The ■■■■’s were terrible people but history seems to of forgotten the horrors that Stalin subjected his own people to.

The simultaneous Soviet invasion of Poland is often left out of the official narrative as well but ask anyone Polish about it and I bet they won’t have forgotten they typically seem to hate the Russians far more than the Germans.

It’s been well documented that the Russians were more brutal than the Germans.

Can’t let that one go unchallenged

and you make a fair point, if we take the extermination camps alone, yes then Jewish were the higher number, take into work camps were people were worked to death including able bodied Jews, with little or no food, shot when they were unable to work any more then in the whole “Holocaust” of seeing some folks as sub human then the Jews were in a minority far more Russians and Poles were shot and gassed when they were no longer worthwhile, viable to work, than Jews. But the whole focus on the atriocities commited focuses on just on sector the Jews, - The Poles, Gypsies the Russians the disabled, the mentally ill, the political opponents don’t get a mention

But you made the specific claim that “More disabled, mentally ill ,homosexual, non politicaly conformists were sent to the camps and killed or experimented on than Jewish people” and that simply is not the case at all. Those groups only accounted for a small minority of those incarcerated and killed in the camps (about 12% of the total). About 40% were Jews, 20% Soviet PoWs and 20% ethnic Poles, Ukranians and Belarussians.

Fair point again, I was using examples, but I should have put an “etc” in there, done a more extensive list on simply said more Non-Jews. The basic premise of my post remains, the atrocities have gone down in history as Jews being the victims and the rest have been forgotten.

Thats because some people dare to ask questions
While other just swallow [zb].

Some conspiracy theories hold water. The twin towers being the work of the CIA for example makes a bit of sense if you listen to the right peoples take on it. (The right people being experts, not lunatics on forums who claim to be experts in plane dynamics, building structure and engineering and insult anyone who doesnt believe them by calling them stupid)
The problem with people like you is you cant have a reasoned debate to put your points across. You simply tell everyone your reasons and then proceed to call anyone who questions you stupid, gullible, thick or whatever and that just makes you come across as a keyboard basher who sits in a tinfoil hat in a basement with posters of aliens on the wall.
You remind me a bit of woody harrelson in the film 2012, only he wasnt as barking mad as you

Not sure you really asked any questions mate, you pretty much made a statement based on ignorance, and that’s why you’ve been shot to pieces… How the hell this moved on to WW2 though! :open_mouth:

But anyway. Yes the Russians were extremely brutal, and history probably doesn’t make much of this as they were reacting to the extermination squads that followed in behind the front line when the Germans initially invaded…

Blimey, even the forum manager has gone wildly off topic!

im on a plane at least once a month…I have never ever put it on flight mode…it just stays on,so why does it lose a signal once your well up in the air?? :slight_smile:

Marine and aviation sat navs work better than your car or truck sat nav because they have to be constructed to more stringent regulations before they are passed for use, they can also one be a hell of a lot more expensive.

Seen a few programs about planes , the repo one the buffalo air one and wild pilots and all seem to use some form of what looks like car sat navs

Roymondo:
The other big numbers were for Soviet POWs (estimates vary - 2 or 3 million) and Poles (maybe 2 million).

Keep in mind, the Polish government during the Cold War exaggerated the numbers of Polish victims, especially at Auschwitz. However, I’ve heard estimates of millions of Russians, Belorussians etc killed in “anti-partisan” warfare and not all of these would have been POWs.

How come these “satellites” never need maintenance,how come they never get struck by micro meteors,how come their batteries never fail(and before you give me some crap about solar panels if they are in geosynchronous orbit they must be in the dark half the time)How do they put them in orbit,these things dont have engines and the “shuttle” only goes up to 400 miles,How do they maintain a none decaying orbit without engines not just over weeks but 20 years.

Think of something in orbit as always falling but never getting any closer to the earth. Because as it travels forward, gravity pulls it towards earth at the same rate as the curvature of the earth (the earth isnt flat really) moves away from it. Arthur C Clarke derived the geostationary, or “Clarke Orbit” way back in the sixties IIRC.

Because there is little resistance at the height these things operate at, Newton’s laws of motion are clearly apparent. Most notably, an object in motion will remain in motion until a force acts upon it. Therefore, with careful calculation, an object placed in the right place at the right speed by the delivery vehicle will stay where it’s put. (See gravity above)

There are some people cleverer than you or I out there, I find it worth listening to them sometimes.

A yes dear Arthur Never did quite “explain” how he became such an expert on “telecommunication” satellites did he?Maybe he studied between writing crap science fiction novels.And there is me thinking that “gravity” was a force or does gravity ignore these miraculous “satellites”.See force is measured in Newtons and what is Mr Newtons most famous discovery? Thats it “GRAVITY” the “force” that pulls things down out the sky(except satellites of course they fly with little angel wings)

I love this.

Are you saying gravity should pull satellite s from space into earth?

If so sir you are a top class world standard wind up merchant and I applaud you.

The moon( a satalite it is classed as) is in a falling orbit. Continually falling to earth but due to magnetic and other forces it does not hit earth. but if you are saying gravity has had enough and is going to pull it into us please let me know as I want to run up some more debt first.

As for the accuracy of speed question. There are many variables which would have to be factored in to determine most accurate, like tyre pressure and such like.

But a big variable in my mind is the time difference between gps satellite and gps receiver. If einstein theory of relativity is true the time at the satellite will be different than that at the receiver due to the difference in gravity. This is resolved by an equation at receiver level. How much accuracy will be involved in the equation for a £50 sat nav which is not designed to accurately measure speed (it will say it in the instructions). Then you add in that the earth’s rotation varies and the equation needs fixed values. Mind blown.

Need to stop now have fallen over. Thinking typing and breathing, multi tasking not my strong point.

Einstein’s theories don’t say time is affected by gravity, but it is affected by relative velocity. Unless something is moving at a speed which is a significant fraction of the speed of light, the effect is negligible.

The US actually monitors 24/7 and adjusts the time on each satellite to ensure the accuracy of GPS positioning, all the SatNav device has to do is compare the difference in time of signals from different satellites and calculate position accordingly.

Vehicle came in for 2 year tacho check and speed was 85 kph,sticker fitted all done.
Next day vehicle brought back because it was "really " doing 92 kph.

Some numpty would rather believe some bloody sat nav over the tacho calibration.
He says to me its “satellite” and much more “accurate”
I ask him has he ever seen a satellite?Has he ever tried to use a “sat nav” on a ferry in the middle of the North sea or on an aircraft?Has he ever noticed that “satellite” dishes always point in the same direction as ordinary “yagi” aerials?

“sat nav” uses old technology from the 1940s eg radio mast triangulation but with a “map” programme built into a phone or receiver.Thats why they do not work at sea or in aircraft.
Ships and aircraft use short wave signals for navigation but microwaves from cell phone masts only works on line of sight transmission.His parting shot was “well if I get done for speeding I will blame you”
If GPS satellites existed why do we need upward of 30,000 cell phone masts just to cover the UK.
Another bloody con job

Will have to admit I for once agree with bking on this…Maybe not have put it the way he has …and I know for a fact he has never agreed with anything I have said …But sat navs are not a recognised system for calibrating tachos…So no matter what a sat nav says ,it s the approved calibrated tacho rollers along with the rest of the approved calibrated tools that dictate the K W L factor …You are allowed up to 6 kph in a speed for speed check…So at the end of a calibration you run the vehicle at 50kph on the rollers and when you hit 50 kph the calibration tool and the tacho should be within 6 kph macx of each other …
If a customer came in and said his sat nav was saying something different to the tacho ,then if he wants to pay I would recalibrate it and if it still reads different to his sat nav then tough .DVSA do not recognise sat navs as a calibration tool …

I now await abuse from bking as I have never had a nice word from him :smiley: :smiley: :smiley: …go on bking you know you can be nice

When I took both my HGV tests, the examiner (two different ones for class 2 and 1) had a GPS speedometer because he couldn’t easily see the fitted one. I presume it relies on the same technology as a sat-nav.

So if my truck is doing 56, and the one passing me is doing 56, is he travelling back in time or am I going forward? What about when the truck I’m passing is doing 56 and I’m doing 56…

yep probably still the same technology ,but it still isn’t dvsa approved for the calibration of tachos…Obviously something the test centre is using where you are ,though they do not use them up here …It doesn’t matter if they are more accurate or not ,it what the calibrated rollers say …And that is where we are ,until someone change the system

Captain Caveman has given a nice concise explanation of how an orbit is achieved without resorting to vague assertions about “magnetic and other forces”. And yes gravity is continually pulling satellites towards the earth, but they (hopefully) dont reach the ground as the earth curves away before they land. Satellites, of the GPS type have a life of about 10 years. GPS satellites are about 22000km up in medium earth orbit. Geosynchronous satellites are about 36000km up in high earth orbit. They have solar arrays to charge batteries for their electronics needs and rockets for the maneuvering needed to maintain orbit, or put them into a parking orbit when they are decommissioned. From low earth orbit they are put into an elliptical transfer orbit. When at the "highest" point of this orbit they are put into a stable high orbit. They are subject to damage from natural and man made objects and may be protected by shields. Also, 2 satellites had a collision in 2009. Dunno who filled out the insurance forms for that one. Arthur C Clarke was, before becoming a sci fi author, awarded a first class degree in maths and physics by Kings College London. This was after his RAF service in WW2 when he was involved in RADAR and other research and development.

Also involved with radar was Watson Watt from Brechin.He wasnt pleased when the police caught him speeding with an early model radar speed trap.

Looks to have been an interesting character.

Some of the early radar work was done near here (Daventry, Northants) with a borrowed RAF bomber as the “target” aircraft and Watson-Watt and his colleagues monitoring the reflected radio transmissions from the BBC transmitter site at Borough Hill. There is a monument to this along the old B4525 towards Litchborough, just off the A5 near what used to be White Park garage (now a commercial vehicle dealership).
