Your argument seems to be based on fixed point charges and a disregard of the other mobile charges in the conductor. Charges in conductors are assumed to be mobile under the influence of an electric field. The redistribution of the mobile charges of a conductor due to an electric field causes the...
Can anybody explain to me what the above answer is trying to say ?
He keeps linking to Wikipedia pages which are way too over my head :/
@Droleulb Thanks. For what it's worth, I apologize if anything I said offended you in the past. Miscommunications, falling out with your friends and being mad at them - it's all a part of growing up.
Today I dreamt my professor suggested me to go to a conference, and I did go to and felt great. It's been long since I last went to a conference. I really long for going to a conference.
i think in my past dreams there are 3 conferences, one of these is about some weird kind of quantum gravity thing, but after waking up, I found that none of the stuff makes physical sense
It is possible some aliens obey the dark forest rule and the revised version, but we cannot tell if they obey other rules. For example, they may simply don't want to be discovered or does not have the correct tech to discover us. This question is a wide open one with many possible answers
So are you saying that this is probably not a good Fermi Paradox solution either?
Because here is the idea: I can combine the Dark Forest Rule with the Great Filter (aka: self-destruction) with some elements of the Rare Earth Hypothesis.
So, some civilisations never choose to expand, others blow themselves up, others colonise the Galaxy, but many worlds are still in the primordial Earth phase and have yet to develop complex life.
And those that DO expand....well, they are not really guaranteed to be friendly.
@Secret? Is that a better solution or rather...combination of solutions?
I'm not sure if such an axiomatization is possible, because axiomatizing real numbers is already impossible to do in a first order manner, as the first order axiomatization of the real is the same as for any of the ultrapower extensions of the real (the first-order axioms of $\mathbb{R}$ are the ...
Suppose you have $n$ particles with masses $m_1, \cdots, m_n$ with position vectors $\vec{r_1}, \cdots, \vec{r_n}$. Now without any forces except gravity acting on them, conservation of mechanical energy for multiple particle states that the quantity $$\displaystyle \sum_{0 \leq i \neq j \leq n} ...
I seem to have heard inner automorphism. I wonder if the inner here means the same as there. But I forget what inner automorphism means and I am trying to recall now.
In abstract algebra an inner automorphism is an automorphism of a group, ring, or algebra given by the conjugation action of a fixed element, called the conjugating element. These inner automorphisms form a subgroup of the automorphism group, and the quotient of the automorphism group by this subgroup gives rise to the concept of the outer automorphism group.

If G is a group (or a ring) and g is an element of G (if G is a ring, then g must be a unit), then the function

@AlexKChen Obviously you remember what I previously told you about posting questions here right after you ask them and yet you decided, again, to simply ignore it. This is not acceptable behaviour.
The one he described in Physics of the Impossible.
Michio Kaku supposedly made a magnetic field 20,000 times the strength of Earth's magnetic field trying to make a particle accelerator.
And.......he kind of....used 181 kg of transformer steel (400 pounds for the Americans in here) and 35 km worth of copper wire (22 miles for Americans) just to make the particle accelerator.
@FutureHistorian any info on web? was it operational? did he get any results? anything published? reminds me of highschool/ college science fair projects... surprising to hear about from one of the worlds foremost/ most famous theorists... do you have any interest in any other physics experiments?
@CooperCape By "strict" I meant that the minimum age is 18; non-liquor is 16 here so the age range for Germans old enough to be allowed on SE but not old enough to drink is rather slim :P
In fact, it's zero now that GDPR seems to have caused SE to raise the minimum age to 16 for European users
