SM358 The Quantum World 25% in…

When I was looking at the level three maths modules for my Open University degree, one of the ones that really drew my eye was SM358, the quantum world.  I decided to only do a single module this year as I’d committed to a lot of speaking engagements in October and, in addition to my day job, I’ve been spending time on another project that I’m really excited about for the start of 2019.  From past experience, if you fall behind on OU modules at the beginning, it can be very hard to catch up.  This was really noticeable with the complex analysis and stochastic dynamics modules I started in 2017.  Rather than taking on too much, I decided on just one level 3 module.  Given my progress so far I’m only about a week behind and I’m pretty happy with that.

2 out of 3 ain’t bad: back to back TMAs

MS327 progress – not where it needs to be to do well on TMAs

It’s been a crazy month.  From the lead up to the product launch at work to know it seems like I’ve been doing nothing but back to back assignments for my Open University maths degree.  So much so in fact that I’ve not had time to study, but only focus on the assignments themselves.  It all started back with the second TMA for M337 (Complex analysis), which was a rush job and I got a much lower score on that than I would have liked.

I then had two weeks until a computer marked assignment for MS327 and was going into this without having looked at any of the material in the book.  As usual, I spent my commute trying to get through it, but barely made it a quarter of the way through  before I realised I’d have to start working through the questions for the assignment.  Computer marked assignments are very different from the tutor marked ones.  You either select an answer from a choice of 4-6 potential results1 or by typing a numerical result.  Therefore your answers are either correct or incorrect.  There are no marks for method.

If you find yourself in this position, my best advice is always to do the unit quizzes.  These are usually in a similar format and will get your brain in the right place for the assignment itself.  In combination with the handbook and text books you should be able to follow how to get the answers from the questions, although please make time to go back and fill in the gaps as soon as you can.

Noise levels at the local soft play centre. Earplugs don’t really help – it’s so high pitched you feel it through your teeth more than your ears 😉

With the iCMA out of the way, I then had a week for the third TMA of MS327. Fortunately on the same topics as the iCMA, but much more involved questions.  This was a lot trickier to pick up.  With the usual standing room only on the commute, I’ve had to spend a lot of evenings trying to do this around family time and study in the excessive noise of soft-play centres… not a great environment for thought!

 

So I’ve just submitted the MS327 TMA online and I’m pretty happy with it.  Now I have two weeks to get the M337 TMA3 done and I’m a little more nervous about that.  There isn’t time to go through the study materials and answer the questions, so I’ve given myself a week to get as far as I can and then I’ll dive into the TMA and see how far I can get…

On the plus side, the OU offers substitution on your assignments, so it’s okay to have a bad one and you’ll be allocated a score that’s the average of the other three.  So I can still pull up my average for M337, as long as I do well on this TMA.

This level of progress isn’t looking good at the moment…

I’m really hoping that I can get time to get these to 100% before the exams in June!

Can I do calculus in my sleep?

Breaking discipline with my Open University studies is never a good thing.  Once you’re behind, it’s so difficult to catch up, especially with a full time job and a young child.  It’s been a crazy few weeks at work too, we’ve had a major launch event and lots of projects with looming deadlines.

It was in the days leading up to this launch that I had a TMA due for one of my level 3 OU modules, M337 Complex Analysis.

With all the other deadlines I’d only done half of the study necessary for the TMA. This is never a comfortable position. I got away with it at level 1 and mostly got away with it at level 2 but you really can’t do this at level 3. Especially when the focus is calculus of complex functions. I made a start in good time, but without the time to really get my head into the topics, it was always going to be an uphill struggle to make the intuitive leaps necessary at this level to determine the correct method.

Not a particularly healthy sleep profile…

In the days leading up to that TMA my sleep profile was pretty awful.  I can’t remember what caused it, but I had so many nights in a row where I got very little quality rest.  This isn’t great.  It impairs judgement at the best of times.   I could have asked for an extension in good time, but that would just compound the problem with the MS327 assignments in a few weeks1.

this is what maths looks like when you’re slowly losing consciousness!

When you’re sleepy, it’s easy for “i” to look like “1” and “z” to look like “2” particularly in equations where there are other terms with these numbers.  One of those days I found myself working on problems from the wrong module (MS327) and just looking at my notes it’s pretty obvious that I nodded off in the middle of writing these2.  Maybe it isn’t that obvious, but trust me that this level of spider scrawl is not representative of the handwritten work I normally submit!

The results of my assignment are back and it turns out I can’t do calculus in my sleep, let alone path integrals of complex functions.  I really do need to up my game and attribute more time to this degree3.

On a side note, I’m really pleased that my presentation at the launch event was recorded – I was a little light-headed after giving blood on top of poor sleep. I presented for 5 minutes and couldn’t remember a thing I said immediately afterwards.  I got some great feedback, so there’s definitely a learning there for being relaxed, not overthinking what you’re saying and also speaking about what you know!  I’ve only heard the audio so far, but will post the video when I have it.

 

 

M337: Group theory becomes relevant

My M337 books are starting to look a little dog-eared after a few weeks of commuting!

One of the things I’ve enjoyed least about my OU Maths journey so far has been group theory.  I ploughed through whole swathes of M208 applying the techniques and not really seeing the relevance1  I found group theory and the proofs related to it tedious.  Mainly because I was proving something that was “obvious”.  However, I’ve always had a healthy acceptance of partial learnings – knowing that if I was being taught a technique then there was a reason for it. Two years later and that reason finally hit me. Continue reading M337: Group theory becomes relevant

OU level 3: Complex numbers and stochastic dynamics

Books for this year: Complex numbers and stochastic dynamics

I gave myself a birthday present again this year, by registering for another 60 points worth of Open University maths modules. I’d put it off for quite a while as I couldn’t decide which level three modules I wanted to do most and also in which order. The only fixed option was “The quantum word” which was only available once I’d completed1 60 points worth. This left me with a choice of 3 modules from 4 other interesting options. Sadly, I discovered (thanks to a comment) that the pure maths module I intended to do was a 60 point module, meaning I either had to lose that from my choice or two of the modules I was really wanting to do. In the end, pure mathematics lost out and I’m committed to four 30 point modules. Continue reading OU level 3: Complex numbers and stochastic dynamics

OU Maths – decisions on level 3

This week was results week for the Open University. Many of us who had been checking the website weekly since the exam1 finally got the link through to our overall module scores. If, like me, you were waiting for a result then I hope you got what you needed2. MST210 marks the end of level 2 of the B.Sc. Mathematics and I now have some choices on level 3.

Professional body for data science? Yes Please

Statistically significant
My new prized badge from the RSS

This week I was delighted to be at the Royal Statistical Society as a business representative for the launch of their Data Science Section. At over 160 years old, the RSS is one of the more established professional bodies and I like that it is questioning and making a difference as the application of their industry changes and when faced with an increasing challenge of abuse of statistical methods. I wish the general public had a greater understanding of statistics so they wouldn’t be so easily swayed by the media with a simple graph “proving” a point.

MST210 – Exam and modelling exercise reflections

Revision day essentials – revising in 1 day is not recommended

This week was the exam for my level 2 OU module MST210 on methods, models and modelling.  This was a compulsory module, but had it not been I would have never chosen it.  The module has been mostly applied maths, which has been really interesting, but what’s been a problem for me has been the mandatory team work modelling exercise, which makes up 16% of the continuous assessment.  So much so, that I lost motivation to do the final TMA or revise for the exam as much as I wanted to.  I thought it would be worth a short reflection on why I disliked this aspect so much (especially as it led to a repeat of last year when it came to revision…).

MST210 – Lack of routine has consequences

After the lack of focus I’d had studying for M208, I was adamant that with MST210 I’d get into a routine and stay on top of the work regardless of what else life through at me.  This worked pretty well in October and November.  I did the work during my commutes, approximately 3-4 hours a day, even if I had to sit on the floor of a train carriage or find a dusty corner of Paddington while waiting for a delayed train.  All was going well.  At the end of November I began the process of changing jobs and, because of the nature of my work, was put on garden leave for three months.  Suddenly I wasn’t confined on trains for about one seventh of every weekday.  This is where my whole routine broke down. Continue reading MST210 – Lack of routine has consequences

Diagrams with LaTeX – easier than you might think

Diagrams like this are easy to do in LaTeX

I’ve written before about the power of literate programming, using \LaTeX to create reports when code runs.  It’s fairly simple to combine this with the graphical drawing packages to create impressive graphs and figures on the fly.  A lot of academics I’ve spoken to have shied away from using \LaTeX for drawing, despite being very proficient with the textual layout.  Similarly, a lot of students on the OU Mathematics degree write up all of their assignments in \LaTeX but drop in hand drawn graphs and diagrams.  Just like anything else in \LaTeX, once you get your head around how it works, it’s actually not that difficult to create very complex structures.
