Ever heard of “Composite Metal Foams” (CMFs)? Turns out, this technology has been around for quite a while and has a wide range of applications. These materials are tough enough to turn an armor-piercing bullet into dust on impact but weigh a fraction of plate armor.
Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, has spent years developing CMFs. The video below shows a specimen made out of her composite metal foams. The bullet in the video is a 7.62 x 63 millimeter M2 armor piercing projectile, which was fired according to the standard testing procedures established by the National Institute of Justice (NIJ). As you can see, the results were dramatic.
“We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters,” Rabiei says. “To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of an armor.”

Friends, The next generation of chess is here, and it involves Quantum Mechanics. Say what? As if the game isn’t difficult enough. Quantum Chess incorporates principles of quantum mechanics, such as superposition and entanglement, into regular chess gameplay. For example, a piece can exist in two places at the same time (superposition) until the player’s opponent observes the piece by moving another piece into one of the spaces that it might occupy, collapsing the quantum field and forcing it to exist in either one location or the other. And two pieces can become entangled when one piece tries to move through another that happens to be in superposition, joining their fates. The ultimate goal of the game is to kill the opponent’s king, not to reach checkmate. This is some pretty deep stuff; check it out…

Friends, we all know that your ammunition choice is just as important your weapon selection. One is basically useless without the other. That said, checkout Dynamic Research Technologies (DRT) Ammunition. According to the DRT website:
The powder core technology has been around for a while. However current examples on the market do not come apart uniformly and are not very accurate. DRT™ is the first company who has figured out how to stabilize the bullet in flight to achieve high accuracy and still have full frangibility.
The Terminal Shock bullet will not come apart until it hits something liquid or something harder than itself. This bullet is barrier blind – meaning it will go through barriers like bone, sheet rock, light steel, car doors, plywood, and siding, without expanding. It will not penetrate through a person, animal, water, or hardened steel, however. Think catastrophic fluid shift…
Found a cool video review here:
Friends, numerous high-profile military veterans from the wars in Iraq and Afghanistan and Hollywood talent like Danny Trejo and William Shatner will be starring in an upcoming movie called “Range 15.” The movie, whose trailer recently debuted at the Sundance Film Festival, appears to be riddled with profanity and gallows humor, and makes it clear that veterans will be in on all the jokes. Think “Sharknado,” but with more wisecracks about the military. Perfect!
Actors shown in the trailer include Marcus Luttrell and Mat Best, recent Medal of Honor recipients Leroy Petry and Clint Romesha and Tim Kennedy, a Special Forces soldier who also competes in mixed martial arts professionally in the UFC. Brian Stann, a Marine who earned a Silver Star for valor in Iraq and fought in the UFC, also makes an appearance. The movie is funded using donations from the crowd-funding website Indiegogo. To date, “Range 15″ has raised more than $1 million while promising that “this movie is so hardcore military it makes Hollywood wet itself and run home crying to mommy.”

An Artificial Intelligence (AI) built by Google’s DeepMind just beat a champion of the complex strategy game Go, a feat that may have enormous implications for AI research.
Go is often described as the “Chinese version of Chess,” but that description barely does the deceivingly simplistic game justice. The object of the game is to have majority control of the board. You do so by placing your white (or black) pieces (stones) on the board and using them to surround your opponent’s pieces so that they are forced to remove them. If it sounds less complicated than chess, it’s not. To put things in perspective, for each move in chess you have about 40 options. Each move on the 19-by-19 Go grid affords you 200 choices.
“There are more configurations on the board than there are atoms in the universe”
DeepMind applied machine learning with not one, but two neural networks called “Policy” and “Value.” Both look at Go’s myriad game play possibilities, but in two quite specific ways. Policy narrows the field of possible moves to a handful of promising ones, while Value looks for positive outcomes without driving all the way to every possible game conclusion. Policy network looks at some 30 million games by human Go experts to accurately predict moves up to 57% of the time. The previous record was 44%. AlphaGo essentially plays millions of games between its two neural networks and learns how to be a better Go player through trial and error and reinforcement learning.
Holy Catfish! If you are interested in reviewing the games AlphaGo played, you can see them here.
