TMA2 back in, TMA3 about to go out

Dropped a mark somewhere on TMA2. All good.

TMA3 has been a bit trying.

Some of the NT caught me out. Can’t say more than that as the assignment deadline is still a few weeks off. However, staring at something and realising my interpretation of it was, well, silly, eventually put that right.

The ML was very enjoyable. Book 4 was a cracker – best read of 2014.
Book 5 was also a cracker but is probably the first book in the course where I had to do pretty much every exercise and additional exercise to get the hang of what was going on.

The ML TMA questions seemed quite doable – couple of potential pitfalls as ever.
The only bit that really caught me (I think – who knows – I might have written complete rubbish for the rest of it) was the final part of the final question – a somewhat odd-looking thing to prove, I thought.

Anyway, that last part took quite a while. There are many ways to go about these questions and it wasn’t until I concluded I was very stuck and needed to rip up what I had been doing that fresh inspiration dawned and, wayhay, it was proved about two minutes later.

I poked my solution with the maths stick, checking it against all known rules and interpretations, pitfalls, etc, I could find in the notes and it appears to work. A very well-designed question to ensure you understood what was in the notes, I thought.

Tomorrow night off, then start on the reading for TMA4.

I want TMA4 away by the end of March, to give me 10 or 11 weeks of solid revision for the exam as, to my horror, having looked at the skimpy handbook, I discovered that none of the tricky stuff in book 5 is even summarised or mentioned in it.

In fact, the handbook just says: “The handbook contains no results for this unit.”

M381 continued

Or, should I say, continues..

I have pretty much finished the logic books for the next assignment – TMA questions over the next couple of days.

Then, it’s time for the number theory books – some good stuff in them, from the looks of it.

Something strange has been happening – causation/correlation, be gone – I’ve been taking low doses of fish oil and krill oil for a few weeks now, and my memory has definitely improved.
So much so, that a poem I wrote aged 12 came back to me today – word for word – decades later.

I’ve written it down. 🙂

Placebo, maybe, but it’s working.
