how humans are trying to pick up aliens communication? Is it possible that we're missing aliens signals? | Good lord your spelling and grammar are atrocious. I'd almost buy it as just ESL except > some1 Anyway, I was going to just move along but seriously get that under control. Since I need to technically follow the rules and give an explanation to your question or my post will get deleted , it's entirely possible we're mi... |
Does the aftermath of sex between a man/woman smell the same as woman/woman or man/man? | I'd imagine a woman/woman aftermath doesn't smell like jizz, but I'm no expert. When they release porn with a smell-a-tron, THEN I'll be an expert. |
Short selling (stocks) -- explained | Pretty good. I would say you bought the replacement on craigslist that makes the analogy a little closer. I would also add this alternate scenario: PS3 gets discontinued, and the PS4 is delayed, making PS3 sell for $1000. Gary's going to beat you up if you don't return it, so you have go out an buy one on craigslist to... |
How does a free app like emojis come to be a billion dollar company? | Like you're five : you start a lemonade stand. You decide to print 1 billion small papers, called shares, of your lemonade stand company. Your grandma, impressed with your lemonade success, decides to buy 1 share of your company, for 1 dollar. Your lemonade stand is now worth 1 billion dollars. This is how you can get ... |
How and why do we have lucid dreams | There are four main components of lucid dreams: 1. Reflective awareness 2. Cognitive complexity 3. Voluntary action 4. Continuous memory The main difference between lucid and non-lucid dreaming is that in lucid dreaming, you know that you're in a dream and can consciously control what you do. Building off of what U_DON... |
How gas makes cars(Or anything else) work. | Like you're five: Explosions. Explosions, and *Science*. If you mix gasoline with air just right, you get a mist that will *blow up* when a spark hits it. Now, imagine you set off an explosion in an empty soup can with a baseball over the open end. The baseball will get blown off, right? Well, the empty soup can is act... |
ELI 5 - What makes a $50,000 watch worth $50,000? | [this is a 2,400 handbag.] It's made of leather does it hold your stuff better than a $100 handbag? no. Frankly I don't even think it looks that good. But it's expensive, and being expensive is both what makes it expensive and makes it desireable. Sure that $50k watch could contain a lot of workmanship and rare materia... |
Why are salmon from the Pacific prone to parasites while salmon from the Atlantic safe to eat raw? | GF works for a large fish distributor and wants me to tell you guys that parasites, not only in salmon but fish in general, are ubiquitous. It's not about if there are parasites but how big and how many. |
Why and how does a panic attack occur? Is it describable by words? | The flight-flight-freeze response is a normal anxiety response that can go haywire when people are experiencing a lot of stress or don't manage anxiety very well. It's theorized that misinterpretation and intolerance of an anxiety response is what drive panic attacks. Adrenaline kicks off > sensation of anxiety > misin... |
Why does McDonald's receive so much more criticism than, say, Coca Cola or other sweet beverage providers, whose products are just as unhealthy? | I dislike them because of how they gear their marketing towards children. It's almost like brainwashing, and altogether disturbing to see a clown and toys being used to sell junk food disguised as a meal. |
What are the differences between blood types? | you should really use search, because it's really common topic. _URL_0_ here's one, double gilded, very detailed comment about this topic: _URL_1_ |
Can someone explain this quote to me? | I think it means that people who do the right things aren't usually recognised or their good deeds are recognised and that people only remember or see the bad things. |
Why do we want to go to Mars so badly? | Eventually, who knows when, something will wipe out all life on Earth. If humanity is spread out, we've got a better shot at surviving. May as well get a move on. That, and I might actually be able to dunk a basketball on Mars. |
why so many young children's TV shows are created? Why don't they just keep showing the same ones? | I've never done an ELI5 before so this won't be done in appropriate style. I'll give my country of Australia as an example of why this is sometimes the case, though some of the answers re: marketing and new toys/concepts also make sense. In Australia, the government has of course made laws relating to television progra... |
Why does having "good lawyers" get people off with lesser punishments even if they're obviously guilty? | Every profession has different levels of competence. Whether it's a doctor, lawyer or football coach, some are just better at their job than others.I think it comes down to one if those "you get what you pay for" kinda things lawyers get paid buy the billable hour so they will only work for you as long as your check cl... |
How does a metal detector not detect itself? | A metal detector puts out a magnetic field and looks for disturbances in it caused by the presence of other metals. It doesn't detect itself because it is constructed to recognize its own field. |
Why does the sun emit "blue" light while all other fire/flames emit "red" light? | Sunlight is white; it's just the atmosphere playing effects on us, which makes the sun appear yellow. Fire is just oxygen chemically reacting. See, *any* form of energy release produces light, however, most of it is light at frequencies we can't see . Just some, like oxygen, produce light that we can see. The reaction ... |
How does Iran sending two ships to our borders project it's power? | It proves they can provide for their fleet even if it's abroad. You can say it's not useful to cow the Americans or anything, but it does at least demonstrate some capability of their navy. You now know what you probably didn't before because of this move - that Iran has the ability to send warships abroad. |
Why it's normal in our society for kids to not be taught the physical difference between males and females until the beginning of their teenage years. | Rural Midwest USA . most kids know differences between cows and bulls despite misinformation from cartoons . By the time they're old enough for 4H they know heifers from steers. Chickens and roosters are even easier . Turkeys have beards vs hens. Buck = antlers, Doe = no antlers, Doe with antlers = Obama's fault |
How do organs stay in place? | Everything is surrounded by a membrane called the peritoneum. Basically it lines everything and is attached to everything so it isn't able to move around. Your intestines, for example, aren't just one big sloppy pile of spaghetti and wouldn't just come flowing out like they show in movies and stuff. If you've ever done... |
How China can be Communist, yet everyone earns different wages. | China has a market economy . The party that has been in control since 1949 is *named* the Communist Party, but China would not classify as communist in practice. Before the economic reforms beginning 1979, China did used to have a more or less communist economy . Back then there was a lot of collectivization in agricul... |
Why do JPGs look worse every time you compress them? If I round 4.2 to 4, it'll still be 4 no matter how many times I round it. | Continuously recompressing converts the image like this: 'bitmap' - > 'frequency map' - > 'bitmap' - > 'frequency map' - > etc., When going from 'frequency map' to 'bitmap' you will never get _exactly_ the same image back even if you didn't intentionally compress it, because there will always be some small rounding and... |
Why do we go "hmm" or "uuh" when we're thinking? | They're called non-lexical conversation sounds or non-lexical vocables or fillers. See _URL_1_, and _URL_0_", 'Fun fact, different cultures have different things like that. Americans go um, British people go er or erm, and Japanese people go Eto. EDIT: [A source]', "It's cultural. The French often extend the last word ... |
why do so many athletes who were great in college fail at the professional level? | Remember that every time you move up a level, the quality level rises dramatically. Every D1 college player was a superstar in high school. Every pro player was a superstar at a D1 college. When a player is amazing at a lower level, it's at least partly because the competition is weaker on average. Sometimes they reall... |
Why USA is the most popular country for immigrants? | We are the biggest economy in the world, we have a lot of agriculture and service jobs that immigrants can easily do, and we are so ethnically heterogenous that immigrants don't stand out. |
Why does fiber optic internet service often have equal download and upload speeds while cable and dsl have disproportionately higher download speeds? | I think it has to do with bandwidth. The physical limitation of how much data can simultaneously pass through cable/dsl is low, so ISP's use software to reserve only a fraction of the bandwidth for uploads, since people generally download far more data than they upload. Fiber optic has such a greater bandwidth that it ... |
Why does restarting an electronic device often fix whatever problem there was? | Software isn't perfect. And there are many layers of software running in a computer--machine language, operating system, applications, macros, and scripts, to name a few. Software mistakes can cause the data and instructions in the computer's memory chips to become corrupted. Restarting the computer clears out the memo... |
The reason a significant amount of people think vaccines cause autism. | [This article] includes a video from CNN. The first few minutes contain a pretty straightforward summary of what happened. Basically, a study was published in a prestigious journal in which researchers suggested that there may be a link between autism and the MMR vaccine. The article itself didn't do much by itself to ... |
Why is laughing so contagious? | Also due to a thing called Mirror Neurons. When you see a recognizable facial expression , part of your brain cannot differentiate whether YOU are making the face or you are just seeing the face- it just lights up the experience of that expression. That's why it works so well to give a reassuring smile or to act happy ... |
What Happened to Google Search? | DDG is good; I also use [these guys] sometimes. As for your question, it's hard to say, but I think they got a too clever for their own good. Everything is based on popularity, not accuracy. Popularity was always an important part of PageRank, but they've taken it too far, imho. *Edit*: P.S. If you've been on the 'net ... |
Why do people tap their glass on the bar before taking a shot? | It started as more of a competition to who could drink the shot quicker. You're essentially racing by tapping the bar and bringing the shot glass back up for consumption. Anyone who has played flip cup would have seen this when the first two people start drinking. They cheers, hit the table and then begin the race.No o... |
Why is cancer so common, even though we have so many possible mutations that can occur within our DNA? | Some bits of DNA are more likely to mutate . Some people inherit mutations that make cancer more likely. You can pick up a lot of mutations that do nothing, you'll just never notice. Some mutations increase the rate of other mutations occurring.Cancer is not one mutation, it is many. They just have similar effects. /tr... |
When people/companies sell books on Amazon for $.01, plus a reasonable amount of S+H, what's their motivation? | Another thing to consider is a lot of these sellers buy large consignments of books from estate sales and other places. From these thousands of books they make most of their profits from the handful of rare and valuable books. Everything else after that is just getting rid of the leftovers. Ex. I buy 1000 books at an e... |
Why can't they evacuate the Carnival Cruise passengers by boat? | finally a question that involves me expertise! First off let's start with what a boat/ship do. They float. They are not like buildings that are on solid ground, they are on water and water can be choppy . Even dropping an anchor does not make a boat completely steady. When two boats go next to each other, the water bet... |
At what point does a game become “solvable”? | If you can play a game then it is clearly solvable, but may not be solvable in finite time. The problem with chess is that there are too many possible games. [Shannon's number] puts a lower bound on the number of possible chess games at at least 10^120; it is literally impossible to calculate all of those since there a... |
Why do I get severe "carsickness" while playing games? | Motion sickness is caused by either feeling motion and not seeing it, or seeing it but not feeling it. In the case of video games, you see motion, but you don't feel it and your brain doesn't know what to do. Your brain concludes that the reason your sight and sense of motion are in conflict because you have become sic... |
Why is Shakespeare such a big deal? | Have you read any Shakespeare? It's pretty damn good, especially considering just how old it is. |
Why do school buses not have seat belts? Can people sue the school district when collisions happen? | /u/manateecalamity is correct. School busses are actually designed such that seatbelts aren't as necessary. There have been *extensive* studies done on the subject, and the NTSB is entirely on board with the no-seat-belt thing. Public transport busses basically work the same way. Now don't get me wrong: the school dist... |
why does helium make your voice so high pitched? | Your voice is a product of air going through your vocal cords. Helium is lighter than 'normal air' meaning it interacts more gently with your vocal cords. This is also why heavier gasses make your voice lower. |
How Do Dental Records Help Identify A Body When It's Too Badly Damaged To Identify Otherwise. | > What are these, and how are they able to identify a body by them? Where are these records kept? The records are kept by dentists. If you suspect a body is a particular person you can go to their dentist and get things like x-rays of their teeth that can identify unique structures, fillings, etc. that will confirm tho... |
Why do people cut their wrists? | As someone who cuts his thighs rather than his wrists, it delivers a similar rush of chemicals to an orgasm, it brings a sense of euphoria and control. Just takes your mind off the shit going on in your head, but it's pretty temporary. |
Why did the Freedom Tower cost $3.9bil but the Burj Khalifa cost $1.5bil? | While I don't know the entire costs. I know that there was criticism of the Burj Khalifa for dangerous working conditions and **terrible** wages for the people doing the actual building work. Workers were paid < 5 pounds a day. It's easy to save a lot of money if you pay workers very little.People are talking about lab... |
How do bail bondsman earn their money. (Like Dog the Bounty Hunter) | In Dog's case, he earns his money by putting roach clips in his hair and posing on tv. |
Someone, please explain the current world economic situation in a nutshell. | Currently, much of the world is looking at a shortage of jobs as economies transition from industrial to more efficient post-industrial economies. Like you're five: it now takes fewer people to make more things, so jobs will be harder to get in many countries. |
What is the difference between weeds and other plants? Do they negatively affect the growth of other plants somehow, or is it a matter of aesthetics? | A weed is any plant growing somewhere you don't won't it to be. It's primarily aesthetics. What we consider weeds are typically fast growing invasive plants. If you are trying to grow grass, which is nice, soft, pretty, and relatively uniform then many fast growing plants become a problem. They may be ugly or hard to w... |
Why is glycerin such a common ingredient in toothpaste even though some studies have apparently shown that it prevents the remineralization of the enamel? | Without it, toothpaste tastes like minty chalk, and you can't exactly sell sugar-filled toothpaste.The true question should be, Why is there sand in toothpaste? It literally grinds away and polishes the enamel of your teeth. You should always avoid using toothpaste that uses hydrated silica/silica of any kind. My wife ... |
How could we land a rocket on the Moon in 1969 but now struggle with landing one on Earth (just recently achieved by SpaceX)? | 1. The moon's gravity is 1/6th that of earth. 2. The moon has no atmosphere. Thus the moon lander faced no risk of burning up on reentry, and didn't need to worry about aerodynamics. Edit: Also, 1960s engineers didn't have Reddit, so they actually got work done. |
Why do I feel like I can swim faster at the bottom of a pool than when I'm at the top of the pool? | I doubt you're actually swimming faster. You're closer to the bottom of the pool and you perceive the floor moving past you faster than you do when you're at the top. Driving 80 mph inside a tunnel may feel faster than driving 80 mph along a flat open desert highway for the same reason. |
why are LED's such a big deal? Scientists nominated for the Nobel prIze due to their work on LED's has me thinking there is more to them than I thought. | LED's are much more energy efficient than incandescent bulbs, and also last much longer and run cooler. They do not have the mercury content of compact fluorescent bulbs, either. This makes them desirable for lighting. In order to be used for general lighting applications, you need white light. Blue LED's, required to ... |
Why when I get my computer Password correct it logs me in almost instantly, but if its wrong takes more than a few seconds to reset itself | Password guessing slowdown as mentioned by others Also on very large networks the Active directory may be controlled by the Admin IT staff on a dedicated server and any password update/change is generally done on this master AD server. However your login request may be handled by a more local server the password update... |
Why is mp3's still ripped in 128kbp/s and not simply in either 320kbp/s or straight flac? | It's important to note that the sound quality difference between a lossless audio file and a 128Kb/s is so minute that less than 1% of people can really tell. To prove my point, take [this test] FLAC is also not a well supported format . It's also a very hyped format that people seem to think improves the quality Third... |
Explain like I'm 5: Metagaming and metagaming analysis in video games. | 'Metagame' refers to the stuff outside the game. For instance, lets take the game 'Rock, paper, scissors'. On the surface, this game is very simple: rock beats scissors, scissors beats paper, paper beats rock. Just from the game rules alone, it seems like the game should be nothing more than simple chance. Now, lets ta... |
Why do strangers on tv have their faces blurred when it's completely legal to take pictures of famous people and post it everywhere without their permission? | If you take a picture of a celebrity at a film opening etc. Then by their actions they are accepting that they will be photographed and the pictures made public. If you lean over their wall and take pictures of them in their garden then they haven't. Strangers as you call them have a general right to privacy as they ar... |
Why do stores carry pre-paid cards. | Lets say you buy a $10 McDonalds gift card from Target, Target did not buy that for 10, lets just say for easy numbers they spent $9 on it. So Target now made a quick buck. So why does it make sense for McDonalds to sell target a $10 card for $9? Because generally people won't ever pay exactly the worth of the giftcard... |
Why is the name of the letter "W" so different from all the other letters? | Because the letter originated from the lack of a letter representing the sound. Originally either a v or uu was used, giving it the name 'double u'.Well, the name is pretty self explanatory -- it's called "double-U" because it used to be written as two of the letter "u." It didn't get its own name because it wasn't con... |
If we can tell someone's blood sugar levels from a finger prick test why can we not do the same for THC levels? | You can measure THC in blood, it's measure in nano grams. Blood sugar testing costs a few cents and the THC test is very expensive. There are methods to measure it from your saliva which are cheaper, but there's discrepancies about the effectiveness of the test. You can detect almost all substance in blood tests, the p... |
Why can some murderers plea insanity? Surely all murderers are on the insanity scale to be able to carryout such an act? | Murder is not inherently an irrational act. Neither is theft, assault, or a litany of other crimes necessarily indicators of any form of mental illness.We all have an internal narrative, and insanity is when our internal narrative is in obvious contradiction with objective reality. A person's narrative could very close... |
Just how much less nutritious is food that has been frozen such as frozen fruits/meals | caloric nutrient value tends to not change at all with any food if frozen over any time frame.the ash nutrient value tends to not change at all with any food if frozen over any time frame.the vitamin nutrient value may change drastically if frozen over any time but doesn't have to depending on the form and type of vita... |
What happens to the human brain when using a smartphone before bed? | You get distracted and perhaps if using high brightness, you make your body think it's earlier than it really is, delaying your sleep preparation mechanisms until you stop using it . Same thing happens with all electronic devices that have a bright screen. Flux is a software that helps with this. As for if it's that ba... |
Why do the 3D glasses I get at the cinema not work on my PC at home with youtube or any other site? | The 3D glasses you got at the cinema work by blocking circularly-polarized light. One lens blocks clockwise-polarized light, and the other blocks counterclockwise-polarized light. The projector projects the image for one eye polarized in the direction that it *doesn't* block, and projects a different image polarized in... |
Why has mass murder been a part of many different communist regimes? | Why? It's a difficult question to answer, and one that could equally be applied to capitalist regimes or indeed any regime, including those that existed before such divisions were even conceptualised. Mass murder is just a part of the human condition I suppose, we aren't as moralistic or ethical as we like to think. Wh... |
Why do I have weird dreams when I am sick? | Fever and discomfort alter you sleeping patterns. You may have the same dreams normally, but when you're sick you happen to wake up in a different stage of sleep so you remember the dreams. Also, external stimulus can alter dreams, so maybe the physical discomfort makes you dreams take on a different story.Do you take ... |
Why are electric cars so highly favored if lithium is not a renewable resource? | I would imagine that in 300-400 years our battery technology will have progressed beyond the need for lithium, I wouldn't worry about that too much . In the meantime the greatest benefit is that electric cars themselves produce no greenhouse gases. The electricity used to power the cars may have come from burning fossi... |
What makes a battery "rechargeable" and why do they get worse the more times they have been recharged? | A battery works through a physical process that produces an electric current. In a rechargeable batterly, it's a process that can be *reversed* by applying an electric current in the opposite direction. But this process is not the only thing the substances in the battery can do. Depending on a variety of factors, a sma... |
what the affect of un-vaccinated children have on the rest of us if we are vaccinated? | Here's a short list: 1. Diseases. 2. A higher chance of death from preventable diseases.3. Stupid parents. |
Why is TI still the only main calculator brand for school? Are there any serious competitors? | I had to buy a graphing calculator for a college course and I went with a Casio. It's still outdated but it's not quite as expensive. |
How would an official anarchist country work? | Actual anarchy would lead to chaos. The entire point of having a government is to peacefully resolve disputes amongst a citizenry. Lacking that government, the only way to resolve disputes is on an individual-to-individual basis - and since 'gun' trumps 'reason' in such debates, you'll find the people winning the debat... |
How do humans survive the high UV indexes of cities which have high elevations and are in the tropics? Cities such as La Paz and Quito and Bogotá have high UV indexes. | I don't know man. But, whenever I'm in La Paz, I'm always more bothered by how damn high, and how damn cold it is. |
Why is pi (π) considered to be irrational even if it can be represented as circumference divided by diameter (c/d) | Yes, but can c/d be represented as a ratio of **integers**? That's what defines a rational number. Just because a number can be written as a ratio doesn't mean it's rational. You have to be able to write it as a ratio of integers. |
why do human babies cry but most animals' young do not? | Loads of baby animals make noises to alert their parents to something that might be wrong. Just think of hatchlings chirping in a nest) or to beg for food. Human babies also have the advantage that they are never left alone so being silent isn't an advantage for them. This unlike, say, baby deer, who are left alone whi... |
Why a stronger relationship between America and Russia would be a bad thing | It's not a bad thing in general. The issue at hand is how Russia has been acting on a geopolitical stage, less than 3 years ago it invaded and annexed Crimea, as well as it has been propping up the seperatist movement in the east of the same country. The issue with pushing for thaw relations right now is that it would ... |
How are the Oscars seen in "over 200 countries world-wide" when there are only 196 countries in the world? | Because no one can agree on what is and isn't a country. Is Palestine a country? Is ROC/Taiwan? What about Northern Ireland? Depends on whom you ask. |
Does a suicidal person who has definitively decided to die still fear things that might normally feel scary/threatening (like heights, driving recklessly, walking alone at night in a high-crime area, etc)? | Yes. Often depression is partnered with anxiety. I've been on the verge of suicide before and terrified of being out at night. Ask, a big reason why I never fully attempted to kill myself was due to my fear that it was going to hurt. |
Could there be any benevolent reason why the involved governments are being so secretive about the Trans Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership? | Because *all* trade negotiations are made in secret, and then the results published. It's really the only way it can work -- they go into a room, close the door, and come out with one voice about what they want. This way you don't know who was where, what positions were taken and dropped. This is vitally important beca... |
The thought process behind the numbering of US military units. | Mostly because today it IS semi random. Being as much a jockeying match about which unit traditions and legacies got stood down and cased up and which survived. The units we have today are essentially the end result of a 60 year draw down from the peak of 1944-45. Back then you would have had 100's of divisions, 1000's... |
What keeps a health insurance company from running their own clinics? | You're describing an [HMO], there's rules about how they're run, but, yes, it is done as you describe. |
Why is a group like ISIS getting a bunch of hate, yet cartels get almost nothing for doing the same thing | Because cartels operate within their own countries or regions, so it's a local or national issue. ISIS are killing members from outside of their country, who pose no real threat other than reporting what's happening, so it's an international problem |
I'm suffering workplace bullying and am making contemporaneous records on a personal Google doc from my work PC when things are said to me. What data/metadata can my employer see about this Google doc? | Your employer can erase it, and that should be enough for you! Are you forbidden from bringing a thumb drive with you to work? You could write the file to that, and only that, and only put the drive in when you're editing. They might be able to see it but they won't be able to delete it without working out some pretty ... |
What is a coulomb? | The reason for the amount is that it's the amount of charge transported by a 1 amp current in 1 second. But really, it's just like moles: -1 coulomb is the charge in 6.241×10^18 electrons . |
The argument against net neutrality. | Not all data necessarily needs to be treated equally. Maybe some people don't need max capacity at 6pm and could pay less, whereas others do and should pay more. Maybe some need reliable capacity, maybe others don't etc. Giving priority to those who pay extra is a principle that's in place in many areas, from delivery ... |
I give up. Exactly how do resistors work? | You need to determine the maximum safe current for the LED. Back when I used to work with these a lot, it was typically 20 mA or so. Then you need to determine the supply voltage. Use Ohm's law to determine the resistor you need to limit to that current. Then calculate the power for the resistor based on the voltage an... |
Would modern warriors stronger because of better nutrition, training and evolution, or are ancient warriors stronger because of harsher living conditions and a greater emphasis on physical capability in the past? | The warriors would be mostly equal but I guess the advantage goes to the modern warrior because he'll more than likely be taller and have 40lbs on the past man. |
Why do black people in the US believe that Cleopatra and Ancient Egyptians were black? | Cleopatra in particular was Greek, but for the earlier Pharaohs we're not really sure. The Egyptians didn't seem to be particularly concerned with the distinction, and a few of the Pharaohs were from Nubia so they certainly were. Given that the modern population has been greatly influenced by migration from the Middle ... |
Why do warm drinks not seem to quench your thirst or hydrate you as well as a cold drink? | Either will hydrate you just the same as they have the same amount of fluid. A cold drink, though, cools your body from the inside which is more effective than external cooling. When I'm overheated and get an icy canned beverage, instead of drinking it right away, I put it up against my neck or wrists where major blood... |
Why are people against the California High Speed Rail? | It's really expensive and its probably going to cost more money than projected, and take longer to build than they say. It's also not that fast compared to Europe/Asia |
Why H2O is vital to life, but H2O2 is dangerous | The extra O falls off, and immediately rapes the hydrogen off the first molecule it can find. If that's one of your molecules, we have a problem. |
Why does poking my amp cable against my guitar and myself (and presumably other stuff) play a radio station through my amp? | Others are on the right trail, but leaving out an important aspect. In order to hear an AM signal on your amp, it needs to be demodulated. AM demodulation only requires a rectifier , and the circuit in your amp has a diode built into it. Both tubes and transistors can function as diodes. Two dissimilar metals can also ... |
Is it possible that cancer - of all kinds - will ever be completely cured? | Completely? Doubtful. Cancer isn't something you really catch. Each case is a little bit different. It's a mutation in your own cells, so it's kind of like depression in a way Everybody's body reacts differently to treatments, so it's really doubtful that there's ever going to be something that fixes every case. |
What are these star like miniature white moving dots you see when looking at the sky? | If they're really faint white dots and they're following the same paths, they're white blood cells. When red blood cells block light coming in to your eye, it turns out that your eye is very adept at ignoring that. However, white blood cells don't absorb blue light well, and so when your eye focuses on a blue backgroun... |
Why do some people argue that taxes is theft ? | These people are probably saying that freedom is a fundamental right, and only those agreements and deals you enter into voluntarily can respect that freedom. Taxes aren't voluntary, they are imposed on you by the will of the government, whether you want to pay or not. Ultimately, the government relies on the use of vi... |
why is the amount of caffeine not listed on most food products? | To clarify some other answers here 1) It's not required by the government. You don't have to list a chemical components of an ingredient if it's a common ingredient . 2) Those companies that add caffeine in chemical form do have to list it clearly - Monster has 100 mg caffeine / serving . 3) There is a law about the ma... |
