So it turned out I was looking at the wrong output from my Talys nuclear reactions simulations , of what happens when a uranium-233 nucleus is being bombarded with neutrons with all kinds of energies. (Talys is a program for simulating lots of types of nuclear reactions; it's free, online, and everyone can check it out here, if they want to 🙂 ). When you run a simulation (or 60, like I have) you get a folder with lots of different files, and silly me was looking at the wrong file... "Of course": the file I needed to plot wasn't the "totalxs.tot", but the "rp092234.tot". If I'd read the manual more closely this would have been clear, but it's more than 500 pages. Still on my to do list to read it, though.

This a typical research story (at least in my world) - and, oh, how I hate it!

Yes, it does feel sort of good when you realise why things aren't working, but it's not like I've solved a great problem, I just happened to be an idiot, looking at the wrong output file (and, of course, it's nice to not be an idiot, but the solving this is'n taking me big leaps forward - I'm just not an idiot right now).
I guess I just have to repeat to myself: Never give up.

no matter how you feel, get up, dress up, show up, and never give up!

I.

LOVE.

SPRING!

I had to take two (long) coffee breaks on the stairs of the physics building today - just to feel the sun <3
Luckily I'm giving a talk in an hour, so I actually HAD to do something today (prepare for the talk, of course). Otherwise, I'm not sure if I'd been able to do anything at all today 😛
I've been thinking about that, whether spring and sunny weather is best for productivity, or cold, dark weather: If it's sunny and beautiful, like today, I just want to be outside (and I spent more time out in the sun than I probably should have today), but if it's cold and dark and wet, I don't want to leave bed. Tough choice, productivity wise, but I think the nice spring weather we're experiencing today makes me so happy that even though I spend less time in the office, I'm more effective when I'm actually working, so that spring is best for productivity. 
What do you think?

Happy Monday peeps, hope you all had a great weekend <3
I have to start this day with a blogpost I started on Friday, but unfortunately didn't have time to finish...:/ Friday was March 11 - marking the five year anniversary of the Fukushima accident. 
This accident is actually more or less the reason why I started blogging, and to really care about outreach of science. I saw how scared people were, even here in Norway, and my "medicine" to that are facts and knowledge. (This is also the way I tried to "comfort" my mother when she had radiation treatment; telling her everything I knew about radiation and doses and biological effects and so on... Don't know if it really helped for her, but it "helped" for me, since it was the only thing I could do.)

So I wanted to give you ten facts about Fukushima on Friday, but instead you'll get it now:
  1. On the 11th of March, 2011, Japan was struck by a "triple catastrophe": massive earthquake (9 on the Richter scale) that lead to an enormous tsunami, that both lead to the accident at the Fukushima nuclear power plant (NPP)
  2. The Fukushima NPP reacted exactly as it was supposed to during an earthquake: the control-rods went into the reactor and shut it all down (stopped all the fission reactions in the fuel) - it was actually what you could call a "flawless automatic shutdown"
  3. When a reactor is shut down, with all the control- and scram-rods inside it, it can't start again - so there is no (and it wasn't) danger for a chain reaction out of control (which is what happened in Chernobyl - an accident extremely different from this accident), but you still have all the fuel, which is radioactive, inside the reactor and this needs to be cooled. Even though the chain reaction has stopped, and heat caused by radioactivity isn't a big factor compared the hat that actually comes from fission (around 10% of the total), it's still more than enough that it will be extremely hot if it isn't continuously cooled properly.
  4. To cool something you need a medium that can carry away the heat, like water, and you need that medium/water to flow. After the earthquake and the shutdown of the reactor, this wasn't a problem, since there were diesel generators that came online and operated the coolant pumps - so that water was flowing and cooling and doing it's job.
  5. So part one of the triple catastrophe was the earthquake (and it killed a lot of people), but then the tsunami came (and it killed a lot of people), as part number two, and it immediately caused part three of the accident; wiping out the diesel generators. After this there were only some backup batteries, but they didn't last for long, and then there were no more cooling pumps, and in my opinion this is when the real problem at Fukushima started. 
  6. No pumps = no flow of cooling medium/water = no cooling anymore = fuel rods heat. In nuclear engineering language this is called a  loss-of-flow accident (short: LOFA), a little bit similar to the accident at Three Mile Island in 1979.
  7. Since the fuel rods are radioactive they produce heat, and since there are no cooling, they become extremely hot; and if the water then comes in contact with the zirconium cladding of the fuel (which it did), free hydrogen is produced from the water (there is a lot of hydrogen in water). 
  8. Hydrogen is an explosive gas, and when it came out of the reactor tank it exploded. Such an explosion is definitely not a good sign, but I believe it looks even worse for some than it actually was... This was NOT a nuclear explosion. What blew up was NOT the reactor tank, but the building around it. 
  9. Since it became so hot inside the reactor, the fuel melted (which is what we call a melt-down), and then radioactive materials were released from the inside of the fuel to the water (normally, there are no radioactive materials in the cooling water that flows around the fuel rods).
  10. No one died of radiation from Fukushima.

I realise it's impossible to only give 10 facts about this accident, and I will continue very soon (Friday perhaps....? 😉 ). 
Now it's time to prepare for a talk I'm giving tomorrow, for a small bunch of science journalists, then I have to look at my actual PhD thesis - which is on the plan this week...

Hva er god undervisning? Hvor er de beste foreleserne nå for tiden? Hvordan bedømmer man egentlig kvalitet i undervisningen? Er den klassiske forelesningens tid virkelig over? Hve lærer studentene å tenke?

Jeg er utrolig stolt over å ha blitt spurt om å være med når Morgenbladet skal kåre Norges beste foreleser! Sammen med Helene Uri, Erling Sandmo, Therese Eia Lerøen og Victor Norman, skal jeg være med å finne vinneren. 
Vi har i denne sammenhengen alle forsøkt å svare veldig kort på to spørsmål: 1) Hva er god undervisning?, og 2) Hvorfror er god undervisning viktig? Slik svarer jeg: 

1. Et viktig nøkkelord er «trygg». Den som underviser, må være trygg på det faglige innholdet og trygg på seg selv i rollen som underviser. Hvis underviseren i tillegg er engasjert og åpen, vil studenten føle seg trygg og motivert – to viktige faktorer for læring.
2. God undervisning kan kurere en students dårlige selvtillit, slik at vedkommende kan få realisert potensialet sitt. Motsatt, med dårlig undervisning, tror jeg man kan være uheldig å miste nettopp dem som kanskje har et stort potensial, men som trenger en ekstra «push» for å få det ut. Disse studentene kan godt ende opp med å bli de beste, men med dårlig undervisning kan de kanskje like gjerne falle av.

Alle kan nominere den de mener er akademias beste underviser. På nettsiden kan du også lese andres nominasjoner (allerede noen timer etter at dette ble publisert hos Morgenbladet har det kommet mange nominasjoner - GØY!), stemme frem kandidater og dele nominasjonene videre. Frist for å nominere er 15. april, og juryens liste med ti navn presenteres i august.
Les om kåringen (og juryen) HER, eller gå direkte til nominasjonssidene HER 🙂

(Kan forresten ikke fordra det bildet de valgte av meg. Bildet er hentet fra reportasjen om Kvinnene som forsvant, og der ble det jo tatt så mange andre fine bilder - kunne de ikke heller valgt et annet, feks dette som de brukte på forsiden da de kjørte denne saken? 😛 #skikkeligluksusproblem)

Remember my last post about #workingyourassoff-dinner? My super-easy super-fast Thai-reipe? If not, you can check it out HERE.
Well, life here is quite busy, as always these days (yesterday started at quarter past four in the morning, since I was going to Stavanger to give two talks, and then back to Oslo to go to a celebration of the international women's day - I fell asleep before my head hit the pillow when i finally got to bed last night), so there is no less need for quick and tasty recipes - but the same Thai all the time is a little bit boring... So a couple of days ago I made another #workingyourassoff-dinner, but this time more Mexican inspired.

Before I share the recipe with you, let me just refresh the rules for a real #workingyourassoff-recipe:


The recipe for working your ass off simple chili con carne:

You need:

  • green beens (frozen ones - I love these, and use them in all my #wokringyourassoff-dishes)
  • leek (prechopped, from the freezer)
  • mushroom - I use champingnon (prechopped, from the freezer)
  • meat - this time I happened to have fresh, minced meat, but it's of course possible to use frozen
  • Tabasco sauce - the one with chipotle is just perfection <3 (I also have a lot of different chili sauces, like normal Tabasco, habanero Tabasco, plus some others; and I use a little bit of everything to get the perfect taste, but I can really recommend the chipotle!)
  • extra virgin olive oil
  • chopped, canned tomatoes
  • cinnamon
  • butter
  • salt and pepper
  • (if you happen to have some old wine, it's perfect to put it in the pot)
You can also add peppers (all colours), tomatoes that are not canned, eggplant, squash (the peppers and the eggplants taste awesome if you chop them, put them in a ovenproof dish, pour some olive oil on top, and grill them in the oven - then put them in the pot. This of course takes more time, so then it's not longer a real #workingyourassoff dinner anymore ;)). I'm personally not that fond of canned beans, but if you like it, it's of course perfect to add. They're cheap, and since they're canned, you can store them forever before you find out that you want to make a chili con carne.
these ziploc bags from IKEA are perfect <3

the perfect Tabasco for a Mexican inspired pot of chili <3<3<3
a glass of wine is always a good idea (maybe unless you're driving, or you're pregnant, or you're 16 😉 )

 Do:

Put some flavourless oil, like rapeseed oil, in a pot. When it's real hot, add the meat and a table spoon of butter (mmm, butter <3). Stir.
When the meat is fried, add the leeks and the mushrooms. Make sure it doesn't get burned by stirring 😉

Then add the canned tomatoes. Th
is time I used two cans, since I wanted everything to be more "soupy" and less dry. Add a little cinnamon - maybe just half a teaspoon. Add the Tabasco, and/or other chili sauces. I like it spicy, so I use quite a lot - the secret is just to taste, add more, taste, add more, or not, until it's perfect for your taste 🙂 Let everything boil for a while.
Add extra virgin olive oil (I use a lot - olive oil <3) and green beans. It's all ready when the green beens are warm. It only takes a couple of minutes.
Serve it with rice or bread, or just eat it as it it - which is what I do; with salt, pepper, and some sour cream on top.
This is of course not my "very best perfect fantastic gourmet"-recipe for Mexican food, but the very easiest and fastest way (I can think of) to do it. 
It's quick, it's simple, and it's quite tasty - what you need when you're busy working your ass off <3 

I'm not sure why he looked like this - but, hey, he's a guy - you can't understand why they do everything they do 😛 (He was actually very happy about the food <3 )

Good morning good people ❤️

I'm currently at Gardermoen, waiting at the gate for my flight to Stavanger, which is today's travel goal. I'm going there to give two talks: one for a bunch of talented high school students that are attending the SciTech challenge, and one for students (and others?) at the university of Stavanger. Excited!
Also, I'm sharing my day at the snapchat account of the physics department, so make sure to follow fysikkunioslo 🙂
Wish you all a great day!

2016 has so far been quite successful when it comes to working focused on my PhD project: My second article is starting to look like the real thing, and it's not that long until I can send it to my co-authors (I hope - everything takes more time than I think it should), and after that to the journal where we'll try publishing it. I've also finally managed to "go back" to working on some stuff that will hopefully be part of an article with my extremely talented colleague, Cecilie. Together with my office mate, Fabio, I'll also probably have what we need for a third/forth article.
The key word is focusing, and that's what I want to talk about now:
I'm unfortunately extremely "good" at procrastination! In addition I a have an "illness" where I sort of tell myself that if I haven't started some task after a certain time of the day (let's say it's already two 'o clock, and I have to leave early, at four, to get Alexandra in kindergarden) then I might as well just not do anything - extremely stupid of me! However, often it's just not enough to tell yourself to get a grip - I'v tried that several times, but it's just so easy to fall into the old, bad habits again :/ Luckily, there are apps to help you with this, and here I want to present my three favourite apps, that are helping me on my path towards my degree (and world domination, of course 😛 ):

1. Pomodoro

The Pomodoro technique is a time management method, where you use a timer to break down your work into intervals, traditionally 25 minutes, separated by short breaks. The "steps" in the method are as follows:
  1. choose some task to be accomplished
  2. set the Pomodoro timer to 25 mintes
  3. work on the task until the Pomodoro rings
  4. take a short break
  5. every 4 Pomodoros take a longer break

Of course, you don't really need this app - you can just start your own timer - but I prefer the app, since you keep track of what you've done (and what needs to be done), and it almost becomes competition with your self (for me, this is extremely motivating), and you learn more about how much (or little) time certain kind of tasks actually take, which is extremely valuable.

Personally I have 25 minutes where I work, and then a 4 minute break. Works like a charm!

More about the pomodoro technique HERE.

2. SelfControl

This is a very simple, but extremely efficient, app for your computer, that I just started using. Maybe my most important app, and it's already changed my life <3 SelfControl helps me not to procrastinate by blocking disturbing websites, mail, or whatever on the internet. You just set a period of time to block for, add sites to your blacklist, and start it - after you've started it you're unable to access any of the sites on your blacklist (no, it doesn't help if you restart your computer, or delete the app 😉 ).
So now I start every day with a quick trip to the websites that are on my blacklist, so that I sort of get it out of my system - then I start the app, and then I can work for hours without disturbing myself with stupid stuff on the internet.
More about SelfControl HERE.


NB: When I first started it, I thought you could block different sites for a different amount of time. That turned out to be incorrect. If you block for 4 hours, you block everything on your blacklist for 4 hours. If you want to override this app you have to re-install your operating system. In other word: it's quite efficient - just the way I want it to be 🙂

Health

Maybe this sounds a little silly, but I truly believe that the Health app on my Apple watch will help not to completely become a physical wreck as I try to finish this PhD work. (I may become a mental wreck, but that's another story.) The feature I probably like the most just now as there are many hours sitting in front of the computer, is that it makes me stand for at least one minute every hour (unless I ignore it, of course) - "standing hours":
The thing is that "fitness" isn't just about going to the gym, but also about being active throughout the day. So the Apple watch measures all the ways you move, and keeps track of when you stand up and encourages you to keep moving <3 Because it all counts, and it all adds up.
Just now I don't have time to go to the gym, but at least this app on my watch makes me compete with myself, and I try hard every day to fulfil my goals, in exercise (you should be active for at least 30 minutes every day), standing, and moving around. I'm not saying this is better than actually working out, but when you actually don't have time to go to the gym, this is awesome 😀

Hope you like my tips, have a great week everyone!

...or something like that.

Yesterday I sent what I had on my draft for this article I'm working on to supervisor-Sunniva - you, know, according to what I wrote last week I'm supposed to finish stuff and this draft should have been "finished" by Friday. Then guess what: it isn't! Even though I sent it away yesterday (2 days into this week, which is supposed to be about another article) there are so many questions about my results that I don't even know what to think. Today I asked everyone in our research group what I should do, and I basically got the answer that I have to do stuff again, several times, and just change some parameters and check if I can still reproduce my results...
Sometimes I hate science. Something about those 70% extra work for 5% extra quality - except just now it feels more like 90% extra work for 1% extra quality. Is it really worth it? Somewhere you have to draw the line, right...?
----------------------------------------------------------------
BTW: Alexandra did algebra for the first time today! After we went to the dentist this morning, she was so proud since we figured out that she had already begun to get a new tooth, and her front tooth is becoming loose, so we had to go and visit Anders who was teaching the quantum physics students before she went to kindergarden. And we were goofing around at the blackboard (there were only two students there so early in the day, and they were working by themselves at this time) and then she wrote an A and a B ("AB") on the blackboard and asked "what is A plus B?".
I told her she had to put a plus between the A and the B if she wanted to write "A plus B". And she did.
"If A is 2 and B is1, then what is A+B?" I asked her:
So she looked at me with this face telling me "please stop asking such silly questions" and instantly replied "It's three!"
Well, that made me a very #proudmommy <3

På lørdag var jeg i Folketeateret og så Mary Poppins sammen med mamma og Carina. Det var årets bursdagspresang fra oss til Carina, og forestillingen absolutt meget bra, på alle mulige måter, og spesielt imponert var jeg over Charlotte Brænna som hadde tittelrollen - fantastsik! Detssuten var det veldig morsomt å se flere "kjente" fjes fra min egen dansetid, på scenen 🙂
Det som derimot IKKE var noen god opplevelse, var hvordan enkelte folk tydeligvis syns at regler er for alle andre unntatt dem selv, og dermed oppfører seg...!
Ved siden av oss hadde vi feks en gjeng bestående av kanskje tre voksne damer, og det jeg antar var barna deres - i utgangspunktet ikke noe annet enn hyggelig med det. Så, etter at forestillingen er godt i gang, reiser en av damene seg opp, snur seg mot venninnene og barna, tar opp telefonen og tar bilde av dem. Med blitz! Det er altså helt mørkt i salen, og vi andre prøver å følge med på hva som skjer på scenen, men blir avbrutt ved at vi i prinsippet får en lummelykt rett i ansiktet. Den samme gjengen tok også bilder mot scenen, med blitz, flere ganger ila forestilling - rikitgnok hakket "bedre" for oss, siden vi da "bare" ble lyst i øynene sånn halvveis fra siden, men hvorfor gjør de det når alle har fått eksplisitt beskjed om å IKKE bruke blitz?!?
Det var også ganske mange som brukte blitz når de tok bilder senere i forestillingen.
Hvorfor tenker en del at "jaja, det er regler, men de gjelder selvfølgelig ikke for meg"? A**h****s, altså.
Men for å gjenta det; det var en veldig flott forestilling, og jeg syns det var kult at Folketeateret faktisk oppfordret publikum til å ta bilder ila forestilling, og bruke marypoppins-hashtaggen - men det er selvsagt IKKE kult hvis folk ikke klarer å oppføre seg som følge av det. Jeg syns det er utrolig merkelig hvordan noen bare ikke syns de trenger å ta hensyn til andre...
I går var det skikkelig kos dag for Alexandra og meg: Vi sov begge hos mamma og pappa fra lørdag til søndag, så først hadde vi skikkelig kosemorgen med mamma, og så dro Alexandra og jeg i det fine været innover til byen og Naturhistorisk Museum - siden jeg hadde lovet Alexandra en tur inn i Zoologisk museum. Fra giftshoppen måtte selvsagt den fine boken "Ida" av Jørn Hurum bli med oss hjem, sammen med en fin plakat med norske, giftige planter 🙂
dette ^^ er SÅ bra!
Etterpå gikk turen til Sagene Lunsjbar, før vi kom oss hjem. Dagen ble avsluttet med at vi begge to krøp opp i sengen til Anders og meg (han har jo vært bort i nesten en uke nå  men kommer hjem i kveld, da <3) og så filmen Malificent. Den kan absolutt anbefales - enten du er barn eller voksen! Såååå gøy at Alexandra har blitt så stor at vi kan se litt mer ordentlige filmer. Elsket tvisten de har laget i denne filmen om Tornerose, og ikke minst den onde feen; som kanskje ikke er så ond allikevel, når alt kommer til alt...;)
Nå er det tid for å sende avgårde artikkelen min til veiledere, og kanskje kan den sendes til medforfattere ila en to ukers tid? Det hadde virkelig vært noe!

Friday again - facts again <3
You know the drill, say no more:

  1. a neutrino is a en elementary particle
  2. a neutrino is not a neutron - neutrons are made up of quarks, and are thus not elementary particles
  3. there are three types of neutrinos: they're called electron neutrino, muon neutrino, and tau neutrino (they all also have an antiparticle)
  4. the name neutrino actually means "little neutron", but I have to tell that story another time...;) (In short: Pauli proposed that there should be a particle called a neutron, before the actual neutron was discovered. Then, what we know today as a neutron was discovered before the neutrino, and by that time the term neutron was taken, and this particle became a neutrino).
  5. neutrinos don't have any electric charge (so they are not at all affected by the electromagnetic force), and they're almost massless - but only almost...! They do have a tiny tiny tiny mass: the heaviest one is more than 4 million times lighter than the electron (the next lightest particle). Since they are so light, neutrinos move at a speed more than 80% of the speed of light at room temperature
  6. neutrinos are created in radioactive decay (like beta-decay), nuclear reactions (like in a reactor when a heavy nucleus fission, or in the sun when light nuclei fuse), when cosmic rays hit atoms, and in supernovae. Most of the neutrinos here on Earth come from the nuclear reactions that take place in the Sun <3
  7. every second, a trillion trillion neutrinos pass through your body, and since they do have (a tiiiiiny) mass, this means that there's a constant flow of matter through your body ALL THE TIME. Since their mass is so small, they don't add up to much mass - about 0.0000000000001 kg of neutrinos will pass through your body in a lifetime 😀 (If you add up the mass of all neutrinos that have passed through every single person who ever lived, over everyone's total lifetime, the sum is 0.15 kg)
  8. neutrinos are extremely difficult to detect, so you need really huge detectors if you want to try... For example, the OPERA detector (a good neutrino detector) consists of 1000 tonnes of mass to try to catch a neutrino, but even if this detector was a block of lead a light-year in length, you'd only have a 50% chance of stopping a neutrino!
  9. they are often called ghost particles, since they can actually change from being one kind to being another - an electron neutrino changing into being a muon neutrino changing into being a tau neutrino (this is weird: like if you went into a Mercedes and drove for a while, and then suddenly the car changed into being a BMW, and then when you arrived at your destination you were driving and Audi. W. E. I. R. D.)
  10. in 2011 neutrinos were sort of detected to move faster than light - which shouldn't be possible. Of course it turned out to be an experimental mistake, and we are still very very certain that Einstein's theory of special relativity is true <3

Bonus facts: According to my colleague, Cecilie, neutrinos fabulous 😀 Happy Friday!
