Today I learned about the mysterius word: Terella – A model of the Earth designed to illustrate the magnetic field. From the net I found this about the phenomeno:
Electromagnetic waves led to radio and television, and to a huge electronic industry. But they are also generated in space – by unstable electron beams in the magnetosphere, as well as at the Sun and in the far-away universe, telling us about energetic particles in distant space, or else teasing us with unresolved mysteries.
In Norway, aspecially on a clear winter night, you can easely see this in the Northern Lights, described as: “Of all naturally occuring heavenly phenomena, few come close to a night with a magnificent northern lights display. Flickering curtains of dancing light against the dark skies, northern lights is certainly one of the most spectacular of nature’s phenomena.” See a wonderful picture of this in the links in this article below!
And of course there was a Norwegian who started the surch of this phenomena: “Birkeland published the first realistic theory of the northern lights, the main point being that electrically charged particles ejected from the sun are captured by Earth’s magnetic field and directed towards the polar atmosphere. To prove his theory, Birkeland performed his famous “Terella” experiment, where he artificially created the aurora – and by doing so he amazed the entire scientific community.” Copied from the linked site of this article.

Welcome to Norway to experience this magic yourself!
I had a meeting today with Kjell Rusti, CEO of Steria Norway. Entering their reception desk I noticed that the view out of the window at the 23rd floor was breath taking. Since I have a mobile phone with camera, I could not resist taking a picture from the top of Oslo – capital of Norway. In the picture you can see the fjord ending right down town of the city and the ferry boat regularly cruising from Denmark and Germany. Right now the harbour is under construction as the new Opera House is beginning to form its magnificent shape as an architectural new monument. If you like to learn more about this coming Opera House in The City of Oslo, click here! On the net at www.fodors.com miniguides, I found this description of Oslo which I find excellent: “World-class Oslo, a town of 500,000, has become good at survival and rebirth throughout its nearly 1,000-year history. In 1348, plague wiped out half the population, and it has burned down too many times to count. Nearly destroyed entirely by a fire in 1624, it was redesigned and renamed Christiania by Denmark’s royal builder, King Christian IV. After that it slowly gained prominence as the largest and most economically significant city in Norway.” A Yahoo user from Germany says: “This is the best city I ever been to. Fantastic surroundings, very clean and friendly beautiful people. The perfect place to take your kids. They will be safe and not bored. If you want nightlife go another place(even though there is good places) This is a city very suited for families.Quite expensive but it’s worth evey penny. Make sure too go to the resistant Museum, Bygdoy and just stroll around in the city and enjoy the friendly atmosphere.” A norwegian couldn’t have said it a better way! You are welcome to visit any time :-)
I’m not new to this, but wanted to start all over again. Trying, experimenting and exploring this new way of communicate with the world. If I don’t exite you right away, bear with me. I will go on trying and give you some of my life in this Cyber Space way.
So stay tuned, there will be more and more and more!
