Los Alamos National Lab
In early June 1972, the world’s most intense proton beam was delivered through nearly a mile of vacuum tanks at the Los Alamos Neutron Science Center, or LANSCE. As the facility has evolved over five decades, that proton beam is now delivered to five state-of-the-art experimental areas, including the Isotope Production Facility.
Incorporating established physics into neural network algorithms helps them to uncover new insights into material properties
According to researchers at Duke University, incorporating known physics into machine learning algorithms can help the enigmatic black boxes attain new levels of transparency and insight into the characteristics of materials.
Researchers used a sophisticated machine learning algorithm in one of the first efforts of its type to identify the characteristics of a class of engineered materials known as metamaterials and to predict how they interact with electromagnetic fields.
But is it worth it?Starship’s road to launch has been one of soaring highs and dramatic explosions tempered by grinding regulatory procedures.
Elon Musk has announced that SpaceX’s Starship will make its first flight into orbit in July of this year. And this means the wait is nearly over.
Elon Musk is finally revealing some specifics of his Twitter content moderation policy. Assuming he completes the buyout he initiated at $44 billion in April, it seems the tech billionaire and Tesla CEO is open to a “hands-on” approach — something many didn’t expect, according to an initial report from The Verge.
This came in reply to an employee-submitted question regarding Musk’s intentions for content moderation, where Musk said he thinks users should be allowed to “say pretty outrageous things within the law”, during an all-hands meeting he had with Twitter’s staff on Thursday.
There are endless possibilities for the creative crafter. And for the more experienced DIY-ers, there’s an even bigger project that’s just waiting to be built for those daring enough to try: How about an entire guest house for your backyard? After an internet frenzy sold out this particular model, the DIY Allwood Solvalla Garden House is back in stock and better than ever.
If you’re not quite ready to move your entire life into a tiny space like this, never fear: You can convert it into a guest home, a studio, garden house, pool house, or truly anything your heart desires. Plus, you can purchase all the parts and instructions on Amazon.
At a mere 172 square feet, the tiny space is compact enough to actually fit but still has enough room to be useful, whether it’s used for storage or for pure fun. In the description, the plans say that this tiny structure can be built in way less than a day—in eight hours, to be exact—when two adults team up for the job.
Time travel makes regular appearances in popular culture, with innumerable time travel storylines in movies, television and literature. But it is a surprisingly old idea: one can argue that the Greek tragedy Oedipus Rex, written by Sophocles over 2,500 years ago, is the first time travel story.
But is time travel in fact possible? Given the popularity of the concept, this is a legitimate question. As a theoretical physicist, I find that there are several possible answers to this question, not all of which are contradictory.
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of thermodynamics or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.
The US Department of Defense’s innovative tech unit, the Defense Advanced Research Projects Agency (DARPA), is looking for ways to recharge drones while still in flight using laser-shooting tanker planes as the source of that energy.
“This Airborne Energy Well is a potential component of a more expansive energy web of power generation, transfer relays and receiving solutions, enabling the Department of Defense (DoD) to dynamically allocate energy resources to more flexibly deliver military effects,” the RFI notes.
