During my childhood, there was a time where my sister's cat (Mittens, due to being almost all black with white paws) would deliberately jump on a chair and dangle his tail down, to be attacked by another cat (Tiger, despite not looking like one). Tiger died quite early, for unclear reasons after being outside all night. When a new cat entered the mix (Buffy, name origin unclear - this was well before the vampire-hunting teen from either movie or TV show), Mittens would try to do the same thing - dangle his tail down to be played with, but the new cat wasn't playing ball. It was an extra layer of sadness I still recall, somewhere around 30 years later now.

You can compel a company to print metric, but you can't compel them to not print imperial.

So a legally compulsory switch just isn't possible in the US.

I don't see any real path to a complete switch, because the units simply aren't that important in day to day life. Whatever you're used to works.

+5 13. Thanny commented 228 days ago on video Top 20 Country GDP (PPP) Ranking History (1980-2023)

Note that this comparison is not GDP, except for the US. It is GDP scaled by purchasing power or cost of living, in comparison to the US.

In the simplest terms, if it costs half as much to buy things in China as the US, then China's GDP is doubled for this ranking.

Actual GDP is about $20.6 trillion in the US, and $13.4 trillion in China, as of the end of 2018.

The PPP measure is very imprecise, because it's impossible to come up with an objective cost of living comparison, and all the estimates are flawed in one way or another.

I also wouldn't trust the projections too much. Cost of living goes up as an economy becomes more advanced.

+8 28. Thanny commented 1 year ago on video Help! My Kid's A Socialist

Socialism is nothing more or less than a group of people pooling a resource to accomplish a goal for the individual members of the group that each alone could not accomplish. The very concept of government is socialist - the pooled resource is authority, and what's accomplished is a modicum of order.

Capitalism and socialism are not mutually exclusive, and there's not a single nation on this planet that is not a mixture of both. And they are both needed, because capitalism, while good for innovation on the whole, due to its evolutionary mechanisms, is bad for equality. Socialism is needed to rein in the excesses of capitalism, taking some of the fruits of the lucky winners and making a safety net for the unlucky losers. It's also needed for the basic fabric of a society. You don't have much of a nation without a military, law enforcement, transportation infrastructure, etc. - all socialized goods and services (and much of it outsourced to capitalist enterprises, such as construction firms to actually build the infrastructure paid for by the pooled public resources).

This guy's understanding of the issue is just as simplistic and misguided as that of the brainwashed students.

I hate the Netflix UI. I don't want the screen to shrink into the corner, making it impossible see the credits. If you cursor over and select the little screen to maximize it again, you've likely missed what you were looking for. So just rewind, right? No, because it shrinks again when it reaches the credits, so you still miss what you were trying to see. And if you do manage to get to the spot you wanted, and pause to allow reading something, the background fades, killing contrast, and blocking parts of the screen with an info popup.

I also don't want some stupid clip to autoplay when I pause on an item. I just want to read the summary. I don't want the movie or episode to start playing automatically when I select it.

The Netflix UI used to be simple and functional. It's a horrific mess now.

-2 44. Thanny commented 1 year ago on video Gun owner "destroys" rifle after Florida shooting: ‘Now there’s one less&rsquo

#12 No, it absolutely is the correct statistic.

The question isn't whether or not homicides are committed more often with guns than with other weapons, in the presence of ample guns. The question is whether more homicides are committed due to the presence of guns. One questions is about how effective guns are are killing people, which has an obvious answer. The other is about whether or not having guns makes people kill other people more often, which doesn't have an a priori obvious answer. The actual answer, however, is that it doesn't, except in the way indicated in my comment - the lack of a weapon at hand will prevent a spontaneous homicide. The absence of a gun will not prevent any premeditated homicide.

So your problem is that you're failing to distinguish between homicides committed with guns and homicides caused by guns. It's actually quite dishonest to act as if they are the same thing.

Furthermore, the United States is a large nation. The homicide rate varies considerably from one location to another. It's worst in poor neighborhoods of large cities, inhabited mostly by blacks, who are more than half of all perpetrators as well as more than half of all victims, despite being only about 13% of the population total. Take those homicides out of the stats, and the US is middle-of-the-road in terms of homicide rate (there are other hotspots that, if remediated, would reduce the rate even further). So the bulk of what we have is a black on black violence problem, not a gun problem. Solving that problem is no simple matter, as there are many factors that contribute to its existence (inherent racial characteristics aren't among them, despite what alt-right idiots claim). What's clear, however, is that no amount of gun regulation is part of the solution.

Lastly, armed citizens is historically important in the United States. The first thing the British did to trigger active conflict in the Revolutionary War was go after the guns - trying to prevent the citizens from taking up arms. Many of the fighting forces during the war were private militias, too. And it was as recently as the 1940's that private citizens had to take up arms to fight government corruption, when a sheriff stole the ballot boxes during an election to avoid losing (the private citizens, after a gun battle, secured the true election results, and got rid of the corrupt sheriff). It may sound like crazy talk to some, in this day and age, to suggest that guns are for the prevention of tyrannical government, but it's as true as it ever was.

0 45. Thanny commented 1 year ago on video Gun owner "destroys" rifle after Florida shooting: ‘Now there’s one less&rsquo

The state of Vermont has some of the loosest gun regulations in the US. There are no gun licenses. Everyone is just allowed to go buy guns.

The murder rate in Vermont is about the same as that in Finland and France.

The phrase "Guns don't kill people. People kill people." is not just some stupid NRA slogan. It's what the actual facts show. There is no correlation between the number of guns in a population and the number of homicides. The only thing having more guns around does is make it the tool of choice for homicide, because it's better at the task than most other tools. That's also why most suicides are undertaken using a gun.

That's not the say there aren't any homicides which wouldn't have taken place in the absence of a gun. But that's also true for other weapons - if that fire poker hadn't been there (or knife, frying pan, marble bust, etc.), she wouldn't have bashed his head in. It's also true that the presence of a firearm has prevented homicides (and other crimes).

What this video shows is abject simple-mindedness - an emotional reaction to a tragic event which nothing short of magically making guns disappear from the face of the earth would have prevented (he'd have had to get a sword instead, or perhaps decide to build a bomb).

Without exception, all of the proposals for new regulatory laws by anti-gun advocates would, if enacted, have made no difference whatsoever in the tragedy du jour they've chosen to exploit.

+2 49. Thanny commented 2 years ago on video The Pemmy Floor Project

There are a few variety of pennies worth thousands or even tens of thousands of dollars.

A couple of them require weighing the penny to determine what it's made of. If it's from a particular year and has a particular weight, it's worth a small mint.

Now imagine learning this and then seeing copies of that year staring up from under all that lacquer, and having to resist the urge to dig them up and check.

1983, incidentally. If you weigh a 1983 penny and it weights 3.1 grams instead of 2.5 grams (copper alloy instead of copper-plated zinc), it's worth a whole lot more than 1 cent.

A 1944 penny made of steel is worth even more (supposed to be copper), but that's obvious without weighing it. Worth slightly less is a 1943 copper penny (supposed to be steel).

What are the odds this guy checked for any rare pennies before putting that floor down?

Humans are not going to be taller.

The increase in average height over the past 100+ years has nothing whatsoever to do with evolution, which simply cannot operate at that speed (a handful of generations).

It has to do with nutrition. In areas where malnutrition is a major problem today, which becomes mitigated or solved in the future, average height will increase, up to a point. So will average intelligence, as it takes a lot of calories provided at regular intervals to build a brain as well as it can be for a given genotype.

A drop is about 0.05mL, so three drops is 0.15mLm, which at 3g/mL in a 95% solution is ~430mg dimethylmercury. And that's assuming 100% absorption into the skin through the glove.

The idea that what happened to her was the result of a couple drops on the back of her gloved hand is pure nonsense. She got dosed with a much higher quantity.

#6 Elemental mercury isn't that dangerous. You can swallow a spoonful and come to no harm, because it doesn't react with much of anything on the way through your body. If you spend hours breathing in the vapor over a big vat of the stuff, you'll develop problems, but there's no danger like there is with methylmercury and dimethylmercury.

And ethylmercury is mostly harmless as well, being removed quite quickly from the body. That's why it's perfectly safe to use in the vaccine preservative Thimerosal.

+8 57. Thanny commented 2 years ago on video The Nuclear Waste Problem

There's a lot wrong with this. First, Yucca Mountain has been around for quite some time, and it's only a matter of cutting through political red tape to make it an active long term facility. So the site described in the video is far from the first.

Second, radiation isn't some mysterious substance that leaks into the surroundings when given an opening. Radiation (which, in common parlance, refers specifically to ionizing radiation) is either particle emissions or gamma ray emissions. It is not contagious. If something is irradiated, it does not become radioactive.

Third, you cannot compare ancient civilizations to today's civilization. The idea that there will be some future population that doesn't know about long term nuclear storage is all but absurd. Even if something really catastrophic did happen, all records were obliterated, and future civilizations somehow didn't have the ability to detect radiation, opening a long term storage facility would not mean contaminating the surroundings. Only those who came into direct proximity of the nuclear waste would be affected.

Building more safeguards into nuclear fission plants is certainly worth doing, but scare-mongering isn't.

0 58. Thanny commented 2 years ago on video Operation: Dry Tank

Fuel pumps overheating due to low fuel is pretty much an urban legend.

Electric fuel pumps in the tank (mechanical ones are next to the engine) don't overheat from low fuel. They generally come in two types - those that need to be surrounded by fuel to radiate heat, which reside in a bucket-shaped section at the bottom of the tank that is always full of fuel, and those which are mounted at the top of the tank, and therefore almost never submerged, relying only on the fuel flowing through them to take away the heat.

Running the tank very low can run the risk of washing sediment from the bottom into the fuel system, but that's not nearly the problem it was with metal tanks (from rust).

There's no good reason to fill up more frequently. Some suggest never letting the tank get below 1/4th capacity, but that's hogwash.

Isn't this kind of thing common knowledge? My car says 0 miles left right about the time the low fuel light comes on, and that comes on when there's about 3.5 gallons of gas left. Based on my typical mileage, that means I can go for another 75 miles (~120km) or more.

It's always been the case that low fuel warning lights (and now range estimates) are set to push people towards filling up earlier rather than later. And that's such common knowledge that no one does it. Everyone getting a new car figures out how far they can really go when the low fuel indicator comes on, and bases where they stop on that. And before low fuel lights were a thing, the same scenario played out based on when the needle reached the line on the gauge marked 'E'.

0 74. Thanny commented 2 years ago on video 5 Simple Questions - Intelligence Test

So the first question was dead obvious in their intent, but it shows an abysmal failure of language comprehension on the part of the would-be quiz master.

In English, and probably most other languages, economy of words is very important. As a consequence, most statements include implicit meanings, which every fluent speaker understands, This is no different when saying things of the form "X contains Y widgets". If we mean Y or more widgets, we say "at least Y". If we mean as many as Y but no more, we say "no more than Y" or "as many as Y". If we provide no qualifications, we implicitly mean both - "X contains Y widgets" is identical in meaning to "X contains no less and no more than Y widgets".

A more concrete example is describing the number of legs an animal has. A two-legged animal does not have at least two legs. It has exactly two legs - no less, no more. A month with 28 days does not have at least 28 days, but only 28 days - no less, no more.

So the correct answer to the first question (oddly numbered #4, as if the list were a countdown) is 1 or 0 - February during normal years, and no month during leap years.

+6 106. Thanny commented 3 years ago on video Why Doesn't Time Flow Backwards?

"..the fact that we experience the flow of time right now means we're not in equilibrium."

Absolute nonsense. It will never, ever be the case that a conscious entity fails to experience the flow of time. Equilibrium, for a conscious being, is nothing more or less than a decomposing brain that has reached the point where it's a homogeneous puddle of ooze, which is capable of experiencing nothing.

Beyond the physical constraints on the ridiculous statement quoted above, there is the fact that the flow of time has nothing whatsoever to do with entropy. Reversing entropy is not equivalent with reversing time. It's equivalent with introducing energy and/or matter to a system.

The voice sounds like that of Sean Carroll, and he's made this claim (that time's arrow is a function of entropy) many times. But it's rubbish. Time is nothing more or less than a sequence of events. Entropy is the observation that absent an influx of energy, events always lead towards disorder. He's even made ridiculous statements about entropy being why we remember the past and not the future.

The very idea that the arrow of time needs and explanation is nothing but an artifact of our mathematical models of reality, which should never be confused with reality itself. The fact that you can slap a negative sign on a number representing time and do valid math with it does not indicate that in reality, the flow of time (the fact that the real-world analog of the time variable always increases) is something in need of special explanation.

InfoWars is headed by the insane Alex Jones, but PJW is not Jones. He has a conservative bent (and if you think that means he's incapable of having valid opinions, you are a dangerous ideologue), but he's not a conspiracy nut.

The only outright factual error in this video is the claim that women are stoned to death for being raped in Islamic countries. That's false. When you hear claims about women being stoned to death for being raped, what you have is a woman who claimed she was raped, to avoid the punishment for adultery (being stoned to death), and failing to convince the court of that claim. While there may have been women genuinely raped who nevertheless received the punishment for adultery, it's not correct to say the reason they were killed was the fact that they were raped. A man who rapes is stoned to death, as is a man who commits adultery. So in those situations, the man is always killed (either he committed rape or he committed adultery), while the woman can avoid punishment by convincing the court she was raped. Another instance of where Islam is painted as horrible for women, when it's actually just horrible for everyone.

Slavery was something everyone did at one point or another in history, with very few exceptions. The Europeans, after all, didn't actually go ashore to capture Africans and stuff them on a boat. They bought them from other Africans who had already enslaved them. Europeans were themselves enslaved by the Ottoman Empire for several centuries, who did unspeakable things to child abductees to turn them into Janissaries (think Unsullied in Game of Thrones, but without the castration). The US fought a bloody civil war to end slavery, which killed more Americans than any other war it's been involved in.

The overall point of the video is correct. Those people on Twitter are historically illiterate incompetents who understand nothing.

The barriers should come down about a minute before the train arrives.

The fact that the train is described as coming around a bend makes it worse - the truck driver probably looked for a train and didn't see one before deciding to proceed. He just failed to react fast enough after being no doubt startled by the barriers coming down.

#3 Guns don't create a culture of violence. That's clear from international statistics, which show no correlation between guns per capita and violence rates. And the fact that banning guns doesn't reduce homicides (Australia).

The "high" violence in the US (it's high only in comparison to a handful of first world nations with bigger social safety nets, and only on average across all states) is not caused by the guns that end up being the most used tool.

The automatic assumption that "gun violence" is caused by the presence of guns (i.e. wouldn't have taken place with another tool in the absence of guns) is irrational and unsupported by any evidence.

#4 How about from statistics? The US is a nation with around 330 million people, and, if estimates are to be believed (there are no reliable actual figures), about 300 million guns. Yet around 10 thousand people each year are killed by another person with a gun. Even if you assume that only 1 in 10 people in the US own a gun, that means 99.97% or so of gun owners are responsible enough to not kill someone with their gun each year.

The reason for the relative abundance of gun killings in the US has nothing to do with the guns themselves, which any honest person who examines all the pertinent facts would have to conclude. You can start with the relative abundance of non-gun killings (typically more than all killings combined in other first world nations), and search for an explanation of that.

Or looking down during a car ride (e.g. kids playing on a tablet rather than looking out the windows) so the motion you feel isn't backed up by what you're seeing.

+7 166. Thanny commented 4 years ago on video Premium gas vs. regular: Which is Better?

There are quite a few problems with this. First and foremost, they obviously went into filming with an expected answer, which is going to color what they decide to show.

They did not test horsepower. Put the car through a series of 0-60mph (or 0-100kph) tests with each gasoline, or use the dynamometer to actually measure the car's maximum horsepower and torque with the different fuels (which they manifestly did not do).

They did not test mileage properly. Run the engine dry with a fixed quantity of fuel at a fixed throttle several times with each fuel.

They misreported the emissions data. You can see clearly that the regular fuel had a 6.0 value with the hydrocarbon emissions, while the premium fluctuated between 6.0 and 6.1. That's a variance less than half as large as the variance in the mileage test they did do.

They also only tested a single model of car. Why not a car that actually recommends premium fuel as well? Or several different cars?

There's no data here, just one big anecdote.

And as for regular fuel octane in the US, it's actually much lower in parts of the west where elevations are a few thousand feet above sea level.

Short version of #9:

Electric car infrastructure lags well behind combustion engine infrastructure. After 100+ years of the latter and a handful of years of the former, who'd a thunk it?

Oh, and a bit about electricity generation, which ignores the trend of moving away from fossil fuels (i.e. energy stores that can only be utilized by liberating carbon into the atmosphere) and towards carbon-neutral alternatives (solar, wind, nuclear, etc.).

I'm not a huge fan of electric cars in general. I think a carbon-neutral liquid fuel system would be preferable, such as running methanol fuel cells backwards to produce combustible methyl alcohol using as inputs carbon-neutral electricity and carbon dioxide from the atmosphere, plus hydrogen cracked from water using more carbon-neutral electricity (or perhaps biological solutions involving engineered photosynthesis).

+6 179. Thanny commented 4 years ago on video The Ingenious Design of the Aluminum Beverage Can

#2 Humphry Davy, the British scientist who first identified the metallic element in the mineral alumina, first called it alumium. Then, in keeping with standard etymological conventions, he changed it to aluminum. This is in keeping with the same rules used for molybdenum, lanthanum, platinum, and tantalum. Not to mention the Latin versions of a bunch of other elements (aurum = gold, plumbum = lead, stannum = tin, and so on). The general rule was, take the metallic salt, lop off the ending 'a', then add 'um'. So zirconia became zirconium, while alumina became aluminum.

Then an etymologically deficient halfwit suggested changing it to aluminium, because most other elements ended that way, including many that weren't originally metallic salts at all. He actually wrote that "aluminum" didn't sound "classical" enough, despite being the actually correct name according to the classical system.

It wasn't until about a hundred years later that the metal became common enough for either version of the word to gain any public purchase. In America, Davy's preferred form took hold, perhaps due to being also preferred by our most famous dictionary producer, Noah Webster. In the UK, the etymologically deficient version took hold, and about 25 years ago, some international committee saw fit to choose that version, then later added that both spellings are acceptable.

So you are wrong on multiple independent levels. Congratulations.

This man is a blinkered fool. I don't want to write a novella pointing out all the factual errors in this video, which are copious. Perhaps the biggest lie is the claim that warming has levelled off in the past 17 years. It hasn't. The only way it looks remotely like it has is when you dishonestly cherry pick a sampling range that starts at an abnormal high and ends at an abnormal low, rather like comparing the temperature in mid-July to that in mid-February (for the northern hemisphere), and saying, "See? The planet's actually getting cooler."

His reasoning is far more stupid than his dishonesty. Photosynthesis operates more efficiently with more CO2. That's true. But you know what else it works better with? Water. In fact, it shuts down entirely without water, and if you raise the global temperature by increasing the amount of CO2 in the atmosphere, you create a lot more desert, where there's plenty of CO2 but no %$?#ing water. Plants are not going to thrive under those conditions.
Nor are they going to thrive when completely under water, which is where thousands of square miles of land will be if morons like him are given the time of day.

There are two meanings for the term Dark Age. One is the pejorative, indicating the the age was a period of economic and social deterioration. The other is informational, indicating that the age in question is poorly recorded (i.e. like a dark room, where you just can't see).

Used in the first sense, the modern time range is around 5th to 10th century CE. All of this guy's examples fall outside of that range, so aren't part of the Dark Ages at all. Which is no doubt largely due to the fact that however dark that age may have been in the first sense, it's certainly quite dark in the second sense.

The metal aluminum featured here is smelted from aluminum oxide (aka alumina, where the element gets its name - originally alumium, then aluminum, with some misguided folks later deciding to make it sound more like other element names as aluminium). Alumina itself has to be refined from rocks containing an amalgamation of minerals. The most common one these days is bauxite, which is typically less than half alumina.

The only chemical reaction in this video would the oxidation and whatnot of paint on the cans. The metal itself is already elemental, and undergoes nothing but a pair of phase changes - solid to liquid to solid.

This guy clearly doesn't understand evolution.

Those who didn't have the genes didn't do just fine at all - they got left behind. From the population in northern Europe, the genes spread over much of the rest of the continent (in general, the further from Sweden, the less likely you are to remain lactose tolerant).

Contrary to what this fact-challenged person claims, the people in these populations who couldn't drink milk as adults didn't do just fine at all - they were utterly out-competed, to the point where lactose tolerance in some areas approaches fixation (i.e. lactose intolerance almost completely died out).

Neutron stars are only dense as neutron stars - you need all that mass and its gravitational field to keep the neutrons packed together.

If you could magically remove a piece of a neutron star and place it somewhere else, it would promptly explode from the degeneracy pressure no longer having gravity to keep it in check. And then the neutrons would start decaying into protons, electrons, and neutrinos (neutrons don't last long outside of a nucleus), within a short time releasing 15 trillion times the energy of that biggest H bomb mentioned in the video. That's enough energy to melt all of the Earth's crust one hundred times over. That's it for all life, quite permanently. Even after the debris coalesces and re-solidifies, there won't be much in the way of water left, and there won't be any bombardment by comets to rehydrate the planet.

It's the current actually passing through the body that kills. Obviously you need a high enough voltage to get the current moving, but you can easily have a very high voltage but too low a current to do any damage. Most examples of that involve electrostatic discharge of some kind.

For tens of thousands of volts, just walk on a carpet when the air is dry, then touch a doorknob. Or find an electric fence designed to keep animals in or out. Same tens of thousands of volts, but a hell of a lot more charge. In between would be touching the outside of your car after going for a drive in the winter.

For hundreds of thousands of volts, any school room Van de Graaff generator will do. If it's big enough, you can easily get more than a million volts discharging safely into your body (or someone else's, if you hold your hand on the top for a while then point at them from about 33cm away).

One example of very high voltage with very low current that's not ESD is a taser.

Overall, however, if you see a sign warning of high voltage, you can safely assume that there's plenty of energy behind it to produce a very high current as well.

+20 248. Thanny commented 6 years ago on video How Japanese addresses work

The US does have block names, but they're not used with the mailing address. So the address 29 Main Street might be block 15, lot 41. The latter is what identifies the piece of land for legal matters, or to professionals like surveyors.

I work with data like this professionally, and I have to say that there's simply no way that using block/lot values to locate a property can be more efficient than mailing addresses. You're replacing a line labelled using sequential numbers with a polygon labelled using randomly ordered numbers. Moreover, when you're not even naming the streets, giving directions is a near impossibility, which is why Japan is littered with maps to the local blocks, and all attempts at directions require citing nearby landmarks every step of the way.

So Japanese addressing isn't just different. It's much, much worse.

Archaeologists study human cultural artifacts. Paleoanthropologists would be the ones wondering when bipedality evolved. And they conclude it happened much earlier than Homo erectus, despite what the name implies. Australopithecines, in particular, which lived in excess of 3 million years ago, had hips indicating bipedal locomotion.

The upshot is, our ancestors were bipedal long before we'd call them human (i.e. assign them to the genus Homo).

Left and right is just as parallel as up and down to the mirror. That's a nonsense explanation.

The real explanation is that mirrors do not, in fact, reverse the image from left to right. They reverse the image from front to back.

If you raise your left hand, does the reflected hand on your right go up? No, the one on your left does, because the image is *not* reversed left to right. When you look in a mirror, you get the same view you'd get if all of the object being reflected were transparent save the very surface facing the mirror. So a "reverse" word isn't really reversed - you're looking at the front surface of the letters from the back. Hold up any sufficiently light t-shirt with writing on it to a bright light, and you get the same exact view that a mirror provides, albeit with much lower fidelity due to the fabric still being in the way.

I get really tired of people using the word "chemical" as if it were synonymous with "toxin". It's abject ignorance.

Some actual facts:

1) Potassium bromate is classified as possibly causing cancer, not actually causing it. Which you can say of any oxidizing agent whatsoever. Because they oxidize. Like oxygen. That stuff we suffocate without.

2) There is no potassium bromate in the finished product. It is all consumed in the leavening, unless you add way too much. But it's already mixed in the flour in the right proportions.

Do I want it used in the making of my pizza? No, and since I don't eat at Domino's or Pizza Hut, it won't be.

But let's skip the "chemical" hysteria. And the ridiculous elitism while we're at it. Using bread flour for a more substantial crust is reducing the required skill level? Please.

There are two completely different amplifications going on here.

For the heartbeat monitoring, they're amplifying color differences to catch the subtle color changes as fresh surges of oxygenated blood flows into the capillaries and whatnot. Things other than skin will change slightly with motion, as reflections and shadows shift.

For the breathing, they're amplifying pixel displacement to exaggerate the motion - something much more complicated, as it requires first detecting which pixels are in motion. That will work better with high contrast areas, where edge detection is much simpler.

I can see some pernicious applications here as well. Those deluded into thinking polygraphs actually detect lies might be tempted to create another fraudulent device that monitors heartbeat passively using this method, and perhaps also pick up on skin moisture changes (sample the color of incoming light and model how increased reflection of that light by sweat would affect overall color - just speculation, of unknown feasibility).

MS-DOS was just a renamed 86-QDOS (Quick and Dirty Operating System), which MS licensed (and later purchased) to fulfill their contract with IBM for a 16-bit personal computer OS. It was a rough clone of CP/M (Control Program for Micros). Far from being the most important software, it was basically the minimum required to put 16-bit personal computers on the market.

Without Microsoft, the early years would likely be dominated by a 16-bit version of CP/M instead, and some other Xerox-inspired GUI for PC's instead of Windows. For a while in the mid-90's, I hoped OS/2 would remain a viable alternative, but the anti-competitive bundling practices of Microsoft ultimately consigned it to obscurity.

With MacOS always being tied to expensive Apple-only hardware (aside from a couple years in the mid-90's when they licensed clones), it was never going to dominate a market that wanted more open hardware.

The short answer to #4's question is that without Microsoft, we'd probably be better off. Windows has improved a lot over the years, but it's still lacking in a lot of fundamental areas.

There's a fairly sizable error here. While there's no convection in space, there are still two ways to lose heat - radiation and evaporation. Moisture near the surface of the skin will evaporate very quickly, giving off heat in the process (heat of vaporization, which is why we sweat). While our radiation is normally offset to a large degree by incoming radiation from our surroundings (including, to a large extent, the air around us), in the vacuum of space there's mostly just blackness. If the sun were obscured, an average man would have a net heat loss of something like 900 watts. At maybe 10 minutes to hypothermia, definitely the least troublesome problem, but it's a far cry from not freezing. You'd certainly feel cold immediately.

It's a fake. The cat isn't responding to the jump sounds at all. There's a string running under the carpet that someone is tugging on to create a ripple under the cat which prompts the jump. You can see the incriminating evidence at 1:15. It should also be fairly obvious from the fact that the cat is concentrating on the carpet, not the source of the sound.

He says "first shot", which means it's only intended to be useful for sniping. It may be able to handle movement, but not much. He also mentioned a "firing solution", which suggests that the scope has a range finder, and maybe even some kind of wind measurement, which it uses to calculate the trajectory. In other words, it does what a sniper and spotter together can do only with a lot of training and experience.

I can imagine a rich guy using it to hunt, but it seems clearly intended to make any soldier an instant sniper.

Second, I can't get over how still they hold their heads when running. That's not how it is, of course, since the neck muscles are working overtime to counteract the motion. But the result is, to my eye, astonishing. It's as if the cheetah's head is flying through the air, dragging the body behind.

+2 328. Thanny commented 7 years ago on video The moon illusion

His explanation is completely incorrect. The large moon illusion works out on the ocean, where there are no smaller objects to compare with, as well as anywhere on land where the horizon is flat and empty.

The real cause has to do with how we perceive the dome of the sky. If you poll a group of people and ask them to point to the part of the sky that's halfway up, their arms will not have an angle of 45 degrees, but something much smaller. What it indicates is that the model of the sky in our heads is that of a flattened dome, not half a sphere. Halfway up in height is not halfway to the zenith.

That makes the moon a circle on the flattened dome of the sky. When it's at the horizon, the model says it's further away. When higher up, the model says it's closer. But it subtends the same angle in both cases (we're talking about one night here, so changes in orbital distance are irrelevant), so it's subject to the Ponzo Illusion. That illusion is simply that given two objects of the same size on our retina, the one we perceive as being further away will seem larger.

+13 336. Thanny commented 7 years ago on video Aphid cloning - Battle of the Animal Sexes

It has nothing to do with variation for the species. There's no such thing as "for the good of the species" in nature. That's just a myth.

Each aphid is a machine built by aphid genes for producing more aphid genes. Mixing with other batches of aphid genes increases any one gene's odds of increasing in number, because a fresh mix of genes is more likely to be resistant to parasites. Sex versus parasitism is like changing the locks versus burglary.

The asexual reproduction phase is very much like somatic cells in a single organism replicating. Each individual aphid is unimportant, which is why you see virtually no anti-predation behavior. It's more economic to make a whole bunch more aphids than to power the intelligence required to avoid ladybugs and parasitic wasps.

Zoos are the number one way to get people to give more than two tosses about wild animals to foster support for their conservation. While the zoos of old were pretty poor places for an animal to live, modern ones give most animals quite a lot of space, as well as guaranteed nutritious meals (which no living heterotroph complains about).

Furthermore, most zoos are non-profit, and constantly struggling for funding. Despite that, they actively support wildlife conservation programs.

So if you're really interested in the well-being of animals across the globe, educate yourself about zoos, and support a quality one whenever you can.

+2 352. Thanny commented 7 years ago on video Texting and driving test

I'm too old to be a part of the mobile phone texting fad, so I can objectively say there's a bit of hysteria about it.

There have always been things in the car to dangerously distract the driver, such as reading maps, applying makeup, fetching something on the floor, etc. Texting is no more or less dangerous than any other engrossing activity. For some people, that includes a voice call (with or without headset). For others, a voice call is no more distracting than a conversation with another person in the car (again, with or without headset).

Doing anything while stopped at a light risks missing the light change, but that's it. You will not miss an emergency vehicle with a siren - that's a ridiculous claim.

I fully expect there are some people who are able to switch back and forth between phone and road rapidly enough to actually text safely, but I also expect their numbers to be so few as to suggest nothing against laws forbidding texting while actually in motion.

The percentage of dark matter and normal matter can be estimated by examining how much mass is required to produce observed results (such as galaxy rotation and gravitational lensing), and totting up how much of it is visible in any way. In that sense, it's more or less a direct measurement.

The rest, which most people call "dark energy", is a number spit out of cosmological models that need to account for the apparent accelerating expansion of the universe. You can calculate how much energy is required to drive the observed acceleration. And since matter and energy are interchangeable, you can combine the quantities to provide a total, from which you get the percentages.

Other things will heat up as well, including dishes that are not microwave safe (that's what makes them unsafe - they absorb the microwaves and heat up by themselves, unlike safe dishes which get hot only by virtue of contact with the heated food).

+1 397. Thanny commented 8 years ago on video What if every machine would run with gasoline?

The greenhouse effect is an indisputable fact of chemistry. Carbon dioxide is a greenhouse gas. Increase the amount of carbon dioxide in the atmosphere, and you increase the temperature of the planet.

#20 has no clue about anything he/she wrote. With no greenhouse effect, the planet Venus would be slightly below the freezing point of water, simply because of its distance from the sun. But Venus has a huge amount of carbon dioxide in its atmosphere, and the actual temperature is above the melting point of lead.

Beyond that, it's worth pointing out that burning fuel is not a problem for the carbon dioxide balance. It's only burning fossil fuels that's a problem, since that releases carbon that had been sequestered in the ground. Anything else you burn will be releasing only carbon that was removed from the atmosphere during its creation.

So using electricity from solar and wind farms to crack water for hydrogen and drive methanol fuel cells backwards would provide a liquid fuel that be burned without impacting the carbon balance. The CO2 released was all taken from the atmosphere during production, so it's a zero net change.

+3 404. Thanny commented 8 years ago on video The Pale Blue Dot

#7 The habitability of Earth is not nearly as fragile as you suggest. Ozone blocks ultraviolet radiation. It does not have any large effect on temperature, and it fluctuates in thickness constantly. It didn't exist at all until well after life evolved, since free oxygen (from which ozone is constantly created) did not exist before it was created by life. Our distance to the sun varies throughout the orbit as well. Changing axial tilt would make seasons more or less severe at certain latitudes, but not affect overall habitability.

Furthermore, a megaparsec is not a million light years. It's a million parsecs. A parsec is the distance at which 1 AU (the distance from Earth to Sol) would subtend an angle of one arcsecond. When you do the math, you get 3.262 light years.

All these facts are accessible to anyone who pays attention in high school science classes.

There is no such thing as a safe following distance for this kind of incident.

I once had an aluminum drive shaft of some kind get kicked up by a car and crash into my windshield. It was caught between the hood and fender, otherwise one of the two people in the front seat would have been hit, probably fatally. The car was quite far ahead, and there's no way the driver (not me - I was dozing in the passenger seat, and my reaction was a loud WTF) would have been able to avoid it.

In cases like these, the responsibility lies with the vehicle that hits the debris. Something like that is easily seen in the road, and neglecting to avoid it establishes liability. My insurance company went after that of the person who launched the drive shaft at my car, and got paid for most of the damages.

The elk go there because of the grass created by settlement. It's not an elk gathering area that was invaded by humans.

This notion that animals have always been wherever we currently find them is just ludicrous. They move around just as much as we do, and "invade" just as rudely, from the perspective of whatever critters happen to be there at the time.

Know where else elk like to hang out in great numbers these days? In the valley that 31 years ago was plowed clear of every living thing by a mud and ash flow from Mt. St. Helens in Washington State, USA. They wouldn't be there before the eruption, just as these elk wouldn't be in that town before the well-manicured grassland created by human habitation.

Early 20th century anthropologists were deceptive in their reports, and also deceived by the natives they studied. These people do not live idyllic lives, free from the worries of modern civilization. Hobbes had it mostly right when he wrote, of pre-civilized human life, that it was "nasty, brutish, and short".

Beyond that, there's also an island south of India populated by hostile natives with no exposure to modern civilization, beyond the boats off shore that they throw spears and whatnot at.

Advocating the continued isolation of these people's is a deeply selfish act, on the whole, though it's arguable that becoming another poor underclass in a developing nation would not be much of an improvement at this time.

#3 It's not our fault. Almost all of us take foreign language classes in high school (also, Ich kann ein bisschen Deutsch), but there's no pressure in society to master anything but English. There's Spanish to the south (and a lot more Americans who live near the border speak it), but nothing but English elsewhere on the continent. Most of our entertainment imports are either from the UK, or English-language remakes. The occasional non-English movie that gains popularity gets by fine with subtitles.

It certainly doesn't help that someone competent in English is never more than a stone's throw away whenever one travels.

The simple fact is, most people who speak more than one language speak their native language and English, which is the de facto international language (and the official language of science). The Korean and German men weren't conversing in German or Korean, after all. The only language they shared a fluency in was English. So it's rather unfair to say that native English speakers only know one language, when there's no other language one has an incentive to learn, outside of some specific circumstance.

People in the UK aren't any better, despite being in proximity to a host of other languages, because they already know the one language they can expect to be understood almost anywhere.

+5 442. Thanny commented 9 years ago on video Particles

This is deeply misleading.

Observations don't take place with a little eyeball that magically detects an electron without interfering with it. All observations involve meddling of some sort - either you capture the result of something that was already happening (such as a photon being emitted by or bouncing off of an object), or you cause an impact of some sort to capture an effect. In all cases, the observed object behaves differently because of what happened to allow the observation - the observation itself is irrelevant.

In the case of the double-slit experiment, the only way to detect the electron is to put something in the way of it that it interacts with in some way to produce something measurable (an electrical impulse, say, or an emitted photon). It will not continue on to do exactly what it was going to do before the "observation" (a word that is treated as passive in common parlance, but which is anything but in the world of particle physics).

#9 Daily disposables are a much thinner lens, and would not last months, no matter how well you cared for them.

Longer-lasting lenses (called "frequent replacement", as "disposables" technically applies to the dailies) are thicker and more durable, though I can't say how they actually compare to the non-disposable ones. I don't know how well frequent replacement lenses would hold up to protein removal. I do know that after three or four weeks, I can tell that my lenses need to be replaced, which would translate into an enzyme soak otherwise. I can't imagine using a single pair for months on end.

One notable difference between the disposable or frequent replacement lenses would be customization. As shown in this video, you can have a pair cut to your exact eye measurements. The others come in one or a few base curve sizes and 0.25 diopter increments. Those designed for astigmatism don't start until 0.75 diopters of cylinder, and the angles come in ten degree increments.

The gyro holders are on the right, a button-pressing rig is in the center, and the spin-up motor is on the left. You instruct the robot to move the gyros to the motor, then to one of two indented buttons, connected by a lever to a bracket holding a normal NES controller.

The only game I had that was designed for the robot was the one that came with it - Gyromite. Holding buttons down kept certain gates or walls open, and the challenge was to keep the gyros spun up and on the right buttons.

Several comments don't seem to understand the concept of efficiency. When something is said to be, say, 80% efficient, that means 80% of the energy going into it is used for some kind of work. What happens to the other 20%? It's given off as waste heat.

When the task itself is giving off heat, efficiency is not in the mix, save for one aspect - putting as much of the heat as possible where you want it, instead of into the outside world where it can't do work.

Once you insulate as much as is possible, all you're left with is the need for the fixed quantity of heat required to melt and vaporize a given mass. There's no more room for increased efficiency.

The simple fact is, this device is useless for reducing carbon dioxide. It's utility is solely in managing solid plastic waste. Much better to simply recycle the plastic into more plastic - less energy input, and the carbon remains fixed.

#10 Refueling time is definitely an issue to be concerned with, which is why I generally favor doing something like using methanol to power conventional engines, with the methanol produced in a carbon-neutral fashion (such as running a fuel cell backwards with hydrogen and electricity provided by clean generation).

However, work is being done on battery charging speed. At least one researcher I've heard about has materials which allow charging fully in seconds. A full electric car battery might take a couple minutes.

But the fact is that a commuter could easily benefit from an electric car with this range, as the car won't need to be charged quickly, or even away from home. Granted, a Tesla Roadster is for a wealthy commuter. The company made a deliberate choice to start with a sports car, probably to attack the idea that an electric car has to be a tiny powerless roller skate. I think it does that rather effectively.

Has to be fake. There's no way someone as drunk as the cop appeared to be at the beginning could run without falling.

Not bad for an animal with no brain.

I felt compelled to clear my own throat listening to that.

Organic food is not more healthful. It does not taste better. It is not safer. But it's definitely more expensive.

If that's not enough, anyone who would want the entire world to eat only organic food would need to begin by creating a list of the two billion people doomed to immediate starvation.

Clearly someone does not understand the concept of mimicry in evolution. It has nothing to do with conscious imitation, and everything to do with differential reproduction of inherited appearances and behaviors over vast spans of time.

Too bad no one responsible for this "report" understood thermodynamics, else they'd know that the energy produced by the combustion would always be less than the energy put into cracking the water.

The blatant quackery about the cancer was worse, because people might try that absolute nonsense and die instead of getting proper treatment.

That's a dust devil, not a tornado. Pretty impressive one, though.

It's "dadgummit", which is an old substitute for "god damn it", from when people took such things seriously.

It's like "dagnabbit", for the same phrase, or "tarnation" instead of "damnation".

There's a great many such words and phrases which I imagine most second-language English speakers just aren't aware of. Watching old Warner Brothers cartoons is a good way to encounter a bunch of them, especially Yosemite Sam.

+4 494. Thanny commented 9 years ago on video Remarkable space saving furniture.

Confused by English measurements, and wondering why we in the US don't use the metric system? It's because measurement systems different from what you grow up in are confusing. You've developed an intuitive sense for measurements in centimeters and degrees Celsius. We've developed an intuitive sense for inches and degrees Fahrenheit. Speeds in miles per hour are familiar to us. Speeds in kilometers per hour always sound faster than they are, just as (I expect) speeds in the former metric sound slower to you than they really are.

So it's just momentum that keeps us on English units, and I don't really know what it would take to change that. Passing a law mandating the metric system in some way would be exceedingly difficult.

He didn't hold the camera at all, much less steadily. He was obviously using this:

The camera is attached to his arm, pointing towards his body on the same axis. So if his arm remains extended and attached to his torso, the camera has no choice but to stay centered on his body, which is the only frame of reference which appears relatively steady.

+3 496. Thanny commented 9 years ago on video Cool solution to clean up oil disaster

While 62,500 tons of hay might seem like a lot, Louisiana by itself produced 1.1 million tons of hay in 2009.

That's less than one percent of the national total (146 million tons in 2008).

So, supplying that much hay is not a problem. Collecting it would be more difficult, but I expect it's a whole lot easier to search for and collect oily hay on the surface than oil itself. As stated in the video, collecting it from beaches is a lot easier than collecting the oil itself.

The only concern I have about this method is that the floating hay may attract marine animals, which would otherwise have stayed away from the oil.

Just go to the YouTube link in comment #10. It's explained pretty clearly exactly how the trick works in that video's description. It does not involve any confederates.

+8 498. Thanny commented 9 years ago on video Only energy source is the wind and the sun.

It's a glider. It has no power source. Solar heating will cause updrafts that give it a bit of lift. Headwinds will provide lift as well, but drain forward momentum.

The bulk of the energy, however, was provided in advance by the engine of the tow plane that pulled him off the ground and up the mountain, in the process stored as gravitational potential energy, which was then expended by the glider as it made its way back down the mountain.

+9 499. Thanny commented 9 years ago on video Big Spider

All spiders are venomous. It's just a matter of how potent the venom is. A Redback, close cousin to the Black Widow, will produce a very painful bite, but almost never a fatal one.

This guy was not thinking too intelligently. Even if he did manage to get the container around the spider, what was he going to do next? The spider would just climb right out if he brought it down from the ceiling, and I saw no evidence of a lid nearby.

Lots of "push" mowers have drive wheels. These days, in fact, it's only the cheaper models that don't.

And anyone who thinks this is the result of laziness has no conception of how much effort making this video would take.

+5 502. Thanny commented 9 years ago on video Rotifers - Just add water!

The really interesting thing about Bdelloid Rotifers is that they are asexual, and have been for millions of years.

Normally, when a species drops sex, it goes extinct after a short while, for a number of reasons centered on a lack of genetic diversity.

It seems the rotifers escape this fate much like bacteria do - taking genes from the environment to try on for size.

I've seen elsewhere, too, that their little drying-up trick helps them combat a particularly pernicious fungus. After a couple weeks without water, the rotifers remain viable, but the fungus dies completely. Without that trick, the fungus is almost 100% fatal.
