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.
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.”
According to the video, Shor’s algorithm works off the understanding that for any pair of numbers, eventually multiplying one of them by itself will reach a factor of the other number plus or minus 1. Thus you take a guess at the first number and factor it out, adding and subtracting 1, until you arrive at the second number. That would unlock the encryption (specifically RSA here, but it works on some other types) because we would then have both factors.
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.

Science fiction amazes us with futuristic technology and weapons, but many like the laser pistol, raygun, or lightsaber seem high-tech versions of old tech. Are such weapons possible and if so, could they have a role in future warfare?

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?”
A strong vehicle that is hard to damage or break would benefit from a thick layer of armor plate on the exterior that is immune to gunshots and can be driven into trees without fear of scratching. 
Because you do not have to paint stainless steel, you utilize it. Scratches will not stick to stainless steel. Saving money and time by not having to paint is a huge benefit.
They may be tiny weapons, but Brigham Young University’s holography research group has figured out how to create lightsabers—green for Yoda and red for Darth Vader, naturally—with actual luminous beams rising from them.
Inspired by the displays of science fiction, the researchers have also engineered battles between equally small versions of the Starship Enterprise and a Klingon Battle Cruiser that incorporate photon torpedoes launching and striking the enemy vessel that you can see with the naked eye.
“What you’re seeing in the scenes we create is real; there is nothing computer generated about them,” said lead researcher Dan Smalley, a professor of electrical engineering at BYU. “This is not like the movies, where the lightsabers or the photon torpedoes never really existed in physical space. These are real, and if you look at them from any angle, you will see them existing in that space.”
Researchers from Utah have figured out how to use lasers to create sci-fi-style holograms inspired by phasers from ‘Star Trek’ and lightsabers from ‘Star Wars.’
HENDERSON, Nev.—(BUSINESS WIRE)—Artificial Intelligence Technology Solutions, Inc. (OTCPK: AITX), today announced that its wholly-owned subsidiary Robotic Assistance Devices (RAD) has entered into an agreement with EAGL Technology, Inc. to offer EAGL’s Gunshot Detection System (GDS) in all present and foreseeable future RAD devices.
“We have been receiving repeated requests that gunshot detection capabilities be built into RAD devices from industries as varied as transit operators, retail property managers, and law enforcement. Integrating EAGL’s technology into RAD’s autonomous response solutions should be well received by all of the markets we serve” Tweet this
EAGL Technology was established in 2015 after acquiring gunshot ballistic science developed by the Department of Energy (DOE) Pacific Northwest National Laboratory (PNNL). EAGL has advanced this technology by creating a state-of-the-art security system. The EAGL product offering utilizes the company’s patented FireFly® Ballistic Sensor technology which RAD will offer, as an integrated option, on all mobile and stationary security solutions. EAGL clients include Honeywell, Johnson Controls, Siemens and many more.
