Submission + - Here Come the Robot Swarms (wsj.com)

Submitted by fjo3
fjo3 writes: Forget teaching robots to think like humans. A field called swarm robotics is taking inspiration from ants, bees and even slime molds—simple creatures that achieve remarkable feats through collective intelligence.

Unlike traditional robots that take orders from a central computer, swarm robots work like ant colonies. No single robot is in charge, but the swarm accomplishes complex tasks through simple interactions between neighbors. Each robot interacts only with those nearby, sometimes communicating with sounds or chemical signals in particles they release.

Comment Scientific research is moving ahead very fast. (Score 1) 7

Scientific research is rapidly improving our lives and our understanding.

AI, "Artificial Intelligence", is rapidly advancing in the normal way. Many mistakes are found in the initial methods.

We have, in many areas of Physics, a limited understanding of the world around us. This research is one example of improvement.

Submission + - Mathematical proof debunks the idea that the universe is a computer simulation (phys.org)

Submitted by alternative_right
alternative_right writes: Today's cutting-edge theory—quantum gravity—suggests that even space and time aren't fundamental. They emerge from something deeper: pure information.

This information exists in what physicists call a Platonic realm—a mathematical foundation more real than the physical universe we experience. It's from this realm that space and time themselves emerge.

"The fundamental laws of physics cannot be contained within space and time, because they generate them. It has long been hoped, however, that a truly fundamental theory of everything could eventually describe all physical phenomena through computations grounded in these laws. Yet we have demonstrated that this is not possible. A complete and consistent description of reality requires something deeper—a form of understanding known as non-algorithmic understanding."

Submission + - Japanese convenience stores are hiring robots run by workers in the Philippines

John.Banister writes: Teleoperated robot workers are here! No more worries about immigrants taking jobs, as the jobs themselves can be exported. Anything that isn't done by the cheapest labor can be exported to where the skilled labor is cheap. And, what better way to train AI replacements than the encoded stimulus and response of teleoperation?

Comment Eventually, less work for humans will be excellent (Score 1) 61

Quoting the story: "Human-only work is forecast to drop 27% over the next five years."

Robots will eventually be excellent for all of us. Most things we buy will cost less.

Maybe we will have 4-day or 3-day work weeks.

Humans will not be doing extremely boring jobs.

Submission + - Is Windows 7 about to overtake Windows 10? (gbnews.com)

Submitted by alternative_right
alternative_right writes: According to StatCounter, Windows 7 has been rapidly gaining market share in recent weeks — a full five years after support for the desktop operating system was officially terminated. At the latest count, Windows 7 is now used by some 22.65% of all Windows PCs worldwide. That's an increase from the 18.97% just a little over a month ago.

As of last month, users were already switching to Windows 7 in record numbers, but that number had only totalled to 9.6% worldwide.

Submission + - How we sharpened the James Webb telescope's vision from a million kilometers awa (theconversation.com)

schwit1 writes: Hubble started its life seeing out of focus – its mirror had been ground precisely, but incorrectly. By looking at known stars and comparing the ideal and measured images (exactly like what optometrists do), it was possible to figure out a “prescription” for this optical error and design a lens to compensate.

The correction required seven astronauts to fly up on the Space Shuttle Endeavour in 1993 to install the new optics. Hubble orbits Earth just a few hundred kilometers above the surface, and can be reached by astronauts.

By contrast, Webb is roughly 1.5 million kilometers away – we can’t visit and service it, and need to be able to fix issues without changing any hardware.

This is where AMI comes in. This is the only Australian hardware on board, designed by astronomer Peter Tuthill.

It was put on Webb to diagnose and measure any blur in its images. Even nanometers of distortion in Webb’s 18 hexagonal primary mirrors and many internal surfaces will blur the images enough to hinder the study of planets or black holes, where sensitivity and resolution are key.

AMI filters the light with a carefully structured pattern of holes in a simple metal plate, to make it much easier to tell if there are any optical misalignments.

We wanted to use this mode to observe the birth places of planets, as well as material being sucked into black holes. But before any of this, AMI showed Webb wasn’t working entirely as hoped.
