Knowledge is something that can always be improved. At the same time, it's also a thing that no matter how much effort you put in, you'll have some blind spots because it's impossible to know absolutely everything, isn't it? There are things that we are doomed to never learn about. But today's list isn't about them. Instead, it's about the things many people don't know but can learn about. And when is a better time to start than now?

This is definitely false. If you move out o the walkway, you will likely be in the road, where there is a very good chance that you could be deleted.

Obviously no one is suggesting you move your conversation into street traffic. Most sidewalks have 2 sides: the dangerous side such as the road or a cliff or a river and the safe side such as a building or a park. Just step out of people's way for the duration of your conversation. Safely.

    According to various definitions I'd rate this as 'mostly true. True in that graveyard is more commonly associated with a church, but untrue in that both words are technically correct whether or not a church grounds is involved. So not a great hill for the grammar nazis to die on (pun intended). --- "The word cemetery (from Greek κοιμητήριον 'sleeping place') implies that the land is specifically designated as a burial ground and originally applied to the Roman catacombs. The term graveyard is often used interchangeably with cemetery, but a graveyard primarily refers to a burial ground within a churchyard."

    Probably many of us have heard the saying that “knowledge is power” at least once in our lifetime. This phrase comes from the Latin aphorism "scientia potentia est" (the words can be placed slightly differently, but it doesn’t change the meaning). Commonly, it’s attributed to Sir Francis Bacon, former Lord High Chancellor of Great Britain, as the expression "ipsa scientia potestas est" ('knowledge itself is power') occurred in his book “Meditationes Sacrae” (1597). 

    ADVERTISEMENT

    As you can see, Francis Bacon didn’t use the exact aphorism that’s assigned to the “knowledge is power” saying. The first time this exact Latin phrase was written was in the 1668 version of “Leviathan” by Thomas Hobbes, an ex-secretary to F. Bacon.

    Nah. More like an overlapping Venn diagram. Biology includes some chemistry but not all of the field of biology is chemistry. Behavior and distribution are just two of the parts of biology that are not chemistry.

    Many people (including my younger self) are also mistaken about what is inside the breathing apparatus. No, it's not oxygen, because 100% oxygen would kill us. It's just compressed air.

    Bob Brooce

    1 year ago Created by potrace 1.15, written by Peter Selinger 2001-2017

    Yes and no. A lot of people are mistaken about the standard (insofar as there is one) gas for SCUBA, but many gas mixtures besides regular air are used. Recreational divers often use Enriched Air Nitrox (commonly referred to as just "nitrox" though nitrox is really any mixture of nitrogen and oxygen).Enriched Air Nitrox is air that has a higher than normal percentage of O2 to reduce the uptake of nitrogen during the dive, which extends he allowable duration of the dive. Technical divers often use "trimix" with is O2, N2 and helium. Decompression divers often use pure O2 or high % O2 mixes to speed the offgassing of N2. O2 is toxic at high partial pressures, s the amount of O2 in the mix determines the maximum depth at which it can be used. Pure O2 is used for the final (and long) stage of decompression at 20'.

    Thank you Jacques Cousteau and others for the invention/conception. I learned about "Scuba" from the 1950s TV show, Sea Hunt, and the early 1960s TV show, Assignment Underwater. Watching Lloyd Bridges underwater made this Boomer as a kid to fashion his own air tanks out of rolled up cardboard strapped to my back with my suspenders and my mom's vacuum cleaner hose. My buddies knew exactly where I was coming from, but all the adults thought I was just a weird kid.

    Yet, even though knowledge is power, everyone carries different levels of it. And this leads to the phenomenon of the “curse of knowledge” or “the curse of expertise.” It’s a cognitive bias where people incorrectly assume that everyone knows as much as they do on a certain topic. This makes it hard for them to imagine what it’s like to not have that knowledge.  

    One of the most interesting experiments done about this curse, which also quite easily explains the phenomenon, was conducted in 1990 by a Stanford University psychology graduate student Elizabeth Newton. She created a game, where people were assigned roles of “tapper” and “listener.” Tappers had to tap out the rhythm of a well-known song on a table, while the listeners had to guess the song. 

    Out of 120 songs tapped out during the experiment, only 3 were guessed correctly. Yes, only 3! Apparently, when a tapper taps, they hear the tune in their mind along with the taps, while the listener only hears the uncoordinated tapping sounds. And due to the curse, the tappers couldn’t see why it was so hard for listeners to understand the tune.

    I'm so tired of seeing this. It is not true. TL:DR - bad science based on filming 32 animals where the actual number is 0 seconds to 48 seconds. One study (Yang, et al 2014) looked at 32 animals at a zoo and discovered they pissed 21 seconds +/- 13 seconds. One standard deviation means that 67% (21 of 32) pissed between 8 and 35 seconds. 95% pissed between 0 and 48 seconds. You wonder how 0 is possible. The study includes a graph showing it takes a rat .16 seconds.

    I thought it couldn't be true, because to the best of my knowledge rodents don't have bladders, they just expel urine as and when it's created

    Seems to be based on the much-hyped Yang etc al (2014), which says "all mammals above 3 kg in weight empty their bladders over nearly constant duration of 21 ± 13 s." Yes, that's remarkable consistency given the biological variance; still, plus or minus 13s per species (n = 32) plus the weight constraint suggest that it's probably not reliable. My own research (n = 1) suggests the variation in a single species can vary from a few seconds to at least several minutes depending on age, position, type and quantity or liquid consumed and the proximity of other species members.

    Said paper explicitly said small mammals such as mice and rats don't pee this way, incidentally, but in frequent urination of single drops.

    According to the authors, the main reason was that urination time is a very easy thing to observe and yet can be highly useful for diagnosing urological disorders "as well as inspiring the design of scalable hydrodynamic systems based on those in nature." Regarding the latter, "Engineers may apply this result to design a system of pipes and reservoirs for which the drainage time does not depend on system size. This concept of a scalable hydrodynamic system may be used in the design of portable reservoirs, such as water towers, water backpacks, and storage tanks." Funding was from an early career physics grant for the physical modelling and an undergraduate research award for the experiments.

    Upper case - taken from the upper case of letters. Lower case - taken from the lower case of letters. Both from the printing world, the lower case letters were used far more frequently so they were stored in the case closer to the typesetter who picked the individual letters to make up the lines that were then stacked into forms for printing.

    These terms are related to metal typesetting. With the rise of IT, font has been used interchangeably (and in German font is used for typeface - highlighting for font [typography-terms for use with software publishing]). In typography itself, font is a complete character set in a particular point size, in a particular typeface. I hope it's not too confusing, but publishing changed completely while the art, rules and terms of "setting text" are roughly the same.

    While I'm not disputing the fact, in my experience font was commonly used to refer to the typeface in casual use when I was involved in some smaller scale publishing. I think it's a bit like when someone tries to tell you Kleenex is a specific brand and you should say tissue. It's true, but a lot of folks are going to say Kleenex (or same for Q-tips) anyway.

    The OED evolves, slowly, but it does evolve. When I was in HS (in the early 70's) , I was in printing using cold type. The "font" was the package of individual letters, the "type", that was then distributed into the "job cases" for hand setting the cold type into a composing stick. The typeface was the style of the type.

    That's because typewriters haven't been used in forever, and typeset (cast) hasn't been used in longer than that. Font covers the specific set and the adjacent bells and whistles now, mostly universally.

    Technically, False. But also true. The Amazon river proper does not have any bridges. However, there are many small bridges crossing the distributaries, which are still part of the same river (as they leave and re-join the river). I know this for a fact because I have crossed them, just outside of Iquitos, Peru.

    The two biggest reasons are 1)most of the Amazon basin doesn't have roads to connect that would need a bridge and 2)the river's width varies greatly from season to season. It can go from 4-5km at its widest to 50km in weeks during the wet season. The Amazon delta where it dumps into the ocean is 320km wide and a 100 km deep and it constantly changes.

    Another factor - both sizes of pizza probably have roughly the same amount of 'dead zone' out by the crust edge so the sauce and toppings don't fall off in the oven. So that bigger pizza not only has more total area, it probably also has a greater percentage of it with toppings. But I'm not going to try to bother with the math to verify that.

    You only need to do the math if you want to quantify it precisely. The crust is normally the same width, so it increases in direct proportion to the radius, while the saucy part of the pizza increases as the square of the radius.

    If you want to compare relative sizes (area), just square the diamteter. A 10" pie gives 100, and a 14" pie gives you 196. So, quite quickly you know that a 14" is about twice (196%) of a 10". 18^2 = 324, 12^2 = 144, double that 288, which is less than 324.

    Same with my cousin--she was trampled by her horse and the doctors told her she probably wouldn't walk again, especially with all the nerve damage. I think she forced herself to walk again out of pure spite.

    I've got cauda equina. I've a lot of nerve damage. I'm numb from my buttock to my toes on one leg and I'm numb in my undercarriage. The pain is constant and my nerve damage is permanent.

    I seem to recall another BP article that said it was the lack of signal that caused the pain. I'm a bit fuzzy on it but the gist as I recall is that your brain is used to receiving a constant signal from any given nerve and having that signal disconnected is perceived as pain. It seems counter intuitive to me so the answer is probably deeper than that. It was part of an article about why people with amputations feel 'pain' in their hand / foot / whatever that is no longer part of their body.

    Basically, pain is strange (heck there’s even a book about pain called that). Chronic pain is classed as nociceptive pain - there is no structural damage to nerves or tissue/bone, but the CNS has become sensitised and so produces pain before there is any need to protect by pain.

    CRPS is fascinating (although not if you have to live with it) because of the physiological changes that take place in the affected area/limb. Hair growth changes and nail growth changes, the limb is a different colour/temperature. There’s been recent research investigating the role of immunoglobulins in causing it (injected into mice who developed symptoms, they’ve also demonstrated that with fibromyalgia too)

Once ignited, these subterranean fires are almost impossible to put out. Slowly but intensely, they travel through the coal seam, a layer of coal that naturally occurs beneath Earth's surface.“ https://www.sciencealert.com/this-mysterious-fire-in-australia-has-been-burning-non-stop-for-at-least-6-000-years

    "Somehow" - they were using a former pit-mine as the town trash dump. They thought they'd sealed it completely before converting it but they hadn't. It didn't matter until one Memorial Day in the 60s when they mayor decided the dump was an eye sore for all their planned celebrations so he instructed crews to burn it. They set it on fire and turned out they hadn't sealed it well enough, the fire had gotten into a mine shaft under the pit and started to spread. From there it was very largest the fault of the state govt failing to invest the money needed to do the job properly of finding out where the fire was located and putting it out.

    Someone set a pile of trash on fire too close to a crack leading down to the coal seam they were mining. It spread down into the mine. They didn't take it seriously at first, and didn't take action quick enough. Due to the properties of the coal, it's nearly impossible to put the fire out at the moment, so it will be expected to burn for another few hundred years or so....

    Not sure whether the bow wow theory holds up. There is a theory that different sounds are created and learned as an infant gains more and more control over their mouth, tongue and vocal cords. The easiest sound to make is a "ma" sound which is why the word for mother is practically every language is an "M" word. Similarly, the "da" (or "pa") sound is the next one controlled therefore fathers are mostly "D" or "P" words. Seems more likely that we make sounds naturally and they just organically evolved as our vocal systems got more complex.

    33 Facts That Might Teach Quite A Lot Of People Something New Your eyes have a separate immune system from the rest of your body. If they get damaged in such a way that it affects anything other than your eyes, your regular immune system can attack the damage and will not recognize them, meaning your own body can permanently blind you. What's worse, your body cannot tell the difference between either eye. If one of them gets infected or damaged, your immune system can attack your healthy eye and take away your sight entirely.

    Ocular immune privilege, still not fully or mostly understood, we do know it performs this task quite well. This also makes eyes a great way to research therapies, because the immune response is localized, sometimes immediate and easy to track. The eyes aren't the only part that have this, though they do have a more extensive "system" of their own (using local mechanisms and global, meaning, outside of their system). A pregnant uterus, the testis and some areas of the brain also have this sort of function to better protect themselves and the rest of your body too. If you have an eye that has never functioned it's possible that eye and it's little quirky system can misfire and determine your functional eye (or even another part of you) is an enemy that must be destroyed, immediately, should you get an infection or injury. Makes for some interesting research, but not at all fun for me, lol.

    So. Very. True. I had a scratched cornea from work one time - did not know it at the moment, but flooding my eye with water did *not* solve the issue. Boss refused to let me to seek medical treatment, so since I worked in a Mall I went to the optometrist on my lunch break. He grimaced, and ooohhh'd and awwww'd, and said I had to immediately go see his ophthalmologist buddy. I told him my boss wouldn't let me go, maybe I could call in sick tomorrow and go see him. Nope, damage would already be done. I was a dumb 21yr old and should have left and filed worker's comp, but instead, I couldn't take it anymore at one point, yelled at my boss for being an overbearing bsturd, went home and put on my sleep mask so I'd stop blinking constantly and slept as long as I could. Luckily, it didn't get infected, or I'd have been effed.

    I live on a very small island, and there has been significant investment into ensuring all of the children in school receive first aid training. We also have defibrillators in public spaces. You phone the number on the box, get the code to open the machine, and the operator talks you through using the machine. Whilst this is happening, an ambulance is despatched. The distance/time to get to hospital is much smaller than in other countries. Because of all of these factors, when a person starts CPR, the patient has a 300% - 1000% higher rate of survival than in the neighbouring countries.

    In voluntary firefighter training we were also trained in CPR by the city's first responders, and were told: If after a heart attack, everything is handled well (defibrillator immediately, ambulance within 15 minutes and immediate hospital care) the survival rate is only 50%... So if you ever need to apply your CPR-knowledge, do what you can, but don't feel guilty if the patient doesn't make it.

    Depends on the circumstances. If arrest occurs under anaesthesia, outcomes can be generally good depending upon patient age. Since oxygen and IV access are already present, everything happens much faster.

    This is correct, good recovery after CPR is single digits. They count it as recovery if you don't die during or immediately after. But most people die a bit later. It's not like on TV.

    Last I read, CPR has about a 10% success rate outside of a hospital. In a hospital at the hands of a skilled team, it's closer to 22%. But just because you get the heart beating doesn't mean all is well. It's very easy to arrest again, and it will certainly happen again if the underlying problem isn't dealt with. If the person goes down and CPR isn't started immediately (a lot of times a bystander finds the person down and calls EMS), then there's a good chance the brain will be irreversibly damaged.

    The same thing goes for animals. Please don't feel guilted into checking that "yes' to CPR in the event somethng goes south when you drop off your animal for surgery . The odds are abysmal also, and most folks don't have pet insurance to cover the cost of it, which can quickly become a LOT.

    I read that breathing air into the person’s lungs is no longer recommended and chest compressions are what you need to focus on. Stopping to do mouth-to-mouth interrupts your chest compressions, which are most important.

    Not quite right. People with certain conditions can suffer a form of attack as a result of laughing (such as an asthmatic having an asthma attack, and narcoleptics falling asleep), and smokers can have a phlegmatic attack which can cause blockages in the lungs and airways. The act of laughing forces air from the lungs (including stale air), which is why a good laughing session always includes a large intake of breath. The collapsing of a lung occurs when air gets trapped between the lung and chest wall, which would not occur when laughing. *Unless there was another force/injury, such as a broken rib, which is rare, but possible.

    Lungs can also just spontaneously collapse. Risk factors include being a tall, skinny man, and certain other conditions like vascular EDS. It happens a fair amount in teenage boys for no reason other than existence. It’s very treatable, with some evidence suggesting in mild spontaneous pneumothoraxes, the best course of action is watching and waiting (per NEJM), but chest tubes and even surgery can be used in more severe cases. Reoccurrence is relatively common, but surgery lowers that risk. My dad just had his second in 5 weeks.

I walked around for a couple of days before being convinced to go to hospital emergency room. This was years ago when my asthma was not being controlled well. I was not having an asthma attack that day, but just sitting down writing a letter. I NEVER let my asthma get bad for more than a couple of days now, then a trip to an urgent care center for an x-ray.

    33 Facts That Might Teach Quite A Lot Of People Something New The human body has no means of sensing "wetness", and thus doesn't know what "wetness" is. It can only sense temperature and pressure. Put on a latex glove and submerge your hand in water, and it will feel wet. The movie The Fifth Element is the only movie to reach general audiences, in which the protagonist and antagonist are never made aware of one another, let alone meet on screen. Domestic cats have what's known as a "Non-Fatal Terminal Velocity". Which means that, provided they are of healthy age and weight, you could punt one out of a 747 at cruising altitude and it would hit the earth with no measurable damage. To temporarily reduce, or remove entirely, the symptoms of tinnitus, cover your ears with your palms as hard as you can, and ensure you middle fingers are touching behind your head, then rapidly tap the entire length of your fingers against the base of your skull. You may own your phone, as in the piece of hardware in your hand, but you own exactly none of the things it can do. Remember that when texting, taking pics, posting online, or anything else you do.

    I'm not sure the Fifth Element one is right. I mean the antagonist is approaching from space as some sort of nebulous threat. But they are aware that it's approaching. While they never meet it as such surely that counts as being aware of it? And I'd say Lord of the Rings is the same. Frodo never meets Sauron, he's just a nebulous threat in the background. All the actual interactions are with minions, just like Fifth Element...

    Your immune system has at least 1 cell to combat every single infection that could ever exist. Your T-cells are cells that, when created, go through a sort of training phase in the thymus where they are allowed to change their genetic code at random, in order to be able to battle 1 random very specific disease. During this, the body also kills any T-cells that are accidentally adapted to kill human cells. Then the T-cells are sent to lymph nodes, to be found later by presenting an antigen (a part of a pathogen) to it. Basically you have something for everything in your body, the problem is just finding it, as it takes a good few days for your body to locate the specific one.

    Ok, this isn't exactly correct. The genetics of our immune system are heckin lit, and come with a ton of ways to create antibodies to just about everything infectious we might encounter, but not to everything. There's a region in the genes of antibodies called the hypervariable region that frequently mutate in order to bind to diverse antigens, and do a pretty darn good job at helping the adaptive system to recognize many, many kinds of antigens. However, there are some antigen 'shapes' that your specific antibody genes just can't recognize. Sort of like an immune blind spot. And this is true for everyone. So there are always some antigens that our specific immune systems won't respond to. I mean, it covers most infections, just not 100%. Which is still pretty damn impressive!
