Issue 101 – Oops

The narrative below was written and ready for public viewing on schedule.  However, things being what they are, it never saw the light of day when the columns did.  Oops!

Well April is upon us and the world is still topsy-turvy.  At least the weather is beginning to change and the hope for warmer days is ahead.  As we all adapt to social distancing, online learning, and massive stagnation in the economy, it is worth remembering that we still have many blessings.  Despite the strains on our medical system, on our infrastructure, and on our common spiritual and mental well-being, most of us are healthy and sound and will see this troubling time through.  Far more concerning is whether many of our most basic rights will make through unscathed.  That, of course, is up to each of us and only time will tell.

Now onto the columns.

Random chance.  A common phrase that gets bandied about in routine conversation.  But precisely defining what is and is not random is surprising hard to do.  Aristotle To Digital presents a few aspects of the amazingly rich structure found when considering random events with no patterns.

As the Corona virus alters life in the United States, there are things to gladden the soul, to madden the heart, and to disgust common sense and good taste.  As social beings, we can’t help but live in a collective economy where we all depend on each other.  Common Cents presents the good, the bad, and the ugly of living in the socially-distant world of COVID-19.

Somewhere in an introductory physics class, the student briefly encounters simple fluid flow and, typically, Bernoulli’s equation with its accompanying notion of streamlines.  These presentations rarely impart the richness and complexity of real fluid flow, fail utterly to emphasize how important fluid dynamics is in wide swaths of physical research, and sell short the variety of descriptions and tools that practitioners use to understand.  This month’s Under The Hood tries to address this last point by looking at path-, streak-, and streamlines and showing how even simple-looking situations can lead to some counter-intuitive conclusions.

 

Issue 100: Due Process

We at Blog Wyrm rarely comment on politics and, when we do, it usually on the lower-case politics (how we interact with each other generally) and not upper-case politics (focusing in on some politician or another).  However, we can’t always avoid calling the situation as we see it.  Right now, be it the Iowa Caucuses or the Impeachment of Donald Trump, the conviction of Harvey Weinstein or the disgrace and death of Jeffery Epstein, or the cancel culture so rampant on social media it is our duty to uphold the central principles of the republic.

Everyone is innocent until proven guilty, not only in a legal court but also in the court of public opinion.  Our neighbors, as well as our enemies, deserve to be treated as we would want to be.  Each of us should have the opportunity to have his side of the story heard before the ‘mob mentality’ of modern tribalism concludes that he needs to be exterminated for the common good.

Throughout history, the hysteria found in the Inquisition or the Salem Witch Trials rears its head and sweeps the innocent up with the guilty.  Sentiments like those ushered by the Bishop of Béziers, who said “Kill them all, God will know his own.” become the rallying cry to justify swift retribution untempered by justice or compassion.  After all, one cannot make an omelet with cracking some eggs and vice in the pursuit of virtue        is no vice at all.  As long as the guilty are punished and expunged from the public eye.

And speaking of the guilty, it is important to remember that no matter how vile and repulsive the behavior the person underneath is still a human being and we ignore that fact at our peril.

Enough said… now onto the columns.

One of the weirdest and paradoxical parts of mathematics is the Axiom of Choice. Aristotle To Digital takes a hard look at this controversial, mathematical concept and demonstrates that humans still have a long way to go in dealing with infinity and infinite sets.

The trendy new idea circulating amongst certain circles is the forgiveness of student debt.  Certainly student debt is burdensome and even crushing for students but is forgiveness really the correct amelioration?  Common Cents argues that such a course of action has terrible unseen costs and incentivizes or even rewards behavior bad for society,

Continuing with the concept of vorticity, this month’s Under The Hood looks at the Rankine Vortex and some of the difficult concepts such a simple model brings in its train..

Issue 99: Red Super Bowl

The Super Bowl is upon us this Sunday.  The red-clad Kansas City Chiefs take on the slightly different shape of red clad 49’ers from San Francisco (of course they will be in there Gold with Red highlights jerseys but who cares).  It is odd just how much of the viewing year centers on this one event.  From commercials to parties to football pools the Super Bowl, a uniquely US phenomenon, shows just how free and, sometimes silly, we can be.  Hopefully a good time will be had be most (sadly not by all since someone has to lose).

Christmas Break

In celebration of Christmas, BlogWyrm staff is taking a winter break.  We will be back in the last Friday of January with new columns.  In the mean time, we wish you all a Merry Christmas and may God bless you.

Issue 98: Happy Thanksgiving

It’s that time of the year again.  Football, turkey, and shopping.  We at Blog Wyrm hope that each of you will find time to be really thankful.  Thankful for friends and family; thankful for the modern standard of living; and thankful for the freedom afforded us by living in the finest country in the world.

Now onto the columns.

To make an AI that behaves like a human one must first understand the human.  Specifically, one must understand the structure of the human mind.  And here, old fashioned philosophy leaps to our rescue.  Out from days gone by, Aristotle To Digital shows the three acts of the mind and how they play out in producing what is characteristically human thought.

Hardly a year goes by without Common Cents looking at the origins of Thanksgiving in the need for human beings to be free.  Unfortunately, there are many people who look at the origins of our most unique national holiday look only at the ‘dark side’ of colonization without perspective or sense.  This month’s Common Cents takes one such individual to task.

One of the most interesting concepts in fluid dynamics is the idea of vorticity.  This month’s Under The Hood takes up this concept and examines some of the subtleties using a plain bucket full of water..

Issue 97: Happy Halloween

Well, we are back.  It’s been quite a struggle and we are still not completely recovered, so this month’s columns are a bit shorter than usual.  Nonetheless, we trust that  nobody will object as we ease our way back into the saddle.  Suffice to say, the last several months have been rough and, in the spirit of wishing everyone well, we extend a hearty, Happy Halloween.

Now onto the columns.

Hardly a day goes by without some article, commercial, or advertisement pushing the glories of AI or arguing to us how upping our skills in ML will put us on the fast track for a fat salary.  What isn’t discussed is that AI/ML is only one facet of the real vision.  What exactly is the real vision and what pieces are missing?  Well, read this month’s Aristotle To Digital to find out.

In the last two columns, Common Cents looked at the downsides that accompany the presence of a monopoly in an economy.  Nonetheless, there are good reasons to consider having monopolies in limited circumstances.  This month’s column considers these specialized cases and considers the associated pros and cons.

With the survey of fluids now complete, Under The Hood starts looking at explicit cases that help sharpen the applications of the theory and develop the intuition.  This month’s theoretical laboratory focuses on Bernoulli’s Principle..

Life Happens

BlogWyrm was to resume publishing at the end of August and here it is the end of September and yet no new material.  What is the explanation?  Well, BlogWyrm staff routinely blogs about Philosophy and Computing, Economics, and Physics and an unfortunate diagnosis has given the staff to be philosophical about how modern physics contributes to the economics of health care.

The bottom line is that the staff has had its hands full in August and September but are all set to return in October.  Thanks for all the patience.

Issue 96: Glorious Mother Nature

 

The weather makes frequent appearance in this general introduction posts each month here at Blog Wyrm.  The primary reason is that it is easy to talk about, although, to paraphrase Will Rogers, no one does anything about it.  But one of the compelling reasons to talk about it, besides its impact on day-to-day living, is that sometimes Mother Nature goes out of her way to present the glory and beauty she possesses in a way that one simply can’t ignore.

Such has been her habit for the last several weeks.  About twice a week, she has opened her skies and brought rain down upon the land during my commute home.  Ordinarily the snarled traffic would cause me not end of headache but Mother Nature had a reward in mind.  Just as a certain overpass presented itself in my way, the rain would let up, the sun would emerge, and a spectacular arc would appear (as well as sometimes a fainter arc above and outside the main one).

Rainbow

The above picture can only give on a modest sense of the breathtaking wonder.  Needless to say, it made the whole trip worthwhile.

Now onto our own small wonders the posts, which, hopefully, will make the time you invest in reading them worthwhile.

A recent news story reported that Navy pilots saw hypersonic UFOs off the east coast of the United States.  Once a source of wide-spread skepticism, frequent scorn, and story material for science fiction both good and bad, UFOs have gained a bit of cache in the recent months.  But does that make them any more ‘scientific’ or are they still in the realm of ‘pseudoscience’ and what do any of these terms really mean?  This month’s Aristotle To Digital takes a stab at answer these questions by casting an uncompromising look at what really constitutes scientific inquiry and what problems arise when we blur the lines between science and pseudoscience.

Many people believe they know exactly what is wrong with a monopoly.  But when pressed the answers sound more like a politicians polemic than a hard and dispassionate analysis using the tools the ‘dismal science’ of economics.  Surprisingly in contrast to the way monopolies are portrayed in movies and in the often useless punditry that litters our public discourse, monopolies are really slackers in corporate disguise.  Common Cents continues its multipart analysis of how monopolies work by working with one of the favorite tools of economists the world over  – graphs of supply and demand curves.

Given the wide range of fluid behaviors and the weird phenomena that often crop up assuming a linear relationship between stress and strain rate may seem awfully limiting.  That is until one steps back and appreciates that the two most ubiquitous  fluids on the planet – water and air – often  follow such a Newtonian behavior.  This month Under The Hood explores Newtonian fluids and derives the famous Navier-Stokes equations.

Enjoy!
