Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready in a decade.
A Heisenberg's dog is the central unit in a quantum computer that factors prime numbers. We report the outcome of a proof-of-principle Gedankenexperiment in which the number 3 was factored and good agreement was found both with an analytical theoretical prediction and with the results of a quantum Las Vegas calculation. Other future applications of Heisenberg's dog are hinted at. The anonymous reports of the referees and our reply to them are reproduced in appendix A and appendix B respectively.
Physicists have exploited the laws of quantum mechanics to generate random numbers on a Nokia N9 smartphone, a breakthrough that could have major implications for information security
Monopoly is one of the classic American games. It's played amongst close friends, loved ones, and trusted business partners.
It's also one of the few times in life where it's perfectly acceptable to want to systematically annihilate and crush the aforementioned friends, loved ones and partners.
We broke down the must-know math behind Monopoly as well as several lessons you can take away from what truly is The Most Dangerous Game.
Engineer : Remember to tip 18%, everybody. Mathematician : Is that 18% of the pre-tax total, or of the total with tax? Physicist : You know, it's simpler if we assume the system doesn't have tax. Computer Scientist : But it does have tax.
You can yell, "Beam me up, Scotty!" all you want, the only thing that will happen is you'll elicit a bunch of bemused stares from passersby wondering if you've bonked your head recently. The sad fact is human teleportation devices don't yet exist in 2013, and even if they did, the tremendous lag would make it extraordinarily impractical.
Always check your units!
Your units are wrong! cried the teacher.
Your church weighs six joules - what a feature!
And the people inside
Are four hours wide,
And eight gauss away from the preacher!
How Fermi could estimate things!
Like the well-known Olympic ten rings,
And the one-hundred states,
And weeks with ten dates,
And birds that all fly with one... wings.
For things moving free or at rest,
Observe what the first law does best.
It defines a key frame,
Inertial by name,
Where the second law then is expressed.
We propose a way of implementing an event cloaking device without the use of metamaterials. Rather than slowing down and speeding up light, we manipulate an obscurity gap by diverting the light through paths of appropriate length with an arrangement of switchable transreflective mirrors.
In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a drone. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.
A malaria vaccine has become the first to provide 100% protection against the disease, confounding critics and far surpassing any other experimental malaria vaccine tested. It will now be tested further in clinical trials in Africa.
Kirobo, a knee-high talking robot with red boots and a black and white body, has blasted off from Japan for the International Space Station to test how machines can help astronauts with their work.
Black-body radiation can give rise to a net attractive force between tiny objects. That is the claim made by physicists at the University of Innsbruck in Austria, who have calculated the strength of this new force between a speck of dust and a hydrogen atom. Under some cirmustances this force could be stronger than gravitation. Read the paper here: http://prl.aps.org/abstract/PRL/v111/i2/e023601
The French Space Agency (CNES) commissioned Damien Labrousse to recreate the Jupiter Mission Control Room in Lego for display at the Kourou spaceport. The impressive build features 6,000 bricks, 80 minifigs, a working video screen that shows the rocket launch sequence and a sound system, displaying launch countdown.
