Today has been a good day; meaning I've worked continuously all day, and feeling like I've been effective. Still, when I look at what I've actually accomplished, it doesn't really look like much: six different ways of plotting one of the resonances I'm studying - to try to see if there is some kind of pattern in it. 
Pattern hunting.
Good thing is that I've might have found something, but I'm not sure before I've discussed it with Sunniva tomorrow.
I also managed to write a couple of sentences on my article...
BTW: I finished my poster for PhDDay, which is next Friday, yesterday, so that's good 🙂 I wish I'd had more time to work on it, but I'm quite happy with the result (guess three times if it's pink 😉 ), and now it's just to wait for the poster session and see how it goes... If you're at the University at 11 (AM) next Friday, you're welcome to stop by and check out our posters of our research.

I am so sorry I've been away for a week now, but Jon (my supervisor from Paris) was here, and we've been working more or less non stop. Don't get me wrong; I love these kinds of visits, and of course there's also been time for socialising after a long day at the office - what Jon calls work hard, play hard.
If we'd skipped the socialising bit I guess I would've had time for updating here, but the part where we're actually also friends, and not just colleagues is so important - I don't even really see that as an option. Therefore I'll repeat: I'm sorry I've been away, but I'm not really sorry for the choices I've made; we've made great progress and had a lot of fun at the same time.
play hard - Sunniva and Sunniva at Herregårdskroen <3
But to the title; yes, it's all getting real now... 
We went through the article that's almost finished, and even though we didn't finish it completely (which was sort ofa a goal), I feel really close now - and sure that I'll make this last part by myself 🙂
We worked on the gamma rays, and we did start the next article. 
And me and Jon went through the entire outline for my thesis, and he said something I took as a big compliment: I'm not at all worried about you writing this thing, you'll do a great job, I'm sure of it. Jon really is Mr. WorriedGuy, so when he says something like this, it really means a lot 🙂
I feel like from now on it may come more weeks like this one, where I actually won't have time for updating the blog. Wish it wasn't so, but then again it feels really great to take these leaps forward, towards the finishing line. It's still a lot to do, but tomorrow I hope to finish the last big "hole" in my article, and if Sunniva approves, we'll send it off to all the co-authors (that won't happen tomorrow, sine I know Sunniva'll have quite a lot of comments, and then I'll have to fix all those, but then maybe it's time...;) ).
Another thing that's getting real is Alexandra becoming a big girl; today she had her preschool visit at her school; in just two and a half months she'll be a real school girl. That's such a big leap, and somehow it feels surreal and fantastic and almost sad (not really sad, but "strange sad" that she's not a little girl anymore) - all at one time <3

Hver morgen, når klokken er seks, våkner vi at at radioen skrur seg på, og det er selvsagt P2 som gjelder hjemme hos oss - jeg digger P2 (#voksenpoeng)! 
Jeg er nesten alltid superfornøyd og imponert over kvaliteten på det som denne radiokanalen serverer mellom klokken 6 og 9, men i dag ble jeg småskuffet og litt irritert; det var nemlig en merkelig sak som handlet om at forskere publiserer "for lite" på norsk*. 
For å utdype denne Twitter-meldingen litt, og forklare hvorfor det ikke er et valg å publisere  for eksempel fysikk på norsk:
I akademia så er det publisering som gjelder: Publish or perish. Forskningen vår skal (selvsagt) være på et topp internasjonalt nivå! Vi må publisere, og vi må få artiklene våre fagfellevurdert. Forskningen vi driver med på instituttet vårt er også svært spisset, og vi er noen få i Norge som driver med det vi gjør**. Så en norsk journal der jeg feks kan publisere kjernefysikk fins ikke, og den hverken bør eller kan lages (den ville automatisk ha blitt på et MYE lavere nivå enn enhver internasjonalt anerkjent tidsskrift, og størsteparten av det eventuelle publikummet for denne journalen ville måtte jobbe med å lage/drifte denne).
Videre kunne ikke fagfellevurdering fungere fordi det ikke er nok fagfeller i Norge som kunne vurdert en artikkel skrevet på norsk. Hvis det er noen som faktisk har kompetanse til å forstå det som står i artikkelen så er de antageligvis medforfattere på den aktuelle artikkelen, hvis ikke vil det være noen som ikke kan fagfeltet, eller de kan fagfeltet, men ikke norsk... 
Til sist så ville vi ikke kunne samarbeide med de vi samarbeider med - internasjonaliseringen forsvinner (de kan ikke være med oss, og vi kan ikke være med dem); vi gjør mange eksperimenter på andre kjernefysiklabber rundt omkring i verden - feks i USA, Sør-Afrika, Frankrike, og Japan. Disse eksperimentene resulteter i artikler, som vi samarbeider om å skrive. Det blir fryktelig vanskelig å skrive disse sammen med forskere som ikke snakker norsk - hvis vi er tre norske og 15 fra diverse land rundt omkring i verden (de andre forskerne må jo tross alt kunne forstå teksten de er medforfattere på, ellers ville det vi drev med vært mildt sagt grovt uetisk), og av samme grunn så kunne ikke vi være med på artikler skrevet på fransk, tysk, eller japansk (vi kunne vært med på den engelske/amerikanske, da, men det er kanskje ikke helt rettferdig hvis vi skal få masse ut av samarbeid med dem, men de skal ikke få noe ut av samarbied med oss - eller kanskje vi bare skal forvente at de lærer seg norsk?)
Publish or perish gjelder overalt i akademia, så det må kunne være ganske sannsynlig at samarbeid resulterer i artikler, ellers forsvinner mye av insentivene for å bruke tid på dette.
Vi bør vel kanskje ikke skrote internasjonalt samarbeid, fagfellevurdering og nivå, bare for å få artikler på norsk...
At dette i det hele tatt er en diskusjon (slik den ble lagt frem på radioen i dag tidlig) er bare rart og feil. Vi publiserer SELVSAGT ikke på norsk, for det er hverken mulig eller ønskelig. Forskningen er internasjonal, og da må den også deles med internasjonale forskere på et språk som er internasjonalt forståelig. (Vi kan godt være litt triste over at norsk ikke er et internasjonalt språk, men sånn er det nå en gang, da...)
For meg så viste denne diskusjonen noe som kunne minne om en manglende innsikt i mye av forskningen som foregår på univeristetene - hvis man tror at veldig mange av oss bare kunne ha publisert på norsk istedetfor på engelsk, så er du i mine øyne omtrent ikke meningsberettiget.
Grunnen til at forskningen vi gjør er utilgjengelig for folk generelt er ærlig talt ikke at den er publisert på engelsk. Vitenskapelige artikler er ikke formidling.  Jeg tør faktisk påstå at forstår du faget, så forstår du engelsken. 
Her er noen eksempler på artikler jeg er medforfatter på: 
Experimentally constrained (p, γ)89Y and (n, γ)89Y reaction rates relevant to the p-process nucleosynthesis (12 forfattere som ikke forstår norsk - som ikke kunne ha vært med, og som i prinsippet gjør at artikkelen ikke kunne ha eksistert)

Study of the 238U(d,p) surrogate reaction via the simultaneous measurement ofgamma-decay and fission probabilities (5 norske forfattere - vi kunne ikke ha vært med på denne hvis den ble skrevet på hovedforfatteren sitt morsmål, men heldigvis publiserer de på engelsk også i Frankrike)
Experimental level densities of atomic nuclei (16 forfattere som ikke forstår norsk - som ikke kunne ha bidratt til det endelige resultatet). Denne er jo til og med nesten populær i sin fremstilling. Abstractet lyder:

It is almost 80 years since Hans Bethe described the level density as a non-interacting gas of protons and neutrons. In all these years, experimental data were interpreted within this picture of a fermionic gas. However, the renewed interest of measuring level density using various techniques calls for a revision of this description. In particular, the wealth of nuclear level densities measured with the Oslo method favors the constant-temperature level density over the Fermi-gas picture. From the basis of experimental data, we demonstrate that nuclei exhibit a constant-temperature level density behavior for all mass regions and at least up to the neutron threshold.

La meg være litt grei, og gjøre en rask oversettelse av dette abstractet:

Det er nesten 80 år siden Hans Bethe beskrev nivåtettheten som en ikke-vekselvirkende gass av protoner og nøytroner. Siden da har alle eksperimentelle data blitt tolket i dette bildet av en fermion-gass. Dog har den fornyede interessen for å måle nivåtettheten ved å bruke forskjellige teknikker gjort at denne beskrivelsen må revurderes. Spesielt så favoriserer det vellet av nivåtettheter målt med Oslometoden konstant temperatur-nivåtettheten fremfor fermigass-bildet. Med bakgrunn i eksperimentelle data de
monstrerer vi her at kjerner viser en konstant temperatur-nivåtetthetsoppførsel i alle masseregioner, og i alle fall opp til nøytron-bindingsenergien.

Jeg brenner for formidling, og jeg skulle gjerne hørt en diskusjon som handlet om hvordan forskningen skal gjøres tilgjengelig for andre enn forskerne, men det problemet med formidling er ikke at vi publiserer på engelsk.
Hadde det vært en diskusjon om formidling; at det formidles for lite på norsk, og nå må vi gjøre noe for å belønne formidling på norsk, så er jeg også helt for diskusjonen. Men det var altså snakk om publisering, og da blir det hele mer eller mindre tragikomisk.
--------------------------------------------------
*Det er klart, dersom spørsmålet er om forskning som handler om spesifikke norske forhold, og hovedsakelig er av interesse for nordmenn, så er det jo ganske merkelig å publisere på engelsk (vi er alle, eller i alle fall de aller fleste av oss, selvsagt bedre i vårt eget morsmål, enn i engelsk, og dermed vil antageligvis også det vi skriver få en litt høyere språklig kvalitet på eget morsmål), men slik det ble lagt frem så handlet det generelt om at forskere publiserer på engelsk.
**For å illustrere: Anders driver også med PhD i fysikk, og selv om vi da har ekstremt mye av den samme bakgrunnen, og snakker veldig mye sammen og forklarer for hverandre, så er det jeg kan si om hans forsknng ca dette: han programmerer masse også holder han på med noe molekyler, blant annet silikat. Å lese en artikkel i hans fagfelt vil være ekstremt krevende for meg - om ikke umulig...

I've been working my ass off analysing data since Monday morning - wanting to be as prepared as I can for Jon's visit later this week. It's tedious work: studying a plot, finding time limits, change your code, run the program, check the results, write everything down and put it into different folders - and start all over again. Repeat until dead tired.
But speaking of working my ass off, even though I work hard, I still want to feel fresh - without spending too much time or effort on it...entering the three working your ass off hairdos:

1. messy bun
2. messy braid no 1
3. messy braid no 2

The point with these three hair styles is to save time; all of them can stay for a week or so, and at the same time look fresh. You can wake up, and you're hair's already done, meaning there's one less thing to fix in the morning! They are all of the "messy" kind - meaning they are supposed to look a little like you just came out of bed, and not too "perfect" 😉

The hair should not be washed when you make these - I typically wait one or two days after the last time I washed my hair. In the picture below I hadn't washed my hair for 3 days; and also you don't need to comb your hair (I only do that like once a week, or something - before I wash it) - the best result of all these three hair dos comes without combing 🙂

This thing from Define is a real life saver! It's actually a mixture of dry shampoo and hairspray at the same time, so it's just perfect for making your hair look fresh and voluminous. Also it makes the hair so much easier to work with (newly washed hair is the worst; so little volume, and so straight, and so slippery).
Ok, let's start 🙂

The messy bun and the messy braid number 1 and 2 start with the same messy pony tail (steps 1-3):

first you need a thin rubber-band (1), then gather the hair for a pony tail at the crown of the head (I use both hands for it - 2), and wrap the rubber-band around the whole of the hair until it feels secure, not too tight (3). The combination of a pony tail that is quite loose, and placed high up on the head, makes it possible (not even uncomfortable) to sleep with 🙂
the messy bun is made like this: take the pony tail and twist it loosely (4), continue twisting it until it's wrapped around the rubber-band, and then stick the end back under the rubber-band (5) - it looks like this at first (6). To finish it I mostly just pull the bun, but a couple of bobby pins helps get it "down", and at the right place (7)
I often wear my hair like this when I'm giving a talk. Unless I'm super nervous and afraid I won't be taken seriously, or something, the messy bun is a good choice (of course, in combination with the right outfit ). Below you can see what it looks like when I just made it, and what it looks like after a week - I normally prefer it after a couple of days.
messy bun <3
The messy braid no 1 has the same starting point as the messy bun - the messy pony tail.
You need two rubber-bands for this one. Divide the pony tails into three parts, pull them forwards, and start braiding quite loosely (1). Secure the braid with a rubber-band (2). It first looks a little simple and dull, but then there's magic: hold the braid with one hand on each side of the braid (my other hand is busy holding the camera at this picture :/) and pull gently (3). Continue pulling at different places along the braid until you're happy with the size/volume (4), and then, finally place the braid at the right side of your head  - the back side (5)
The last hairdo is the messy braid no 2. Some extra hair spray is often a good idea on this one.
First, gather all the hair loosely on one side (1). Sometimes I use a comb to tease the hair a little bit by the roots, so it won't be as flat as it was here... Then divide the hair into three equally sized parts, and start braiding (2) - remember: not tight! Then simply braid as far down as you want - I prefer to keep a decent portion of hair not braided - secure the braid with a rubber-band, and pull the braid the same way as the messy braid number 1 (3)
Messy braid number 2 is very soft and feminine <3
(I don't have thick hair at all, but the messier it is the thicker it looks :D)
All of these three hair dos should be so loose that you can sleep comfortably with them. When you wake up you just apply some dry shampoo to the roots, and you're ready for working your ass off!

even though it's messy doesn't mean it can't be serious 😉

I write about this work I'm doing all the time, but I have never written anything about what really constitutes a PhD, so I thought this week you'll get 10 FACTS about how to get a PhD:

  1. After you get a master's degree, you can continue with a PhD
  2. The actual PhD work is 3 years, but many of us also have 25% teaching so that we have the job for 4 years in total (the teaching is normally done during the time you also work on the degree)
  3. To be admitted to the PhD program at the University of Oslo, you have to have quite good grades; B as an average on the courses in your master's degree, and at least B on your master thesis
  4. Most of the PhD degree is research, but you also have to take one semester (in total) with courses (one of the courses is a mandatory ethics course - which sounds like a good idea, but when I took the course, I thought it wasn't a particularly good course...:/ )
  5. My courses were the ethics course, one called "Communicating Scientific Research", a statistics course (STK9900), and a nuclear structure course ("advanced nuclear structure and reactions")
  6. The main part of the PhD is research; you have to do stuff that is new, and the results must be of such a quality that it's published in serious, peer reviewed joournals (if your work isn't worthy publishing, well, then that's too bad for you - no PhD!)
  7. The actual "thesis" is a collection of the articles you write (often it's something like three), and an "introduction" where you sort of sow everything together (which can be challenging when you feel like your articles have almost nothing in common), and write in detail about the methods you've used, and experimental setup, and theory and stuff (for example, I write about nuclear power in general, nuclear reactions that are interesting and important for nuclear reactors, simulations of nuclear fuel, and the Oslo Cyclotron Laboratory, and of course there is some kind of conclusion after the articles 🙂 )
  8. When everything is finished (your research, your article writing, your thesis writing, and your funding), the entire thing will be sent to a committee (experts in the field, of course 😉 ) that will read everything carefully and decide whether the thesis is worthy of defending, or not. (If they decide it's not at all worthy, you don't get a chance to make it better, and all your work is worthless for the degree - if still you want to get a PhD then, you have to start ALL.OVER.AGAIN.)
  9. After the committee says the thesis is ok, you'll get the date for the thesis defence, and two weeks before this, you get the title of you trial lecture that you have to prepare for the thesis defence. This could be almost anything (is my impression), but it's normally related to your research
  10. The last part is the day of the thesis defence: it starts with the trial lecture, and if this is approved, then you get to actually defend your thesis. The defence happens later the same day; first you give a short presentation of the work, and the two opponents will ask all kinds of questions about it and discuss with you. After they've finished, people in the audience can ask questions. All of this is public. At the end of the day, after the committee (hopefully) approves of your work, you have to have a dinner with the opponents and your supervisor, and maybe your friends and family <3
I guess you can say I've finished points 1-5, and more or less number 6, and now I'm mostly working on the rest of point number 6, and 7.
not sure which one is most correct for me, but I'm leaning towards the first...:P
 
This week my supervisor from Paris, Jon, is coming, and my goals for the work with him is to make a draft of an article about prompt fission gamma rays, discuss my thesis draft, finish my article about uranium-234 and send it off to all the co-authors. Really (!) hope we/I manage all this...!

Hi everybody <3
I know it's Friday, I know I didn't write anything yesterday, and I know it's time for Friday Facts... Unfortunately, I'm pretty busy today with data analysis, in addition to the fact that Anders' office mate had his PhD thesis defense today - and after that I've been busy getting Alexandra from kindergarten to my parents in Skedsom (who are taking care of her until tomorrow). Now I'm on my way to the thesis defense dinner, and suddenly this day is over :/
So, I'm sorry there won't be any facts today, but I'll fix it by the end of the weekend! For now, here's a picture of what gamma radiation from fission looks like, and a selfie from last week when it was all sunny and nice  🙂


Last week, when I was out with girls, Anita told me you have to wear something Norwegian for your thesis defence...what about byTiMo, it's just perfect for you! I hadn't really heard about it before, but she showed me their Instagram account, and I could see why she thought I needed something (or more) from them 😉
On Saturday, when Anders and I were out, being a couple, drinking wine, and shopping for the 17th of May, we stumbled across by TiMO on Byporten (I had no idea they had a shop there), and of course I had to go in. Anita was so right, and I ended up with two dresses (Anders got me one of them, since I had trouble deciding, and he thought I looked good in both <3). The one on the pictures here was perfect for 17th of May, and luckily we had the most fantastic weather yesterday, and the other one is a dress that may actually be suitable for my thesis defence (the day will come...). I won't show you the other one yet, since if I'll use for my thesis defence, then I sort of want it to be a little bit of a surprise.

Here are some snapshots from yesterday - needless to say, I think; I love my new, beautiful, pink, flowery dress <3

Today I've had a good chat with Sunniva (supervisor), about the layout I've made so far for my PhD thesis, and about some plans I have about writing another article - which will be more of a "popular" type of article. She was all for it, and she was also very enthusiastic about the work I've done with my thesis (which is not at all much, but at least I've started)!

A normal misconception about nuclear physics is that it's all about nuclear power and/or atomic bombs, and that that's it. This is far from the truth, and therefore I think 10 facts about nuclear physics is a good idea today 🙂
  1. nuclear physics is  all about the atomic nucleus - discovered by accident by Ernest Rutherford a century ago, when he was bombarding a thin gold foil with alpha particles
  2. there's so much we don't know about the heart of the atom - the nucleus; and that's why we are a lot of people around the world still spending all of our lives to study it, and try to understand the nucleus and the nuclear force that holds it all together (how does it really work, and why, and how big can a nucleus actually get?)
  3. all atoms have a nucleus - nuclear physics is as much about the non-radioactive nuclei (stable gold, stable oxygen, stable iron), as the radioactive ones (thorium, uranium, plutonium) 
  4. the "applied part" of my phd thesis is about nuclear power, which is of course also one part of nuclear physics - how to produce energy from big nuclei that splits in two (you get heat and you can boil water and you get steam and then you can generate electricity)
  5. I don't want to lie; atomic bombs is also something that some people (not in Norway) study - knowledge about nuclear physics can be used in such a destructive way. As can most knowledge if I think of it...
  6. knowledge about nuclear physics tells us about the creation of the elements - what happens in the sun and similar stars; how do they get their energy, and what happens there? In stars like our sun, elements all the way up to iron are produced
  7. no elements that are heavier than iron can be produced in stars/the sun, but we know they exist  so they must have been created somehow (we know gold exist, we know thorium exist, we know there is lead - to give some examples), but not where they came from. Creation of these heavy elements is actually one of the great mysteries, and we think they are made in explosions or collisions in space. We use nuclear physics to try to figure out how and where all these elements are created.
  8. one of the really nice applications of nuclear physics is radiation therapy. Atomic radiation may cause cancer, but it may also cure cancer <3
  9. if you've ever had a CT scan, you've experienced applied nuclear physics. Think about it: it's kind of awesome that we can actually look inside the body, and get really great images of the inside, without even cutting it open...!
  10. PET, which is short for positron electron tomography is another imaging technique in the nuclear medicine, where you actually detect gamma radiation from an electron that meets its anti particle, the positron (awesome, seriously!). And from this you can create beautiful three dimensional images of for example a tumour inside the body

Nuclear physics is seriously awesome <3<3<3
