What were the strong points of supply or strategy for the German army in WWII?
[ "For supply, the german rail system was quite resilient to Allied bombing. They were short on triangular junctions, but were able to repair most traffic blockages in short order. Specialized units were created for such work, and manpower was also requisitioned from local sources. Only at the very end of the war did German train service break down, and this was despite the paltry resources allocated to its defense or expansion. Christian Wolmar covers this in depth in *Engines of War*." ]

Caligula got his nickname from "little boots" (IE "Caligula" in latin) he wore as a child as part of a soldier costume he wore while accompanying his father on campaign in Germania. how unusual was it for a Roman general to take his young children on campaign with him?
[ "Not an answer, but a question to add onto this, did the Roman Legion have a series of camp followers? What was life like for these people?" ]
[ "I GOT THIS! In ancient rome, generals weren't allowed to march their troops into the city armed for fear that they would overthrow the goverment. When a particularly impressive and popular general had some great conquest the city would grant him \"Freedom of the city\" which effectively allowed him to bring his troops into the city in a parade or something along those lines. It was a sign that meant \"you're trusted and receive extra freedom because you have proven yourself an ally of the city\". The \"Freedom of the city\" gradually evolved into the ceremony we now label the giving of the \"keys of the city\" Edit: Source demanded, this generally should cover it: _URL_0_" ]

My grandmother inherited a huge amount of historical artifacts, from many different countries and continents and time periods. How do I proceed to help her figure out what to do with all of it?
[ "Any possible answer would depend entirely on what types of artifacts. In other words, if she's incredibly wealthy and has a vast collection of ancient Greco-Roman statuary acquired through quasi-legal means, the answer would be *entirely* different than if she has a salt-and-pepper shaker set that (possibly) at one point was in the possession of Grover Cleveland. Most likely would be printed documents of some sort? If so, again, it entirely depends on what sorts of artifacts." ]
[ "Please don't throw them away! A massive problem for historians trying to study the day to day lives of people outside the ruling classes of society is the lack of written documents concerning their lives. The problem is, as you have said, that people regard these letters as superfluous due to their content and don't bother preserving them or just throw them away. This leads to a shortage of actual primary sources that we can use to find out about the day to day lives of ordinary people. Letters between ordinary people are a useful way of finding out about how they lived, what things were of greatest concern to them (usually mentioned frequently in letters or often at the beginning) and what relationships they had. It might be worth trying to find someone who can do a proper transcription and translation and give you a better idea of what the letters say. I'm sure future generations of your family will be fascinated to read about their ancestors lives and to have such a physical link." ]

What became of the sword that was used to execute Anne Boleyn?
[ "I don't know what happened to the sword, and in my readings I have not come across any accounts of anyone who claims to know. (So if someone does know, I would be quite interested myself.) However, for Anne Boleyn's execution, a renowned swordsman from the continent was brought over for the execution. This was seen as a sign of \"mercy\" for her. It was merciful because he was very skillful at his job, meaning he could sever the head with one motion and therefore minimize pain. So because it was a private executioner who brought his own sword, my assumption is that the sword would have stayed in his possession and been used for other jobs he was hired for. It likely stayed in his family's possession until it was lost to history." ]

What does it mean when a ruler conquers lands? For example, when leaders expanded their empires, did they kill the indiginous people or simply gain power through taxation?

[ "\"Conquer\" is a loose word, he subjugated local kings and warlords who governed large territories. So you go attack the king in his capital, you defeat him, and you make him pay tribute to you. That is what conquered means. You don't go through each town and village and fight throughout the entire territory. Once your forces move on and the local king feels relatively safe, he stops paying tribute and becomes independent once again. This isn't to minimize Alexander's accomplishments, it's just to describe and contextualize his empire." ]

Did Saddam Hussein try to nationalize his oil before 9/11?
[ "Iraq nationalised its oil industry in 1972 and joined in the 1973-74 Arab oil embargo against the US and selected allies (there'd also been an earlier rather ineffectual one in 1967).

A regime the US did not like: there was mutual enmity between the US and Iraq since the 1991 Persian Gulf War 3. The Iraqi regime was weak: over a decade of harsh US-led sanctions had crippled the Iraqi economy/military, starved a million Iraqis to death, and turned it into a non-state 4. Iraqi exiles convinced Americans that the invasion/occupation of Iraq would be easy: characters, like Ahmad Chalabi, insisted that US troops would be welcomed with trails of rose petals and jubilant cheers 5. 9/11: the US was in a hysterical climate from the WTC attacks and could be convinced of just about anything.

His flight was intercepted by a flight of P-38s and his plane was shot down and he was killed. The pilots of the P-38s were not told who they were after." ]
[ "There was not much backlash. 1) Killing civilians during total war (the kind of war we were in) is not considered a crime or atrocity. During total war the entire society of the nations involved are a part of the war. Civilians make the weapons, grow the food, and are the replacement troops. They are not innocent, they are just low priority targets. 2) The Cities were legitimate military targets. One held major weapons manufacturing centers, a supply depot, a troop deployment point, and a military headquarters. The Other held a major shipyard, a portion of the Japanese fleet, and weapons manufacturing. 3) The two bombs killed fewer civilians than the traditional bombing methods used against larger cities such as Tokyo were killing. Edit: Additionally we won. The winner is the one that dictates if misdeeds were carried out during a war generally. Or at least that is how it has been for most of history." ]

Did massive shoulder armor as commonly seen in games and movies (sometimes with huge spikes protruding forth and thick elaborate plating) really serve to protect the warriors of old? Or are they impractical and cumbersome in reality?
[ "[That kind of shoulder guards](_URL_0_) never existed in real life. Shoulder plates serve two primary functions; 1) To protect your shoulders without restricting movement. 2) To protect your neck from direct blows and glancing blows. For the second reason mentioned here you sometimes see a [\"ridge\" along the upper part of the shoulder plate](_URL_1_). Adding things like spikes and shoulder guards several inches thick never existed because: 1) Spikes fill no function other than weakening the armor and adding weight. 2) Massively thick plates add lots of weight, restrict movement and offer no additional protection. Why add several centimeters of heavy steel where a few milimeters will do the same job?" ]
[ "I like most of the answers below, especially m4nu, but there's one big thing no one's mentioning: Armor. As technology progressed, muskets made armor utterly useless. Then, when hand to hand combat did occur, there was no need for a sword so heavy it would break a man's ribs through iron, just something to stab him with would do just fine.

How did an hour become an hour?
[ "This goes back to Babylon (and probably before), which used a (sort of) base 60 system to simplify the arithmetic. It's the same reason we have 360 degrees in a circle: there are a large number of convenient factors that make the maths simpler. All sorts of things divide neatly into it. The same holds for 12. An hour was long defined (in Europe anyway) in two different ways: as 1/12 of the day and 1/12 of the night, which caused serious problems (the hour would have different lengths throughout the year), and also as a set unit of time roughly equal to the above. The latter was necessitated by the development of certain mechanical measuring devices such as water clocks, etc, which wouldn't vary with the seasons. This problem wouldn't really disappear until mechanical timekeeping became the standard." ]

Drunk Americans today enjoy gorging on wings, pizza, and other bar/drunk foods. However, these foods are quite new. What did drunk Americans eat before deep fryers and pizza?
[ "You may want to x-post this over at /r/AskFoodHistorians" ]
[ "In order for a food to become popular in an area, you need: * access to ingredients * skill to prepare it * demand * lack of alternatives For example, I was visiting a friend in Australia, and wanted to cook Mexican food for him. The supermarket had tortilla chips and hot sauce. So unless I wanted to whip up tortillas from scratch, I was out of luck. Whereas here in the western US, I (or a restaurant owner) can head down to the local panaderia can get fresh, cheap, authentic tortillas whenever I want. Also be aware of the role lack of alternatives plays. Local cuisine is often born of necessity, solving some problem or avoiding scarcity. Many Asian foods come from lack of meat, Jewish foods work with strict dietary restrictions, and Southern soul food is based largely on what was leftover to slaves after their owners ate all the good stuff. Other communities, when not faced with these restrictions often bastardize recipes (e.g. beef vindaloo) to include what is locally available." ]

Did countries outside of Europe try to colonize/participate in imperialism?
[ "Huh. That is actually a pretty interesting question. When the Roman Empire conquered Germania and Britain, for example, does that count as \"colonialism\"? When a smaller power buys off the bigger power with tributes (e.g., when the Malacca sultanate sends tribute to the Emperor of China in the 15th century, or the Malay states doing the same to Siam two centuries later), can that be considered at least proto-colonialism?" ]
[ "The end game would have been pretty much Italy forming a new \"Roman Empire\" with colonies in North Africa, Middle east, and territory in the Balkans. Japan was trying to create a \"Asian Co-Prosperity Sphere\" where their idea was basically to take over China, Korea, and South East Asia and modernize them (read: Japanize them) to compete with the Europeans. Germany was basically going to conquer Eastern Europe and try to settle the land with Germans and then Germanize/kill/relocate the Slavs living there. Hitler didn't really want to conquer good Germanic people like the Dutch, Scandinavians and Brits, he actually thought they would join him. So most likely there would have been Fascist governments put up throughout the rest of Europe." ]

BS History w/concentration in "Applied & Public History"
[ "If you want to do museum work or some other type of public history, I would advise you to do the B.S. in history with the applied and public history concentration. If you are interested in traditional academic history, especially someday a PhD program, do the traditional B.A. degree. Sometimes there is not a lot of difference between a B.A. and a B.S., but most of the time the distinction is that a B.A. requires substantial foreign language coursework, as Eistean notes. It might seem like skipping the foreign language is a good idea, but that would actually be a mistake if you want to go on to a graduate degree. Graduate programs generally require reading proficiency in multiple languages for any field except American history, and many require at least one even for Americanists." ]

Why was the Golden Horde called like this?

Was the Boshin War fought over a hypocrisy?
[ "It's important to keep in mind that situations changed quickly. Both the leaders of the Bakufu and the leaders of the New Government were very clear that they needed to westernize. And both sides had imported western arms and called for western experts. Due to the failed action against western powers and the lost of of high political support due to the death of Emperor Kōmei, *jōi* was basically dead (though they still hoped to renegotiate the unequal treaties). The fighting was due to a disagreement on who was to lead the new government (the Bakufu had *voluntarily* ended, though it might have been restored had the fighting gone the other way, we'll never know). That said, considerable number of the rank-and-file of the men on the New Government side thought they were betrayed by their leaders, which contributed to the early-Meiji rebellions.

Would the type of gun used to assassinate Lincoln have a shell?

The bullet -- a round ball -- would be forced down the barrel after a powder charge was poured, and a percussion cap affixed to the nipple.

Moreover, even if there were a cartridge I have a very hard time picturing *any* cartridge having enough kinetic energy to puncture anything but wet tissue paper.

Does anyone have any good resources on the troop movements of the German Imperial Army circa 1916 on the division level or access to regimental histories? Trying to solve a family mystery.
[ "I suspect the confusion is between that of the 54th Infantry Division (which fought in Verdun) and the 54th Infantry Regiment (which fought in the Baltics) in 1916. The 54th Infantry Regiment was part of the 36th Reserve Division, which was curiously seeing action in both Ukraine and near Riga around this time. It is likely that the division was temporarily split (probably due to the Brusilov Offensive, where many German units were sent as reinforcements to stop the Russian attack in West Ukraine) and your uncle may have remained in the Riga area, which was also where the 87th Infantry Division was serving at the time. If the main divisional HQ and rear area units had moved to Ukraine as well, they would likely rely on the postage of whichever nearby divisional post office was available, which in this case would have been that of the 87th." ]

A user says some things mostly about the influence of Jews on the start and course of WW 1 + 2. Is this user correct, or simply taking things out of context?

Similarly, examining the logic and arguments used to draw the conclusion and seeing where it goes right or wrong takes a lot of time and effort. In general, it's not really worth it to make such an effort.

What was the Green Army in the Russian Civil War and what were they fighting for?
[ "The Green Armies weren't an organised force in the same way that the Reds and Whites were during the Russian Civil War, rather it's a term used to describe a number of peasant groups that resisted the Reds in defence of their communities and regions.

In response to this forced requisitioning of supplies, Green armies comprised of peasant farmers sprung up to protect their communities and livelihoods. The Green armies were not officially involved in the political scene of revolutionary Russia, though their members and actions were anti-communist by action rather than ideology.

The Carolingian's main problem was the Saxons, a decidedly different culture then the Catholic Franks. The Capitulary for Saxony tells us that the Carolingian's created wholly new laws, just for the Saxons. Most of these laws were related to religion, thus one can observe that one of the ways of ensuring the empire did not revolt was to try and assimilate the different cultures within your empire.

Tuesday Trivia | Pets and Other Animals
[ "It's not a widely known thing, but Tenochtitlan kept a rather extensive zoo of animals as well as botanical gardens. There is some recent evidence, however, that Teotihuacan may have also had a zoo long before the Mexica made one. It makes me wonder whether the zoo practice was taken up by the Mexica because the practice of having a zoo was passed on from Teotihuacan to other intermediaries like the Toltec before Tenochtitlan made theirs. However, Teotihuacan may have just kept animals in captivity for future sacrifice and since you don't want your sacrifices to die before you need them than you would have to feed them. I don't think anyone has identified a structure at Teotihuacan and could say with certainty that it was a zoo and not something else. But then, I'm also not aware that they've identified Tenochtitlan's zoo since it was either destroyed in the centuries after the Conquest or is buried under Mexico City." ]

14/88 is a phrase used by neo-nazis today, but did the number 88 hold any significance to nazis during the 1940s?
[ "It didn't have any significance. 88 stands for Heil Hitler, Heil Hitler wasn't a banned slogan in Nazi Germany. It started in the Neonazi scene (I'm not sure about the date but I am very sure that it wasn't directly after the war) as a code as it was banned by the \"Wiederbetätigungsgesetz\" (the nazism ban law). So it only started to get used as a way to circumvent anti-nazi laws *after* the war. As a source, Austrian DÖW (Documentation archive of Austrian resistance) works also on modern right wing extremism and they say that too. Online it is only in German." ]

When did nations begin to regularly levy taxes?
[ "Can you winnow this question down more, whether geographically, temporally or both?

Late medieval European feudal taxation? Or specifically state taxation of the early modern period? Taxation in coin, or taxation in kind? Please be more specific." ]

Is there a historical reason for Canadian's having a polite culture?
[ "Difficult question to answer since it's so ambiguous. One explanation that might contribute to that idea is the general character of Ontario, which is where I suspect this stereotype is derived. Up until the 1960s, Ontario was fairly British, Protestant and Conservative. As in, you couldn't drink on Sunday, and you bought liquor from the LCBO in brown bags so as not to 'offend' people. This culture produced Ontarians that were (stereotypically) quiet, demure, polite, etc. Of course by no means was all of the province like that, but probably the urban elite of Toronto with whom most Americans would have interacted could have been at the root of this idea. Imagine that British stiff upper lip idea with a conservative Protestantism, minus the powerful British Empire identity... And you might get a polite English Canadians. Again, this question is difficult to answer as (as far as I know) there aren't exactly sources pointing to the cause. So take mine with a grain of salt." ]

Did the Germans count on being able to use the Czech tanks?
[ "Opening a can of worms here. There was actually no such thing as the Blitzkrieg so it'd be a bit hard for something to be an essential part of it. Blitzkrieg was more of a media term to explain things that they didn't understand and the whole idea that it was some well developed doctrinal way of waging war by the Germans just doesn't stand up to scrutiny. That being said, the Germans did make a habit of appropriating captured enemy equipment, reddesignating with German names, and then using them. However, the Germans expected to have a few more years to prepare for a major war and so they expected to have more of their Panzerkampfwagen III and IVs, and possible even some heavy tanks since the Tiger had been in development since the late 1930s, by then instead of mostly the Is and IIs they went to war with, supplemented with captured Czech equipment." ]
[ "For a bunch of reasons: * It would have been difficult to drag their tanks in there because Switzerland is, mostly, surrounded by mountains. Mountain fighting alone is pretty deadly but one of the major advantages that Germany had early in the war was the speed of their tank attacks. * Swiss had a conscription process so every man was a trained soldier with their weapons at home. * The Swiss had set up every bridge and tunnel to be destroyed in case of attack. * It's not a fun air war in Switzerland. Crossing the alps requires lighter loads. * There isn't a lot of military benefit in owning Switzerland. The Swiss really couldn't go on the offensive and Germany had all of the surrounding land. * By the time that the Germans were operationally ready to attack Switzerland they were already fighting on both sides of Europe. They really didn't want a launching site in the middle." ]

How much did the SS/Einsatzgruppen collaborate with Unit 731?
[ "No, or at least not to my knowledge. The Axis Pact was pretty much a hollow alliance and proved strategically worthless for Japan and Germany. Geographic distance and logistics were one major difficulty. But you actually chose the wrong country. The more interesting and relevant country here is not Nazi Germany but the United States. After the war, the US military granted Unit 731 doctors immunity from war crimes prosecution in exchange for the biological and chemical warfare data extracted from human experimentation. So it was the US, not Germany, who ultimately benefited from Unit 731 research." ]

How did Japan's modern censorship laws come to be?
[ "I posted about this on Reddit 5 years ago: _URL_0_ I wouldn't use that snarky tone today, but basically, yes, censorship laws were created in response to heavy criticism from Christians about Japanese \"barbarism\". Christian missionaries organized international campaigns against geisha, sake, mixed bathing, and pornography from the 1870s up until literally the day of the Pearl Harbor attacks, when they were all peacefully sent home. (It's kind of amazing to me that Japan was tolerating foreign missionaries up through 1941, but fascism doesn't necessarily mean imitating Germany, I guess.) As for why they continue to exist, well, that response to Christian morality became embedded in the culture and now people think it's an essential part of avoiding obscenity.

Philanthropy in Ancient Rome
[ "It can only be loosely called philanthropy, as capitalist enterprise and the idea of charitable institutions did not and could not exist at that time. & #x200B; Simply and briefly put, Roman society was held together by the patron and client bond, in which a patron would serve as a kind of legal and material guardian for clients, who in return provided services. & #x200B; Providing the community with impressive buildings or circuses was a way for a patron to gain more clients and prestige. In many ways this is like philanthropy today, but perhaps not totally. For instance, the Gates foundation is more of a way for Bill Gates to liquidate his vast fortunes and do the greatest possible good with it. I think this would be quite strange to a Roman and was not something I've ever heard of them practicing." ]

Why has the legal age to drink in the United States never been overturned by the supreme court? Being that the draft is 18 it seems like it would be a inevitable eventuality...
[ "actually it is legal for 18 year olds to drink under federal law it is the state that sets your drinking age. Its a little known fact but the drinking age is enforced via the funding of interstate highways. If a state lowers its drinking age in any county to below 21 the Federal government will stop assisting them with interstate highway funding meaning basically the entire states roads would degrade to the point of being unusable. Just to note the legal drinking age in New Orleans was 18 up till when Katrina hit, after that they didnt have the funding to rebuild the highways without raising the drinking age and it hasnt gone back down since." ]
[ "The drinking age was more variable in the past in the US, as it used to be a state decision, though, generally it was 18. In 1984, a law was passed, the effectively changed the drinking age to 21, everywhere and took power from the states (technically its a more complicated than that, but effectively, its all the same). So why was it changed? Well a lot of groups, such as MADD (Mothers Against Drunk Driving) hugely lobbied for the age to change, and won. Guns were traditionally 18, though in some states, buying a handgun is 21 (long guns are 18 still usually though). There has never been serious realities of changing this, and is still mostly a state thing. Lastly. These are not the same and should not be compared." ]

Qing reaction to the Manila massacre of 1740
[ "While /u/PangeranDipanagara has rightly pointed out that the Qing response was not going to be an immediate turn to war, I think OP is heavily underselling Qing *perceptions* of naval power. Whist in objective terms the Qing navy was not particularly powerful, the last times that Chinese fleets had fought European ones they were generally successful – Zheng Zhilong against the Dutch at Liaoluo Bay in 1633; Koxinga against the Dutch in Taiwan in 1661-2. As of yet there was no clear indication that a Chinese fleet, despite known technological inadequacies, could not deal with a European one. To add a more relevant bit about restriction of trade, even on the eve of the First Opium War many in the Qing government did genuinely believe they could hold Western countries hostage through embargoes. Lin Zexu, for example, believed that the cutting of tea and rhubarb exports to Britain would lead to mass fatal constipation and insinuated as much in his open letter to Queen Victoria in 1839." ]

What pre-gunpowder weapon had the longest effective range?
[ "In terms of hand-held weaponry, the bow and arrow had the longest effective range. At the height of the English Longbow during the reign of Edward III, the average professional archer was said to have been able to shoot a distance of 365 metres (399 yards). That claim is a bit contentious though, but no practice range was allowed to be less than 200 metres (220 yards) during the reign of Henry VIII. The effective range would be different in a battle situation though, as while the archer might not be able to hit an individual soldier, he could hit someone in a charging army. The ballista used by the Roman Empire had a range of around 460 metres (500 yards). There are accounts from soldiers of ballista operators being able to 'snipe' or pick off single targets. There are also tales of charging rows of soldiers being pinned together by a single bolt." ]
[ "I mainly deal with European history and was going to chime in on the firearms, but there is just no way to generalize without being more specific. For example, the term \"musket\" covers weapons used from the 13th century up until the 19th century, and rifles are still used today. A Ming Dynasty musket and a Napoleonic Era musket are going to be vastly different weapons. Lastly, what does \"damage\" mean when it comes to deadly weapons? Being hit by anything from a bullet to a thrown rock could either kill you or deflect off your skull and do only superficial damage. How do you rate armor piercing when you have thousands of years of armor to compare it to? I don't know how to pin down the era you are trying to replicate when you have weapons like slings and Pilum that were only rarely used in the last 1500 years next to rifles, a rather modern invention only really proliferated in the post-Napoleonic era." ]

[ "> Did they count down the years at the time, like BC They couldn't have.

For example the Mayans (of 2012 fame) had a calendar based on counting the days since 'creation', which happens to be August 11, 3114 BC on our modern calendars. So for example August 31, 3114 BC to a Mayan would be day 20 and December 21, 2012 is day 1,872,000. Other cultures based their years on the reign of their current monarch. So a date may be recorded as March 15, in the 3rd year of King Derp; or something similar. It's this system which was used in our current calendar, using the birth of Christ instead of the rise of a monarch." ]

Was the California Gold Rush of 1848 generally positive or negative for America?
[ "This is a bit of a broad question, but generally there are two major, long term effects of the Gold Rush--the rapid development of California, and the beginning of immigration of East Asia, particularly China. Both of these have been fantastic for the US. So long term, I think there is no question that it was good. However, I would be quite interested to hear of the short term economic effects. The population in 1850 was something like thirty million, and a few hundred thousand people suddenly going to the other side of the country might have had a profound impact. Comparative evidence suggests it would be positive, because it would decrease the labor surplus. It was not generally successful people who moved.

Until then only China, Russia, the US, the UK, and France may possess nuclear weapons and they must make gradual efforts toward dismantling their arsenals. India thinks this is unfair, because China has them, and China acts fairly aggressively towards India sometimes, meaning India wants nuclear weapons to defend themselves. Pakistan also has disputes with India and felt threatened that India had them, so they created their own. Signing the treaty means they can't have them anymore, so they refuse." ]

Help understanding the study of History
[ "I generally ask myself, \"would I be able to teach a lesson on this?\", or \"would I be able to explain these key concepts clearly and confidently to someone?\" It's also a good habit to take notes on texts you're reading, to actually summarise and rewrite what you're reading, rather than just try and take it in. Write on four-by-six inch index cards, for example. Don't just read the book for hours on end - I generally don't read non stop for more than one hour. If you're more interested in this, Barbara Tuchman has written a book called *Practising History* (1983) which has information on writing, note-taking and more. Some of my favourite quotes from that book: \"*The most important thing about research is to know when to stop...research is endlessly seductive; writing is hard work.*\" \"*Distillation is selection, and selection, as I am hardly the first to affirm, is the essence of writing history.*\"" ]

How did the people of the Soviet Union view America pulling out of Vietnam? Was it a victory for Soviet morale?
[ "Happy the war was over, decreasing the risk for direct military action between USA and USSR, especially nuclear. Opening up for thawing of relations between the two. Pride in USSR's role as a communicator and at times unofficial mediator in the drawn out peace process ('63-'73). Some pride in the little nation that could somewhat stand up to massive western imperialism. Troubled by the political ground won by USSR's main competitor in SEA - China. That's the general idea, hard to say how it was practically disseminated in the general public. *Sources: Ilya V. Gaiduk - The Soviet Union and the Vietnam War. Confronting Vietnam: Soviet Policy toward the Indochina Conflict.*" ]
[ "I think the US believed in the domino effect at the time, that if one country became communist, more and more countries would adopt it. It also served as a proxy war with russia IIRC." ]

Is it true that the USSR did not teach the Big Bang theory because they thought it had theistic undertones?
[ "I thought it was a good question, so I checked Russian Wikipedia and it mentions [this](_URL_0_) and cites some sources (last paragraph of the Критика Теории) To rephrase, it wasn't a theism per se, the problem was that eternity and infinity of the Universe was an established marxist dogma. Thinking otherwise would lead to some sort of idealistic thinking, including, but not limited to theism. So they found an interesting solution - it was accepted that Big Bang was a start of the Observable Universe, while the Universe (or matter in a broad sense) is deemed as something larger, infinite and eternal. You can think of it in this way - the Observable Universe with its time and size limits was left to physicists, while philosophers kept theirs infinite and eternal marxist Universe to themselves. Doublethink wasn't that uncommon in the USSR." ]

CIA Capabilities in the 1950-60s

[ "The Chinese were equipped with Soviet made MiG-15 fighters. They outclassed everything that the UN could put into the air and it stayed that way largely until the introduction of the North American Sabre. While the Sabre closed the performance gap, it was by no means a superior aircraft.

Did people shorten years before the 20th century? (Ex: '97, back in '08)
[ "The \"Crime of '73\" springs to mind - late 19th-century I think, but I don't know if it was used as early as the 1870s. And of course California had its '49ers, a still more novel form. Before then Scotland's Jacobite rebellions were known as \"the '15\" and \"the '45\", perhaps not long after the latter though again early mentions are elusive." ]

What is the longest war in history?
[ "You would need to define \"war\" for the purposes of longest here. Do you mean the longest continuous active conflict between the same belligerents? Or perhaps the longest technical state of war featuring an armistice or prolonged truce (e.g., the Korean War)? Or perhaps the longest period of war featuring the same belligerents, but with some interspersed times of peace between them (e.g., the Hundred Years' War)? You would also maybe want to take into consideration \"wars\" in which only a single participant continually fought multiple, sequential enemies, in which case virtually the entirety of the existence of Classical Rome might be considered. You would also perhaps want to isolate for \"longest wars\" relative to the existence of the political entities involved therein. The Democratic People's Republic of Korea has been in a continual state of war for its entire existence, for example. Interesting question, but I think it requires a bit more definition." ]

When I think or imagine, it actually feels like that is happening inside my head. Prior to the notion that the brain is responsible for thought, did ancient people "feel" their thoughts elsewhere in the body?
[ "I used to be versed enough in the subject to confidently post an extended answer on the question, but the short answer is Yes! Consider how inert the mind feels compared to other parts of the body when undergoing stress or intense emotion (Heart, liver, gut/intestines). Different aspects of lived experience, such as religious rapture, inspiration, and fear were tied to different parts of the body, which would be felt as most active during these times. Of course the correlation between lived internal experience and organs varied from culture to culture. This also extended to the bodily origin of thoughts. [Here](_URL_0_) is a fascinating read on the subject. In the culture analyzed by this book, thoughts are considered to originate in the liver, and drift their way up into the head." ]
[ "One dream theory states that our upper brains (cerebrum) receive random signals from the lower brain (brain stem, cerebellum etc.) and the upper brain tries to make sense of them. It takes the data, interprets it and then experiences what that interpretation states should be experienced. That isn't to say that you can't feel out of place in a dream. I sure have. Plenty of my dreams have freaked me out even whilst in the dream." ]
