GPS

most high-school physics students are aware of this effect.

That's giving way to much credit.

Flying rodents compensate for the frequency shift detection.

I'm probably in the minority, but I have been trying to make sense of any of sceptimatic's postings.

He seems to always deny the known scientific facts of just about any subject and make up some weird something or another of his own.
 

I can assure you that you're definitely not alone in with this LOL.

People such as sceptimatic often lack any grounding in basic science, possibly due to a lack of education (and I don't say that to denigrate anyone).  They rely mostly on personal perceptions, instincts, and logic.  And often all three are erroneous.

Like some people perceive the earth as being flat, or think they should be walking up or downhill if the earth's a globe, or that gravity doesn't exist because they can't feel it.  As do flat earthers.

Anyway..... the easiest way for people with limited scientific knowledge to defend their shortcomings is to mount ad hominem attacks on their opponents—which is precisely what sceptimatic does in every second posting. It's also noticeable that he doesn't have any opposing scientific theories of his own—he thinks it's sufficient to simply describe everybody else's theories as "bullshit".

At any rate, I'm guessing none of us will be able to get anything of merit through to him as he's so negatively biassed that it's really a waste of time.

I'm telling you it cannot work with no medium.

based on what logic.

Accept that and move along ...

not really how it works, you keep saying open your mind and question, well who wouldn't question that assertion and if you have anything other than imagination backing it up?

You don't believe in a vacuum so you can't possibly know what would occur in one and that's even making the assumption that the whole of space is a complete vacuum, which it's not.

Have we established why they are called satellite TV dishes and why none point north in the northern hemisphere?

no, we haven't even established why the ones on the southern coast point out over the ocean.

Show me some proofs about this Doppler shift in GPS signals and we can go from there.

Too easy.
 

Notice the compression of the sound's wavelength on the right of the front of the car.  To each of the listeners, the cars sound has a different pitch—caused by the Doppler Effect.

Ok, let me clarify what I mean.

Show me how this doppler shift works for GPS signals. I'll give you a massive clue. I want to know how it works in , like, how does it travel from thousands of miles in space through the atmosphere to our cars or whatever.

Start off with how it propagates through your space.
Am I making myself clear, here?

You explain to me how space is not a complete vacuum. Just tell me what exactly is in space in that darkness that stops it from being a vacuum?
So basically I need to know what elements are in space that can act as a medium for signals and such.

If you dare come back with stupid stuff like dark matter or light particles then do not dare sit there and tell me that I don't know what I'm talking about, so make it good.

Dishes will point to wherever the transmitters are situated. It's as simple as that. The transmitters are all earth based, not space based.

Please give us the locations of some specifically for 'satellite' TV.  The installers must know where they are to set up new dishes.  In the UK they all point south, even on the south coast, so can't be in the UK.

When you see a TV news truck with a dish, where is that transmitting to?  The man in the truck says it's to a satellite.

Are you incapable of doing any of your own research? For such A Supposed free thinker you like you all your info to be spoon fed to you don't you.

GPS is old technology, repackaged as satellite based.

First of all, GPS and GSM (cell tower) location do not use triangulation.  They use multilaterantion.
Secondly, who ever claimed that multilateration was anything new?

Are you incapable of doing any of your own research? For such a supposed free thinker you like you all your info to be spoon fed to you don't you.

Our friend sceptimatic does indeed.  That way he can avoid actually answering any questions put to him.  He simply responds to any questions by asking another one of his inquisitor.  All too easy.  And very fucking obvious.

I'm afraid that you're the last person on this forum that should be asking for people to "play nice".  You repeatedly denigrate people, insult their intelligence, dismiss their opinions out of hand, and refuse to offer any legitimate input of your own apart from snide comments about science and scientists.  You consistently refuse to answer people's legitimate questions, and instead return nothing more than scornful schoolyard taunts.

You're the classic bully: safe and secure, hurling insults from behind the safety of your keyboard.  But face-to-face I'm guessing you'd be the first to turn tail and run given any sort of opposition.
 

 

It's quite funny actually;  you think you're a big man, but everyone here thinks your a mental midget.

The 'apparent view' is where you think it's pointing, the 'actual view' is where it is actually pointing. Pretty simple stuff once you understand it.

Yes, it looks exactly like this. So now they don't have to be angled because they can simply catch the signals now, even though just a slight movement would render them useless.
It's about time you realised that they are simply receivers from transmitters. Go and have a look around from the way your dish points, I'm sure you will find one.

I see you completely missed the point there. The dish is still very directional, even the slightest movement will result in lost or degraded signal, it just doesn't point where you think it does. Here, let me show you again:



The 'apparent view' is where you think it's pointing (almost horizontal), but the 'actual view' is where the dish actually receives it's signals from. If you had learned anything about parabolas, you would know how and why this works, and why one of these dishes (with a little modification) can be used to heat a frying pan:

" class="bbc_link" target="_blank" rel="noopener noreferrer">

Note where the shadow of the wood is falling, as this shows that the dish's 'apparent view' line is not pointing at the sun.

Even if scepti doesn't get this, I hope the rest of you get something out of it.

lots of stuff, clouds of gas, random atoms, background radiation...

again, your logic behind the need for a medium is...?

If you dare come back with stupid stuff like dark matter or light particles then do not dare sit there and tell me that I don't know what I'm talking about, so make it good.

wouldn't dream of it, that stuff may or may not be there, it's theoretical. It's also not necessary, there's all sorts of stuff out there that exists beyond the spectrum we are able to see directly with our eyes. Space is merely considered a near vacuum when compared to earth.

Let me ask you this, whats in the space between air particles? and if there's NO space between air particles then how can air pressure vary?

we're dealing with dishes all across the south coast that point over the ocean.

You think I'm lying and that the dishes actually point north but nobody noticed?

You really want me to find time to ride down to the coast in the middle of winter to photograph a dish on a house that you'll have to take my word for it is facing the ocean?

Or would you accept a google streetview image that you could pan to see both the ocean and the building?

Because I'm prepared to find you the second.

Let me ask you this, whats in the space between air particles? and if there's NO space between air particles then how can air pressure vary?

As far as I can gather, scepti seems to believe that all molecules are like sponges: there is no space between them, but they are compressible, allowing for the variation in pressure. Thing is though, if air molecules were like little sponges, how would we move? I mean, what would be easier to walk through, a room jammed full of sponges? or a room partially filled with ping-pong balls that are bouncing around at a moderate rate?

So basically I need to know what elements are in space that can act as a medium for signals and such.

This type of electro magnetic radiation only has detectible medium based wave like properties when interacting with a medium, refracting, reflecting or diffracting. Travelling between molecules/atoms, it has particle properties. (Photons is the quantum term here). Yeah scepti radio waves is the same thing as light waves with longer wave lengths than infra red light.

This is called Wave particle duality. Read it up.

Yes; it's an actual photographic image taken from one of the US space shuttles.

I don't understand precisely the science behind the image, but I do understand what it's representing—which is tiny particles floating in the vacuum of space.

And no;  I'm not a scientist by any definition of the word!  I'm just an average guy interested in what makes our planet tick.
