A talk on giving talks (by sarah)

I went into college on Monday and met up with my friend David for a coffee before the lecture which was nice even if I was being a bit a flake - and his supervisor appeared and he felt too guilty and went back to work :/

It was odd being around the IC campus once more it was like being transported back in time about five years but into a parrallel universe where everything was just slightly wronge - like the walkways gone and is now in the libarary and there is a cafe in the the libary - why oh why couldnt they have had that when I was there - thats what me and Ella always said it needed - that and 24 hr access!

Anyway I then headed over to the UCL campus and turned up to the lecture room and panicked that there where undergraduates in there with microscopes and the like doing some petrology.

But then Martin turned up and we went in anyway - talking loudly and scaring all the little UG's away 🙂

Then Franky turned up and a girl from another course (Chemistry related I think) - the lecture was on how to give our 15 minute talks next week - first off eeeek eek eek - what do you mean next week? Panic! - then - wow they actually managed to give an hour lecture on giving a fifteen minute talk :/

At the end we found out that we really are down to 3 - the other moon girl has left and one of the other guys has changed to a PhD.

That is one hell of a drop out rate - maybe its the part time thing - we all have other lives and this is the thing we 'fit-in' when it is really a full time thing in itself.

I feel abit said that we are down to three - and I'm still not properlly registered :/

A Sense of Deja Vu (by sarah)

Alaric left for London yesturday to fly out to Santa Clara for a MySQL conference thingy and within an hour of him leaving my mother asks me if I knew a neighbour - I say yes and then ask why.

She said Barbara had asked her if she had known Linda and when she had said no Barbara had just walked off.

A sinking feeling begain in my gut - Linda was a very sick woman and I was awere she hadn't been to visit for a while but then she always had spurts in hospital and stuff. So I went over to talk to Barbara and she said 'you didn't know my friend Linda but she dies yesturday.' I've been making preserves and giving them to Linda for about two years and her and her husband used to come found for a lot of meals with Barbara - we tracked down foods she'd had when she lived abroad that she couldn't find like tofu and balsamic glaze.

So I had to explain that we did know her and then deal with the fact that this was actually one of Barbara's closest friends in the village. She was very sick and apparently refused the dialysis that could have kept her alive for a bit longer 🙁

After that I found out from Barbara that some terminally ill children are coming over in May to visit and she would like it if me and Alaric could be around to take them on an outing.

I came back to the Bakery feeling troubled - I had one thought I could not shake - please god don't let this be another September. Family friend/villager dying - that was how it all started.

September - the catastrophic month - four funerals, three in one week.

Fear clinched at me - who was I going to loose? Who that I felt deeply about would be leaving me next? Stupid and idiotic, I fought the stupersticous thought. A pattern repeating, encircling me. Alaric away on business and the messages of death begin to arrive.

Insane thoughts - edged with tears for Alex once more.

Obviously no more such messages arrived but Barbara came over later that day to give me some cool gardening bits she had been sent for free/by mistake and didn't know what to do with and some recipies she'd cut out for me.

She also bought round a job advert - something she had cut out a while ago and forgotten to give me but seemed to be the perfect job for me - geologist, very local - Birdlip - walking distance really. It was the company Alex was working for when Alex died.

I saw the name of the company and thrust it back at her, 'no thats Alex's job' I cried - I don't even know if it was I just panicked as soon as I saw the company name.

'Oh he's that close is he?' Barbara asks - then she went on to ask why he hadn't been round for dinner or to visit recently. I couldn't say anything.

She carried on talking and then said - 'oh this company is the one that was involved with that poor boys death in that trench is it?'

I managed to say, 'That was Alex' and then ran out the room and locked myself in my room and cried.

Jean came and found me and 'hugged me better'. I still feel just so raw about it all. I'm wondering how often this is going to happen 🙁

Using the Electron Mircoprobe (by sarah)

Today I went into the lab once more and place the lunar sample into the machine - this time instead of blasting it with x-rays to get element maps I was picking out specific points to hit with an electron beam and see what they are made off.

First off we picked a selection of elements that I wanted to get proportions of and then I picked the points I wanted to know about specifically. From the element maps and the back scatter image I had taken previously I knew that I apparently had several minerals (I had trudged through four large tomes of mineralogy and lunar/planetary stuff to find out what sort of things I might have lurking in the sample. I had then taken the element maps and compared them - drawn faint scetches of them and then working out what elements I had in conjection where drew on mineral areas with coloured pens onto a printout of the backscatter image. (He told me this was actually an x-ray map just not element specific so I need to check whats what with him I think).

They seemed quiet impressed that I had done this but it seemed like the only way to make things clear to me personally. I was becoming frustrated that I couldn't work out the actual proportions and therefore the exact minerals from the elelment maps and that I could only narrow things down. Fortunatly this is what today was actually about so I worked out how many samples I wanted and were to take the measurements - unfortunatly becuase there is a bad polish on the sample I had to be careful and was highly restricted in where I could take measurements.

But I selected 101 points each point was going to take about 9 minutes to analyse but I specifically went in early to get it all going and as it turned out had plenty of time.

I had also narrowed down the minerals really far more accuratly that I thought I had and I had worked out stuff about my 'dirty' quartz that that does seem to be correct which is very cool and makes me feel like I might just have a chance of doing this.

The only thing is I found myself baulkin at the interface of data and computers - there are situations that I just see no reason not to have a computer automate and I think they should be relatively easy to implement and yet there is nothing! This keeps happening every where I turn in geology and earth sciences there is just huge gaps that computers could feel reducing monkey work and increasing the amount of research that can be analysis in depth!

Other issues that I have had is finding information barred to me - this is painful when I would happily pay say £10 for an e-book of the phase diagrams I needed or even just the chapters I needed - then and there I may even have gone up to £20 but it is only avalible as a book and at around $300 which sucks big time.

Can anyone tell me what the restrictions would be on me finding data in papers and ploting my own graphs/diagrams and then putting them on the internet for free so that people like me don't get stuck like this? I just needed a guid to see if I was on the right path. The question of science on the net has been interesting me alot in the past year and I wonder lots about hwo things are going - I like sharing info and I think it helps move projects and science as a whole on but there are those who tell me that I sholdn't talk about my projects and ideas incase they are published by other first.

Also there is the question of funding and where the money is coming from to do the research - I find myself pondering over the wole peer review system and how a nice fast version could apply to articles on line - making the turn around of science much faster without loosing the reliablity.

It is a thorny problem and I feel slightly swamped in it.

Oh well I'm sure I'll sort it all out eventually 🙂

The only scary thing about todays stuff was that if I want to go out of the lab I have to remember to press a button that puts an alunium or copper block infront of my electron beam so that it doesn't burn a whole in the sample - this made me quiet nervous!

Join me blogging for Ada Lovelace Day (by sarah)

Tuesday the 24th of March is Ada Lovelace Day - this is a day of blogging about women in Technology, ones who have inspired you or that you admire.

Ada Lovelace is known as the first computer programmer in history though she didn't actually have a computer to run them on. She made them all from the description of Babbage's machine which he never finished.

She also saw far more potential in the machine than even he did and was well ahead of her time. Now I am posting this becuase a) we are obviously going to be doing write ups on this for this blog, my astronomy blog and web-empires blog - I'm not sure I can find relevent technology craft/art and cooking cross overs in time for the Salaric blogs but I will try. b) I'm hoping that alot of you lovely people will take up this challenge - from a personal point of veiw it would be nice to see the science side of technology and not just computing to be recognised - so geologists, chemists and astrophysists pull your fingers out, oh and anyone else who wants to off course! c) this will raise the profile of women in technology so that hopefully young women choosing careers paths and those debating weather to rejoin after a the whole 'career break'/having baby/looking after sick people can see that they are not alone and that both currently and in the past there female role models without whom medical advancements and the like may never have been made. (Or at least taken twice as long as there is an idea that you just need a saturation point for idea nucleation sort of thing).

I contacted the organiser and asked what they ment by technology and they said it is perpusfully broad and would include science etc... 🙂

There is a pledge page where you can add yourself to the list of people who will blog. You can follow it on twitter and it has a face book presance. There is also a mailing list and to find tweets about it on twitter its designation is #ALD09.

I am probably far to excited about this and I think you will all be suprised by the one we have on here 🙂

So you lot lets get writing 🙂

analysing the moon rock (by sarah)

Friday saw me once again wending my weary way to London.

This time I was going in to carbon coat my lunar meteorite thin section and put it in the machine to make X-ray maps of specific elements. I felt very nervous as I hadnt done anywhere near the amount of reading I had ment to do for it what with boundary disbutes and work stuff etc...

And I had been highly confusing myself by trying to learn lunar mineralogy from scratch - complete with minerals I have never heared off! I had started making a list of elements mentioned in association with lunar minerallogy and then side tracked myself - turns out if I had completed this it would have been a very good start - oh well.

I was a bit sad when I arrived that the sample was already in being carbon coated - I assume the machine works by some sort of spluttering of carbon. You coat the sample to help get a clearer image by stopping alot of the interference(I think). This means I only got a pic of it carbon coated thin section and my hands were shaking so its not a very good picture anyway but this is a piece of the moon that fell to Earth in a meteorite that Landed in Africa.

The Carbon coating machine:

My piece of carbon coated moon rock!

This means I also have to be weary of terrestrial contamination when analysing it.

I took photos of the machine and bits around it!

What I have done for the mini project is just selected one breccia clast/grain out of this thin section from a few cubic cm's of lunar meteorite to ananlyse. This really is looking at the fine detail - I always have to remember that it is part of a system, part of a big over all picture, the small makes up the big and the big affects the small.

We chose which elements to map for, then defined the mapping area which was just slightly bigger than the clast. An important fact is that no matter how good the polish on the surfacce of the section it is not completely flat so to get golod results you have to sort of take the four corners and average them into a focus plan. At least this is what I understood to be happening.

Anyway I selected with some help the elements that I wanted maps for and the grand total time was 56 hours running time for the machine - wowowow. Of course this is why I was in there on a Friday afternoon so that I could have the machine run over the weekend - I clicked the button to start it and away it went.

I then proceeded to make a fool out of my self by saying - its obviously regolith isnt it - erm... we dont know came the reply. I am also very intreged by the clast I have chosen to analyse - it looks like two main minerals interlocked in some sort of intergrowth way - each with its own specific selection of other mineral inclusions.

I am a bit worried that I just dont remember enough mineralogy to do this project justice :/

Still I think I may have some idea of whats going on but suffered that thing of not wanting to say anything incase I was wrong and they thought I was stupid and wasting their time and effort. I now need to go and work out the correct scientific termonolgy instead of inventing my own - again.

Still I got to take pics of the sample being mounted in the machine including the adding of the highly conductive copper sticky tap that also keeps it in place!

There was one interesting point - the machine appears to do a continues scan but it doesnt it stops every .... and 'dwells' for.... this leads me onto something else I have been pondering recently - how different are analogue and didigital - you came make one appear as another depending on resolution etc... but this needs a me to do a bit more thinking and maybe write a few books on the nature of existance I feel!

Once I have worked out the mineral phases in the sample - which I will do from these elemental maps I will be putting it in the microprob for furthure analysis.

I think that for my oral presingtation and poster I will therefore need to focus on what we know of the moon from meteorites rather than just what we know about the moon.

I am getting very excited about all this - its the thought of being able to tie in the mineralogy of crystals grains within a clast with a brecciated meteorite to lunar and even solar and possible even universe formation processes!

Happyness is once again rock shaped. Though I am hoping the element doesn't blow over the week end - it was a new one this week so hopefully it will last!
