There Are Riots In Iran And The Usual Suspects Are On It
There are a few riots in Iran and Amnesty International is on it:
Amnesty International @amnesty – 15:50 UTC · Nov 19, 2019
At least 106 protesters in 21 cities have been killed in #Iran, according to reports we have received. Verified video footage, eyewitness testimony & information gathered from activists outside Iran reveal a harrowing pattern of unlawful killings by Iranian security forces.
".. eyewitness testimony .. gathered from activists outside Iran …"

The Iranian government decided to increase Iran's super low gasoline prices. The new price will only apply to the amount of gas that exceeds a subsidized 60 liter per family per month. The additionally money will be distributed to the poor.
The move makes economic sense. It had previously been recommended by the IMF.
The usual suspects have used the announcement to launch protests and riots in several Iranian cities. Some banks were set on fire and security personal were attacked. The CIA and the MEK cult are certainly trying to push for additional disturbances. The Iranian government cut internet access to prevent that.
As long as I can remember such protests and riots have happened in Iran every other year or so. They usually die down within a week. I am confident that the same will happen this time.
But that of course does not stop the "regime changers" and their claquers from raising the usual nonsense. So we get "eyewitness testimony" from "activists" who are not in Iran on events that allegedly happen within Iran.
It is interesting that they don't even try anymore to make sense.
A Rocket Scientist here on the board suggested this…
https://en.wikipedia.org/wiki/Geostationary_orbit
Let us look into Rocket Scientist’s helpful pointer…
A geostationary orbit, also referred to as a geosynchronous equatorial orbit (GEO), is a circular geosynchronous orbit 35,786 kilometres (22,236 miles) above Earth’s equator…
Like William pointed out already…GEO sats ARE NOT USED FOR EARTH IMAGING…
For the simple reason that the optics required would be FAR in excess of the Hubble telescope…
Anyway…it seems you presume to have more technical knowledge of aerospace physics than I do, which is why you have chosen to dispute my point…
Of course you could have looked up Earth Observation Satellite BEFORE proceeding to demonstrate your lack of a preschool diploma…
Most Earth observation satellites carry instruments that should be operated at a relatively low altitude…Earth observation satellites are all operated at altitudes of about 800 km.
Do you need me to explain the physics behind why a sat flying at 800 km altitude needs to go 18,000 mph…?
It’s not actually hard to understand…ever seen the ‘hammer throw’ event in the olympics…where the athlete spins a heavy metal ball on the end of a cable around and around before releasing it…?
Before he releases it, the spinning ball is obviously exerting a very large CENTRIFUGAL FORCE…the cable is keeping it from flying off, by exerting the exact same force in the opposite direction [centripetal]…therefore the two forces are in equilibrium, as per Newton’s Third Law of Motion, which tells us that for every action there is an equal and opposite reaction…
It is the same with a satellite…in order to stay aloft and keep spinning around the earth, its centrifugal force must exactly equal the pull of earth’s gravity…
Since centrifugal force is a factor of the object’s rotational speed, a spacecraft flying in low earth orbit must have a speed of about 8 km/s [about 18,000 mph] in order to develop the CENTRIFUGAL FORCE THAT WILL EXACTLY BALANCE THE PULL OF EARTH’S GRAVITY…
That way, the two forces are in EXACT EQUILIBRIUM…just like that spinning ball in the hammer throw…
Do you have any other insights about orbital mechanics that you would like to educate me on…?
Now let’s get back to the earth imaging sats…in order to cover the entire earth surface, they are placed in a Polar Orbit…
That way the sat is moving around the earth in the vertical plane, while the earth spins below it in the horizontal plane…
That means that a sat will be only momentarily above any particular point on the globe…since the earth is spinning under it, and the sat itself is flying very fast in a perpendicular plane of rotation…
In practical terms, it means that any given spot on earth will only pass under the sat maybe once in a few days…
Now let’s get back to your Einstein-level contribution of suggesting a geostationary orbit nearly 40,000 km from the earth as a means to take pictures of the earth below…[SMFH]
Here we refer to what’s called the Dawes Limit…which is…
a formula to express the maximum resolving power of a microscope or telescope.
This resolving power is measured in angular resolution
The formula is given as…theta = lambda / diameter
Where theta is the angular resolution in radians, lambda is the wavelength of light, and diameter is the size of the optical lens or mirror…
The wavelength of light in the visible spectrum is about 5 x 10^-7 meters…which is about 5 ten-millionths of a meter…
The Hubble telescope has a mirror of 2.4 m, so the angular resolution would be 0.000,000,5 divided by 2.4 = ~0.000,000,2 radians…which, in degrees, equals 0.000,01 degrees…
Now to find the resolution at a particular distance…for example of a GEO satellite which is 35,786 km [~36 million meters]…
To get the linear resolution we multiply the distance times the angular resolution in radians and get…a linear resolution of about 7.5 meters…
Compare that to sat imagery which is now well under 1 meter resolution…for instance 41 cm [0.41 m] for the IKONOS sat…
That is nearly 20 times greater resolution than the Hubble would give from a geostationary orbit…
Would you like to teach us anything else today…or will that be it for now…?

@ bevin 19 (at least until the deck gets shuffled again)
I went looking for the comment you referred to @Zedd 11, because I just thought it dumbfounding when I read it yesterday. Apparently b has expunged it, so thanks for quoting it and refuting it so well. No, it doesn’t square with anything, does it? And if it were true that Rouhani was an Israeli mole, why would Israel be the first to try to exploit that fact? Too clever by half?
I often read (but don’t participate in) the forums on Truthdig. The Israeli messengers are all over editorials there about this, reinforcing the accusations that Iran and it’s leaders are the foulest demons from the very depths of hell, unequaled in their malevolence in all of history. They continue to do it I suppose because there are still so many that continue to bite, chew, and swallow it. Some poster there (TD) feigning obsequiousness helpfulness said, to the effect – “please, Iran, don’t you think it’s time to sit down and talk with the US?” And do what – get handed the terms of their surrender, their enslavement?
I have a plea myself: Hey Europe! – feel around in there and see if you can locate a backbone! Same goes for you China. I know it’s risky and you are risk averse, but your time has come. I don’t think it is a stretch to point out the symbiotic economic dependence of US/China: If one goes down, both go down, and that reality should work as well as any nuclear restraint treaty.
But, I’m ranting. I’ve tried mightily in these last several decades to learn and understand as much as I could about Iran, the ME in general, of Islam and the tribal diversity of that region. I’m no expert, but better informed than many who don’t have the time or inclination to pursue that information. And I’m still in the lagging pack of “also rans” on a site such as this. However, let me posit this: The Islamic Republic of Iran learned, rather harshly, the contours of world power during the Iran/Iraq War, and little has changed since then. Few friends would come to their aid, as today. They are understandably suspicious and cautious. Overtures from China or any other competent power, for them, are fraught with both existential and pragmatic dangers. Persia/Iran has a very long history with Russia/USSR/Russia (Glazunov’s tone poem, Stenka Rozin memorializes some of that (better known for the Song of the Volga Boatmen, what the Wicked Witch of the West’s castle guard were chanting.))
OK, because you didn’t ask: It is an obscure piece, seldom performed, and the story goes like this, as best I remember from the liner notes of the piece of vinyl I have. A beautiful Persian Princess was aboard a royal barge on a journey up the Volga River to be a gift and a bride for a Russian Czar. The Volga Boatmen, river pirates led by Stenka Rozin, intercepted and overpowered the Persian entourage, and Stenka Rozin began to woo the beautiful princess. The Czar learned of this treachery and sent his forces to rescue the princess. A large battle between the Czar’s forces and the Volga Boatmen ensued and both Stenka Rozin and the princess were killed – drowned in the Volga River. Like much Russian musical composition it evokes tragedy, and is laced with historical implications. That one was simple; try following Pushkin’s Russlan and Ludmilla and Mikkel Glinka’s balletic adaptation of same.
So, sue me. Just trying to be the guy in the bar when a fight is about to break out that says “Hey, have you heard the one about the leprechaun and the elf…”
