not such a good day at the office

Visible to anyone in the world
Edited by Neil Anderson, Friday, 14 Jun 2013, 20:50

Today was the numbers exam.

I arrived to find a gratifying number of mates smoking in the car-park. So things started well, once I opened my paper things changed; for some reason my mind turned to mush.

There was a question along the lines of: prove gcd(4n + 3, 4n - 1) = 1. I couldn't see a way to do this. This is so basic that I'm embarrassed.

[Let d = gcd(4n + 3, 4n - 1), then d divides 
4n + 3 - (4n - 1) = 4 and as both 4n + 3 
and 4n - 1 are odd d = 1]

This is something that I've done hundreds of times and should be second nature, why did I freeze?

The entire exam was littered with moments like that. Under pressure it seems that I crumble intellectually.

Am I down? Not really, I will get enough marks to either get a free resit or I will pass; either is good:

  • I pass, then it's over
  • I resit, the groups showed me that it is possible to get a better mark than you might originally have gotten

I've always been a game-player, and the thought occurs that aiming for a re-sit may be a viable option. Is it indeed the best option?

Anyhoo, for me, for now, the maths is over. Now all I have left is the the computers.

doing

Visible to anyone in the world

Diophantines. Tonight.

Maths has been getting to be a bit of a stretch for me for a while now and M381 will maybe, probably, be my last maths course.

[Although I feel a bit contractually bound to doing M209 because of my mate Chris. Actually I will have to have a look at the dark side sometime, and feeling that I am doing it for Chris will help.]

This has been hard for me, this being the OU stuff. A lot of it has come easy—computer stuff, a lot of it has been challenging—early maths stuff, lately maths has been a batcrap crazy madness that makes you feel that you are climbing down a wall with weights tied onto your head; weights that float.

But there are times; like tonight. Tonight when I began to see a structure in numbers that I wouldn't have see without the work I've put in. I'm still scrabbling at the harling, of the wall, of the building, that is part of, the maths complex.

Today I saw something that Fermat saw, and I saw it without a prompt. Doesn't matter that I was a horse lead to drink.

I saw it for myself. That matters.

tma away...

Visible to anyone in the world
Edited by Neil Anderson, Thursday, 28 Mar 2013, 19:36

For the computer course, one unit completed for the maths course and one TMA question grokked for the maths course.

Plan for the weekend [a long one]? Two maths units read, three TMA questions grokked. Plan for tonight? Fire up Dia and create some sequence diagrams for the solitaire thingee! >wink

Sometimes one must allow yourself some fun...

... and some Muse.

I'd planned that my m381 moans would be off-set by a, much more chipper, post about m256, where I'm having such fun. A balance if you will. However, you will have to put up with my regular moaning self.

tired

Visible to anyone in the world

Mortal tired.

I have a maths TMA to get away tomorrow, still two and one half questions away from completion. I have a day off but my wife and I fancy a walk in the woods.

Am I sick of maths? I don't know; TMA hell-time isn't a proper time to be thinking about anything but there's someone inside me saying, "you've proved that you can, give it up now". I lack the will to argue with him.

I understand but I don't grokk. Everything is so hard. Recently I started a computer course and it was, "wow! this stuff is easy". Have I lost the plot?

I need that walk in the woods more than the marks that I'll get. There's something wrong with my head that only open air and nature will cure.

a bad thing happened...

Visible to anyone in the world
Edited by Neil Anderson, Wednesday, 16 Jan 2013, 21:16

But for once, it wasn't a total disaster, for me, depending on your hierarchy of bad things and point of view.

<segue />

Let me just state, for those peeps who are just starting their OU trek something about me, I moan and bitterly complain about my OU trek, but it has been the best thing that's ever happened to me.

So when I come across all negative don't look at it as anything else than that I'm a whiney arse.

Have fun folks, this is really the best place to be.

Of limited interest but in the grand traditions of this site I offer some muzac. Remember that we are only a link in the generations of fighters for right.

Should we all link to music?

i caved

Visible to anyone in the world

I read a number theory unit in the bath today, and I suspect that it will be bedtime reading tonight.

I don't suppose that this is too dire—it is maths.

For now it's back to the fractals...

numbers

Visible to anyone in the world

A man finally arrived with my brown-box of numbers books. I had planned to spend some quality time with topology today. That plan went out of the window.

Today I've spent my time sitting on the floor reading my numbers books [it's a holiday in Edinburgh today]. I'm going to like this course: universal register machines, primative recursive functions, prime numbers, computability ... this is geek heaven!

I will have to spend much time on topology, groups and the hated geometry over the next few weeks but now I have a pudding to look forward to.

This is what I signed up for, sheer logical madness and I have a computer course starting in February too.

I'm neo again.

Plans gang aglay.

The parcel people say, "Consignee Cannot Be Reached".

I get stung on the lug by a wasp.

Started the new course blog though.

books

Visible to anyone in the world

Having been so busy cocking up unfinished TMAs over the past couple of weeks I hadn't really though about my next set of books. They are now, "out for delivery".

As many of us know, this is not the same as they are going to delivered any time soon. But it does mean that I need to start another blog <sigh />.

I should probably do that now.

I can't say that I'm in my usual state of excitement but I know that will change when the books eventually do arrive.

Number theory eh? Wonder what's that about?
