Hamas gunmen open fire on hundreds at music festival in southern Israel

Posted by in categories: media & arts, weapons

During the surprise assault on Israel by Palestinian militant group Hamas Saturday, gunmen opened fire on hundreds of young people during a dance music festival in the southern Israeli kibbutz of Re’im near the Gaza Strip, according to the Associated Press and multiple Israeli media outlets.

Witnesses told the Times of Israel that rocket fire was followed by gunshots fired into the crowd, as hundreds tried to flee.

“The music stopped and there was a rocket siren,” a young woman called Ortal told Israel’s Channel 12, according to Reuters. “Suddenly out of nowhere, they started shooting.”

New laser-based method could help scientists discover new puncture-resistant materials

Posted by in categories: particle physics, weapons

A bullet piercing the protective armor of a first responder, a jellyfish stinging a swimmer, micrometeorites striking a satellite: High-speed projectiles that puncture materials show up in many forms. Researchers constantly aim to identify new materials that can better resist these high-speed puncture events, but it has been hard to connect the microscopic details of a promising new material to its actual behavior in real-world situations.

To address this issue, researchers at the National Institute of Standards and Technology (NIST) have designed a method that uses a high-intensity laser to blast microscale projectiles into a small sample at velocities that approach the speed of sound. The system analyzes the energy exchange between the particle and the sample of interest at the micro level then uses scaling methods to predict the puncture resistance of the material against larger energetic projectiles, such as bullets encountered in real-world situations. This new method, described in the journal ACS Applied Materials & Interfaces, reduces the need to perform a lengthy series of lab experiments with larger projectiles and bigger samples.

“When you’re investigating a for its protective applications, you don’t want to waste time, money and energy in scaling up your tests if the material doesn’t pan out. With our new method we can see earlier if it’s worth looking into a material for its protective properties,” said NIST chemist Katherine Evans.

The Science of The Expanse

Posted by in categories: media & arts, science, space, weapons

The Expanse is one of the seminal sci-fi shows of the past decade. Set centuries in the future when humans have colonized the solar system, it’s been called one of the most scientifically accurate sci-fi shows of all time. But just how much does this hold up to scrutiny?

Warp drives may swim through spacetime

Posted by in categories: space travel, weapons

I recently wrote about how viscoelastic fluids can be used in liquid body armor to stop bullets. While spacetime isn’t a fluid in the traditional sense, it has many of the same properties. In particular, it deforms when a massive body or any energy at all passes through it. The spacetime manifold resists deformation and seeks to return to flatness whenever a massive body passes on. This property is elasticity.

How Quantum Physics Leads to Decrypting Common Algorithms

Posted by in categories: computing, encryption, information science, mathematics, quantum physics, weapons

The rise of quantum computing and its implications for current encryption standards are well known. But why exactly should quantum computers be especially adept at breaking encryption? The answer is a nifty bit of mathematical juggling called Shor’s algorithm. The question that still leaves is: What is it that this algorithm does that causes quantum computers to be so much better at cracking encryption? In this video, YouTuber minutephysics explains it in his traditional whiteboard cartoon style.

“Quantum computation has the potential to make it super, super easy to access encrypted data — like having a lightsaber you can use to cut through any lock or barrier, no matter how strong,” minutephysics says. “Shor’s algorithm is that lightsaber.”

Shinzo Abe Attacker Tetsuyo Yamagami Used A 3D Printed Gun, Shot From 10 Feet. Chilling Details Emerge

Posted by in categories: biotech/medical, security, weapons

Tokyo/New Delhi: Tetsuya Yamagami, who shot Shinzo Abe in Nara City, used a handmade gun to attack the former Japanese Prime Minister, said reports. The 41-year-old shooter, a resident of Nara City in Japan shot Abe in his chest from 10 feet away, said reports. For the unversed, Abe was shot during live address in Western Japan. The attack was a shock in one of the world’s safest countries with some of the strictest gun control laws. During interrogation, the attacker has confessed that he was dissatisfied with Abe.

NHK public broadcaster aired dramatic footage of Abe giving a speech outside of a train station in the western city of Nara. He is standing, dressed in a navy blue suit, raising his fist, when a gunshot is heard. Footage then shows Abe collapsed on the street, with security guards running toward him. He holds his chest, his shirt smeared with blood.

Second video shows the attempted assassination of former Japanese Prime Minister Shinzo Abe.

Tesla Cybertruck Will Be the Death of Traditional Auto Pickup Trucks!

Posted by in categories: space, weapons

Classic pickup trucks have been wiped out by Tesla, according to Dave Lee. The Cybertruck design is so much superior to any other pickup truck design that it is almost unavoidable that the traditional pickup truck will die a slow death. Let us take a closer look at what he has to say about it.

Since Tesla’s Cybertruck is their most innovative vehicle design yet, any other firm will have a tough time emulating its design. In a recent interview, Tesla’s principal designer discussed the Cybertruck: “It is a return to the fundamentals. Is a pickup vehicle what you are looking for? Do you have any ideas? What would you look for if you arrived from Mars?”
