It's even worse. The original US Constitution does not prohibit slavery. It wasn't until the Thirteenth Amendment was passed seventy years later - after a Civil War tore apart the country - that slavery was abolished. With the express exception of punishment for a crime. No qualifications for the severity of the crime. And that exception gets frequent use to this day in the penal system
The Star-spangled Banner (where the phrase “Land of the Free” comes from) was written in 1814, 51 years before slavery was abolished. The idea that America is or ever was the land of the free is a total joke.
The third verse of "The Star-Spangled Banner" is not typically sung today. It refers to "the hireling and slave" among the foes of the Republic. "The hireling" refers to the mercenaries employed by the British crown in fighting the American revolutionaries. It is unclear whether "slave" is intended to derogate all British subjects as "slaves" of the crown, or if it specifically refers to enslaved Africans who were offered their freedom by the British if they fought against the revolution.
… and built its initial wealth on slavery revenue.
It’s a shame because there are a lot of other great things to be proud about when it comes to the US. I guess when people boast about US freedom, what they mean is democracy, and starting the end of the colonial era, inspiring a tidal wave of democratic uprisings around the world, which is accurate. I wish they didn’t use the word “freedom” for that.
That's not all that exciting. All of Europe (and basically every other are of the world) was built on slave labor as well, that's literally what the colonial period was about. Also vikings were primarily about capturing slaves, Rome and Greece were mostly slaves, serfdom wasn't significantly different than slavery.
Many companies are making profits off of this. So many states have for profit prison systems and will get fined of they don't have enough people in those prisons. That is above the free labor most people have talked about.
Life, liberty, and the pursuit of happiness are not subject guarantees in any United States territories. Misuse of free will may result in the loss of life, liberty, and the pursuit of happiness. Symptoms may include mental disease, tissue damage, cancer, and loss of all bodily and livelyvhood functions. Consultation with appropriate legal counsel is recommended before using free will, as complications may occur.

Wait, you're saying that the Aztec empire was just 64 years old when Columbus discovered America and ships with conquistadors followed to butcher and enslave everyone?
If you've ever played around with an old-style lighter (think classic Zippo) you'd get it! They're fairly expensive, and aren't airtight so they need to be refilled every few days/weeks. If you fill them too much they need to be kept upright or they'll spill lighter fluid on you. Super cool and can hold flames for a while but not nearly as conventient as a matchbook for quick fire lighting
My grandfather clock is correct* about once a week when I wind and correct it
*It must be correct as it's very slightly fast (less so than can be fixed with a quarter turn off the pendulum screw) and I set it slightly in the past
Nuclear power causes less deaths (per energy unit produced) than wind (source)
You get less radiation when living near a nuclear power plant, than if that nuclear plant hadn't been there.
To explain the second: A major misconception is, that nuclear power plants are dangerous due to their radiation. No they aren't. The effect of radiation from the rocks in the ground and the surroundings is on average 50x more than what you get from the nuclear power plant and it's fuel cells. (source). Our body is very well capable of dealing with the constant background radiation all the time (e.g. DNA repairs). Near a power plant, the massive amounts of isolation and concrete will inhibit any background radiation coming from rocks from that direction to you. This means, that you'll actually get slightly less radiation, because the nuclear plant is there.
Regarding the dangers of nuclear disasters. To this day, it's been very hard to find out, if at all any people have even died to Fukushima radiation (ans not other sources such as tsunami/earthquake/etc.) Nuclear radiation causes much more problems by being an emotionally triggering viral meme spreading between people and hindering it's productive use and by distracting from the ironic fact, that the coal burned in coal power plants spew much more radiation into the atmosphere than nuclear power plants themselves. (source)
To this day, it’s been very hard to find out, if at all any people have even died to Fukushima radiation (ans not other sources such as tsunami/earthquake/etc.)
Truly no offense, but this is sort of burying the lede on Nuclear Power risks. Mathmatically coal releases more radiation - no question. It's also hard to pin down how many died due to Fukushima for ver good reasons: Correlation might be easy, but determining cause is ultra tough and no right-minded scientist would say it without overwhelming evidence (like they had something "hot" that fell on their roof and didn't know it for a long time). Also? They aren't dead yet. So we look to statistical life span models crossing multiple factors (proximity, time of exposure, contaminated environments and try to pin down cancer clusters attributable, and people can live for decades, etc....
The problem is that people rightly are concerned that in both Fukushima and Chernobyl (and 3 Mile for that matter) unforseen circumstances could have been catastrophically worse. You blow up a coal plant? You expose a region locally to it and it's probably "meh". You blow up a nuclear plant, and you get melt down corium hitting ground water or sea water with direct exposure to fissioning material and all the sudden you have entire nations at risk for subsequent spewing of hot material that will contaminate food supplies, water resevoirs, and linger on surfaces and be pulled into our lungs once it's in the dirt. Radioactive matieral is FAR more dangerous inside the body when you eat plants and animals that are exposed and pull it from the ground. Even cleaning down every surface, eventually you'll get some of it airborn to be breathed into our lungs again with wind storms, flooding and other natural erosion. The consequences are exponentially higher with Nuclear accidents and ignoring that is whitewashing. And that's not even getting into contamination from fuel enrichment, cooling ponds/pools leaking water, or the fact that it will take 30-40 years to clean up Fukushima (and they aren't sure how exactly that will happen and there could be another tsunami). Probably hundreds to try to clean up and contain Chernobyl - and given the current state of affairs we may find out even worse.
BTW, I'm pro-nuclear. Thorium salts seem a good way to go and we probably would already have these if not for the nuclear arms race making nations hungry for plutonium. Please don't short sell everyone's intelligence because you can claim "only" a handful of people died due to Fukushima. Direct death is only one facet. Lives were disrupted (and displaced) and for a while there, the impacts spread to the US across the Pacific and there were discussions of evacuating like 1/3 of Japan's population outside an exclusion zone. You can be pro nuclear while still acknowledging that some fears are real and well founded, and unfortunately the industry has proven gaps in safety that make it harder and harder to argue when we have Solar and Wind and rapidly ramping power storage. Nuclear is likely to simply be outcompeted over time (just like Coal and NG).
Iv read about Thorium the last 3-4 years and it seems so promising. Im really disapointed that the push is not greater as it would make everything a lot more safe.
Additional fun fact. There has been a lot of research and activity dedicated to potentially switch coal power plants to nuclear. Currently, they cannot do it, because the coal plants and all the equipment associated produces far more radiation than regulations allow a nuclear plant to emit.
Therefore, unless they could find a practical way to decontaminate the radiation away from existing coal equipment, or regulations change for transformed plants, they can't do it.
Did you know, the Nuclear Regulatory Commission's only mandate is to ensure the safety of nuclear power, not to promote its implementation. Many regulatory bodies have a dual mandate to stop them from just shutting down what they're supposed to regulate.
What are you trying to say by linking this article?
I mean, it even says that it was a mechanical issue - and the radiation danger was low. And even then, it's just a single person. Looking at the bigger picture, the numbers game favors nuclear+wind+solar over fossile.
Nuclear power is actually the cleanest way to produce energy. The waste from replacing solar panels and windmills (which have a service life only three to five years) is actually more of a problem than the waste from spent fuel rods. Plus environmental impacts from fuel rod production are less than solar panel and windmill production. The problem with nuclear energy happens when things go wrong. It would have to be absolutely accident free. It never has been and never will be.
Though they're on the right track with nuclear power. Fusion would be ideal, runs on seawater (fuses deuterium/tritium) and if there's a problem you simply shut off the fuel. Problem is insurmountable engineering issues, we just don't have tech for it yet (need anti-gravity). They've been working on it for many decades and progress has been painfully slow.
Windmills last much longer than five years. They generally last 20-25. Wherever you heard that bullshit number from, ignore all the other info you got from them.
Even when things go wrong, it's not as bad as with the other classic fossile energy sources. Exactly this calculation is included in the world in data source on deaths per kWh which I linked.
When we have car accidents normalised, massive climate change, air pollution from fossile fuels, then even the occasional nuclear accident isn't really a problem.
The problem is, that these accidents get much more attention than they deserve given how many deaths are caused by fossile fuels. When calibrating for deaths, fossile fuels should get around 100x the attention
There are people still alive who remember a world before "splinter-free" toilet paper.
The manufacturing of this product had a long period of refinement, considering that as late as the 1930s, a selling point of the Northern Tissue company was that their toilet paper was "splinter free".
On average that is. Mercury is actually the closest planet to every other planet in average. Because when it’s on the other side of the Sun, it’s still pretty close.
The average distance from Earth to Mercury is about 1.04 astronomical units (au), which is the average distance between Earth and the Sun.
In comparison, the average distance between Earth and Venus is approximately 1.14 au, while the average distance between Earth and Mars is around 1.7 au.
How can that be? I mean if that is true than at some point Earth Venus and Mercury will align in such a way that Mercury occupies the 2nd position not the 1st right?
Your car keys have better range if you press them to your head, since your skull will act as an antenna. It sounds like some made up pseudoscience that would never work in practice or have a negligible effect, but it actually works.
Edit: idk if it's actually because your skull acts as an antenna, although that's what I've heard. I looked it up and it seems like it's your head acting as a reasonance chamber. Since your body is conductive, your head can bounce and amplify the radio signal.
On one side you have people that think 5g causes cancer. On the other, you have people directly beaming shit into their skulls to open their cars from a couple extra feet away.
To be fair, radio waves have been everywhere for over a hundred years now. Plus, it's just low-frequency light. It's no different (probably safer even) than shining a flashlight at your head.
Hold your fob a foot to the side of your head. Back away until it stops working. Take 2 more steps back to be sure. Then put the fob to your forehead. It'll work again.
It's true, but not because your skull acts like an antenna. It's because the signal is being reflected by the skull. You can actually just try it out, the range of your car keys will extend when you hold them to your chin.
Next time you're in a parking lot, try to click your fob from a distance where it doesn't work. Then hold it to your chin or skull and click it. It almost doubles the range.
If you start to think about how these lengths of time are defined it becomes clearer.
1 day = time to rotate on it's axis once
1 year = time to complete a full rotation around the sun
For Earth, it takes us ~24hrs to rotate on our axis and 365.25 days to orbit the sun.
However, because Venus' axial rotation is so slow (and another interesting fact, it rotates in the opposite direction to other planets) it actually completes a full orbit of the sun before 1 axial rotation.
Hence, a year is shorter than a day
For those interested:
1 Venus day = 243 earth days
1 Venus year = 225 earth days
Colloquially, most people use “day” to mean how long it takes the sun to get to the same place in the sky. Solar day vs sidereal day, the difference is only about 4 minutes on Earth, but can be much greater elsewhere. Venus’ solar day is about 117 Earth days, so you would see a couple sunrises/sunsets each Venusian year.
Oh no. For some reason I thought we were manufacturing the sand used in construction and stuff. At what point do we stop stealing it and start making it? Is that actually any better?
General Motors, Firestone Tire, Standard Oil, and Phillips Petroleum were convicted of an actual conspiracy related to the monopolization of transit systems, which replaced beloved streetcar (rail) systems with rubber-tired oil-burning buses.
This is a simple statement that the space between the earth and the moon can allow for the diameters of each planet to fit in between. Obviously it is not saying that such an arrangement would be stable for said astronomical bodies. Not at all “a misconception.”
Now you have me wondering if there's any combination of paths that would have them all pass through that alignment and continue on their way after slingshotting around each other. And, if not, how many bodies could do that.
Not sure when this became a thing, but it feels relevant and might be useful to someone someday.
a formerly homeless friend once showed me that taking a brick and grinding it on top of the can, will open it without a knife. the 'ridge' of the can, the metal circle that runs along the diameter at either the top or bottom, is a metal 'lid' that's folded or pinched shut onto the other piece of metal, the 'cup'. (single quotes around terms i picked and might not be official jargon)
in just a few minutes, the brick ground the metal off the ridge, seperating the lid from the cup, which easily popped out. technically you don't really need any tool, just some relatively flat concrete or a rough flat rock. or even low grit sandpaper.
i don't recommend tossing out the can opener though, there is a chance of metal shavings falling in if you aren't careful. still might be useful in an emergency.
Many Swiss Army knives have a can opener. You hook a part of it under the can rim and it acts as a lever for the small knife blade above it. You simply work your way around the can, cutting the lid a bit at a time. I've done it many, many times. It's safe and easy.
I once read a blog from a sailing group that pointed out that there is possible sea route where you could sail from Halifax, Nova Scotia in a straight line and end up in Vancouver, British Columbia.
I don't think this is true for all of them. My cube takes at least a couple hundred rotations and then you have to take the stickers off and move them around to solve it.
In english generally we see liquids to be the same as fluids but technically liquids are a state and fluids are matter that flows. Similarly we will see accuracy and precision as the same thing but accuracy is within a range where precision is exact.
As an example: Strawberries and raspberries aren't even berries but pumpkins are botanically speaking. I would be accurate to regard strawberries and raspberries as berries as we use them as berries but I would not be precise.
Water is actually a very unusual substance. When it freezes into a solid, instead of becoming heavier and sinking in liquid water, it begins bouyant and floats.
If it didn't have this property, our planet would have turned into an ice ball and never thawed out.
Well, no; Theophania was a common Christian name in the Eastern Roman Empire. "Tiffany" is an English version of Theophania, a Greek Christian name referring to the feast day also known as Epiphany or Three Kings Day. The masculine form is Theophanes.
"Jennifer" is, by the way, the English form of the Welsh name Gwenhwyfar, also known in French as Guinevere.
if you scramble a rubiks cube up there is a good chance that it is the first cube to be in that state.
there are 43,252,003,247,489,856,000 possible states that a cube(3x3) can be scrambled up in to.
Hand sanitizer is ~120 proof alcohol.
(Not a recommendation to drink it, since it's usually spiked with bad-tasting additives to keep people from doing just that. Some commercial hand sanitizers swap out ethanol for isopropyl alcohol, i.e. rubbing alcohol, which is more toxic when ingested.)
Not all sanitizers are alcohol based. Some are chlorine based and probably other kinds too. The cheap ones during covid that smelled like shit vodka were definitely ethanol based though.
During the covid quarantine many alcoholic beverage companies in my country temporarily switched production lines to hand sanitizer using some of the same raw materials. The result were hand sanitizers and alcohol that had the weirdest smells.
Until recently the word "factoid" didn't mean a small bit of trivia. It meant something that sounded true or was accepted as a fact even though it was incorrect.
The formula used to prove the functionality of magnets can also be used to prove the existence of a theoretical state called a monopolar magnet - positive or negative on both sides. So either monopolar magnets can exist, even if in some esoteric circumstance, or we don't know why magnets work.
This seems like a false dichotomy. Maxwell's equations don't say anything about where the charge comes from, only how the electromagnetic field behaves if charge (be it electric or magnetic) is present.
And if you're talking about the standard model, well we've known that that's incomplete since its inception, but I'm not aware of any argument that says anything beyond the standard model must have either monopole or a fundamentally different conception of magnetic dipoles.

You realize that ChatGPT has no concept of "true", right? It produces output which looks coherent and reasonable and tends to stumble into truthful statements on accident, by virtue of drawing from a dataset of people saying mostly true things. Of course, the bot is equally capable of spouting off outright lies in an equally convincing manner.
This is a very unreliable way to verify a surprising fact. I strongly recommend against it.
Yes, your statement is quite accurate. The field of magnetism, like many areas of physics, continues to provide plenty of mysteries and unanswered questions.
Monopoles, magnets with only one pole, are a purely theoretical concept at this point. They were first proposed in the context of quantum mechanical systems, and the equations of electromagnetism do allow for their existence. However, despite many years of searching, no monopoles have been detected so far in the real world.
As for understanding how magnets work, we do have a rather good grasp on this from the framework of classical electrodynamics (Maxwell's Equations) and quantum mechanics. It involves the alignment of electron spins in certain materials, creating a net magnetic field.
However, like many theories, while it predicts observable phenomena remarkably well, it still doesn't answer every question we have about the nature of magnets. It should also be noted that our understanding of magnetism (and most physical phenomena) is based on models which are representations of reality and not the utter, standalone truth. So there is always room for additional discovery and understanding.
Remember, the lack of a complete explanation doesn't necessitate that our current understanding is incorrect, it merely implies it may not be complete. Science is an ongoing process of learning, refinement, and discovery.
I don’t know you are downvoted because ChatGPT answers are usually a good start for a new conversation and new arguments. Is ChatGPT answer accurate, is it somehow true but with a lot of hallucinations? What about the nuances in its answer they we might have overlooked?
There are four stanzas to the Star Spangled Banner (the US national anthem) and what you typically here at sporting events is only the first.
Bonus fun fact, the fourth stanza contains the line that, in the 1860s became the shorter, "In God We Trust," motto on coinage that eventually became the national motto of the US in the 1950s (which was also when it was added to paper money). That original line from the fourth stanza was, "And this be our motto - 'In God is our trust.'"
The first can/tin opener wasn’t invented until about 75 years after canned food started being produced. During that time, people used hammers and chisels to open cans.
Capital cases cost a ton more to prosecute and defend and there are a lot more rounds of appeals. When someone’s life is on the line, we jump through extra hoops as a society.
Wait why? I thought that was only a thing if you get close to a black hole. Why would it be a serious concern? Couldn't you just avoid the black holes?
That would be a diameter of about 800 km. Don't they have multiple centers that could be called towns? With churches, administration and schools? They just can't be bothered to split it up.
The towns in this municipality on Greenland used to be split up. The main capital is among them, so it made sense to grasp the 800 km circumference even if it's just a few people. Anyway it's according to the topic, so as stupid as it might be, it is factually the largest cities by area, and goes to show that the question of which is the largest city is ambiguous.
Tokyo is usually considered the largest city, due to the largest population overall, but it doesn't have the largest area (Greenland) nor the largest population of a single municipal (Chongqing, China) nor the largest density (Macau, China) nor the largest area of skyscrapers (Hong Kong), so it's a thing depending on definitions.
It doesn't really matter much. If you're in the middle it, it's all just city until the horizon. Well, except for Greenland. You can probably throw a stone across all the houses in the largest city by area.
Actually a lot of the maps you are used to seeing do not accurately depict the land size a lot of countries. Mainly USA, Canada, and Russia. Google it.
It's not easy to say whether it is or not. This is something called the Liar Paradox and it has a surprising amount of potential solutions. That article linked explains it really well but, be warned, it is a bit dry.
The solution one of my professors gave that makes most sense to me is that, as a standalone sentence, "this sentence is a lie" is neither true nor false. At first glance the sentence makes sense and "lie" leads us to think that there is an untruth somewhere but there can't be as there is no 'truth value' within it. That is to say that there is nothing in the sentence that can either be true or false therefore there is nothing that can be lied about.
Only one of many potential solutions so though. So, maybe?
A fairly large amount of traditional Italian dishes aren't Italian. Many of these, such as carbonara, pizza, and tiramisu, were actually invented in the US, and only became known in Italy sometime in the mid-late 20th century.
Many of these, such as carbonara, pizza, and tiramisu, were actually invented in the US
From the article you cited:
Pizza is a prime example. “Discs of dough topped with ingredients,” as Grandi calls them, were pervasive all over the Mediterranean for centuries: piada, pida, pita, pitta, pizza. But in 1943, when Italian-American soldiers were sent to Sicily and travelled up the Italian peninsula, they wrote home in disbelief: there were no pizzerias. Before the war, Grandi tells me, pizza was only found in a few southern Italian cities, where it was made and eaten in the streets by the lower classes. His research suggests that the first fully fledged restaurant exclusively serving pizza opened not in Italy but in New York in 1911. “For my father in the 1970s, pizza was just as exotic as sushi is for us today,” he adds.
It clearly states something different than your claim. Pizza was not invented in the US, it was popular in the US.
From Wikipedia:
Modern pizza evolved from similar flatbread dishes in Naples, Italy, in the 18th or early 19th century.[31] Before that time, flatbread was often topped with ingredients such as garlic, salt, lard, and cheese. It is uncertain when tomatoes were first added and there are many conflicting claims,[31] though it certainly could not have been before the 16th century and the Columbian Exchange. Until about 1830, pizza was sold from open-air stands and out of pizza bakeries.
Many sources state pizza wasn't popular in Italy as it was in the US, but your statement on it's origin is 100% wrong.
This is not stated accurately. The American versions of pizza and carbonara we're invented in the US, but there were and are original Italian versions.
Nikola Tesla loved a pigeon so much he spent todays rough equivalent of $34,970 on her happiness.

That's pretty disingenuous, since most files aren't just random data.
Most real files actually have rather low entropy, even if they look like random junk (e.g., executables), chiefly due to repetition of similar data and sparse values.
Is it because it works on patterns and your random garbled string would have too much noise to be compressed well, while a structured file coming from an actual piece of software would probably have enough repeating patterns to the point where it actually can be shrunk?
the ups and downs are battling hard on the parent comment. gotta admit, I had to think for a few seconds to get the gist of it, but its actualy pretty slick and perfectly snarky.
edit: only thought would be that an infinite selection of random data sets would be somewhat evenly split between compressable and non-compressable, but if you add compression structure, it tips the balance firmly into "file size increases" territory.
