You can't say that!!!

That may be sort of true for traditional solar panels. There is scant data on whether a solar roof will ever be cost-effective. They are an unproven technology at this point.

There are several differences between solar panels and solar roofs:

1) Solar roof is more expensive and less efficient. You're trading efficiency for something that looks nice. Is that something a government should subsidize? Rich people getting subsidies for aesthetic reasons?

2) Solar roof panels are not as durable as solar panels, are not as scalable, and the market for them is tiny - limited to people who want to get solar panels and a new roof. V1 and V2 versions of Tesla roof was a disaster.

3) Installation is much much harder and requires specialized professionals. Installing solar panels is already fraught with challenges (safety and otherwise), and all those need to do is collect sunshine. A solar roof also needs to take into account protection from the elements and therefore needs increased durability.

Based on what? Empirical experience with macroscopic objects? There are tons of phenomenons that are at odds with everyday empirical experience for that to matter (relativity has all kinds of such cases).

I think there are a couple of relevant factors

- Can be distributed as a single binary, not requiring an interpreter and virtual environment.
- Being more fun to make a hobby tool in due to minimal footguns compared to C/C++.
- Really good dependency management and build tool making it easy to compose these CLIs out of powerful building blocks (at east for Rust). For example, ripgrep is broken up into a lot of packages that you can compose together to make your own custom tool.
An observation: I have always taken the meaning of the word "illustrated" to specifically refer to non-lexical graphics. Searching the dictionary definition of the word, I find a looser definition that applies to "examples" intended to aid an explanation.

This is a similar cognitive dissonance to when I first learned that "Visual Basic" and "Visual Studio" meant that the syntax of the displayed code was highlighted, not graphically represented in a non-lexical way.

Physicist here. This is just self-congratulatory nonsense. Though I shouldn't be surprised, because I originally signed up for this site to comment against some other self-congratulatory nonsense.

Quantum mechanics is built on extraordinarily simple rules, in fact simpler ones than classical mechanics: all you do is sum up the amplitudes for various paths, and square it to get a probability. The problem is that the objects obeying these rules thus act neither like particles nor waves. So obsessing over whether quantum objects are "really" particles or waves is not useful.

It certainly works sometimes. There are many limits where quantum objects behave just like particles, or just like waves (there must be, since we must be able to recover classical mechanics from quantum mechanics). And sometimes you can describe a quantum calculation in terms of classical wave or particle intuition, which is what's going on here. The double slit experiment is in fact so simple that I know of at least 5 ways to derive the result, using all sorts of different intuition. "Duane's law" is one of them, though I never knew it had a name, as it pops out rather straightforwardly from the mathematics.

The reason that we don't try to extend this to cover all of quantum mechanics is because it doesn't work. Treating the quantum mechanics as if it were classical underneath leads to all kinds of paradoxes. Bell inequality violations tell us that the classical variables would have to either influence each other faster than light, or be pre-set since the beginning of the universe in a malicious conspiracy. The delayed choice quantum eraser tells us that if you want to treat the photon as a classical particle, you need to accept that it can retroactively change the past. Yet another failed attempt is quantum logic: if you insist on treating quantum superpositions as representing some unknown classical position of a particle, you need propositions about those positions to violate the rules of logic themselves.

Hundreds of experiments probing quantum mechanics have been performed, all with the same results: committing to a classical ontology in terms of "waves" or "particles" costs you more than just accepting that quantum objects are different from either.

Physicists have spent a lot of energy thinking about this. All of the author's claims were under active debate in the 1920s. He is just completely ignoring the following century of investigation, and claiming that it never happened!

The same way a logical argument or a mathematical proof can demonstrate anything.

It just can't prove it empirically -- but it can very well demonstrate it.

Your question is also a "though experiment" (it's pure thought) and yet you aim it to demonstrate something.
Which happens, and it's a very bad practice if things are not transparent.

I actually don't like the double slit experiment because it's so easy to confuse yourself. Good for learning the math, maybe, but bad for presenting the "weirdness." Tests of Bell's inequalities are much more interesting and IMO cut straight to the heart of the weirdness of QM. Likewise with tests of the quantum Zeno effect. For me, at least, these two experiments go straight to "okay fine, measurement is weird and let's just treat superposition as its own thing" while double slit experiments beg for hand waving mysticism.

The sad thing is, the feed-in tariff subsidy would be less than UK's existing fossil fuel subsidies for homeowners. Yet solar is worth doing today in the UK, even with no subsidy if you project to stay in the house long enough to pay back capital cost.

With current solar pricing, it would be better for everyone if they simply moved a requirement for solar into the building regs. Like they've steadily done with insulation levels- though these are not yet adequate.
man in this case his intentions are crystal clear. he hired a hitman for a giant sum in his country. there is no ambiguity at all about his intentions
Once you've hired a hitman, the outcome is basically out of your control. Is there an argument where someone had hired a hitman with the intent they're unsuccessful? That seems far fetched to me.

I can buy your argument if they had intended to commit the murder themselves, because they can change their mind at any point up to actually doing it.

Similar situations to the hitman exist, too: planting a bomb, poisoning food, etc. Just because they're a bad bomb maker, or the poison wasn't potent enough, or the target doesn't drive/eat the food/etc doesn't change that they clearly intended to kill someone. To be clear, I draw a distinct line between possessing a bomb and actually planting it in someone's car - the former might be still be a crime but is clearly not the same severity as actually killing someone, whereas the actions the perpetrator took in the latter are indistinguishable, regardless of outcome.

No no. That's not how it works. Rich people have money, so they are perfect early adopters since they subsidize new technology until the technology gains economies of scale. But that's the key thing, they are using their own money to do that. It's not the same when you have the government subsidize their purchase.
>The focus on “observation” in quantum mechanics is dumb and damaging. In quantum mechanics observation means something very different from what people assume when you use the word observation.

Which is still neither here nor there concerning this case.

Even with the different meaning of observation from "people assume when you use the word observation", Duane’s law still doesn't explain the outcome.

Thanks for reporting back about what is discussed in the rest of the article. I still think the author is confused about two different things: popularity and centralisation.

In a book slated for publication Oct. 29, retired Navy commander Guy Snodgrass, who served as a speech writer to former Defense Secretary Jim Mattis, said Trump called Mattis and directed him to “screw Amazon” by preventing it from bidding on the JEDI contract, according to an excerpt of the book seen by Reuters ahead of its release.

“Were not going to do that,” Mattis later told other Pentagon officials, according to the excerpt. “This will be done by the book, both legally and ethically.”

Mattis resigned December 2018, his successor put Amazon's contract up for review in August.

It's not clear that he committed to a contract or was offered a contract. Generally, the elements of a contract are: offer, acceptance, consideration, mutuality of obligation, competency and capacity. We don't know.

The schema is not defined in json, which is good, json can't have comments. Graphql requests and responses are json, and you can get a json representation of the schema using the introspection api.

I for one do not like json, the only formats I can think of that I like less are xml and yaml. I'd prefer a protocol with a binary implementation, it must support comments, I like type annotations, and a schema language would be great.

I've been working with Amazon's ion lately and I've enjoyed it. It has text and binary representations, fields have types (in binary), it can be represented as json (you lose annotations)

The article presents evidence for a correction, but not a crash. I'd be interested in a revision that compares data around the housing crash of 2008- to housing data for previous recessions to identify the keys to a housing crash. Was there any smoking gun that gave a clear indication that this was no ordinary housing downturn?

Then, the article could compare the data currently available with the unique features of the 2008 crash and earlier declines.

Otherwise, using the term "crash" doesn't seem justified.

I have a similar issue with 3D graphics at work. We use a HTC vive with a software called Revizto to view industrial 3D models (for what is essentially power plant designs). The problem is that you can only load part of the model because it's apparently too complex for the system to handle and some objects won't render. Say you loaded an architectural model of something a football stadium, with Revizto you can only run perhaps 1/20th, of the model in VR. It works a little better in you double the PC's video RAM, but not much. It's a major pain. However, you can run VR games that seem far more complex, the environments go on forever, and you can even have smooth animations and physics interactions.

What gives? It seems to me I should be able to run my 3D models in VR to run as smoothly as a game. How do I load a complex 3D model to run smoothly in VR?

Yes, for purposes of the discussion about installing roofs, you are correct. I am just bemused by this statistic. The vast majority of “homeowners” are paying a lot of interest to lenders.
> Duane’s Law says that if a body is periodic in space in a given direction then momentum exchanges in that direction are quantized. That means that the emerging electron is more likely to go in certain directions than in others, depending on how many quanta of sideways momentum are exchanged. Guess what? When a stream of electrons is sent through, a ‘diffraction’ pattern results.

If this "direction preferentiality" were all that were needed to cause a diffraction pattern, then we should see it if we run the experiment with one slit closed for a while, and then the other slit closed for a while.

But that's not what happens! If you send particles through only one slit, you do not get a diffraction pattern! (Actually you do, but the valleys are spaced far wider than those with both slits open.) No diffraction pattern = no valleys. Running the experiment again with the other slit closed can't add those valleys in. This is logically no different than individual electrons simply "randomly" entering alternate slits, so that can't make a diffraction pattern either.

What am I missing? It seems like the author is trying to explain double-slit purely in terms of statistical ensembles of quantum-ish particles rather than exploiting the full generality of quantum fields, which makes no sense simply by looking at the results of a single- vs. double-slit setup. (e.g. https://en.wikipedia.org/wiki/Double-slit_experiment#/media/...)

What even is a "hitman?" Seems like it's just an arbitrary term that can be used to mean anything. Maybe I'm a hitman. Maybe you're a hitman. Who gets to decide what a "hitman" is and what that means? What is their agenda?

And "murder?" We don't even know what life is, how can we be so arrogant as to define something like "murder" on so murky a premise as the ending of "life?" That's like dividing by zero. The commonly accepted list of the characteristics of a living thing (it consumes material to feed itself, it can grow and reproduce, it can die and respond to its environment) also apply to fire, so obviously firemen are also committing murder, and firemen are also hitmen.

Someday when we all tumble into the Orwellian nightmare this slippery slope is sending us down, we'll all be "hitmen" and everything will be "murder." This whole "hitman" thing is so obviously just another thinly-disguised form of thoughtcrime perpetrated against free-thinkers who don't blindly conform to the status quo.

> If too many people build solar, the utility can't build new infrastructure and charge everyone for it.

Right. Because solar does not play well with existing infrastructure but solar needs the grid to be even close to viable. It needs it because it is a diffuse intermittent power source, where the peak power generation does not actually match peak power use. Solar overproduction cannot be saved for later either, meaning that you have another infrastructure challenge of dealing with overproduction when you don't need it.

In general, solar only really works if it is paired with a a traditional power generator that can ramp up quickly (when there is no solar output) and ramp down quickly (when solar output is high). The only power generators that can do that are ones that burn fossil fuels. That's why natural gas companies are a BIG lobby group for solar. That's why Germany is signing massive, multi-decade deals to ship Russian gas, as they expand their wind and solar infrastructure.

If you care about getting rid of carbon emissions, solar is a disaster. Not to mention energy use in building panels and the number of rare earth materials each one needs, the problems with recycling them, and their land-use requirements and the environmental impact of that.

>It is good for everyone when rich people buy solar
