|
| Do you know the difference between:
|
|    (80,0,0,16)
|
| and:
|
|    tau(80,0,0,16) ?

Yes.
|
| Define both.

(80,0,0,16) -A vector (as long as the 16 doesn't represent time, which 
is not a vector)
tau(80,0,0,16) - A single-valued function in four variables.

Examples of a vector:
 (0,0,0,0) + (60,0,0,20) =  (60,0,0,20)
  2*(40,0,0,8) = (80,0,0,16)

Examples of a phuckwit:  2*(60,0,0,20) = (80,0,0,16)
                                       2* (80,0,0,16) = (60,0,0,20)
Example of a single-valued function in 4 variables:
$20 = price(apple+orange+cherry,$16*retail/wholesale)

Do you know the difference between a phuckwit and a mathematician?
Define both. (Not possible for a phuckwit)

| Complete nonsense. The tau equation expresses a constraint between the
| stationary coordinates and one moving coordinate (namely, tau). 
| Without either of those systems there is no tau equation.

Stationary coordinates:
                Emission (0,0,0,0)
                Reflection (80,0,0,16)
                Reception (60,0,0,20)

Moving coordinates:
                Emission (0,0,0,0)
                Reflection (32,0,0,16)
                Reception (0,0,0,20)

You don't have a 32 anywhere.
So you don't have a tau equation <shrug>.
You ARE simply insane. You know practically zero about the subject and
yet you write... THIS?? Why even do you waste your time on this?

Time of the stationary system.

Locking you in a padded cell would be convenient shortcut.

| Nope. The point is that these times (16 seconds and 4 seconds) are in
| terms of the stationary clocks which is *not* what tau(...) are.

You don't have a point, you don't even have a neuron.
The point is that these prices ($16 and $4) are in terms of the
stationary wholesalers which is *not* what retail price(apple, orange) 
are.
I dont know how you survive in the real world.


| They

You don't have ANYTHING moving, not a 32 in sight.

Yes we do.
Stationary coordinates:
                Emission (0,0,0,0)
                Reflection (80,0,0,16)
                Reception (60,0,0,20)

Moving coordinates:
                Emission (0,0,0,0)
                Reflection (32,0,0,16)
                Reception (0,0,0,20)

You've left out
                Reflection (32,0,0,16)
You are simply insane. You know practically zero about the subject and
yet you write... THIS?? Why even do you waste your time on this?

|  tau(0,0,0,0) = 0
|  tau(60,0,0,20)) = 20 ?

Yes.

|
| No, what I think is:
|
|   tau(80,0,0,16) = 1/2*(tau(0,0,0,0) + tau(60,0,0,20))
|
| ...which is a *totally* different thing than "16 is half of 20 and 60
| is half of 80".

But you don't think. You are not capable of thinking.
You are simply insane.
Even Einstein would have said (and did say, effectively)
tau(32,0,0,16) = 1/2*(tau(0,0,0,0) + tau(60,0,0,20))

v(x,y,z,t) = x/t
c(x,y,z,t) = x/t

v(32,0,0,16) = 32/16 = 2.
c(80,0,0,16) = 80/16 = 5.
Your equation is the raving of a lunatic.
