I'm a Prog-Rock-ologist getting his mind blown by early Floyd and King Crimson while drinking a few beers. Does that count? :)
I´m a chemist and my investigation involves the thermal analysis of the decomposition of the type 1 collagen and its interaction with hydroxylapatite present in bone samples of prehistoric animals like mamoths.

um cool what is that? I mean Collagen I get and the big word is about minerals of in the old bones. But what are you looking for?
I´m studying the interaction between these two substances to see if we can correlate the nature of this interaction whith some of the caracteristics of the specimen, like its gender o how old it was. This study is useful because you require very little of the sample and the technique could be applied later to human bones and make it easier for the detectives or the anthropologists to identify human bodies. We work in conjunction with the INAH in Mexico (INAH = Instituto Nacional de Antropología e Historia or National Institute of Anthropology and History).

How close are you to finding correlations? Does it help in other ways such as determining maybe how long ago it died?
Not quite as close as I would like, mostly because our samples aren´t always as good as I need or they don´t even come from the same type of animal. I said "prehistoric animals like mamoths" but we also have samples of hadrosaurus, sharks, etc.
About the other question: yes it does, and with results on par with other tests (like carbon-14)
INAH in Mexico (INAH = Instituto Nacional de Antropología e Historia or National Institute of Anthropology and History).Freaken' awesome museum. I love the rain-fountain on the roof of the courtyard.
You are talking about the Museum, and although I would be VERY HAPPY to work there, the Institute is another thing.
And yes, it´s freaking awesome :D
Cool thread, I'm only an undergrad. at the moment, though I should be a P.H.D. physicist in the quantum field theory field in a few years! (Well, like 5, *sigh*). Still though I have to publish stuff to get my Masters and PHD, so I'll be contributing sooner than that!
I'm a Prog-Rock-ologist getting his mind blown by early Floyd and King Crimson while drinking a few beers. Does that count? :)Not quite. Drink a stout one for me though and crank up the Crimson.
Don't forget Canada's best power-trio!

Is there a good 'beginners' or 'dummies' book on quantum field theory for the layman out there you can recommend?
Lets define what science is and is not.
I think science begins with observation, and ends with weapons to fight aliens.

Back in the day I was all in favour of the Choas Theory. Then as I thought more about it I concluded that given enough information, one could predict the outcome of any situation. Now this quantum field theory comes along and changes all that.
How am I suppose to rig Plinko on The Price is Right if quantum theory tells me I can't truly know whatever it is that I can't truly know according to quantum theory?!?!?*
*That last sentence probably makes no sense to the reader but in the dark recesses of my mind it makes perfect sense...
Funny though! The head of the Theoretical Physics Department here is Danny Heffernan, who made many contributions to Chaos Theory in ~the 80's~.

Hmm, I had it lucky you see, the science soc here has regular and engaging talks, and my girlfriends older brother is a QFT PHD student, who is a) very, very intelligent and b) really really good at explaining difficult concepts.
So I'm quite spoilt in that regard, I'd be very wary of Wikipedia, because to get it you have to go way back and understand its evolution from the start.
I'll look around and ask somebody.
[EDIT]: A very good book to learn basic Quantum Mechanics, a start if nothing else, is a book called Understanding Quantum ~something~ by Rahamurti Shankar, but that's not really what your looking for.[/EDIT]

Saw that on Amazon, but that came out in '94 and the least I see it for is $42. Not exactly what I was looking for, but thanks. :D

Haven't looked at any of them, though. And my only formal exposure to quantum physics was when I sat in on on a friend's elective module while studying genetics.

Now that's what I'm looking for. Videos would be harder for me due to being hearing impaired and sometimes reliant on captions. Thanks, Paul.
Theoretical physicist looking into dark matter and how we might produce it at the LHC under Geneva. Keeps me out of trouble when I'm not drawing maps...

Best. Show. Ever.
Saw them do 2112 in it's entirety. 2 full hours of music with only a small interlude. Blew the roof off the place. And I watched in awe the whole time without any booze or, um...herbal supplement and still had a great time.

Hawkwind rules! And don't get me wrong, microbiology too :)
I think science begins with observation, and ends with weapons to fight aliens.
I'm pretty sure Newton and Euler had secret (black) side projects to invent sciences for use in combating aliens.

Theoretical physicist looking into dark matter and how we might produce it at the LHC under Geneva. Keeps me out of trouble when I'm not drawing maps...Two questions:
1. What are you gonna do with the dark matter?
2. Do you have any Illuminati working there?
Dark Matter and Illuminati can not co exist in the same room. Fnord
1. Watch it disappear through the wall and figure out what it is. Tell people repeatedly that we can't use it to blow anyone up. Figure out what it tells us about the beginning of the universe and how many dimensions we live in
2. :) Sadly not. Nor does CERN have a space plane, much to my undending dismay.

Now that is awesome. Which set of sensors is that experiment running on, e.g. ALICE, etc.?
It's really CMS and ATLAS that will see hints if they're there to be seen. If we produce dark matter at the LHC it will leave the detector without being seen - after all, dark matter streams through the earth and yet our detectors haven't seen it yet. However the detector will be able to see how much matter is missing from the signal, and hopefully will spot the heavier particles that decay to the dark matter within the detector. From those two separate clues we'll be able to tell quite a lot about the nature of the elusive dark matter that has disappeared out of the detector. This, combined with light from the early universe and experiments looking for dark matter in space, will help build up the jigsaw of clues that tell us about the new theory of physics that will take the place of the Standard Model.

]When the black hole dances toward Earth, its light is blueshifted — meaning it has a shorter wavelength. The team identified waltzing pairs by looking for instances when one black hole was blueshifted and the other redshifted.
I thought and excuse me if I am wrong, that black wholes were um black?
If they are talking xrays I can understand since there does seem to be a stream of xrays coming from them but light?

You should be drawing maps all the time!

Maybe I should have said visible light which is what the article made it sound like.
Black holes don't emit light - but they often have accretion disks. As dust is pulled into a black hole it gets hot and emits light. They might be taking about that. - do you have a link to the news article?
@Hugo - :)

Sometimes they simplify things so the common person does not get confused, and that confuses things. I think this is what happened.
Ah, yes. It's the accretion disks that are giving off the light, rather than the black holes themselves. As they're talking about supermassive black holes at the center of galaxies, the system is large enough that the black holes, *and their accretion disks* are orbiting each other. Therefore you see the light from the accretion disk being re shifted or blue shifted depending on whether it's traveling away from you or towards you respectively. It's almost certainly not going to be just visible light - they'll have been looking at the whole spectrum to get a good measurement.
It's not my work, but I just dropped a couple hundred MBs of content into Medline and JSTOR. Hey, someone's got to move those electrons.

Have you solved the issue of Superpositional drift for Elements subjected to change in possibility? Or are you still working on the assumption that the distance between two points is not change in possibility, but rather Space and Time...?
Among the Paizo Messageboard regulars (and irregulars), I'm aware of a couple of scientists - a geologist & a biologist. Are there any other scientists frequenting these boards? Are you folks doing anything really cool you'd like to share?
I am an aquatic ecologist. Most of my research is on freshwater mussels, of which there are roughly 300 species in North America. I also work with fish quite a bit. Anyway, essentially I am a field ecologist that examines the effects of human activities on the aquatic environment.
