Albums you missed: John Stewart – Cannons in the Rain

This is the first post of a recurring series that I plan to run on Saturdays, looking at albums that remain on my iTunes playlist in original running order after a lot of years. For this first one, a look back at John Stewart, not the comedian and Daily Show host, but rather the less-well-known songwriter of one of the… Read more »

Education and the fixed-cost dilemma

      1 Comment on Education and the fixed-cost dilemma

I wrote a post back in February that looked how an accounting problem called the fixed-cost dilemma skews many medical costs like drugs and ambulances. The same problem occurs in spades in higher education, and that is the focus of this post. If you are going to advocate for “free college education,” I suggest that it is very helpful to… Read more »

Education and the high price of the credential

      1 Comment on Education and the high price of the credential

In a prior post, I noted that much of the pure “education” delivered by a college or university is alternatively available from other sources for little or no cost. What then are all of the tuition dollars, state funding dollars and student loan dollars paying for? If we are looking to fund “free college for everyone” then where is that… Read more »

Education has always been free

      5 Comments on Education has always been free

I was representing my publisher employer at a technology meeting at the dawn of the commercial internet in the mid-1990s when I heard the popular technology guru Esther Dyson presciently say that “the price of information always trends toward zero.” That prediction was not good news for many book publishers like mine, but it has certainly come true in the… Read more »

Politics informed by math #5 – Small conspiracies

In an earlier post I suggested that you can likely doubt that most alleged grand conspiracies are real on probability grounds alone, as the number of one-to-one connections requiring “trust against a lie” grows factorially. By the same logic, the smaller the conspiracy, the better the odds of keeping the trust factor intact. In this post I will look at a… Read more »

Tax avoidance, tax evasion and Trump

      No Comments on Tax avoidance, tax evasion and Trump

The New York Times recently published a deep dive into some of the questionable tax practices of the Trump Organization going back to the days of Donald’s late father Fred Trump and his transfer of many millions of dollars in assets to his children through methods of dubious legality. [1] The gist of the story is that first, the Trump… Read more »

Politics informed by math #4 – Grand conspiracies

The political fringes are dominated by conspiracy theories that far too often encroach on the usually more reasonable political middle. In this post I want to look at some math behind grand conspiracies, which involve many people keeping a secret, as contrasted with small conspiracies, which only require a small, tight group to maintain. One classic example of an alleged grand… Read more »

Politics informed by math #3 – “Money is speech”

      No Comments on Politics informed by math #3 – “Money is speech”

Supreme Court Justices may know the law, but I am not convinced that they know math. This post is a little exercise in the math behind the conservative dictum that “money is speech.” To cut to the chase, and if indeed, “money is speech,” then a family whose net wealth in 1963 was in the 99th percentile of U.S. families… Read more »

Politics informed by math #2 – Medicare-for-all

      No Comments on Politics informed by math #2 – Medicare-for-all

“Medicare-for-all” has become a common campaign promise on the political left but it suffers in the details, first from any widely-accepted definition, which can range from a (not-so-simple) “public option” to a complete nationalization of the healthcare insurance payments system. Second, all of its configurations that I have investigated suffer from an apparent naivete or lack of understanding of some… Read more »

Brett Kavanaugh, moral luck and the veil of ignorance

      No Comments on Brett Kavanaugh, moral luck and the veil of ignorance

In this blog I have visited several times the intersection of mathematical probability with what we often call “divine justice” (also known as theodicy). For instance, the odds being diagnosed with any of several types of cancer resemble statistically the winning of a cruel lottery, with statistical annual diagnosis rates per 100,000 people eerily unchanged from year to year. Or take… Read more »
