[ "The same that happens when you change gears in your bike, my dear 5 year old. You want to pedal a lot and not be tired or pedal a little and with all your strength, climb that hill. That's manual transmission. Automatic transmission makes the choice for you. The motor of the car is coupled to the wheels in such a way that it transmits the rotation of the motor to the rotation of the wheels. The rate at which this happens is the gear. Reverse adds a further cogwheel to the system so that the rotation of the motor gets transmitted backwards to the wheels. Manual transmission requires you to disengage the gear before engaging the next. That's what you do with the clutch. You \"disconnect\" the motor turning cogwheel from the wheel's turning cogwheel. Select appropriate cogwheel (gear) release the clutch so cogwheels are \"connected\" again and motor rotation is transmitted Automatic transmission forces the gears to slip to the next one whenever the motor reaches a certain number of rpm. In manual transmission you have full control of the motor. Look at this [diagram]( URL_0 ). The cogwheel from the engine is green." ]

With that the network \"trys\" to avoid to use the exact same frequency as a near by network and to avoid on this way to \"collide\" with each other. There won't be a total signal loss if two networks send on the same frequency, but the packet loss and therefor the speed and reliability will suffer." ]

[ "You can design a very primitive Akinator of your own by just drawing a big tree-shaped flow chart on a piece of paper. First things first, come up with a question, any question. Let's say question #1 is \"is your character an adult?\" Write that down in the top flowchart bubble, then draw two lines coming down from there, one for \"yes\" and the other for \"no\". The first few times you play this game with someone, it will be very short and unimpressive. You'll say \"Is it an adult?\" And they say \"no\" and you say \"huh, I'm stumped. Who is it?\" And they'll say \"Dora the Explorer\", and then you write down \"Dora\" on your chart under the no. Then you play again with someone else. You ask \"adult?\" and they say \"yes\", and you see that you have no one written down on the \"yes\" branch of the tree. So you say \"I give up, who is it?\" And they say \"Superman\". So you write down Superman under the 'yes' branch. Now the next game is a bit more interesting, but still not so impressive. You ask \"Adult?\" and they say \"No.\" and then you follow the \"no\" line on your flowchart and find you've got a name there! So you say \"I know! It's Dora the explorer!\" and they say \"Nope, it's Timmy Turner.\" So you write down Timmy's name next to Dora's. Now, you have 2 names at the same node in your tree. That's a problem. So now you have to extend your tree. Ask the player: \"What's a question you could ask, where the answer would be yes for Timmy but no for Dora?\" Maybe then they say \"Is the character male?\" Write that down on that node of the tree, and put Dora and Timmy below it. So now, your updated tree looks like this: [ URL_0 ]( URL_0 ) If you keep doing this thousands and thousands of times, your flowchart will get bigger and bigger untill you start actually getting quite a lot of guesses right. You are basically letting your players do the work of teaching you what characters exist, and what questions you can ask to determine who they are. & #x200B; Now this is a pretty cut-down algorithm. The real Akinator has a little more complicated logic in it to account for the fact that not everyone answers the questions the same way, even when they're thinking of the same character." ]

[ "The port is nothing more than a specified way to transfer signals. I'm not familiar with lightning ports specifically but I'd assume it has a way to transfer power, and a way to transfer data. Every device that uses a lightning cable follows the same standards that the port has so it knows it gets power and data over specific parts of the cable. So when you plug a device in, every device works effectively the same way. It transfers data over the cable and the computer/phone/whatever that has the port is able to use the data it transfers to identify the device. Once it knows you have (for example) an audio device connected, it knows if it transfers audio signals to the device, the device is capable of using them properly." ]

Pets with aggressive cancer often only will live months to 1-2 years (with a few exceptions, notably low grade B-cell lymphoma that respond well to treatment), so the expectation is not usually a cure/remission, but to provide as long quality of life as possible, which would not be the case if we hammered them like they do in people. However, pets still do get side effects of chemo drugs affecting their rapidly dividing cells, but is usually limited to temporary bone marrow suppression and GI signs (vomiting, diarrhea). People with cancer can live a long time if they reach remission, so they tend to be more aggressive, plus people understand the pro/con of the suffering and sickness of going through chemotherapy, making it worth it.

[ "Glucose is our staple energy source. If the body needs energy, glucose is broken down producing ATP and releasing CO2 and H20. If the body does not need energy, the glucose is built in to chains for easy storage in liver. These chain molecules are called glycogen. They are easily accessed and broken down to glucose whenever blood sugar levels decrease to provide the body with energy, During starvation, when there is no energy provided by food, the body has to break down it's 3 main energy stores - liver glycogen, body fat and muscle. Your body begins by breaking down the liver glycogen. Next is body fat and and if desperate - muscles. In terms of weight and total calorific content this comes to, for an exemplar 70kg male; about 0.2kg liver glycogen = ~800kcal, about 15kg triacylglycarides (TAGs = major component of body fat)= ~135,000kcal and 6kg muscle = ~24,000kcal. As you can see, body fat is the major energy store of the body. Fat cells exist partly to be used as an energy store. However, the body will break down glycogen first always as its simpler and more direct. Breaking down body fat (TAGs) for use as energy requires two more complex processes; 1) beta-oxidation of fatty acids to the natural precursor for a specific stage in the same natural metabolic pathway as glucose, and 2) gluconeogenesis, producing glucose from glycerol ( a non-carb source!). Muscles are the last to be broken down, for obvious reasons - we need them. Muscle breakdown doesn't only affect things like leg and arm muscles, but also things like cardiac and diaphragm muscle, so it is really a last attempt for the body to survive by breaking these down. This would probably be around a couple weeks in to starvation and death would soon follow." ]

It can tell you all kinds of stuff: Hot/cold, rough/smooth/sharp/dull, vibrations, pressure, pain, and even where it is in space. (A good neurologic exam can look at all these separately.) They're often a bit different in the way they're sensed and how that information is passed along, which means drugs may hit them differently: \"Local anesthetics have greater affinity for receptors within sodium channels during their activated and inactivated states than when they are in their resting states.1,2 Therefore, neural fibers having more rapid firing rates are most susceptible to local anesthetic action. Also, smaller fibers are generally more susceptible, because a given volume of local anesthetic solution can more readily block the requisite number of sodium channels for impulse transmission to be entirely interrupted. For these reasons the tiny, rapid-firing autonomic fibers are most sensitive, followed by sensory fibers and finally somatic motor fibers... The dentist is generally spared this consideration because the trigeminal nerve branches anesthetized for dental procedures are comprised only of small, rapid-firing sensory fibers. However, the many classes of sensory fibers also vary in their diameters and firing rates. For example, pain fibers are more sensitive than those carrying pressure and proprioception. A patient may remain disturbed by a sense of pressure despite complete anesthesia of pain fibers.\" ( URL_0 ) **ELI5: To shut someone up by throwing a sock in their mouth, their mouth has to be open.

[ "Two hundred years or so ago, James Clark Maxwell was coming up with a bunch of equations to describe how electricity and magnetism are related. During this, he came to a rather bizarre conclusion. He realized that magnetic and electric fields could actually self-perpetuate; they could sustain themselves without a nearby magnet or electric device. They could propagate as a wave, with no need for nearby wires or magnets. He also concluded that, in air, these waves would travel at 299,700,000 meters per second. This is electromagnetic radiation - an alternating magnetic and electric field traveling independently of a wire or magnet. Being a wave, this electromagnetic radiation can have frequency. When experiments showed that visible light also travels at this speed of maxwell's waves, it began to seem as if light was also this electromagnetic radiation, but at a much higher frequency (more waves per second). This is indeed the case." ]

Every thing people in a country buy or service people pay for. This measures roughly the economic output generated by that country over the course of time. It's one of many measurements used to reflect what is going on in an economy. More useful is GDP per capita, which is simply the GDP divided by the number if people living in the country. So a country with a high GDP but also a high population such as China would have a lower GDP/cap than the United States which has a higher GDP and a lower population." ]

In physic, both for newtonian and quantum, there are energy levels. This levels are also called as potential. Every particle in the univers want to be the lowest possible energy level/potential. This is called stability. For example; visible light is simply an excess energy comes from an electron moving from high potential to low potential. Remember this information. Imagina a circuit. It is just a battery connected to it's own poles with a conductor, lets say a wire. When you connect batteries minus polar and plus polar, you create a potential difference. This potential difference causes electrons to move, as expected, tolowest point. When an electron moves, lets assume clockwise direction, it creates an imaginary particle which is called \"hole\". This particles, holes, sre what we call as electricity. So you can say that, when an electron is moving it creates electric on the opposite direction. Hope this will help you." ]

Turning them off and on restores the defaults. Resetting the connection is a bit more complex. The ISP maintains some amount of state for your modem - it knows the modem's IP address (which is assigned dynamically when you connect), and each side has some information remembering agreed-upon details for the connection. Sometimes, one side or both screw up the connection state, and in this case the connection must be torn down. The longer gap is to make sure this reliably happens on your ISP's side, instead of the ISP's side just deciding that the connection is slow for a bit.

[ "The premise of your question is flawed. Prehistoric animals weren't bigger than our modern animals. The largest animal to ever exist is the blue whale, which only evolved reletively recently. Many of the large land mammals comparable in size to dinosaurs only died out very very recently (in the last 100,000 years or so). This has an assignable cause that has nothing to do with atmospheric oxygen. It was us. The onset of humans caused mass extinction of large mammals wherever we went. As for the dinosaurs, remember that larrge animals are easier to find in archeological digs than small ones, so we discover disproportionately higher numbers of them than small animals, leading to the incorrect assumption that there were a lot for of them. Also keep in mind that the scale of prehistoric time is very very long. A lot of those animals you think of that existed \"back then\" like in the age of the dinosaurs, did not exist at the same time period as each other. There were few mega fauna roaming the world at any one time, not many. However, insect size is highly dependant on atmospheric oxygen, since they don't breathe with lungs or gills. They absorb oxygen directly from the air into their blood. Therefore, the size they can reach while still being able to get enough oxygen to function is highly dependent on the concentration of oxygen. This means that insects were larger due to higher levels of oxygen." ]

When we awaken in the morning, we have the memory of going to bed the night before, but new memories are rarely made while we sleep.

[ "Basically what happened is that the cost of living, especially rent and home prices, escalated dramatically, but wages did not keep pace. Here's a real-life example: In the old days, when I got married, my ex and I were both making $5 an hour. The minimum wage was abut $2.75 an hour then. Neither of us had degrees of any kind. We were able to get FT jobs out of high school, none of that trying to piece together a living wage from three-PT jobs stuff so many high school grads do now. We could find a 1-bedroom apartment in a decent but not glamorous area for $500 a month. So together, we made $400 a week gross and were only spending 31% of our gross income on rent. This low proportion of rent-to-income allowed us to be able to stay out of credit card debt. We were able to live on a cash basis for a pretty long time. My ex had a skill he used on weekends and by using that skill and selling the work from it, we were able to save up for the down payment on a house. Only needed 3% because of FHA loans. My ex's pay eventually got doubled to $10 an hour and by then we had a child, so we were still living in a $500 a month unit, on the same pay, but now with a baby. My body made the baby's food for the first 6 months, and I even used cloth diapers because disposables were so expensive. We had a washer in the garage and bought a used dryer. I took in ironing to make a few extra dollars, and also made dolls to sell when hand-made dolls were all the rage. I also did some sewing for a friend of the family who was very large and wanted dresses made out of 100% cotton. (Those are hard to find for big ladies, even today.) Eventually my ex got a decent raise and was earning enough to be considered lower middle class. I stayed home with the kids. But the thing that REALLY gave us the leg-up in life was that we weren't paying 50% or more for f-ing rent, and we didn't have to get a credit card to buy food and clothes. We had enough extra cash every month to pay two car payments and buy the needs of life. We did not get into trouble with credit card debt, something I see so many kids in their 20s do now, because we could afford to live on a cash basis. It wasn't easy - especially after we had the first child - but I shopped for used stuff at thrift stores, bought at the Big Box stores, etc. The other thing that was not all that unusual back then was that we could both find jobs that paid almost double minimum wage without any degree at all. We started out adult life at a relatively high wage. There are some trades that still pay that well, but I worked for a family-owned retailer. NO ONE pays retail cashiers or clerks without even an AA degree double minimum wage now - unless it's a legal pot shop in California, I guess. And, if they did, that means in California I'd be paid $22 an hour as a cashier in my county. (Minimum wage is now $10.50 hr. here.) Hell, I'll be a career cashier right now for $22 an hour. This is why, when I talk about the economy, I try to tell people how it was in the old days - the 60s, 70s and early 80s. Then Reagan and the GOP got elected and Robber Baron economic theories took over the country. *NONE* of those GOP theories have been proven to work to lift up the poor, but the theories exist nonetheless. \"Trickle down economics\" - let the rich get richer and it will \"trickle down\" to the poor. **That's a lie.** So, we were lucky to get the jobs we got, but we were also entering young adulthood in pre-Reagan times. We had an economy designed to help us, not hurt us. Today, young adults have an economy mostly designed to HURT THEM. They SHOULD be marching in the streets in rage and running for office. More power to them." ]

[ "Cameras can be hidden in various ways but the most common method is to film at an angle where it is just out of frame. Obviously if the actor was exactly straight on to their reflection then the camera would need to be right behind their head. Another way is to just have no mirror at all and film through a frame that looks like a mirror." ]

[ "The general idea stemed from Ancient Greek concepts of medicine called \"Humorism\". In their model all sickness was caused by imbalances in the four distinct fluids: Black bile, yellow bile, phlegm, and blood. Such ideas make some sort of intuitive sense in that if someone becomes sick they produce an overabundance of phlegm and if someone loses too much blood such as through a wound they will die. Otherwise of course it is complete nonsense, but what people were trying to do with the bleeding is to bring the four into balance. Unfortunately you might identify a fever as a sign of excess blood (blood being associated with hotness due to flushing from exertion, etc) and then decide to bleed someone simply because they have an infection causing fever. Not a great plan!" ]

[ "Your body has 7*10^27 hrdrogen atoms which are spinning on their axes that are all pointing in random directions. When you are placed in a MRI machine, the magnetic field aligns a small majority of those atoms' axes with the direction of the magnetic field. Then, using three big electromagnets called gradients, it slightly alters the rotation speed and phase of these atoms (the gradients pulsing are what creates the loud noises you hear during a scan). It then pulses RF energy causing the atoms aligned with the field to flip 90 degrees so they are perpendicular to the field and are in a high energy state. As the atoms relax and realign with the main magnetic field, they release the energy they gained from the RF pulse. The MRI machine picks up this energy and can pinpoint the locations of the atoms, due to them spinning at different speeds and phases, and reconstructs an image of the tissues in which the hydrogen atoms reside. This is a very basic explanation of the physics involved. For a more in depth explanation, although still fairly basic, check out this awesome youtube video I watched when I first started working with MRI machines.

[ "Yawning opens an air canal that pumps air into your ear from inside. (Sneezing, blowing nose, etc does that also). Changed pressure makes it harder to hear, because ears aren't as sensitive to vibrations due this. Sort of like banging a drum (or any similar surface, really) sounds duller if you press your other palm against it, to block or dampen drum skin from vibrating as much as it normally does. Or for example, try to bang the drum underwater. Ears are all about pressure." ]

[ "I don't know the specifics on Dr. Dre's aneurysm but in general an aneurysm isn't life threatening until it bursts or starts leaking. At that point a lot depends on the severity of the bleed and how quickly the patient gets proper medical treatment. My uncle had a ruptured aneurysm in his brain (this was a couple decades ago) and from what I've been told it was relatively minor. He has zero lingering symptoms after healing from the surgery to repair it. A family friend had one a couple years ago and despite being on the grounds of what is apparently one of the best facilities for this in the western US when it struck (she was a medical sales rep and was just finishing up a sales call). She was effectively dead within minutes of the onset of symptoms (she was on life support for about a week but the prognosis from the get go was that she would almost certainly never recover).." ]

[ "Aquatic turtles DO swallow water when they eat, and actually can't swallow *without* water as they do not produce saliva. But they have a specially evolved esophagus that acts as a sort of pre-stomach. They fill the esophagus with food and water, and then constrict it to expel all the water while keeping the food inside. The food and a small amount of water then enter the stomach. Edit: Three years on reddit and I finally got gilded while I was asleep, and for something turtle related :D. Obligatory \"Thank you kind stranger\", and \"this blew up\".

[ "Multicore can theoretically improve performance. In practice, it does not because scheduling multiple cores is a nearly intractable problem on a general purpose O/S. If you look at the CPU time on your multicore processor, you'll notice almost all the work is being done by a single processor. Multithreading is a much more significant element. What multithreading allows you to do is have multiple threads ready and when one thread stalls, the other can consume CPU time that would otherwise be wasted. Caching is even more significant. The reason those threads get stalled is largely due to 'cache misses'. The memory in your L1 cache is hundreds of times faster to access than your main memory. As a result, any time a program requires a read from main memory, you're left with your CPU idling for hundreds of cycles. Better cache performance and techniques like multithreading (above) and branch prediction can prevent this. Specialized sub-processors also help a great deal. Unlike multiple generic processors, sub-processors solve the scheduling problem by forcing the software to run on certain, specific processors - processors optimized for those sort of problems. Vector processors for graphics are the most common example, but floating point math processors predate them. In the future, you might see even more of these sub-processors to deal with other common, time-consuming tasks. Smaller footprint and more efficient instruction sets can also make processors faster. It may seem like electricity moves pretty fast, but saving a few millimeters here or there makes a huge difference when you're talking about gigahertz speeds. Lower power can also help. A major limitation of modern processors is heat. Lower the power and you lower the heat. Unfortunately, you also increase the interference - which can be addressed by better channel coding (within limits)." ]

Some modems also functions as routers, so you don't need two separate devices. What you want is a wifi extender." ]
