Like the mass or charge ?

#

I mean they are also intrinsic and measurable physical qt's associated with matter

storm sage
#

I'm not sure what you mean by mass or charge

bronze jetty
#

We never measured spin directly
We just did experiments and then decided to mark some signs as spin and stuff
It’s a concept which plays an important role in our systems but it’s not all about magnetic moment

storm sage
#

I'm not a physicist honestly

#

As far as I can tell, is doing experiments to measure its quantity not measuring it directly?

bronze jetty
#

QM is a predictive theory
It’s formalism tells you probable answers
But it doesn’t tell u how it becomes like that

storm sage
#

I'm a bit confused about the distinction you're drawing

storm sage
#

I'm just confused in general now

languid marten
#

Ahh I mean you said seeing spin physically as intrinsic magnetic moment, so isn't it like seeing charge as a intrinsic physical qt

storm sage
#

Oh to provide a bit more context, I was objecting to the idea that physicists should just sit down and compute things and not ascribe physical meaning to the computations

#

And Heterotic gave spin as an example of something where that wouldn't work

storm sage
#

What

bronze jetty
#

Physicists are not calculators

#

No

#

Would u let me explain ?

storm sage
#

I'm so confused I said "There is a physical interpretation to the mathematics and I think not trying to give it is misguided" and you responded with spin as a counterexample

#

Yes please do, what is your position?

bronze jetty
#

Physics theories are 2 kind
Descriptive and predictive
Descriptive theory tells you reasons of an event and phenomena

#

Predictive theory says in a gathered instrument and initial condition, what results would be achieved

#

Now, based on my argument, quantum mechanics is a predictive theory
U have a superposition of states at first glance which doesn’t have a physical meaning in classical mechanics
Then u measure and show up with only one result

#

With the probability calculated from superposition

#

But standard quantum mechanics doesn’t tell us how it happens

storm sage
#

Okay yes I agree with all of that

#

What in your opinion would be a descriptive theory then?

bronze jetty
#

Newtonian mechanics

storm sage
#

See that's what I don't understand, how is that more descriptive than quantum mechanics?

#

It also tells you what data you expect to gather from any given experiment

bronze jetty
#

May I answer?

#

In newton formalism we write : F=ma

#

Here , m is a quantity which we measure it and it plays a role and it’s character of system

#

We call it mass

#

What the fuck is mass?

#

A quantity of matter which we can measure and fits in newton equation

rocky shuttle
#

We never measured the mass directly
We just did experiments and then decided to mark some signs as mass and stuff

bronze jetty
#

Now in quantum mechanics the main role is pleated by state vector

storm sage
#

So what is the distinction you're drawing here between mass in newtonian mechanics and spin in quantum mechanics

#

I'm still rather confused sorry

bronze jetty
#

Mass is inside of the matter and independent of human observation

#

Spin and other shits are called “observables”

#

It means you have to observe it to say a quantity for that

rocky shuttle
#

relativistic mass go brr

storm sage
#

How do you know that something like mass is independent of human observation and something like spin depends on it?

#

I don't see where that came from

#

Couldn't it just be that mass is a convenient quantity to track everything and it doesn't "exist" independent of human observation, whatever that may mean?

bronze jetty
rocky shuttle
#

Newtonian mechanics is also only accurate in a non-relativistic, non-quantum regime of physics, so it does not describe the "true" state of matter either

storm sage
#

Isn't it also true that spin stays the same under certain conditions? Is this like a statement about the conditions under which something stays constant

#

I mean even your definition of mass earlier relied on human measurement

#

Which means that it can't be independent of human measurement under that definition

bronze jetty
#

Mass was an example only from classical mechanics

storm sage
#

Right I know, but you presented it as an example of how newtonian mechanics is fundamentally different from quantum mechanics right?

#

Your claim is that one is descriptive and that one is predictive

#

And I'm saying I don't see the distinction you're drawing

bronze jetty
#

Fundamental difference is depending in human in quantum mechanics

storm sage
#

What, is your claim not that Newtonian mechanics is descriptive and that quantum mechanics is predictive and that those two things (descriptive and predictive) are different?

#

I'm just confirming what you said earlier to see if you are still of the same opinion

bronze jetty
#

In classical mechanics it’s supposed that systems have definite quantities
U just don’t know them
In quantum mechanics, u can’t tell there’s a quantity before measuring

#

The only thing u can do is prediction of results

storm sage
#

Heterotic can you answer whether or not what I said is still your opinion or not

neat lintel
#

QM from a non physicist's perspective is always baloney talk

bronze jetty
#

In Newtonian mechanics if u know the exact conditions, u can realize all the past of system
But it’s not like that in quantum mechanics

storm sage
#

I'm trying to understand what your claim is and it's frustrating when I can't even figure out what claim you are making, never mind the validity

#

Is it your claim that Newtonian mechanics is descriptive and that QM is predictive and that descriptive and predictive are fundamentally different types of theories

rocky shuttle
#

React to one pls

bronze jetty
#

Claim:
Difference of quantum mechanics and other fields of physics is dependence of results on human measurements.
quantum mechanics predicts answers but doesn’t describe the past of the system

#

While in classical mechanics it’s possible

storm sage
#

Okay so I think you've changed from descriptive vs predictive to "is the theory deterministic?" i.e. can you predict the future precisely given perfect knowledge of the past?

bronze jetty
#

We can’t afford a clear picture of quantum system before measuring an observable

storm sage
#

Is that the distinction you are making between Newtonian mechanics and QM

neat lintel
bronze jetty
#

No
I don’t talk about determination argument
Although it’s near to thing I’m talking

neat lintel
#

which doesn't seem related to determinism

storm sage
#

So you're saying that the difference between the two is that classical mechanics is reversible while QM isn't?

#

i.e. you can know the past from a present observation

bronze jetty
#

Third time :
Difference between quantum mechanics and classical mechanics is dependence of results on human and experimenter

storm sage
#

Okay so you are saying that quantum mechanical observables "exist" (whatever that means) do not exist independently of an observer while classical mechanical observables do "exist" independently of an observer

#

And that's the fundamental difference between the two that you are drawing

bronze jetty
storm sage
#

How is it just now a philosophical argument, the argument hasn't changed at all

#

😭

#

I've just been asking clarifying questions about your claim

bronze jetty
#

May i ask sth?

storm sage
#

Sure

bronze jetty
#

U can use reduction method in classical mechanics
Right?

#

U can’t do it in quantum mechanics

rocky shuttle
#

What's that?

bronze jetty
#

U divide system to smaller parts
Investigate each part lonely and finally stick all of them together
Like simple questions of classical mechanics

storm sage
#

No you can't because every particle potentially influences each other

#

For example an n-body problem

bronze jetty
#

All the classical physicists do it every day

storm sage
#

Huh

bronze jetty
#

How ever

#

In classical mechanics u measure 2 different quantities like X,P

#

Measuring x doesn’t violate p

#

But it happens in quantum mechanics

#

And measuring process changes the quantity

#

Measuring process in classical mechanics won’t violate the system characteristics

#

But in quantum mechanics it happens

storm sage
#

How do you measure the speed of something in classical mechanics without changing the speed

#

I'm so confused

bronze jetty
#

U set 2 locations and measure time of travel between 2 locations

#

Speed is distance divided to time

#

U even don’t touch it

storm sage
#

Yes but you see that measuring the location of something requires affecting it in some way?

#

Even in Newtonian mechanics

bronze jetty
#

No it’s ok

storm sage
#

What

#

How do you propose to measure something without affecting it

bronze jetty
#

Let’s tell it in another way

storm sage
#

Okay with all due respect I can't continue this conversation any longer, as the goalposts keep changing

bronze jetty
#

But in quantum mechanics when u measure location again, u get completely another value

#

Here we claim that measuring speed cleaned information of location

#

Like Estern-Gerlach experiments on spins

storm sage
#

I understand the quantum mechanics here, but I don't wish to continue this argument as I can see it won't get anywhere

bronze jetty
#

Maybe it’s because of my weakness in English

#

But I can tell some reference

#

#

At least from my understanding of Newtonian mechanics, this means that the particle changes its state slightly

untold sage
#

Newton probably didn't care about such things at the time

storm sage
#

Newton thought that was light was a particle

#

So eh I guess not quite sure

steep basin
#

yall know what math means?

zealous garden
#

Mass or no mass, the photon has energy and momentum content, which is transferred when it is absorbed

#

Likewise a photon emitted must take its energy and momentum from something

#

I don't actually know physics though

flat harbor
#

nondeterministism and uncertainty are different concepts

#

"particles are knocked around by electrons in observation" does not imply anything about the determinism of the theory

flat harbor
#

the idea abt "low energy light not measuring position" and "high energy light not measuring momentum" is a reason that contributes to the uncertainty of position and momentum

#

but not its lower bound, which exists in quantum mechanics but not in classical

#

oh yea and qmech is deterministic under time evolution and the indeterminism only rly matters in wave function collapse

newtonian bullshit like force is change in momentum doesn't hold as applied to solar sails* on the face of it until you get into the bending of spacetime and mass-energy equivalence

#

and then it's resting on non-newtonian bases

#

I actually stopped trying to comprehend it because the stack exchange discussions on it tend to use notation that is beyond me, and the verbal expressions of it I always find unsatisfying

#

I am incapable of being a physicist imo

anyone who knows english speaking etiquette well
if a professor sends a reply to a personal email and ends it off with
best,
name
does he want to be called by that name without the "prof." in the next email? or should one still use "prof."
also: is it rude to still use prof. afterwards or not using it?

surreal sapphire
#

what is name?

#

just the first name or first and last name?

#

if the former, thats most often an indication to use just the first name

#

if the latter, you should address by lastname

whether prof is important in this case depends on the person, you cant tell from an email

it certainly doesnt hurt to use it

Geometrically what we’re doing here (for the z_k’s)

#

Is just taking one root

#

Then rotating it to get the next root

#

Then rotating again to get the next

#

And so on

And the reason this works is since we’re multiplying by the roots of unity, which have magnitude 1, so they’re a pure rotation

On Khan Academy it says in order Algebra 1 > High School Geometry > Algebra 2. I'm not sure if the order is supposed to be done in order ideally after the grade stuff but, is that going to be fine? am I going to understand enough of the high school geometry after algebra 1? or should I do: Algebra 1 > Algebra 2 > High school geometry...

#

?

solid snow
#

either is fine

neat lintel
#

Also, I assume it's better to do college algebra before precalculus?

solid snow
#

college algebra by and large does not mean anything

#

i.e 'no'

neat lintel
#

I'm just gonna follow the order per the website and hope that's okay.. unless someone can advise otherwise.

#

Goal is to learn up to calculus then stats though.

#

Trying ensure I cover concepts prior to them being introduced out of the blue then I get stuck and have to jump ahead then back etc.

@flat hazel this is how i do it in my head
$$6 + 17 + 2 $$
$$ 6 + (17+2)$$
$$6+19$$
$$Note: n + 9 = n + 10 -1$$
$$10 + 6 + 9$$
$$10 +16 -1$$
$$10+15$$
$$25$$

flat hazel
#

Well

neat lintel
#

the other way i would do it would be
$$6 + 17 + 2$$
$$8 + 17$$
$$(8-x) + (17+x)$$
Where x is a number that turns 17 into a factor of 10
$$\mod(10,17+x)=0$$
$$x=3$$
$$5+20$$
$$25$$

learning math again is fun like I kind of expected it to be. It feels silly having to learn all the things I didn't learn in high school but I still love it.

RN I'm learning all the math I didn't learn in school in preparation for entering college for a STEM degree, and I just finished reviewing the Level 3 review exam which is listed as Geometry and Algebra 1.

its safe to say that the thing we learn from psychology is everything in our brain is super complex yet easily worked through based off of past accounts from the first point of memory to last point of memory, and then you figure out that dwelling is bad so don't make people dwell, so once you make the patient stop dwelling you make them stop self loathing once you make them stop self loathing they realize they had the potential within themselves to be super strong the entire time, patient then realizes they never needed psychology and repeat

and then they know what to do to "fix" it

I am not denying the fact that mental health is indeed a spectrum however

#

but i learnt the fact and philosophical idea through myself that it was all in my head, that i was stonewalling, and that since i was stonewalling and refused any point of view but my own delusion it kept me in that mindset

#

and then i found out the truthful fact of "Let your past not affect your Future" Many Many philosophies believei n this. "We are the ones who refuse to build our own building blocks"

#

Therapy always ends with "I never needed that" if we build a true stoic resilience to our own issues

#

which as humans we are ALL capable of

#

if the greeks could fight in a Complex Hoplite Palisade or Hoplite long Spear Formation, and if we can evolve from 0bc to 2000 ad we are smart enough to fix everything already

we have the tools

#

If the problem is you, I suppose therapy is super helpful

The problem being me means therapists cannot fix it

that means I must fix it

we must be the resilency which moves mountains

and be strong for ourselves and others, like a paragon of virtue

#

Well ok, classic stoicism?

#

Although virtue is like common among many philosophies

urban frigate
#

All a therapist teaches is what I have said here, just in a much longer period, and more with dwelling and making people feel worse temporarily, then solving it with a chemical concoction?

#

"because drugs are the way to fix a human soul" - not one man

#

if we think into our past, to day 1, when we learnt to count to 5, were we not happy? joyful full of innocence and life?

#

are we not also capable of still being that, without people telling us we cannot be?

#

we are simply our own brick wall in the way

#

we are the thing preventing us from self love in that situation

it is like, salvation is right across the room, and all we have to do, is with self awareness and kindness extend our arm

to ourself.

A charged particle (mass = m, charge = q) is placed at the centre of a circular region containing a magnetic field. The magnetic field is given as a function of radial distance only and is directed perpendicular to the plane of the circle. The total magnetic flux through the circle is zero. The particle is given a radial impulse. If the particle leaves the circular region, then at the instant it leaves comment on the particle's velocity (i.e. radial, tangential, etc.)

#

do u wanna summarise which points in this problem u think are most relevant hints to solving it

marble willow
#

i have no clue but if I were to guess I'd do so
they went out of their way to say the magnitude of magnetic field has only radial distance dependence maybe that

flat harbor
#

yes that is very important

#

imo theres a few more and theyre closely related

marble willow
#

magnetic flux thingy?

flat harbor
#

ye

marble willow
#

i brutally ignored that one because i couldn't make use of it

flat harbor
#

theyre all important, theres no red herrings in this problem

marble willow
#

i see

#

how would i proceed?

flat harbor
#

well first ud ask what the magnetic field does to this particle

marble willow
#

a radial velocity means tangential force and a tangential force means a tangential velocity which in turn means a radial force and so on

flat harbor
#

ye and this makes the problem pretty complicated

#

have u done any orbit stuff before

marble willow
#

what do you mean

#

ive done elliptical orbits etc

#

if that holds relevance

flat harbor
#

yeey

#

in those problems u can convert a 2d problem into a radial one bc its a symmetric system right

marble willow
#

i have had instances of converting a 2d motion into a radial motion, yes

flat harbor
#

if u culd do this for this problem do u think u culd apply the zero flux condition

marble willow
#

i could try

flat harbor
#

yems give it some thought

marble willow
#

actually

flat harbor
#

ill think abt it while writing stuff done too

marble willow
#

i can't

#

the flux doesn't relate with the velocity

#

so a radial motion wouldn't do any better

#

or would it
