A four-stroke engine for atoms
If you switch a bit in the memory of a computer and then switch it back again, you have restored the original state. There are only two states that can be called "0 and 1.".....»»
Scientists create the thinnest lens on Earth, enabled by excitons
Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists from the University of Amsterdam and Stanford University have made a flat lens of only three atoms thick that relies on quantum e.....»»
Successful engine test boosts Vega-C toward return-to-flight
The Zefiro-40 solid rocket motor, the second stage of the Vega-C rocket, was tested today by Vega-C prime contractor Avio at its Salto di Quirra test facility in Sardinia, Italy. The motor features an improved engine nozzle design, required to prepar.....»»
