Nugatory replied to the thread What papers is the CO2 climate change theory based on?.Back in 2014 we decided that we would allow science-based climate change discussions as described in the sticky that @berkeman posted... -
Nugatory replied to the thread B Can an expanding EM be quantized: E=mc^2?.It’s best not to use the word “expand” at all, but instead rely on the math: do the math and you will be able to calculate the EM field...

Nugatory replied to the thread B Can an expanding EM be quantized: E=mc^2?.Assuming that by “em” you mean “electromagnetic”(although that’s the only kind of photon), then yes, the upper case letter ##E## is...

Nugatory replied to the thread B Debating the Validity of a Conversion Factor for Mass-Energy Equivalence."Someone posted" is not a good start to a thread, as without the source we have no way of knowing whether you've misunderstood something...

Nugatory reacted to hokhani's post in the thread A Angular momentum uncertainty principle and the particle on a ring with
Like.
Also in classical view, when a particle is rotating about z-axis, the x,y components of angular momentum are not zero. They are zero in... -
Nugatory reacted to jbriggs444's post in the thread A very naive encryption scheme : How would an expert crack it? with Like.
This original series of digits. Is it finite? If the original key is finite then one should instead use a cryptographically strong...

Nugatory reacted to JimWhoKnew's post in the thread I Validity of identical eigenfunction of commutating operators with Like.
As @PeroK replied in #8, nothing is wrong with #7. Only basis states are considered there. But your ##\psi## in OP (#1) is a...

Nugatory replied to the thread I Validity of identical eigenfunction of commutating operators.If two operators commute, then at least some of the eigenfunctions of one will be eigenfunctions of the other - but not necessarily all...

Nugatory reacted to Lord Jestocost's post in the thread I Is there any interpretation of QM that doesn't clash with intuition? with Like.
The appropriate question would be: Is there any interpretation of QM that doesn't clash with 'classical' intuition?
-
Nugatory reacted to gentzen's post in the thread I Is there any interpretation of QM that doesn't clash with intuition? with Like.
Well, that depends on the version of Copenhagen. Bohr's version is inherently non-relativistic. The version by Heisenberg and his...
-
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...
