As the country nears Labor Day, kids all around the country are gearing up to go back to school, … maybe.  As summer draws near to it end, parents everywhere are buying school supplies and readying their children for school, … maybe.  Educators are writing syllabi and lesson plans, fretting over lectures and homework, and are preparing to teach, … maybe.  For the first time in most anyone’s living memory, the back-to-school ritual has encounter an insurmountable snag and so, a new normal has descended.  Will we cope with this new wrinkle in the education system?   Maybe.  We at Blog Wyrm can only hope for a few things.  First, that parents, kids, and educators stay as healthy as possible, both physically and mentally.  Second, perhaps this new normal will cause us to finally overhaul the education system and give it its long-overdue reform.  Maybe that will happen.

Now onto the columns.

Aristotle To Digital begins exploring an interesting machine learning system – naïve Bayesian classification.  A rather simple algorithm to implement, this supervised learning technique is popular because of its high value – it requires only a relatively small amount of training data and it performs reasonably well.

One of the most important places where market inefficiencies motivate profit-seekers to really go the extra mile is the financial markets.  The lure of big money without actually having to transport any concrete good makes this an excellent laboratory for studying arbitrage opportunities and how macroeconomic forces come into play.  Common Cents explores the basic mechanism by which the securities bought and sold in these contexts are valued.

Incompressibility is a central pillar of common fluid models.  However, every good thing comes to an end.  This month, Under The Hood begins a multi-part look at compressible fluid flow.  This new regime adds a bit new spice as the energy equation comes front and center bringing thermodynamics along with it.

Enjoy!
