According to experts' statistical analyses, if you're expecting 10 guests for dinner on Christmas day, 15 crackers—those festive cardboard tubes filled with a one-size-fits-no-one paper hat, a small toy, and a groan-inducing ...

Physics: Not everything is where it seems to be

Scientists at TU Wien, the University of Innsbruck and the ÖAW have for the first time demonstrated a wave effect that can lead to measurement errors in the optical position estimation of objects. The work now published ...

Seeing things: Researchers teach computers to recognize objects

(PhysOrg.com) -- If computers could recognize objects, they could automatically search through hours of video footage for a particular two-minute scene. A tourist strolling down a street in a strange city could take a cell-phone ...

Travertine reveals ancient Roman aqueduct supply

For hundreds of years, the Anio Novus aqueduct carried water 87 km (54 miles) from the Aniene River of the Apennine Mountains down into Rome. Built between AD 38 and 52, scholars continue to struggle to determine how much ...

Using quantum smoothing for optical phase estimation

(PhysOrg.com) -- "There are many situations where we need to measure the classical properties of a quantum system," Elanor Huntington tells PhysOrg.com. "Optical phase estimation is one of these techniques, and it is central ...

Chemically scrubbing CO2 from the air too expensive

(PhysOrg.com) -- While it is possible to chemically scrub carbon dioxide from Earth's atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now. Best to focus on controls ...
