A simplification of superfluidity

"Once people tell me what symmetry the system starts with and what symmetry it ends up with, and whether the broken symmetries can be interchanged, I can work out exactly how many bosons there are and if that leads to weird behavior or not," Murayama said. "We've tried it on more than 10 systems, and …

SciAm’s new blog on the block!

Scientific American has announced the introduction of a new blog, Critical Opalescence, edited by senior editor George Musser. It will focus on the quirky and the fascinating, attempting to revive interest in forgotten papers, explain usually complex phenomena, and generally potter around with interesting inventions and discoveries.

Big Fish walked into a wall. His large nose tried to penetrate the digital concrete first. Of course, it went in for a second, but Marcus recomputed the algorithm, and it jumped back out. The impact of its return threw Big Fish’s head back, and with it, his body stumbled back, too. The wall hadn’t …

Universality of the Lotka-Volterra equations

If humankind were to discover a planet that harbours water, and if, by some provenance, the same unicellular organisms that were the precursors to Earth-bound evolution were to be introduced into this environment... Would the significant differences between our evolutionary pattern and their evolutionary pattern be equivalent in any measure to the significant differences between …

Winterwolf VII

At that moment, the semi-AI beeped completion, and 34 jumped out of the chair in one fluid motion and lunged at 32, pinning him to the floor as the gun spilled from his hand and clattered a few feet away. Did you upgrade yourself?! 32 simply smiled. I REPEAT, DID YOU UPGRADE YOURSELF?! “No!” Why …

Winterwolf VI

“Right. Caution. Good. Anyway, where was I? Yes! Evolution! This race of new humans was enabled to evolve at an accelerated pace, to mutate and reform within a decade without having to wait for a million years, with a genetically implanted trigger that would terminate mutatory control once human intelligence was reached.” The New Chance. …

Winterwolf V

The alarms didn’t bother him; no one would believe an upgraded cyborg could have committed murder. On the other hand, the CEs 32 and 34 were the only cyborgs aboard the Winterwolf, and would quickly turn suspect if the intervention of any other Earthborn could be ruled out. Of course, the Earthborn were quite capable …

Winterwolf IV

CE34 came to life. He felt great innocence, although that could have meant nothing in particular to CE34 because he wouldn’t have known the corruption of innocence. The room he was in was empty. Nothing odd about that. His memories, his knowledge signaled nothing disturbing or being as cause for concern. He looked down. His …

Winterwolf III

Noiselessly, the two jaws holding the first pellet, nicknamed the Bald Eagle, unclamped and withdrew, the hydraulic pistons powering their ductile muscles being emptied of all air. As the cylinders withdrew slowly, the pellet came loose, for a moment just hanging limp in space before a trigger went off deep within its titanium heart, igniting …

Winterwolf II

Snapping him out of attention, suddenly, was a long-toned beep from the semi-AI monitoring CE34’s upgrade. “Warning! Sentience encountered!” the screen displayed in bold, green lettering. CE32 didn’t understand: 34’s quantum compiler had activated itself even though the activation sequence had been carefully subtracted from his pseudo-memories. Within 32’s bulbous silicone head, a small screen …

Winterwolf I

A Tesla coil stood alone in the middle of a vast desert, the manganese-rich pink-red dust characteristic of the planet whipped around its splayed feet by incessant winds. The coil itself was actually a tower a mile high, and halfway to its top, a series of coaxial superconducting rings were held in position by nanotube …
