has anyone heard of "relativistic dynamics of a charged sphere" by yaghjian i picked it up from a pile of books to be thrown out along with gravity decoded by borello.
i see it goes for 85 bucks on springer i feel lucky
> A certain Dr. J. H. van't Hoff, employed by the Veterinary Academy at Utrecht, appears to have no taste for exact chemical research. He found it more convenient to mount Pegasus (borrowed no doubt from the Veterinary Academy) and to proclaim in his La Chimie dans l'espace how on his daring flight to the chemical Parnassus the atoms appeared to him disposed in world space.
Hegel divides his philosophy into : 1. Logic 2. The philosophy if nature 3. The philosophy of spirit
i dont understand what he means by spirit
according to this website : In Spirit we have an all-inclusive relation. Spirit is both a self-reflective, all-inclusive Logic as well as including Nature while remaining different from Nature.
oh, by "spirit" he means "mind". it says in German there is no distinction between spirit and mind. Geist is the word for spirit, mind, soul, etc
this entire thing seems to be a theory of mind. it talks about divisions of the mind and how the mind works and what it wants (freedom)
but again, none of this is with evidence. it just sounds like assertions, like the goal of mind is freedom or that the spirit shapes the nature
@RyderRude 1. Hegel is notorious for being extremely hard to understand even in the original German. 2. "Geist" does not exactly mean mind, no, neither in general nor in Hegel. There's a reason it's usually translated as spirit in Hegelian contexts.
philosophy just seems like whatever philosophers want to assert about what the mind is. it's just assertions like the mind has certain divisions and stuff. we are just supposed to accept these assumptions
ans based on these assumptions, they derive conclusions about how society should be
but none of these assumptions can be tested in the first place. so no one can trust their conclusions about society
Prior to GR, there used to be a freedom is defining energy, because conserved quantity + constant is also a conserved quantity. also the Hamilton's equations work out
but in General Relativity, energy is literally an observable. there is no gauge freedom like the addition of a constant
prior to GR, only differences in energy were observable. and ther was an arbitrarily chosen gauge. like for potential energy where we choose a point at infinity
@Amit, the more I think about it and the more time goes by, your decision to discontinue college education and do self studies makes more n more sense Tom me. ATP only my mum n dad, and the uncertainty in life that follows are stopping me from taking this same decision
I can't speak for others but where I study, the institute actively tries to kill your motivation for the subject
The concept of open University is pretty great in India. Cost is dirt cheap, and you can study on your own all the time, you only need to drop in physically to write examinations. Once you have the degree, you can write grad entrance exams to get into top places
Going outside India for grad school will be difficult in such a case, I would presume. Where things like the uni you studied in, cgpa etc matter
@nickbros123 I doubt they're "actively trying" to do anything to your motivation at all :P
Most of us grow up in a school system where we aren't really ever given much choice of what to learn, and then we're expected to somehow find intrinsic motivation to study things at university where we're given much more leeway. Some countries seem to try to "fix" this gap by making university more like school, but that just delays the "intrinsic motivation" cliff for a few years
@ACuriousMind this is what happens, but, I am motivated more than ever to study math and physics;, if the institute lets me just sit down with a textbook without pestering me, I'll be the happiest man.
You see, at my place, things pile up against people with this mentality. 1) there are 4 subjects to study, not 2. 2)there are labs, for all of the 4 subjects 3) attendance to class is compulsory to write the finals. Also, those who are "jack of all trades", ie spend equal, but effectively less time to each and every subject, end up getting the 10s and 9.5s. Cgpa is not subject wise, it adds everything up
Sorry if I'm ranting, it might not be a general thing at all, it's just my place is like this
oh well, I agree mandatory attendance for classes mostly sucks
But labs, however annoying they might be, I think are a really valuable experience especially for theorists :P I do think it is important to have some basic idea of how one would actually go about testing theories and setting up experiments
I'm not sure what you mean by "4 subjects"
are you saying you have to do some biology or chemistry and can't only do physics and math?
@nickbros123 There's value in getting people to broaden their horizons a bit. Honestly I see nothing wrong with people having to take a biology class or two. I'm not sure why this would "kill your motivation" (except perhaps to engage with that one class you're forced to take but don't want to)
@ACuriousMind the erosion of my sense of self worth as I see my cgpa drop is what tries to kill my motivation. It's a psychological thing. Moreover, I'm not good at biology, or chemistry, and the presentation doesn't help either. The instructor assumes prior knowledge from highschool, but my HS did not have bio, for the last 4 years of my schooling.
I (used to) think that if my grades were high I'm in the right track, and that was the case for me in school, where things were extremely objective. No one cares if you showed up to class, if you get the best marks in the exam(which was a replica of the JEE advanced, which is purely objective), you were clear. Now it's not the case
@nickbros123 Yes I was going to say exactly in relation to grades that you're better off imo settling for crappy grades but getting through the degree. I don't regret how things turned out in general for me 'cause it's been such a long time since uni, but in retrospect, it feels better to just finish whatever you start. Quitting should always be a last resort for whatever problem you're facing ;-)
..and BTW even in my case, I did try to slow down my studies before quitting (in the last two semesters, I only took 2-3 courses per semester) but then I decided to quit anyway ;-) water under the river
@RyderRude Ever since I left uni yes, on and off...
Desperation is often intelligent and seldom useful, lol
