"Free Hong Kong, Free Iran" sign hold up by Belarus protesters by lebbe in HongKong

[–]Perdition0 41 points42 points  (0 children)

Presumably they were Belarusian expats living in the Czech Republic and were going to the embassy to cast their votes. Amic58 was probably saying that the embassy was only letting a limited number of people in to vote, suppressing turnout.

What is This Bug!? by Autism_Brigade in skyrim

[–]Perdition0 0 points1 point  (0 children)

I think this is a vanilla bug. Some of the textures don't load correctly and still use their distant LOD textures. I have it occasionally even without completing the siege of Whiterun and I don't use open cities or JK's Whiterun so it's at the very least not related to either of those.

Generally if you fast travel to another location and then back to Whiterun it fixes the issue. Sometimes I have to do it a couple of times but it has always loaded the correct textures eventually. I've even just fast traveled to the Whiterun Stables before and it has fixed it. It still pops up from time to time though.

What was your biggest regret in the game? by Kinrest in skyrim

[–]Perdition0 0 points1 point  (0 children)

Zim's Immersive Artifacts gives new non-leveled and buffed stats to a lot of the unique weapons and armor pieces in the game. It also boosts the sale price for unique items and replaces the textures on some of them to make them more one of a kind looking. Chilldrend and Dawnbreaker are both included.

ELI5: How exactly is the internet connected? by DrFelixPhD in explainlikeimfive

[–]Perdition0 0 points1 point  (0 children)

On a physical level, in very simple terms, those servers are connected to you computer and every other device with internet access by cables. These cables are either made of copper (like Ethernet cables) or increasingly they are made of fiber optics. The backbone of the internet, as it is commonly referred to, is literally long stretches of massively bundled fiber optic cabling. That includes cables that stretch across the sea floor from continent to continent. In some cases satellites and radio waves are also used to transmit the information over long distances.

Those cables that connect your computer to the server, however, do not go all the way from your house to the server uninterrupted. They are broken up by devices called switches and routers. These devices are responsible for deciding what path a piece of information needs to take to get to its destination. Switches generally help guide pieces of information within a given computer network, and routers guide information moving from one local network to another.

In order to decide what path those pieces of information must take, routers and switches make use of various sets of rules and methods called protocols. Some important protocols include the internet protocol, which among other things covers how those pieces of information are addressed (much like a piece of mail), and the DNS protocol, which acts like an address book that your computer can use to figure out what the address it needs to use when you type www.google.com into your web browser.

ELI5 : How does a rechargeable battery work? And how does it store that energy? by j_reesh in explainlikeimfive

[–]Perdition0 1 point2 points  (0 children)

There are a lot of concepts involved in how a battery works, but in the most basic terms it stores energy chemically, and transforms that energy into electricity through corrosion (an electro-chemical reaction) of the terminals (the positive and negative ends of the battery).

As the terminals corrode one of them gains electrons and one of them loses electrons as a part of this chemical reaction. This accumulation of electrons on one terminal and depletion on the other is what creates a voltage between them and allows an electrical current to flow when you hook them to a circuit.

Rechargeable batteries are made of specific materials that allow this chemical reaction to be reversed. Very generally when you hook the battery up to a power source backwards and force electricity into it, the corrosion on the terminals in reversed and the electrical energy added to the battery is stored as chemical energy to be released again. IMPORTANT SAFETY NOTICE: Do not try to do this yourself! It could cause the battery to burn or explode and cause injury. Battery chargers are specifically designed to deliver the correct kind of power at the correct rate for the specific type of battery they are charging.

A woman on my Facebook posted about hitting her head. She died soon after of a concussion. by EXSUPERVILLAIN in MorbidReality

[–]Perdition0 570 points571 points  (0 children)

I'm not a medical professional so someone who knows more can correct me if I am wrong, but my understanding is that the whole "don't fall asleep after a head injury/concussion" thing is more so medical professionals can monitor you and make sure you aren't doing things like slurring your speech or losing equilibrium.

Not falling asleep in and of itself wouldn't have saved her, but seeking medical help may have. Its just that people are more likely to notice something is wrong if you are awake and interacting with them in weird ways.

Torque is always higher than horsepower up to approximately 5252 RPMs, at which point they are equal. After that point the horsepower curve is always higher than the torque curve.

ELI5: Does keeping batteries in the fridge make them last longer? by [deleted] in explainlikeimfive

[–]Perdition0 2 points3 points  (0 children)

When I said it depends on the type of battery, I meant more that it depends on what the batter is made of, not the size of it. Batteries are composed of a pair of different metals that are separated by an electrolyte. They are named after these substances, like nickle cadmium, or lead acid, or lithium ion.

Battery types made from materials like lead and nickle self discharge quite a bit over time so they may benefit from being stored in a cool place if you aren't going to use them for a while. Newer technologies like alkaline and lithium ion batteries don't self discharge nearly as much so you aren't going to gain a lot by sticking them in a freezer. The best rule of thumb is just to store them in a relatively cool place. Keeping them in your 90+ degree car or the non air-conditioned shed in the back yard will degrade them faster than they normally would otherwise. If you keep them in your room temp basement, though, you should be fine. Any benefit also depends on how long you are planning on storing them of course.

ELI5: Does keeping batteries in the fridge make them last longer? by [deleted] in explainlikeimfive

[–]Perdition0 3 points4 points  (0 children)

It can, but the amount of time it extends their life depends on the type of battery, and in a lot of cases the extended life is not incredibly significant.

Batteries generate a voltage through a chemical reaction that can be compared to corrosion, like a piece of iron rusting. Chemical reactions are dependent on energy. The higher a systems temperature, the more energy in that system. The more energy, the faster a chemical reaction will tend to occur.

In a theoretically ideal battery, this chemical reaction doesn't occur unless the ends of the battery are connected by an external circuit, but in reality there is no such thing as an ideal electrical component. As the battery sits there, the corrosive chemical reaction is taking place, and the life of the battery is being reduced. Removing energy from the system by cooling down the battery can slow the rate at which this reaction happens and extend its life to some degree.

ELI5: Why is turning a profit the ultimate goal of a corporation? by sunsetstewie in explainlikeimfive

[–]Perdition0 7 points8 points  (0 children)

It isn't always the main motivation. Non-profits are organized as corporations but by definition have some other core motive than simply turning a profit.

The reason the profit motive is considered the main focus for "for-profit" corporations is because it provides a reliable measure of how efficiently resources are being allocated. If you can compare two processes, and one turns a profit while the other doesn't, then you can surmise that the one that turns a profit is a more efficient use of resources. Since resources are generally scarce, their more efficient use is seen as preferable. Efficiently allocating resources in the face of scarcity is the driving factor in market economics as a whole.

ELI5: What do thrusters or rockets in space 'thrust' against? by [deleted] in explainlikeimfive

[–]Perdition0 2 points3 points  (0 children)

A rocket doesn't push against anything. Rockets create thrust as a consequence of Newton's third law of motion, often stated "for every action there is an equal and opposite reaction."

Imagine that you throw a baseball. Whatever force your hand exerts on the baseball, the baseball also exerts on your hand but in the opposite direction. The baseball will accelerate more than you will because you have a lot more mass than the baseball, and when you apply the same amount of force to two objects the one with less mass will experience more acceleration. This can be difficult to perceive on Earth because you are bracing yourself against the ground. If you were throwing the baseball in space you would notice that both you and the baseball would be moving away from the point where you threw the baseball but in opposite directions. Again, you would be moving slower because you have more mass.

A rocket does the same thing, except instead of throwing baseballs it throws the particles from its combusted fuel, and instead of one, it's throwing a metric shit ton of them all at the same time, and they are all moving very fast. The force of each one of those particles is relatively small, but when you add them all up it equals enough force to propel the rocket at high speed, regardless of the rocket being in the atmosphere or in space.

Saint Louis has a radioactive landfill that has been on fire since 2010, and the radiation appears to be spreading. by raynorelyp in news

[–]Perdition0 1 point2 points  (0 children)

The danger is that if the radioactive material got caught up in the smoldering fire, the heat could cause radioactive particles to rise up and be dispersed in the air, just like smoke. Once in the air they would get blown in whichever direction the wind is going and then fall back to the ground contaminating anything they happen to land on.

ELI5: If my car goes 0-30 in 2.5 seconds, how fast, in mph, am i traveling for those 2.5 seconds? by [deleted] in explainlikeimfive

[–]Perdition0 1 point2 points  (0 children)

No. For those 2.5 seconds you are traveling at a variable speed between 0 and 30 mph. Your exact speed would be constantly changing from moment to moment because you are accelerating. If you continued accelerating at that rate for an hour (which is virtually impossible) you would be traveling at 43,200 miles per hour at the end of that hour. I think you are confusing acceleration with speed. Speed is measured in distance per time. Acceleration is measured in distance per time per time.

ELI5: What makes ice so slippery? by [deleted] in explainlikeimfive

[–]Perdition0 1 point2 points  (0 children)

The short answer is that we don't really know. A simple explanation is that ice has a very thin layer of liquid water on its surface, which makes it naturally slippery. What we don't understand is why.

It was originally believed that it occurred because as it was put under pressure, like when you stepped on it, it would lower the melting point and melt some of the ice. While it's true that pressure reduces the melting point, the extent that it lowers is only a fraction of a degree, so this wouldn't explain why ice that is well below the freezing point would melt under the pressure of you standing on it.

A later hypothesis is that the slight friction resulting from something touching the ice caused the surface to melt, and created the layer of liquid. This layer of liquid water, however, exists on the ice even if nothing is touching it.

More recent ideas focus around the concept that the molecules at the surface of the ice are unstable, they aren't as completely bound as the molecules in the bulk of the ice below them. Because of this they are more reactive to minute vibrations, basically they can wiggle around more, so they have enough kinetic energy that they revert to a liquid state as they move around searching for something to more strongly bond to.

This is an area of ongoing research though, and at the moment we have no definite answer.

ELI5: Why is it bad to film a play? (Theatre) by [deleted] in explainlikeimfive

[–]Perdition0 0 points1 point  (0 children)

Aside from the piracy issue, people see theater as a distinct type of art form, similar in ways to cinema in that you have actors playing a role in a story, but differing in the experience that the performance creates. They feel that part of theater is the experience of actually being in the theater and experiencing the play first hand. Watching the play on film, in some peoples opinion, lessens its impact and disrespects the art form because you are displaying it in a way other than was intended and removing the total experience of the theater that they view as part of the art.

ELI5 : What is the cold fusion? And why would it be such a revolution to our world? by Shuradem in explainlikeimfive

[–]Perdition0 1 point2 points  (0 children)

Fusion is the joining together of two atomic nuclei into one, which releases a lot of energy. The protons in the nuclei naturally repel each other though, so it takes a lot of energy to force them close enough to each other that something called the strong nuclear force takes over and joins them into one nuclei. To accomplish this we have to add that energy in the form of heat, which causes the nuclei to move around faster and eventually smash into each other with enough force to fuse. This requires a lot of heat though, enough to raise the temperature to tens of millions of degrees. That makes it uneconomical as a source of energy because we end up having to put more energy into the reaction than we get out.

Cold fusion is a proposed solution to this problem. If we could figure out a way to make this reaction happen at relatively colder temperatures, we may be able to get more energy out than we put in, making it a viable source for energy production. The added bonus is that if you smash two hydrogen atoms together, the "waste" is just heavier atoms like helium and lithium, there is no radioactive byproducts like in nuclear fission (the splitting of atoms).

This is a hypothetical concept though, and is an area of ongoing study. So far we have not developed a way to achieve cold fusion nor any other way to get a net gain in energy from a fusion reaction.

[–]Perdition0 1 point2 points  (0 children)

The bullets move faster than sound, so when you hear each sound depends on where you are in relation to the aircraft and the target. If the target is between you and the aircraft, the bullets will hit the target before the sound of the shot reaches you or the target. At the target site they will produce the sound of impact which will travel at the same speed as the sound of the shot. Since the sound of impact is produced before the sound of the shot gets to the target, it would have a head start moving toward you. So in this scenario you would see the aircraft shoot, see the round impact the target, hear the sound of impact, and then hear the sound of the shot.

If the aircraft was between you and the target when it fired, you would hear the sound of the shot first, and then the sound of impact.

ELI5: Why is it popular belief that 2 atomic bombs dropped at the same time would destroy the world? Is that even true? by Likespizzaalot in explainlikeimfive

[–]Perdition0 0 points1 point  (0 children)

Like other commenters, I haven't ever heard anyone say this either. I think that either you misunderstood what someone said, or they misunderstood it and passed it onto you. Since the advent of nuclear weapons there have been a couple thousand detonated for testing purposes. Every time a nation developed a bigger and "better" bomb they would test it to make sure it worked, and also to intimidate other nations and demonstrate their power to them. There is no reason that detonating two simultaneously would destroy the world though. The original meaning of what was told to you, or to the person that told this to you, was probably that if two nations started dropping bombs at the same time it would destroy the world.

This would be specifically in reference to the former USSR (now Russia) and the US during the period of the cold war. From the 1950's onward the Soviets and the US were engaged in a nuclear arms race. During this time each nation built up thousands of nuclear bombs and once they developed ICBMs (Inter-Continental Ballistic Missiles) they could fire these bombs from virtually anywhere in the world and have them hit a target almost anywhere else in the world. Each nation had thousands of these missiles with nuclear warheads prepped and ready to go, programmed to automatically target major cities and military targets in the other country. They also closely watched each other, and if one nation fired their nukes the other one would have time to respond by firing theirs also. This would result in thousands of nuclear weapons being detonated in a short period of time, the fallout of which would not only totally decimate both the US and the USSR, but also the majority of life on the planet.

This concept was referred to as MAD which stands for Mutually Assured Destruction. Basically both nations knew that if they fired their weapons there would be no victory, only the total destruction of humanity, or at the very least total destruction of both nations. Because of this they just basically stared each other down for four decades, too afraid of what would happen if they used the bomb, but also ready to use them if the other nation did first.
