Best of Last Week – Setting a quantum speed limit, slowing the speed of light and turning back the aging clock
Scientists set quantum speed limit
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to ...
Novel mathematical research for quantifying and predicting uncertainty in design models
Uncertainty is sometimes unavoidable. But in the world of scientific computing and engineering, at least, what's worse than uncertainty is being uncertain about how uncertain one is.
Discovery of uncertainty relations beyond the Heisenberg
In the quantum world, the famous Heisenberg uncertainty principle bounds the product of the variances of two incompatible observables such as the position and the momentum of a particle by the Planck constant. Heisenberg, ...
Best of Last Week – Quantum physics got less complicated, the pseudogap and ibuprofen as an anti-aging drug
Quantum physics just got less complicated
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct ...
Why Australia's entire power sector should support the Renewable Energy Target
There's been much talk about how uncertainty over the future of the (RET) is affecting the renewable energy industry.
Research reveals Germans born after the fall of the Berlin Wall suffered from bad parenting
Children born in East Germany shortly after the fall of the Berlin Wall suffered from poor parenting from "risk loving" mothers and were 40 per cent more likely to commit crimes as adults according to a new ...
Managers can boost creativity by 'empowering leadership' and earning employees' trust
Managers can promote creativity in employees by "empowering leadership" and earning employees' trust, according to a new study by Rice University and American University.
With few data, Arctic carbon models lack consensus
(Phys.org) —As climate change grips the Arctic, how much carbon is leaving its thawing soil and adding to Earth's greenhouse effect? The question has long been debated by scientists. A new study conducted ...
Where is that spacecraft? Statistically measuring uncertainty for space surveillance
Space surveillance is inherently challenging when compared to other tracking environments due to various reasons, not least of which is the long time gap between surveillance updates. "Unlike the air and missile defense environments ...
Carbyne morphs when stretched: Calculations show carbon-atom chain would go metal to semiconductor
(Phys.org) —Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator, according to Rice University scientists.
'Compressive sensing' provides new approach to measuring a quantum system
(Phys.org) —In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be ...
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
