An eel-lectrifying future for autonomous underwater robots

Sweden called off the hunt for a submarine after a week-long underwater search in the Stockholm archipelago. Triggered by a reported sighting of a Russian submarine, the alleged 'invasion' had been widely anticipated by military ...

Plasmon-enhanced Polarization-selective filter

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer ...

Evidence of the big fix?

The theory of wormholes and multiverse suggests that the parameters of the Standard Model are fixed such that the total entropy at the late stage of the universe is maximized. We consider the radiation of the universe as ...

We can eliminate the major tornado threat in Tornado Alley

The annually recurring devastating tornado attacks in US Tornado Alley raise an important question: Can we eliminate the major tornado threat in Tornado Alley? Some people may claim that such a question is beyond imagination ...

D-Wave and predecessors: From simulated to quantum annealing

The D-Wave computer is currently the latest link of a long chain of computers designed for the solution of optimization problems. In what sense does it realize quantum computation? We describe the evolution of such computers ...
