<h3>not finished</h3>

<p>I didn&rsquo;t pass the exam, so months later, I&rsquo;m back doing the groups again. Which might not be too bad a thing&mdash;I may be learning something. Something about myself <em>and</em> maths.</p>

<p>For the last few weeks I&rsquo;ve been dipping my mental-toes into groups again, I&rsquo;ve even done a wee bit of the geometry, hateful as it is, so that I can garner any low-hanging marks that might be gotten in the exam.</p>

<p>I had something of an epithany yesterday&mdash;I could read the handbook. Funny that I hadn&rsquo;t thought of that before; perhaps there are other things that I should have done, like watch the videos, listen to the tapes or peruse the books that lie unregaded upon the bedroom floor? Maybe I should talk to my tutor? Go to the tutorials?</p>

<p>It, this epithany about the handbook, was something of an eye-opener, all those things that didn&rsquo;t quite gel suddenly started to make [a bit-of] sense. For example: I must have known that the kernal of a homomorphism was a normal sub-group but let&rsquo;s just say that it wasn&rsquo;t at the forefront of my mind.</p>

<p>Once I knew this was a fact known to others it took me about five minutes to prove it from the morphism property&hellip;</p>

<p>&hellip;I wonder what else I know that I don&rsquo;t properly remember?</p>

<p>Somewhere I wrote about my <a href="http://neilanderson.freehostia.com/thoughts/degree/m338_336/#blues">group theory blues</a> the thoughts have&rsquo;t changed it is just that I might have. The dub theory of the blues? Same backing number, wrong singer.</p>

Good lucksmile

ps every normal subgroup is the kernel of some homomorphism. I don't know how they present it.
