Why is it that say, at 11pm in the Summer, it would be more/less dark, than it would be at 11pm in the Winter, assuming the skies are cloud free those days. | The earth revolves around the sun. Think of that path as the outer edge of a flat plate. If the earth's axis of rotation were at a 90-degree angle to the plate, this wouldn't happen. However, the axis is tilted roughly 23 degrees. Therefore, when your hemisphere is on summer, you're pointed slightly towards the sun . T... |
Why do hotels use two flat sheets instead of a flat and a fitted sheet when making the beds? | Efficiency.

Why do volcanoes contain lava, or do they make it by melting rock or something else? Maybe better asked as, where does lava come from? | Molten rock is what is in the centre of our earth where it's very, very, hot. Pressure within the volcano builds and eventually erupts. No one "makes" lava, it's a natural product[Within volcanoes is a crack in the crust of the Earth.] This causes magma to flow up until the volcano. It comes from the mantle of the Eart... |
Why does rendering gameplay in video editor take significantly more time than recording live gameplay? | Rendering a video is doing more than just putting images back to back and then creating a video that puts those images on the screen.

Why are human babies completely helpless for the first few years of their lives but certain animal babies are already running around within hours of birth? | It's one of the negatives of our evolutionary tract. One of the biggest advantages we have is that we're bipedal, i.e., we walk upright on two feet. It allows for a lot of really cool things. We have a higher vantage point than most animals our weight, we can use our hands freely while running, our head is directly abo... |
Tumblr. I've only seen it through Reddit's eyes. Is it really a place for pansexual, wizard, reverse-rape feminist, eagle gendered, proudsexuals? | Tumblr's what you make of it, same as reddit. It's just a blogging platform rather than a bunch of forums, but it's still all about what you choose to do with it - which subreddits you join, or what kind of tumblr blogs you follow. If you deliberately seek out the fringe cases , then you can have the eagle-gender tumbl... |
Why is it that the deeper you go down in an ocean, the colder it gets, yet the deeper down you go underground the hotter it gets? | Deep in the ocean the water has been down there for a very, very long time. Ocean currents take ~~centuries~~ a thousand years to cycle, and there isn't much for heat sources down there. Around geothermal vents the water can get super-heated because it's under so much pressure that the boiling point is increased, water... |
Other than efficiency, what does pumping premium gas instead of regular do? | It doesn't improve any of that. You are probably imagining it. Basically, it's possible to do more aggressive engine design if you only use premium. If your car doesn't say it uses premium there is no benefit. |

How can a 16kW evaporative cooler cost less money to run than a refrigerative cooler rated at 8kW, when you are charged in kilowatt hours? | In this case, you are looking at Watts with two separate meanings. The output of the cooler is using kW as a unit of heat, where you 'd often see something like BTU/h or something. You're also looking at electricity costs in terms of kWh. An evaporative cooler uses the "cold energy" in the incoming water to chill the r... |
how do apps such as snapchat make money, even though they have no cost and are ad free? | In a word, users. These are a class of businesses that depend on 'velocity' and 'critical mass'. They have to keep growing their user base and hope they can stay in business long enough to capture the most people. If they get enough people quickly then they can start selling ad space or personal details of their user b... |
Why can we not remember anything from when we were babies? | Compared to other species, we are kind of born a little early in development. This is because our massive heads would wreck our mom's vaginas if we were in the womb any longer. Babies are basically crying, pooping blobs for a year while our brains and bodies develop enough to walk and talk. It's not really important fo... |
How do satellite TV companies disconnect viewing cards? | The satellite box receives a very high bandwidth stream of digital packets. There are data packets for each channel and control packets. Mixed in the control packets is occasionally a packet that says "New authorization data for card #345375793 = {list of channels}". That's why if the card looses it's state you get "wa... |
Why a quarter, nickel, and rechargeable battery in my pocket randomly got really hot and scorched the pocket of my pants? | You completed a circuit in your pocket, allowing electric current to flow. The coins have some resistance, so the current passing through them dissipates some power across the coins. That power dissipation is observed as heat. Same thing happens if you connect the two terminals of a battery with a wire. With math, P=V^... |

How do scientists find the age of a living tree without actually cutting it down and counting the rings? | You can take a very small hole saw drill bit and take a sample that way.By comparing it to other trees of the same type that have already been cut down and had their rings counted. It's an estimation based on the size and developmental progression of the tree. |
Why do the doctors make us read characters off a mirror during an eye exam? Why not just have it in front of us? | Looking at that eye chart in a mirror that's reflecting the actual chart mimics the 20-feet distance that is needed for such tests. In other words, not all exam rooms have a 20-foot distance to measure/evaluate your vision. It's a useful work-around for a small exam room. |

You don't understand because you ... |
Why do videogames have the option to invert the vertical movement for mouse or joystick, but not the horizontal directions? | Plenty of games have both. That said, the X axis inverted makes no real sense while Y axis does. The exception is in some third person games, if you feel like you're actually controlling the *camera*, then moving the *camera* to the right will result in seeing more to the left of your character. |
How/why does it start to get darker as it gets closer to the end of Daylight Saving Time? | Okay, imagine a ball with a pencil stuck straight through it and a bare light bulb .

First hold the ball so that the pencil is aiming straight up and down, perpendicular to the floor. Now tilt the bal... |
What does the White House Chief Strategist actually do? | Wikipedia says that it is the "Senior Advisor to the President.".

Why does our body have such adverse reactions to pollen, thus setting off allergies? | It's actually just your immune system overreacting! Your immune system is designed to look for things in your body that don't belong, and then clear them out in some way. For people with allergies, the immune system incorrectly reads the allergen as something that is dangerous to you. It then sets off a bunch of reacti... |
Can someone explain why the right-hand rule for cross-products in vectors is true? | It's an arbitrary convention. If we agreed to have the result of cross products point in the opposite direction, all the math would work out in exactly the same way. |
Is the Flat Earth Society a joke or are they serious? | I expect some are serious. They think the experts with all their fancy degrees have confused themselves, or there is some kind of motive for conspiracy. I expect some 'members' did it on a lark, or gave a membership to someone as a joke, or may be trolling or griefing.Some do, and basically attribute it to a massive co... |
Why are human races like Asian and Caucasian not considered as a subspecies but animal's like cats (example) say Persian and Maine Coon are considered subspecies? | They're not.

What is the "Olber's Paradox" and the theories behind it? | It is an argument against the universe being infinitely big *and* infinitely old.

Why do most professional sports(US) require 4-7 games to determine the winner in the Finals(or equivalent), but football needs only one? | Football is really physically taxing, since it's a full-contact sport. Even playing once a week, the injury rate is high and the rate of long-term problems is higher than in other sports. If the NFL used a best-of-7 format instead of single elimination, then either each series would take a month, or the players would b... |
How does deal or no deal work? I've watched the show but I have no clue what is going on. | Each box contains a different amount of money.

Why did they create a cheek and tongue cleaner when I can just use the toothbrush itself? | I've never read a study that said a dedicated tongue cleaner was more or less effective than the brush, but I imagine it's simply a marketing thing -- why sell you one tool when I can sell you a two-in-one tool, or a three-in-one tool with little to no additional engineering and manufacturing? |
Why do older men start sprouting hairs from random places? | 46 yo. You will go through several puberties.

Which is better for the environment: aluminum cans or glass bottles? Why? | Making aluminium from raw materials is a complex process. Once made the metal can be melt down and reformed without losing any quality. This process can be repeated over and over again. Along with the energy savings, recycling aluminium saves around 95% of the greenhouse gas emissions compared to the ‘primary’ producti... |
Why are radiators often located beneath window shelves? | you are almost right - it is usually the coldest spot in your room. But that also means, that this is the part of the room that is the hardest to heat. If you'd put the radiator at the other end of the room you'd have a very warm and cozy part of the room and the freezing part of the room right next to the windows. And... |
What is/was the big deal with Indian gaming tribes in California? | I'm going to go out on a limb and presume its 'gambling' tribes were talking about.

Their revenue is in the billions, theres a lot of corruption, and a lot of the employees... |
Why do fluorescent light bulbs flash a few times before they eventually light up, where as regular bulbs switch on straight away? | Fluorescent lights work by energizing the gas inside until it forms a plasma and allows an arc of electricity to pass through, heating the gas further and creating light in the process. However, before the entire bulb is at a high enough energy, there might still be a path for the arc to pass through , but it can be br... |
Do fish need freshwater like other animals do to survive? | Fish need water, yes.

Why can I eat a lot of hot pizza, but only a little cold pizza? | It's most likely nothing more than a psychological effect based on the fact that you likely find the fresh pizza more appealing.

How do boogie board tablets/eWriters work? | First, a note. An "eWriter" is a device you can take notes on by writing on the surface itself - this definition does not specifically mention how this can be accomplished, meaning one eWriter may potentially achieve this goal completely different than another.

How come when I stream a live feed of something to my computer, it's often a couple minutes behind what I would see if watched it on the TV? | Mainly because your cable connection is a more direct link to the content.

Why is it that singers lose their accent when they're singing? | Techniques for proper singing tend to counter accents. You'll still hear an accent on consonants but since singing is mostly in the vowels, and there's ways to sing vowels that are better for one's voice and sound than other ways, a singer will usually go to that sort of "universal" singing accentSome counter artists w... |
-What causes someone to pass out? (not alcohol or drug related?) | More often it's a *drop* in blood pressure. Also, what's called a vasovagal syncope.

They operate out of countries that allow their business practices and, since they... |
Why is Dzhokhar Tsarnaev, the captured Boston Bomber, not going to be read his Miranda Rights? | I have not hear any official statement that they are not going to read him his rights, only that they have not read them yet, things take time and they have time to do this right. |

How does starting a sentence with a short filler phrase like "yeah, so" give you time to think of an answer as opposed to just being silent for that second? | You'll have time to think in both cases. But if you fill the time to think with something, even empty phrases, you will get the attention and lesser chance of someone interrupting you. |
Why a 3:1 differential (in a car) would provide less torque than a 4:1 | I believe the difference is the torque which is applied to the tires. Your engine will still rotate the input shaft at the same rate, but the higher the gear ratio the higher the torque will be. This picture might help: _URL_0_ You can imagine it exactly like a bicycle. The input shaft would be the petals, and the outp... |
Why does the electricity in some cars get cut off when starting the engine? | The starter motor draws a lot of current, enough current to reduce the voltage output from the battery. Since electronics sometimes do wonky things when operated at lower than necessary voltage, it's better to just disconnect them for a couple of seconds while the car starts. |
Why does the USA object to the Palestinian State being recognized by the UN despite its formal position in favor of a 2-state solution? | Because they want the Israelis and Palestinians to agree on the borders before they recognise it.

each decade of the 20th century had a distinct character ie the 60s and hippies, the 80s and hairspray... What about the 19th century? Was each decade defined by a certain style/music? | Back in the day, cultural trends would move more slowly. We didn't have TV, Radio, cars & airplanes to spread pop culture & then replace it with the next big thing.

What would happen to a deep sea fish that is used to thousands of pounds of pressure that was brought to the surface. | It dies. Deep sea creatures sort of explode when brought up from the depths.

How do tail numbers on planes work? | The numbers afterward are like a license plate. There's an FAA registry where you could look up owner information from a tail number. Normally control towers refer to planes by the portion that follows the N . Some controlers will further reduce that to the last few letters . They always use the phonetic alphabet, so t... |
What is the process that will happen when the current queen dies? | The rule is that the monarch is never dead, because the crown instantly passes to the heir. This is also why the British flag is never flown half-mast, because that would imply the monarch is dead. _URL_0_! There will be an official coronation, but that's a formality. Same as if the President of the US dies; the VP ins... |
why do most Asian cultures value age and seniority so highly, yet most European cultures do not? | I think it's partly because most Eastern Asian cultures have strong Confucianism roots which values filial piety. Just like you said, these values are prevalent in the language as well where we use specific honourifics depending on one's status and relationship.Western culture is more inclined to economics and business... |
What are automation tools in the context of IT and software development? | You can make a case for any scripting language as being an "automation tool." They can be used to automate unit testing code, and can be further used to drive automation for larger test efforts. The exact tools you use will vary depending on what you're testing, and sometimes the environment as determined by your emplo... |
Does it require an elevator more energy to go "down" empty than to go "up" full? | Depends on the sizing of the counterweight If the counterweight is sized to be *exactly* car weight + 50.0% of the rated load then it will take the same amount of energy to go down with 0.0% load as it takes to go up with 100.0% load If it's not perfectly sized, then which ever involves lifting more weight will require... |
the Falcon9 landing. Why is it cool? What does it get us closer to doing? | As you can probably imagine, one of the most expensive aspects of space travel is building a rocket to get there.

Why is the issue of forged tweets not used to suspend/ban people from Twitter (i.e. Milo Yiannopoulos, latest high-profile case)? | I'm confused about how this relates to Milo Yiannapoulos at all. That article certainly doesn't mention him, and as far as I know they didn't have an overly good reason for banning him in the first place. I do agree that Twitter should institute a policy regarding forged tweets and hacking, I imagine that the reason th... |
What prevents plants from growing beyond a certain height? | A pant usually grows taller so it can outgrow all other plants and catch the most sunlight, which it needs. However, growing and keeping all those leaves healthy and hydrated costs a lot of energy, which is why a tree loses its leaves in winter, when it's not energy efficient to keep its leaves alive. Now, the taller a... |
Why do young people need more sleep? | This is because young brains consume much more energy. An adult brain uses about 20% of the total energy of the body, mostly to support mental activity and cell repair. Children's brains however, are not only doing this but in addition their neurons are growing and moving at incredible rates, creating new pathways and ... |
Questions about the war in Afghanistan | I can help you with the last 2. The truth is, they can't do much.

How did shipbuilders raise the masts on ships of the line, eg. HMS Victory | You hold one end of the mast in place, then attach a rope to the other end . Run the rope over a pulley on the top of a second mast, and then pull the rope. The rope will pull up on the mast, pivoting it until it's vertical. The second mast does not need to be as tall as the mast you're uprighting, but it helps. The ta... |
did alligators exist the same time as dinosaurs and if so what makes them different from them? | Alligators first appeared ~37 million years ago.
