It is important to note that nuclear power plants emit less radioactive material than do coal-fired stations (uranium and other radioactive isotopes are found naturally in coal ash and soot) [9]. The most severe environmental impact associated with nuclear energy is due to the mining of ...
“In the case of our Moon, the Apollo sample has strongly indicated that the Moon was once molten and that the Moon and Earth are isotopically very similar,” explains Hyodo. Isotopes are atoms of the same element that have slightly different weights due to the number of neutrons in theatom...
(there are also the usual things aboutpolitics, plus some deliberately wacky ones like whether Elon Musk will buildmore kilometers of tunnel than Trump does border wall) They’re doing good work – online for-cash prediction markets are limited to a couple of bets by the government, and they...
-bound ships. so after 10 years and more than $1 billion spent on scanners, radiation detectors, and beefed-up intelligence, most u.s. ports are still scanning containers onshore, after unloading. unfortunately, the detectors are easily foiled. lots of harmless things are slightly radioactive ...
Then there are other experiments that utilise magnetic field confinement produced by electric currents. Some like thePolywellone have been going for many years with multiple generations of its energy production structure. Another which arose from ideas within the Polywell device andadded elements of acc...
"But they've also found some really interesting things, such as licence plates, cans of spam and nails." "So they've got a very broad diet." Tiger sharks may search for food as they move up and down through the water column, Sammy says. ...
Number theorists expected some variation, but what they found far exceeded expectations. Primes are separated by different gaps; for example, 23 is six numbers away from 29. But 3-then-9 primes like 23 and 29 are far more common than 7-then-3 primes, even though both come from a gap ...
From Baja California to Puget Sound, scientists are seeing signs that gray whales are in distress. And they have no idea why.
however, can only be tested when a heat generating machine is operating". Then follows the most often quoted sentence of the report: "As there are in any substance some free neutrons, it would suffice for the ignition of the explosive to unite a sufficient amount (presumable 10–100 kg)....
