What is a "manic pixie dream girl" and why is Twitter so angry about them? | Think of Jersey Girl, or Garden State. The girl is cute but sort of standard, somehow. Not gorgeous, usually brunette, not hugely busty, but sexy-fun. And she's got problems, of course she's up, she's down, she's happy but she's got a secret sadness. She takes the hero and pulls him out of whatever his depression is, u... |
Why can't we remember dreams very well? | I have a subquestion to this. Why can I remember last night's dream better before I go to sleep rather than after I wake up? |
Why isn't the Concorde used anymore? | It was too expensive to maintain as a regular service, and the customer base never really recovered after the crash and 9/11, and following that the general introduction of low-cost airlines. As an aircraft, Concorde required a massive amount of inspection, QAQC and maintenance compared to standard aircraft. Even just ... |
What is the science behind saunas? I thought heat was bad for your skin. | It is because this kind of heat helps blood flow and this helps repair cells in your body. Too much heat from the sun can cause cancer but this heat works differently than sauna heat. Sauna heat can cause dehydration, so that can be bad if you don't drink enough water to balance the sweat you are losing. |
I couldn't find anything. Can someone explain to me what a 'Default' means? | If your talking about America 'defaulting' on it's loans it means America can't pay it's bills on time. It's like if your mom and dad can't pay their electricity bill the power company doesn't like it. Countries like the USA have bills to pay too and at the moment the country is broke UNLESS Congress approves to raise ... |
Why do retail prices end in .97 or .99? | In your subconscious mind, when you see **4**9,99 instead of **5**0,00, it sort of helps create the illusion the item you see it isn't as expensive as other similar items. Say you see an IPhone that costs 799,it kinda makes a difference when you put an 8 in front.. So the larger the amount, the more effective the illus... |
Why did technology improve so exponentially quickly within the last century? | I'm no expert on the matter, but if you're looking for one real key, I would say communication. For example, when people had to walk around just telling each other new stuff, technology spread really slowly, so only those who were aware of the new tech could expound on it. Then you get a shock like writing. Now people ... |
There Are Thousands Of Uncharted And Unclaimed Islands In The Pacific Ocean. So Why Do You Have To Buy An Island? What Is Stopping Me From Simply Claiming One As My Own? | In the end, there are pretty much only three things that affect sovereignty: 1: Claim the territory 2: Defend the territory 3: Get other nations to recognize your claim Really only #s 1 and 2 are required, so long as you don't need to be able to travel outside your area of influence |
Why has Chris Christie become so popular of late and what has he done to become so loved? | He poked his finger in the eye of the Republican party last year when he praised Obama for his help/response on Hurricane Sandy. He tells Tea Party guys they are full of sh*t. He is perceived as being a blend of old fashioned Republican conservatism a without the scorced earth hatred of people who think differently tha... |
What exactly is seasonal depression? | I believe it's a combination of two things:- a deficit in vitamin D, this is needed to make serotonin in the brain. Too little serotonin is related to depression. Your body needs sunlight to make vitamin D.- short days, too much time spent in the dark, and also: inside can mess with your head. I'm not familiar with the... |
what is the ringing noise we hear when there's silence? | I always though it was Tinnitus. The human ear can hear between 20 hz and 20khz on average. The older we get the smaller that range becomes. I've heard that from damage to our ear drums and just getting older we lose certain frequencies that we can hear, and that you'll hear a high pitch frequency when the damage is ha... |
When the South Korean ferry MV Sewol capsized, why couldn't they cut through the hull to get into the ship? | When a ship is capsized, one thing that really helps it stay afloat are the air pockets trapped within. The air can't escape because one side blocked by water and the other side is blocked by the ship. If you cut through the hull, you might give the air an opening from which to escape, and sink the ship in the process. |
Why do people with poor vision instinctively squint their eyes? Why does this make their vision slightly more clear? | The act of squinting slightly reshapes the eyeball. This changes the focal point, sometime correcting an out of focus condition. It's important to understand that most folks who wear corrective lenses need them because the shape of the eye causes the incoming image to be focused either in front of or behind the retina,... |
What is Gluten and why do some people take a gluten free diet so seriously? What's it doing for them? | Gluten is a protein found in wheat and thus can be found in bread and many other products. For the majority of people, it causes no problems. However, those with Celiac disease are allergic to it and suffer damage to their intestines when eating gluten, thus they must avoid it. There's conflicting evidence that some pe... |
Explain like I'm 5 why children seem to have so much more energy than adults, or even old people. | It's actually our fault. We make sure our kids are active, well fed, and well rested and while doing that we usually forget to do them same for ourselves. Like right now my 2.5 & 4 year olds are jumping off chairs at 10pm I've been ready for bed since 7pm it's so incredibly frustrating ;) |
How do cellphones slow down "naturally" after 2 years or so? | The kind of battery technology we use right now, at least, is only good for a certain number of charges. Afterwards, it's capacity starts to drop, as does it's output. A lot of the time what people really need is a new battery. Most also use solid state memory, which also has a limited number of writes and rewrites bef... |
why cars' radio antennae are so much smaller than they were 20 years ago. | Its just a theory of mine, as yet untested by science, but I suggest that music was much better twenty years ago so the antennae had to be more robust. Todays weak crappy music isn't powerful enough to melt smaller antennae. |
How a non-shutterbug iPhone photographer like myself could snap the pics of space like I see on here. Some of you seem to be taking this pics while in space. | If you're talking about those cool photos of the Milky Way you see sometimes, people are generally driving out to the middle of nowhere and taking long exposure shots with a tripod mounted DSLR. |
Astronomers can zoom into pictures of our galaxy to see billions of stars very clearly. Why cant they zoom in to our closest solar systems and see the planets clearly? | Stars are huge & make lots of light. This makes them easy to see. Planets are tiny and only really reflect light back at their sun. This makes them very hard to see. Imagine you're at one end of a football field, it's pitch black & there's a light bulb at the other side. You're going to be able to see that pretty easil... |
How is the US women's soccer team so dominate while the men's team is so average? | My theory: In the US, athletically talented men can get recruited into lots of high-paying sports: football, baseball, basketball. There's less fame and fortune in soccer, so not many men pursue it. Because soccer is so popular in other countries, almost all of their male athletes try to become soccer stars. So other c... |
Why Wells Fargo won't fail due to their latest (assumed) illegal activity? | Simple. Don't bank with them. I haven't in decades. The actual harm to customers was only a couple of million dollars. That is a lot, but very small in comparison to the size of this company. |
Why does the American military still use the Humvee, every though it's outdated and there's better options? | I think /u/STR8_SHOOTER is right on the money. I would like to add that Oshkosh recently won the contract to build the humvee's replacement, the Joint Land Tactical Vehicle. [Source] . Though, that contract will go through at least one review and it will take time to cycle out the older vehicles. |
How does Disney Channel manage to stay on the air and be profitable for so long when all of the commercials shown on there advertise for upcoming Disney Channel shows? | I haven't seen this mentioned yet but Cable Companies pay Disney Channel fees for their content as well. Needless to say those fees are passed on to the end user.When I was a kid, Disney was a premium channel, like HBO. I remember getting excited for "free preview" weekends every so often. Then, I was even more excited... |
What allows a crankshaft to turn when engaged to a transmission that isn't turning? | A simple analogy for how an automatic moves is this: imagine you have a bowl of cereal resting on a 'lazy Susan'. The lazy Susan is like the wheels of the car. The bowl of cereal replaces a solid clutch. You drive the lazy Susan by stirring the cereal really really fast. Gravity on your car would be analogous to someon... |
What is the widely accepted hypothesis as to how the Egyptian pyramids were built? | _URL_1_ My favorite is the cement theory, but isn't widely accepted.I read an article describing the effects of water on flat sand like that and how it would assist in construction. In order to drag the huge carved blocks, if you dampen the sand before you drag the rock, it makes the trip much easier without the "givin... |
Why do house flies keep rubbing their "hands" together | Can't remember the source where I heard this, but one aspect to this behavior that I've heard is that they'll rub their head and body to clean them onto their hands, and then rub their hands to gather up the dirt for disposal. They'll keep going reflexively until they reach the right size dirt ball to call it quits.The... |
Why is FIFA considered corrupt? | The board is composed of 24 members. So to get the majority of votes just need the support of 13 people. But in 2010 two of those members were found in a scandal involving selling their votes for $800,000 USD. So now you are down to 22, you only need 12 people to bribe 12 people to support you that's not that hard if y... |
Why do shaving nicks hurt so much more than say the cut you receive when falling and scraping your knee? | I don't think this is universal I don't think they hurt more than a scraped knee at all my shaving cuts hurt for about 1 second when I actually cut them. By the end of the day they are healed. In contrast a scraped knee will usually take a week to heal. Meanwhile it hurts every time I forget about it and kneel on it.Wh... |
why the American government is having so much conflict with Iran. | Because we have a friend called Israel who doesn't want to see the US and Iran get along, because Israel will feel left out and jealous. |
Why are old ruins deep underground? | As time passes nature covers everything on land with dirt. Humans also build newer buildings on the ruins of older buildings. Today we would not think twice about demolishing a building from the 1950's then building something new on that lot, and previous generations of people felt the same way, demolishing older grand... |
Why are some tribes still preserved in a primitive state? | The answer to > Why are some tribes still preserved in a primitive state? ie why we don't contact them is because we know today the the common result is often devastating for the tribes. They likely know something about the outside word but choose to not contact it. To quote [Uncontacted peoples] > Uncontacted people, ... |
Can someone please explain the potential effects of raising the minimum wage to $15? | The immediate effect would be a notable, but temporary, spike in unemployment, as not every employer will be able to afford the wage spike, and not every employer who can afford it will do so. This is followed by the effect of increased demand by people who spend the most of their income. Suddenly, their income has dou... |
If every cell in the body is replaced within 7 years, how do we have memories that are older than 7? | This is asked frequently, and the answer is that it's simply a myth. Many types of cells turn over much faster than 7 years, like skin and blood cells. Others, like neurons, can last your entire life. |
The Basque independence movement. | For a good perspective on the Basque, and the roots of the independence movement, check out 'Basque History of the World' by Mark Kurlansky. Great book, great author. EDIT: You might want to have your Mom or Dad read this one too you, unless you're a particularly precocious five year old. It's got some bigger words in ... |
Why do people in the U.S. still vote for Democrats and Republicans? | As much as people complain, when it comes to election time, many people are happy voting for one of the two dominant parties. It's like Electronic Arts. People on r/gaming complain all the time about them, but when it comes down to it, they are willing to pay a lot of money to play their games.I think it ultimately com... |
Why do i get jittery and move around more when I have to pee really | your brain can actually lower the electrical threshold required for muscle activation when it 'wants' you to move. this diminishes the energy cost of muscle activation and, therefore, makes fulfillment of some nascent goal easier to achieve. this hypersensitivity happens in the fear response and other responses where t... |
A wheel is bound to the car by lug nuts, but how does an inflatable rubber tire stay bound to a wheel, especially under tremendous forces? | The shape of the wheel prevents the tire from falling off. Most car tires are inflated to a level around 30-35 pounds per square inch. That's a lot of force pushing against the lip on the wheel rim. That would have to be over-come on a significant portion of the rim to force the tire off. |
How do scat porn actors not get sick from eating all that feces? | Also, I doubt the CDC is actively getting involved in any way with the scat porn industry. If anything, they've probably published a statement or warning about the dangers of ingesting fecal matter and left it at that. |
Why does thinking make me physically tired but doesn't burn any calories? | _URL_0_ Note that reading burns about 1.5x the number of calories that watching TV does. They're both small amounts compared to physical activity, but the content of your thoughts will actually change your calorie consumption. |
The air we breath in is mostly Nitrogen. What happens to N when it enters our lungs? | N like Nothing, which it does inside our lungs other than taking up space and stop your lungs from killing you via oxygen poisoning. Wait what? Poisoned by oxygen? Yes that is a thing. And it doesn't happen because the air is mostly Nitrogen. |
How come I can see the flashing lights on an airplane but the light doesn't illuminate me? | The light you are seeing is reflected off dust and water droplets in the air. It is a very bright strobe light, designed to make the aircraft visible to other pilots. It is usually turned off when flying in clouds, because it would reflect off the clouds and blind the pilots. It's also usually switched off on the groun... |
why potato chip companies fill their bags with so much air and so little chip | Ever notice how the chips get crushed a lot more easily once you've opened the bag? The companies noticed that too, and decided to fill the bag with a special kind of air that not only helps keep the chips from getting crushed on the way to the store, but also helps keep them from getting stale. |
What is the actual mechanism of the stomach flu? | My understanding is that there is no such thing as a stomach flu and that it's simply a term used to describe gastroenteritis. It is not related to influenza. The influenza virus does not typically cause stomach and intestinal distress in adults. So you ate something bad that contained something like the norovirus that... |
Why don't we eat horsemeat? | It's apparently more common in Belgium and France. It was considered unclean by Jewish standards, but so was the pig. In the 700s the pope tried to stop the practice of eating horse meat as it was common in pagan rituals. This catholic restriction has persisted in a lot of places and is likely the cause of most objecti... |
If I must wear protective clothing while being exposed to radiation why don't I need to cover my eyes? | The most troubling side effect of irradiation is damage to the genetic material. This is a problem in tissues in which the cells divide and multiply a lot - inside of the intestines, salivary glands, skin. With each division the damage multiplies also and therefore these tissues are considered radiation sensitive. Of c... |
How exactly do animals get domesticated to the point where they're able to be pets and be okay with humans constantly petting and holding them? | Some wild animals are better suited to domestication than others. In general, social animals are easier to domesticate than solitary ones. Cats are less social than dogs, for example, so they tolerate people but aren't as domesticated as dogs are. Among wild or semi-domesticated animals with domestication potential, th... |
Why "In God We Trust" is the official motto of The United States | Fun fact for you, In God We Trust was never on US currency until introduced on the two cents piece in 1864. One of the main reasons was to say that God was on the side of the north during the civil war. Now people take that to mean all sorts of balogna but that's how it started", 'SCOTUS has made exceptions for traditi... |
If I buy stock in a company that goes under or is sold, is that stock still honored? | If it is sold, yes - you now own stock in the purchasing company, or will get cash from them. If it goes under, probably not. You're among the last people in line to get a slice of the pie. |
What happens to Sherpas at sea level? | They actually outperform most other people. Their bodies are used to low oxygen environments, so when they're brought to sea-level their heart works more efficiently than most people and their breathing is much more efficient. [Here's a study] that brought six elite Sherpa climbers to sea-level and subjected them physi... |
Why isn't Obamacare put on a separate bill from the spending plan and voted on separately? | In essence, because the Tea Party Republicans are using it as a leverage point to hold the entire budget hostage. They've flat out declared they will not accept any budget that does not specifically de-fund it. Economic terrorism, in short.The debt limit is explained very well in this video: _URL_0_ The President conti... |
Why do pictures of screens have that striated star-like pattern? | Moirè patterns also show up when photographing stripped or chequed materials with a digital camera. Just _when_ the moirè will appear depends upon the spacing of the stripes, the resolution of the sensor, and the focal length of the lens. We usually just ask actors not to show up in stripes. It's possible to de-moirè a... |
Why is wikipedia a reputable source on Reddit, but not in "real" life (college, etc.)? | Wikipedia is not a unreliable source because of the information and the fact that anybody can edit. Often Wikipedia has very accurate information on a topic. The reason it's unreliable and not suitable for a college/scholastic setting is the fact that it is anonymous. For a source to be academic, you have to be able to... |
If gun restriction laws dont keep criminals from getting guns, how come there's so few mass shootings in European countries? (That typically have strict gun laws) | UK perspective: 1) Criminals don't carry guns generally because it doesn't make sense. No one is going to shoot them for robbery, so why carry a gun which will cause armed police to respond, a man hunt, and extended stay in prison if caught? 2) Many mass shootings aren't by criminals. Having a gun readily available mea... |
If the 18-25 age range is the lowest population group in the US, then why is it the largest target demigraphic for tv and movies? | Older people have their minds made up about many things already, 18 -25 year olds are only just begining to figure out their brand loyalies. If you advertise to the younger generation then not only may you be more likely to get them to try your product but you'll have that new customer for a longer period of time since... |
Why is it difficult to produce fake checks with some of the security features such as gradually fading ink and watermarks? | A common way to falsify checks is to photocopy them. When photocopied watermarks and fading inks stand out in an obvious way so that any bank employee can see that it's fake. It takes an expensive printer to make high security checks so that eliminates most idiots. |
Why does tea need to be hot to be brewed? | If you brew tea using the wrong temperature, it gets bitter. With real tea, different temperatures are required to bring out the correct flavour. It gets complicated - different teas also need different brewing times, otherwise they just get bitter. Most green teas need to steep at 80C/175F for 3-4 minutes . Oolongs wa... |
What are the effects of consuming MDMA, short term and long term? Both physical and psychological | From the experience of several people who have used mdma and who I spoke about this, there are three notable short term issues to be aware of.The first being dehydration. You will sweat a lot, especially since you get a lot more energy and hence you become very active. Simply drinking enough water solves this, but this... |
What happens to an enemy state's embassy in case of war? | Generally you suspend diplomatic relations with your enemies prior to actually declaring war on them. It's usually a sign of bad relations The hope is that the enemy state recognizes the rights of your diplomats, and you can get your ambassador and the ambassador's staff home. Doesn't always happen, sometimes they get ... |
Why do some people have better singing voices than others? | If you strike a 10 inch pan and then a 12 inch pan from your kitchen, they'll make different sounds. That's because different sizes, shapes, and densities of materials make an instrument resonate in different ways. Since everyone's bodies are built differently, we all have different sounding voices. Your unique combina... |
What is actually happening when I feel my stomach "drop" on quick bump on a roller coaster? | I present: [The Euthanasia Coaster!]I believe it was featured on Reddit not too long ago. But I want my own comment karma, god damn it, so I'm linking to the source and cutting out the middle man for you! |
What does it mean when people say Canada has lower gravity in some places than other parts of the world? | I don't know if gravity is lower in Canada than elsewhere, but I do know that the force of gravity is not exactly the same everywhere in the surface of the planet, for a variety of reasons: 1. The Earth is not a perfect sphere; it bulges a bit around the Equator. People on the Equator at sea level are farther from the ... |
Does abstaining from taking medications increase the bodies ability to self heal? | In most cases, no, but you need to be more specific about which medications you're thinking of. Certainly some like aggressive chemotherapy can inhibit your ability to heal wounds. That said, *most* medications work on some version of giving your body a *chance* to heal antibiotics do this for example. They'd be useles... |
Why do humans die because of wrong blood transfusion? | Red blood cells have many different proteins on their surface, with some of these being the proteins that relate to blood group . If a red blood cell has protein A on the surface, there are antibodies to protein B in the blood. So if a transfusion of B blood is given, the antibodies bind to the B RBCs leading to clotti... |
Why do we try to keep people in vegetative states alive, who are not going to recover? | Honestly, I think it's because we don't deal with death well. I've worked in healthcare for about 8 years and have seen a lot of very dead but still living people that are only still alive because their family won't let them go. |
Do green screens have to be green? Also how do they work? | Any color would work. The reason for green is because the human body has little green in it. Same reason why blue is used as well. If you used red, brown, yellow, or anything else like that then undertones, overtones, or other parts of the skin would start to blend in. Blonde hair would blend into yellow or brown. All ... |
How can a schizophrenic see and hear things that aren't there? What is the human mind going through at those moments? | I am not schizo, but I once had a 30 minute auditory hallucination. I have no idea why. I heard an orchestra playing a rich, complex melody with a flute solo . It was about the same volume that a person would speak. I knew it wasn't real because my kids couldn't hear it and I was home with just the 2 of them and it was... |
Why are celebrities practically exempt from the anti-1% statements? | This post is not asking for a layman-friendly explanation to something complicated or technical, so it doesn't belong here. Entirely subjective questions generally belong in /r/askreddit, or you can ask whoever it is that's making that 1% statement. |
Why do so many languages have similar words for parents (mom and dad)? | Because babies mouths produce those sounds first. The consonant-vowel babble is the first intentional sound a child will make, no matter what it's native language or culture. So parents have directed those sounds to mean mother and father in whatever variation their culture and language dictates. Any combination of con... |
Why/ how is Japan a very conservative country, but kind of weird also? | By 'conservative' I assume you are refering to the Japanese culture of hard work and long hours living in a society of very rigid and strict social norms. Think about it, for the majority of your day, and indeed the majority of your life in Japan you are expected to be a sort of corporate robot. They need some release,... |
Why dont we put warm food into the fridge? | The heat from your hot food will warm up the rest of the fridge. This happens any time you add food the fridge, but we like to minimize it whenever possible for a few reasons. 1. Refrigerators remove heat to cool food to whatever temperature they're set. So if you add something with a lot of heat, it has to work a lot ... |
Why do we like the taste of cola so much? | Because of Sugar. Our bodies have evolved to be VERY attracted to sugar, because it is very high in calories and when you're wandering the forests or plains trying to keep from dying, eating some condensed calories is a great way to stay alive. Cola and other sweet drinks/foods just take advantage of our desire for cal... |
Hypothetically, could a download make the PS4 backwards compatible? | From a technical perspective? Sure, you could write an emulator and push it out with a PS4 update. It probably wouldn't be fast enough to be usable, but you could write one. From a business perspective? Never. Going. To. Happen. Developing emulators takes a lot of time . If Sony didn't put one on the PS4 at launch, the... |
Why are chiropractors not considered real doctors? | Well, for starters, they don't even require a bachelor's degree, nor do they even attend medical school. |
if the center of every galaxy is a supermassive black hole then why is it every picture of every galaxy has a bright center? | Because black holes are tiny. A black hole with the mass of ten Suns is only 30 kilometers across. A supermassive black hole might be the size of a star or a solar system, but that's still an extremely small dark object when compared to the entire galaxy. It might block the light of a few stars directly behind it, but ... |
Why is Pro wrestling being fake such a criticism of it? | While the outcomes of pro wrestling matches are predetermined, and the storylines are just that - storylines - it must be borne in mind that the matches themselves are mostly freeform. It's up to the competitors to put on an engaging performance, with the help of the referee, who subtly reads the mood of the crowd to h... |
What's a virtual machine? Why would an org run an application on one? How do they differ in cost/performance from a real computer/server? | Cost.vmware/microsoft has a free hypervisor For enterprise functions you pay, vmware enterprise 4500 usd/ per physical cpu Performance. last benchmark i saw was virtual performance was about 90% of physical.but most of the time the servers doesn't need much performance. simple file/print/domain servers. then it is poss... |
What is the significance of Raspberry Pi? I have a decent technology background, but I'm kind of grey on it? What are some real life applications that you would consider for it? | Technically, Raspberry Pi is no different than any of the other low-cost developer boards that have sold for the last couple of years. The closest similarity might be the [PandaBoard], the [BeagleBoard] or some of the lower-cost SABRE projects like the Boundary [SABRE Lite]. These boards use smartphone-class processor ... |
Why does everyone think people from Canada are nice? | Been to Montreal once and will never go back. Because I couldn't speak French, I was given the royal run around when Greyhound lost our luggage. Quebec seems to be the only province that if you have to change busses, they don't move your luggage for you. Yeah, dicks would be the appropriate word for the majority of Que... |
Why is it that most household cleansers claim to kill 99.9% of Bacteria? | IIRC, it's because the cleaner can kill 100% of bacteria. However, it can't get into every microscopic nook and cranny, so there's a chance of bacteria getting left behind.Assertions on products like this don't have to be accurate. "4/5 doctors choose Colgate" does not have to be fact checked. It can be made up out of ... |
How can guitars have different shapes and sizes, yet all produce the same sounds? | They don't produce the same sound. Hallow-body guitars have a different sound than regular acoustic guitars. There's even a big difference between your standard acoustic guitars. If you don't play guitar a lot, they might all sound the same you you. But if you have played guitar for a long time, they sound very differe... |
If I keep smelling something (like a bag of tea) will it run out of smell? | You have cause and effect reversed. When you smell something, the act of smelling has zero effect on the object. Rather, you are able to smell it because it is releasing volatile molecules into the surrounding air. It will eventually reach a point where no further molecules are released, at which point you will be unab... |
How is gun control not a good idea? | Part of the problem is the demand for gun control generally peaks around periodic mass shootings. It then immediately puts all gun owners on the defensive because the media is declaring that it's the fault of those with guns that this happened. It's also irritating because it takes away all personal accountability of t... |
How does Venmo make money? | I've always heard that while venmo has the money before its cashed out, it's put under an account and venmo keeps the interest generated. It would be fractions of pennies, but considering how much money flows through the app, it adds up. |
Why do the majority of terrorist organisations in the news seem to be Muslim? | First of all, terrorism isn't well defined. There are a lot of organizations which may or may not be terrorists depending on who you ask. The perhaps most obvious example is the CIA, which in parts of the world is considered a state sponsored terrorist organization But if you look at the current news; Terrorism is typi... |
Why are the Dutch and other Western Europeans so much taller than everyone else? | I think one of the main ingredients is a steady, balanced diet over a long time. Of course our genes influence how tall we can become, however without enough nutrition you still won't become very tall. A good example of this is North Korea. Apparently their army has been lowering their height requirements for their arm... |
What exactly is that voice in your head? | Hi! I'm a neuroscientist but, to be entirely honest, this sort of question has remained in the psych realm for quite a while. What you're asking about is the internal dialogue or intrapersonal communication. There's not much research done on how exactly this is done. There are papers that try and locate the source of t... |
Why don't we have memories from infancy and the first few years of life? | I can't be the only one who has memories from like, immediately after birth. Like not *immediately* but I have a distinct memory of being put in my parents car for the first time and going on the drive home. The thing is, the hospital looked just like it did before they tore it down and rebuilt it when I was 7 or 8 and... |
Why do I want to sleep all day when I'm depressed? | Neurologically, depression is linked with a lower amount of serotonin in the brain. Serotonin is a brain messenger for functions like mood. It's also responsible for arousal, otherwise known as awakeness or alertness. Depression generally coincides with lower levels of serotonin, although we don't know what causes this... |
Why supposedly can a piece of paper only be folded in half 12 times? | Folding something in half makes it twice as thick, obviously. So let's say you've got a piece of paper 0.2 millimetres thick.
