An empirical evidence of Fubini’s law

Last week I wrote about the mysterious Mr Fubini, who created a law that describes the adoption of new technology. A faithful reader of my blog, however, remarked that it’s easy to formulate a theorem without any further proof. As a scientist by education (and a blogger only by vocation) I couldn’t ignore such a righteous remark. So, here comes an empirical evidence of Fubini’s law.

Maybe some of you remember my 2013 posting, “inspiration and perspiration”, in which I described the way my blog was getting shape at that time. How the topics to write about usually came while commuting to work on the tramway. And that, when an idea for an article popped up, it took me less than 10 minutes to create an outline on my Blackberry.

Well, in the meantime, technology has evolved and my good old keyboard-operated device has been replaced by a full-fledged smartphone. Yet, I still take the tram to work. My cell phone may have improved, but the traffic to and in Antwerp certainly got worse in the past years. If the weather allows (I’m not a big fan of turning up soaked at the office) I even get off the trolley car 2 or 3 stops too early, and walk the last mile – my fitness tracker corrects me that it’s about 3,000 steps – to work. That’s good for my physical condition, helps me think more clearly, and lets my creative juices flow.

There’s one big difference compared to 2013 (apart from me carrying a step counter): instead of typing down my thoughts, I simply record them now with the voice-recorder app on my phone, and write out the transcript when I arrive at the office…

Fubini’s law. Quod erat demonstrandum!

Please, note that I self-dictated a rough version of the above text on my phone while commuting this morning, then polished the transcript, and published it on WordPress. The whole process, including a healthy walk, took me a little less than two hours.
