Digital Archaeology 3D Modeling Reveals Ancient Artifacts

Media Platforms Design TeamEvery archaeological site contains a wealth of information about the past, and context is key. A knife found by a stone hearth tells a different story than one alongside a human skeleton. Unfortunately, excavating the site to reveal the story also destroys it. Detailed records are the only way archaeologists can keep archaeology from erasing the past rather than preserving it. Today, they’re using 3D modeling tech to preserve the information found in a site, find new places to dig, or create models of ancient artifacts via 3D printing....

Fast Radio Bursts Repeating Radio Signals Are A Deep Space Mystery

This article was updated on January 11, 2019 with comment from paper author Cherry Ng. In 2007, radio astronomers discovered what they love most: a mystery. Two researchers, combing the archives of the Parkes Observatory in Australia, found a radio signal the observatory recorded six years prior, but that nobody had noticed. It was fast—just a matter of milliseconds—but what impressed them was the power behind the signal, emitting 500 times the energy of the sun....

First Black Hole Image Eht Black Hole Picture

We’ve detected black holes time and time again, but we’ve always relied on indirect evidence to do so. But that all changed today with the first-ever image of an event horizon, the “point of no return” of a black hole. The Event Horizon Telescope consortium unveiled its first black hole image today. The “telescope” is actually a group of telescopes around the planet to create what the project refers to as a “planet-sized virtual telescope....

How To Build Steps Into Any Building

Well-designed steps create a great first impression, and when properly built, they will last for years. Popular Mechanics Senior Designer Michael Stillwell and his father Tony Stillwell recently designed and built steps into their barn, and shared their project with us.The designer of any steps has a responsibility not to make them difficult or dangerous to walk down or climb. To achieve this, you must take into account an easy slope to walk up, and each step must be consistent with all of the others....

How To Make Your Own Apps

Media Platforms Design TeamBefore ever suiting up, all fire-engine operators are taught about friction loss, in which water pressure is reduced by friction inside a fire hose. It’s a complicated calculation, dependent on hose diameter, type and length, as well as water velocity. Getting it right is vital. Many departments post cheat sheets for estimating pressure. Mike Raben, a firefighter in Louisville, Colo., found a more modern solution online: a custom-built calculator app for Google Android phones....

Meet Steve The Sky Light Phenomena That S Not Aurora Borealis

Auroras are among the most spectacular phenomena in the night sky, thrilling travelers and photographers with wispy displays of green light. But these auroras are not the only thing lighting up the night. Scientists have determined that streaks of purple captured by amateur photographers are not auroras at all, but are rather an entirely new type of celestial phenomenon. The streaks of strange light have come to be known as STEVEs....

Nasa Astronauts Share Thoughts On The Moon Landing Ahead Of First Man

View full post on YoutubeNASA astronauts have shared how the moon landing evokes tons of pride ahead of the release of First Man, which recounts the successful mission. In the clip shared exclusively with Popular Mechanics, astronauts Scott Kelly, Garret Reisman and Peggy Whitson talk about the ingenuity and risk-taking that thrust Apollo 11 to the lunar surface and America to the top of the Space Race in 1969. Reisman says the moon landing is still “the gold standard for doing something incredibly hard,” even as technology has evolved far beyond its late 20th century capabilities....

Our Favorite Feature The Alfa Romeo 4C S Data Mad Digital Displays

Media Platforms Design TeamThe first thing I noticed about the 2015 Alfa Romeo 4C was the color. It’s not quite burgundy, there’s a hint of silver, and in certain lighting conditions it takes on an almost purple hue. The Italians call it Competizione Red. To be fair, I would drive this beauty if it were pink with Hello Kitty decals on the hood. The second thing I noticed is the display....

Painting A Mars Rover Is Even More Complicated Than You D Think

Aesthetics aren’t exactly a priority for any Mars rover, but that doesn’t mean a paint job isn’t crucial to success. Beyond offering a clean, minimal look, white paint can create an important reflective surface for any space-bound object. The Mars 2020 rover recently got its paint job, and that process is a microcosm for the level of detail that’s required for each and every part. There are no paint shops on Mars, after all....

Russia S Apocalypse Missile Keeps Crashing

Vladimir Putin’s much-hyped nuclear-powered cruise missile is having trouble staying in the air. The Russian president announced the weapon in March as part of a package of new nuclear arms, but the unnamed missile has crashed four times in four months. The new Russian cruise missile takes advantage of a nuclear chain reaction for power. According to CNBC the missile uses a gasoline-powered engine, likely a turbojet similar to the one powering the Kalibr cruise missile (see above, using its rocket booster motor) to achieve flight....

The Sky Phenomenon Locals Named Steve Is Finally Explained

Amateur Canadian sky-watchers have spent years viewing and photographing a streak of light across the sky. Too far south to be the aurora borealis, or northern lights, the spectators named the phenomenon simply, “Steve,” in an homage to a 2006 animated film. But until now, it was unclear to scientists what Steve actually was. A new paper in Science Advances proposes a theory. Importantly, the researchers also gave Steve an official name: Strong Thermal Emission Velocity Enhancement, or STEVE....
