Jamela Mohamed and the Latest Tempest in the Muslim Teapot
Giving ground to activist instigation is exactly how Islamization spreads. You should think before letting your knee jerk.

Sound Credit Union's (Kent, Washington) refusal of service to Jamela Mohamed, a black Muslim female, on 5 May 2017, probably wasn't discrimination. There are suspicious gaps in the video at 0:36 and 1:03. We can't judge the events that happened at the credit union without knowing what happened during the missing blocks of time, as well as during the moments prior to the video's beginning. It's most likely that the bank enforced a sensible rule with some vigor and the rule-breaker's feelings got hurt.

Ms. Mohamed believes that she was the victim of illegal discrimination by Sound Credit Union because a white man wearing a baseball cap was served by a teller without incident, whereas she was challenged, first, over her hood and then over her Muslim hijab, which she went to her car to get and put on in place of the hood.

The rules against hoods might be enforced more strictly than those against small hats because a hood can hide the face from the side, while, say, a baseball cap does not. Facial recognition software uses the ears as well as the features on the front of the face, and whereas caps allow ears to be seen, the Muslim woman's hood does not.

Facial recognition software is an important tool used by law enforcement to identify criminals, such as bank robbers, so that they can be arrested and so that stolen property can be returned to its rightful owners. Any headwear, no matter what it is called, that inhibits the function of this software is, and ought to be, restricted by banks as a condition for their service.

If an exception is made for religious headwear, then it won't be long before robbers begin wearing it as a disguise, in order to increase their chances of getting away with the loot.

I do think that the woman on the bank staff was overly confrontational, though. But that might be because she knew that she was being "played" by a faux-polite political agitator, and wanted to make it clear that such tactics just aren't going to work.

Also, the crying scene that begins at 1:03 might be real... or it might be good acting.

Attentive viewers might have noticed that the woman donned her religious head covering ONLY to wear it into the bank. She hadn't minded showing her face to strangers in other public places. She used it to provoke the conflict that she lost... and then she starting crying about it... while not wearing her ever-so-important hijab any more.

Having said all that, it's necessary to point out that this video only documents parts of the woman's second entry into the bank. We aren't being shown, in this video, what she was wearing during her first visit, when presumably she was told that whatever she had been wearing then was contrary to the bank's rules.

Finally, there is one other possibility, though it is a little strange. The aggressive bank officer and the Muslim woman might have been in collusion with respect to the entire scene.

What makes me think so? Well, in real confrontation situations, it seldom happens that all the actors perform their parts in a picture-perfect manner.

The ostensible good guys usually bark back in a way that viewers might consider rude or provocative. They, however, incorrectly believe that they are conveying righteous indignation.

The ostensible bad guys usually don't come across like Genghis Khan. After all, even a hateful person likes to have a positive public image.

The behaviors of the two principle actors in the video play out their roles as they might do in a television drama. (I'd say "a poor quality television drama," but that would be redundant.) And so there is a possibility that this whole scene is contrived, with a bank officer playing a major part in a scripted sequence of events.

It's just something to keep in mind.

When will the Andromeda galaxy be only 200,000 light years from the Milky Way galaxy?
The Andromeda galaxy and the Milky Way galaxy are presently separated by 2.54e+6 light years, which is the same as

r₁ = 2.40303e+22 meters

The mass of the Andromeda galaxy is 1.5e+12 solar masses. The mass of the Milky Way galaxy is 8.0e+11 solar masses. One solar mass is 1.98855e+30 kilograms. The combined mass of the two galaxies is

M = 4.57367e+42 kilograms

The gravitational constant is

G = 6.67408e-11 m³ kg⁻¹ sec⁻²

The gravitational parameter of the two galaxies' mass is

GM = 3.05250e+32 m³ sec⁻²

The galaxies are presently moving toward each other, having a radial a speed of

v₁ = −110000 m/s

How much time will elapse between the present and the moment the two galaxies are separated by a distance of 200,000 light years? How fast will the two galaxies be moving with respect to each other when their separation has been reduced to 200,000 light years?

The distance that would have separated the Andromeda Galaxy from the Milky Way Galaxy, if we were to trace it backwards in time to the point of mutual rest, is found from

d = r₀ = [1/r₁ − v₁²/(2GM)]⁻¹

d = 4.58834e+22 meters

If two bodies having a total mass M are initially at rest and separated by a distance d, the time to fall until the separation is r, such that r is less than d, is found by integrating a differential form of the Vis Viva equation:

v = √[GM(2/r−1/a)]

Since the apoapsis of a plunge orbit is twice its semimajor axis,

a = d/2

v = √[2GM(1/r−1/d)]

Since all the motion in a plunge orbit is radial (i.e., there is no transverse component),

∂r/∂t = √[2GM(1/r−1/d)]

We derive an ordinary, non-linear differential equation with variables separable:

∂t = ∂r / √[2GM(1/r−1/d)]

t−t₀ = √[d/(2GM)] ∫ ∂r/√(d/r−1)

A substitution,

u = √(d/r−1)

∂u/∂r = −½ d r⁻²/√(d/r−1)

So that,

r = d/(u²+1)

∂r = (−2d) u [∂u/(u²+1)²]


t−t₀ = −2d √[d/(2GM)] ∫ ∂u/(u²+1)²

Integral form solution (CRC Standard Mathematical Tables, 32nd edition, page 296, No.48):

∫ ∂x/(x²±c²)ⁿ = {1/[2c²(n−1)]} { x/(x²±c²)ⁿ⁻¹ + (2n−3) ∫ ∂x/(x²±c²)ⁿ⁻¹ }

In which x=u, c²=1, n=2, and the "plus" case is taken.

∫ ∂u/(u²+1)² = {1/[(2)(1)(2−1)]} { u/(u²+1)²⁻¹ + (4−3) ∫ ∂u/(u²+1)²⁻¹ }

∫ ∂u/(u²+1)² = ½ u/(u²+1) + ½ ∫ ∂u/(u²+1)

t−t₀ = −2d √[d/(2GM)] { ½ u/(u²+1) + ½ ∫ ∂u/(u²+1) }

t−t₀ = −d √[d/(2GM)] { u/(u²+1) + ∫ ∂u/(u²+1) }

∫ ∂u/(u²+1) = arctan u

With the arctan function returning radian values, of course.

t−t₀ = −d √[d/(2GM)] { u/(u²+1) + arctan u }

t−t₀ = −d √[d/(2GM)] { √(d/r−1)/[(d/r−1)+1] + arctan √(d/r−1) }

t−t₀ = −√[d/(2GM)] { √(rd−r²) + d arctan √(d/r−1) }

The minus sign indicates that the distance decreases with time. But we already know that and we like our times to be positive, so we just remove the minus sign, and

t−t₀ = √[d/(2GM)] { √(rd−r²) + d arctan √(d/r−1) }

As an aside, if r«d then t−t₀ ≈ π √[d³/(8GM)]

The time to fall from where the galaxies were when they were at mutual rest (t=t₀) to where they are at present (t=t₁) is

t₁−t₀ = √[d/(2GM)] { √(r₁d−r₁²) + d arctan[√(d/r₁−1)] }

t₁−t₀ = 5.01638e+17 sec

The time to fall from where the galaxies were when they were at mutual rest (t=t₀) to the moment (t=t₂) when their separation is r₂, where

r₂ = 200000 light years = 1.89215e+21 meters


t₂−t₀ = √[d/(2GM)] { √(r₂d−r₂²) + d arctan[√(d/r₂−1)] }

t₂−t₀ = 6.22578e+17 sec

The difference is the amount of time needed for the separation between the galaxies to close from r₁ to r₂.

t₂−t₁ = (t₂−t₀)−(t₁−t₀)

t₂−t₁ = 1.20941e+17 sec

t₂−t₁ = 3.83238e+9 years

At t₂ the radial velocity will be

v₂ = −556187 m/s

And from there it will be about another 80 million years until mid-collision.

Since the plunge orbit for Andromeda and Milky Way has a quarter-period of 19.8 billion years, the coming galaxy collision is the first that has ever occurred between them. The universe isn't old enough even for one quarter-period to have completed, so the galaxies must have had some approach speed from the start.

Indeed, a little more math will tell you that when the Andromeda Galaxy (the younger of the two) formed nine billion years ago, the centers of mass of the two galaxies were 3,896,390 light years apart and already moving toward each other at 57.06 km/s.

The United States cannot afford its welfare parasites.
When you combine federal and state expenditures for welfare programs, the total comes to about $1.2 trillion per year. That's a lot of money.

If we were to imagine that working Americans paid an equal amount to cover that welfare cost, it would amount to $10,000 from each working citizen. Think about that.

Now, the US government doesn't get that $10,000 from us immediately. No, it borrows from the Federal Reserve banks what it then uses to shovel benefits at the welfare parasites. It'll get around to sending people the bill, though. And it'll have interest charges added to it.

For black and Hispanic families, welfare is the norm. The black and Hispanic families that are NOT on welfare are exceptions to the general trend.

It is no longer true that most welfare recipients are white. According to the latest figures, less than half of people on welfare are white, despite the fact that whites still form a majority of the US population.

Welfare is a way of life for non-whites. They are leeches, parasites, on the productive labor of whites. The more of them there are, the harder life for us will be. And that will continue until life for us simply cannot go on at all.

Examples of Malevolent Jewish Activity Since the Late 1800s
And of the Historical Propaganda that is Meant to Conceal It

It should be no secret to any educated person that wars are usually instigated for financial reasons. The Armenian Genocide (1915), often blamed on Turkish nationalism, was actually triggered by the Rothschild banking family, through their agent, a Jew named Emanuel Curasso. He was part of the group that led the Young Turks, whose membership was a mixture of Muslims and Jews.

The Caspian and Black Sea Petroleum Company, founded by Alphonse Rothschild in 1883, extracted oil from fields near Baku, in Azerbaijan. This crude oil from Azerbaijan was shipped over the Caucasus Mountains by rail to a port city called Batumi, in what is today the FSU Republic of Georgia. It was shipped by sea through the Bosporus and Dardanelles waterways, to the Mediterranean Sea, and thence, up the Adriatic Sea, to Fiume. Fiume was the name of a Croatian port city that is now named Rijeka.

The petroleum products, significant among which was kerosene, processed at the Rothschild refineries at Fiume, were sold throughout central Europe and, secondarily, in the Middle East, in competition with similar products sold by the Rockefeller-owned Standard Oil Company.

The ethnic tension between the Turks and Armenians, which had been a regular feature of that region’s political life for a long time, posed a risk to the Rothschilds’ shipping, and a business cost was involved in keeping that risk to a minimum.

So, to increase their profits, the Rothschilds hatched a plan to overthrow the Turkish Sultan and exterminate the Armenian people. The former was accomplished in 1908 and had the additional benefit (to the Jews) of removing an impediment to the creation of a Jewish state in Palestine.

The latter was carried out beginning in April 1915.

The Wikipedia article on the Armenian Genocide contains some factual matter mixed with misdirection. It is reasonably accurate about what happened to the Armenians, but it is wrong about who the villains were and what their motivation was. The correct matter is information-candy embroidery, acting like a sweetener to induce the reader to accept the falsehoods as well.

The Wiki article on the Armenian Genocide sets the blame for it on “the Three Pashas” and uses proximity of mention to lead readers to infer that these Three Pashas were leaders of the Turkish nationalists. But no such thing is true. If you then read the Wiki article on “Three Pashas,” you will be told that they were members of “The Committee of Union and Progress,” which was the original name for a group that was afterward called the Young Turks.

Then, if you read Wikipedia's article on Mehmed Talaat Pasha, he is said to be the primary organizer of the Armenian Genocide, and he...

"...worked after hours as a Turkish language teacher in the Alliance Israelite School which served the Jewish community of Edirne. At the age of 21 he had a love affair with the daughter of the Jewish headmaster for whom he worked. He was ... charged with tampering with the official telegraph and arrested in 1893. He claimed that the message in question was to his girlfriend. The Jewish girl came forward to defend him. Sentenced to two years in jail, he was pardoned but exiled to Salonica as a postal clerk." — Wikipedia
What that probably means is Talaat was selected and groomed for his role in the Armenian Genocide because of his close connection with Jews in the infamous Jewish conspiracy organization, Alliance Israelite Universelle. He wasn't really exiled to Salonica, either. Salonica is where the Young Turks had recently been organized. So, rather than being exiled, Talaat was sent to Salonica to perform a very nasty job for the predatory Rothschilds.

The Young Turks were a group organized in Salonica, Macedonia, in 1890, by Emmanuel Curasso, an agent of the Jewish Rothschild family, to take over the reins of power in the Ottoman Empire, to reshape it politically, and to eliminate the Armenian population.

Nowhere does Wikipedia put all of the links between the Jewish founders of the Young Turks and the Armenian Genocide in the same article. Indeed, even if you gather up several related articles, there will be at least one missing link, such as the fact that the Three Pashas were part of a Jewish-organized and Jewish-led group that had two purposes that were rather important to Jews.

There are more reliable resources than Wikipedia on the subject of the Armenian Genocide, such as Little Armenia's Fact Sheet on the Armenian Genocide.

It is usually the case that what is left out of historical narratives is at least as important as what is included, in regard to enabling their readers to form accurate opinions and exercise sound judgment in putting historical lessons into political action. In 1908, when the Armenians first heard about the overthrow of the Sultan, they celebrated because, they thought, having anyone else in power must be a good thing. But that isn't the case, when the "anyone else" is the Jews.

Likewise, the Second World War began because Germany broke away from the Jewish banking houses, including the Rothschilds. These Jews had expected Hitler to place Germany in debt with loans from their banks as his means of bringing about Germany’s economic recovery, at least in the near-term. (Economic recoveries based upon usury contain an embedded financial time-bomb, which explodes when the interest on the accumulated national debt becomes unpayable.) Instead, Hitler found other means — including international barter and alternative financial systems in which the Jews didn’t have any usurious fingers in the pie.

This fact was well-understood at the time, and it was summarized by Viscount Lymington: “If we have a period of peace for only three years, the financial system of Messrs. Frankfurter, Warburg, and Baruch, and most of Wall Street, will topple of its own accord.” (Source: The New Pioneer, May 1939.)

That was the actual reason for the Second World War. Hitler was about to yank the Jewish vampire off the back of Western civilization, and that vampire did not want to be deprived of its prey. So it began a war to defend the parasitical status quo.

The invasion of Poland was a pretext. If it had been the real reason for the war, then the simultaneous invasion of Poland’s eastern half by the Soviet Union would have been just as objectionable as Germany’s invasion of Poland’s western half.

A third example of very nasty organized Jewish behavior is the causing of millions of deaths in Ukraine during the early 1930s by Lazar Kaganovich, a Jewish Soviet official who was told by Joseph Stalin to suppress Ukrainian nationalist aspirations. Stalin didn't care how Kaganovich did it, and the idea of starving the Ukrainians to death was the method that Kaganovich selected because, apparently, being a Jew, he wanted to kill a lot of Christians. Given the chance, he did.

How to Read a Planet
You are in an elliptical orbit in the equatorial plane of a certain planet. With simple instruments — a sextant, a laser ranger, and a stopwatch — you gather data from which you can calculate a whole lot of other stuff.

Dₑ₀ = apparent angular width of the planet equatorially at periapsis
Dₑ₁ = apparent angular width of the planet equatorially at apoapsis
Dᵨ₀ = apparent angular width of the planet polewise at periapsis
Dᵨ₁ = apparent angular width of the planet polewise at apoapsis
h₀ = altitude of periapsis above surface
P = period of orbit

G = 6.67408e-11 m³ kg⁻¹ sec⁻²
π = 3.1415926535897932384626433832795

e = eccentricity of orbit
Rₑ = equatorial radius of planet
r₀ = periapsis radius
a = semimajor axis of orbit
R = average radius of planet
V = geometric volume of planet
ρ = average density of planet
M = mass of planet
r₁ = apoapsis radius
v₀ = speed at periapsis, relative to planet's center
v₁ = speed at apoapsis, relative to planet's center
Rᵨ = polar radius of planet
f = oblateness of planet
g = surface gravity of planet, neglecting rotation
v = escape speed from planet's surface, neglecting air resistance

Derivation of equation to find the eccentricity of the observer's orbit.

Rₑ = r₀ sin(½Dₑ₀) = r₁ sin(½Dₑ₁)
r₀ = a(1−e)
r₁ = a(1+e)
a(1−e) sin(½Dₑ₀) = a(1+e) sin(½Dₑ₁)
sin(½Dₑ₀) − e sin(½Dₑ₀) = sin(½Dₑ₁) + e sin(½Dₑ₁)
e[sin(½Dₑ₁) + sin(½Dₑ₀)] = sin(½Dₑ₀) − sin(½Dₑ₁)

e = [sin(½Dₑ₀) − sin(½Dₑ₁)] / [sin(½Dₑ₀) + sin(½Dₑ₁)]

Derivation of equation to find the equatorial radius of the planet.

sin(½Dₑ₀) = Rₑ/r₀
r₀ = h₀+Rₑ
sin(½Dₑ₀) = Rₑ/(h₀+Rₑ)
h₀/Rₑ + 1 = 1/sin(½Dₑ₀)
h₀/Rₑ = 1/sin(½Dₑ₀) − 1

Rₑ = h₀ / {csc(½Dₑ₀) − 1}

The other stuff...

r₀ = h₀+Rₑ
a = r₀/(1−e)
R = Rₑ ∛{sin(½Dᵨ₀) / sin(½Dₑ₀)}
V = (4π/3)R³
ρ = 3πa³/(GP²R³)
M = ρV
r₁ = a(1+e)
v₀ = √[GM(2/r₀−1/a)]
v₁ = √[GM(2/r₁−1/a)]
Rᵨ = R³/Rₑ²
f = 1 − Rᵨ/Rₑ
g = GM/Rₑ²
v = √(2GM/Rₑ)

If you want to get the mass of the planet directly from the data, then do this:

M = [½π²h₀³/(GP²)] { [1 + sin(½Dₑ₀) csc(½Dₑ₁)] / [1−sin(½Dₑ₀)] }³

Monsanto's patented genes, the heirloom crops of the small farmer, and the rights of property
When the courts are corrupt, the trespasser is confused with the trespassed upon

It seems to me that the presumptive obligation for preventing the spread of patented genes belongs to the patent owner, not to the farmer next door who might regard the spread of someone else's genes into his heirloom crops to be a form of trespassing.

The small farmer has the more natural right to sue Monsanto than vice versa.

The reason that it is made to seem the other way around is a corruption of jurisprudence brought about by the unequal financial means of the litigant parties. Monsanto is rich. The small farmer is poor. And that's all that really matters in practice, so far as the court's decisions are concerned.

At the very least, if Monsanto is so very careless as to permit its patented genes to infect someone else's crops, then every court in the country should simply shrug its judicial shoulders and say:

"Too bad for you, Monsanto. That farmer did not steal your genes. The winds did it in what we once called a proverbial 'Act of God.' The farmer, having done no wrong, owes you nothing. You, having neglected due diligence in the security of your patent rights, are denied the redress sought by your suit."

Semimajor axis, eccentricity, and period from gravitational parameter, periapsis and apoapsis speeds
Jenab's Fireside Chats celebrates 10 years of helping undergraduate students of physics and astronomy cheat on their homework!

TODAY'S HOMEWORK QUESTION: If you know the mass of a star and an object’s speed at perihelion (closest approach to the star) and speed at aphelion (farthest point from the star), you can find the perihelion and aphelion distances. A particular comet has perihelion speed 8.3x10⁴ m/s and aphelion speed 6.8x10³ m/s as it orbits the Sun. (a) What are the closest and farthest distances from the star for this comet? What is the eccentricity of the orbit? (b) What is the expected orbital period of this comet?


v₁ = 83000 m/s
v₂ = 6800 m/s
GM = 1.3271244e+20 m³ sec⁻²

r₁ = a(1−e)
r₂ = a(1+e)
v₁ = √[GM(2/r₁−1/a)]
v₂ = √[GM(2/r₂−1/a)]

v₁ = √[(GM/a){2/(1−e)−1}]
v₂ = √[(GM/a)(2/(1+e)−1)]

v₁ = √{(GM/a)[(2−1+e)/(1−e)]}
v₂ = √{(GM/a)[(2−1−e)/(1+e)]}

v₁ = √{(GM/a)[(1+e)/(1−e)]}
v₂ = √{(GM/a)[(1−e)/(1+e)]}

(v₁/v₂)² = (1+e)²/(1−e)²

v₁/v₂ = (1+e)/(1−e)

(v₁/v₂)(1−e) = 1+e

(v₁/v₂)−e(v₁/v₂) = 1+e

e+e(v₁/v₂) = (v₁/v₂)−1

e[1+(v₁/v₂)] = (v₁/v₂)−1

Here's the equation to find the eccentricity.
e = [(v₁/v₂)−1] / [(v₁/v₂)+1]

e = 0.84855

v₁²−v₂² = (GM/a)[(1+e)/(1−e)] − (GM/a)[(1−e)/(1+e)]
v₁²−v₂² = (GM/a){[(1+e)/(1−e)] − [(1−e)/(1+e)]}

Here's the equation to find the semimajor axis.
a = GM { [(1+e)/(1−e)] − [(1−e)/(1+e)] } / (v₁²−v₂²)

Or, more directly,
a = GM (v₁/v₂ − v₂/v₁) / (v₁²−v₂²)

a = 2.3514e+11 meters = 1.5718 AU

r₁ = 3.5612e+10 meters
r₂ = 4.3467e+11 meters

Here is the equation to find the orbital period.
P = 2π √[a³/(GM)]

Or, more directly,
P = 2πGM [(v₁/v₂−v₂/v₁) / (v₁²−v₂²)]¹·⁵

P = 62188631 sec = 719.8 days

r₂ = the distance from the sun to the planet at time 2.
ρ₂ = the distance from Earth to the planet at time 2.

We must solve these two equations simultaneously for r₂ and ρ₂.

ρ₂ = K₀ − L₀/r₂³
r₂ = √(R๏₂² + q₂ρ₂ + ρ₂²)

This leads to an 8th degree polynomial in r₂.

F{r₂} = r₂⁸ − (R๏₂² + q₂K₀ + K₀²) r₂⁶ + L₀ (q₂ + 2K₀)r₂³ − L₀²
F{r₂} = 0

We will use Newton's method to get the answer.

Correction for Planetary Aberration (equations)

Light doesn't travel instantaneously. We must correct the initial times for the amount of time it took light to travel from the planet to our eyes. This is done only once, after the first approximation, but before the 2nd approximation. It will not be done between any other successive approximations.

For i = 1 to 3
tᵢ° = tᵢ − A ρᵢ

Where A is the time (in days) required for light to travel 1 astronomical unit.

τ₁ = k(t₃°−t₂°)

τ₃ = k(t₂°−t₁°)

Where k is the mean motion of Earth in radians per day.

From the state vector to the orbital elements (equations)

We remove the subscripts and wingdings from the position and velocity of the object at time t₂.

The distance of the object from the sun
r = √( x² + y² + z² )

The speed of the object, relative to the sun
V = √[ (Vx)² + (Vy)² + (Vz)² ]

The semimajor axis of the object's orbit around the sun
a = 1 / { 2/r − V²/(GM) }

The angular momentum, h, per unit mass (m²/sec), in the orbit

hx = y Vz − z Vy
hy = z Vx − x Vz
hz = x Vy − y Vx
h = √[ (hx)² + (hy)² + (hz)² ]

The eccentricity of the object's orbit around the sun
e = √[ 1 − h² / (GMa) ]

The inclination of the object's orbit, relative to the ecliptic
i = arccos( hz / h )

The longitude of the ascending node, Ω, of the object's orbit
Ω = Arctan ( hx , −hy )

The true anomaly, θ, of the object in the orbit at time t₂

cos θ = h²/(rGM) − 1
sin θ = h (x Vx + y Vy + z Vz) / (rGM)
θ = Arctan ( sin θ , cos θ )

Arctan is the two-dimensional arctangent function.

Argument of the perihelion, ω, of the orbit

cos ω'' = (x cos Ω + y sin Ω) / r
If sin i = 0 then sin ω'' = (y cos Ω − x sin Ω) / r
If sin i ≠ 0 then sin ω'' = z / (r sin i)
ω'' = Arctan( sin ω'' , cos ω'' )
ω' = ω'' − θ
If ω' ≥ 0 then ω = ω'
If ω' < 0 then ω = ω' + 2π

The eccentric anomaly, u, of the object in the orbit at time t₂

sin u = (r/a) sin θ / √(1−e²)
cos u = (r/a) cos θ + e
u = Arctan( sin u , cos u )

The mean anomaly, m, of the object in the orbit at time t₂
m = u − e sin u

Note: u must be entered in radians, and m will return in radians.

The period of the orbit, P, days
P = (π / 43200) √[ a³/(GM) ]

The mean motion, μ, in the orbit, radians per day
μ = 2π / P

The time of perihelion passage, T, of the object in the orbit, Julian Date
T = t − m/μ

Liberal protester committed an assault by fire at President Trump's inauguration
At Donald Trump's inauguration as the 45th President of the United States, a crowd of leftist protesters tried to block citizens from attending the event.

Among the liberal protesters was a woman who used a cigarette lighter to set on fire the hair of a female Trump supporter, while other liberals tried (unsuccessfully) to shield her attack from the view of a nearby camera.

After doing the deed, the perpetrator walked away through the crowd of leftists, none of whom tried to stop her. Although the liberals apologized afterward for the attack, their contrition did not extend to the point of holding the criminal for the police. Words are cheap.

The attacking woman bears a resemblance to Norma Zahory, an Administrative Coordinator who works with Communities In Schools in Washington, DC. The identification isn't conclusive, however. The attacker might be someone else. In fact, she probably is someone else. The woman who committed the crime looks more like a spic than a muzzie.

In fact, it might be worthwhile to find out who originally asserted that the woman in the blue-and-white hat was Norma Zahory. Why was he so sure about it? If he was. The Left is sneaky. It would not be above them to tag someone innocent in order to set up right-wingers who echo the false accusation for retaliatory legal actions.

The attacker is the woman wearing the blue and white hat, shown in the images below.
