Publisert 2 kommentarer til Lazy Sunday, crazy week
This week will be crazy - at least the three first days... Tomorrow and Tuesday will be the last two days with meetings with the Ludvigsen committee - after Tuesday, everything is supposed to be more or less ready for the Minister *feeling pressure*. Then, on Wednesday I will give a talk at the Women in Tech conference in Oslo (program HERE). The talk is not (a 100%) finished yet, and naturally I'm feeling pressure here too. My talk is called "Hva har kjernefysikk og rosablogging til felles?" (what are the similarities of nuclear physics and girly blogging), but I think I will have the subtitle from my talk at Le Rossey in November; "why science should be more pink" - I'm really excited and a little bit scared, but I think (hopefully) it will be ok 😉
Thursday and Friday have to be 100% dedicated to SCIENCE; I'm so close to knowing what the gamma energies of my ALFNA matrix are now. You know that feeling when you've been working on a big puzzle, and suddenly you only have 30 pieces left? That's about how I'm feeling right know, and in a way I wish I could be at the office, working on those last 30 pieces tomorrow... However, that's life, and I think Thursday and Friday will be some very productive days <3
------------------------------------------------------------
We have spent a fantastic day at Sognsvann today - with Anders, Joakim, Lise, Alexandra, and me; here are some snaps from a great day! (Yes, you're right; this is how I look without any makeup on...I feel naked 😛 )

I admit it; I'm feeling stressed.
Our nuclear physics workshop/conference here in Oslo, where I'm supposed to give a talk (and show RESULTS) is only three weeks away, and my gamma detectors are not yet calibrated. Don't get me wrong: it's not like I'm giving up (I don't think I'm a quitter), but I know there is work to be done. I think I have to go through my plan, and check how I'm doing with my milestones/goals - I'll give you an update tomorrow <3
--------------------------------------------------

I think I could have worked faster, but I really really want to understand this - and make sure I make NO MISTAKES! So today I made this table, and the next step is to try to find the different gamma energies from the table and place them in the plot...hope my "prework" will pay off, and that tomorrow will be successful day 😉

Good morning from the airport everyone!

I'm blogging from the gate at Gardermoen airport - on my way to Trondheim to give a talk about nuclear power (it will actually be more like two talks: one about "myths" about nuclear power and radiation, and one more technical about thorium as a nuclear fuel) for a bunch of science teachers *excited!* 😀
Just "stopping by" to say Hi, and wish you all a great, sunny (at least the weather is beautiful here at Gardermoen) day, and to tell you about the talks I'll be giving before summer - in case anyone's interested in coming 😉
  • May 6th: The "Women in Tech"-conference 
  • May 12th: Popular talk about nuclear power and maybe some thorium
  • Week 21: About the progress of my uranium-233 experiment - at the Oslo (nuclear physics) Workshop
  • May 26th: The future of nuclear power and thorium and what's really "the thing" about Norwegian thorium - INSEAD Alumni 
  • June 1st: Popular talk about nuclear power and thorium
So if you're interested, the two talks in pink are open to everyone...;)

Publisert Legg igjen en kommentar til Q-value
Today I've made this table (with my new favourite: this calculator 😀 ):
So this beautiful table shows the different Q-values for the different reactions that go on in my experiments (oh, yes, there's beryllium and there's carbon and there's oxygen there - even though it would've been nice if it was only uranium...).
The Q-value tells how much energy that is released in a certain reaction: for the first reaction, for example, the Q-value is 4620 keV, which means that when a deutron hits a uranium-233 nucleus, and a proton goes out of that reaction, around 4600 keV (energy) is released ;). If that same deutron hits an oxygen-16 nucleus instead of the uranium-233, and a triton (instead of a proton) is released, the reaction absorbs energy instead of releasing energy: 9406 keV to be (almost) exact...
I also, finally, submitted my application about changing my theoretical curriculum for my PhD degree 😀
----------------------------------------
It's beautiful at the University these days, btw - don't you agree? Love blossoming cherrytrees:)

This is so the story of my life these days...and on top of everything, the apartment is a mess - since we're trying to make it fit two adults instead of one. Not that I'm complaining about that - I love it - but it takes time 😛

Anyway; guess that Hofstadter's Law applies to a lot of areas in life? For me right now it's mostly science and living situation stuff 😉

Ok, so my absolute favourite nuclear reactor is....
...the SUN! Of course.
And I simply LOVE that because of the fantastic nuclear fusion reactor, just about 8 light minutes (149 600 000 km) away, I can wear open toe stilettoes as my lecture shoes - as I did today <3 <3 <3 (Love these shoes too, btw; aren't they pretty?)
Anyway: I think it's so funny that solar power really is nuclear power, since the sun is a gigantic nuclear power plant (or continuously exploding atomic bomb...:P), that gets its energy by fusion of really light nuclei, like hydrogen and helium.
It's soooo cool that you get an energy release when light nuclei fuse to form a heavier one; as always it's because mass and energy are really the same (Einstein again), and the two light nuclei weigh more (when you add them up) than the heavier nucleus you get after they fuse. The "lost" mass has been converted to energy 😀
-----------------------------------------------------
Ok, now I have to run, to get to an interview - I just had to say hi and tell you about my favourite reactor.
Do you have a favourite (nuclear) reactor?

Dear dear readers!
I´m so sorry about my "not being as active as I really want to"-behaviour here at det blog these days, but I´m trying to be a good PhD student and a good mother and prepare talks and fix the apartment and everything...and of course there's something about my internet connection at home these days - meaning, there is no internet for me there (Anders' Mac is fine, but suddenly it's not possible for me to connect) :/

-----------------------------------------------------------

Anyway; hope you understand, and please follow me on Instagram and Snapchat - I've just started to "figure out" Snapchat (haha), and I'm sharing pictures from everyday life at the University (and then some - Alexandra, for example 🙂 ).

I'm @sunnivarose on Insta and Snap, of course 😉

No, I'm not talking about myself, but supervisor-Sunniva, of course 😀
This is what we've looked at today - the ALFNA matrix, and we've tried to figure out some of the gamma peaks that we see (in red); oxygen-17 and beryllium-10:
I just figured out that she's going to South-Africa tonight (for an experiment at iThemba lab), and I almost panicked, because I really need supervision now, since our workshop/conference is soon coming up (early May), where I have to give a talk about the results from my experiment :/ She promised we could Skype, though, so I'm hoping that will work...

Publisert Legg igjen en kommentar til change compile sort check
I'm not dead, I've just tried to be a good PhD student the last couple of days (and it's been some loooong days)...the title of this post and these pictures more or less tell the entire story:
- change (the sorting code)
- compile (don't forget - like I did yesterday )
- sort the data files
- check the results
- repeat 😉
-------------------------
Tonight I even had sort of a nightmare about my thesis defense: for some reason I didn't start making my trial lecture before 30 minutes before I was going to give it - and the theme of the trial lecture was simply "chlorine" ( and in my dream this was a molecule consisting of chlorine and some other atoms), then I realized I wasn't wearing any shoes (I was barefoot), and there were so many people that had come to see the defense, and then one of the opponents ran away and the other had to go and get him. Luckily I woke up before I started to talk!
I was really stressed when I first woke up, and then I was pretty relieved when I realized it was only a dream - and that my thesis defense will be nothing like this dream. I'm actually planning on having fun that day - when it comes 🙂
Hope you all have a beautiful Friday ❤️

Hei alle, og spesielt hei til alle dere som går siste året på videregående, og enda ikke har søkt på høyere utdannelse <3 I morgen er søknadsfristen, og i den sammenhengen vil jeg både minne om at nå er siste sjanse, og dele et utdrag fra et intervju jeg hadde med NRK for et år siden - om hvorfor jeg valgte å bytte helt fra ballett til å studere fysikk 🙂 (Syns riktignok jeg blir fremstilt som litt vel negativ til "nerdene" - jeg er jo absolutt nerd selv, selv om jeg kanskje er litt over snittet opptatt av "overfladiske" ting 😉 )

Sunniva Rose slenger de lange beina på skrivebordet. Før trodde hun at de skulle bringe henne til ballettscener. Men nå sliter hun dem ut på linoleumet på forelesningssaler og på atomlaboratorier på Universitetet i Oslo.

Men det var ikke tall, formler og kjemiske reaksjoner hun drømte om som tenåring. – Hva fikk deg da til å velge fysikk som studie?

– Den veien var lang. På videregående gikk jeg ballettlinjen, men da jeg var 17 år forsto at jeg aldri ville bli den beste ballettdanseren, forklarer hun. 

– Så jeg tok en helomvending og gikk andre klasse på videregående skole om igjen, og valgte matte, fysikk og kjemi som spesialisering. Alle mente jeg burde bli lege fordi jeg hadde så gode karakterer. Men det synes jeg er feil fokus, sier hun.

– Hvilke egenskaper er nødvendige for å bli en god fysiker?

– Man må være nysgjerrig, systematisk og opptatt av logikk. Hvis du er typen som ser på naturen og undrer deg over hvordan alt henger sammen med alt, så kan du trolig bli en god fysiker. Dessuten tror jeg det er viktig å ikke slutte å leke og forundre seg over livet og verden. Jeg leker hver dag!

– Hvilke råd ville du gi unge som i dag lurer på om de skal studere fysikk?

– Det er en fordel å ikke slite med matematikk. Hvis du har interesse for realfag er det lurt å fordype seg i matte, kjemi og fysikk på videregående. Jo bedre du er i matte, dess lettere vil du få det. Og du kan bli god realist selv om ikke flink i matte, sier hun.
– Er du motivert, så kjør på. Ikke nøl. Men vær forberedt på at overgangen fra videregående er knallhard. Tempo på universitet er mye høyere enn på videregående. Jeg følte meg kjempedum i starten og fikk dårlige karakterer, men jeg tenker at jeg lærte mye av det. Jeg gikk mange runder med meg og var nær ved å gi opp. Jeg fikk det jeg kaller studentsyken, men så tok jeg grep og lyktes.
– Dessuten er det viktig at du som fersk student prioriterer å bli kjent med andre, engasjere deg i studentforeninger og få et sosialt nettverk. Uten venner her på Blindern føler man seg fort liten og dum.
