WIRED - ALL GUNS CAN kill, but they do not kill equally.

Compare the damage an AR-15 and a 9mm handgun can do to the human body: “One looks like a grenade went off in there,” says Peter Rhee, a trauma surgeon at the University of Arizona. “The other looks like a bad knife cut.”

The AR-15 is America’s most popular rifle. It has also been the weapon of choice in mass shootings from Sandy Hook to Aurora to San Bernardino. In Orlando this past week, the shooter used a Sig Sauer MCX, an AR-15 style rifle originally developed for special ops, to kill 49 people in the Pulse nightclub. The carnage sparked new calls to reinstate a ban on assault rifles like the AR-15, which were designed as weapons of war.

It’s possible to argue about everything when it comes to the politics of guns—including about the definition of “assault rifle” itself—but it’s harder to argue about physics. So let’s consider the physics of an AR-15.

A bullet with more energy can do more damage. Its total kinetic energy is equal to one-half the mass of the bullet times its velocity squared. The bullet from a handgun is—as absurd as it may sound—slow compared to that from an AR-15. It can be stopped by the thick bone of the upper leg. It might pass through the body, only to become lodged in skin, which is surprisingly elastic.

The bullet from an AR-15 does an entirely different kind of violence to the human body. It’s relatively small, but it leaves the muzzle at three times the speed of a handgun bullet. It has so much energy that it can disintegrate three inches of leg bone. “It would just turn it to dust,” says Donald Jenkins, a trauma surgeon at University of Texas Health Science Center at San Antonio. If it hits the liver, “the liver looks like a jello mold that’s been dropped on the floor.” And the exit wound can be a nasty, jagged hole the size of an orange.

These high-velocity bullets can damage flesh inches away from their path, either because they fragment or because they cause something called cavitation. When you trail your fingers through water, the water ripples and curls. When a high-velocity bullet pierces the body, human tissues ripples as well—but much more violently. The bullet from an AR-15 might miss the femoral artery in the leg, but cavitation may burst the artery anyway, causing death by blood loss. A swath of stretched and torn tissue around the wound may die. That’s why, says Rhee, a handgun wound might require only one surgery but an AR-15 bullet wound might require three to ten.

Then, multiply the damage from a single bullet by the ease of shooting an AR-15, which doesn’t kick. “The gun barely moves. You can sit there boom boom boom and reel off shots as fast as you can move your finger,” says Ernest Moore, a trauma surgeon at Denver Health and editor of the Journal of Trauma and Acute Surgery, which just published an issue dedicated to gun violence.

Handguns kill plenty of people too, of course, and they’re responsible for the vast majority of America’s gun deaths. But a single bullet from a handgun is not likely to be as deadly as one from an AR-15.

This needs to be done

When it comes to choosing passwords, a lot of us are very, very dumb. But Microsoft may have a solution to our stupidity: It has plans to create a dynamically updated list of moronic passwords that it won’t let you use.

In a blog post, Microsoft explains that it’s putting to use the insights it can glean from millions of leaked passwords in order to increase security. Rather than simply imposing rules about password length and complexity, it’s using publicly available information to create a list of commonly used passwords, which it simply won’t allow you to use.

The list will be continually updated based on new password leaks, so as people shift to using other dumb passwords, they’ll also be banned. Who knows, eventually we might all use strong passwords. Imagine!

The company claims to have already rolled out the feature to Microsoft Account Service—that’s Outlook, Xbox, OneDrive and the like—and it will also add the feature to accounts that use its Azure AD login system. You won’t notice a lot of difference until you choose a dumb password, at which point you’ll be prompted to stop being a moron—sorry, to “choose a password that’s harder for people to guess.”

Farewell, “123456", you were useful while you were allowed

If this thing is real it is awesome. Check out the video 
Smart mirrors aren’t new. But this is the very first one where I reflexively reached into my wallet and threw money at the screen.

Cool defense weapon
"Much like its much larger Iron Dome cousin, Trophy – which is called Windbreaker locally – tracks objects rapidly approaching the vehicle it is mounted on, via an array of fixed radar antennas placed around the vehicle. The system automatically predicts the objects trajectory and then instantly aims a launcher that fires a canister of ball bearings at high speed directly at the object"
Years ago, Israeli defense outfit Rafael developed the equivalent of a “bubble shield” for military vehicles. The Trophy Active Protection System basically blasts incoming missiles into oblivion with a turreted shotgun. Now this tech is finally running on American M1 Abrams tanks and Stryker armored vehicles.

Even though they used safety lines. You still need nerves of steel to do what they have done.

And he calls Ted Cruz a liar. What a hypocrate.
 
Share on Facebook 1 1 SHARES Donald Trump has attacked Ted Cruz roughly a billion times over the last week for having taken out loans from Citibank and Goldman Sachs. Like most everything Trump says, his attacks are short on facts and even shorter on making sense. He claims somehow that Cruz attempted to hide the loans, even though he openly disclosed them on public | Read More »
