Reply to comment by TheLuminary in ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside
This is called mip-mapping by the way, and in modern games this process happens all the time.

Reply to Eli5: Saving difference problem by theBloodsoaked
A month does have *roughly* four weeks, not exactly. Take a look at a calendar and see for yourself. Or do the math with the number of days: a week has always 7 days. A month has 28, 29, 30 or 31 days. 28 is 4 weeks, 31 is more.

Pretty much, yes
Off the top of my head, I dunno how much sooner, but the "double its length" is spot on

4x12 is not 52. You’ve made an assumption about the relationship between months and weeks. There are 52.18 weeks in a year.

There are not 4 weeks in a month. 4 weeks is 28 days, which is a bit less than every month except a non-leap-year February.
A closer estimate would be 4.5 weeks in a month, which would be $45 a month times $12 = $540, fairly close to your (correct) $520 computed by just using the number of weeks in a year. (Although, strictly speaking, there are 52 weeks + 1 or 2 days in a year, depending on whether it's a leap year.)

Reply to comment by [deleted] in ELI5: Why do we take that deep, involuntary breath when idle out of nowhere? by respectcrazy
I’ve seen baseball pitchers often take a deep breath before they pitch. It’s clear that their deep breath is relieving pressure or tension. It seems to function similarly in OP’s “out of nowhere” state. For me, it seems to relieve stress… like a deep sigh. Something of a ‘relaxation reset’.

> It's just a natural process called "Boyle's Law", something we've learned from physics and chemistry.
Example of it in action here.

What specifically has she said? What was the context?
Edit: Sorry, not playing dumb here I just literally knew nothing about this. I thought this was something new but apparently this has been ongoing? I guess it just started showing up again because of the release of the new Harry Potter video game. I don't really care for the Harry Potter series and I don't follow celebrities on social media

'organic' and 'natural' are dangerous words to use, as they don't really mean anything, and often are worse for the environment than synthetic chemicals.

Even nano-gold, like is found in sea water?

Did you copy/paste that or was it 100% you? That was one of the best responses I’ve ever seen. I read it three times just to hear the words in my head a few times. Nice job

Boyle's law: 'The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.'
Boyle's law has nothing to do with water absorbing gasses.

Fertilizers give nutrients into the water. Since there are more nutrients, more algae and other plants grow. But eventually the nutrients are consumed and then the algae die. Then microorganisms decompose the dead algae/plants and in this process oxygen is consumed.
Hence, overall oxygen levels decrease.

Usually nutrients are the limiting factor in keeping plants from growing. Add a large amount of nitrogen and phosphorus and they no longer are the limiting factor. Oxygen in the water becomes the new limiting factor.

DNA mutations aren’t always a bad thing. Sometimes mutations can offer benefits. Think about evolution. Species evolve thru genetic mutation over generations and generations.

Modulus of elasticity is a measure of how much something stretches when a force is applied provided you don’t stress it beyond its elastic capacity. It often correlates with strength, but not always.
To calculate how much something will stretch under a force:
Extension = Force x Length / (E x Area)
Wood has a decent modules of elasticity for its weight, but it’s E is lot less than most building materials. Something like 2-8% that of steel depending of species.

JK Rowling has said some statements regarding trans people that some people consider disparaging.
Thats it. Thats all.
She's a massive celebrity's, so the story just keeps going anytime anyone mentions Harry Potter or trans people its a super easy narrative for any media org or person just to toss out her name.

Reply to comment by PerturbedHamster in ELI5: In simple terms what are Maxwell’s equations and how do they work and what do they mean? by whocaresfuckthisshit
In case it's not clear in the above comment a magnetic field arises from the movement of charge--it doesn't matter if you move past the charge or the charge moves past you.
Suppose, we put a charge on a train, and have two sets of electric and magnetic field detectors. Put one set of detectors on the train next to charge, and another on the platform of the station.
When the train is sitting at the station, both detectors will measure an electric field and no magnetic field due to the charge.
Once the train starts moving, the detector on the train will still measure an electric field, but no magnetic field. The detector at the station will measure both an electric and magnetic field.
Repeat the experiment, but this time put the charge on the platform. You get the same result except it is the train detector which will measure both the electric and magnetic field while the detector at the station will measure only an electric field.
Whether or not you measure the magnetic field is dependent upon your reference frame. This was one of the ideas which inspired special relativity.

Reply to ELI5: What's with all the headlines about J.K. Rowling and her thoughts on trans people? by Chief_B33f
Lots of people who felt like underdogs, including LGBTQ+ people, fell in love with Harry Potter.
And now the author is basically saying that transgender women are a dangerous threat.
This encourages violence against transgender women. And it encourages assholes who think that transgender women shouldn't be allowed to use public bathrooms. Which, followed to its logical conclusion, basically means that they can't go out in public. Because humans need potty breaks.
Transgender women have long lived lives on the margins of society. Often with no possibility of finding work or making a living other than by prostitution. Often murdered in the streets and no police even bothering to look for a killer.
The suicide rate among transgender people was as high as 50%. Think about that. It can be so stressful to be forced to inhabit a gender role and a body that don't fit, and to have no one see you, that people end their lives. Imagine if you were forced, for the rest of your life, to dress and act as the opposite to your gender and even your own family went along with it. Imagine looking down at your body and its all wrong. And if you even make the tiniest protest, they call you crazy. It is too much for so many humans. Those who managed to get through it and make a good life for themselves are heroes.
Finally, with medical advances, where endocrinologists and psychologists came to agree that transgender people are not only perfectly sane, but that they can often be identified in childhood, and just raised in their actual gender with the potential to use hormones to make their bodies match their minds. It revolutionized things. Suddenly we have extensive medical literature on how to identify these kids and how to treat them, and the treated kids almost all grow up and are healthy and stable. Whereas before, half of them would die.
We were on the cusp of a world where transgender people could just get the care they need to actually be comfortable in their bodies. Where they could have non-discrimination laws that let them get and keep good jobs. Where their families would see them and support them.
It's such a difference to see these confident young kids and to contrast it with the battered and traumatized people who managed to survive in previous generations. It's night and day. And people like me want more day. More happy innocent kids who worry about what college they'll go to instead of living (and dying) on the streets.
And then JK Rowling starts using her bully pulpit to promote these hateful, medically inaccurate, myths. And the hate that gets frothed up results in politicians cutting off medical care for transgender kids, pretending to care about the complex medical decisions parents make for their kids, pretending to understand or care about the state of the art in this tiny field of endocrinology. (You don't see politicians getting involved in the chemotherapy drugs of teens-- even though those can cause sterility, and future cancer risk, and brain damage. Why doesn't the news cover all those pediatric cancer doctors with the same skepticism as the pediatric endocrinologist at the same hospitals?)
It's bull. I'm a biologist with 15 years of lab experience and I can tell you: gender is a spectrum. There have always been humans that don't fall into the two main categories. Transgender people, intersex people, people with all manner of genetic differences that make them medically NOT ordinary men or women. And those people have been studied (and not always respectfully) ever since medicine was invented. They are real, and they don't want to be hidden away or turned into side-show freaks. They want to live their lives and get their damned medicine.
People like Rowling can take their bigotry and stuff it!
So that's me, one person in the LGBTQ+ community, on why Rowling is a big deal.
