Wearables are on the rise currently, when writing this blog, Google recently released its Fitbit Air, rivaling the Whoop. However, most wearables has been until now been measuring essentially the same biomarkers, skin temperature and heart rate. Companies usually compensate for the lack of direct physiological measurements by adding and accelerometer and generating a lot of data, then throwing that to an AI model to predict a all sort of conditions about us. It works, to some extent, but at some point you would need to add a new biomarker to extract more about the human body. Sweat contains loads of information about the human body, the most obvious are electrolytes, but it also contain some metabolites such as lactate and glucose. It also contains traces hormones like cortisol, which is how dogs sense stress signals in humans. It also contains proteins, dead cells, leftover sunscreen, dust, you name it. What makes sweat interesting also make it hard to extract information from. Using ...

  One of classical music's great mysteries is J.S. Bach's unfinished piece in The Art of the Fugue musical work; specifically the Fuga a 3 Soggetti piece which ends rather abruptly . Probably many authors, artists or composers leave unfinished work before they're ready to meet their maker, but what leaves this specific unfinished work even more puzzling is that the author, J.S. Bach, finished it with the musical motif B-A-C-H  (B♭–A–C–B♮ is the english notation). Did Bach intentionally leave his name as the last motif just so he can laugh in his grave while we, centuries later, still squeeze our minds thinking about it? Hard to say, but it did indeed inspire many composers after him to try to finish the work, more than 80 attempts in fact [ 1 ]. Since Bach is famous for his mathematical precision in composition, this blog will approach completing the fugue as a mathematical puzzle to solve. I will take a probabilistic approach using Markov chains, try state of the art AI ...
