 Why is there an interference with bluetooth headsets whenever shredding documents?

Put electricity of a certain frequency into metal of a certain shape and you get radio waves, like the radio waves that carry bluetooth. Put electricity of a certain frequency into metal wrapped around a core that can spin, and you get a motor, like the motor in your shredder. Since the motor has metal and electricity it will emit some radio waves, if it's designed poorly it will emit lots of random radio waves (essentially noise) at the same frequency as something else like your bluetooth headset. The headset can't "hear" the bluetooth signal over all the radio "noise" generated by the motor in your shredder.

 Do caterpillars lose their head during pupation??

Not sure about the heads - might depend on the species and whether it's an actual head or just the tip of the chrysalis that looks head-like. But what happens inside the chrysalis is almost beyond belief, and a brain isn't involved. Essentially, the caterpillar digests itself - at a certain point in the process, if you were to open the chrysalis, formless (more or less) caterpillar soup would ooze out. Most species retain only a number of groups of specialized cells called "imaginal discs" that contain instructions for growing each butterfly or moth body part. These cells use the caterpillar soup to replicate and form the parts which come together to form the butterfly or moth. Some species also retain parts of their nervous system from the caterpillar stage, but not all do, and the transformation doesn't seem to be controlled by any remnant nervous system. It's hard to say whether a butterfly is the same individual as the caterpillar it came from. I imagine if you could isolate imaginal discs from two caterpillars and switch them without destroying the chrysalis, they's each grow into an adult, but would it be the "soup" that defines the individual or the imaginal discs? What if you only transferred some of the discs? Whatever the answer, it's an amazing process to go from creature to soup to creature.

 Why does a shaken carbonated drink explode?

In ELI5 terms, carbonated drinks have gas under pressure and bubbles. When the drink is shaken the big bubbles that are normally near the top of the bottle can now be found anywhere in the bottle. When the drink is opened, some of the gas escapes and the bubbles reach the opening of the bottle or can, this stirs up more of the gas dissolved in the soda making them want to escape the drink causing a chain reaction and a big burst of foam and liquid. I hope this explanation is clear, if not I can try to rephrase it.

 How do microcontrollers understand/read code?

The different modules in the processor is controlled by control signals. These are single wire signals that can either be on or off as set by the control logic. For example an adder might have control logic to activate it, select between a handful of inputs, set the initial carry bit, activate the output, etc. A register have control signals to set it, clear it and activate its output. A muxer will be used to select input based on the control signal. And so on. So in order to control a processor you need to set these hundreds of control signal to the correct value so the processor does as the instructions say. The simplest way to do this is with a simple lookup table. For each instructions and each sub-instruction cycle you program into the table what exactly the control signals should be. The hardware will then be able to use the current instruction and the sub-instruction counter to look up in a ROM to find out what the control signals should say. The control signals will also read inn the next instruction and reset the sub-instruction counter when the instruction is done executing. Note that this is how they would do it in the 70s. Modern processors are far more complex but the basic principle of setting the control signal to its correct value using some sort of fixed logic is still the way it is done. However modern logic is less fixed and your processor might receive microcode update which change this part of the processor.

 Why do humans, apes, and monkeys have dry noses while lemurs have wet noses?

Wet noses allow for a significantly better sense of smell, but they are larger than dry noses which allow dry-nosed primates to have a separate upper lip. Probably it evolved like that as smell became less important and vision became the prime sense, where an upper lip like that allows for more/better facial expression and socializing.

 Why is the colour blue so rare in nature?

Everything evolves to get better at survival. Birds, bees, and other major pollinators are unable to see blue colour as we see blue. So naturally, those pollinators go towards something that appeals to them. As they cannot see blue as an attractive colour, those plants were not able to spread. Atleast that's how I understand this. There are other theories which are based upon chemical bonds. And that blue pigment is relatively difficult to be synthesized by plants.

 How come peoples head’s get itchy when someone is talking about lice?

Because the brain memorizes concepts, not snapshots like a camera. When you read the word "car", you associate it (remember) the images of quite a few of them, sounds of engines, smells of exhaust, maybe even the vibrations or movements of riding in one, feel of the wind on your face if the windows are down, etc. It's not just visual, ALL of your senses contribute to the concept of "car" that you have memorized. So the concept of "lice" includes that the bugs can bite and cause itchiness, and your brain brings up that memory and you almost feel it.

 What was the Vietnam war about?

During the Cold War, the US had a foreign politics policy of "Containment" - stopping the spread of Communism around the world and stopping the spread of the Soviet Union's influence around the world. This was an example of a proxy war fought between pro-democratic/US-forces and pro-communist/USSR/Chinese forces. Right after the end of World War 2, in 1946, there was the First Indochina War that pitted nationalist Vietnam forces against French forces (as the area was a French colony for a long time prior). At the conclusion of the war, Vietnam was divided into two territories - essentially North (Communist) and South Vietnam (Democratic). Due to various political events that transpired in South Vietnam, the North made a move to reunify the country under one blanket communist government, leading to the rise of violence and ultimately war in the area.

 When humidity is described as, for example, 72%, what is that 72% of?

The saturation point of ~~water~~ air is where the amount of water vapor in the air is at 100%. Now the air can hold more than 100% of the water vapor, but at that temperature the water vapor can spontaneously condense on anything. You see this happen when there is fog on the ground.

 How to live studio audiences work?

The sets are all right next to each other, usually lined up in a row or set up across from each other in a large studio. The most common sets (so for Friends it would be Central Perk, Monica's apartment, and Joey's apartment) will usually be right next to each other to make things easy on the cast and crew. Temporary sets (a girlfriend's apartment, a character's work, etc) are usually built wherever there's room in the studio. They'll typically film the entire episode more-or-less in chronological order, doing additional takes as necessary for each scene. The audience seats are lined up facing the sets. Depending on the size of the audience, they'll either get up and move over when the cast and crew moves so that they can sit right in front of the action (smaller audiences) or they'll watch on monitors if the room is too crowded to move everyone, or if the closer seats are also filled. Outside scenes or any extra shots outside of those main sets are usually filmed separately and before everything else. They're played on the monitors for the audience while the cast and crew set up the next scene, so that their laughter can be recorded and so that they can follow the story.

 Apple M1 Neural Engine and what differentiate it from Intel i cores?

There are quite a few differences between the M1 chips and Intel processors. Firstly, the M1s are actually something call a System on Chip (SoC), meaning that it's a single unit that contains lots of different parts. The M1 contains a CPU (the processor), a GPU (a processor specifically for graphics), RAM (the memory the system can access), and the neural engine (another processor that is designed for running artificial intelligence programs). On the other hand, Intel processors only have a CPU (and sometimes a GPU), the other components are separate. Now if we focus on just the CPU there are a lot of other differences. CPUs are given a series of instructions to understand what they need to do. Intel (as well as AMD) use a system of instructions called x86. This is basically a very long list of instructions, meaning that they can do a really complicated operation with a single instruction. This makes them great for a lot of high performance applications. However, having lots of special instructions means that there is a lot of extra hardware inside the chip for understanding and acting on these instructions, this causes them to be less power efficient. The M1 uses an alternate standard called RISC (Reduced Instruction Set Computer). This is a design that has most famously been used by ARM, the company that designs the processors you'll find in the majority of phones. In fact, the M1 chips are actually heavily modified ARM designs. RISC uses a much smaller amount of simpler instructions, and combines them together to perform more complex operations. The advantage is that the chips are more power efficient compared to x86 designs. Traditionally this meant that you'd want an x86 CPU in applications that need high performance, and RISC in ones that needed good battery life. However some other advances we've made in CPU design means that we can actually get really great performance from RISC without sacrificing the power efficiency. x86 is still the most powerful option overall in terms of the raw amount of operations it can do, but for most users this isn't something we need. Companies like Microsoft and Apple have realised this, and so have started to push to use ARM/RISC CPUs rather than x86 for portable devices like laptops.

 why are there a bazillion ingredients/chemicals in shampoo? Is is really that hard to make a simple recipe these days?

Most shampoos are water + oil (ads moisture) + something that makes them mix + something that makes bubbles (surfactant) + pH balancing + fragrances + preservatives + something that makes it feel more bulky (thickener) So once you got all those then you find that the combination of your specific oil + surfactant makes unsightly clumps, so then you need to add a stabilizer. Also some things are uv sensative so you need to balance that. Most modern shampoos are just what used to work + some new amazing ingredient to make your shampoo stand out. So after 10 generations off adding and stabilizing. You get huge lists of ingredients. Also production is easy when you make a standard base, then add ABC for dandruff or DEFG for extra soft or each variation. Source: I manufacture small batch hair products.

This question is wildly broad, since the mechanism of action for various substances can be wildly different.

They're huge conglomerations of various systems. You don't need to affect everything; you just need to affect one special piece of a given system.

 How do authorities track down someone using Wickr or other encryption chats?

Answer: So security and encryption are only as good as the users who use it. In theory, if you never share any other personal details, no, you shouldn't be able to track someone. However, the more you share, the more likely you are to be found through other means. For instance, let's say you always show pictures of your lunch at a certain time, well, then we can narrow down your timezone based on where the time you share is likely around lunchtimes for people. Then you may say you work at a "large software company" and now maybe there are only a couple of those in your timezone. If you share other pictures, you may be able to reverse websearch those pictures and find them on a user's non-encrypted social media platforms (A lot of people will use the same selfies for everything). Even other details in pictures can be used to potentially track you such as landmarks or buildings in the background. If you say you graduated in X year, we can narrow down your age. Most of the time people are sharing way more than they think that they are, and a lot of small things that would never identify you individually, will identify you together.

 Why are the pockets often sewn shut on formal attire?

They're sewn shut so the pockets don't sag or deform or snag on something and thus arrive at you with an issue. Sewing them shut keeps the inside and liner flush with the outside material so you get no bunching or sagging or wrinkles. You're supposed to snip the thread to open them up - is why the threading is so loose, if they didn't intend for you to snip it off they'd sew them tight like those "fake" pockets on some jackets or skirts.

 Will two people searching for each other in a crowd reunite faster than one person searching and the other standing still?

I just wrote a quick simulation of this problem to find an answer! I made the following assumptions: * Two people in a 100' x 100' square room * The simulation ends when one person sees another * Each person has a 45-degree field of direct vision, and a 180-degree field of indirect vision. * People other than our pair are not directly simulated. Instead, each simulation has a "crowd density" variable, **D**, which affects visual ability. * Each person can see up to (100 - D) feet in front of them. * During the course of a second, each person has a (100 - D)% chance of spotting someone in their indirect vision, and a 100% chance of spotting someone in their direct vision (assuming they are within range). * If someone is "searching" then over the course of a second they walk forward 5 feet. They will turn occasionally; the longer they've been going straight, the higher the chance that they will turn. If someone is "standing" then they will simply turn occasionally. * In any given run, a position and a heading is chosen randomly for both people. The simulation is then run twice for those starting positions; one in which person A is searching and person B is standing, and one in which both are searching. * The simulation does 1000 runs for all values of D from 0 to 95. We then look at the average times. My results: For low D-values, **it is usually better for both to search.** In an empty room (D-value of 0), it is obviously better if both people are moving around; it gives us an average 15% improvement if both are searching. Not that it matters too much, because they're finding each other in less than 10 seconds anyway. D-value 25 gives us a 10% improvement if both are searching; D-value 50 gives us a 1% improvement if both are searching (statistically insignificant). Higher than 50, the advantage of both searching disappears. Moving does not increase your chances of being seen because you basically get "lost in the crowd." However, if both are searching then it is not any slower than just one searching! Of course, there is a third scenario - both people standing still. When that is the case, it is very likely that they will never find each other! For this reason, in my simulation **it is always better to search for your friend**. Both people searching is sometimes the fastest, but at worst it is tied for best. **Edited for more science** I added another parameter, walking speed; I tried it with very slow walkers (1 inch per second) and very fast walkers (25 feet per second). People walking fast increase the value of searching (as opposed to standing still)! When they are running around the room, the value of both searching increases dramatically. Two people running in an empty room is *twice as fast* as just one running while one stands still. Two people running in a very crowded room (D-value 80) take 2/3rds the time to find each other as just one person running.

 how do you calculate how much an object gets smaller, the further is is away?

it has to do with a thing called "arc distance" you don't see heights and lengths, you see how much of your cone of vision an object takes up. a 1 meter long object 1 meter away from you will take up ~53 degrees of your vision. another meter stick 1 meter beyond that would take up ~28 degrees of your vision. the math is the geometry of an isosceles triangle, where the non-equal leg is the object being viewed.

 How do plants such as the bee orchid know what the animal they mimic looks like?

Natural selection. Basically one mutation of the antecedents of the plant made the plant look like that animal, that helped the plant being avoided by herbivores, therefore the mutation-gene plant survived, guaranteeing its own reproduction whereas the original didn't survive, therefore not reproducting any longer (this over a looong period of time)

> it's said that we're not really touching anything While you can find this claim often, it is highly misleading and needs a very weird definition of "actually touching".

You are more than just touching an object, you are entering it a tiny bit!

 Why is it that after taking gulps of water to quench thirst, stopping, and then drinking more, does your body hesitate to accept it-- almost as if your mouth is full of water already?

I don't remember the exact name of it, but we have specialized nerves/brain functions that control things like appetite, swallowing reflex, and breath-holding reflex. For example, the "myth" that rabies makes you afraid of water is actually true. Since rabies affects the brain, one of the things it does is make even the sight of water trigger the anti-drowning reflex. Anyways, lots of factors go into how easily you can swallow things - how much stuff is in your stomach, the flavor and texture of what you're trying to swallow, as well as stuff completely unrelated to appetite, such as stress level, body temperature... Basically your body has a crapton of mechanisms from billions of years of evolution. You've simply noticed one of them. & #x200B; Note: if you want to experiment with this, try different beverages. Mineralized water or sports drinks almost always go down easier than pure water because very primitive responses identify that beverage as something safe and desirable to drink.

 why does work appear to go by faster when making an effort to never look at the clock?

It has to do with where your focus is and the fact that your brain doesn't count time like a clock does. It works in memories. If you focus on the clock, you're making memories of time. So when you think back you remember each time you checked the clock and some feeling associated with that knowledge (usually dispair). This makes things seem like they are going slowly because of your frequent checks on the time. But when you think back to the task you were doing, you have no real reference for how long each action was taking you. So you don't get the same sense of time passing when you think back (unless you were timing yourself intentionally). So the time *seems* to whizz by but it's just a trick of memory and perception.

 why do pigeons fly together? How do they communicate which direction to fly in?

They don't necessarily communicate to each other, it's more.of communal voting on where to go. There is some research to suggest the faster birds to lead more often, even if they don't rank high in the pecking order. They tend to stay in the flock because there is safety in numbers. It's easy for a hawk to pick off a solo bird, in a flock it's multiple eyes watching, and in a group the weaker or slower ones are hidden.

Your calculation is definitely right. I'd say they made a mistake there. On the other hand I know people and some are devilish misanthropes. Therefore you should consider that this could either be part of your test or they provided some additional information within the test (or not, in this case they are absolute berserks and you should reconsider your choice of employer). For instance: Grades are considered integers (like 1, 2, 3 and 4). Which would mean there's nothing in between the "grades" 70, 80, 90 and 100. The result in this case would be 80.

 Why and how does full moon affect tides? How is full moon any different to the other stages of the moon?

Because the sun also affects the tides as well. When the moon is full (or new), the Moon, Earth, and Sun are all lined up, meaning the gravitational effect the Sun and Moon have on the tides are combined and at full strength. These are called ~~"neap"~~ "spring" tides. This is contrasted when the Moon, Earth, and Sun form a 90 degree angle (First or third quarter) and the Sun and Moon's gravitational pull work against each other.

 How do internet speed tests actually work? I think I understand ping, but how is bandwidth measured?

Ping is the time it takes to send a message from you to a server somewhere. The time it takes to send a message. Bandwidth is how much data can be transmitted per second. So you can send 1 message in just 1 second to a server. Bandwidth is *how many* messages you can send at once, basically, or *how large* can those messages be is another way of thinking about it. In reality, even large files get broken up into many smaller messages, so really bandwidth is how many messages you can send per second. Ping being how long it takes those messages to get where they are going.

 Why are chemical weapons considered particularly heinous?

Yup which is why nuclear weapons are detonated every week right? /s Chemical weapons generally kill in horrible ways, indiscriminately and with little regard to battle lines or combatants vs. non-combatants. They also tend to kill the environment and in general just ruin things. Simply put... they are so nasty that even humans (which are generally horrible to each other) are like "nah... it's k... we don't need that." Nuclear Weapons (while not officially banned) are de facto banned which is why *nobody has used them since 1945*.

It isn't expanding *into* anything. Imagine an infinitely large rubber sheet, with a grid drawn on it so that the lines are 1" apart. Now, *streeeetch* that rubber sheet so that every line on the grid is now 2" apart instead - that's the expansion of the universe. Notice how it didn't expand *into* anything? The sheet is still infinite in all directions, it's just that now the grid spaces are further apart.

 why don’t we have replacement cartilage?

Cartilage exists as a cushion between bones which means it needs to be soft and firmly attached. Anything we insert into the human body has the possibility to foster infections which means that the inserted substance needs to be non-permeable (i.e. metal pins, rods, hip replacements). We don't have anything that is soft yet non-permeable to act as a replacement SAFELY. And since they also have to be firmly attached we would need a way to glue them on to a living surface without damaging that surface. Much harder than it sounds. Soft things we successfully insert into the human body like fake breasts aren't really attached to anything.

 How do people make so much more money from a stock than the stock even rose, percentage-wise?

The most likely reason is leverage - that is, they used someone else's money to buy (most of) the stock they sold. An example: If I buy 100 share of stock at $10 per share, that costs me $1,000. Then it rises to $15 per share and I sell it for $1,500, netting me $500 profit. That's excellent - 50% - but there's a way to make lots more. I borrow $800 at 10% interest, and with $200 of my own money, I buy the same $1,000 worth of stock and sell it at the same $1,500. I pay back the $800 + $80 interest out of the $1,500 proceeds of my stock sale, leaving me with $620. Subtracting my initial $200 of my own money, I have a profit of $420. Sure, that's less in absolute terms than the $500 above, but I used $200 to make $420, a 210% profit. And if I take the original $1,000 I was willing to invest and borrow another $4,000 at 10%, and do the same thing (buy, sell, etc.), my profit would be $2,100, considerably higher than $500 from the non-leveraged transaction using the same amount of my own funds. The danger is if the stock doesn't go up, I still have to repay what I borrowed plus interest.

 Why does soap perfume/fragrance stick to hands and not wash off like other particles?

The top layer of your skin is a porous, non-watertight material made up of dead, decaying skin. Its only the lower, living layers that form a solid, watertight barrier. This means that if you looked at the top layer of your skin under a microscope it would look somewhat like a sponge. Anything that's a liquid flows into all of the holes that exist in the top layer of your skin and gets absorbed into it. If there is something suspended in that liquid, like the the chemicals in soap that give it its smell then they'll get absorbed into your skin along with the liquid. When the liquid dries out those smell chemicals get left behind. People aren't very sensitive to the smell of most kinds of dirt - if your hands stink its probably because there is a lot of something on it. On the other hand, people are really sensitive to the chemicals they use for imparting good smells into consumer products. This means that when the soap washes away all of the dirt then there isn't enough dirt left absorbed into your skin for you to notice the smell. On the other hand, it doesn't take very much of the soap getting left behind for you to be able to smell it.

 I get the whole conservation of momentum thing, but what about when you just slow down something (like putting the breaks on a car), where does the momentum go?

The Earth. When the car slows down, the tires exert a force on the car to make it slow down. By Newton's third law, the tires push back on the Earth. Of course, the Earth is very massive, so the change in the Earth's spin that results from this force is immeasurably small, but momentum is still conserved.

 How do Unions work?(like company unions)

It's basically the concept of "they can't fire us all" put into organized practice. Big companies are powerful and can (usually) say no to demands that benefit workers but cost the company money, if they're just coming from a single person. It's easier for the company to just fire them and find someone that won't demand so much. Even when lots of workers want the changes to happen, individually they don't have very much power against the company. If they create a union, they can use their power all together by telling the company that they'll all refuse to work if they aren't being treated well enough. Unlike firing one employee here and there, firing all your employees at once (or having them refuse to work all at once) can be a huge threat to a company's profits. This forces the company to treat the union more seriously than they treat individual workers. This is especially true when the workers in question have special skills that make them more difficult to replace (e.g. high levels of education, training in a trade like welding or plumbing, or even just expertise in their job that was built up over a long time on the job).

You use less energy overall. Warm-blooded animals need to burn fuel to maintain a constant body temperature. That means they need to consume more calories more frequently than cold-blooded animals.

 How does Microsoft and Sony compete with similar specs?

They both have a similar release date in mind since you don't want to come out too far after your competition and 3rd party developers want to know when to start making higher end games. As well they have similar price points in mind as you don't want to be way more expensive then the competition. So when you combine the two you end up with similar specs, the best most cost effective hardware that will be available for mass market consumption in year 20XX. There are only two major CPU and GPU manufacturers so both companies are drawing from the same pool unless they completely go out of left field. Sony tried that with teh PS3 and the Cell Processor and got burned.

 Why does parallel parking only work when reversing at the start?

Because your turning wheels are only at the front of your car. As your back wheels get where they need to be while reversing you can turn your front end in. Otherwise you would need to drive onto the curb or much farther ahead to drag your back wheels into the parking space. It’s not that you can’t do it forwards you just need less space while reversing.

 Why are three pin plugs better than two pin plugs in terms of safety, and why?

The ground (the third prong) is a failsafe that appliances and tools can use if they want to. If you have a power tool in your hand and something shorts out inside and electrifies the casing or something else touching you, you would get shocked. But if the tool was designed to use the ground, the casing would be attached to the ground, making the path of least resistance the ground wire and third prong, rather than into your hand. It's like a spillway on a dam or the holes along the rim of a sink or bathtub, there to take away extra water and dump it somewhere other than your floor, just as the ground dumps extra current back into the wall socket, rather than go somewhere current isn't supposed to, like your hand.

 How do cores, i5s/i7s/i9s, different GHz, and 16/32 GB of memory affect a computer performance when working together?

Ok so the cores are part of the cpu. The cpu is, as the name says, the central processing unit. It processes tasks. But to process those tasks, the cpu often needs data to work on. But accessing data from the harddrive is slow. So the data that is needed for processing a task is stored in the memory storage (RAM), because it is build in a way that access is faster. More memory space means that more data can be read fast, which is helpful for large processes like loading a large ampunt of data (like in a gameworld). If you have more questions, please ask.

 How does odor neutralizing spray work?

The sprays use chemical compounds called cyclodextrins whose molecules have a specific shape that allow them to literally trap certain organic molecules like the ones that make up bad smells. That's cool, but for me the really cool part is that bad smells can be made up of a complex mix of different molecules and the sprays only work on some of them, the bad smells still go away because with some of the smell's "puzzle pieces" missing your brain can't really identify what's left, and it no longer registers as "bad". That's why they're called odor neutralizers: all the odor molecules are still there, it's just that some are trapped in a way that they can't get to your smell receptors and the rest don't combine in a way that your brain identifies as unpleasant.

 what is a standard deviation?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range. Large standard deviatoon is an indicator of possible out of control of your process or subject of meadurement.

 Why is disinfecting wounds painful?

There's two main reasons. First, the wound is sensitive, as that part of the body has been damaged and is screaming at your brain to start taking damage control steps. Putting anything in an open wound is going to hurt some. Second, the things we use to disinfect typically do that by killing biological material, which will include the cells around and in your wound. So basically you're quarantining and nuking the area to make sure the infection doesn't spread. The basic part of your brain that handles pain doesn't understand that, or the reasons for disinfection, it just sees more damage to an already damaged part of the body, and registers it as pain.

 how is it that dairy can give people constipation, but then can also cause diarrhea?

The problem with people who can not eat dairy product is that they do not produce the lactase needed to digest the lactose sugar molecules found in milk. So the lactose just goes through the digestion system until it gets to the big intestines. This is where the bacteria is. And some of the bacteria is able to digest lactose and are very good at it. So these bacteria multiply and cause all sorts of issues.

 Why do you humans have to crawl before they can walk? Most animals start walking shortly after birth.

Humans have two big adaptations: Big brains and upright walking that allows the use of tools. But upright walking favors narrow hips while big brains require big skulls, and the skull must pass through the hips at birth! To balance these two things humans are born relatively early and undeveloped, requiring care from their parents (which can be done with our big brains and tool use).

 Why doesn’t there exist a gym which harvests human energy?

Inefficiency is certainly part of it but I think it's also that humans are just weak compared to the equipment we use. For reference, [here]( URL_1 ) is a video of an olympic cyclist trying to generate enough energy to power a toaster. He just barely succeeds, managing to generate a peak of around 700 watts for a couple minutes. But that's definitely not a sustainable rate and the average person would probably be lucky to generate a quarter of that. As another reference point, a gallon of gas contains energy roughly equivalent to [31000 calories]( URL_0 ). The average person consumes about 2000 calories per day. So for a $2.50 gallon of gasoline, you get as much energy as 15 days worth of human energy expenditure. The added complexity and maintenance cost to get pennies worth of electricity per day per machine just isn't worth it, except perhaps for the advertising value. tl;dr there's a reason we don't use human labor to power our stuff anymore, we're pretty useless as far as producing energy goes

 How does autorotation keep a helicopter from crashing in the event of a total engine failure?

There are two effects. One is simple, the other more complex. The simple effect is basically a parachute with more moving pieces. It's similar to a maple seed. As the helicopter falls the air makes the blades spin. It takes energy to make the blades spin, which comes from the helicopter falling. For the more complex effect we look at how a helicopter rotor works. When a helicopter wants to go up it doesn't just increase the speed of the rotor; that would be way too slow. Instead it has the ability to change the pitch of the blades. If you've held a flat hand out the window of a moving car then this should be familiar. Angle your hand up and it makes your hand try to rise. Angle it up more and it tries to rise more. Of course, the more you angle your hand up the more it gets pushed back, too. The blades if the helicopter are doing something similar, just in a circle. When the helicopter wants to land softly it can increase the pitch on the blades. They keep moving in the same direction due to their inertia, but now they're angled up and produce more lift. The helicopter can't do this for long without engine power because this upward angling makes the rotor slow down. Timed correctly it can cushion a hard landing

 Why do packages use TWO arrows to show correct orientation instead of just one?

The human eye is really great at noticing patterns. Your eyes are much more likely to notice a pair of things than a thing by itself, especially in your peripheral. Another benefit of having arrows all over the box is if it’s in the back of a truck, partially covered by boxes in front of it; at least you’d still see one of them.

 Does a 'belief' stop being a belief if it is supported by evidence?

*In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms. -- Stephen Jay Gould* Typically in science, once we pass that factual threshold, we stop talking about belief. It is not necessarily incorrect to say you believe in gravity, but it can be misleading, as it implies it is a matter of opinion. It is kind of like saying "I didn't murder anyone yesterday".
