Why are the larger berries/grapes always sweet, while the smaller ones are always sour? | It's probably due to how ripe the fruit is. The longer a fruit stays attached the plant, the larger it will get. As it gets older/riper, the fruit changes its sugar/acid composition, to more sugar less acid, making it sweeter. The small less ripe ones have less sugar and more acid, making them sour. |
If I build two buildings, right next to each other, how tall would they have to be before the distance at the bottom is different to the top? | Supposing that the building centers are 100 meters away from each other on the ground, then for every 100 meters in height, the buildings will be 15 millimeters farther apart. The empire state building, for example, is 400m tall, approximately, so 2 buildings that tall would be 60 millimeters farther apart at the top t... |
If a planet is in the habitable zone but is ~ twice the size of Earth, why would it be unlikely to sustain life? | TL;DR - By our understanding of life, the planet would have too great of mass to support complex organisms. Just like in real-estate, location is particularly important when it comes to a planet, relative to it's star. Of course, factors of mass are equally, if not more-so important. We humans tend to represent everyth... |
Why are some dangerous mammals, like tigers and wolves, able to be tamed from a young age, but not reptiles like alligators | Because people rarely identify well enough with reptiles to tame them. I was able to tame a snapping turtle that hatched from an egg in my hand - it would try to attack anyone else to the point of trying to chase after them but was always friendly toward me. Body language also has _a lot_ to do with it. Imagine if you ... |
Why did it appear like the media dropped the Ebola crisis from headlines after the election? | You can only hype that everybody is going to die for so long without anyone actually dying.

Hunger is controlled by a much more complex web o... |
Why do Americans circumcise their children? | Not all Americans do. Somewhere between 3 and 4 out of 5 males are circumcised. For many, it's because they're influenced by religious teachings that say circumcision is either a spiritual requirement or preference or they believe it's a healthy, beneficial choice. It does have some health benefits - easier to clean, r... |
Why do all GDPR consent emails have the option to opt in or opt out? | I 've had plenty that only have a "Click here to keep receiving emails" button. Ignoring the emails should be an opt-out, but it doesn't hurt to include an explicit "No thanks" button. It gives you some idea whether people are deliberately opting out or just falling off the list through apathy . Also, some recipients m... |
Why arent movies in 60 fps? | Why would they be? Why not 200 fps? 24 frames per second appears to work well enough to give a sense of continuous motion, and a slower frame rate made it easier to make cameras and made film reels shorter. The limits of human vision determined what an acceptable frame rate was. With 60 fps there can still be problems.... |
Why is it that meteorologists can predict the weather for days in advance fairly accurately, but can't tell if a tornado might be coming till the last few hours? | Let's say you want to travel to Chicago from Atlanta by car. Can you predict your exact position at any given time? No. You can predict where you are going to be in the next few seconds but as you look further ahead you lose accuracy. Sure, you could say, "I'll be near Indy around 6pm on this road, but you don't know h... |
Why is the liver the only organ that can self regenerate? | The short answer is there were enough of our ancestors who survived without having other organs self regenerating that it wasn't enough to drive us to extinction or prevent us from moving to the top of the totem pole.

How do some types of gum produce a "cold" sensation from chewing on them, when the piece of gum itself is room temperature? | It's the same reason the spicy food causes your mouth to feel hot when there is no actual difference in temperature. There is a protein in your nerves called TMAP8 that relays the sense "coldness" to your brain. Chemicals that are found in mints, wintergreen, and menthol and other spices activate your cold sense. Basic... |
When politicians propose limiting abortions to people who were raped or victims of incest, how do they plan to manage that? | Making it near impossible to prove rape or incest in the time it takes to grow a baby is their plan. This way, all pregnancies are carried to term. In most cases, there must be an accused rapist or the woman is deniedI don't see how it's manageable either. I don't think those who have that viewpoint care enough to thin... |
How come we store excess calories as "fat" and what that actually means? Specifically how is protein literally "turned into fat" or is that just an incorrect common misconception? | Proteins are first broken down to amino acids as said, these amino acids are then deaminated in the liver forming alpha-keto acids such as pyruvic acid. There is then a complicated metabolic pathway that leads to them being converted into fatsNot all proteins are the same. Many function in different ways. If you take i... |
Why can't the government create a program similar to the WPA during the Great Depression to provide thousands of jobs while getting long-needed construction projects done? | We totally could! It would just require raising taxes and increasing the size of government . Those are both toxic political ideas right nowSomething else to consider is that the WPA jobs were not in any way meeting the safety standards of today. Numerous workers died participating in the program, it paid almost no mon... |

How come some hot foods will burn our skin if we touch them but I can still eat them at that temperature? | The saliva in your mouth absorbs a fair amount of the heat before the food touches the tissues in your mouth and tongue.When you chew, you're mixing a small portion of food with saliva, which is already at your mouth-temperature, and thus cools hotter food, and air , and you're moving everything around so it doesn't ha... |
Why does my computer get slower over time? | I read your question as "Is it because I accumulate more and more **flies**"Its not the files, but the programs running in the background download a hard drive cleaner like" ATF Cleaner" its free and works great! |
Ginger helps calm my stomach, and meletonin makes me sleepy. Why does it say the FDA hasn't evaluated them or other supplements like Vitamins? | There is a long, and rigorous, process for approval of new drugs. They have to have proven efficacy and safety in a variety of people, populations, ages, sexes, etc. This has to be done in such a way as to eliminate any bias and to show statistically that there is an effect. The substances you're talking about have not... |
Why hasn't the stock market been hacked yet to change the price of particular stocks? | Assuming that is hasn't happened , just like student loans and so many other financial security and national security systems, the computer systems owning the data are disconnected from any common network. In some cases, it requires human action to make any changes. Besides virtual or actual isolation, these systems ha... |
Why does an excess of grease make you feel sick? | Your stomach contains acids and enzymes. Acids aren't very good at dissolving greases, bases are much better at it, but your stomach is acidic, not basic. Eating a lot of grease fills up your stomach with something that it can't easily digest, and as a defense mechanism you'll feel nauseated so you eject it from your s... |
How do adblockers work? | Besides the blacklist method, there's also a heuristic method. For example, if a heuristic blocker sees an ad-sized image in a link, it's probably an ad, so the blocker gets rid of it. Both have weak spots: blacklists won't catch an ad with an unusual URL, and heuristics won't catch an ad with unusual properties; conve... |
Why do dogs have a habit of twitching and pretending to run while they sleep? | When your mommy tucks you in at night and gives you a gentle kiss on the forehead, and you drift into a sweet slumber with your thumb stuck in your mouth, dreams and all sorts of ideas come into your head; some of these dreams and ideas produce involuntarily spasms in your muscles. Now turn your eyes to Grover at your ... |
Why are NFL games broadcasted from the side field camera and not the cable camera directly behind the QB? | Then you wouldn't be able to observe the linemen and the defense. Try watching the game and observing how the line reacts to the play, and that's where the real action is. Good plays and yardage don't just happen, it starts from the linemen blocking, and it's interesting to watch how plays develop just from observing t... |
Why do lamps require you to turn the "knob" twice to turn it on and off? | The lamp you're using is a three setting lamp, but you've put a single setting bulb in it, and it only works on the middle setting. Get a three setting light bulb and it should work properly.Usually a lamp like that is made for a different type of bulb, a 2-stage bulb with 2 different brightnesses. One click turns it o... |

Your bronchial tubes expand to get more oxygen, your heart beats faster, your ... |
Why are AMD's GHz considered slower than Intel's | Clock speeds in and of themselves are not all encompassing to a processor's performance. How "fast" a processor is can be a little subjective because different features are more apt to different environments. For example, a processor you would use in a database environment may not work as well for an application that i... |
Does re-boiling water really change the taste? If so, why? | Yes, it is true that there is dissolved air in water that is removed by boiling . I don't know whether it affects the taste of tea , but flat water certainly feels different from water with lots of dissolved air. I have heard a similar thing that you should not even let the water get to a full boil, for the same reason... |
What are prime numbers used for? How are really large prime numbers calculated? | There aren't actually a large number of uses for prime numbers. For years they were studied for interest's sake, rather than because anyone knew what to do with them. Some uses have been discovered however. The check digit in an ISBN is calculated in such a way that exploits the fact that 11 is prime. They are also use... |
Why is the shake camera so popular now? (Movies / TV) | It gives it that documentary feel where the cameraperson is part of the action. Watch some war documentaries filmed in the actual battles and notice how much camera shake they have.Because cameras have gotten smaller, lighter, and better over the years, so it's become easier to use the hand-held option if a director wa... |

Is there a scientific reason that the Northern Hemisphere is shown at the top of maps? | Early maps pointed in all sorts of directions. Some navigators used the North Star as a reference point, which tended to put special emphasis in that direction. Conventions stabilized over time, because of political and technological influences. Al Jazeera wrote a [pretty good piece about this question] if you don't mi... |
Why do you get a bump on your head when you bang it, but that doesn't happen anywhere else on you body? Or does it? | It can happen anywhere else. The skin on the scalp is much thiner than on most other parts on your body, and the bump can only swell outwards because inwards there is no room due to the skull. I have a bone anomaly on my left arm and I bumped it once and it was really swollen like a bump on the head because I don't hav... |
Why don't homeless people go get whatever free benefits are available? | Without getting political or opinionated: 1) There aren't as many benefits out there as it may seem -- the system is pretty saturated. 2) Many homeless people are also mentally ill, which inhibits their ability to think rationally, and do what they need to do to get benefits 3) Many of them do look for jobs, but most e... |
Why is it that unhealthy food tastes so good? | Foods that have high concentrations of fat and sugars were scarce on the african plains our species grew up in.

Does the universe have a finite dimension? | As far as we know, the answer to your question is No. There's a limit to how far we can "see", and I 've put "see" in quotes because the limit isn't just about seeing, it's about how far *any* information could have travelled to get to us. This limit is based on the speed of light and the age of the universe, and how f... |
Why are public bathrooms gender specific when most people spend their life sharing a bathroom with all genders? Why aren't port-a-potties gender specified? | The bathrooms at home are usually meant for only 1 person at a time, and any extra people would be your own family.

Why isn't the third rail extremely hot? Isn't it essentially a metal bar with an electric current running through? | Current only flows though the third rail when there is a train passing it. Otherwise the loop is not closed so no current flows. In addition there is not much current flowing as the voltage is quite high. Also the third rail is quite thick so there is not much resistance.For the same reason the wires in your wall don't... |
How does the ELO rating system work? | Basically, one's rating changes based upon rated games against others with a rating , and is an indicator of how likely one is to win against another player.

How are we able to replay songs we know in our mind on demand, with usually the singer's exact voice and main instruments in tune? | On average, we can't. If I asked someone to transcribe the vocals and instrumentals of a song in sheet music form, they'll realize that the version they have playing in their head is extremely vague and lacking.You probably aren't. Remember that you're not checking the "playback" against the original recording - you're... |
Why some banks offer free use of any ATM? | Because this allows them to not invest in their own ATM infrastructure and stay competitive with banks that have. Otherwise, their customers would experience an increased cost for choosing them over a bank with a large network of ATMs since banks essentially never charge for use of their own brand ATMs.It's a good sell... |
Why do people drive by accelerating and then braking, instead of maintaining a more constant speed and deceleration naturally? | Your instructor is correct. That is the right way to drive, and is a lot more efficient and kinder on your car. But maintaining a constant speed is a challenging skill you have to learn, and not everyone does so. You are also right that you should drive far enough ahead to deal with almost all issues by coasting down a... |

They have scripts in front of them so when situation X happens they are supposed to say Y. |
Up arrow notation like in Graham's number. | When you multiply two numbers , you're really just adding m to itself n times. For example: * 4 x 3 = 4 + 4 + 4 = 12. The Knuth up-arrow notation was developed to make very large numbers easy to deal with. To get to Graham's number , let's first look at what an exponent is. m^n is m times it self n times. * 3^3 = 3 x 3... |
why do people with downs look similar | Yes, those differences in appearance are caused by one genetic abnormality that causes all the other symptoms of Down's syndrome. If the other symptoms of Down's Syndrome made it easier to live life as humans, attract a mate and have children, then it could become part of what you could call 'evolution'. Persons with D... |
How much metal does it take to produce sparks in a microwave? | As I understand it's not so much the amount of metal but more the shape of the metal that decides how much sparks are created. Small thin metal corners and creases can't handle all the energy so they release arcs which will set fire to your food. If you use a really smooth piece of metal it might actually be perfectly ... |
Why a 2.2GHz quad core is better than a 2.7 GHz dual core. | If you think about a CPU as a supermarket checkout a quad core processor literally can process more information at one time than a dual core .Eh, this isn't exactly ELI5ish but it also needs to be pointed out that clock speed does not necessarily determine if a processor is 'better'. The 2.2GHz quad core processor may ... |
Will prices rise forever? | In theory, yes. As more people are born and enter thework force and as more money is created in various ways, this leads to inflation which is why prices rise over time.

Why do the Crips and the Bloods hate each other? | The Crips were formed to help protect the Black community from opposition back in the 60s/70s. As time went on, however, their focuses slowly shifted from being the benevolent force to being one that promoted drug dealing and making loads of cash . As a result, the Bloods were formed as a counter force to keep the Crip... |
How does a black hole evaporate? | So, in theory, pairs of particles a and antiparticles are always popping into existence all the time and then annihilating themselves all the time. This I'd cool because there's no net change in energy.\r\r\rHawking radiation is when this happens in the very edge of a black hole and one of the particles is on the outsi... |
how Gruber/ObamaCare is accused of gamed the CBO | In the weird world of Washington accounting, things are either a federal tax/spending, at which point they go on the federal books , or not.

What goes on in our mind and body when we meditate and why some people hallucinate when meditate for a long period of time? | Our brain uses a lot of unique tricks to interpret our perception of the world around us. Our eyes for example can only see details in the very center of our field of view. The rest of your sight is good at picking up movement quickly but not detail. The reason you don't notice this is because your brain filters throug... |
The Argentina- U.S. Debt Situation | It is not is the short answer. It is a political bargaining chip.

How did people move before Uhauls? | Throw everything you can fit into whatever vehicles you have at your disposal, and then make more than one trip if you need to. If you don't want to make multiple trips, then you would either need to find someone else with a large vehicle or pay someone to do so, whether that be a private individual or a company who ex... |
How is the doctrine of adverse possession even a thing? It seems like a terrible, unfair and unjust doctrine to have in the legal system. | A few reasons: First, how would you like it if someone showed up with some evidence that back in the time of Henry VIII , your ancestor took their land from their ancestor? If you don't validly own land, any sale of it is invalid. So, that would mean land which has been in your family from the 1500s suddenly goes to so... |
Why do humans not enjoy belly rubs as much as pets? | Keeling over to accept a belly rub can be a sign of submission in dogs. Often a very submissive dog will expose his belly to someone without prompting. But aside from that, it's a tough area for them to scratch and they're not "ticklish" like many of us hairless humans are. So a belly rub scrubs the hair against their ... |
Why is the word "cunt" used and accepted significantly more in the UK, Ireland, and Australia than it is in the USA? | It is still a vulgar word in the UK, Oz and Ireland but much less taboo because it is used more frequently and in a wider variety of situations. Yes you can still start a bar fight by aggressively calling a guy a cunt but I 've heard rugby lads say "he's a good cunt", affectionately, about a mate.Probably because it is... |
How are game shows able and willing to give so much money on a weekly/daily basis? | Game shows last only 40 minutes at best, the rest of the hour is devoted to ads sold in 30 seconds or less for tens of thousands of dollars. 20 minutes worth of ads can, at 30 seconds each, bring almost 1/2 a million bucks if each slot 30 second slot is sold for $10 k, but that is a lot cheaper then they normally are',... |
How Quantum Entanglement works, without math. | Without the math, the phenomenon is pretty esoteric and potentially unfulfilling. Essentially, you take two particles and bring them together under very specific conditions. The conditions needed are very complicated, but suffice it to say you can manipulate the conditions so that your two particles become "entangled".... |
Does the pitch of a musical note change over time due to changes in climate, temperature... | The pitch of a note made by a physical instrument changes over time, yes. An easy way to see this is with a string instrument. The string is held under tension such that when struck somehow, it vibrates at a particular frequency . If the instrument is tuned in a warm environment and then played in a cold one, the strin... |
How are movies shot in public places and not having any noise of the people standing around the sets | They have $3,000+ microphones that can pick up certain frequencies on top of that these microphones have a certain decibal level, this means that the microphone will only pick up Human voices at certain volume and they set this range before they record Example:Shooting a movie in a crowded party.Director would cut out ... |

the system of checks and balances the USA has, and why/how it works? | The system of checks and balances is a way to make sure that no part of the government becomes more powerful than another.

Basically, what che... |
Why am I able to multiply by 9s with my hands? | the sum of all digits when you multiply nine by another number that is less than ten is nine.

Why dont humans sleep during the day, and stay up at night? | Our eyes evolved to see a color that many other mammals cannot see. That color is red. At night we cannot see any colors at all, as everything is sort of grey. Even the animals that have great night vision cannot see red. For humans the ability to see red makes being awake in the day better. We can see red berries that... |
How does American college football work? It seems like organizational chaos. | So, it sort of is organizational chaos. Universities form groups called "conferences" which become sort of like their league, and there are many leagues, since there are only 12 regular season games, and far more than 12 unis in America that compete at the top level. These conferences are somewhat analogous to the Euro... |
How is landfill stable enough to be used to make more land area? | The big issue when talking about the stability of ground is the density of the material.
