Duane doesn't explain double slit experiment. It says momentum exchnge is quantized if you direct particle at lattice and this gives same pattern as interference.

If you consider single electron in this interpretation, point like particle without any associated wave or ability to be in more than one point of space at the same time ... when it is directed and passes through one of the slits, it produces the pattern but only if the it potentially could have been directed at the other slit.

How the hell what could happen with a particle (but didn't) could influence what actually happened to the particle (quantized, not normal momentum exchange)?

--

For me the way to deal with weirdness of double slit experiment is that electrons and such are just waves, all the time. Fuzzier, sharper but always waves. The only thing that makes us think that's not the case is that, when they exchange energy and momentum, it's governed with same equations as if they were two balls bouncing off of each other.

The truth in my opinion is that electrons don't bounce like tiny balls, but balls exchange energy and momentum as if they were huge, very sharp electrons. Macroscopic balls are waves too, but imperceptibly because they are build out of bazzilion particle waves all tangled together into a very constraining packet.

Key Design Components and Considerations for Establishing Single-Payer Health
It’s simple to solve, but right now it’s also expensive and most of the consequences of doing nothing will impact a different group of people than those who are causing the problems.
I sort of agree, but I think you're too harsh. Having taught phase diagrams to freshmen, very smart freshmen, as with everything else it comes down to familiarity and practice. I tend not to look down on people for not knowing stuff they're not familiar with, I'm sure they could all get it with someone who can actually guide them through it.

But I do appreciate a simple, inexpensive design of course. But they're so hard for people to make if they don't understand the deep details of everything in the system, and once the knowledge is split between two brains then it's a lot harder to spot inconsistencies. But I also can hardly blame people for throwing in the towel on deeply researching the sheer vastness of the McMaster, Swagelok, and Digikey catalogs. Much less ASTM standards or the ASM handbook.

I work on building a lot of surprisingly easy things like electromagnets and battery charging circuits and low noise filters and precision temperature controllers and such like that in-house because it's shocking how bad and expensive stuff made commercially usually is. Just yesterday I was replacing a flow sensor in a water pump to water cool a vibrating scanning magnetometer my office mate designed. It's a fun line of work. I also do stuff on the side as a consultant along these lines to scratch the "let's make something people can use in industry" itch (http://neltnerlabs.com/).

But my biggest pipe dream for the past 9 years has been using AI tools to close the loop around synthesis and testing and predicting properties for heterogeneous catalysts. Equipment is a key part of that dream, sadly Google was uninterested (no ads?) and I've only ever found a handful of companies working on it all of which don't quite seem to get just how big a deal it is almost certain to be. At least the national labs are catching on.
Short of green spaces, or short of useful green spaces?

No, that means what they thought or intended has absolutely no bearing on if they are guilty of having committed the crime.

The thought side of a crime, or the intent is mens rea, while the action of that crime is actus rea.

Normally in a crime both factor into the decision. For instance, should you murder somebody you committed the act of murder. What you intended or thought about before or during is the intent side or the mens rea part. Planned and murdered is a different charge than accidentally killed somebody.

So suppose we say the bar for murder is mens rea of "acting knowingly", and the act of the victim dying by your direction action.

But, manslaughter is mens rea of "acting with negligence", and the act of the victim dying by your direction action.

These are in effect two different crimes. The difference between them is what your intention was. If you want certain classes of murder you have to prove premeditated intent, because it's a part of the crime.

Now, strict liability says, "Mens rea does not matter here, it is not a part of the definition of this crime." What you thought or intended is simply not a part of what the court is there to consider.

The court is only there to consider is the action was done by you, and if so, you are guilty.

Edit: The handicap and small child, as far as I understand are not protected from being prosecuted in a strict liability charge in a court, but are simply less likely to make their way to a court.

Physics PhD here. I'd call it both. A lot of what applied math departments study are problems of physical nature; and a lot of physics research boils down to applied math. (Broadly speaking, all theoretical physics is applied math.)

I doubt that climate can shift so quickly that humans can't adapt at least their most important cultures. We're very good at this, and very quick, and we don't need to produce food anywhere near where it's consumed.

Although of course the ships that bring immense amounts of food across the globe have been built, and are operated, with fossil fuels. As is our agriculture. Again, increase the cost of the fuel that makes both possible, and people will die.
It seems pretty clear to me that the root of all this nonsense is artificially low interest rates for a decade paired with increasing wealth accumulation among a small portion of people. The former has led money out of traditional investments and into VC seeking high returns while the latter has led to an explosion of angels and LPs with too much money and not enough productive things to spend it on.

Unfortunately, it looks like neither of these is going to be resolved any time soon. However, we at least now have a couple years worth of public investors who've been burned this time around and startup kids who got hosed by highly devalued options before they could cash out, so maybe a small amount of sanity will return to the startup world.

A list of nonfiction journalism from 2017 that will stand the test of time
I've used a bunch of e-ink devices. Here's my thoughts on them.

Sony DPT-RP1: 13" display, only displays PDFs. They added a feature in it to one of the updates that you can use it as an external monitor. Haven't tried it yet. Sony is extremely slow when adding new features and updates, it seems like their release cycles are every 2 years. The screen is I think the best on the market right now.

Sony DPT-S1: 13" display, only displays PDFs. This is the older version of the RP1. Oddly enough, it has a lot more features software wise. It has a web browser and SD card reader. Using a browser on an e-ink display is possible, but it's painful to use. It sucks typing out a URL and scrolling because of the refresh rate. It would be somewhat better if there was a way to turn through webpages instead of scrolling so the screen would only refresh once.

Onyx Boox Note 13": Onyx e-ink devices use Android (older versions of Android). The good thing about these devices are that they could display almost any type of format - PDF, Mobi, Epub, etc. The UI is somewhat clunky and could use some polish and so could some of the English translations. The updates come more frequently but it's a gamble on whether the new features are worth dealing with the new bugs they introduce. The larger versions you could also use as an external monitor as well.

Remarkable: 10.3" display. Best note taking e-ink display I've ever used. It's almost like writing on paper. I would only use it for drawing and note taking though. When transferring PDFs, it converts the files to their own format. They also have an app which allows you to sync files with your phone. Their last major software release they had to pull twice because of bugs.

Amazon Paperwhite: Nice small device which allows you to read in the dark. Most of the large e-ink displays do not have backlights. Great for reading anything that doesn't have graphics. Do not read PDFs on them.

Microsoft Surface: Not an e-ink device, but portable enough that you can read any format on it and more. Comparable in price to a lot of the 13" e-ink displays since they normally go for $500-800.

I've never found one best e-ink device out there for all uses. They all have certain things they excel at. They are all lightweight low-powered devices though, so if you want to do anything besides read or write text on them you'll probably end up being disappointed.
there are many arguments, some unfortunately rabid ... this one feels well put together.

Oh my! Your story is a very significant overlap with mine!

I started programming at an age of 11 years, when I did not even know the meaning of sin and cos.

The spinning 3D ring I had created was slow like yours, speeded up by caching sin and cos values like yours. The final one had entire frames precomputed in memory and cycled by hand-written machine code into the video memory space. That last one was when I was when 14 years of age.

How this doesn't get these cops fired for trying to falsely arrest someone using a test they likely know is flawed is insane (who would ever look at a white spot on the top of a car and think "yep that's cocaine"??). If there was any sense and lack of lobbying by police unions in the US it would be an easy priority to draft better laws on actions of cops.

Most of your proposal are unrealistic. For example:

> Instead of water line pipes, pull water out of the air.

You need a lot of energy to transform water into vapor and you need to remove and dispose the same amount of energy to transform vapor into liquid water. Every three months there is a new Kickstarter scam that propose something like this. Sometimes it's an overoptimistic idealist, sometimes it's a plain scam, sometimes it's difficult to be sure. After a few months and a few millions in development, they just reinvent a dehumidifier with a fancy box.

> Find every crop that requires stable land and predictable weather and farm it in a shipping container.

The current farms cover approximately 40% of the land surface. So you need to build a huge number of shipping containers. Will they have a transparent top to get free light? What about irrigation? Why is it better to use shipping container instead of the current method? Is this just a grrenhouse
Social media algorithms of course influence the Overton Window. It doesn't matter if the developers are consciously conspiring to do it or not; algorithmic bias is naturally inherent.
I experienced this too, Facebook will block most torrent links, regardless of if they're legal or not. I've taken to encoding these with Base64 first and instructing the recipient to decode them.
Not quite. Taking carbon out of the ground isn’t a problem; bringing carbon into the atmosphere is. It also doesn’t matter where the carbon comes from.

> This is why a horrible crime like rape is typically not punished as strictly as murder: if the penalty were the same, why not do away with the witness.

FWIW this probably doesn’t make any sense in practice. Most rapes are done by people who think they will get away with it either because it’s very hard to catch or because they have sufficient social power. Now, these people are clearly huge pieces of shit, but they’re probably not going to decide to murder the victim to minimize legal risk just because the potential penalties if convicted are closer. Murder is much harder to get away with and social power is much less likely to save you. Also, people don’t like committing murder generally, even if they’re apathetic enough to commit rape. The proposed logic feels like it describes the world in which rapes are committed by scary men who randomly break into your house because they’re just criminals. Not to trivialize the unfortunate fact that the latter does happen and it’s very sad, but it’s relatively rare.

Continuing to encourage car usage will not solve environmental problems. Governments should invest in infrastructure to avoid one person in a car during peak hours. This suboptimal commute pattern is a major contributor to not only green house gases but also traffic congestion and reduced quality of life as a result.

One unexplored option is to build freeway bus services - build pickup and parking lots near freeway exits and reserve diamond lanes exclusively for commuter buses. Unlike trains this can reuse existing infrastructure and works well with company shuttles and the like.
What people _believe_ is largely irrelevant in almost all situations, whether you mean the voters or the elected officials. Only actions matter.

This is not just semantics, some who believe in global warming fly every month or week, some who don't believe in global warming have not flown their entire life (to pick just one example). The latter do more to mitigate it than the former.

Many times if GIF is converted to video it will ruin the pixel art, or in some cases even produce bigger file [1]. I get the efficiency argument for conversion to video, but in some cases it is a no-go. There should always be an option to not convert to video.

Does anyone have any _aphysical_ 3D sites? Or videos, sketches, inspirations, whatever?

I'm focused on HMDs and DIY shutter/anaglyph/wiggle 3D and hand tracking above laptop keyboard. For non-novice professional GUIs, why simulate the physical world? That's a big bag of restrictions, unlikely to align well with desired domain affordances. It feels skeuomorphic - nice for onboarding novices, but generally not where you want to end up. But with VR currently focused on gaming and presenting the physical world, and AR on onboarding and reality overlays, there's not a lot of inspiration around for 3D UI design where the "R" isn't a priority.

I don't deny that we are destroying the world and the ecosystems, but how is CO2 responsible for the garbage in the oceans?

10'000 years ago we were living an ice age. The prehistoric men didn't produce any CO2, yet our world has been warming up since then.

> allows you to detect the path AFTER the photon has traveled through

It is NOT AFTER: "Why delayed choice experiments do Not imply retrocausality"

https://link.springer.com/content/pdf/10.1007%2Fs40509-014-0...

tl;dr: the detector collapses the state, detection does not mean both paths were not "taken". This is the same as detecting a photon on a screen after a double slit.

Disclaimer: I only skim QM stuff, I am not a physicist
