Maths and Physics

I had this lovely piece of written feedback in an email from a student yesterday. I … think your emphasis on the physics rather than the math that describes it … is really good, my problem solving approach has changed from wondering what equations I have at my disposal to what’s actually going on.     What […]

Dealing with random things

In physics, just like elsewhere in life, there can be more than one way to tackle a problem. An example I’ve been thinking about recently is in the computer modelling of random processes (which is essentially what my research is about). Rather than talk about neurons and what causes them to fire or not-to-fire, I’ll draw […]

2.5 or 2.2 percent?

So, Goods and Services Tax has now jumped from 12.5% to 15%, and with it comes all sorts of confusion. If you ask the question ‘how much have things increased?’ you can get a variety of answers? So, an example.  Take an item that used to be priced at $11.25.  OK, so we no longer […]

Quantum finance

I would say I generally think captialism is a good idea, but after my experience on Tuesday night I am beginning to wonder. Does any of this sound familar? Ten years ago I bought a policy (call it policy 1) with financial organisation A. It was a ten-year one – paying out just a few days […]

Computer models

For the last couple of days, I’ve been engaged with a student of mine on a computer-modelling problem. Specifically, it’s an electromagnetic problem, working out how the electric field behaves between an array of electrodes. It’s a useful thing to do, because the outputs of the model will help guide future experimental work, and help […]

Trouble brewing

Following Germany’s destruction of England and now Argentina, I’m getting distinctly worried that Professor Tolan’s probability theory  is about to be proved correct. It will be a sad day for mathematics if he starts saying ‘told you so…’

Does the future affect the present?

Well, my comment on Naked Short Selling has certainly sparked a bit of discussion (for readers on sci.waikato.ac.nz/physicsstop you’ll need to look at the sciblogs hosting of the blog, http://sciblogs.co.nz/physics-stop/ ).  There’s the reasonable question asked as to whether letting people trade in things they don’t yet possess (basically anticipating the future – letting the future, […]

Going Naked

I’ve been reading about Naked Short Selling, following Germany’s decision this week to ban it. What the financial world gets up to is rather interesting, to say the least.  For those who don’t wish to read about it themselves, my summary is this:  Short-selling is where you borrow something, then sell it, buy it back […]
