Relativity 4 Engineers
I get a lot of notices and one that recently came my way was the announcement that the website Engineering.com has begun allowing their members to have blogs through their site. On reviewing the new blogs, I think it has a bit of work needed ... it's an "open blog community" where finding relevant information is a bit of a chore. If you have an interest in engineering, though, there are definitely people out there dispensing useful information and it's probably worth checking out.
One blogger which caught my eye was Burt Jordaan's post on The "Twin Paradox", a complex hypothetical example of Einstein's theory of relativity in action that I have not yet had a chance to cover on this site.
But it seems that Mr. Jordaan does not end there. He has an entire ebook, Relativity-4-Engineers, with a lot of great material also posted to the website. I haven't read the ebook yet myself, but, as you can probably tell, I'm fairly impressed with what I've seen so far.

I RECALL READINT THAT BLACKHOLES SWALLOW UP ENTIRE GALAXIES WITHOUT LEAVING A TRACE THUS DEFYIBG THEKNOWN LAWS OF THE PRESERVATION OF MATTER AND ENERGY.wELL, i DO NOT THINK THIS IS POSSIBLE. iT IS MOST LIKELY THE MATTER-ENERGY IS CONVERTED INTO DARK MATTER AND DDARK ENERGY BUT WITHOUT ADEQUATE MEASUREING DEVICES WHO CAN REALLY SAY THAT THE GALACTIC MATERIEL VANISHES WITHOUT A TRACE?
I don’t know where you read that black holes can swallow whole galaxies, but that has certainly not been observed.
Black holes “swallow” material (stars, dust, gas) orbiting in their immediate vicinity. Such matter disappears from view, but the mass of the black hole grows by the same amount that it swallowed, so matter and energy is conserved.
Matter that orbits at a “safe” distance cannot really fall into the black hole, due to orbital mechanics.

Kepler (demolish) Vs Einstein’s
Ending Einstein’s space jail of time in 2009 that led to fraud Symbol E=mc²
Areal velocity is constant: r² θ’ =h Kepler’s Law
h = 2π a b/T; b=a√ (1-ε²); a = mean distance value; ε = eccentricity
r² θ’= h = S² w’
S = r exp (ỉ wt); h = [r² Exp (2iwt)] w’=r²θ’
w’ = (θ’) exp [-2(i wt)]
w’= (h/r²) [cosine 2(wt) - ỉ sine 2(wt)] = (h/r²) [1- 2sine² (wt) - ỉ sin 2(wt)]
w’ = w’(x) + ỉ w’(y) ; w’(x) = (h/r²) [ 1- 2sine² (wt)]
Δ w’= w’(x) – (h/r²) = – 2(h/r²) sine² (wt) = – 2(h/r²) (v/c) ² v/c=sine wt
(h/ r²)(Perihelion/Periastron)= [2πa.a√ (1-ε²)]/Ta² (1-ε) ²= [2π√ (1-ε²)]/T (1-ε) ²
Δ w’ = [w'(x) – h/r²] = -4π {[√ (1-ε²)]/T (1-ε) ²} (v/c) ² radian per second
{x [180/π;degrees]x[100years=36526days;century]x[3600;seconds in degree]
Δ w” = (-720×36526x3600/T) {[√ (1-ε²]/(1-ε)²} (v/c)² seconds of arc per century
This Kepler’s Equation solves all the problems Einstein and all physicists could not solve

Quantum = Newton x Visual Effects
Quantum – Newton = Relativistic = Optical Illusions
E (Energy by definition) = mv²/2 = mc²/2; if v = c
m = mass; v= speed; c= light speed; w= angular velocity; t= time
S = r Exp (ì w t) = r [cos (wt) + ì sin (wt)] Visual effects
P = visual velocity = change of visual location
P = d S/d t = v Exp (ì w t) + ì w r Exp (ì w t)
= (v + ì w r) Exp (ì w t) = v (1 + ì) Exp (ì w t) = visual speed; v = wr
E (visual energy= what you see in lab) = m p²/2; replace v by p in E = mv²/2
= m p²/2 = m v²/2 (1 + ì) ² Exp (2ì wt)
= mv²/2 (2ì) [cosine (2wt) + ì sine (2wt)]
=ì mv² [1 - 2 sine² (wt) + 2 ì sine (wt) cosine (wt)];v = speed; c = light speed
wt = π/2
E (visual) = ìmv² (1 – 2 + 0)
E (visual) = -ì mc² ≡ mc² (absolute value;-ì = negative complex unit) If v = c
w t = π/4
E (visual) = imv² [1-1 +ỉ] =-mc²; v = c
wt =-π/4+ỉln2/2; 2ỉ wt=-ỉπ/2 – ln2
Exp (2i wt) = Exp [-ỉπ/2] Exp [ln(1/2)]=[-ỉ (1/2)]
E (visual) = imv² (-ỉ/2) =1/2mc² v = c
Conclusion: E = mc² is the visual Illusion of E = mc²/2 joenahhas1958@yahoo.com. All rights reserved.
PS: In case of E=mc² claims to be rest energy claims then
E=1/2m (m v + m’ r) ² = (1/2m) (m’ r) ²; v = 0
E = (1/2m) (mc) ²; m’ r =mc
E=mc²/2

Visual Effects and the confusions of “Modern” physics
r ——— Light sensing of moving objects ——- S
Actual object—– Light ——— Visual object
r – ——-cosine (wt) + i sine (wt) – S = r [cosine (wt) + i sine (wt)]
Newton– Kepler’s time visual effects — Time dependent Newton
Particle ————– Visual effects ——————– Wave
Line of Sight: r cosine wt
r ——————- r cosine (wt) line of sight light aberrations
A moving object with velocity v will be visualized by
light sensing through an angle (wt);w = constant and t= time
Also, sine wt = v/c; cosine wt = √ [1-sine² (wt) = √ [1-(v/c) ²]
A visual object moving with velocity v will be seen as S
S = r [cosine (wt) + i sine (wt)] = r Exp [i wt]; Exp = Exponential
S = r [√ [1-(v/c) ²] + ỉ (v/c)] = S x + i S y
S x = Visual along the line of sight = r [√ [1-(v/c) ²]
This Equation is special relativity length contraction formula
And it is just the visual effects caused by light aberrations of a
moving object along the line of sight.
In a right angled velocity triangle A B C: Angle A = wt; angle B = 90°; Angle C = 90° -wt
AB = hypotenuse = c; BC = opposite = v; CA= adjacent = √ [1-(v/c) ²]
