“Post hoc ergo propter hoc” could be translated to “after this, therefore because of this”. This is a logical fallacy about following false patterns. This is not a site about that, but instead about (hopefully) true patterns – hence the name proper hoc, which loosely could be translated to “this is correct”.
The site is divided in a business part (about my firm) and pleasure part – and the pleasure is the maths, the physics, the electronics and so on that I do for a hobby. Wait a minute – that is what I do in my firm too, so the pleasure part may be seen as an advertisement for my firm.
Anyhow – please click on the menu, select what suit you, and enjoy.
