Try reading rather than feeling your self-entitled conservative outrage against invented hypocrisy to excuse actual hypocrisy.

Well, I'm glad that you're finally trying. However, you still have problems of non-applicability, and have introduced spherical cow problems. To be blunt, in theory, there's no difference between theory and reality. In reality there is. Oh, and I'm quite up on my physics, and they don't say that I'm wrong. I may not be an EE, but I'm still STEM. So you can drop the credentials fallacy.

Next, I'll point out that you're strawmanning my(and my cited article)on the actual efficiency. The article, and I, have at most said "as efficient or possibly more". You immediately dropped the "as efficient" to argue against more efficient. To meet "possibly more", all you'd need to do is find a fairly inefficient corded charger. A cheap one, not properly optimized for efficiency.

All I've been arguing is "as efficient".

Still, you might want to read your links to make sure they say what you mean. For example, your first link says this:

But, ferromagnetic materials like steel as core of transformer, suffers from hysteresis loss, eddy current losses. Also it faces problem of getting saturated after certain level of magnetization. But these can be avoided in air core transformer as ferromagnetic core is absent in this transformer.

Looks to me like they're saying the opposite of what you're asserting. In specific circumstances, air core transformers can be more efficient than steel core. Thank you for providing more proof for my position.

Second link, continuing on from slide 5, at slide 8 they mention that increasing the dimensions of the transformer increases the coupling factor, and I can clearly see the charts showing a factor above 0.95, where 1 would be a theoretical ideal coupler ratio.

Given that one of the points I've made is that inefficiency is noted on the wiki page for under 100 watt applications, presumably with a coil around an inch across, while EV class induction coils bust the 5kW where it isn't a problem anymore, and are closer to a couple feet...

So congratulations, citation 2 also supports that a nice large open core induction coil can realistically be efficient enough for the cited charger efficiencies. You'd almost think that the businesses designing them put engineering work in.

Still, let's look at what wikipedia says about magnetic cores.

In some cases the losses are undesirable and with very strong fields saturation can be a problem, and an 'air core' is used. A former may still be used; a piece of material, such as plastic or a composite, that may not have any significant magnetic permeability but which simply holds the coils of wires in place.

What is this in reference to? Losses from eddy currents, hysteresis, and high field strengths causing saturation. What might we be seeing at 5kW and up? Why might we NOT want losses?Sounds like a potential application for an air core to me.

Citation 3 is really irrelevant. It isn't even a good explanation of coupling factor for laymen.

Noticeably lacking from your citations is that iron core is always better than air core.

Also, I reject your contention of misaligned coils, as quite a lot of development work was done to prevent that little problem.

SAE International -93% efficiency, grid to battery.

Notice that I'm posting, not theoretical stuff, but actual produced hardware, documentation about inductive EV chargers, not theoretical stuff.

Oh, and I just noticed. You're attacking a strawman. I didn't say that an air core transformer is more efficient than steel core. If that was true, we wouldn't use steel cores. Though some of that is about cost too. I'm looking

Then don't use the word statistical significance to express the word "real". This "p value exaggerate" has been discussed over 10 years ago, but the p-value is still being used because many people, like you, are, as you are saying, have to accept some thing or method in order to be "real". As MightyMartian said, p-value could be used in initial test, but it should never be used as "statistical significance" at all.

Even in Newton's theory of gravity, photons are deflected from the Sun. Interesting, even some Physicists forget this! However there is a difference of a factor of 2 between the predictions of Newton's theory of gravity and Einstein's general relativity, in the amount of the affect.

https://briankoberlein.com/201...

The catch is that the amount of bending predicted by Newton’s model is half what Einstein’s model predicted. Eddington actually demonstrated not only that light was gravitationally deflected, but that the amount matched Einstein, and not Newton.

Newton Gravity can be manipulated to give an approximation of bending light, but was not done in advance of Einstein GR. So it is just an exercise with approximate results.
Local gravity acceleration does not depend on the small mass of a falling object, only the mass of the sun or other large body. Then curvature is implied.
g = MG/r2
Radial velocity changes according to curvature
dvr/dt = g
  Taken into the usual hyperbolic geometry, it leads to an answer for bending of light that is only half as large as GR and the accepted observations

The cradle to grave environmental impact of most lithium-ion batteries is small, especially if CO2 is your primary concern. See for example https://www.researchgate.net/publication/231269141_Batteries_from_Cradle_to_Grave. See also Bingbing Li, Jianyang Li, Chris Yuan's "Life Cycle Assessment of Lithium Ion Batteries with Silicon Nanowire Anode for Electric Vehicles" (which can be found easily online but which I can't link to because the Slashdot filter is unhappy with the very long URL). That's specifically for silicon nanowire anode batteries, which is a pretty common design. The numbers for most others aren't that far off. Note also that as battery recycling and reuse becomes more common, and economies of scale ramp up further, the footprints in terms of CO2 and other pollutants will continue to decline.

This also doesn't make much sense as an issue in the context of Toyota since a hybrid requires a pretty decent size battery also. While previous batteries were nickel-metal hydride for the Prius, the newer ones use a hefty lithium ion battery also. https://www.greencarreports.com/news/1120320_lithium-ion-vs-nickel-metal-hydride-toyota-still-likes-both-for-its-hybrids. If one thinks that batteries are a big problem, then it isn't clear why one would think hybrid cars are a good thing.

Quite a lot of detail here. He also includes calculations for required levels of spray to achieve the desired albedo increase, methods for assigning vessels to the areas with the highest effect, etc.

I found a paper on an ultrasonic fingerprint sensor: https://www.researchgate.net/p... . It's probrably not the exact technology that qualcomm uses (this one doesn't handle 2 mm of display and touch screen on top of the sensor). But it does mention an essential concept: the sensor is an array of transducers; a cluster of nearby transducers sends an ultrasonic pulse (14 MHz carrier, ) with delays such that the wave is focused at some distance from the transducer, somewhere inside the skin (so that it's harder to fake).

Presumably, one could do many pixels in parallel, if there is enough data bandwidth and signal processing capacity to handle entire waveforms for each pixel.

As someone that wrote an IEEE paper literally on energy trade-offs on computation versus communication, and presented it at an international conference, this BBC article is a bunch of hype.

This argument assumes that streaming is always streamed, from a server someplace else. ANY time there is ANY kind of offline ability to listen, that file has been cached locally.

This article is by a subset of the authors and seems to be about the same molecules.

Chamber pressure is correlated to both thrust (higher chamber pressure = higher mass flow rate) and efficiency (and thus ISP, see here).

AFAIK, thrust density is the more key factor here, at least for Super Heavy (the first stage). There's a sort of "maximum height" to a rocket stage which relates to the thrust density. Your ability to pack more engines into the rocket corresponds to the rocket's cross section at the base. These engines in turn have to lift a column of liquid sitting above them; each engine can be viewed as having to lift the portion of the column of liquid directly above it (in addition to dead mass and payload). Eventually you get to a height where the mass of liquid (plus overhead) above each engine equals the thrust, and you don't move at all. The higher the thrust density of your engines, the taller you can realistically make that stage, the more fuel it can carry, and - for a given ratio of lower stage mass to upper stage mass - the heavier the payload it can launch (for a given dV). Other options to increase rocket upper stage masses come with disadvantages, such as making the rocket higher diameter (more air resistance) or adding strap-on boosters (more air resistance, more complexity, more work in recovery for reuse).

Thrust density is primarily of importance for lower stages (which is why you don't see many hydrolox lower stages without boosters), and why strap-on boosters (incl. very high thrust density solid rocket boosters) are commonly added to the first stages of large rockets. Thrust density limits are also why small rockets tend to be shaped like pencils (very high aspect ratio) while large rockets tend to be fatter, particularly at the base. For upper stages, ISP is of greater importance.

Also, for a rocket of a given (constant) height, improving its engines' thrust density comes with another advantage: they burn through their fuel faster and deliver the stage's dV faster. While there are limits to how fast you want to do this in the lower atmosphere, once you're past max-Q, more thrust is better (up to the G-force limits of your payload/passengers), as it means lower gravity losses.

Excellent post. I will add, in addition, that land use was also responsible for the coldest period of the Little Ice Age, when CO2 levels plunged from about 1550 to 1610, and then started to recover.

What happened to CO2 levels between 1550 and 1610? Well, starting in 1539 Hernando de Soto, starting with 660 men (carrying typhus, measles, and small pox) began to explore North America. De Soto encountered dense settlements along the Gulf Coast, and rivers of the South East. The next group of explorers found those same areas thinly populated.

It appears that the diseases spread by De Soto and his men started a wave of pandemic sweeping across the densely settled section of North America, killing perhaps 90% of the inhabitants. This meant that the large areas of the continent that had been under agricultural or horticultural care by Indians (large areas were cleared by burning at regular intervals for example) began to regrow forests, and lock up CO2 on a huge scale.

BTW, the hordes of Passenger Pigeons observed by later European observers appear to be a result of this same event. They genetic analysis indicates an enormous population explosion around 1600. Apparently all the now untended nut trees used for food by Indians served as windfall for the pigeons leading to a previously uncommon species to dominate, for awhile.

I am sorry that you felt attacked. An extra month of risk is minor in the grand scheme of things.

However, vaccine timing is a very well studied field since there is lots of data. So immunologists have plenty of data to know when and how serious adverse reactions can occur. In fact, there is an entire reporting system for vaccine reactions: VAERS

With that data, doctors can know when it's unsafe to give vaccines. Such as this chart from the CDC with contraindications and precautions of when not to vaccinate. Even further here's a peer reviewed paper on the topic

I thought the same, but then I looked at the numbers. A Mooney M20 has a skin thickness of 0.025" at the tip increasing to 0.04" at the inner 50% of the wing*. The skin thickness of an A340 at the leading edge slats is 1mm (2mm for an A320)**. 0.04" is 1.0.16mm, so the thickness is about right (the video shows the impact where the thickness to chord ratio is fairly high, which suggests near the root).

Leading edge curvature may also effect the results. A relatively thin wing will have a higher curvature which tends to be stronger than a thicker wing.

Another factor is the damage caused to the systems. The damage caused to the M20 will cause airflow to separate early, so the area behind the impact is unlikely to generate much lift. That's obviously bad. For a commercial aircraft, you're also damaging the slats which are generating a significant amount of extra lift (assuming the impact is at low level), as well as reducing the lift along the wing. Of course, the larger the wing, the smaller the percentage of lift lost due to damage will be.

No, it's not. Also, in a metalanguage, you're not limited in for what target environments you can write code. There's no reason you couldn't write DSP code in it if you wanted. Found this in ten seconds, for example. Likewise, there have been Lisp-based hardware definition languages. There's no specific semantics imposed on all your code, which is what makes all this possible - you can define your own semantics for parts or the whole of your code if you decide that the value of this is greater than the effort expended.

Fission reactors can't suffer nuclear detonation either ... Chernobyl suffered a thermal explosion.

Scientists might disagree

That's not what that paper says. The paper says the scientists agree with the GP. I know that paper is dense physics and statistics but nowhere in that paper did it say there was a nuclear detonation. Not a single word. Is this what passes for thought in society now?

Yeah, not even close to full throttle. More like 60% at cruise for a jet, and then as low as they will go while still running for descent.

The electrics would have the advantage of being at zero (or even recovering charge) during descent.

I'm not actually that much of a Mars advocate, and think the simplicity of using water there is overplayed (people talk about it like it's some sort of pure snow that you just pick up and melt, but it's (mostly) a rock-hard toxic brine mixed with sand and clay) - but come on, if you're going to talk about something, learn the basics.

Real question: is "how the fuck is this actually better than biometrics?" Biometrics are relatively difficult to clone or spoof. A chip is just an ID card implanted in a person -- it can be cloned or otherwise spoofed more easily than the alternative.

Your information is out of date. The first generation of passive RFID chips were nothing more than that, a bar code in digital form. However passive chips aren't actually passive in a computing sense, they're just powered by the radio signal so the available power is very low. So they started making more complex challenge-response systems, some of which was snake oil but now they've found ways to do it with proper cryptographic primitives.

For example here's a paper about using ECC verification of authentic bank notes. Here's AES encryption for storage and Keccak hashing. They make the tags considerably more complex and costly with greatly reduced range but for finger/card on scanner distances we can now make passive tokens as secure as active ones. What hasn't really materialized yet is a dominant cryptographic standard, though EPC Gen2v2 has the framework for it in the communications protocol.

What also hasn't really materialized yet is any standard system for unrelated parties to share a chip, apart from the simple identification tag were they can get your serial number and put it into their system. The chips are very much still designed around having one company picking features and programming them, not the user gathering stuff from many companies on their personal chip. I suppose we will get there, but this is still very much a moving target.

As alpha particles coming from the sun the regolith of the moon should be full of helium 3. However, the fusion we are attempting here relies on D-T fusion. Any fusion attempts with He3 will require much much higher temperatures - the nuclear cross-sections are much smaller. See graph here:

https://www.researchgate.net/f...

Even if technically possible it wouldn't be economically for a long time, if ever. If a reactor can increase to these much higher energies boron proton fusion is also a possibility, and much cheaper (tri-alpha in CA is attempting this).

Stone dust, the remains from rock crushing for gravel, has already been tested for concrete. It works fine:

I'm gonna go out on a limb here and claim that this is a product of bias and mental issues by the authors.
Much like how the authors of SuperFreakonomics couldn't have resisted their "one clever trick to fix global warming" chapter thanks to their personal biases. Which came back to bite them.
Also, the claim made in the paper is clearly false, even fraudulent.
Whether due to bias or to drum up publicity, I don't know. But they actually show that they are wrong.
More on that below. First a word or two on authors.

David W.Keith is a pusher of solar and geoengineering as a solution for climate change.
Also, best way to solve that climate change, according to him, is to start spraying sulfuric acid into air.
And he owns and runs a geoengineering company.
Which kinda runs on tar sands money.

Carbon Engineering is funded by several government and sustainability-focused agencies as well as by private investors, including Microsoft founder Bill Gates and oil sands financier N. Murray Edwards.[5][6][7]

Lee Miller on the other hand really hates them windmills.
And both windmills and photovoltaics should be kept out of the cities, tucked away somewhere in the desert.

In fact, he's done resear... I mean he played with computer models to "prove" that installing windmills will basically... stop the wind. Well... slow it down.
Someone should have told him about all those sails we used to use globally, that we're no longer using.

I.e. That a reduction of things to preindustrial levels actually requires reduction of wind speeds as well.
Or remind him that the air moved by the wind is a fluid. Like water.
And just like how water in the sea doesn't stop moving because of all the boats blocking it from moving freely... neither will global air currents actually slow down.
And even if they do - we could just reduce the number of flags and start driving cars only downwind, while wearing more tight fitting clothes, right?
Or tell him about the chance that his model is NOT REALLY a completely accurate representation of reality.

As for the study... It claims the following:

generating today's US electricity demand (0.5 TWe) with wind power would warm Continental US surface temperatures by 0.24 C.
...
The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind.

It also claims that solar effect would be smaller but that's besides the point, unless you're looking for more bias fodder.

The issue is that those "approximately equivalent" and "large compared with the reduced warming achieved by decarbonizing US electricity" are COMPLETELY ignoring that the US is a part of a global system.
As seen from the graph they've provided.

They claim a warming of 0.24C over Continental US from 0.5TWe produced with wind power, by 2080, at which point it would level out.
At the same time they claim a cooling of about -0.48C over Continental US from

The so called "study" is a study only in piggybacking on sensationalism and stirring up division.
Author, one "Morten Bay, Ph.D., Research Fellow, Center for the Digital Future USC Annenberg School for Communication and Journalism" is himself, functionally, a troII.
Whether he is also intentionally peddling and hyping fraudulent studies to increase his media exposure or is just a victim of his own incompetence... that's up to debate.
But let's just say that he didn't pick a less popular franchise for his "study".

Anyway...
The Fraudulent Study found following...

Examining 967 tweets (that's TWEETS - not accounts), made "between December 13, 2017 and July 20, 2018." on a platform where around 6000 tweets are made each second, "206 expressed a negative sentiment towards the film and its director, which is 21.9% or a little more than one in five fans."
Out of those 206... "Using the Botometer mentioned in the Method section, 11 out of the of 206 accounts expressing negative sentiments were identified as bots."
But that's not all!
Our boy Morten also claims that through his spider senses he "identified 33 of the 206 negative accounts as troIIs and/or sock puppets."
Out of those 33 trolls and socks...

16 of these 33 troII/sock puppet accounts appear to be Russian trolls, or at least possess several of the Russian troII characteristics presented above.

Anyway... author claims he looked through some 967 tweets aimed at Rian Johnson, over a period of 6 months, finding 11 tweets made by probable bots, and 16 he thinks may be Russian.
Cause their language skills were poor, their names were generic and they had no profile photos.

7 of the 16 had auto-generated handles consisting of a very common, English name followed by a series of seemingly random digits, and five of those seven had not uploaded a profile image, a combination which according to the studies mentioned above, is a typical characteristic of Russian troII accounts.

Out of those 16, 4(?) were actually identified as Russian troIIs.
@1popculturefan, @MarcoSo94862885, @VPalmera and @ThatNikkaGeeked.
Also, there is another account retweeting @1popculturefan which is, maybe, also a Russian troll/sock.

It doesn't help that the author keeps interchangeably referring to tweets as accounts.
Or that there is no summary of tweets or accounts.
Thus one can't tell if he's referring to some of the same accounts (or tweets) when he says that "6 of the 16 accounts have an extremely high retweet rate" and "9 accounts have been through the "resets"" while "4 accounts present themselves as a type of news source".
Are those 6 among the 9? 4 among 6? Who knows!

On a side note, TIL that using the word "troII" more than a certain number of times in the text activates Slashdot lameness filter.
Luckily, bitches don't know about my upper case i.

Oh, and the movie did suck.

She was asked for a quote, not a dissertation. There are decades of papers and studies in this area if you want to read up about it.

This is James Damore all over again. The studies cited don't say what he thinks they say. The classic example is this one, which a naive reader might conclude proves that there is a difference between men and women that could account for the imbalance in STEM... Except that the differences are far too small to draw that conclusion.

This is called the "incoherence problem", where otherwise smart people bring together a bunch of overlapping data and reach unwarranted conclusions by building it into a nonsensical framework.

Exactly Nancy,

It seems like Chris is a victim here. He keeps on reading those SEO, youtube algorithm, basically get rich quick sites. He doesn't realize that he is the fish for them since they make money off him with their own schemes. Then, he wastes his time trying to implement what those sites suggest and he ends up disturbing people.

I mean, those crooks tell Chris that he has to build personal brands and he goes on the Internet and makes everything about himself public!

I believe we should bring this up at our next meeting. He might not be our only patient victim of such on-line abuse.
