Ten and Eleven got along better than any other pairing we've seen, except for their brief argument over Trenzalore; they behaved like similarly-aged siblings, despite having several hundred years (possibly) between them."

},
{
"from": "gpt",
"value": "Table salt is composed of two ions, Sodium (Na+) and Chloride (Cl-).\n\nSodium is easily absorbed by the body through rapid uptake, and it also tends to pull water along with it, by action of osmosis. The body uses Na+ for exciting cells, and also to regulate blood pressure by adjusting how much water is present in the body.\n\nThe easiest way for water to move around is with Na+, because it's the most abundant ion in the body. Eating too much salt will increase the amount of Na+ in your body, and that also increases the water absorption, which enters your blood and increases the circulating fluid. This increase in fluid occupies more space, which exerts pressure on the sides of your blood vessel, translating to an increase in blood pressure.\n\nYour kidneys will eventually get rid of the extra sodium, but sometimes, for reasons not very clear, the body decides to keep retaining sodium instead, which leads to high blood pressure. Hence why you're advised to limit salt intake if you're suffering from blood pressure problems."

The the reason that you don't see Sith with more color variations is because they use a mass produced/farmed crystal in their light-saber construction. This allows for utility and uniformity. Sith do not need to \"personalize\" their tools the way some Jedi do. A lightsaber is just a tool to a Sith.\n\nJedi more often choose crystals for their sabers that have some personal meaning. It could be tied to their Knighthood Trials, perhaps they found it on a mission, or perhaps the force led them to it. Each Jedi's Lightsaber is a very personal and customized thing. It is an extension of that person."

If smoke particles enter the detector, they reduce the amount of light that reaches the end of the light barrier. \n\nThe smoke from your burnt sandwich contains alot of soot, which has lots of big molecules.

This is the natural frequency of the ruler when it is that length of the table and thus produces a certain sound. \n\nNow certain materials also will have a natural frequency such as wooden or metal tables and that's why they make different sounds.

On a power/volume basis, it's a lot less than your body emits (about 100 W) and around the same as a compost pile.\"\n\nBasically the only reason the Sun yields so much energy is that it is so staggeringly large.\n\nSo, that being said, what is the use in creating a reactor that - albeit will generate a net positive power - will only output such a piddling small amount?\n\nI feel we are wasting millions (likely billions by now) on this.

},
{
"from": "gpt",
"value": "> So, that being said, what is the use in creating a reactor that - albeit will generate a net positive power - will only output such a piddling small amount?\n\nThe fusion output of the sun per given volume doesn't really apply to how it would be performed in a reactor as our designs aren't reliant on what will naturally occur. Consider the difference between a fission bomb and a fusion bomb, the fusion bomb has a far greater output. A practical reactor will be generating far more energy per cubic meter than the Sun does.\n\nWhile fission of uranium releases about 17 times the energy of deuterium and tritium fusion, the key difference is the availability of the fuel. There is enough deuterium in a gallon of sea water to produce an equivalent energy output of about 300 gallons of gasoline. Instead of refining trace isotopes of an already rare mineral into fuel we can just essentially dump water into such a reactor and create huge amounts of energy; that we need 17 times more water than uranium isn't really a problem.\n\nEdit: Consider that U-235 has a natural abundance of 0.72% and there is about 40 trillion tons of uranium on Earth. That means there is conceptually about 288 billion tons of U-235 on Earth.\n\nOn the other hand deuterium has a natural abundance of about 0.015% and there is about 1.36 million trillion tons of water on Earth. That means there is conceptually 204 trillion tons of deuterium on Earth.\n\nThis means fusion fuel is approximately 708.3 times more commonly available than fission fuel. Oh, and the waste products are far less hazardous."

Their opponent disarms them somehow, or stealthily acquires use of the weapon or tech while the hero is distracted. Of course, sometimes like with James Bond (his Casino Royale biometric signature lockable pistol) or Thor (anyone who is worthy) you'll have the powerful object rendered inert when out of the owner's possession. \n\nBut far too often like with Syndrome and his Omnidroid remote (The Incredibles) or Tony Stark and his Iron Man suits (MCU) you'll have the opposing side taking control of that key *thing* that gives the other person power, and using it against them.

I get that it's more R&D, resources and time required to get the Prometheans from Halo kitted out with Promethean only gear, but surely it's worth it to prevent any random evolved ape from the other side of the Galaxy from salvaging your weaponry when theirs is depleted far from an allied ammo cache. The Dark Lord Sauron couldn't have crafted the One Ring of Power to make the wearer emit a traceable signal to the forces of darkness whilst also paralysing the individual? \n\nThere's always going to be ways around safeguards, but it seems seasoned combatants and \"intelligent\" super-geniuses lack some common sense in the \"let's make sure only I can use this\" department."

We have diverted rivers, built dams, spread radioactive isotopes around the soil layers of the planet - we create a new-endless stream of junk that we collect and bury into massive dumps which will leave unmistakable evidence behind.\n\nUntil the planet is obliterated, strong evidence humans were here will be present to anyone that looks hard."

},

"from": "gpt",
"value": "General anaesthesia has five components, required in various combinations.\n\n1. The patient should be unconscious - hypnosis. This is usually achieved by inducing anaesthesia using an intravenous induction agent such as propofol and maintaining anaesthesia during the procedure using an infusion of propofol or an inhalational agent such as isoflurane or sevoflurane.\n\n2. The patient should not recall what happened during the surgery - amnesia. This is usually achieved by using benzodiazepines such as midazolam.\n\n3. The patient should not suffer pain - analgesia. Intraoperatively this is achieved by giving opioids such as morphine, meperidine, fentanyl, or remifentanil, or by administering a neural block using a local anaesthetic such as lidocaine, bupivacaine, or ropivacaine.\n\n4. Unnecessary or exaggerated autonomic reflexes should be suppressed to prevent harm to the patient. There are multiple ways of doing this based own at reflexes you are targeting.\n\n5. Sometimes the patients need to be paralysed with neuromuscular blocking drugs. This usually the case when a body cavity needs to be opened or when absolute immobility is required. When we do this, we need to take over the patient's respiration too.\n\nMultiple effects needed, multiple pathways. If on the other hand you are looking to find how any anaesthetic acts on the central nervous system, go to Pubmed and search for \"molecular mechanisms of general anaesthesia\"."

Now suppose this guard arrests an intruder with brown hair and a ponytail. They are now on much higher alert than before, so much higher that they start arresting anyone with brown hair, or anyone with a ponytail, even if they are innocent citizens. This is how an infection in your body can cause autoimmune disorders. \n\nThe T-cells in your body are sensitive to particular antigens but are also mildly sensitive to many other antigens, sometimes even self-antigens i.e. your body's own cells. What can happen is that during an infection like chickenpox, the T cell that is specific to a chickenpox antigen will be activated making it much more sensitive overall. It can then react to self-antigens that it was only mildly sensitive to before and begin attacking the body's own cells."

This compartment (called the crop or honey stomach) is designed to allow the bee nectar storage while it is foraging. When the forager bee returns to the hive she passes the nectar to a receiver bee who puts it in a wax comb cell for ripening. Nectar has a high moisture content, perhaps 40+%, but the bees want to store the honey for future consumption. They regulate the humidity in the hive via wing flapping over fresh stored nectar and move air in and out from the entrances. Once the honey is at 17/18% moisture content it is ready for capping. The bees cap the cell with wax and that honey will stay in storage until they need it.\n\nIf the season goes well, the colony may collect for example, twice the amount of honey they will need for winter.

They were opposed to the church and king, socially progressive and were viewed by many as a threat to the fabric of European identity.\n\nIn essence, an internal Spanish struggle became an ideological proxy war in a very liminal period in history. The old order had just led to WWI and the Great Depression, and people were trying to decide in what direction to chart their future. Communists and Socialists flocked to the Republican cause, Fascists and Nazis to the Nationalists.\n\nIt became a test by which three new powers, Stalin's USSR, Hitler's Germany and Mussolini's Italy, could test both their newly developed military hardware but also their global influence."

Humans were propelled forward technologically through the raiding of the technology on the Vulcan scout, but other species would be less willing to share technology, driving the \"Terrans\" to a hostile campaign of enslavement. \n\nThe result is that in the 100 years or so between the different first contact and the species you've seen, at least an entire generation of many species you are familiar with was born and died under the yolk of slavery. Their cultures destroyed and their outlooks tainted by being completely dominated by the Terran Empire, many species may look \"opposite\" to you. But the incident that changed them was the interaction with the humans over an extended period. Peaceful species who survived the first attacks became warlike over a generation, as it was the only way to survive. Species known for their aggression were either destroyed in the first attacks and forced into captivity (and thus the next generation would be one born away from the warlike influence of their previous culture), or learned to fight differently as a way of surviving. \n\nSo, in conclusion, it isn't that some event changed every species, turning some \"evil\" and some \"nice\", it's that the massive spread of the very violent Terrans forced a number of changes over the years. In 100 years of conquest, a lot can happen, and the cultures that one would associate with species in our \"prime\" timeline became warped or outright destroyed."

A cat would see a vertical slit shape, a goat would see a rectangle, and so on.\n\nWhy is this useful?\n\nLet's take the cat for example. The vertical bokeh created by their pupils means they see things with a vertical blur to them and the horizontal remains sharp. If their prey tends to flee sideways, this means they can let more light in their eyes while still seeing exactly where their prey is going.\n\nThere are similar evolutionary reasons for the shapes other irises take."

I don't think those who are uneducated about politics and the candidates that they're choosing between should be allowed to vote. It doesn't seem to have any benefits if a person votes based on factors like what their friends/family think about the candidates or something they heard on Reddit.\n\nI started to think about this when my friend told me I should register to vote. I should note that I know almost nothing about the current presidential candidates (or any election for that matter) and never had any interest in politics. I know I should be more educated about whos running the country Im living in but as of right now Im not too interested. My friend convinced me to register and I decided I was going to vote for Bernie because I heard he supports weed legalization and I heard some people say he was a good choice. Then I realized, why should I be allowed to vote if I have no idea about anything in this election? It feels like my vote, based off of a couple minutes of research and what I've heard online, would not be beneficial towards the selection of an appropriate leader for our country. \n\nI understand most people who don't know much about politics would choose not to vote anyways, but what about those who are doing something similar to what I was doing, making judgements off of what other people say, which could be biased and lacking important information.\n\nI don't know how a system could be implemented in order to \"test\" individuals for political competency but I do feel that some people just shouldn't be allowed to vote, myself included.\n\nThank you for reading, please change my view Reddit.\n\nEdit: \nWow that was fast, read through 5 replies so far and I have changed my view. Thanks for the great replies everyone."

So there was great demand for internet-cafes where you could access this high-speed resource without necessarily needing to pay high prices for your own computer.\n\nIn a heartbeat, internet-cafe culture was EVERYWHERE. Per-capita, the US doesn't hold a candle to South Korean connectivity. If you had a cafe near you, you could get online, and given that such a high proportion of the country lives in high-density urban areas, this basically permeated the entire country.\n\nNote that at this time, in the US, you'd be lucky to even have a 56.6k dial-up modem, let alone broadband.\n\n1998 rolls around, and Starcraft gets released. Korean school children eat it up. It becomes the most popular activity at internet cafes (which are ubiquitous). An entire generation grows up on Starcraft. And overnight, it becomes the national pastime.\n\nEntire channels pop up to broadcast Starcraft. Sponsorships, teams etc. arise. Korea becomes the birthplace of eSports, and the rest is history."

"value": "Photosynthesis = H20 + CO2 + Light (particularly UV/V/B light) made into O2 (oxygen gas) + C6H12O6 (Sugar).... Let's keep that simplification in mind for now.\n\nWhen we think about plants making O2 to offset the CO2 production, you run into two key limitations: water and rate of photosynthesis. When there is no water (particularly clean, harmless water), it prevents the process of photosynthesis from occurring. That is why a drought can be devastating in that regard. This usually isn't an issue as rain forests contribute much of the plant-based global-O2 generation and these environments are not insanely water deprived (but global warming and deforesting have still affected this cycle in some regards).\n\nThe biggest issue is rate of photosynthesis. Just because more CO2 is present, that does not mean the plant will engage in photosynthesis much quicker. Think of it like this: let's say your car tops out at 100mph. Does adding more gas in your tank make your car faster? The answer - no. Your car (plant) is still limited by its internals (plant chlorophylls) regardless of how much gas (CO2) is in the tank (atmosphere).\n\nAlso, the Ocean makes about 70% of oxygen. Phytoplankton and the sorts, and they are also in danger due to the dropping quality of ocean water in some regions.\n\nEDIT: Phone auto corrected \"in danger\" to \"endangered.\""

I tried searching \"polytheism\" on the SEP and IEP but the closest I got was the article on Hindu Philosophy on IEP.

That affection for polytheism became very prominent within the Romantic Movement and, through it, passed into later Western culture where it's remained a strong theme.\n\nThere are writers around associated with Neo-Paganism who advocate polytheism (Timothy Jay Alexander is the latest to do so with some philosophical understanding) but few work in academia and none are part of the \"canon\" which is heavily orientated towards Aristotelian modes of thought and exclude nous and other kinds of apprehension. *Esotericism and the Academy: Rejected Knowledge in Western Culture* by Wouter Hanegraaff might be worth reading in relation to some of these ideas."
