These Tiny Spacecraft Could Lead Us to Alpha Centauri

Posted by in categories: computing, military, robotics/AI, satellites, solar power, sustainability

Earlier this spring, Russian billionaire Yuri Milner casually announced his intention to develop spacecraft that can travel at up to 20 percent the speed of light and reach Alpha Centauri within twenty years. From the outset, it was clear that no humans would be making the warp jump—the mission will involve extremely lightweight robotic spacecraft. A new fleet of tiny satellites hints at what those future interstellar voyagers will look like and be capable of.

Meet Sprites: sticky note-sized devices that sure look like the result of the Pentagon’s long-anticipated floppy disk purge, but are in fact state-of-the-art spacecraft complete with solar cells, a radio transceiver, and a tiny computer. Later this summer, a Cornell-led project called Kicksat-2 will launch 100 of these puppies to the International Space Station. There, the satellites will spend a few days field-testing their navigational hardware and communications systems before burning up in orbit.

The project’s lead engineers, Zachary Manchester and Mason Peck, are on the advisory committee for Breakthrough Starshot, an ambitious effort to reach our nearest neighboring star system within a generation. (In fact, the potato chip-sized computer Milner held up during a highly publicized press conference in April was Manchester’s own design.) Sprites, and the “chipsat” technology they’re based on, are a step toward that goal of interstellar travel. More generally, they’re an indication of the future of space exploration.

Behind the Commonwealth Bank’s investment in quantum computing

Posted by in categories: business, computing, finance, government, quantum physics

Excellent story; glad that this bank in Australia is getting prepared for Quantum now instead of later which will be too late for some. Good news is that Wall Street as well as the US Government are getting educated on Quantum Computing. I do hope more and more businesses and institutions start developing their own internal QC expertise so that they are prepared for the switch that is coming across all industries.


The Commonwealth Bank’s decision to contribute millions of dollars to quantum computing research is not just about the significant commercial potential of the technology itself but also about developing its own in-house expertise in the area, according to chief information officer David Whiteing.

The bank last year committed to contributing $10 million over five years to UNSW’s Centre for Quantum Computation and Communication Technology (CQC2T). That was in addition to $5 million it announced in December 2014 that it would put towards the centre.

Solid-state physics: Probing the geometry of energy bands

Posted by in categories: computing, mobile phones, particle physics, quantum physics

Scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich and the Max Planck Institute for Quantum Optics (MPQ) have devised a new interferometer to probe the geometry of band structures.

The geometry and topology of electronic states in solids play a central role in a wide range of modern condensed-matter systems, including graphene and topological insulators. However, experimentally accessing this information has proven to be challenging, especially when the bands are not well isolated from one another. As reported by Tracy Li et al. in last week’s issue of Science (Science, May 27, 2016, DOI: 10.1126/science.aad5812), an international team of researchers led by Professor Immanuel Bloch and Dr. Ulrich Schneider at LMU Munich and the Max Planck Institute of Quantum Optics has devised a straightforward method with which to probe band geometry using ultracold atoms in an optical lattice. Their method, which combines the controlled transport of atoms through the energy bands with atom interferometry, is an important step in the endeavor to investigate geometric and topological phenomena in synthetic band structures.

A wide array of fundamental issues in condensed-matter physics, such as why some materials are insulators while others are metals, can be understood simply by examining the energies of the material’s constituent electrons. Indeed, band theory, which describes these electron energies, was one of the earliest triumphs of quantum mechanics, and has driven many of the technological advances of our time, from the computer chips in our laptops to the liquid-crystal displays on our smartphones. We now know, however, that traditional band theory is incomplete.

What Will Electronics & Semiconductors Be Like In 100 Years?

Posted by in categories: computing, electronics, information science, nanotechnology, singularity

When I 1st read this headline, I had to pause and ask myself “was the article’s author informed at all on QC?” especially given China’s own efforts much less D-Wave, Google, and University of Sydney. And, then I read the article and I still have to wonder if the author is on top of the emerging technologies such as BMI, graphene, QC, and other nanotechnology that are already being tested to go live in the next 7 to 10 years plus much of the content is very superficial at best. I am glad that the author did put the tid bit on Singularity as the endpoint state; however, that is pretty well known. Nonetheles, sharing to let you be the judge.


For decades, we relied on silicon as the semiconductor for our computer chips. But now, working at nanometer scales, it looks like physical limitations may end the current methods to include more and more processing power onto each individual chip.

Many companies are making billion-dollar investments to continue scaling down semiconductor technology. The pressures of big data and cloud computing are pushing the limits of the current semiconductor technology in terms of bandwidth, memory, processing speed, and device power consumption.

Samsung’s new 512GB SSD is smaller than a postage stamp

Posted by in categories: computing, electronics, mobile phones

Storage in your laptop or smartphone is a compromise between volume, access speed and physical size. But, the industry’s competition to shrink them while boosting their specifications is fierce. A few months after shipping a 16TB solid-state drive, Samsung has announced a fast, efficient 512GB SSD that’s half the size of a postage stamp.

Samsung’s press release claims that the drive is the first mass-produced 512GB SSD with non-volatile memory express (NVMe), a host-controller interface with a streamlined register for speed, in a single package. Unlike other hard drives in multi-chip packages (MCP), Samsung’s new drive is organized in a ball grid array into a collected unit, making it simpler to fit in and connect to other parts in the device. This makes the drive ideal for the ultra-slim notebook PC market, where space and weight are at a premium.

A senior Samsung VP said in a press release that the tiny drive triples the performance of a typical SATA SSD. Its read/write speeds of up to 1,500MB/s and 900MB/s, respectively, mean you could transfer a 5GB HD video in 3 seconds. Samsung will start selling the drive in June in 512GB, 256GB and 128GB models.

Graphene That Behaves Like Water Can Pave Way For Chips That Can Model Black Hole, Supernova Behaviors

Posted by in categories: computing, cosmology, particle physics

Researchers used high-purity graphene and observed for the first time that its charged particles behave like fluid with relativistic properties. This discovery holds promise for thermoelectric devices as well as for studying the behavior of black holes and celestial bodies.

( Peter Allen/Harvard SEAS )

Electrons in graphene appear for the first time to behave like a liquid, potentially leading to devices that can efficiently convert heat to electricity and chips that can precisely model the behavior of black holes and high-energy celestial objects.

Artificial intelligence should be protected

Posted by in categories: computing, ethics, law, robotics/AI

With huge leaps taking place in the world of artificial intelligence (AI), right now, experts have started asking questions about the new forms of protection we might need against the formidable smarts and potential dangers of computers and robots of the near future.

But do robots need protection from us too? As the ‘minds’ of machines evolve ever closer to something that’s hard to tell apart from human intelligence, new generations of technology may need to be afforded the kinds of moral and legal protections we usually think of as ‘human’ rights, says mathematician Marcus du Sautoy from the University of Oxford in the UK.

Du Sautoy thinks that once the sophistication of computer thinking reaches a level basically akin to human consciousness, it’s our duty to look after the welfare of machines, much as we do that of people.

TruthSift: A Platform for Collective Rationality

Posted by in categories: biotech/medical, business, computing, disruptive technology, education, existential risks, information science, innovation, science, scientific freedom

“So there came a time in which the ideas, although accumulated very slowly, were all accumulations not only of practical and useful things, but great accumulations of all types of prejudices, and strange and odd beliefs.
Then a way of avoiding the disease was discovered. This is to doubt that what is being passed from the past is in fact true, and to try to find out ab initio again from experience what the situation is, rather than trusting the experience of the past in the form in which it is passed down. And that is what science is: the result of the discovery that it is worthwhile rechecking by new direct experience, and not necessarily trusting the [human] race[’s] experience from the past. I see it that way. That is my best definition…Science is the belief in the ignorance of experts.“
–Richard P Feynman, What is Science? (1968)[1]

TruthSift.com is a platform designed to support and guide individuals or crowds to rationality, and make them smarter collectively than any unaided individual or group. (Free) Members use TruthSift to establish what can be established, refute what can’t be, and to transparently publish the demonstrations. Anyone can browse the demonstrations and learn what is actually known and how it was established. If they have a rational objection, they can post it and have it answered.

Whether in scientific fields such as climate change or medical practice, or within the corporate world or political or government debate, or on day to day factual questions, humanity hasn’t had a good method for establishing rational truth. You can see this from consequences we often fail to perceive:
Peer reviewed surveys agree: A landslide majority of medical practice is *not* supported by science [2,3,4]. Scientists are often confused about the established facts in their own field [5]. Within fields like climate science and vaccines, that badly desire consensus, no true consensus can be reached because skeptics raise issues that the majority brush aside without an established answer (exactly what Le Bon warned of more than 100 years ago[6]). Widely consulted sources like Wikipedia are reported to be largely paid propaganda on many important subjects [7], or the most popular answer rather than an established one [8]. Quora shows you the most popular individual answer, generated with little or no collaboration, and often there is little documentation of why you should believe it. Existing systems for crowd sourced wisdom largely compound group think, rather than addressing it. Existing websites for fact checking give you someone’s point of view.

Corporate or government planning is no better. Within large organizations, where there is inevitably systemic motivation to not pass bad news up, leadership needs active measures to avoid becoming clueless as to the real problems [9]. Corporate or government plans are subject to group think, or takeover by employee or other interests competing with the mission. Individuals who perceive mistakes have no recourse capable of rationally pursuading the majority, and may anyway be discouraged from speaking up by various consequences[6].

Creation of Weak Materials Offers Strong Possibilities for Electronics

Posted by in categories: computing, electronics, physics

New fundamental research by UT Dallas physicists may accelerate the drive toward more advanced electronics and more powerful computers.

The scientists are investigating materials called topological insulators, whose surface electrical properties are essentially the opposite of the properties inside.

“These materials are made of the same thing throughout, from the interior to the exterior,” said Dr. Fan Zhang, assistant professor of physics at UT Dallas. “But, the interior does not conduct electrons — it’s an insulator — while the electrons on the surface are free to move around. The surface is therefore a conductor, like a metal, but it is in fact more robust than a metal.”

Quantum thermal transistor can control heat currents

Posted by in categories: computing, quantum physics

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in applications that recycle waste heat that has been harvested from power stations and other energy systems. Currently, there are methods for transporting and guiding this heat, but not for controlling, amplifying, and switching the heat on and off, as the quantum thermal transistor can do.

The researchers, Karl Joulain et al., at the University of Poitiers and CNRS in France, have published a paper on the quantum thermal transistor in a recent issue of Physical Review Letters.

“To manage electricity, one uses electronic diodes, transistor and amplifiers,” Joulain told Phys.org. “We would like to do the same thing with thermal currents. We would like to make logical thermal circuits in the same way electronic thermal circuits have been designed. In this way, wasted heat could be guided, switched on or off, amplified or modulated.”
