    ... direction as the pulsar orbits around its companion. Imagine a spinning top when its slightly non-vertical ... orientation. After four years of observations, they determined that its spin axis precesses just as Einstein predicted ...
  • Quantum chaos unveiled?

    ... of the Study: 'These Guys are Dancing Together' Technically, spin is the intrinsic angular momentum of a particle – a concept ... around the magnetic field axis like spinning tops. In this manner, the physicists created four ...
  • A young pulsar shows its hand

    ... -58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space ... of emission, suggesting that the pulsar may be precessing like a spinning top and sweeping an energizing beam around ...
  • NIST develops powerful method of suppressing errors in many types of quantum computers

    ... states evolve in a predictable way, similar to a spinning top tipped from its vertical axis. Environmental ... the original state. The NIST method is an adaptation of "spin echo" techniques used for decades to suppress errors ...
  • NASA's Fermi telescope probes dozens of pulsars

    ... is really beyond our wildest dreams." Like spinning tops, pulsars slow down as they lose ... from the companion can spill onto the pulsar and increase its spin. At rotation periods between 100 and 1,000 ...
  • UA scientists discover quantum fingerprints of chaos

    ... was directly visible in their images: They saw that the quantum spinning top observes the same boundaries between stability and chaos that characterize the motion of the classical spinning top. That is, both quantum and classical systems were dynamically ...
  • Magnetic mixing creates quite a stir

    ... whose direction is constantly spinning in a motion similar to a spinning top as it is about to collapse on its side, but much ... , such as a kind of washing machine agitation where the spinning direction alternates periodically. Currently, Martin ...
  • Massive quakes barely disturb Earth's rhythms

    ... and going of ice ages to an ongoing imbalance in the planet's rotation that make it wobble like a spinning top that's winding down. Southern California ...
  • Putting a spin on light and atoms

    ... measurement parameter over the best previous performance. In a spin-polarized population of atoms, more than half the atoms ... and cause it to precess like a spinning top that's been pushed off the vertical. Changes in the outside field ...
  • Caltech physicists demonstrate a four-fold quantum memory

    ... . Each ensemble can have atoms with internal spins that are "up" or "down" (analogous to spinning tops) and that are collectively described ... states, our experiment illustrates how multipartite entangled spin waves can evolve into various subsets of the entangled ...
  • Images show atom ‘spinning top’ control

    Precession of quantum mechanical angular momentum in atomic oxygen can be directed and pictured, potentially allowing more detailed reaction studies
  • Physicists measure current-induced torque in nonvolatile magnetic memory devices

    ... using magnetic fields. Instead, they use a mechanism called "spin torque," which arises from the idea that electrons have a fundamental spin (like a spinning top). When the electrons interact with the magnets ...
  • First Stars Were Spinning Tops

    Early suns likely spun at incredible speeds and ended their lives with massive gamma ray bursts
  • Galaxy Closeup Reveals Best-Ever Snapshot of Black Hole Jets

    ... image of the galactic core, but the jets are quite apparent, making Centaurus A look like a spinning top. The jets feed huge lobes of radio-emitting gas, which also reach far beyond ...
  • Electron is surprisingly round, say Imperial scientists following 10 year study

    ... careful measurements of the motion of these electrons. If the electrons were not perfectly round then, like an unbalanced spinning-top, their motion would exhibit a distinctive ...
