The oldest cartridge games (like for the Atari 2600) were programmed exclusively in assembly language. For the 2600 specifically, programmers often kept track of how many cycles their commands took in order to avoid overly long functions that would cause the video output to break. The book *Racing the Beam* goes into e...
Iirc it's a set of magnetic zones with different directions, North and South poles, that the card reader can translate into numbers, like binary to regular text.
Most bumpers have black plastic and rubber on the edges; that's what scrapes against the barricades.
Warfarin and other drugs are metabolized (broken down) into active or inactive compounds by enzymes in your liver. Grapefruit and other foods contain substances that can inhibit the activity of these enzymes, stopping the metabolism of these drugs. It can either lead to dangerously high levels of the drugs remaining in...
those are called 'intrusive thoughts' and are usually linked with anxiety/stress/ocd. i can't provide anymore detail than that but if you're having an uncomfortable amount of them (im pretty sure everyone gets SOME form of intrusive thoughts at least some of the time) you can try to start meditating regularly.
Trains mostly move big heavy loads that would be inefficient to move by trucks and planes. Trains move oil, coal, cars and trucks, raw steel, large machine parts, lumber, etc.. To my knowledge, we don't really use trains to move small, lightweight things like iPhones. It's better to move those by trucks and planes. A s...
The possible chromosomal combinations are: XY: biologically normal male XX: biologically normal female XXY: [Klinefelter Syndrome]( URL_0 ) biologically male who is sterile, but usually has no other problems XXX: [Triple X Syndrome]( URL_3 ) biologically female, the condition varies from no abnormalities or problems, t...
true random number generator doesn't exist. Computers work off equations meaning that any input you give it is going to return a predictable output. Current RNGs work by either having a really complex equation thats output effects the next input. This make the determining the output almost impossible for humans.
I'm not a doctor, just a paramedic, but this is my basic understanding of how it works. Not all drowning victim have water in their lungs due to involuntary laryngospasm. But either way, the lack of oxygen to the brain and other organs causes unresponsiveness and cardiac arrest. Once the person has been removed from th...
HIV is a particularly insidious virus because it attacks your immune system directly. It has evolved to be relatively blind to your white blood cells, making it easier for the virus to attack them and more difficult for your cells to fight back. Making a vaccine means taking a virus and killing it or weakening it, then...
When you first get a cut, the first thing that happens is your vessels in that area constrict to make sure microbes don't spread to other areas of the body. So this will cause bleeding to be slower than if your vessels were normal. Within minutes, a clot has formed and no new material will be able to come in. At this p...
Other than Pyongyang, North Korea is almost completely undeveloped. Before the Korean War, the northern portion of the Korean peninsula was much more prosperous than the southern portion. North Korea is a country that was a developed, industrial country that fell away from industrial development. Other than countless p...
[This is a picture of one thirteen-millionth of the night sky.]( URL_0 ) Most of the ~10,000 objects pictured are galaxies. Astronomers estimate that there are somewhere between 100 billion and 300 billion stars in the Milky Way, which is admittedly on the large side for a galaxy. Overall, the current estimate is 70 bi...
During the day, our mouths are constantly producing saliva which, to some extent, neutralises plaque. However, whilst we are asleep, we stop producing so much saliva which gives bacteria an ideal opportunity to feed on the plaque, giving us bad breath in the morning. That is also the reason we need to brush before we g...
much like a computer processor, our brain can never 'not run', so while we are in bed and our mind is not occupied in any activity, it starts remembering things since it's the only activity it can do. and sadly embarrassing things are the things we remember the most
Hairlessness allows us to regulate our body heat more easily. One of the main advantages humans have over other animals is our ability to run long distances, and hunt animals by tiring them out. If we were covered in fur, we would simply heat up too quickly and not be able to run for long. Evolution. Humans evolved in ...
Because various reasons were given before and during the war to justify British involvement such as alleged WMD's, Iraqi freedom and combatting terrorism. Now we know there were no WMD's, hundreds of thousands of Iraqis have died and are still suffering through civil war and terrorism is arguably a greater threat to th...
Royalties must be paid to you every time something sells, even if the business isn't making a profit. Equity means you own part of the company, which is only useful if the company itself is profitable or valuable. Let's say you invent a revolutionary form of artificial guacamole, and you want to try to sell it to a res...
Hi recently graduated biomajor here; when it comes down to the great marathon to come first it might come as a surprise that the first sperm is often not the one to fertilize the egg; rather it is the second third or even tenth to fertilize it after the first one weakens the eggs defences; the best example would defini...
You're mistaking "air" for "oxygen". We don't have many air pockets in our bodies. We do have a great deal of oxygen. We wouldn't survive without it.
The term "phobia" means an irrational fear or anxiety, as a psychological disorder. But some time in the last few decades, the term started being used a suffix in broader contexts, especially political and social, to denote a simple hate for something. This use of "phobia" arose long after the term anti-semitism was in...
Not all of them do, just LCD displays. The "L" in LCD stands for "liquid", and when you press on the screen, you are moving the liquid around, causing the color from the pixels to be messed up. Most smartphones don't have this issue as the glass is much stronger, so it takes a lot more strength to push it in. OLED and ...
The reason for this is that the electronics get smaller. Smaller electronics have less electric resistance, so they're able to do the same work without consuming as much power and therefore also without developing as much heat. Processing power has doubled without increasing power consumption every 18 months on average...
Do we? I don't feel like I do. I feel like I utilize both nostrils when I breath. Am I wrong? Short answer: we don't know why. It doesn't cause people to die and there is no money in developing drugs for it so no-one has bothered to research it. As for *how*, that we do know. Erectile tissue is found in 3 places in the...
A pencil mark is just graphite on top of a piece of paper. Think of it like something sticking to a frying pan. The eraser is like the spatula that scrapes it off with friction. Pen in actually is absorbed by the paper. Like water on a paper towel. You can't really remove it once it is there.
You're actually trying to move your center of mass backwards, since that's what causes you to fall. Your heaviest pieces are in your core, so you instinctually push your core in the right direction. Because your waist acts as a hinge, that then causes the top of your body to move in the other direction, and it's a lot ...
The small hole in the pic is for air to get inside the cup while you're drinking from it. This is why it's opposite where you put your lips. What this does is it lets the liquid come out smoother and faster.
Cooking meat doesn't add more energy into the food - what it does (in simple terms) is make it easier for the body to get the energy out of the food. This essentially means that it takes less energy to digest the food so the overall energy gain is greater - it also makes the food more able to be digested completely mea...
The main and vital processes in our cells are carried out by the help of enzymes, proteins which are sensitive to changes in pH and temperature. They work in a fixed temperature and pH value for a stable equilibrium. Changes in temperature would affect the enzyme activity and harm cells, throwing vital processes in the...
2 reasons. We find symmetry attractive because it's an outward indication of genetic health. If you have good genomes it is more likely your body will grow correctly, leading to nice even and symmetrical features on the left and right side of the body. Eyes that are the same size and distance apart, a nose which is cen...
They are not though. If by nutritional science you mean health gurus and vloggers, then it's because they don't know shit and all they do is perpetuate each other's bullshit. That's why you see the fads you described. If you mean the actual scientists and official healthcare regulations/guidelines those tend to be much...
Ossification, that is the conversion of the more flexible cartilage with bone, does not end until adulthood (and even then, much of it takes place well into mid adulthood, such as in the skull). At the same time, ligaments and muscles that keep joint movement in check grow stronger and less permissible of extreme movem...
Trash is just a folder where files go when you delete them so that you have an option to restore them if you deleted accidentally, they work just as any other folder. When you empty the bin, the file is really deleted from the file system perspective. Typically the data that were stored in the file is not erased, only ...
I have an extension to the main question, which would be that why does someone else scratching your back itch feel so much better than scratching it yourself? Your back consists of thousand of nerves, but where your stomach, arms, legs etc. gets a lot of touch, thus stimulating the nerve points, your back doesn't, ther...
The .com bubble popped and that led into a recession. A devastating terrorist attack certainly did not help. There was a significant recession (drop in the stock market) around 2001, the bursting of the “online” bubble, where huge stock speculation went into companies which had never even produced a dollar profit, but ...
TL;DR: Evolution. Chilis and other spicy peppers have their seeds distributed by animals (like birds) that *are not affected* by the capsicum. Thus their seeds are distributed over large distances, rather than the limited range of land animals.
In the rural area where I live, the well water has a fairly high fluoride content. Because it is a little bit higher than the recommended dose, and certainly more than added fluoride content in city water supplies, our local health unit has recommended that children in our community do not use toothpaste with fluoride,...
The Platform companies not wanting to allow it. They believe they will get less money because people will not buy multiple copies of a game, and they believe that people may move away from their platform entirely. There are also concerns that mouse and keyboard on computers will put those players at an advantage over t...
They didn't instead they worked in large weights, so 2 pounds of element or compound X to 7 pounds of element or compound Y. Knowledge about atoms is relatively recent in chemistry and a lot of early chemists knew what worked, but not how or why.
A lot of the time the generic (store brand) products are made in the same factories as the brand name products. Often the products are even identical or close to identical. But then for others they can have specialised factories. If you look at the number of supermarkets there are all across the country it's easy to ju...
Your kidneys continues to filter blood in your sleep therefore still producing urine. I believe that it is a combination of several factors that makes you pee less while you sleep; - You don't drink any liquid when you sleep, less input therefore less output. - Decreased blood pressure and/or heart rate. Increased bloo...
The article is about a patent that MasterCard filed. Patents are used to protect original and non-obvious ideas -- they give the owner of the patent exclusive rights to the idea for a fixed period of time. This is so you can't come up with a great idea and as soon as you put it in the market, 100 other people put out t...
The slab is refrigerated and kept very cold. This allows you to manipulate the ice cream and mix things into without it melting. Doing this in the store allows you to have very personalized icecreams rather than just having to have pre-mixed choices only. But you could do the same with a steel slab or anything else you...
In a situation when a person actually needs CPR a beating heart takes precedence over anything else even a fractured sternum/ribs. if the ribs puncture your lung and give you a pneumothorax, they can still fix you up later, but if the heart stop beating only for 5 minutes your brain cells will start to become necrotic ...
There are two kinds of nuclear bombs: Atomic bomb and hydrogen bomb. The atomic bomb is an explosion releasing energy of unstable compounds. A hydrogen bomb fuses atoms together and turning them into new atoms. A hydrogen bomb needs an atomic bomb as a detonator. Nuclear bombs are weapons that use energy from nuclear r...
The major contributing factor is your circadian rhythm. This rhythm is basically your natural biological clock. However it does not run exactly on a 24 hr cycle, there are slight deviations naturally and other factors can contribute to altering your biological clock. The next factor to take into account is which stage ...
Vegetarian = eating plants. A world in which all life was either plants or plant-eating would have competition, predators (the plant eaters) and prey (the plants.) If you mean a world of all plants, there would still be competition. If there are 96 nutrients in a given plot of soil and each plant uses 10 nutrients, the...
Well I am a web developer at the opposite end of things to Amazon and Google. If websites were ships those guys are making supertankers and aircraft carriers while I am making kayaks so I can't claim the expertise to actually build things like that but maybe I have enough grasp of the concepts to try a high-level ELI5....
I remember reading an article that suggested that 80% of what doctors currently do will eventually be replaced by a computer. You're definitely right about increasing reductionism/specialization in medicine, and that's not going away. I think the main reason human doctors can't be entirely replaced is due to the import...
Bruising is caused by blood vessels rupturing under the skin. The bruise is basically the blood "seeping" through the tissue. As for speeding up healing, no more than any other internal injury. Your body just has to do its thing. If the pain is bothering you, try ice or anti-inflammatory remedies. If you think it is un...
The two statements are not related. Think of your question this way: "If John has 1000 lbs of rocks and gives me 100 lbs (10%), why are my buckets heavier than his?" The answer, of course, is John carries his rocks in 10 lb buckets and you carry yours in 20 lb buckets. The fact that he had more rocks to start does not ...
Honestly it depends on the person. Some people assume after multiple dates you're exclusive, Some people date multiple people at a time until it is communicated they want to be exclusive. There are a million variations and the best way to know is to communicate, everyone will be different. I think it really depends, ge...
Probably because they are kind of snake-like. From an evolutionary standpoint, it makes sense to be afraid of snakes and snake-like things that can hurt us and it's ingrained in our hindbrain to avoid them.
They had big steel and concrete housings for the cameras and would even pile up dirt in front of them to protect them. The front of the camera would have very thick glass and in some cases periscopes so that the camera would survive if the periscope were destroyed. They also had external film for the cameras so that th...
The American colonies fought for several reasons. 1. They didn't want to pay taxes on goods such as paper and tea. Those taxes were meant to pay off the 7 years war, but the colonists figured that they didn't ask for the war. 2. King George refused to listen to the colonists' problems. They tried to raise issues, but t...
Their speed is mostly for catching insects. They avoid predators using camouflage and hiding rather than speed generally. Who says they don't notice them? If you can move that quickly, you can let a predator approach that much closer before running away, which means you spend less time running and more time doing gecko...
All death -- every last one -- is caused by a lack of oxygen to the brain. Decapitation prevents any oxygenated blood from getting to the brain -- because the brain and the pump (the heart) are no longer connected. We can repair arteries, but there's no possibility of repairing the damage before the brain dies. The vit...
It keeps water from sticking to the inside of the lens. Same thing as soaping up a mirror in the shower.
A little bit of confusion I've seen in this topic. Type 1 diabetes mellitus (DM) is this and only this: Autoimmune destruction of beta cells in the pancreas resulting in the inability to produce adequate insulin. Type 2 DM is basically a catch-all for anything else that results in increased blood glucose levels. There ...
Apparently no one knew for the longest time exactly what it did in the brain, but literally last month a study was released showing that it acts on the seratonin receptors in a rather unique way. So the gist of the article I read was that there are five different types of seratonin receptors, and some drugs act one one...
They send out the CDs, then continue to charge your credit card for years, usually sending you copies of CDs that wouldn't sell otherwise. They didn't give away CDs for a penny. They forced you to purchase many CDs with those highly discounted CDs at a large markup and forced you to join a club where you were essential...
Microbiology PhD student here! A bacteria is a fully complete living organism, just a very small one composed of a single cell (and a smaller, simpler cell than those in your body). It does everything you would expect a living organism to do - it senses it's environment, often moves towards food and away from harmful c...
Fractals can be created with a couple of rules and lots of repetition. It'd be more surprising if fractals didn't occur in nature. Sometimes fractals are energy efficient. I also defer to someone more knowledgeable on this topic.
People are selfish and concerned over being first (even it the difference in time is literally a second or two).
Wind sheer, humidity, temperature, atmospheric pressures, storm systems near by, pollution levels, convection, the jet stream, and altitude. Amount other things. Its why no two clouds seem to ever be identical.
The bubbles contain water vapour and steam. A speck of water heated to that state expands 1700 times, easily making a bubble from 'nothing'. Edit 1700 not 3200, thanks /u/rawwwse Those bubbles aren't air. They are water vapor. The water at the bottom of the pot heats up, transitions to vapor, and then bubbles to the to...
When you're squeezing or biting down or something, your brain is focusing on that instead of the pain.
Just a guess (apologies if that's discouraged here) but I would assume the fact that they're starchier instead of sugary makes them more difficult for bacteria and mold to get into. They're made up of carbohydrates that are more "complex" and so take longer to be broken down.
You're describing the tip of the tongue phenomenon. When we think of a word or thing, we have many cognitions: a visual memory of it, how the word looks when written, the sound it is in your language. When we know something starts with something but can't finish it, we're tapping into a less developed sense of sound an...
It's impossible to say what the cause is in your house specifically, but there's a few things that could be going on here. Note that it's likely that the same creaking sounds are being made during the daytime, too, but there's more going on and more other noises - at night, it's quieter, so you're more likely to hear a...
It's like someone is giving you a box with a code lock and you can put something inside and he will deliver it wherever you want. But still.. He knows the code.
They are more active when it's cooler outside, there's also less noise pollution at night, so even making the same amount of noise day and night, there's less background noise like cars/music/whatever to cover up the cricket sound. Their goal is to attract a mate without being eaten. That's easier to do when it's dark ...
Simply because lying takes effort. They could also be too tired to think of the consequences of telling the truth, or they could have forgotten that they were supposed to lie in this situation. The point being, lying takes serious thought for most people, and being tired reduces a person's ability to think clearly and ...
Pleasure, in this case, from food, is released because you body craves fatty and sugary goods because they give the most energy. You'feel' good when you taste something sugary, and your body rewards you with dopamine after swallowing.
Much of animals' means of identification is through smells/pheromones, which clearly don't transmit over video.
There are times when software gets confused and lost. When it is lost it doesn't know how to get back to home, and home the only place it knows how to "be an mp3 player". Pressing the reset button is like having a GPS tracker on someone who's lost - when you press it, you swoop in, pick the software up and plunk it bac...
Put simply, the left breast is usually bigger because the heart is on the left side of the chest. That's really all it is.
Women *do* go bald. It's just different. Men usually lose hair starting at the crown and moving forward, or at the hairline and moving back. Women usually lose hair in little wisps that pretty much just thin out the hair all over. balding is mostly an hormonal issue. Free testosterone accumulate on the base of hair fol...
The general argument is that regulations like this make it more difficult for someone to open or run a new business or plant, so they are less likely to build that. Those new establishments would have employed people, so by discouraging people from starting these establishments, they are in essence preventing jobs from...
The metal inside is rounded, which helps prevent the charge from finding a way to arc out. Metal in microwaves builds up electric charges that shoot out at the edges. Things like aluminum foil has a lot of edges and corners. Truth be told, if you ding or clip any of those metal racks they will spark and cause a bad day
3 billions years ago, the earth was basically one big chemicals mixing pot, and it spit out all sorts of things. Now, maybe some of the chemicals that formed were really hard, and maybe some could fly, or maybe some could sing. It doesn't matter. The point is, out of all of those chemicals, there was this one such chem...
My college English teacher explained it like this: In middle-english you would talk about shoes owned by Paul by saying 'Paules shoen' In modern English you would drop the e after Paul for an apostrophe and replace the n at the end of shoe with an s: 'Paul's shoes.'
Old people have experience to draw on and tend to be more cautious as they have more to protect. As a result they know many ways things can go wrong as they have seen it happen before. I would counter that people don't get more cynical as they get old, they get less naive. The hopes and dreams of youth get shot down ov...
octane is an additive that makes gasoline less combustable. engines that have very high compression ratio (the ratio of cylinder volume at the bottom of the stroke vs the top of the stroke) can make the gasoline detonate before the piston gets to the top of the stroke. This is bad, commonly called "knocking", this mean...
They typically don't survive. If an animal gets injured, it's game over. This is very evident in predatory animals. Lions and such will careful stake out what they want to get involved with in order to lessen the chance of being injured. Lions and other big cats also typically go for a killing blow to the prey as quick...
If you're going to ask about a current Reddit post, [it's helpful to include a link to it in the question]( URL_0 ). Split screen video games are where you have multiple players, each with their own view on half the screen. Think playing Golden Eye/Halo on a single system. One of the problems you run into here is that ...
Nerves work via electric potentials. These are shifted by ion concentrations. Some liquids affect these ion concentration gradients. If something is strongly acidic, basic, or salty, it will activate the pain neurons that are exposed in a cut.
Part of it is because when a company raises money, they want to have a higher value each time they raise money as this signals that the company is growing.This helps existing investors build up value by investing early and with continuing investment. Each time this company runs out of money, they have to raise more to ...
Bacteriophages are basically just little viruses that infect bacteria. They land on a bacterium and inject their genetic material into it. The bacteria notices the genes and replicates them to make more viruses. When it has made a certain amount of viruses it will explode and release them into its environment.
Small bubbles can block capillaries in vital organs, most urgently the brain, causing anything from pain and inflammation to neurological damage and paralysis. A small bubble impedes blood flow the same way a solid obstruction would — the bubble's surface tension relative to its size is too great for the force of blood...
For those that do feel tired after crying, it's because crying is cathartic. Crying is caused by many things, but I assume you mean sad crying. Usually crying only happens after you build up emotions and try to hold them back. Releasing the dam leaves you mentally exhausted as you just give in to the pain.
It's a part of HTTP, the protocol that defines how webpages are transferred, not HTML, the language in which they are written. So in HTTP, there is a field in the request called "method" which can be GET, POST, or a few others. GET is for reading data, and cannot have a request body, i.e. the request contains only the ...
Microwaves work by agitating the molecules in the food (and apparently soap) that you put inside them. Temperature is essentially a measure of the random kinetic energy in a material, so when the molecules are agitated and caused to vibrate more the temperature increases. Water is very susceptible to microwaves, so usu...
I think I saw a video that explained what being autistic was like. It seems as though over stimulus is really hard for someone with autism to deal with which may result in sort of a crash. Normally your brain filters out the less important information. Like if you're computer was at the limit and just stopped processin...
Evolutionary psychology perspective: social comparison helps us keep track of vital social information related to our own fitness, indirectly. 1) It helps us navigate our social world by paying attention to status hierarchies. Don't mess with high status people because that can get you ostracized in the group. Befriend...
Chocolate has oils in it. The oils would leach out if the packet were pure paper, as well as getting moldy from moisture seeping through. The oils would also react to plastic. The foil also keeps light out better than plastic or paper. Milk proteins react to light over time. It's why milk for schools is in cardboard ca...
Really the only issue is if/when your flights get delayed/cancelled, the airlines won't help you because the tickets were booked separately.
because of air flow. when you pour out of a bottle, you get that 'glug glug glug' thing happen, where a bunch of water comes out, then there's a short break before the next bunch. this is because as the water blocks the lid area of the bottle, the bottle becomes airtight, and the rest of the water cannot flow evenly. N...
We're all familiar with taxes that tax your income. But there's another class of tax that taxes your expenditure - it's called a consumption tax. A goods and services tax is a type of consumption tax. A very simple type of consumption tax is the sales tax that is added on to the price at the checkout. But, what if, ins...
Humans have a biological imperative to seek fats and sugars. Those are really good at nourishing us and we can turn them into super useful fat supplies. They also were fairly rare way back when. So when we have access to them our instinct is to "stock up" on all of this really choice food, because who knows when it wil...
