Just when I thought I’d figured it all out, comes shit like this:
‘They are the sort of equations that arise when you try to study something that evolves in time but also depends on space.
‘For example, like the wind in a wind tunnel you want to model the flow of air then that of course depends on time because it changes over time but it also depends on space – the velocity of the air is different at different points in the wind tunnel.
‘So if you have a system like this which furthermore evolves under the influence of randomness.
‘So if you have randomness that enters the game then that’s described by stochastic partial differential equation.’
I used to work with people like this when designing predictive algorithms, and I would place bets with myself as to how long (measured in seconds) it would take before I lost track of the conversation completely and the speech became unintelligible. Usually, it was about twenty seconds.
It gets worse. The reason I used “20 seconds” in the above sentence is because I actually kept count, over the year’s worth of discussions and meetings, of the times. Then I created a distribution chart — bell-shaped, of course, with the most common incidence around 20.
Yeah, I was a fucking geek, too. Just a much more limited one.
By the way, if you read the article — and you should — there’s a glaring (but non-mathematical) error. Call it the Obama Fallacy, and see if you can spot it.
