Physicsworld runs down the top 2007 stories in the world of physics by month.
1. January : Map sheds light on dark matter
2. February: International Linear Collider plans are unveiled
3. March: Graphene meets negative refraction
4. April: Rogue neutrino is ruled out
5. May: Physics loses a polymer pioneer
6. June: Large Hadron Collider misses 2007 start up
7. July: The ongoing saga of the supersolid
8. August: The latest schemes for stopping light
9. September: Quantum computers get on the buses
10. October: GMR pioneers scoop Nobel Prize
11. November: Cosmic-ray mystery solved at last
12. December: US and UK physicists face funding cuts
Then AIP culls it down to a top ten:
In chronological order during the year:
- Light, slowed in one Bose Einstein condensate (BEC), is passed on to another BEC (link);
- Electron tunneling in real time can be observed with the use of attosecond pulses (link);
- Laser cooling of coin-sized object, at least in one dimension (link);
- The best test ever of Newton’s second law, using a tabletop torsion pendulum (link);
- First Gravity Probe B first results, the measurement of the geodetic effect---the warping of spacetime in the vicinity of and caused by Earth-to a precision of 1%, with better precision yet to come (link).
- The MiniBooNE experiment at Fermilab solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino (link);
- The Tevatron, in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously (link);
- The shortest light pulse, a 130-attosecond burst of extreme ultraviolet light (link);
- Based on data recorded at the Auger Observatory, astronomers conclude that the highest energy cosmic rays come from active galactic nuclei (link);
- And the observation of Cooper pairs in insulators (link).
Then Topography of Ignorance just says that it's the neutrino thing.
