That doesn't compute either.


x^² + y^² + z^² = c^²t^² Einstein/Minkowski/Newton/Pythagoras
xi^² + eta^² + zeta^² = c^²tau^² Einstein/Minkowski

tau = (t-vx/c²)/sqrt(1-v²/c²) Einstein
tau = (t-uy/c²)/sqrt(1-u²/c²) Androcles
tau = (t-wz/c²)/sqrt(1-w²/c²) Androcles
xi = (x-vt)/sqrt(1-v²/c²) Einstein
eta = (y-ut)/sqrt(1-u²/c²) Androcles
zeta= (z-wt)/sqrt(1-w²/c²) Androcles

(Unless you have three time axes, t1, t2, t3 and a transformation to
tau1,tau2, tau3.)

sqrt(-1) is only mystical to those that don't understand complex numbers
are vectors and time is not a vector, it has no additive inverse.
Charlatans have used math as a weapon for extortion throughout history,
predicting eclipses and extending that to predicting the future, fortune
telling.
Check your horoscope. Modern day charlatans are no different, the goal
is still the same. They want your money. sqrt(-1) is a useful mathematical
tool, but like any ploughshare it can be beaten into a sword; pillage and
rape
being the objective of agression.

The top down approach is less effective than the bottom up approach.
Riemann looked at Euclid's postulates and questioned them. He started
at the root and built his own geometry. Einstein copied that idea, but
his three "postulates" are incompatible.
Two he openly declares as postulates, the third he disguised as a
nonsense "definition".

That's backwards, my friend. GR is built on SR and SR is built
on three postulates, only one of which can be described as
self-evident and a true postulate, untestable and incontestable.

"Take, for example, the reciprocal electrodynamic action of a
magnet and a conductor. The observable phenomenon here depends
only on the
________relative_ motion___________
of the conductor and the magnet" -- Einstein.

That's the postulate. "Relative_motion". You know what it means,
Einstein cannot define it, he can only give an example and it is not
to be disputed.
Only the ignorant fool would do so, and that's what Einstein does.
He is effectively saying when A meets B, B doesn't yet meet A because
B has a different time to A.

By definition fiction is always "suspension of disbelief", the
library shelves are loaded with fiction. Fiction is by far the
leading source of entertainment, outstripping high wire and trapeze
circus acts, Eval Kneivel motorcycle jumps or walking on the Moon.
Kids today are skeptical that anyone ever did walk on the Moon,
yet they swallow Einstein's crap as though it were gospel truth,
and that's just what it is -- God's spell -- pure fucking magical
mysticism.
I'm a magician too. Most engineers are. The Queen, now 80, said
"Mirror, mirror, on the wall, who's the fairest of them all?"
The computer uses the internet to access a web cam looking
in at a broad shacked up with seven short guys and says
"Snow White, you stupid old bag, she's getting seven times
more prick than you ever did, along with herpes simplex and
callouses on her arse".
If you don't know how to make it work then it's magic, else it's reality.
