3. We generally play with fire before getting burned and learning lessons from it

Thats all well and good exiting the cave and progressing to more advanced living, but when calculating that a miniature black hole could get let loose by CERN, but the chance is so small we just need to roll the dice anyway, that's wreckless bud.

And please dont give me the blah's about how it would just evaporate away by emitting Hawking radiation, I dont believe it. It will find the center of mass of our planet and start growing no matter how minuscule it was to begin with.

5. Your example shows why we need to put forth a lot more effort towards pushing humankind out...

...into space (ie living on space stations, living on the Moon, living on Mars, etc). That way the scientists who want to experiment with such powerful and potentially destructive forces could do so safely away from where the vast majority of everyone else is living. Their F'ups wouldn't wipe out humankind as easily as they could do today.

16. Yes.

At least on a personal level.

I have no idea what it's like to be in prison. Hope I never find out.

I have no idea what a homosexual encounter is like. Hope I never find out.

I have no idea what a meth addict's lifestyle is like. Hope I never find out.

And so on ...

GPS receivers use magnetism to navigate because satellites are not accurate.

I am in New Orleans and a GPS knows where I am within a few feet, and I use the GPS to travel to Chicago where I know where I am within a few feet, but I'm not sure I took the correct heading.

Got it.

17. Why don't you explain it to us in your own words?

not just a link. I'm well aware magnetic variation and deviation need to be constantly updated on navigation charts for people that navigate with a compass (a dying breed) and it needs to be updated for cell phone compass apps.

18. Lol. How did you put it?

Do some research?

You've had a few days now and still haven't looked into it.


Oh due to your edit... I see you did finally look it up. And now pretend you knew all along.

It needs to be updated for marine navigation and the military relies on it all the time especially for undersea navigation.
Air traffic control, GPS.. all rely on accurate declination numbers.

You are getting close..
Almost there..

24. I said the WWM is programmed into cell phones.

In the other thread.

You came into this one claiming I said GPS uses magnetism.
Neither I or the article said that.
You then mistakenly mixed up satellite GPS and cell GPS, now you are trying to back pedal.

3. Fake News

GPS Navigation has NOTHING to do with magnetism



SatansSon666 (6,040 posts)
4. It says cell phone GPS.

It says it's based off the world magnetic model.


For example, WMM is pre-installed in Android and iOS devices to correct for the magnetic declination.

https://en.m.wikipedia.org/wiki/World_Magnetic_Model


6. Compass app?

Who said anything about a compass app?

It says cell phone GPS.

I even linked the information about the model they had to adjust with an excerpt for you that says it is programmed into cell phones.
That is what needed to be adjusted.





SatansSon666 (6,040 posts)
10. The WMM is programmed into cell phones.

It takes into account for variations in declination. It's usually updated every 5 years, but due to the recent movement they had to fix it faster to.maintain accuracy in...
Wait for it. .

CELL GPS.


SatansSon666 (6,040 posts)
12. I didn't quote fake news.

Look up magnetic declination.
Look up the world magnetic model.
Then look up why the WMM is programmed into cell phones.
Then look up why the WMM had to be updated ahead of schedule.

If you are using a cell based GPS to navigate, wouldn't you want it pointing as close to magnetic north as possible?
Well, without the update, you'd be going off course quite a bit.
It's real simple.
For most people.



SatansSon666 (6,040 posts)
14. It's for cell gps.

Nothing to do with satellite gps.

"True north and magnetic north are 2 different things." Yes.. that's what declination is.
If it's not updated you won't be going true north when navigating..

Maybe you don't care if your navigation equipment is off. People that rely on it do care.
Not talking about Google maps here and driving through a city GPS.

That's why they updated it earlier than they were supposed to because it would throw everything off.
If you are using cell GPS to navigate in the dark, i think you'd want it to be as accurate as possible. The correction had to be done for this reason.
There is nothing fake about it.



You never, EVER admit you are wrong
Now you know cell phone GPS uses satellite too. That's what GPS is.
Some cell phones use a "poor man's GPS" by using cell towers. They can do that because cell towers have latitude and longitude co-ordinates. They use triangulation off the towers just like real GPS uses triangulation off of satellites,

Neither one use magnatism
In order to navigate with magnatism you must factor in more than deviation. You must know the variation also, something you don't seem to be aware of.

Nice to see you finally looking the stuff up.
Even if you still have to put words in my mouth, you learned something.
