Einstein’s letter
"Could nuclear weapons save the planet?"
Facts on Friday (we pretend Monday = Friday) – EXPERIMENTS!
- The material we want to study can be almost anything - for example uranium, gold, nickel, molybdenum, iron, dysprosium, thorium or plutonium (these are just some examples of what we have experimented with the last couple of years)
- We make a tiny foil - a target - from the material (almost the size of a small coin), and put this inside all of our detectors
- There are always at leas two types of detectors for the experiments: Sodium Iodide detectors (they measure gamma rays), and Silicon detectors (they measure particles)
- The Sodium Iodide detectors are called CACTUS (cause it really looks like a cactus) <3
- Sometimes we use more detectors than the gamma detectors (CACTUS) and the particle detectors - for example fission detectors (we used that for my uranium experiment, since uranium-233 fissions like crazy 😛 )
- To study the nuclei in the material we bombard the target with tiny particles; protons, deuterons (a proton and a neutron), helium-3 (two protons and one neutron), or helium-4 (two protons and two neutrons - same as an alpha particle 😀 )
- When a particle hits a nucleus in our target material, the nucleus gets some extra energy (sort of like it gets heated); then a particle goes out (it can be the same that went in, or it can be another one), and the target nucleus cools again, by sending out gamma radiation
- The different detectors will detect the different kind of stuff that comes out from the reaction in the target: the gamma detectors detect the gammas, the particle detectors detect the particles (protons, deuterons, helium-3, or alphas), and the fission detectors detect fission - the detection of all these thing are what we talk about as our data
- Data from the experiments we are performing in Oslo (like my uranium experiment) is typically 10-100 Giga Bytes - so it's kind of a lot
- To sort all of these data we need codes/programs that go through everything and checks if there for example was a particle and a gamma that came out of the target at the same time, or maybe it was a particle and a gamma and a fission product, and what were the energie
s of all this; the particles and the gammas - on the lucky side I don't have write theses sorting codes from scratch, on the other side I have to try to understand someone else's code and logic, which is not always very easy (when I don't understand I'm always sure it's because I'm stupid :/ )
To program or not to program?
Tomorrow I have to be better! Not because it in any way is wrong to spend time on trying to work on my programming skills, but because I have deadlines, and right now there is unfortunately no room for anything else than what HAS to be done... Why does everything take so much time, especially things you need to learn like almost from scratch?!? *frustration*
My PhD ("dumbed down")
- Nanoparticles are weird and I accidentally made a bomb and electrocuted myself.
- Inpatients with schizophrenia are happier and socialize more in the context of a music listening group. It was obvious before we began the project and we learned nothing.
- Little things stick together. Here's a slightly easier way to calculate their stickiness.
- This protein looks like it might contribute to asthma. Oh, turns out it probably doesn't.
- Two proteins touch each other in a specific place in the developing heart. No idea if it's important for anything.
- People sometimes think about animals as if they're people. People like those animals a little more than regular animals. Except when they don't. I can't believe they gave me a PhD.
- Sand washes away, don't build important stuff on it.
Jonathan: "All models are wrong, but at least now we can confirm they are wrong much faster"
Veronica: "Can electrons surf on an electric wave? Yes"
Kyrre: "How many sparks do we see when we push ridiculously strong micro waves through thin vacuum tubes? (And how do they work?)"
Thorium is a nice thing for a nuclear fuel, but you get the f****** uranium-232 from it, and it makes everything s***. Now we kind of know a little bit more about it. Which is just sort of true.
Fuerteventura
- TEDx - thorium and weapons and stuff (and maybe Titanic...;) )
- TALYS - finish it all (!)
- My paper - make the tables and the figures, and place them where they are (probably) supposed to be
Fusion on a Friday
- Fusion is when two (light) nuclei merge (fuse) together to form a heavier nucleus - it's the opposite of fission. (Read more about fission HERE and HERE)
- When very light (atomic) nuclei, like for example hydrogen and hydrogen, or helium and helium, or hydrogen and helium, fuse, they produce energy 😀 😀
- The sun (and all other stars in the universe) get their energy from nuclei that are fusing (like hydrogen and hydrogen, or helium and helium, or hydrogen and helium - or other nuclei)
- The different elements in the periodic table (up to iron) are made from fusion in stars/suns (but the heavier ones, like gold, or thorium, or uranium, for example are made in the big explosions in space)
- If you check the mass of the nuclei you start out with, and the mass of the nucleus you get after the fusion (so, checking how much they weigh, that is), it weighs less after the fusion than before - this extra mass that suddenly is "gone" hasn't really disappeared, but it is released as energy <3 E=mc2 <3
- It would be really really cool if we could produce energy from fusion, like the sun is doing - but so far we can't do it...:/ (We manage to get nuclei to fuse, but we use more energy than what we get out.)
- Since nuclei is made out of protons and neutrons, they have a positive charge, and therefore they REALLY don't want to get so close to each other that they fuse - it's like trying to push the same pole of two extremely strong magnets together; it doesn't work (but it does work in the sun, since it's very hot and very high pressure, so there the nuclei just fuse all the time :D)
- I think it's really fascinating, and a little weird, that you get all this energy from two opposite reactions - either by fusing light nuclei, or splitting heavy ones... <3 nature <3
- If you managed to make a fusion power plant, you wouldn't have the problem with radioactive waste, that you get from a fission power plant (a normal nuclear power plant) - so that's very nice...
- ...however, fusion is hard :/ We don't manage to do it (without putting more energy in than we get out) yet; but who knows what will happen in the future...? 😉
Love song for nerds (*heart*)
See/hear the song HERE (seriously, DO IT ;))
Here's the lyrics - what do you think?
If I didn’t have you, life would be blue,
I’d be Doctor Who without the Tardis,
A candle without a wick,
A Watson without a Crick.
I’d be one of my outfits without a Dick-ie.
I’d be cheese without the mac,
Jobs without the Wozniak.
I’d be solving exponential equations
That use bases not found on your calculator,
Making it much harder to crack.
I’d be an atom without a bond,
A dot without the com,
And I’d probably still live with my mom.And he’d probably still live with his mom.
Ever since I met you,
You turned my world around.
You supported all my dreams and all my hopes.
You’re like Uranium 235 and I’m Uranium 238,
Almost inseparable isotopes.
I couldn’t have imagined
How good my life would get,
From the moment that I met you, Bernadette.
If I didn’t have you, life would be dreary.
I’d be string theory without any string.
I’d be binary code without a one, Cathode ray tube without an electron gun.
I’d be “Firefly”, “Buffy” and “Avengers” without Joss Whedon.
I’d speak a lot more Klingon:
Heghlu’meH QaQ jajvam.And he’d definitely still live with his mom.
Ever since I met you,
You turned my world around.
You’re my best friend and my lover.
We’re like changing electric and magnetic fields:
You can’t have one without the other.
I couldn’t have imagined
How good my life would get,
From the moment that I met you, Bernadette.
Oh, we couldn’t have imagined
How good our lives would get,
From the moment that we met you, Bernadette.
