PRIMER-V2 robot rides a bike just like a man. It maintains balance with a built-in gyroscope, through which he holds the balance and steers in a straight line.
“Beyond implementation of quantum communication technologies, nanotube-based single photon sources could enable transformative quantum technologies including ultra-sensitive absorption measurements, sub-diffraction imaging, and linear quantum computing. The material has potential for photonic, plasmonic, optoelectronic, and quantum information science applications…”
In optical communication, critical information ranging from a credit card number to national security data is transmitted in streams of laser pulses. However, the information transmitted in this manner can be stolen by splitting out a few photons (the quantum of light) of the laser pulse. This type of eavesdropping could be prevented by encoding bits of information on quantum mechanical states (e.g. polarization state) of single photons. The ability to generate single photons on demand holds the key to realization of such a communication scheme.
By demonstrating that incorporation of pristine single-walled carbon nanotubes into a silicon dioxide (SiO2) matrix could lead to creation of solitary oxygen dopant state capable of fluctuation-free, room-temperature single photon emission, Los Alamos researchers revealed a new path toward on-demand single photon generation. Nature Nanotechnology published their findings.
The media is all-abuzz with tales of Artificial Intelligence (AI). The provocative two-letter symbol conjures up images of invading autonomous robot drones and Terminator-like machines wreaking havoc on mankind. Then there’s the pervading presence of deep learning and big data, also referred to as artificial intelligence. This might leave some of us wondering, is artificial intelligence one or all of these things?
In that sense, AI leaves a bit of an ambiguous trail – there does not seem to be a clear definition, even amongst scientists and researchers in the field. There are certainly many different branches of AI. I asked Dr. Roger Schank, Professor Emeritus at Northwestern University, for a more clear definition; he told me that artificial intelligence is not big data and deep learning algorithms, at least not in the pure sense of the definition.
Roger emphasizes that intelligence has everything to do with the intersection of learning and interaction and memory. “I will tell you the number one thing people do, it’s pretty obvious – they talk to each other. Guess how hard that is? That is phenomenally hard, that is the subsection of AI called natural language processing, the part that I worked on my whole life, and I understand how far away we are from that.”
Take a “simple” AI concept, such as how to create a computer that plays chess, to better understand the challenge. There are, more or less, two approaches to creating an intelligent machine that can play chess like a champion. The first approach requires programming the computer to predict thousands of moves ahead of time, while the second approach involves building a computer system that tries to imitate a grand master. In the historical pursuit of how to create an artificially intelligent entity, a vast majority of scientists chose the first option of programming based on prediction.
I invite you all to like my new Facebook community page meant to be a place to discuss extrasolar planet-related issues as they relate to my seminal book on the subject: “Distant Wanderers: The Search for Planets Beyond the Solar System.” https://www.facebook.com/pages/Distant-Wanderers-The-Search-…294?ref=hl
Distant Wanderers: The Search for Planets Beyond the Solar System, my first book, was published in October 2001.
Citizens of the Thai capital Bangkok witnessed a huge fireball descending on the horizon this morning, and thanks to the dashcams in their cars, we can admire the celestial visitor from several different angles.
The meteor entered Earth’s atmosphere around 8.45am local time, and burnt up in a huge fireball after striking down from the sky. The meteor was big and bright, but definitely smaller than the infamous Chelyabinsk meteor which exploded over Russia in 2013, damaging 7,200 buildings in six cities in the southern Ural region. There are no reports of any damage from Bangkok so far.
We put together a short video about the Bangkok shooting star, for you viewing pleasure:
IFA is the world’s leading trade show for consumer electronics and home appliances. It takes place from September 4 to 9, 2015 in Berlin.
A growing number of tech moguls are trying to solve their biggest problem yet: aging.
From reprogramming DNA to printing organs, some of Silicon Valley’s most successful and wealthy leaders are investing in biomedical research and new technologies with hopes of discovering the secret to living longer.
And their investments are beginning to move the needle, said Zoltan Istvan, a futurist and transhumanist presidential candidate.
SpaceX’s super sized Falcon Heavy rocket has a new launch date: spring 2016. That’s according to remarks given by Lee Rosen, SpaceX’s vice president of mission and launch operations, at a conference in Pasadena this week. Space News reports the executive as saying, “It’s going to be a great day when we launch [the Falcon Heavy], some time in the late April – early May timeframe.”
We’ve been hearing about the Falcon Heavy for some time, but it has seen its share of delays. It will be the world’s most powerful operational rocket, capable of launching 115,000 pounds (53,000 kg) into low-Earth orbit. In history, it only comes short of the Saturn V rocket, which powered NASA’s Apollo missions to the moon. SpaceX originally promised to launch the rocket for the first time in 2013. It was then pushed back to this year, but the project was put on ice following the failure of a Falcon 9 rocket on June 28th.
“Stonehenge is an iconic and mysterious English landmark, but it’s not the only place to attract the interest of local archaeologists. Nearly 100 stone monoliths have been discovered at a site called the Durrington Walls, about two miles north-east of Stonehenge. For the average visitor, there’s little to see at ground level — just the grassy remains of a sloping bank. But with ground-penetrating radar, researchers have mapped the area and discovered evidence of up to 90 stones three feet underground. Around 30 remain intact, measuring up to 4.5 meters tall, while fragments of a further 60 lay beside them.”
Boeing Space Taxis in a couple of years.
This past Friday, Boeing unveiled its most recent assembly plant in Florida, only the new facility won’t be building commercial jets or fighter aircraft. Instead, it will be building spaceships, yes actual spaceships.
Boeing is aiming to have its soon-to-be-flown spaceships in the air and space by 2017. Dubbed the CST-100 Starliner, the spaceships could potentially be the first commercial spacecrafts on the market, though Boeing is in a tight race with SpaceX.
