Small rodents scampered about, occupying themselves in the daily accomplishments of their dismal lives. The tireless sun cast its parching rays of incandescense from overhead, half way through its daily revolution. Age worn hoof prints smothered by the sifting sands of time shone dully against the dust splattered crust of earth. The weather beaten trail wound ahead into the dust racked climes of the baren land which dominates large portions of the Norgolian empire. Store Your Documents In A Cool, Dry, Dark Place: Might I recommend Garth Marenghi’s Darkplace? It’s all fun and games until someone gets hurt, which, actually, is exactly the kind of situation this is intended for. They provide precise, clean, low-cost engagements with near-infinite magazines.” In their own words, this weapon “Identifies, tracks, and defends against enemy missiles, mortars, unmanned vehicles, swarming boat attacks and other ‘close-in’ defense situations. In this video, it accurately tracks and quickly destroys a tiny quadcopter. Take Raytheon’s own High-Energy Laser Weapon System: Pew Pew: Regarding modern laser weaponry, it’s surprisingly sophisticated and impressive.
(The work done by L’Esperance had more to do with complications from diabetes.) You can read more about that here, but the short version is, that led directly to LASIK surgery. He had important work to do: Shoot lasers at the bird. I’d Still Rather Eat Them: In 1981, the day after Thanksgiving, Rangaswamy Srinivasan brought his leftovers to work. Two guards keep watch over the documents and can activate the mechanism whenever they think they’re in danger. Each night, the documents are lowered into a 50-ton vault that is fireproof, waterproof, and atom-bomb-proof.
More Of A Treasure Protector: The Declaration of Independence (and Constitution) is protected by more than just bulletproof glass and inert gas. It’s a weird quirk, but this means that on average, on Earth, argon weighs more than potassium. There happen to be more isotopes of heavy argon on Earth, and more isotopes of light potassium. This is because the atomic mass is calculated by averaging the mass of each isotope of an element, by its abundance. Element 18 has an atomic mass of 39.948, while element 19 has an atomic mass of 39.098. Usually, the number of neutrons is commensurate with that increase in protons.Īrgon, however, weighs more than the next element, potassium. This makes sense: The elements are arranged by atomic number, which denotes how many protons are in its nucleus. Weight Problem: One thing you might have noticed is that, as we traverse the periodic table, each element has weighed more than the last one. But we’ll try to find time for their story when we get to those elements. They would go on to discover krypton and xenon, too, all within a few weeks of each other.
#ARGON MOLAR MASS FULL#
Argon was the easy one to discover, since it makes up one full percent of the Earth’s atmosphere. Return of Ramsay and Rayleigh: Argon was discovered by the same two guys who discovered neon, actually, a few years earlier. Good Reads: The Eye of Argon can be read in its entirety here, and I recommend that everyone do so.
