No, it is not possible to communicate any information by measuring one side of the quantum state. This is the no communication theorem: https://en.m.wikipedia.org/wiki/No-communication_theorem It's only possible t

This is not how entanglement works, and while people do understand how entanglement works, it's a little subtle. When you measure your atom on earth, you will get results with certain probabilities. When I measure my atom on the moon,

US average gas price is currently $4.60/gallon. UK average gas price is currently $7.99/gallon. Depends on how much more efficient the electric car is than the gas-powered car.

After the elimination of candidates due to Peter's first comment, the entry in the product map with value 7920 should also have the candidate (80,99). The whole point of this step is that there should be no single-candidate entries lef

That's not exactly what the page you linked says. The existence of one-way functions implies P != NP, but the reverse is not known to be true. In particular, it's possible that P != NP, but also no one-way-functions exist. See Imp

As far as I know, in Magic: the Gathering, the best bots are far worse than most players. Part of the difficulty is that the rules are so complicated that there are only a couple of complete rules implementations. Beyond that, it's an

One option would be to try to doxx them, either as part of a criminal investigation or via private investigators. I bet these groups would be much less effective if their identities were publicly known. There's a reason they're no

In the early universe, light could not travel freely, because the ambient temperature was hot enough that the universe was filled with plasma. The end of this period is called "recombination", and the light from that point in time

Uncompressing files is a big complicated task with lots of fiddly little details. There are tons and tons of options, and that means tons and tons of attack surface. Besides symlinks, there could easily be all sorts of other errors that wou

The official name of the LHCb experiment is the "Large Hadron Collider beauty" experiment, as named by the scientists themselves. So "beauty quark" is more correct in this context. https://home.cern/scien

That's why the microwaves approach might be preferable to the laser approach: "Safe, low intensity levels hardly stronger than the midday sun. Birds and planes wouldn’t notice much of anything flying across their paths."

According to Wikipedia [0], about 500,000 Horseshoe crabs are bled each year, with a mortality rate of 5-30%, depending on the source. In contrast, about 1,000,000 Horseshoe crabs are used as fishing bait each year, in the United States alo

To understand what's described in this article, it helps to start by understanding how a lateral flow test works: [0]. Basically, the active ingredient in a lateral flow test consists of two components chemically bonded together: a col

I don't think that owning a house is nearly out of reach for a family making $62k/yr. Standard advice is that one can afford a house costing 2.25 times one's annual income. That means the median family can afford a $140k hous

The WHIM is actually extremely non-dense: 1-10 particles per cubic meter. It turns out that matter can be extremely hot without being dense at all, as long as there's nothing to cool the matter off, as is the case in the space between

Imagine a piece of paper with a Y shaped cross section. By smoothing down any two arms of the Y, you can read what's written there. By flipping over an arm, you can read a different side. There are three sides available.

That blow up is quadratic, not exponential: "This is not classic catastrophic backtracking (talk on backtracking) (performance is O(n²), not exponential, in length), but it was enough."

You're right, it's average wait time over all tasks. However, processing the shortest tasks first doesn't delay the long tasks much, if length is reasonably variable, because the short tasks are almost negligible to the long

In that setting, the line queue is 30 people long, on average. Sometimes more, sometimes less. Because 5.8 people arrive an hour out of the maximum of 6 that can be served an hour, and 6/(6-5.8)=30, the average queue length is 30.
