I recently turned 60. I don’t pay much attention to my birthdays but this one is a little special because it signifies that by almost any measure I am now officially an old person, a member of a group a subset of whom has been annoying the hell out of me for a long time: greedy old people.

Let me make it quite clear whom this rant is targeting. It is not aimed at old people who after many decades of hard work are even now struggling to make ends meet on their meager savings and social security checks, some of whom have to continue working well past normal retirement age at dead-end and physically demanding jobs which take a toll on their bodies, in order to obtain the basic necessities of life, such as food and shelter. Those people can leave the room because my words are not aimed at them. [Read more…]

Studies “indicate that across a wide spectrum of the population and independent of local crime rates, viewing local television news is related to increased fear of and concern about crime.” That is consistent with my personal experience. I hardly ever watch TV and definitely not the local TV news. As a result, I tend to be less fearful of crime than those who watch the steady diet of fear-mongering that local news channels depend upon in order to get ratings.

I also live in a quiet tree-lined neighborhood in a middle class community with people walking their dogs and children playing on the sidewalks, and all these feed into the impression that one is living in a crime-free area.

Although I am not a soccer fan, I watched the World Cup soccer final between the Netherlands and Spain. I had nothing better to do last Sunday afternoon and thought that I should at least see the culminating event of something that had been engrossing the entire world for a month.

I was surprised at how much I enjoyed it, although the game itself was not that great and the amount of roughness was excessive (especially by the Netherlands), even allowing for the absurd histrionics of players who collapse on the ground (referred to as ‘flopping’) and writhe in agony when tacked for the ball, as if they received a fatal injury, only to jump up and continue playing normally once the referee has penalized the tackler. Surely veteran referees must be aware of all this gamesmanship and discount it when awarding penalties, so for whose benefit is all this acting?

On the radio yesterday morning I heard a report on camps designed specifically for children who have recently had a bereavement in the family to attend with other similarly situated children. The camps will be staffed by people trained in grief counseling and the children will be encouraged to express their feelings through artwork and conversations and even cry.

Well, the great drama of where LeBron James would play in future years has mercifully come to an end. There must not be a single person in America, however remotely located or disinterested in sports, who escaped from the endless speculation that culminated with an actual TV show where he revealed his decision. Surely the last was an act of egotism that has not been exceeded by any sports figure?

In the seminar that I teach that deals with scientific revolutions, one of the difficult questions that we grapple with is how to distinguish science from non-science. In other words, if we have two boxes, one labeled ‘science’ and the other ‘non-science’, can we establish some criteria that will enable us to take any given theory and determine which of the two boxes it should be put into? To be able to do so requires us to establish the existence of both necessary and sufficient conditions for something to be considered science.

If we have only necessary conditions, then any theory that does NOT meet those criteria is definitely not science so it goes into the non-science box. But if it does meet just necessary criteria, all we can say about it is that it may or may not be science. i.e., we do not know which box to put it into. So for example, the commonly accepted idea that scientific theories are materialistic and generate predictions that can be tested are necessary conditions. This is why any theories involving supernatural entities or that are untestable tend to be immediately classified as non-science. But all theories that are materialistic and testable may not be science. For example, the idea that soccer fans are intrinsically rowdier than football fans is not a scientific theory (in the usual sense we use the words) although the methods of scientific investigations (such as statistical analysis and correlations) may be used in seeing if it is in fact a true statement.

Similarly, if we have criteria for sufficiency and a theory meets those criteria, then it goes into the box marked science. But if it does not meet the criteria, it may or may not be science, so again we do not know which box to put it into. As an example, if we say that a theory is science if it has been cited as the reason why its inventors were awarded a Nobel prize, then quantum theory would be scientific without a doubt. But what about the theory of relativity? It has not been cited in Nobel awards so by our rules we cannot definitely say if it is or is not science.

This is why we need BOTH necessary and sufficient conditions to be able to make unambiguous statements that theory A is science while theory B is not science..

One would think that it might be easy to simply make a list of necessary conditions and say that if a theory meets ALL of those necessary conditions, then that is sufficient. But it is not that simple. What complicates things is that any demarcation criterion that tries to distinguish science from non-science would have to be such that all theories that are commonly accepted as science (such as Newton’s laws of motion) would meet the criteria and be included while those that are commonly thought to not be science (say astrology) are excluded. Trying to ensure that existing theories go into the correct boxes is where the difficulty arises because there are always difficult marginal cases.

Finding necessary and sufficient conditions for science has been so difficult that some have declared this problem to be either insoluble or not worth the effort to solve it.

In teaching these somewhat abstract concepts of necessary and scientific conditions, I try to give my students a more down-to-earth parallel by posing to them the question: Is cheerleading a sport? This usually generates a lively discussion and they soon realize that in order to answer this question, they need to arrive at necessary and sufficient conditions for what makes something a sport or non-sport and they quickly discover that it is hard, if not impossible, to do so. And the difficulty is exactly the same as that confronting demarcation criteria for science. While it is possible to make prescriptive lists of conditions for what constitutes a sport, what complicates things is that whatever conditions we arrive at should also be such that things that are commonly accepted as sports (say tennis and soccer) and those that are not (drinking a beer or taking a nap on the couch) fall, using those criteria, into the correct boxes. And there are some tough marginal cases, not just cheerleading. Is chess a sport? Is the card game bridge a sport? (Both have applied to be part of the Olympic games.) How about video games?

It turns out that my classroom discussion question of whether cheerleading is a sport is not a purely academic exercise. It is actually being argued before a federal judge in Connecticut. The reason is that Quinnipiac University has been accused of subverting the requirements of Title IX, the federal legislation that requires colleges to provide some level of equity in support of women’s athletics. The university cut costs by classifying the high-numbers, low-cost, women-dominated cheerleading as a sport, enabling them to eliminate other women’s sports (such a volleyball) that cost more per student. The women’s volleyball team has challenged the university’s classification of cheerleading as a sport and this is what has led to the lawsuit.

In arguing the case, we see the same necessary and sufficient arguments surfacing.

While physical effort and ability are a given for many of the high-level gymnasts who cheer, Title IX has specific criteria for what counts as a sport when it comes to equity in athletics: a program must have a defined season, a governing organization, and feature competition as its primary goal. Competitive cheer is not recognized by the National Collegiate Athletics Association (NCAA) as a sport. Nor does it have a governing body: two versions of organizations that have filled the role have been associated with Varsity Brands, Inc., a for-profit company that sells cheerleading gear and hosts up to 60 “national championships” a year. To amplify its case that competitive cheer can indeed count as a varsity sport, Quinnipiac has joined with seven other schools to form the National Competitive Stunts and Tumbling Association, which is intended to be a new governing body for the sport. Four more schools need to sign on for it to be recognized as a legitimate governing body, and the sport itself to be seen as “emerging.”

It looks like what Title IX has tried to specify are just necessary conditions which, as we have seen, can only definitely say if cheerleading is not a sport. It is not clear if it says that if an activity meets ALL the necessary conditions, then that is sufficient to make it a sport.

Whatever the outcome, Quinnipiac University should be ashamed of itself for trying to subvert the spirit of Title IX and eliminating women’s volleyball.

But what I am really curious about is how the judge is going to arrive at a verdict. Will he be able to specify necessary and sufficient conditions and thus arrive at demarcation criteria, something that has so far eluded my students and me? If so, I will gladly say that you’re a better man than I am, Gunga Din!

POST SCRIPT: Who is an atheist?

My adopted hometown Cleveland has a serious self-esteem problem despite the fact that I have found it to be a nice place to live and raise a family and have been very happy here. Of course, it has many real problems that it shares with other mid-sized cities in the northeast, such as the poor economy, the effects of the housing crisis, schools in trouble, and declining population coupled with rising unemployment.

I like a lot of the conveniences that modern technology provides. At the same time, there is so much new stuff that is coming out that I feel reluctant to waste my time learning things that will prove to be transient. I am also somewhat cheap and tend to wait until the dust has settled and only the truly useful is left standing before spending money on it. So an early adopter I am not. I tend to keep an eye on trends but not adopt anything new unless I think I really need it or it solves a problem that I have or it looks like something that will really improve my life.

Personal GPS navigation systems have so far not passed that threshold. Yes, I can see that it might be fun to have but so far I am not persuaded that it is a must-have.

Last Friday, someone knocked on my office door. He said that he was looking for a conference that the university was hosting. I knew that there was nothing going on in my building and asked him why he had come there. He said that this was the place that his GPS has sent him to. I asked him if he could give me the name of the building where it was to be held or the people organizing it so I might be able to help him more easily. He said no. He had simply plugged some information into his GPS device and followed its directions to the end, which happened to be my building.

It so happened that I was able, from the topic of the conference, to track down the exact location and send him on his way. But I marveled at his total dependence on technology.

He is not alone. Recently my cousin was driving to New York City from Toronto for a wedding that I also attended and depended totally on his GPS system to get him there. For some reason, the street address of the hotel was not the address that you are supposed to insert into the GPS to get accurate directions, but he overlooked that and as a result he got lost and spent several wasted hours wandering around NYC (at the end of a long drive from Toronto when everyone in the car was already tired and irritable) until he found the hotel. It had not occurred to him to carry a map with the location of the hotel on it or to use MapQuest or similar sources to gets directions as backup.

While these two cases were benign, overdependence on GPS can be potentially deadly as one Oregon couple found when they blindly followed their GPS directions into a remote forest road and became stuck in the snow for three days before they were rescued.

I myself do not use GPS because I find that I am perfectly able to get to places with just street maps or with help from MapQuest. I also dislike the idea of voices breaking into my consciousness when I am driving and telling me what to do, when most of the time I don’t need directions. Before I leave to go anywhere unfamiliar, I make sure that I have located my destination on a map and created a visual map in my head, and I take actual maps with me as a backup.

There s nothing wrong with using GPS. What surprises me is that some people are totally dependent on it and have no plan B, no backup, if the GPS goes awry.

POST SCRIPT: Wedding speeches

Over my lifetime I have attended many weddings and listened to quite a few speeches and I must say that That Mitchell and Webb Look captures their over-the-top praise nature well.

Today marks the fifth anniversary of this blog, so I thought I would pre-empt my series on the end of politics where I excoriate Obama and the Democrats and indulge in some self-indulgent musing about the whole blogging exercise and my contribution to it.

After some initial hesitant steps when I was not sure what I would do with this new medium, I soon settled into a routine of one op-ed length essay of about 1,000 words on a single topic each weekday. Apart from repeating some postings when I am on travel or for holidays, I have not taken a break. As a result, I have now written about 1250 essays and well over a million words. But I realize that this type of blogging is not natural for the form.

The big advantage of a blog is that it can be a way of providing immediate and informed commentary on news, whereas newspapers and magazines have lag times that can be quite considerable.

The second advantage is that a blog post can be of any length. Magazine and newspaper and journal article are of the ‘long form’ type and there are often constraints of length that one must conform to, about 800 words for op-eds, or 1,500 or 5,000 or 10,000 word lengths for magazines and journals. But a blog can be any length at all, from just a few words to thousands. So you can say exactly what you want to say, no more, no less, as the need arises, which can be enormously liberating and prevent needless verbiage.

What I have done is seemingly take the negative aspects of the long form essay (fixed word length and more analytical pieces) and used it as a basis for my blog. I am not entirely alone in this. Glenn Greenwald’s excellent blog (which should be a must read for anyone) also has usually one long (often very long) analytical piece each day, but his deals with breaking news on the legal and political fronts. I often learn about breaking news from his blog. I cannot do the kind of quick analysis that Greenwald can (he is a constitutional lawyer and has a lot of expertise at his fingertips) except on rare occasions, so I rarely publish things in such a timely way.

So why I am blogging in this unnatural way? Partly out of necessity. It takes me a while to digest information and make sense of it. I jot down ideas that I think are interesting and may have some insight into, and sometimes think about them for weeks or even months before I write them up. Also I have other work to do so that I cannot spend a lot of time keeping up with breaking news or cruising the web picking up interesting tidbits to comment on.

I know that every one is busy so it has been my goal to not waste the reader’s time. I arrived at the approximately 1,000-word length because it can be read in a few minutes. Since what I write about usually deals with old news, to add value, the blog post should contain things that are at least useful or new or interesting. One way of adding value is to provide at least some original analysis. As someone for whom teaching is in the blood, I also try to explain science or other difficult topics in ways that I hope will be clear and helpful to those who do not have the time to invest in learning these things on their own. The combination of trying to explain something in depth while restricting myself to the daily word limit has resulted in the many multi-part series of posts.

I also try to write the post as well as I can, given the limited time that I can devote to it, because I know how annoying it is to read something that has typos, factual errors, poor grammar, and generally looks sloppily done. I feel that such writing is an insult to the reader. So each post is rewritten and edited several times before it is posted, which is another reason that I rarely comment quickly on breaking news stories. I also try to be as accurate as I can about the information presented and give the sources so readers can follow up for themselves. All that takes time.

The benefits of blogging for me personally have been tremendous. In researching the information for the posts and in trying to explain things to others, I have learned a lot myself. I think I have also become a much more proficient writer as a result of the practice I have gained. The blog posts have often formed the first drafts of articles that I have subsequently published in more formal venues. Even my recent book God vs. Darwin began as a series of blog posts.

In the process, I have learned a lot from the readers and made many new contacts and renewed others thanks to people finding the blog.

At each anniversary I wonder how long I can keep up the pace. My main worry is that I will run out of things to say and start repeating myself. So far, I think I have avoided that danger. It has been fine and fun so I plan to keep going.

So thanks, everyone, for reading and commenting and sending me information. Here’s to another year!

POST SCRIPT: Book signing and talk

I will be giving a talk and having a book signing on God vs. Darwin: The War Between Evolution and Creationism in the Classroom at the Joseph-Beth book store in Legacy Village in Beachwood, Ohio at 7:00 pm tomorrow (Wednesday, January 27, 2010).

I would enjoy meeting any readers of this blog who can make it.

(My latest book God vs. Darwin: The War Between Evolution and Creationism in the Classroom has just been released and is now available through the usual outlets. You can order it from Amazon, Barnes and Noble, the publishers Rowman & Littlefield, and also through your local bookstores. For more on the book, see here. You can also listen to the podcast of the interview on WCPN 90.3 about the book.

Because of the holidays and travel overseas where internet access will be sporadic, I am taking some time off from writing new posts and instead reposting some of my favorites (often edited and updated) for the benefit of those who missed them the first time around or have forgotten them. New posts will start again on Monday, January 18, 2009.)

Baxter and I would like to wish all the readers of this blog our best wishes for the season. May all of you find peace and happiness.

We live in a world divided by conflicts based on religion, ethnicity, and nationality. But all these divisions are of human creation that merely serve to set groups of people up against each other by encouraging appeals to tribal loyalties. They have at best merely superficial meaning, and all came into being within the last four thousand years or so, a mere instant in the vastness of time that life and the universe have existed.

Contrast the divisiveness of religion, ethnicity, and nationality with the unifying effects of science in general and evolution in particular. If everyone were to accept the truth of evolution, that each one of is connected to every other living organism that lives now and has ever lived by the Darwinian tree of life, perhaps we can overcome tribal feelings and move towards a truly just and peaceful world.

We are fortunate that we are alive to experience life in its gloriousness. We should strive to enable everyone to experience that life to its fullest, free from want, and with the basic needs of food, shelter, clothing, education, and medical needs met. We can do that it we do not waste so much time and energy and resources on parochial interests at the expense of the general good.

So let’s spread that message.
