Soldiers simply lit a wick and tossed the grenade -- as fast as they could. By the 18th century, these weapons had fallen out of favor: They weren't especially useful in the battle style of the time, and the simple design made them extremely dangerous. The weapon saw a ...
ArcelorMittal is not stopping at bioethanol production. In its quest for a greener footprint, the company is also focusing on the Torero project, which aims to partially replace fossil coal with bio-coal in the blast furnace. Bio-coal is derived from waste wood treated t...
However, the JSOW doesn’t carry a nuclear warhead. Against ships and armored vehicles, it’s a good precision weapon, but for bringing mass destruction against inter-dimensional invaders, it sucks. Also, Iron Man’s high-speed grapple with this weapon wouldn't happen like it does on ...
There is no way for any known penetrating bomb to bury itself deeply enough to contain a nuclear blast. This means that the B61-11 would leave an immense crater and eject a huge amount of radioactive fallout into the air. Diplomatically, the B61-11 is problematic because it violates the...
fast as a similarly-massed asteroid does when it passes by Earth, and interstellar objects, although more rare, can travel four to eight times as fast as an asteroid. Remember, since energy scales as ~velocity squared, this means that a comet could only be ~11% as massive as an asteroid...
“It’s short,” Schaefer tellsNational Geographic’s Adam Kovac. “It stays at peak brightness only a few hours and starts fading fast.” When will the nova occur? Astronomers don’t have an exact time for when the blast will go off, but they’re refi...
Which will almost certainly be either a Pixel 8a or the about-to-be introduced Pixel 9. Because even after the unfortunate end of my Pixel 5a, I still value a phone that gets Android updates as fast as Google can ship them, allows an unusual degree of repairability, and includes the Ho...
but they need to start thinking about the problem and to start that process we need to act now. As in TODAY. As Greta Thunberg proved with her sail to the UN and the port crises confirmed: if you don’t take immediate action on maritime problems they will be fast forgotten. You can ...
The main challenge in bringing a building down is controlling which way it falls. Ideally, a blasting crew will be able to tumble the building over on one side, into a parking lot or other open area. This sort of blast is the easiest to execute, and it is generally the safest way to...
