I studied in high school that there are four types of measuring quantities
1)Scalar
2)Vector
3)Phasor
4)Tensor
I studied about Scalar and vector in great detail,but,i did not get to know about Phasor and Tensor.

um a tensor is a type of matrix

- hba

Hmm.
What about phasor ?

- anonymous

tensor- how i get before a test
phasor- star trek weapon can be turned up to lethal or stunning strength
your welcome <3

your'e*

- anonymous

you're* :)

- hba

ty.

- UnkleRhaukus

i dont know about phasors, but i have also heard of spinors

- hba

Hmm.Thanks a lot @UnkleRhaukus :)

- UnkleRhaukus

wikipedia tells me that a phasor is just a sinusoid

- hba

Just a sinusoid ?

- hba

Lemme check.

- UnkleRhaukus

i would like to know the difference between a spinor and a tensor (they are some kinda matrix) , but my studies havent brought me to that level yet

- hba

a phasor or sinor is some sort of a sinusoid.

- hba

I don't know what Spinor is though.

- UnkleRhaukus

hmm what about Twistors?

- hba

Well,I have just completed high school,So you cannot expect that from me lol :P
Spinors,twistors and quaternion are something i have not studied yet :(

- UnkleRhaukus

they look a bit scary to me ,
but i aim to one day have a deep understanding of these concepts ,
one day

- hba

I also hope to have an understanding about them one day :)
@Callisto
Can you help us ?

- Callisto

@hba Note that I'm just at the same level as you. How am I supposed to know that?

- hba

@Callisto
I have not joined Uni yet and you are done with a whole semster.

- hba

semester*

- Callisto

I'm sorry. I took the calculus course in the first semester, haven't taken the linear algebra yet.

@hartnn Lifesaver :'(

@hartnn
Tell me about Phasor and tensor((they are some kinda matrix) ?

- hartnn

phasor is just a phase vector,
like \(A \sin (\omega \theta)\) is a phasor,
one which has amplitude, frequency and phase.

- hartnn

don't know much about tensors.....

- hartnn

i meant \(A \sin (\omega t +\theta)\)
as phasor....

- hba

Um,I read something like this from Wiki.
Can you tell me something more ?

- hartnn

i can't tell you more than wiki :P
this was never taught to me...

- hba

I will just go to my professor and ask him about this,
Thanks a lot for helping.

- hba

@ajprincess Here

- ajprincess

Really sorry @hba. I too have no idea:( Guess they will be teachng me these in my second yr.

- anonymous

All the above three quantities are one and same..in the sense all represents physical quantities

- hba

@experimentX
Can you help ?

- experimentX

scalar is a tensor of rank zero

- experimentX

vector is a tensor of rank 1
here is a better explanation

- hba

What about Phasor ?

- experimentX

I am not sure about phasor, at least it's not a vector according to wikipedia

- hba

Hmm,Thanks a lot :)

- experimentX

sorry I don't have much experience in tensor calculus.

- hba

No worries c:

- UnkleRhaukus

so tensors are always square matrices?
