FactChecker reacted to PeterDonis's post in the thread I Wigner's friend and quantum tunneling with
Wow.
In such cases, there is no decoherence, so even according to standard QM, there are no objective measurement results; it's no different... -
FactChecker replied to the thread Conflicting definitions of linear independence.The second statement is not a "definition" of independence, it is a statement of (a proposed) fact about independence.
-
FactChecker replied to the thread Defining Analog Computer Power.I would say not. Analog computers may not need DACs or ADCs at all. And a complicating factor is that the conversion between analog and...
-
FactChecker replied to the thread B Simple mass/scale puzzle.Your logic was fine from the beginning, so the question is how to make it more formal. Since there is no net torque on the pulleys...

FactChecker reacted to Charles Link's post in the thread I Geometry problem of interest with a 3-4-5 triangle with
Like.
It was a week or two ago that a friend of mine showed me a video of interest. The video is somewhat incomplete mathematically, but... -
FactChecker replied to the thread Defining Analog Computer Power.It is complicated. Just like digital computers, with several indicators of capability (RAM memory size, HDD size, MIPS, clock GHz...
-
The bandwidth of a computational feedback loop, and the settling time of a digital to analog converter are relevant concepts.

FactChecker replied to the thread Intersection of a circle and a sine curve.Proofreading a book is a tedious, endless, thankless, job. No matter how long and hard you try, some errors remain. IMO, there must be...

FactChecker reacted to hutchphd's post in the thread Intersection of a circle and a sine curve with Like.
i still decry thae question. More than 16 is a (not the!) correct answer. I think it unwise to include an example whose...
-
FactChecker replied to the thread Intersection of a circle and a sine curve.I agree. But I don't think the authors realized the ambiguity, so I am not inclined to be very critical of them.
-
FactChecker replied to the thread Intersection of a circle and a sine curve.It is only wrong if you assume the most trivial interpretation of the question. I would not do that. Suppose you interpret the question...
-
FactChecker replied to the thread Intersection of a circle and a sine curve.It's tricky to state that problem unambiguously. I wouldn't be too hard on them for any ambiguity.
-
FactChecker replied to the thread Intersection of a circle and a sine curve.I would say ""out of all possible circles, what is the maximum number of times any circle can intersect the sine function." IMO, that...
-
FactChecker replied to the thread Intersection of a circle and a sine curve.Until you mentioned it, I didn't notice that it was ambiguous. I took it as "given all possible circles, what is the maximum number of...

If all ten had been phone-free it would be one in ten billion. But there was one user. That makes it 90 times more likely. If I...
