Wheel Cycle Oscillations Energy Limit Modules
- In a physics lab in Amsterdam, there's a wheel that can spontaneously roll uphill by wiggling. This "odd wheel" looks simple: just six small motors linked together by plastic arms and rubber bands to form a ring about 6 inches in diameter. When the motors are powered on, it starts writhing, executing complicated squashing and stretching motions and occasionally flinging itself into the air, all the while slowly making its way up a bumpy foam ramp.

Quantum Quantum Computing Computer Quantum Information Science Physics Theory
- This year's Breakthrough Prize in Fundamental Physics honors some of the pioneers of quantum information science As billions of dollars pour into quantum computing and countries build communication networks secured by quantum encryption , the prominence of quantum information science has become increasingly hard to ignore. This year's Breakthrough Prize in Fundamental Physics honors four pioneers who combined math, computer science and physics to do "foundational work in the field of quantum ... [Read More]


Neutrons Protons Nuclei Collisions Size Distribution
- It may be hard to imagine that the debris of violent heavy ion collisions—which dissolve the boundaries of protons and neutrons and produce thousands of new particles—can be used to gain detailed insight into the properties of nucleons. However, new advances in experimental methods along with improved theoretical modeling have made it possible. Based on a state-of-the-art model for the colliding nuclei and the hydrodynamic evolution of the quark-gluon plasma produced in the ... [Read More]

Temperatures Chip Electric Circuit Temperature Low Temperatures Research
- Cooling materials to extremely low temperatures is important for basic physics research as well as for technological applications. By improving a special refrigerator and a low-temperature thermometer, scientists have now managed to cool an electric circuit on a chip down to 220 microkelvin -- close to absolute zero. Cooling materials to extremely low temperatures is important for basic physics research as well as for technological applications. By improving a special refrigerator and a ... [Read More]
