So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.

Crystal Field Theory
Tuesday. 2.21.12 4:14 pm
I finally got a library card for the university library. I celebrated by checking out a bunch of books on desert environments, crystal field theory, and aerosols. My first victim was the crystal field theory book, because I'm doing some free-lance spectroscopy on Mercury and I need it to figure out my positions on important issues, like whether Mercury is dark because it is covered in opaque titanium oxides or whether magnesium sulfates are what's goin' down there.
Spectroscopy is cool. Here's how it works. You've probably seen the shell model of the atom. A bunch of protons and neutrons crowded together in the nucleus, and then electrons buzzing around them in different shell levels above. Where there are groups of atoms, another atom can steal the electron from the first and they can become ionically bonded. It's a simplified model. Electrons actually have pretty complicated "orbitals", or regions in which they are most often found, within their "shells". Some orbitals are shell-like, others are elongated balloon-shaped loops. The electrons appear in different orbitals depending on how many electrons the atom has. Once the shell-like orbitals are filled, they move into the loopy orbitals, and so on. In a crystal lattice, many different atoms are bonded together in a repeating pattern. Because of the effects of neighboring atoms, the bonds are not always formed at ideal angles, and some atoms get stretched in strange ways. Sometimes their orbitals start to overlap, allowing electrons to move between them or to move between different orbitals in the same atom. Electrons also have different energy levels that they can occupy, and if they receive a jolt of energy they can enter a higher energy state. However, if the electron doesn't get exactly the right amount of energy to bring it into the next state, it can't go there. Too much or too little energy won't do the trick.
The energy that the electron needs to move into higher energy states can be imparted when a photon (a particle of light) strikes the mineral. Photons travel as waves with different wavelengths. Each wavelength corresponds to an energy. High energy photons are gamma rays and X-rays. Slightly lower energy are photons in the ultra-violet (UV) part of the spectrum. Next comes the visible part of the spectrum that you and I can see, starting with the highest energy (blue light) and ending with the lowest visible energy (red light). We have special molecules in our eyes which are suited for interacting with photons in this range of wavelengths, which allows us to see color. Just to the low energy side of what we can see is the infra-red. You can buy film and take pictures of things in the infra-red, which is actually fascinating because all vegetation appears bright white. We can't see infra-red light with our eyes, but we can feel it with our skin in the form of heat. This is why hot coals glow red-- they are emitting so much energy in the form of heat that some gets emitted in a slightly higher energy range: visible red light. ["Colder" stars are also red. Our sun is yellow, and very very hot stars are blue.] The infrared was discovered by William Herschel, an astronomer. He was measuring the room temperature and he noticed that if he measured red light coming from his prism the temperature went up. If he held the thermometer just to the right of the red light, it went up even higher. An invisible color of light, detectable as heat! He also discovered Uranus and several moons of Saturn and Uranus in his spare time (what do you do with your spare time)? At lower energies (and longer wavelengths) we run into microwaves. Finally, with really long wavelengths and low energies are radio waves. All these things are just other words for photons of various wavelengths, and together they make up what we call the "electromagnetic spectrum":
While a mineral may be bathed in the light of the whole spectrum (white light), it only absorbs photons that have exactly the right amount of energy to bump its electrons up to the next energy level. Depending on what elements are present, and where they are in the crystal structure, the mineral as a whole absorbs characteristic parts of the electromagnetic spectrum, mostly between the UV region and the mid-infrared. Much longer wavelength photons pass right through the material, while ones with much shorter wavelengths (X-rays and gamma rays) pass through the material until they run into something dense (like your bones). Most of the light in the right range is simply reflected. By measuring all of the light that gets reflected off of the mineral, you can see what it is made of, and how its crystal structure is arranged. Here is a hard-to-read graph of a bunch of common materials:
It's supposed to say, "feldspars, olivine, metal, and pyroxene". The horizontal axis is the wavelength of light, and the vertical axis is the amount of light reflected (usually compared to the amount of light that shone on the object, to get rid of the influence of the light source). The ones besides metal are very common rocks on the Moon. You can see that for each mineral there are characteristic parts of the electromagnetic spectrum where they absorb light. In the visible range, this defines their color. If they absorb everything but green, all of the green light will be reflected, and that will be the color of the mineral. If they reflect lots of red light, the mineral will be red. That is how the color of everything you see is made. By looking at rocks this way, we can tell what the Moon is made of just by collecting the light that reflects off of it from the Sun. So why are the absorptions deep, wide U's instead of very narrow blips where the energy level is just right? Well a major reason is because of heat. When something is heated up, its molecules start to vibrate. As the molecules in a crystal lattice vibrate, sometimes their electron orbitals start to overlap more or interact, reducing or augmenting the amount of energy required to jump between energy levels. So depending on how the lattice is vibrating, the atom can absorb photons on either side of its "ideal" wavelength, making a big U with the ideal wavelength at the bottom.
Here is the a spectrum for plants:
You can see that the least absorption is in the green part of the spectrum, which is why plants are green.
Sapphires can be many different colors depending on small trace amounts of metals that substitute into their structures:
And that is all of spectroscopy and crystal field theory in the space of a Nutang entry.

1. Kicked my friend's ass in Fußball. Yeah. He never saw it coming.
2. Visited the Parisian sewers and learned about where my water comes from and how it is treated, in addition to how water was distributed and waste water carried away throughout the ages. Saw (and smelled) actual sewage floating by.
3. Saw two people actually shooting up in the metro station. Holy shit.
4. My pastor challenged us to be more like Jesus and to reach out to the "untouchables" in the city of Paris.
5. My friend saw a homeless person lying face down on the sidewalk on a below-freezing day. She called the police and they told her she should poke him to see if he was still alive. She was afraid to poke him because of his crazy drunken homeless friend. The firemen came and picked up the guy and his friend. The next day they were across the street drinking wine again.
6. I did so much parkour that every single muscle in my body is sore and I can no longer walk or sit up. I thought getting in shape was supposed to make your body feel better?
7. I cooked some cookies in the microwave.
8. Tomorrow is Valentine's Day!
Actually I loooove Valentine's Day!
Hmmm... what else.... oh yeah, Obama's budget recommends shutting down the Mars program. No more exploration of Mars. =(

God the Finite
Monday. 1.30.12 3:50 pm
I have been thinking about infinity again a lot lately. Infinity... it just goes on and on and on forever! I usually think about it as a series of white numbers on a black background which come very close to the viewer and then as we pull away, fade into the vast reaches of empty blackness. Mathematically you can suggest infinity by putting an ellipsis [1, 2, 3...]. Everyone has their own way of dealing with infinity, I guess.
But infinity is a tricky beast, even for mathematicians. Stray infinities can bungle large model calculations. You can stay up half your nights chasing after wandering infinities. You can spend enormous amounts of time crossing out large sections of equations after you find that they go to zero, or trying to flip them over if they go to infinity. And there are the infinity over infinity cases. The infinity over zero. We call these "indeterminant", or "undefined". It seems silly that things in math can be "undefined". We made up math, didn't we? Can't we just "define" them? No, we can't, because math is really just a language that we use to describe the universe, and some things in the universe cannot be defined. These are the universe's way of telling you that you are operating out of your appropriate domain. ;)
Naturally thinking about infinity got me thinking about God, and how God is infinite. God isn't even a normal, hometown, countable infinity like aleph zero. God is like taking all of the infinite cardinals and adding them up to make a crazy super infinite cardinal that not only encompasses infinity many times over, but encompasses all possible infinities.
Human beings are by definition finite beings. We are finite in space, we are tragically finite in time, and the way in which we are able to perceive the world around is cripplingly finite. Just think about the Universe and how little of it we are actually able to see! Just think about our five senses and our lowly instrumentation and imagine all the other kinds of things that could be out there that we can't even imagine how to detect??
It seems logical then, that God would find us rather frustrating, if God had human emotions. God knows everything at all times and in all places. God understands everything and is everything. We are in one place at a time. We understand very little beyond what we have seen with our own eyes. We know what happens in our time and place, and then when we pass away our memories pass away with us. God has to constantly forgive us for doing things which are, to the all-seeing, blatently stupid and unwise. Every way in which we think about God is merely a projection of a vast infinity into something that we can understand better. We imagine that God looks like a man with robes and a white flowing beard. It is laughable to think that infinity could fit into a man with a white flowing beard. But how are we supposed to imagine God? Is this better ∞? Does God fit into a sideways 8? We each have a frame of reference, and we do our best to project God into it. One can hardly blame we finite beings for doing that.
Since God is everything and encompasses all experience, I sometimes wonder if the one thing that God hadn't ever experienced was being finite. After all, it is always very confusing to constrain the differences between Jesus and God (and the Holy Spirit, of course). How can three entities be one God? How can Jesus be the son of God, and also God himself? I think of Jesus as the finite manifestation of God. Since God is all things, he can't exactly make himself completely finite, or the universe would cease to exist. He would have to manifest himself in a finite being. You can't fit all of existence into the body of a man!
But how bizarre would it be to go from being Infinity to being a newborn baby? I suppose it would be good that you'd start out that way, because you would have so little awareness that you wouldn't even be aware of what you were missing. You'd have quite a few years to get used the Finite-game before you realized what was going on. I'm sure once Jesus got to an age where he was cognizant that he was the Son of the Lord, it was very weird to go around finitely, interacting with other finite creatures, eating food, seeing only out of two eyes, walking from city to city in a linear fashion instead of simultaneously being all places at once. That must have been very strange. Then, being alone able to grasp the power and knowledge of the Infinite, you would try to pass this information on the people around you. To you it would seem obvious and compelling, but to them it would seem at best cryptic, and at worst false. How frustrating would those finite creatures be! How narrow their minds! How short their sight! Death means nothing to the infinite! A body does not confine the infinite! But of course you could be nothing besides understanding, because you are Understanding itself, and you could be nothing but forgiving, since it was you who created these finite creatures to begin with.
I kind of think of dying as becoming one with God, and suddenly becoming aware of everything, in a way that is impossible while we are shackled by our bodies. It wouldn't be like we would "become" a God, or gods, only that we would suddenly be aware of the totality of existence, which would be totally mind-blowing if our ordinary human brain wasn't already dead.
Anyway, it's getting late, and my pathetically limited animated corpse requires 9 hours of unconsciousness per day for adequate function.

Life in General
Saturday. 1.28.12 4:35 am
Long General Update:
Sharkboy is BACK! I drunk-dialed him last night, intending to leave a silly message on his voice-mail, but I got the real thing! Then it was awkward because he was really sober and hanging out with his parents. Haha. But we talked for a good while and it was great to hear about his trip.
Wine is horrible. I like how everyone always says, "Oh, this wine is so smooth, it goes down really easily." By this you mean that the wine that you usually drink goes down like burning gasoline and you are surprised and delighted when you taste a wine that you are physically capable of swallowing. But I'm in France, and drinking gasoline is part of the territory. Luckily a "delicious", "smooth" wine in France is like 80% of the cost of a comparable wine back home, so my strategy of poisoning myself to gain the social acceptance of my peer group isn't too hard on my pocketbook.
Last night I went out with some random french people including my co-worker and his girlfriend. I meet up with his girlfriend every Friday at a cafe. We drink hot chocolate or soda and practice speaking in English and French. She's actually really cool and I like her a lot. She was apparently talking to a friend of hers in Japan who said that she's having lots of fun because even though she's alone people invite her out practically every night. My friend was inspired by the story to invite me out with them because I was similarly alone in a big foreign city. Aw.
We went to a little bistro and drank red wine and ate an assortment of cheese and a charcuterie plate (assorted meats). They said that you really couldn't get much more french than that and that I should take a picture. I didn't, because I'm too cool and they were joking, but I wanted to.
Last week I had an "American" dinner for my friends. My new canadian best friend and I went to the American grocery store and bought a bunch of delicious items and then fixed them up for our friends. We wanted to serve things that were very American and that our friends hadn't heard of before. We ended up having Jell-O shots as an aperitif (served in champagne flutes, how classy!) We passed around a root beer so that everyone could try it, and to my great surprise not everyone hated it! For appetizers we had potato chips and sour-cream and onion dip, Nacho cheese Doritos, and little peanut butter and jelly sandwiches that I cut into fours and garnished with toothpicks. Everyone was sidetracked for a while admiring the jelly container, which was a squeezable type with one of those lids that dispenses jelly in a flat sheet so that you don't need a knife. I was so proud of the technical accomplishments of my fellow countrymen. For dinner we served a chicken and stuffing casserole made with cream of mushroom soup and another strange casserole with three layers: cranberry sauce, bacon, and mac n' cheese. The canadian said that she'd had it once at a restaurant outside of Boston, and while it wasn't strictly traditional American, it combined three things that were traditionally American, and it tasted fucking DELICIOUS. Holy shit it was so delicious.
After our guests had decimated all of these things, the Eiffel Tower started sparkling, and I told everyone that they should come and take a look. Everyone started moving from around the table, when suddenly my friend bumped the table and the entire thing collapsed. Considering that my tabletop is a giant slab of incredibly heavy wood, the collapse was catastrophic, breaking nearly all of my dishes and glasses and spraying onion dip, Doritos, and red wine all over the room. We were lucky that most of the guests had gone to look at the Eiffel Tower, or there could have been some serious injuries. Luckily we were finished eating, and the dessert was on the counter in the other room. For dessert we had cupcakes and a big cake with funfetti icing. The theme of the evening was "dinner from a box", so naturally we made nothing from scratch. Someone else brought Chips Ahoy, and the europeans brought macaroons and champagne and wine, so our dessert was a mix. Everyone was enchanted by the funfetti icing, and even though they all laughed and said they were full when I cut the cake after the cupcakes, they all ended up taking an extra piece anyway. The best part of the cake was that they only ate a third of it, so over this last week I have been pretty much eating the rest. We had a German, an Italian, an Ecuadorian, a Frenchwoman, a girl from La Réunion (french overseas territory in the Indian Ocean near Africa), a Canadian, and an American (me).
Work is going ok. We are working on an important project, and the only outstanding part is my part. This is naturally stressful, since I am new to this field and not well-equipped to solve any of the many problems that I encounter. I was really starting to feel like a huge idiot, but my director came in and sat down and explained a lot of things to me, which helped a lot. Now instead of watching random numbers go by on the screen I feel like I can watch numbers and see the atmosphere breathing. That's pretty cool. Still, everything I try to fix the problem doesn't work, and it gets me down. It always seems like the other post-docs are progressing at a faster rate than I am. I also occasionally see the whole group having a meeting that I wasn't invited to. They have been testing out Python as a potential better programming language and I'm the only post-doc that wasn't asked to participate even though I've actually taken an entire class in Python programming.
At the end of my PhD I really had everything together, and I was at the top of my game. Now it's like I'm a freshman again and I know nothing. I know that it's better that way because I'm learning, but it's tough.
It's nice to be able to balance challenges areas with comfort areas. Right now I feel like I am living my entire life in a challenge area, where I'm an idiot at work because I'm not an atmospheric scientist, and I'm an idiot in every other arena of life because I'm a foreigner. [If you are ever feeling stressed about dealing with repairmen or cable companies or the government, stop and thank your lucky stars that you at least get to speak in your own language!]
For this reason it was nice to talk to my coworker, who while French, is also from outside the field. We finally talked about how frustrating it is to work with our current model and how we're making hardly any progress. He told me that he's always having to tell our director, "Everything you just explained actually means nothing to me," and the director has to start all over again. I had an idea to make the model more idiot-proof and I proposed it to the group but nobody ever got back to me. My coworker told me that he thought it was actually a really great idea. Thank you! I also talked to my director and we determined that the problem that I'm having is actually really complicated, instead of just something stupid. That's bad news for the model, but at least it makes me feel better for not being able to figure it out.
I went for a free tour of the Louvre, and I was the only one that showed up, so I got a private free tour. The lady was really nice and she said she didn't speak English that well so I said that she could give the tour in French. She asked where I was from and I said "the USA," and then she said, "Oh, well then I guess I should give the tour in English." I said that it was really ok so she gave the tour in french. She spoke slowly and I already knew a lot about greek mythology and european history, so she was easy to follow.
Hmm... what else? Ah yes, there is a giant mystery novel unfolding in the hallway of my apartment building, but that is complicated so I will leave it to another entry.
Someone I know on Facebook posted this photo:
And for some reason it made me soOOooo homesick for the USA. Nothing better than a little American BBQ with babies. =)
Wednesday. 1.25.12 6:24 pm
Captain's log, stardate 41147.3. It has been at least a million days since Sharkboy left for Patagonia. The crew maintains that our sense of time has been distorted by the massive black hole that has been left in his absence.
Since his departure we have been drifting aimlessly in space. Just kidding, we have been dining out with friends, learning parkour, and getting free private tours of the Louvre. We have also been eating delicious cake. But it still feels like drifting aimlessly in space, especially because we forgot when he is supposed to come back. He did promise to catch a fish in the captain's honor.
France, the final frontier. These are the voyages of the starship Zanzibar. Its 2-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
