Non-abelian Aharonov-Bohm experiment done at long last

Posted by in categories: computing, information science, particle physics, quantum physics

For the first time, physicists in the US have confirmed a decades-old theory regarding the breaking of time-reversal symmetry in gauge fields. Marin Soljacic at the Massachusetts Institute of Technology and an international team of researchers have made this first demonstration of the “non-Abelian Aharonov-Bohm effect” in two optics experiments. With improvements, their techniques could find use in optoelectronics and fault-tolerant quantum computers.

First emerging in Maxwell’s famous equations for classical electrodynamics, a gauge theory is a description of the physics of fields. Gauge theories have since become an important part of physicists’ descriptions of the dynamics of elementary particles – notably the theory of quantum electrodynamics.

A salient feature of a gauge theory is that the physics it describes does not change when certain transformations are made to the underlying equations describing the system. An example is the addition of a constant scalar potential or a “curl-free” vector potential to Maxwell’s equations. Mathematically, this does not change the electric and magnetic fields that act on a charged particle such as an electron – and therefore the behaviour of the electron – so Maxwell’s theory is gauge invariant.

Are You Developing Skills That Won’t Be Automated?

Posted by in categories: education, employment, robotics/AI, transportation

The jobs that are likely to be automated are repetitive and routine. They range from reading X-rays (human radiologists may soon have much more limited roles), to truck driving, to stocking a warehouse. While much has been written about the sorts of jobs that are likely to be eliminated, another perspective that has not been examined in as much detail is to ask not which jobs will be eliminated but rather which aspects of surviving jobs will be replaced by machines.

The future of work looks grim for many people. A recent study estimated that 10% of U.S. jobs would be automated this year, and another estimates that close to half of all U.S. jobs may be automated in the next decade. The jobs that are likely to be automated are repetitive and routine. They range from reading X-rays, to truck driving, to stocking a warehouse. In this context, employers say that they’re seeking candidates who have other sorts of “soft skills,” such as being able to learn adaptively, to make good decisions, and to work well with others. These sought-after abilities, of course, fit perfectly with the sorts of things that people can do well, but are and will continue to be difficult to automate. All of this suggests that our educational systems should concentrate not simply on how people interact with technology (e.g., by teaching students to code), but also how they can do the things that technology will not be doing soon. These are the skills that are hardest to understand and systematize, and the skills that give — and will continue to give —humans an edge over robots.

Here’s how blockchain could stop corrupt officials from stealing school lunches

Posted by in categories: bitcoin, computing, economics, governance, security

The World Economic Forum has partnered with the Inter-American Development Bank and the Colombian Inspector General’s Office to explore how distributed ledger technology can improve public transparency and integrity in school meal procurement.

The project, which is taking place this year, is multi-faceted and includes a software implementation with blockchain technology for the selection of school food vendors. It is co-designed with several partners from academia, the IT industry, and the non-profit world, including economists and computer scientists from the blockchain economics and governance consulting firm Prysm Group, the National University of Colombia, U.C. Berkeley, and the blockchain security firm Quantstamp.

This new wearable tech is closing the gap between humans and cyborgs

Posted by in categories: computing, cyborgs, engineering, wearables

A professor at the University of Chicago believes he is on his way to creating a wearable for market that will manipulate your muscles with electrical impulses to cause you to move involuntarily so you can perform a physical task you otherwise didn’t know how to do, like playing a musical instrument or operating machinery.

Dr. Pedro Lopes, who heads the Human Computer Integration lab at the university, is all about integrating humans and computers, closing the gap between human and machine. His team, which focuses on engineering the next generation of wearable and haptic devices, is exploring the endless possibilities if wearables could intentionally share parts of our body for input and output, allowing computers to be more directly interwoven in our bodily senses and actuators.

Lopes’ vision: a wearable EMS device that would look like a sleeve and be able to send electrical impulses in the right timing and in the right fashion to make a user’s muscles move involuntarily to perform a physical task. EMS stands for electrical muscle stimulation.

Amazon’s Vesta no-show highlights the challenges of home robots

Posted by in category: futurism

Amazon was expected to announce a home robot this week. It didn’t — perhaps because the market is more challenging than the company anticipated.

UPS Gets FAA Approval to Run America’s First Drone Delivery Airline

Posted by in category: drones

The Federal Aviation Administration has given UPS approval to run a drone fleet, enabling the company to create a UAV delivery airline.

UPS announced on Tuesday that the federal agency granted the company a Part 135 certification—a high level of certification used by charter airlines—to operate its drones. This permits UPS to fly drones that carry loads exceeding 55 pounds, to fly drones at night, and to fly the devices out of sight of operators. As UPS puts it, the “certification has no limits on the size or scope of operations.”
