It Took More Than 100 Years to Bring Winter Sunlight to the Town Of It took more than 100 years to bring winter sunlight ChasINg the suByN Kara Eliason to the town of Rjukan, Norway. But thanks to high-tech mirrors, the results have been dazzling. jukan is a town nestled in the Vestfjord Valley southwest of R Oslo. The surrounding mountain peaks offer a majestic view, but they also have a dark side. They block out sunlight from September to March, meaning residents spend half the year in the mountains’ shadow. That changed on Oct. 30, 2013. On that day, three giant mirrors on the side of Gaustatoppen mountain sat ready to reflect rays of sunlight into Rjukan. Residents anxiously gathered in the market square to witness it for the first time. “We were excited, but there were a lot of clouds that day. So we had to wait a few minutes before we could turn on the mirrors,” says Karin Rø, who works for the Visit Rjukan tourist s office.

  • Som Nær Sagt Ingen Anden» Sam Eyde (1866 –1940)
    TROND AASLAND «… som nær sagt ingen anden» Sam Eyde (1866 –1940) et er gått 1 50 år siden Sam Eyde ble født i Arendal, men vi starter i DFrankrike for 80 år siden, da han rundet de 70. I forkant av dagen gikk Eyde i filmstudio og leste inn et ungdomsdikt om en ung mann med hjemlengsel og kjærlighet til fedrelandet – en som «ønsker å komme til - bake en gang…» Det var som om han for andre gang befant seg på feil sted, denne gangen i et påtvunget eksil. Hans hilsen hjem til Norge ble også formidlet gjen - nom radioen, men den ble ikke tatt godt imot av alle. Strengt tatt flyttet han aldri tilbake, men i vår tid synes det å være bred enighet om at han er kommet hjem. Han står ganske stødig som vår viktigste gründer og industribygger, i alle fall i de første formende tiårene av forrige århundre. Han står slik både på grunn av og på tross av Sam Eyde. Kunne andre ha tatt en tilsvarende rolle? Vi skal være forsiktige med å legge det meste på noen individer. Historisk utvikling er alltid et samspill mellom tidens breie elver og manøvrene til farkostene ute på vannet. Hadde ikke Eyde kommet, kunne andre sett og grepet mulighetene og fått til noe rundt store norske fosser. Trolig ville vi fått se mer av utenlandske kapitalister og mindre av samarbeid og overføring av kunnskap og teknologi. Sammensetningen av industri ville ha vært annerledes. Tidsforløpet likeså. Hydros produksjon er det vanskelig å tenke seg uten det avgjør - 9 ende initiativet til Eyde og møtet med professor Birkeland.

Early on Birkeland was interested in magnetism and already as a schoolboy he had bought his own magnet with his own money. He used the magnet for many surprising experiments and practical jokes - often irritating his teachers Birkeland’s Early Career Birkeland became a certificate teacher at the University of Kristiania at only 23 years old and graduated with top grades. In 1896 Birkeland was elected into the Norwegian Academy of Sciences at only 28 years old. Two years later he became a professor in Physics - quite unusual at that young age at that time (was called «the boy professor»). Photograph of Kristian Birkeland on Karl Johans Gate, (Oslo) in 1895 taken by student Carl Størmer, using a concealed camera. (source: UiO) Birkeland - Electromagnetic Waves Birkeland did laboratory experiments on electromagnetic waves in 1890 and first publication came in 1892 with some ground breaking results. In 1893 he focused on the energy transported by these waves. In 1895 Birkeland published his most important theoretical paper. He provided the first general solution of Maxwell’s equations for homogeneous isotropic media.

  • Sam Eydes Kvinner
    RJUKAN-NOTODDEN INDUSTRIARV Sam Eyde og kvinnene Anne Haugen Wagn Kan ekteskapene og kvinnene i Sam Eydes liv bidra til å belyse industrigrunnleggerens personlighet? Og fork- lare hans karriere og nederlag? Uansett forteller disse sidene av Sam Eydes liv historien om borgerskapets mannssamfunn. Der kvinnene var underordnet mannen. Og der de fikk utfolde seg, enten som hore eller ma- donna. Ole Kristian Grimnes, som har skrevet biografien om Sam Eyde i 2001, skriver at Eyde var så altoppslukende opptatt av sitt arbeid at det gjorde han immun mot begivenheter og forandringer i privatlivet. Det er ikke stort å hente hos ektemannen for et studium av industrimannen, skriver Grimnes videre. Men, det burde være mulig å utdype forståelsen av Eyde som industrigründer og leder, ved å se nærmere på han som ektemann. Første ekteskapet 17.august 1895 giftet Sam Eyde seg med Ulla Mørner i Skeppholmskyrkan i Stockholm. Sam bar løytnants uni- form, hun var i hvit brudekjole med halvlangt slep, en liten utringning foran ved halsen og lange ermer. Etter noen hvetebrødsdager ved Saltsjøbaden, reiste de til Lubeck. Anna Ulrika ( Ulla ) ble født 13.juni 1873, som yngste datter av den svenske adelsmannen Carl Robert Stellan Mörner af Morlanda. Ved dåpen bad han noen i Eydefamilien om å være fadder, fordi kontakten her var allere- de etablert. Ullas far døde mindre enn 2 år seinere, men kontakten med Eyde-familien fortsatte. Mor til Ulla, Sally, ble alene med 6 mindreårige barn og måtte selge herregården. Men underbruket Marieberg ble beholdt, og Ulla vokste opp der. Sommeren 1891, da Ulla var 18 år, besøkte hun og moren eydene i Arendal.

  • Sam Eyde – Norsk Hydros Grunnlegger
    RJUKAN-NOTODDEN INDUSTRIARV Sam Eyde – Norsk Hydros grunnlegger Sam Eyde kom første gang til Notodden som 18-åring. Da er han ingeniørstudent og har skrevet seg inn i gjesteboka på Hotell Furuheim på Notodden. Og han kommer tilbake til Telemark. Fire år seinere, sommeren 1888, skriver han sitt navnetrekk sammen med tyske venner i besøksboka på Gaustatoppen. Eyde nøyer seg ikke med en signatur. Han tegner også inn Rjukanfossen og - til overmål – tegner han en bro med svevebane tvers over dalen! Det viktigste med turen til Rjukan var likevel at han også studerte Rjukanfossen. Eyde merket seg at det var voldsomme krefter i den fossen, og at den kunne brukes til noe…. Sam Eyde (1866-1940) ble født og vokste opp i Arendal, der hans far drev med shipping. Som barn likte han bedre å leike ved havna og klatre i riggene på seilskipene enn å fordype seg i skolearbeidet. Da han var 13 år, ble han tatt ut av skolen og mønstret på skoleskipet ”Nornen”. Han omtaler det selv som en slags dannelsesreise. En måte å bi voksen på. Den unge Sam fikk se verden og fikk erfaring og opplæring i det virkelige liv. Eyde skriver i sin selvbiografi at han på denne turen lærte seg tre viktige ting: Disiplin og vennskap med offiserene om bord - og at det var en verden utenfor Arendal. Sam fullførte gymnaset (videregående), avtjente verneplikten og ble kadett. Han søkte seg til det tekniske univer- sitetet i Charlottenburg, utenfor Berlin. Her ville han utdanne seg til ingeniør. Sam gjør det bra på studiene, han vinner en pris ved universitetet for sitt arbeid.

  • Kristian Birkeland: the Great Norwegian Scientist That Nobody Knows
    KRISTIAN BIRKELAND: THE GREAT NORWEGIAN SCIENTIST THAT NOBODY KNOWS Birkelandforelesningen 15. Juni 2017 av professor David Southwood, Imperial College, London Introduction Ask a foreigner for the name of a famous Norwegian. Rapidly one discovers that the late nineteenth century produced a flowering of Norwegian cultural talent as, as likely as not, the nominee will come from that time. These were, of course, years of an increasing sense of Norwegian identity, the years lead - ing up to Norway’s independence from Sweden in 1905. The list of Norwe - gians easily identified by a foreigner would surely include Henrik Ibsen, Edvard Munch, Edvard Grieg, Fridtjof Nansen, Roald Amundsen. However, one man would be missing. Despite being featured on the tail planes of Nor - wegian airliners and familiar to Norwegians after featuring for 20 years on the 200 NoK banknote, Kristian Birkeland will not leap to foreigners’ minds. Even if you asked for a scientist, one might get Abel, Lie or Bjerknes before Birkeland. Why is that so? Here I shall attempt to explain this conundrum. A detailed biography has been given by Egeland and Burke (2005). In ad - dition, an English journalist (Jago, 2001), has written a biography that is al - most a novelisation of his life. That this could be done, marks how multifaceted this man was. Birkeland was obsessed with the Northern Lights. The elegant picture in Figure 1 illustrates this, and Jago brings out this clearly. Egeland and Burke, both scientists, make clear how close he came to understanding their origin. I’ll try not to repeat too much of what is told in the two books.
