I had a Dream

Actually I've been having lots of very vivid dreams which doesn't bode well for sugar levels but I haven't got the results of the Glucose Tests back yet - by this time with Jean's pregnancy I had gestational diabetes. But then I often have vivid dreams - many of them are what is termed lucid and I have some sort of control on them. Part of this is the fact that when pain levels are high I don't actually go to sleep properly so I am in a sort of resting trance. They have benifits but it makes it harder for you body to repair itself from injuries - this isn't mumbo jumbo this was out of the Drs mouth at the pain clinic when they attempted to medicate my sleep when we lived back in Essex.

Anyway I thought I really needed to share lasts nights dream. It starts with me trying to get to a PhD interview at Reading University - the PhD is about modeling other solar systems and exo planets etc... I have no idea if Reading does this sort of thing but it was Reading in the dream - the only issue was Alaric was running late so instead of having a nice sedate drive to the interview we had to high jack a state of the art plane from the local army base type place.

As we took off I noticed the tail wasn't actually attached to the plane but the whole thing was segments held together a bit like a kite - the tail itself looked remarkably like a cray fishes or something lobstery only in shiny metal.

We get to the university and I am late - I haven't read the notes on what the things is actually about but they agree to see me anyway as there is only one other candidate - a UG astrophysics girl. I then proceed to think on the spot and tell them that they need to reassess everything. I tell them that what they need in a lovely large database with a nice archive mode - this is sort of a giant wiki with the ability to pull meta structures from the data such as phase diagrams. You see I don't just want to make a database of the planets and the physics but why not add all of mineralogy and astronomy?

Why not had layers where people can choose the data to run their simulations and the like? In the dream I'm in a pale yellow room with aging equipment and they are like - we don't have the money to pay the programmers and our stuff never quiet works.

Of course it doesn't I crow - your not programmers and you just use which ever language you happen to have picked up. Then I tell them not to worry - I'll make the database - I'll make the initial system and we can have people adding their own stuff!

It would be massive and everyone would argue about things added which is were the archive system would come in - they could just take an previous theory ect... With this we could easily extrapolate the composition of planets around other stars. It could have the ability to swap between notations so no more issues over what a Chemist calls a metal compared to a Geologist compared to a Astrophysist etc...

I have to say at this point there was decent in the interviewers - there is of course a problem of who the data belongs too and would we have to pay and keep it secret - that would hamstring the project - it would kill alot of their grants dead etc... alter the peer review system. Subjects that I have touched on before whilst awake!

But then I point out that it would have commercial applications and launched into a whole thing about the gaming industry being a growth sector and how you could build games engines on this thing! (again this is something we are sort of doing anyway in the real world but not with real physics).

I point out that scifi authors and the like would love to get their mitts on such a database too - for it would make world building a lot simpler and you could make smaller custom ones.

They were still like but we need someone to make all this and we just wanted a data monkey to enter numbers into spreed sheets. I laugh and say I can build it for them (I can't but I'm planning on using an advance version of Alaric's Ugarit.).

Anyway it ended with me negotiating to mainly work from home and stuff.

Part of me is now going - this needs to become real! We need to have this database - an extention on an idea I had a few years ago! And Alaric was like that is exactly the sort of thing the archive mode of Ugarit would be good for. The arogance of me in the dream was a suprise though. Besides last time I had a PhD interview I told the person their project was recording the wrong things - which didn't go down too well :/ And this dream is just that rite large - plus there is no way I am going to be doing anything academic for a while either - but it was a cool dream non the less!

Benign Polyp Gone

Alaric's fleshy lump is gone from his scalp - they used elctro-quatrazitiation which will leave a small scar but hey it's in his hair and even if he lost all his hair it wouldn't really show. there is a black, burn/scab thing there at the moment and there was a line of scabby blood from it yesterday evening which scared poor Jeany :/

But it is smaller than the lump was! It was apparently a benign polyp which my family thinks is haliourous as we call each other polyp (as in colonial organisms re: biology and not swellings and lesions re: medical).

I'm applying eye cream of all things too it as it is the best stuff to stop infection of which there is a bit of a risk as they couldn't put a dressing on it - I assume this is not large though or they'd have shaved him or asked us to shave him again.

It is a big relief I think I was more worried about it than him.

Lump Removal

Alaric is going in for his lump removal today - it is only minor surgery so shouldn't be too bad. He is also on the more fierce fungal killing medicine which is making him a little under the weather - still I think he'll feel much better once all of this is over!

Plus strange fleshy lumps on your scalp need to go!

Old Papers (and maths!)

This weekend, I've been going through old papers and dealing with them. This involves sorting them into three categories:

1. To be shredded and turned into logs with our log maker
2. To be filed in the cabinet (with many subcategories corresponding to the files therein), and sorted by date where applicable
3. Demanding some action (which, for now, means putting them into my in-tray, rather than disrupting the activity in progress)

The magnitude and importance of this task is not to be underestimated - when we moved here I had a new baby, a very sick wife, and two jobs to deal with; unpacking and properly setting up my office never really happened, as opposed to setting up a desk and digging through boxes to find the things I needed to get started. So my once-pristine filing system was never quite established, and my "to file" tray grew fat with paperwork I needed to put somewhere. There was slow progress, of course; but then two years later the house flooded, so we had to rush a lot of furniture and stuff from downstairs up into the office, then pack a lot of stuff up and send it into storage while the house was repaired... and we weren't living in the house for nearly a full year, so more often than not I was working on my laptop from wherever I could get an Internet connection. Once again, my paperwork was in disarray.

But, three years on, we're finally catching up. I've gone through my filing cabinet and re-filed the mish-mash therein, then gone through my to-file tray and the various piles of papers dotted around the place, and dealt with them all. "To shred" has been by far the biggest category; as I write, Sarah is sitting feeding sheet after sheet into the shredder. And I've found a bunch of interestings that need further action.

For one of them in particular, the action is to write it up. Many years ago, I bought and read a book on statistics in order to refresh my memory, as I was working on a system for analysing the actions of large numbers of people. Now, I didn't enjoy statistics much when I was doing A-level maths, and reading the book reminded me why: I find the random-variable notation unnecessarily vague and confusing, and the various other notations used in statistics seem inconsistent to me.

I recall reading this book on a long bus journey (the bus from Tottenham Court Road to Gallows Corner in Romford, to be precise), and deciding to take matters into my own hand, and designing m own notation for statistics based on set theory. I like set theory and find it sensible and logical, so this was an obvious choice. I wrote my notation down on a sheet of paper, tucked it into the book, and took it home.

Many years later, I found the sheet of paper inside the book, and put it in my TODO pile, as I needed to take a second look at it and do something with it. This never happened. Until now.

So without further ado, here's the content of the sheet. It still needs more thinking about, but if I write it up into the computer now, this is more likely to happen than waiting for me to encounter this bit of paper again.

Let L be a multiset of real numbers.

• SUM(L) = sum of x, where x is an element of L.
• |L| = the number of elements in L.
• L(n) where 1 <= n <= |L| = nth largest element of L
• MIN(L) = L(1)
• MAX(L) = L(|L|)
• MEDIAN(L) = L(|L| / 2) if |L| is odd, (L(floor(|L| / 2)) + L(ceil(|L| / 2)))/2 otherwise
• SUM^2(L) = sum of x^2, where x is an element of L
• VAR(L) = SUM^2(L) - (SUM(L))^2 etc.
• L ~ D iff L is distributed as per D (D is a distribution as per normal stats notation)
• SRn(L) is a multiset of all possible sets of n random samples from L with replacement
• SWn(L) is a multiset of all possible sets of n random samples from L without replacement

Let L be a multiset of records (named tuples) of real numbers (a,b,c,...)

• La is a multiset of just the as
• Lab is a multiset of the products, a*b
• sigma(L) f(a,b,c) is the sum of f(a,b,c) across all the elements in L
• pi(L) f(a,b,c) is the product
• L ~ (D1, D2, ...) iff. La ~ D1 and Lb ~ D2 and so on
• cov(a,b)(L) = sigma(L) ab - M(La)*M(Lb)

...and there it ends!

Convince Alaric to let the Drs Put him under the Chop

Alaric has a... well nipple on the back of his head, the size of which only became apparent when we chopped off all his hair to try and deal with a dandruff problem. The dandruff problem turned out to be interesting as well but more on that later!

This lump on the back of his head has a distinctive look and I found a couple of smaller ones on him (one of which I had accidently mangled with a razor ). The Dr says it's a variation on a wart but isn't that contagous but that it should be removed - doesn't have to be but should be. It will really need a scalpel taken to it as it is too large and fleshy to be frozen off and it simple wouldn't get it all.

Any way - due to the horror on Alaric's face the DR said he could think about it - I think it should be removed - help me convince him
