type of particle would also elegantly solve other physics mysteries. But after roughly...
A Mathematician Who Fled to Freedom but Still Stares Down Doubts
...liked physics. I did well in my physics classes, but never felt like I gained an intuitive understanding of everyday physical events. But when I started working with my Ph.D....
