We summarize the week's scientific breakthroughs every Thursday.
- Quantum Physics
Gell-Mann, Hartle spin a quantum narrative about reality
The “consistent histories” approach to quantum physics removes any role for people in creating “quasiclassical” reality.
- Physics
Transfixing tetrahedrons
Dervishes are Sufi Muslims who represent the revolving heavens with their spinning dance.
- Quantum Physics
‘QBists’ tackle quantum problems by adding a subjective aspect to science
Advocates of a program called “Quantum Bayesianism” take a subjective approach to resolving the paradoxes of quantum physics.
- Computing
Materials’ light tricks may soon extend to doing math
A simulation paves the way toward metamaterials that can perform ultrafast complex mathematical operations using light waves.
- Physics
Google search fails to find any sign of time travelers
A search of the Internet for signs of time travelers from the future fares no better than the party hosted by Stephen Hawking that nobody attended.
- Physics
