The CO2 atmosphere is the least of your worries. Temperature on Venus is hot enough to melt lead, one day is 243 earth days, clouds made of sulphuric acid and a pressure 90 times greater than that on earth's surface. It would be hard to conceive of a single celled organism that could survive the conditions on Venus, le... | since venus' atmosphere is mostly co_2, making it too hot for human life, what is preventing us from introducing high tolerance plant life to convert the co_2 into oxygen, to make it inhabitable? | <P> A number of approaches to terraforming are reviewed by Martyn J. Fogg (1995) and by Geoffrey A. Landis (2011). Eliminating the dense carbon dioxide atmosphere The main problem with Venus today, from a terraformation standpoint, is the very thick carbon dioxide atmosphere. The ground level pressure of Venus is 9.2 M... |

There's no way the SNP can get a majority in the UK Parliament. They are only contesting 59 out of 650 seats (the ones in Scotland). So there is no realistic way Nicola Sturgeon can become PM. She actually isn't standing for election herself anyway, because she is a member of the Scottish Parliament and Scottish First ... | what happens if the snp are voted for in the general election? | <P> Nicola Sturgeon retained her post as First Minister under an SNP minority government. 2017 United Kingdom general election The SNP underperformed against polling expectations, losing 21 seats to bring their Westminster MPs down to 35. In what was largely attributed to their stance on holding a second Scottish indep... |
This is pure conjecture, but perhaps it is a relic of past times when the value of a coin was tied to the value of the metal used to make it. Gold is the most valuable, so you could have a $5, $10, $20, etc coin, with the value determined by how much gold is in it. Silver is less valuable, and in the US, quarters were ... | why are the united states' coins and canada's coins basically the same size, shape, and color? what happened that the two countries decided this would be a good idea? | <P> Coins of the Canadian dollar Denominations There are six denominations of Canadian circulation coinage in production: 5¢, 10¢, 25¢, 50¢, $1, and $2. Officially they are each named according to their value (e.g. "10-cent piece"), but in practice only the 50-cent piece is known by that name. The three smallest coins ... |
So, to fire a gun there is a firing pin, which you can see in this gif striking the back of a cartridge, igniting the powder and firing the gun. *Most* cartridges are center fire, with a primer in the middle (the silvery middle part of the back of a cartridge) but some are rim fire. Here is an illustration of the diffe... | in films, when a gun, usually a pistol, is dropped or thrown onto the ground, it will sometimes fire. is this something real guns do too, and if so, why, since the trigger isn't being pulled? | <P> When the gun was ready to fire, a round would be in the chamber and the bolt and barrel group would be locked together, with the locking block at the rear of the bolt. When the rear of the trigger was pivoted upwards by the operator, the front of the trigger tipped downward, pulling the sear out of engagement with ... |
Very frequently it is completely marketing, with little to no research backing up the claims. "Superfood" is not a regulated term, so anyone can slap it on their product, and anyone can write a blog post claiming that anything is a superfood. That said, dietary research *is* an active science, and new discoveries are f... | who decides what the next "superfood" is? how did we not already know something is good for us? is it just a marketing ploy to get rid of old stock? | <P> and self-help books about fad diets, promising an enhancement to health. "Superfood" products were sold at a higher price than similar foods not marketed with the label.

fly fishing uses an extremely light line and lure - not bait, usually something as light and basic as a small collection of feathers with a small hook. To cast, you whip the line back and forwards, feeding out more line with each pendulum swing so you can build enough momentum to send the tiny lure out far enough. This... | what is fly fishing? what differentiates it from other types of angling? | <P> Surf fishing Surf fishing is the sport of catching fish standing on the shoreline or wading in the surf. A general term, surf fishing may or may not include casting a lure or bait, and refers to all types of shore fishing – from sandy and rocky beaches, rock jetties, or even fishing piers.

Rutherford was influenced by Prout's hypothesis that all atoms were made up of groups of hydrogen atoms, with the hydrogen atom being the fundamental particle. The logic was that the atomic weights known at the time were almost exactly integer multiples of the mass of hydrogen. If there were smaller particles, there wo... | how did ernest rutherford know that the the positively charged particles in a nucleus were equal in magnitude of charge to electrons? | <P> to give the hydrogen nucleus a special name as a particle, since he suspected that hydrogen, the lightest element, contained only one of these particles. He named this new fundamental building block of the nucleus the proton, after the neuter singular of the Greek word for "first", πρῶτον. However, Rutherford also ... |
Bismarck led the creation of a welfare state for a few main reasons: * Reduce social unrest, and prevent an uprising like the Paris Commune of 1871.

Colonial rule was r... |
Through out the republican and imperial periods of Roman history, important figures like consuls, generals, senators, and later emperors were issued with official types of their portraiture. This consisted of an approved (by some authority, whether the artist or subject or both is contested) bust of their head. So all ... | how did commoners before the advent of photographs recognize "famous people" in the past without seeing them before? | <P> a portrait head. In Rome, an ideal figure of a divinity might often be adapted slightly (here, for instance the chiton covers the breast) and given a separately made portrait head. Evidence that this was the case here can be seen in the locks of hair falling onto the shoulders. These are also seen in posthumous por... |
Over the past 20 years Venezuela socialized their industry and began running the government very poorly. One instance is that they started setting rules on how much stores could charge for food so that everyone could afford it. The stores couldn't afford to sell anymore so they restricted how much the farmers could cha... | why is the u.s. sanctioning venezuela? | <P> and the establishment of the Bolivarian government, improvements in healthcare were promising due to the installation of free healthcare facilities and programs, and the assistance of Cuban medical professionals.

Lyndon Johnson was a Democrat from Texas. He stunned the Southern Democrats by strongly supporting the Civil Rights Act of 1964. A huge swath of these Southern Democrats defected to the Republican Party and that greatly helped Richard Nixon win the 1968 presidential election with his southern strategy. Storm Thurmond a... | has any modern leader of a western country made a controversial decision/order that no one expected once he became the leader? | <P> Party's Solid South since the end of the Reconstruction era in the 1870s, the Democratic nomination for statewide office had long been considered tantamount to election.

Is your question about the use of the word "militia" or the use of dictionaries? If you're asking about militias, the _URL_10_ definition is correct. In all the colonies, able-bodied men from the ages of 16 to 60 were typically required to join the county militia. Later on, this would change to the ages of 18 to 45, as... | language of the american founding fathers | <P> hunting and rural living.
Prior to the American Revolution, there was neither budget nor manpower nor government desire to maintain a full-time army. Therefore, the armed citizen-soldier carried responsibility. Service in militia, including providing one's own ammunition and weapons, was mandatory for all men. Yet,... |
You assume right. The (whole) island of Timor was first conquered and administered by Portuguese colonialists, from the 16th century onwards. They set up both commercial outposts and catholic missions. From the 17th century onwards, the Dutch came over and conquered nearly all of Indonesia, including Western Timor. How... | how did east timor come to exist? | <P> the island. Classical era Before European colonialism, Timor was included in Chinese and Indian trading networks, and in the 14th century was an exporter of aromatic sandalwood, slaves, honey, and wax.

A good primary source for this question would be Peter Beresford Ellis' *Eyewitness to Irish History* which presents, amongst other things, the majority of the Penal Laws which affected Catholics and non-Anglicans alike for the majority of the time they were in effect. Catholics, Non-Conformists (Calvinists), and other... | were the british as cruel to the irish as they're depicted in the wind that shakes the barley? | <P> and men were forcibly removed from Ireland and sent to Bermuda and Barbados as indentured servants. Laws that restricted the rights of Irish Catholics The Irish potato famine was due in part to Anti-Catholic laws. In the 17th and 18th centuries, Irish Catholics had been prohibited by the penal laws from purchasing ... |
The dress codes vary from department to department and have been evolving for a long time. Most officers I know now (pretty high number, nature of my job) favor all black boots on duty.

The partition of Carolingian Empire was finally settled in 843 by and between Louis the Pious' three sons in the Treaty of Verdun. After the Treaty of Verdun (843–... |
The theoretical minimum mass a star needs to undergo nuclear fusion (i.e. to actually be a "star") is about 75 times the mass of Jupiter. Neptune is about 5% of Jupiter's mass, so we'd be increasing Jupiter from 1 "Jupiter mass" to 1.05 "Jupiter masses" - still way below what we need. | jupiter is sometimes referred to as a failed star, too small to achieve nuclear fusion. if a neptune sized planet crashed into jupiter would it be big enough to be a star then and give us a small second star in our solar system? | <P> masses. Jupiter would need to be about 75 times as massive to fuse hydrogen and become a star. Mass composition The majority of Jupiter's mass is hydrogen and helium. These two elements make up more than 87% of the total mass of Jupiter. The total mass of heavy elements other than hydrogen and helium in the planet ... |
In most parts of the world suicide is legal, the only reason (in most places) that assisted suicide is illegal is because it's so difficult to put in place safeguards to prevent people from bumping off their ill relatives and then pocketing their cash safe in the knowledge that the euthanasia laws will protect them. | why do we have the right to life but not the right to death? | <P> labels as euphemisms and use the term "assisted suicide."
Controversy concerning the legalization of this practice typically arises from concerns regarding its intersection with manipulative circumstances or family members; inaccurate prognoses, the accuracy death certificates, unequal access to healthcare, financi... |
I assume you're referring to the submarine crewed by Masaharu Yokoyama and Samada Ueda, the M-16. It was never found and can safely be presumed to have been lost at sea somehow. It was last heard from at 10:41 PM. The last radio message was "success, success, success", so it's possible that the sub had penetrated the h... | what happened to the crew of the 5th japanese midget submarine at pearl harbor? | <P> and Yellow Sea areas. On 24 June, southwest of Kagoshima, the submarine contacted a convoy of six large ships guarded by 16 escorts.

Fluoride ions bind to enamel and turn hydroxyapatite into fluoroapatite. Fluoroapatite is much more resilient to acids and a low pH environment. Therefore bacteria cannot thrive and demineralize the tooth. | how does "restoring anticavity fluoride rinse" work? | <P> ocean and other water sources. The recommended dosage of fluoride in drinking water does not depend on air temperature. Fluoride catalyzes the diffusion of calcium and phosphate into the tooth surface, which in turn remineralizes the crystalline structures in a dental cavity. The remineralized tooth surfaces contai... |
I'm no neuroscientist, but I took a couple related courses in college. The general principle is called "synaptic plasticity" which basically means that transmission of signals within your brain strengthens or weakens over time as a function of activity. A "synapse" is the connection between two neurons through which el... | how does using your brain make it stronger? | <P> Homeostatic plasticity In neuroscience, homeostatic plasticity refers to the capacity of neurons to regulate their own excitability relative to network activity, a compensatory adjustment that occurs over the timescale of days. Synaptic scaling has been proposed as a potential mechanism of homeostatic plasticity.

Nice video. One point worth noting is that Schroedinger put forth his 'cat' thought experiment in order to demonstrate the preposterousness of quantum theory. It must have irked him that it ended up becoming the image to explain it. | zeno's paradox, the grandfather paradox, searle's chinese room, hilbert's hotel, einstein's twin paradox and schrodinger's cat all explained like you're 5 (youtube link) | <P> Schrödinger's cat Origin and motivation Schrödinger intended his thought experiment as a discussion of the EPR article—named after its authors Einstein, Podolsky, and Rosen—in 1935. The EPR article highlighted the counterintuitive nature of quantum superpositions, in which a quantum system such as an atom or photon... |
In the 50's switchblades became associated with criminals due their portrayal in films and television. Greasers, mobsters and other thugs were commonly seen carrying them and it led to a public scare and the subsequent passing of the USA Switchblade Act of 1958. | why are switchblades illegal? | <P> folded and locked in the closed position.
During the 1950s, US newspapers as well as the tabloid press promoted the image of a new violent crime wave caused by young male delinquents with a stiletto switchblade or flick knife, based mostly on anecdotal evidence. In 1954, Democratic Rep. James J. Delaney of New York... |

There are a couple of steps missing in there from "in a binary" to "fast rotation". Most neutron stars/pulsars are "born" with a spin period much faster than a second; the Crab has a 33 ms period and we know it was born in 1054 AD. Since they are emitting radiation in the form of a beam, they lose energy, and as they d... | why does a neutron star spin faster when it is part of a binary system? | <P> pulsars) and X-ray pulsars exhibit very different spin behaviors and have different mechanisms producing their characteristic pulses although it is accepted that both kinds of pulsar are manifestations of a rotating magnetized neutron star. The rotation cycle of the neutron star in both cases is identified with the... |
That's probably because Congress does not allow for funding of research into pretty much anything related to gun violence. However, we can look at other countries to attempt to draw conclusions. In Australia, they've gotten rid of many guns and found that suicide rates plummeted: . The idea being that many suicides are... | do gun waiting periods effect suicide rates? | <P> 2013, and suicides account for 63% of all firearm-related deaths. A 2012 review by researchers at the Harvard School of Public Health found that in the United States, the percent of suicide attempts that prove fatal is "strongly related to the availability of household firearms."

He didn't know it was The One Ring - it was thought to be destroyed. In The Hobbit the ring was nothing special (other than the invisibility), and in the Lord of the Rings books it took Gandalf 17 years from Bilbo's farewell party to discover that it was in fact Sauron's ring. | if gandalf knew bilbo has the ring, why did he let him keep it? | <P> the Ring. Eventually, Gandalf was able to determine the evil presence in Dol Guldur was indeed Sauron. Gandalf reported back to the White Council, but Saruman dissuaded them from moving against Sauron. Only when he learned the One Ring may be in the vicinity of the Gladden Fields did Saruman agree to attack Sauron,... |

So contrary to Rothammer (as discussed in u/Dondville) Marquet et al argue that the Chinchorros lead a less hierarchical lifestyle and that mummification isn't tied to status.

Many times monasteries and churches were built on land which was donated to the church by a king; so it was a case of "take what you get".
