A Modern Terrella!

[Solar]

Take a look at page 42 of the linked .pdf:

Collisionless Plasma in Space Physics

To be mentioned:
Terella Birkeland: (1899)
Planeterrella: Lilensten (2006)
Historically important and beautiful pedagogical tool (but no new physics to investigate):

He said “no new physics to investigate”. Then why, as Michael Gmirkin has observed in the thread “In Slumber, Sun Reveals Effects on Earth's Climate!”, hasn’t potential connections between the Earth’s “jet stream migrations”, and maybe even its Plasma Bands, i.e. equatorial as well as polar aurora dynamics, been investigated in relation to Birkeland’s findings?

I then looked up “Planeterrella” and came across this by Lillisten et al:
The Planeterrella, a pedagogic experiment in planetology and plasma physics

We present here a plasma physics experiment which makes it possible to simulate, in a naive yet useful way, the formation of polar lights. It involves shooting electrons at a magnetized sphere placed in a vacuum chamber. This experiment, inspired by K. Birkeland’s Terrella, built at the turn of 19th century, allows the visualization of very many geophysical and astrophysical situations. Although delicate, it is feasible at undergraduate level.

At any rate, the research lead to what appears to be the only modern terrella in existence by way of a personal pages for Laboratoire de Planetologie Grenoble

Enjoy!

This needs to be a primary teaching tool. Viv'la France!

Great find! Where's my vacuum pump?

[junglelord]

wonderful pictures. The "naive" comment, I don't buy.

Was Birkeland's Terrella the first microwave oven?

Cheers!

Solar,
Here is a photo of a 1966 Nasa experiment to which you linked on another thread:

A Nasa simulation of Van Allen Belts with a terella

http://www.nasa.gov/multimedia/imagegal ... e_419.html


Now let's see we can duplicate auroras, van allen belts, saturn type rings, and other observed astronomical effects by shooting an electric current to a metal sphere in a vacuum chamber...hmmm
nah, can't possibly mean anything

makes it possible to simulate, in a naive yet useful way, the formation of polar lights.

Translation: we would not want our students to conclude that there are electric currents in space that actually do something!

Could they be even more obvious of there denial? Maybe to there minds its naive!

So this begs a question, why are they "the naive" avoiding the electric currents in space? Is it to simple preserve their established dogma ( their grants ?). Or are they really that ignorant? Or they think that they are in fact with out a doubt unfalsifiable right?

BTW, useful in what way? I wonder!

Thank you for posting a link to that photo. Like yourself and JL I found the "naive" comment simply bizarre. That, and the "no new physics to investigate" comment from the "Collisionless Plasma" link. Makes one wonder why we bother to continue to send up probes if there is "no new physics to investigate". But, I think that it is part of the disconnect.

[webolife]

This thread, and its links, may just be the best thread I've seen on the EU for the last 4 years!
Thanks Solar, Nick, et.al. Maybe they thought it wsa naive because it was written in French!
Que c'est stupide!

[junglelord]

When they have a experiment that recreates the actual large scale, and call it niave, someone is brainwashed.


When you tell people that the universe is electric, they think your nuts.


Then they stick a picture of a super bright plasmoid in front of you and tell you its a black hole....and being brain washed at one time, I believed them, dispite what my eyes saw.....quite the slight of hand/eye/mind/.


You tell me who is nuts!


I will tell you who is niave and who is brainwashed.....


I know it's not kosher, but face it, the EU is top secret thoughts and science.
The public deception is part of a very contrived coverup that has been going down since the 1900's!
By 1935 it was already beyond public mindset for the reasons I just said.....its top secret.
A very methodical and consistent control of public information, and control of the public "mindset" has been ongoing ever since. That is the only "rational" explation.

I watched all of the MIT electricity magnatism lectures.
You CANNOT POSSIBLY have such a course and NEVER mention the name of TESLA.
You could not possiblly run a Tesla Egg and go on and on about how THIS CHANGED the WORLD....and never call it for what it was or who invented it!

You could not possibly interject at the end of Lecture 1and say with a straight face to a group of students, that contarary to "common sense", the entire lecture just preached to you, exists only on earth!

And by design, the outer space around us is a flip/flop controlled by gravity....and that electicity is not in space!

Or could you?

Hi junglelord:

junglelord states:
"....and being brain washed at one time, I believed them, dispite what my eyes saw.....quite the slight of hand/eye/mind/."

I appreciate the above comment and am curious, what sequence of events, ideas, or evidence made you conclude "modern" astronomy was on the wrong track?

I'll just say for myself, I was never under their thumb or in their "community", so I never had cause to closely examine their beliefs before now. Of course, I was aware of what they claimed, but that's not the same thing.

You on the other hand as suggested by the above comment were much "closer" to the "community".

I hate to say this, but judging by their comments to anybody who questions, expresses scepticism, or outright rejects their beliefs, their reaction is much like a "cult".

I'll offer a comment or a series of comments, indeed, debates where I got the better of them, IMHO , over at say, Universe Today, and long after I've been retired from the thread, they continue making ad hominem attacks and over-the-top strawman arguments belittling Plasma Cosmology (sometimes, I've not even made a comment on a particular post and my screen moniker will be kicked around).

What drives such vitriol?

(Supposedly, Universe Today recently imposed a "be nice" policy with offender's comments to be deleted, but it seems not to be enforced against those that are obvious "defenders of the faith".)

(It's as bad as any political blog I've read.)

And rarely, will they offer any meaningful critique of even the more outlandish claims, such as, "mini black holes everywhere" Mostly, it's slavish following of the "party line" and "boy what a fantastic idea" -- the "fantastic" irony goes right over their heads. Also, anybody who shows the least bit of incomprehension (but doesn't appear to question the basic tenents), gets a swift dose of "explanation" or "don't you worry, we'll have this figured out in the near future".

Yes, I do have some notions about their motivations, but your perspective as an ex-cult member (if that's not too strong a term to use) would provide valuble additional insight.

I hope these questions don't bother you, if they do, I aploogize, but I am curious about your transition out of the "cult" and your insights into their attitude as expressed by their comments.

Their attitude doesn't have a lot to do with the Scientific Method at least as I've been brought to understand it

"Cult Member Speaks Out"

Well I am a self motivated amature astronomer. My love for the "black hole" comes from my other hobby as a drummer.

Since the two coincided with a song by Rush called Cygnus X-1 back in 1977, I have been a believer of that notion until I heard the EU story on Coast to Coast in late Nov of 06.

I could never swallow the dark matter and dark energy crap.

Having dated a Jehovah Witness for two years, I have seen first hand how a cult operates.
She was not a witness at the time, but the rest of her family was, and now she is too.
Wonderful people, but very deluded.

Then I came to see that I was the one who was brainwashed....into the cult of cosmology!


Everything about the EU makes sense.
Everyone out there fights tooth and nail to retain the facade of all the fakeouts going down right now.
The brainwashing is deep. The incultrination is effecient. If you see a UFO, YOUR CRAZY.
If you say the universe is electric, YOUR CRAZY.

And yes I have seen the mud slinging that goes on when you even mention this on a forum.

Sad thing is, I am a very rare personality type, INFJ,
http://www.humanmetrics.com/cgi-win/JTypes2.asp
only 1.5% of the population actually is a INJF.
I wish there were more of people like me....but sadly there are not.

I got an INTJ..only 1.0%...I feel so alone!!!

@ junglelord:

I appreciate your response.

To get back on topic: The terrella experiment is just as valuble, today, as it was during Birkeland's time, which is to say, very valuable and insightful.

When the terrella is able to reproduce so many observed astrological phenomena (not just one or two), it seems ludicrous for them to blithely dismiss it as "naive".

But that demonstrates their general hostility to electromagnetism in space and their lack of historical awareness.

But truth is the electromagnetism perspective is being confirmed in the solar system by in situ observation & measurement at an accelerating rate.

But apparently, the right hand is so hostile to what the left hand has done, that it refuses to fully inform itself of the left hand's activities

[webolife]

I'm hoping you meant "astronomical", not "astrological"?

[Anaconda]

Oops, yes, thanks for correcting me

Although...sometimes...I think "modern" astronomy is closer to the latter than the former
