New blog

I'm no stranger to blogging. There was a time when I wrote almost daily on two blogs (in Dutch): on "De conceptuele ingenieur" (no longer online) I wrote about philosophy and science, and on "QED" (archived at I wrote about mathematics and computers. But more than ten years ago I stopped blogging, because I lacked the time.

For a couple of years I have been thinking I should start over. Now's the time. But this time not with a specific theme or a split personality. On this blog I will write about everything that interests me.

That's it for now. You'll see what comes next.
