For nuclei crammed with 100-plus protons, a special type of physics takes center stage. Electrons zip around these giant nuclei, sometimes surpassing 80 percent the speed of light. According to Einsteinâ€™s special theory of relativity, when particles move that fast, they seem to gain mass. That property changes how closely the electrons hug the nucleus, and as a result, how easily the atoms share electrons to produce chemical reactions. In such atoms, â€œrelativity rules, and standard common wisdom breaks down,â€ says nuclear physicist Witold Nazarewicz of Michigan State University in East Lansing. â€œWe have to write new textbooks on those atoms.â€
The nucleus of superheavy oganesson has 118 protons and many neutrons (blue and red). Its 118 electrons (green) surround the nucleus. Carbon, which is much lighter, contains just six protons and six electrons (not to scale).
Some of the periodic tableâ€™s more familiar elements are already affected by special relativity. The theory explains why gold has a yellowish hue and why mercury is liquid at room temperature (SN: 2/18/17, p. 11). â€œWithout relativity, a car would not start,â€ says theoretical chemist [Pekka PyykkÃ¶ of the University of Helsinki. The reactions that power a car battery depend on special relativity.
No, not the mediocre at best 80s movie, but anything that sends a tickle through your cerebral cortex or straight up gives you a full on nerd boner.
There are no rules in this thread other than do not criticize or mock anyone for sharing something that you already knew and assumed everyone else to already know.
We all start somewhere, and knowledge is power.
This stuff reads like a junior high science reportThe "gay bomb" and "halitosis bomb" are formal names for two non-lethal psychochemical weapons that a United States Air Force research laboratory speculated about producing. The theories involve discharging female sex pheromones over enemy forces in order to make them sexually attracted to each other.
In 1994 the Wright Laboratory in Ohio, a predecessor to today's United States Air Force Research Laboratory, produced a three-page proposal on a variety of possible nonlethal chemical weapons, which was later obtained by the Sunshine Project through a Freedom of Information Act request.
Heh, human ingenuityBody odor remote-engineering, involving compounds found in halitosis and hyperhidrosis, was another possibility discussed. Again, these effects would be produced by a non-lethal chemical weaponâ€”possibly one that would affect the hormonal and digestive systems. It appears that a 'heavy sweating bomb', 'flatulence bomb' and 'halitosis bomb' were also considered by a committee at the time. The plan was to make an enemy so smelly they could be quite literally sniffed out of hiding by their opponents.
"The one interesting bit that I found recently in one of my briefs on the poppy industry was that we have a problem with wallabies entering poppy fields, getting as high as a kite and going around in circles,"
Saw a lot of genetic experiments conducted in the alleys of Chicago. Have no proof but must of been since the rat rapping my window was the size of a cougar. Could see it's muscle sinew tighten under the moonlight as the sap bastard flexed. Bang bang...didn't shoot him as I don't own a heater but gosh darn where da heck dey makin dese mathusalas?
I could really go for a fully loaded Chicago dog right now if ya catch what I'm pitchin.
Also, please don't tell me your avatar was taken in 1985.
