Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they interact.
Quantum physics underlies how atoms work, and so why chemistry and biology work as they do. You, me, and the gatepost – at some level at least, we’re all dancing to the quantum tune.
If you want to explain how electrons move through a computer chip, how photons of light get turned to electrical current in a solar panel or amplify themselves in a laser, or even just how the sun keeps burning, you’ll need to use quantum physics.
The difficulty – and, for physicists, the fun – starts here. To begin with, there’s no single quantum theory. There are quantum mechanics. the basic mathematical framework that underpins it all. which was first developed in the 1920s by Niels Bohr, Werner Heisenberg, Erwin Schrödinger, and others.
It characterizes simple things such as how the position or momentum of a single particle or group of few particles changes over time.
But to understand how things work in the real world, quantum mechanics must be combined with other elements of physics – principally, Albert Einstein’s special theory of relativity, which explains what happens when things move very fast – to create what is known as quantum field theories.
Three different quantum field theories deal with three of the four fundamental forces by which matter interacts: electromagnetism, which explains how atoms hold together; the strong nuclear force, which explains the stability of the nucleus at the heart of the atom, and the weak nuclear force, which explains why some atoms undergo radioactive decay.
Over the past five decades or so these three theories have been brought together in a ramshackle coalition known as the “standard model” of particle physics.
For all the impression that this model is slightly held together with sticky tape, it is the most accurately tested picture of matter’s basic working that’s ever been devised. Its crowning glory came in 2012 with the discovery of the Higgs boson, the particle that gives all other fundamental particles their mass, whose existence was predicted on the basis of quantum field theories as far back as 1964.
Conventional quantum field theories work well in describing the results of experiments at high-energy particle smashers such as CERN’s Large Hadron Collider, where the Higgs was discovered, which probe matter at its smallest scales.
But if you want to understand how things work in many less esoteric situations – how electrons move or don’t move through solid material and so make a material a metal, an insulator, or a semiconductor, for example – things get even more complex.
The billions upon billions of interactions in these crowded environments require the development of “effective field theories” that gloss over some of the gory details.
The difficulty in constructing such theories is why many important questions in solid-state physics remain unresolved – for instance why at low temperatures some materials are superconductors that allow current without electrical resistance, and why we can’t get this trick to work at room temperature.
But beneath all these practical problems lies a huge quantum mystery. At a basic level, quantum physics predicts very strange things about how matter works that are completely at odds with how things seem to work in the real world. Quantum particles can behave like particles, located in a single place, or they can act like waves, distributed all over space or in several places at once.
How they appear seems to depend on how we choose to measure them, and before we measure they seem to have no definite properties at all – leading us to a fundamental conundrum about the nature of basic reality.
This fuzziness leads to apparent paradoxes such as Schrödinger’s cat, in which thanks to an uncertain quantum process a cat is left dead and alive at the same time. But that’s not all. Quantum particles also seem to be able to affect each other instantaneously even when they are far away from each other.
This truly bamboozling phenomenon is known as entanglement, or, in a phrase coined by Einstein (a great critic of quantum theory), “spooky action at a distance”. Such quantum powers are completely foreign to us, yet are the basis of emerging technologies such as ultra-secure quantum cryptography and ultra-powerful quantum computing.
But as to what it all means, no one knows. Some people think we must just accept that quantum physics explains the material world in terms we find impossible to square with our experience in the larger, “classical” world. Others think there must be some better, more intuitive theory out there that we’ve yet to discover.
In all this, there are several elephants in the room. For a start, there’s a fourth fundamental force of nature that so far quantum theory has been unable to explain.
Gravity remains the territory of Einstein’s general theory of relativity, a firmly non-quantum theory that doesn’t even involve particles.
Intensive efforts over decades to bring gravity under the quantum umbrella and so explain all of fundamental physics within one “theory of everything” have come to nothing.
Meanwhile, cosmological measurements indicate that over 95 percent of the universe consists of dark matter and dark energy. stuff for which we currently have no explanation within the standard model, and conundrums such as the extent of the role of quantum physics in the messy workings of life remain unexplained.
The world is at some level quantum but whether quantum physics is the last word about the world remains an open question. Richard Webb
Let me tell you something the doctors never tell anyone.
In our curriculum, we are secretly taught how much radiation, what powers can one get.
10 rad – lightweight.
100 rad – superhuman speed.
1000 rad- superhuman strength.
10000 rad – invisibility.
1000000- radioactive eyes with lasers.
100000000 rad – invincibility.
But these are not tried ever in humans because of side effects.
BULLSHIT. RAD IS NOT EVEN THE SI UNIT OF RADIOACTIVITY.
But what can radiation give us?
Can radiation really give humans mutant powers like in comics? Absolutely not. Radiation can have any of three effects on living things:
1:Nothing
2:Tissue damage.
3:Chromosome damage.
When it comes to mutation, we are only concerned about #3.
When chromosome damage occurs in somatic cells (that is, any cells except eggs and sperm), it also has one of three effects: 1) nothing, or 2) the damage gets repaired, or 3) broken cell metabolism.
The latter amounts to tissue damage, because it screws up the proteins and enzymes the cell is making, or screws up the genes that regulate the cell. The most likely result of this is that the cell dies, and when this happens to a large number of cells all at the same time, we call it radiation sickness.
If you recover, it means all the most severely damaged cells have died, but those that remain have a small chance of going wrong in the future, the biggest effect of which is an elevated lifetime risk of cancer.
All of this is also true when chromosomes are damaged in gametes (sperm and eggs) and again, the most likely result is that the damaged cells will simply die. If they don’t, there is a chance that mutations may affect the development of future generations, but this doesn’t mean what you think it does.
Why? Because contrary to widespread misapprehension, the vast majority of mutations are harmless. Most biological processes are highly immune to variations in the exact form of most proteins and enzymes, and sexual reproduction ensures that we all carry two copies of most of our genes, so even if one copy isn’t up to snuff, the other can generally pinch-hit.
When most people think of mutation, they think of three-headed cows and other monstrous developmental defects, but in fact, most of these are just that—developmental defects. Genetic mutation can sometimes cause such profound and obvious deformities, but for the most part, such gross errors never survive to become embryos.
So you can put aside your fears that nuclear war will give rise to a race of one-eyed, Tripple-teated boogie-men. That cannot happen. What would happen is that cancer and stillbirth rates would rise for the duration of exposure to the radiation, and otherwise, life would go on as before.
So what about superpowers?Sorry, no. First, most of the superpowers shown in thecomics are impossible(flyingwithout wings,laser vision,telekinesis, etc.).Some others are not, but are beyond the reach of mutation.
For example, if you have red hair and green eyes in your family and consider that a superpower (it is, right?) then there is a very small chance that exposure to radiation might toggle a control gene and give you a ginger child that otherwise might not have been. But radiation can’t give your child the snake-haired head of medusa—you don’t have the raw materials for such a change in your genome.
There is one superpower that radiation conveys. By increasing the mutation rate, it increases the variation within living populations, and that gives nature more raw material to select from. This can accelerate evolution, but don’t get too excited. You already have an evolutionary superpower that does this—sexual reproduction.
Sex vastly increases the variation within a population and does it without relying on mutation. Radiation will increase the variation among your kids, but equally among simple life forms which—because they breed by the trillions—are better suited to take advantage.
That is to say, radiation favours simple life, it is a superpower for microbes, including those that prey on us.
Let me tell you a real story:
Have you heard of Hisashi Ouchi?.
Hisashi Ouchi was one of three employees of the Tokaimura nuclear plant to be heavily impacted by the accident on 30 September 1999. Leading up to the 30th of the month the staff at the Tokaimura nuclear plant were in charge of looking after the process of dissolving and mixing enriched uranium oxide with nitric acid to produce uranyl nitrate, a product which the bosses of the nuclear plant wanted to have ready by the 28th.
Due to the tight time constraints, the uranyl nitrate wasn’t prepared properly by the staff with many shortcuts being used to achieve the tight deadline. One of these shortcuts was to handle the highly radioactive produce by hand. During their handling of the radioactive produce while trying to convert it into nuclear fuel (uranyl nitrate is used as nuclear fuel) for transportation the inexperienced three-man crew handling the operation made a mistake.
Tokaimura nuclear plant
During the mixing process, a specific compound had to be added to the mixture, the inexperienced technicians added seven times the recommended amount of the compound to the mixture leading to an uncontrollable chain reaction being started in the solution.
As soon as the Gamma radiation alarms sounded the three technicians knew they made a mistake. All three were exposed to deadly levels of radiation, more specifically Ouchi receiving 17 Sv of radiation due to his proximity to the reaction, Shinohara 10 Sv and Yokokawa 3 Sv due to his placement at a desk several meters away from the accidents. When being exposed to radiation it is said that anything over 10 Sv is deadly, this would prove to be true in this instance.
During the accident, Ouchi was exposed to 17 sieverts of radiation with 8 sieverts being normally considered fatal and 50 millisieverts being the maximum limit of annual dose allowed for Japanese nuclear workers
Ouchi’s exposure to the radiation was so severe that his chromosomes were destroyed and his white blood cell count plummeted to near-zero. Most of his body had severe burns and his internal organs received severe damage.
It was cruel that he was resuscitated on the 59th day when his heart stopped three times within a period of 49 minutes, despite wishing not to be let to suffer.
After being treated for a week, Ouchi managed to say, “I can’t take it anymore… I am not a guinea pig”. However, the doctors kept treating him and taking measures to keep him alive, which only ensured a very slow and very painful death.
After 83 days of struggle, Ouchi died of multiple organ failure on December 21, 1999.
He was the only human being ever in history to be exposed to such an amount of radiation at a time.
It was considered equivalent to the hypocenter of the blast of Hiroshima Nagasaki.
So, yeah, let the superpowers attained by radiations stay in the movies, while we continue to wear a lead jacket while operating an orthopaedic case.
This question originally appeared on Quora. Ask a question, get a great answer.
Intelligent people are motivated through comprehension and recognition, while average people are motivated through effort and security.
Everyone has a burning drive inside of them. For some, they need to learn from others to find it. For others, the drive comes naturally and pushes them to do great things. See what those naturally highly motivated people do differently and what they can teach us.
1. They move on
Highly motivated people don’t dwell on problems. If they mess up on a speech in public, fail a test, or do something embarrassing, they don’t try to push it away. They don’t let their mistakes stop them from achieving their goals. Instead, they look at these mistakes as nothing but simple moments in their life. They accept them, learn from them, and move to the next thing on their to-do list.
“You build on failure. You use it as a stepping stone. Close the door on the past. You don’t try to forget the mistakes, but you don’t dwell on them. You don’t let it have any of your energy, or any of your time, or any of your space.” – Johnny Cash
2. They wake up early
For most people, the morning is the most productive time of the day. While the world sleeps, highly motivated people are getting things done. Distractions seem to disappear and great ideas will come fast in the early morning.
“Early to bed and early to rise, makes a man healthy, wealthy and wise.” – Benjamin Franklin
3. They read…a lot
When Bill Gates and Warren Buffet were asked if they could have one superpower they answered the same thing: to be able to read faster. Highly motivated people are always learning. Reading allows one to take in the knowledge of some of the smartest people who have ever lived. Highly motivated people don’t spend much time watching reality TV – they do, however, spend their time reading. Need some books to read? Get started with this reading Here.
4. They set goals
Highly motivated people are always working for something. They know what they want, and they search for ways to achieve it. Lifehack is filled with great articles on setting goals. Check out this one and start working for something.
5. They plan
Highly intelligent motivated people don’t leave things up to chance. Planning allows people to get things done faster and better. Highly motivated people know this, and they make use of it. Start waking up and planning all the things you have to do for the day. You’ll be amazed at how much more productive you are.
6. They seek advice when needed
There will be points in everyone’s life where they just can’t do it on their own. Highly intelligent motivated people are not afraid to go out and look for help. They don’t let stubbornness keep them from reaching their goals. Oftentimes, the best resource can be a person you see every day. Help them and they’ll help you. Yes, it’s that simple.
7. They don’t set limits
Highly intelligent motivated people never stop trying. They pursue their dreams without worry. Limits don’t exist in their minds. Take a second and imagine where you want to be in 5 years. Don’t worry about how impossible it sounds. Remember, highly motivated people don’t set limits. Now write it down. A highly motivated person would hang that piece of paper up, read it every morning, and work towards it every day.
8. They are grateful
Gratefulness has been shown to improve happiness time and time again. Highly motivated people know this and they practice gratefulness all the time. It helps keep them grounded and reminds them that they also had some help. Try to write down 5 things you’re grateful for every day. It doesn’t matter if they’re big or small – just 5 things you’re grateful for.
What will you do?
As soon as an intelligent person understands something, they start to obsess over the topic and become an expert in it. If they cannot understand it, they attack it until they do or forget about it and move onto something they can comprehend better.
But due to their childhoods, constantly having succeeded were other children struggled, they have been praised throughout much of their maturing lives. They learn that this recognition is part of their identity, and continue to strive for it into their adulthood.
Average people, on the other hand, only get praised when they have tried hard at something. This encourages them to put effort into things for their motivation. At the same time, they are rarely told to take risks: they are told to go to college, get a job, get married, and retire when they’re 66.
They prefer the safe kind of life rather than one that could be interesting, and that usually is what makes them average.
The three Rakat wakter are performed in Esha prayer. In the first Rakat after reading Fateha recite any Surah and the second Rakat will be the same(ie. After Fateha read any Surah). After the second surah you will sit to read.. Attahayat and after that stand-up and read 3rd Rakat (read Fateha and any surah and after it read due kanoot and go to Rakuh and sajda).In case Due Kanoot is not learnt by heart any other Due can be read.
Is having fun during Ramadan considered a violation of the rules?
We have had fun for 11 months so what would be wrong if we forbid ourselves from having fun only for 30 days. Ramadan teaches us to stay away from any kind of fun while fasting. It is a single month of purification, ask forgiveness from Allah Almighty and devote ourselves only for 30 days which is not a long period.
How does social distancing effect Ramadan?
During Ramadan, Muslims attend the mosque nightly to stand in a congregation (foot to foot) for the evening prayers or tarawih. The mosque may have the iftar or breaking of the fast. At the very least, Muslims can greet each other and wish each other a happy and blessed Ramadan. This is the community spirit which is severely altered with social distancing, which started several months ago and affects the weekly, Friday prayers which are obligatory on all Muslim men.
Ramadan comes at a different time every year.
If Ramadan seems harder to predict than Easter or the Jewish High Holidays, there’s a reason for that. Ramadan follows a strictly lunar calendar, and a lunar year is about 11 days shorter than a solar year. So each year, Ramadan begins a little earlier in the annual round.
Easter always happens in the spring, and the High Holidays always happen in the fall (in the Northern Hemisphere). Ramadan moves backwards through the seasons, from summer to spring to winter to fall, completing the cycle every 33 years or so. That means a typical Muslim observes Ramadan in every season as the years pass. If Ramadan were made to conform to the solar year, some of us would have to always endure long summer days of fasting, while others, who always fasted in winter, would barely have time to notice they were hungry.
Don’t worry about us.
Thank you for your concern, but fasting is not dangerous. We fast from sun up to sundown each day, and we are often reminded to eat something just before we begin and at the moment the sunsets. There is no merit in prolonging the fast. Feats of asceticism are not just discouraged during Ramadan; they are universally frowned upon.
Those of us who are pregnant, or who have a health condition that could be aggravated by fasting, are exempt. As we age, most of us get to a point where we stop fasting or only fast briefly. If we have the means, we buy dates and oranges to hand out at sunset, or we pay for our neighbours’ iftar (fast-breaking evening meal).
Fasting is more of a trial during long summer days, so we may feel depleted by late afternoon. But as soon as the sun sets, we break our fast. In most communities, everyone is then invited to a free iftar at the mosque. During Ramadan, the rich and the poor sit together and share the same meal. We all hunger during the day and are filled in the evening.
Don’t hide your food and water.
You won’t offend us by eating your lunch or drinking your coffee in front of us. That is, if one of us does take offence, he or she might as well not be fasting. Kindness and good conduct toward others are more important than denying ourselves food and water. Ramadan is a month-long spiritual exercise, not a conspicuous display of piety or an effort to reach fitness goals. Observing Ramadan does not give me an excuse to demand that other people change their behaviour for my sake.
Besides, the experience of fasting is not a relentless craving for food or drink. The sight or smell of food is not torment. If you don’t believe me, try fasting for a day yourself. I believe you’ll feel different, but not deprived. If you’ve never fasted before, there may be some initial anxiety. But you’ll probably be surprised at how soon you stop thinking about what you thought you needed.
Questions are welcome.
If you’re curious, ask.
Pro tip: If we talk too long or get carried away with a subject, just raise your hand and say gently, “That’s enough.”
Many mosques serve iftar to non-Muslim visitors during Ramadan. (It’s a good idea to call ahead if you plan to come, especially if you are bringing a group.) Hospitality is a very important value to most Muslims. People will usually go out of their way to make you feel welcome.
Unless you are an exceptionally picky or timid eater, I think the food will please you. American Muslim communities are among the most diverse in the world, so you might be served an Arab casserole thing with aromatic rice, or maybe a South Asian curry and samosas, or (my current favourite) a spicy West African goat stew. Or there might be pizza. The greater the number of teens in the community, the greater the odds that pizza will be an option.
Most of us will only ever talk to 911 Operators on the worst day of our lives. They listen to our stories of death, pain, and crime all the while staying professional and calm. The job entails the ability to work under stressful situations, listening to the very worst aspects of life but when the shift ends what happens then? Who do they tell their stories to?
A group of 911 operators shared their unforgettable scariest phone calls. Here’s a selection of the most disturbing tales they had to tell.
1. “I Need Your Help”
“There was an old couple who lived on a run-down ranch house about 20 miles east of town. When the husband passed away, the woman would call 911 Operators at least three times a week, asking for assistance with very mundane tasks not normally dealt with by first responders. “I need help turning the thermostat up”, “I need help boiling water for my tea”, etc.
The woman developed dementia, and eventually, it progressed to the point where she believed she was calling 911 to ask her deceased husband for help. All of the dispatchers would recognize the address immediately, even though all she could say was “(husband’s name), I need help. Please come home and help me”
One day she called, and again was only able to repeat her husband’s (I’ll call him “John”) name. “John, I need help. Please come home and help me, John.” By the time the first responders arrived on the scene, they found the woman lying dead in her bed. The first unit on the scene called dispatch to confirm that it was the woman herself who had called 911, as rigor Morris had already set in. We wrote it off as the fact that the heater in her house wasn’t working, and the ambient temperature in the room was about 50 degrees.
We continued to receive 911 calls from that woman, at that address for just over a year after she passed away. Even after her home was vandalized, and burned to the ground, the phone calls did not stop. “John, I need your help. John, please come home and help me.” We were obligated to send a response each and every time, but not once did we find anyone on or near the property.
Multiple calls to the phone company confirmed that the phone line had been disconnected, and the call was not coming from another address.”
2. Glass Breaking
“1979 NYC. Got a call from a crying child – a little boy – saying his mom and dad were fighting and his dad said he was going to throw the mom out of the window. I could hear a terrible fight going on in the background – a woman screaming, things breaking, a man yelling, etc. The poor kid didn’t know his address. We didn’t have the technology for call ID and would have to use reverse telephone books. A trace would take forever. Anyway, while I’m trying to get the address I hear a horrific scream and glass breaking. A few seconds later the other operators in the room are getting calls about a woman lying in the courtyard who came out of a window. Very sad.
Worst of all is that I am sure someone else in this apartment building must have heard this fight but no one called for help until it was too late. Poor kid. Working 911 Operators in NYC during the 70s/80s was a nightmare.”
3. Alone in the House
“The single worst call I’ve ever taken though was a woman who was calling in that she was hearing weird noises in her house. While walking through her house she started screaming and told me there was someone in her house. There we a couple of soft pops followed by a gurgling sound. After the officers had cleared the house and found her, it finally came out during the investigation that her adult son had killed her while high and freaking out.
Gunshots don’t sound like you’d think on the phone, they’re rather soft. It’s an eerie sound, something so violent being so soft that if you aren’t paying attention you can miss it.”
.
4. Static on the Line
“My uncle works for dispatch in my town and he recently told my family of the weirdest call he’s ever gotten. He says that he had received a call from a landline one night and when he answered it there was only static on the other end. This happened two more times. Finally, he calls a squad to go check out the address from the caller ID. When the cops got there and walked into the house they immediately saw that there was a dead body. The person had been dead for 5 months.
The craziest part about it was that there was no electricity or any other utility working. So there is no way they should have been able to get those calls into dispatch. But if they hadn’t, who knows how long that person’s body would have stayed there.”
5. Mom had fallen down the stairs and wouldn’t wake up.
When I was still working full time for the Fire Dept, I often took shifts working the medical part of the 911 Operators center.
Back in 2006, when flip phones were still the most common, pinning down a location was not very easy. We were still using primitive cell phone location technology which didn’t help as it only gave us a general area of miles instead of feet.
A young girl called in using her mom’s flip phone and she told me that her mom had fallen down the stairs and wouldn’t wake up. After several questions, I figured out the mother wasn’t breathing and this was the scariest part of the call because the girl couldn’t give us an address and when someone stops breathing the second’s count?
As much as I tried, I couldn’t get the little girl to tell me her address. All she could tell me was she lived on a farm which wasn’t helpful at all because a huge portion of my district is rural farmlands.
While talking to the young girl, I asked her how long ago her mom fell down the stairs. she told me that she fell down just after a TV show she was watching started.
I looked at the clock and it was just the top of the hour so piecing it together I surmised she had been down at least 30 minutes.
I asked the young girl to focus and try and tell me where she lives. I asked her if she knew the street name and she said she didn’t. I asked her if she could tell me any landmarks and that’s when she told me that the church she goes to is just down the street.
At this time, my supervisor and the police chief are looking at a map and they located 12 churches within the rural areas.
Since she couldn’t tell us which church, we decided to dispatch all of our units giving each of them a specific target.
Once they got to the target we instructed each unit to turn on their lights and sirens and drive around the area. With only one Fire Station with Two Ambulances and Several Fire Rescue Vehicles and 4 Police Officers to cover a huge area
We dispatched them to cover around the churches as the farmsteads were sometimes miles apart from each other.
Hearing our calls over the radio, several sheriff deputies and highway patrol troopers decided to join in and help. We are now almost 15 minutes into the call.
We told the young girl to take the phone and go outside and listen for the police cars and fire trucks. It seemed like forever, but she eventually heard the sirens from one of the vehicles but couldn’t see it.
We told each responder to stop and turn off their sirens and then, one by one, we had them turn them back on so we could tell which one was the closest to her.
It turned out to be one of the fire rigs so we sent everybody to their position and they then spread out to cover the general area. All with their sirens on again. Eventually, one of the State Troopers pulled onto her street and the girl could see him coming.
We pinned down the location as he got closer and the sirens got louder until she told us he was in front of her house.
This time the Trooper got inside the house the mother was breathing and trying to get her bearings and get up.
We got medical on scene and she was transported to the hospital with a broken back. The young girl was given a little reward from the police dept for her bravery in the call as she kept calm and did everything we told her to do.
The mother made a full recovery with no brain damage, Doctors don’t know if she did indeed stop breathing but only for a short time or if the girl didn’t understand the question and thought sleeping meant not breathing or something.
This call is a reminder, why we don’t stress enough to teach your kids your first and last names, their phone number and phone number of their parents, and most importantly, their home address and If there is a landline phone in the house to use that to call 911 Operators. Overusing a cell phone as the landline phone will give us an exact address. While cell phones are scariest while a lot better now can sometimes only give us a location of several hundred yards.
Vaginal sex typically lasts three to seven minutes, according to a 2005 Society for Sex Therapy and a Research member survey.
According to the survey, vaginal sex that lasts one to two minutes is “too short.” Vaginal sex that lasts 10 to 30 minutes is considered “too long.”
So how long should vaginal sex actually last? The sex therapists surveyed say that anywhere from 7 to 13 minutes is “desirable.”
It’s important to note that these figures only apply to penile-vaginal intercourse. They don’t account for things like foreplay, and they aren’t representative of other types of sex.
It primarily depends on how you define sex time.
Most studies of this nature are based on intravaginal ejaculatory latency time (IELT).
IELT refers to the time it takes a person with a penis to ejaculate during vaginal penetration.
But this isn’t how everyone defines sex. Many people consider the end of sex to be once all involved parties have climaxed.
This may be achieved through touching, oral sex, vaginal sex, anal sex — or a combination.
If intercourse is the only component in your definition of sex, then sex will likely only last a few minutes.
It’s also worth noting that using IELT as a baseline assumes that penile-vaginal intercourse is the standard.
Vaginal sex doesn’t always involve a partner who has a penis.
And although it’s possible to extrapolate these figures to penile-anal intercourse, vaginal and anal sex aren’t the same thing.
More research is needed to determine the average and desired duration for these encounters.
What you want out of an encounter is also important
Sex time should be pleasurable over anything else, and this comes down to personal preference.
Some people want a long, sensual encounter, while others want something fast and aggressive.
The key is that you’re having satisfying sex as opposed to beating the clock.
All that said, you can’t fight biology
In some cases, underlying biological factors may affect how long your sexual activities last.
Age
As you get older, you may find that:
it takes longer to become aroused
erections are more difficult to achieve and maintain
hormonal changes contribute to things like vaginal dryness and decreased libido
Genitalia
The shape of your genitals may also be a factor in sex time.
Researchers in one 2003 study found that the shape of the penis — specifically the ridge around the head — may have evolved to be more competitive.
The ridge is able to displace any preexisting semen in the vagina. Deeper and more vigorous thrusting results in more semen displacement.
This allows the ejaculating partner to make room for their own semen, increasing their chance of reproduction.
Using competitive evolution as a backdrop could explain why some people find it painful to keep thrusting after ejaculation. Continuing to thrust may displace your own semen and decrease your chance to reproduce.
Sexual dysfunction
Premature ejaculation, for example, can cause you to climax faster than you may prefer.
People with delayed ejaculation may take longer to climax if they’re able to at all.
If you want shorter encounters
If a quickie is all you want, these techniques may help you get there faster.
Touch yourself
If you’re short on time, masturbation can be a great way to ensure that you achieve the Big O. After all, you know your body best!
If your partner is already touching you, explore a different area. You can:
rub your clitoris
gently pinch or pull your nipples
gyrate your hips
smack your behind
You can also enjoy mutual masturbation, in which you each pleasure yourselves.
This gives you both the opportunity to climax faster while still being intimate.
Tell your partner what you want
Communicating your desires to your partner — and vice versa — can help you both understand what it takes to make each other orgasm.
You can utilize what you learn to get to the finish line faster for mutually gratifying quickies.
Try climax-inducing positions
If you know that certain positions feel better for you than others, shift as needed to get yourself there faster.
This can include positions that encourage deeper penetration or those that make it easier for you to manually pleasure yourself or your partner at the same time.
If you want longer encounters
If you want to prolong your exploration, these techniques may help.
Semans’ stop-start technique
Also known as “edging,” this involves temporarily stopping all sexual stimulation when you feel like you’re close to ejaculation.
You and your partner can resume your activity once this feeling has passed.
Although this technique was originally founded to help a person who has a penis delay ejaculation, it can be used by anyone looking to prolong climax.
Johnsons’ and Masters’ squeeze technique
This technique entails gently squeezing the end of the penis for several seconds just before ejaculation until the urge subsides.

The bottom line:
The definition of what sex is, individual expectations, and mutual desires all influence how long sex may last.
If you’re concerned about how long you’re able to have sex, consider making an appointment with a doctor or other healthcare professional.
They can discuss how you’re feeling, answer any questions you have, and assess any underlying symptoms or other discomforts.

Sorry, no. First, most of
the superpowers shown in the
comics are impossible(flying
without wings,laser vision,
telekinesis, etc.).
Some others are not, but are
beyond the reach of mutation.
