The measurement device gets entangled with the spin - which is in a superposition - and then I get entangled with the measurement device and for got measure the entire environment. How does this avoid the many worlds? If the measurement dev

The interesting thing about entanglement is not the correlation per se. You can take a pair of hand gloves, put each one into a box, and send them to opposite ends of the universe. When you open one box at one end of the universe and see th

Sure, if you would know the spin direction before the measurement, you could align your measurement device accordingly and get a predictable answer and spin state would remain unchanged as the particle is not in a superposition for that mea

I am not a physicist, but I thought that it is generally accepted that decoherence does not solve the measurement problem. It explains why quantum effects are not observable in a noisy environment but still does not explain the non-unitarit

Quantum systems evolve unitarily, measurement devices collapse the wave function which is not unitary. And there is no accepted consensus how those two things fit together, just several ideas like Everett's many worlds which solves the

A similar result for superposition would be huge, I guess, after a century we could finally understand what qualifies as a measurement device, why we do not observe quantum effects at macroscopic scales, what actually saves or kills Schrödi

I will give that one a try, might at least speed up things, but it still misses hyphenation and justification. Hitting enter when reaching the guide line takes the least effort but this might be really handy when editing existing comments,

I do not disagree with you, but having the news and weather forecast in the start menu is seemingly a more important feature then having a good search functionality, what can we do? And maybe that even makes sense, maybe we are just not the

We were talking about somewhat different things, you meant doing it mathematically, sure, no problem, pick an infinite random sequence, I understood the question to mean how to do it in practice. Actually I had something even stronger in mi

At the cost of a huge increase in complexity and maintenance costs, that is the trade-off.

I agree that searching on Windows sucks but I guess there is a trade-off to be made. You can use very abstract APIs that will work for all kinds of file systems, whether a local disks, a DVD, a USB connected phone, or a network drive, but i

I used UltraSearch [1] a few times and I think it does a similar thing to Everything, access the NTFS data structures directly so that it provides essentially instant search results and directly after installation without the need to build

We actual know some normal numbers [1] but they seem to all be synthetic. I would guess they have a lot of local correlation because of the way they are constructed and the comment I responded to explicitly mentioned no self-correlations -

Would this not require generating an infinite number of random numbers which you can not do? Or can you actually generate a random Cauchy sequence from a finite set of random numbers?

Conjectured to be normal.

The flexible pipe has to be strong enough to withstand 160 bar, wide enough to allow the necessary flow, and at the top tolerate one mile of pipe - filled with water - pulling on it. I have no intuition how challenging that would be. Or may

Here is another ooh, this is the thread to ask my question in. For years I wanted to make a Visual Studio [Code] extension that justifies comments as you type including hyphenation but accepting additional spaces as necessary. I never dared

This [1] is the best I could find with a quick search, admittedly far from ideal, but it has some numbers to start with and might help to locate better data. [1] https://www.independent.co.uk/news/science/it-safe-t

Not an expert, just searched for it, but this article suggests - just skimmed it - that while most groundwater is indeed not that deep, there is groundwater several miles down and the interaction between deep and shallow ground water is not

According to the company, if the reactor needs inspection or servicing, it can be hauled to the surface by cables in about an hour or two. What happens to the two one mile long pipes attached to the reactor?

In case of physics we do not really have access to the later kind, every theory is a current best guess that might at any time turn out to be only approximately correct or under certain circumstances. General relativity is almost certainly

Everything falling at a constant speed of 9 m/s takes this probably a bit too far, on Earth this will only be true for tens of milliseconds before the speed is of by a few percent. Had you said every objects accelerates with 9.81 m&#x2

Even wrong theories can be useful in some contexts, Newtonian gravity for example. Newtonian gravity is not wrong, it is pretty good model of gravity in a certain region of the parameter space.

The problem is that you are trying to use a document markup language to create an user interface including designing and styling the controls themselves. Also computers were not black and white in the 90s.

The number of parameters is just the wrong metric, it should be the amount of information contained in the parameter values, their entropy, Kolmogorov complexity or something along that line.

Having diagrams and code is bad, they are redundant, they will get out of sync, you will have to figure out whether the code or the diagram is correct. That leaves us with code generation from the diagrams, or more accurately from the langu

For 90° in 9 ms and a 57 mm cube, I get accelerations of 4.4 million degree per second squared and 225 g at a corner assuming equal and constant acceleration and deceleration during the turn.
