Emacs and Jupyter

Today I discovered the sheer awesomeness that is Emacs with EIN. This lets my Emacs environment to to Jupyter Notebooks. Through it, I have the power of Emacs Python completion and editing while writing iPython functions. It works really well! I can display matplotlib graphs inline in my Emacs buffer. There is even symbolic computation via the sympy package! Bliss!

Using Mathematical Models to Reward Behaviours

Today I was thinking about creating a mathematical model to represent my own personal “Klout” score. Instead of providing a measure of social influence, it would actually be a day-to-day score of how social I had been. Lately I have been quite reclusive. Other than Helen, I haven’t had much contact with people. I have also been a lurker on social media, such as Twitter and Facebook. In order to encourage more social interaction, my score would keep track of how many interactions I have. Whether the people I interact with are new people to me, or whether they are friends. If I construct the model properly and use it on a daily basis with an aim to improving my score, it should get me out of this reclusive rut I am currently in.

Effective Study

I have been studying continuously for many years now. I am still refining my studying technique though. One of the things that I am being forced to do with the maths I am doing at the moment, is to read and re-read the course materials over and over again. My workflow at the moment is:

  1. Skim the chapter. Scan the headings and sub-headings and try to build up the outline in my head.
  2. Skim through the problems within the chapter.
  3. Speed read the chapter. Get more of an idea of what is going on.
  4. Read through the problems and the answers.
  5. Read the chapter more thoroughly. Try and get a good understanding.
  6. Work through the problems.
  7. Repeat 5 and 6 until either clarity or the exam arrives!

Mnemonics for Maths

I have been studying maths for quite a few years now, but I still find it a struggle to remember various formulas/equations, especially when starting a new topic. I’ve been thinking about developing my own mnemonic system for math symbols to help me memorize equations easily.

I would need to relate various mathematical operators to something else that is easy to visualize. The bracketing of expressions is problematic, you would need to have a way of visualizing a collection of things that the operator acts on.

I think that having a mnemonic system for maths would help internalize the ideas and models within a domain. It’s obviously still a work in progress!
