Scant Evidence of Power Laws Found in Real-World Networks
...a book for a general audience, Linked, in which he asserted that power laws are ubiquitous in complex networks. “Amazingly simple and far-reaching natural laws govern the structure and evolution...
Physicists Mourn Joe Polchinski, Developer of Deep Ideas and Paradoxes
...and space-time physics, the evolution of many-body systems, and long-range interactions in string theory. About 20 years ago, astrophysicists discovered that the expansion of the universe is accelerating, driven by...
The Simple Algorithm That Ants Use to Build Bridges
...said. Evolution has seemingly equipped army ants with just the right algorithm for on-the-go bridge building. Researchers working to build swarms of simple robots are still searching for the instructions...
Elusive Higgs-Like State Created in Exotic Materials
...that it was possible to use existing theoretical tools to explain the evolution of the Higgs mode. Keimer’s group found that the Higgs mode parallels the behavior of the Higgs...
To Test Einstein’s Equations, Poke a Black Hole
...response. Einstein’s field equations describe the evolution of the shape of space-time. You give the equations information about curvature and energy at each point, and the equations tell you the...
How Einstein Lost His Bearings, and With Them, General Relativity
...— describe how the shape of space-time evolves in response to the presence of matter and energy. To describe that evolution, you need to impose on space-time a coordinate system...
How the DNA Computer Program Makes You and Me
...humans, is much smaller than the X chromosome, as it has been losing genes over evolutionary time (note that the genes are still around: They have just migrated to other...
The Physics of Glass Opens a Window Into Biology
...and protein folding. And now it shows up all over the place: in patterns in evolution, in magnets, in the dynamics of social networks. I would say that’s because glasses...
The Universe Is Not a Simulation, but We Can Now Simulate It
...Wired.com. The evolution of magnetic fields in a 10-Megaparsec section of the IllustrisTNG universe simulation. Regions of low magnetic energy appear in blue and purple, while orange and white correspond...
