Nugatory's latest activity
-
Nugatory replied to the thread I Is there any interpretation of QM that doesn't clash with intuition?.They don’t. Copenhagen is inherently non-relativistic because of its collapse model so we only use it when relativistic considerations... -
Nugatory replied to the thread A very naive encryption scheme : How would an expert crack it?.No. What makes a Caesar code a Caesar code is that there is a position-dependent one-to-one mapping from each character of plaintext to...

Nugatory replied to the thread A very naive encryption scheme : How would an expert crack it?.If only one K is number used for multiple messages, you just have a Caesar cipher, and as @Fresh42 points out, these are vulnerable to...

Nugatory replied to the thread A very naive encryption scheme : How would an expert crack it?.Perhaps not, but that’s the wrong question. Cyphers must be designed on the assumption that an attacker knows everything except the...
-
Nugatory replied to the thread I Could there be a non local theory without action at a distance?.The difficulty with any "travelling between measurement outcomes" model is that it implies a direction of travel: in any particular...

I don't think there is one, but you can reply saying "posted in error, please don't waste your time replying" and then report your...

Nugatory replied to the thread I Could there be a non local theory without action at a distance?.I won't presume to speak for the Bohmians, but if I understand properly, non-locality in Bohmian mechanics avoids conflict with...

Nugatory replied to the thread I Could there be a non local theory without action at a distance?.To be consistent with experimental observations that something must (as pointed out by @DrChinese above) travel at superluminal...

Nugatory reacted to SergejMaterov's post in the thread I Would gravitons theoretically act like photons? with
Like.
Gravity’s coupling G is dimensionful, so you only get a meaningful gravitational fine‑structure constant once you specify masses or... -
Nugatory replied to the thread I Freefall and gravity.Proper acceleration is measured with an accelerometer. Imagine a cubical box with six springs inside; one end of each spring is...
-
Nugatory replied to the thread I Freefall and gravity.Objects "experiencing gravity", whether in freefall or not, is not part of the theory of general relativity; it's a misunderstanding...
-
Nugatory replied to the thread I Hydrogen 21 cm line time?.No. I am sorry to say that it is complete nonsense. The Bohr was abandoned long ago because it does not adequately describe electrons...
-
Nugatory replied to the thread I Hydrogen 21 cm line time?.What do you mean by "the hydrogen cloud"? But no matter what you mean by that, it makes no sense to talk about the speed of a bound...
-
Nugatory replied to the thread I Shwartzschild coordinate system.It cannot be done, for about the same reason that we cannot find a transformation between latitude and longitude on the curved surface...

Nugatory replied to the thread B Simple mass/scale puzzle.It doesn't. Several posts have already done that: Demystifier's #71, multiple posts from multiple people suggesting that you draw a...
