Good new, bad news, or not news at all?

June 14, 2013

If you’re interested in manufacturing technology or the role of manufacturing in the economy, you may be interested in an article recently published in the Wall Street Journal, “Advanced Manufacturing: The New Industrial Revolution.” But what I found nearly as interesting as the article was (as is often the case) the different comments readers made about it.

The article itself is about how technology is changing the nature of the manufacturing process. Inexpensive electronic components make it possible for machines to monitor themselves, and humans located at remote locations can respond to problems that do arise. Additive manufacturing makes it possible to produce parts in shapes that were not feasible before, or that previously cost too much to be practical.

High-tech socks

June 2, 2013

When you hear “high tech,” what do you think of? Computers, probably. Or at least something with a microchip in it – which could be almost anything these days. But socks?

I buy cheap socks. Considering that I wear pants most of the time, and my socks are seen so little that I’m mostly just interested in the color not contrasting too much with my pants, it hardly seems to make sense to pay extra for fancy socks.

Plus they stick around for very long, at least not in good shape. The last set of socks I bought, I think they had holes in the toes by the second time I wore them. Or they disappear when I wash them (only one of them, of course – and probably the one that doesn’t have a hole in it).

Until I read this article in the Wall Street Journal, I figured my sock troubles are just part of life, and a fairly small problem in the big scheme of things. But now I wonder, should I try some of the newer, high-tech socks?

Mending made easy

December 26, 2012

For eight years I lived without a sewing machine. I had bought one used, a long time ago, back when I got my first full-time job and my first car and my first rented room. I had never-ending problems with the tension, even after getting it supposedly repaired at a shop that specialized (among other things) in fixing sewing machines. After I had children, I had no time to sew my own clothes, and I used the machine only for mending. It was such a pain to use that some mending jobs seemed easier to do by hand. When we moved from Michigan to Illinois eight years ago, I gave the thing away.

But some mending is not easier to do by hand, and the pile of unmended clothes grew. I looked, sometimes, at the sewing machines sold at Walmart, and wondered if a new machine might work better than that old one. But I remembered the man at the sewing machine repair shop telling me I had a good machine, made out of metal instead of plastic. The newer, plastic machines, he said, gave a lot more trouble. That was easy to believe, considering what I hear people say about newer models of so many other products.

The pile of mending got so big that I had been thinking, recently, of taking it to someone who does sewing to make some extra money. Somehow we never settled on a time for me to get the stuff to her, though – we both have busy schedules. Then a few weeks ago, at the Boy Scout Christmas campout, one of the Scout mothers was there with her sewing machine, sewing patches and badges on boys’ uniforms. It looked like it worked well, and I asked her about it. She was very happy with it, and explained that the electronics took care of the tension, and pretty much everything else.

Books: The Neanderthal Parallax

November 9, 2012

Having previously enjoyed Robert Sawyer’s WWW trilogy, I tackled his Neanderthal Parallax trilogy over the past two weeks. Like Sawyer’s other science fiction, these novels are based on real science, however speculative some of it may be. As in the WWW trilogy, one of these areas of speculation is the origin of consciousness.

In the WWW trilogy, the theory that is explored posits a relatively recent origin of consciousness, less than three millennia ago. In this trilogy, it is set about 40,000 years ago, and is thought to be the result of a collapse and subsequent reestablishment of the earth’s magnetic field. Along with consciousness and therefore conscious choices came the first split between parallel universes.

As chance would have it (this being based on quantum theory), in our universe, it was our ancestors who developed consciousness. In the parallel universe, it was those we call Neanderthals. Our own ancestors, in that universe, failed to develop consciousness and subsequently died our, presumably (according to Neanderthal scientists) due to lower intelligence, our cranial capacity not allowing for as large a brain.

Books: Same Time, Same Station

October 17, 2012

I ended up reading this book about the early history of television because I had been reading a book about teaching Sunday School. I know that seems like an unlikely jump, but there was a logical connection. Honest!

(The book I was reading about teaching Sunday School recommended, more or less in passing, that if you use puppets, not to have them talk about God. I emailed the author to ask why. Her response – that puppets are not real so they can’t have a relationship with God – did not entirely satisfy me, so I found an internet forum about puppets and found someone who seemed to use puppets in Christian ministry. I joined the forum so I could contact him by email, and asked him about this. He not only saw nothing wrong with having puppets talk about God, he told me that the word marionette comes from the name Mary because early Christians used puppets to teach. Wanting to learn more about that history, I looked for books in the library catalog about marionettes. One was about Howdy Doody, a show I’ve heard about but never seen. I wondered if I could find a DVD I could borrow with episodes from Howdy Doody. My search didn’t turn up much in the way of DVDs, but it did list Same Time, Same Station, a book about the early decades of television.)

The topic  of the book was interesting, but just barely enough to motivate me to finish reading the book. Despite what the flyleaf says about “Baughman’s engagingly written account,” I found it far from engaging. The flyleaf also reveals that Baughman is a historian and a professor; perhaps he wrote this with students of Journalism and Mass Communication in mind.

I’m not sure I’ve ever read a book with so many endnotes. They take up over 25% of the book! That means, of course, the that text is chock-full of quotes, historical details, and other data that may be of interest to the historian but probably not to the average reader. Often I thought Baughman could easily make his point with a single quote. But he piled one on top of another. I wondered if he was trying to use every possible historical citation, and if so why.

I did learn some interesting facts about the early history of TV, however. Having grown up in the 60′s and 70′s, I took the division of stations into VHF and UHF for granted. I had no idea why I watched NBC on UHF and CBS on VHF. (The third network, ABC, had no local station, and only came in very fuzzily on one VHF station and one UHF station – and then only on a good day.)

IQ and the Flynn Effect

September 23, 2012

Unlike a lot of people, I’ve always enjoyed taking IQ tests. Earlier this year, salaried employees in the department where I worked had to take a series of tests that were supposed to measure one’s leadership potential. Some of them dealt with experience and ambition in relation to leadership, and one test measured abstract reasoning. We were told not to worry about this last test, that it was only one piece of the larger picture. But for me, that test was the best part of the whole process.

I’ve never wanted to get into management, so I have naturally not sought out the kind of experiences the other tests were asking about. What leadership positions I’ve been in have usually come sort of by default – because I was the only one willing to do it, or because I seemed the “obvious” choice (president of math league in high school because I got the highest scores, and Bible study leader at church because I am the pastor’s wife).

The kind of abstract reasoning and pattern recognition used in a certain kind of IQ test, however, is something I’m good at and I enjoy doing it. Partly I enjoy it because I know I do it well, but it’s also the kind of puzzle I enjoy solving. I think the test I took (a long time ago) that was supposed to measure aptitude for computer programming was of this nature. I not only did very well on it, but I enjoyed taking it so much that I figured I would enjoy computer programming also.

I always assumed, growing up, that such tests measured some actual trait labeled intelligence. That’s what the people who made and administered the tests thought, of course, and I suppose most other people did also, until psychologists began to recognize that intelligence was really made up of a number of broad abilities.

I remember learning about the idea of multiple intelligences, a number of years ago, when I was looking for resources for teaching Sunday School. On the one hand, it makes sense to recognize that different people learn best in different ways, which seem to be at least somewhat related to this idea of multiple intelligences. On the other hand, it seems to be stretching the word intelligence to the point that it doesn’t mean very much, to use it for abilities that do not deal with reasoning.

No doubt society has often inappropriately treated people with high abilities at abstract reasoning as superior to those with other kinds of abilities, and it is good to recognize the value of those other kinds of abilities. But it should be possible to correct that tendency without divorcing the word intelligence from its traditional meaning related to reasoning ability.

All that was somewhat in my mind as I started reading an article in the Wall Street Journal yesterday. James Flynn discusses the fact that IQ scores have steadily risen over the decades, and asks Are We Really Getting Smarter? I had not realized that scores were, in fact, increasing, because the tests periodically are updated and re-standardized, so the scores appear to remain constant. Someone who scored well on a test today would have scored even better on one of the older tests. But someone who scored well several decades ago would not score nearly as well now.

Flynn was the one who initially drew attention to this trend, though it was the authors of The Bell Curve who coined the term Flynn Effect, in recognition of the work done by Flynn to document it. A number of different explanations have been offered, but Flynn’s own explanation, in the WSJ article, is that modern education has trained people do perform better at abstract reasoning activities.

If IQ tests really measured something innate, then people who lived a hundred years ago should have performed just as well. (Better nutrition and protection from infectious diseases have been offered as explanations for the increases, and they may account for part of it, but improvement in those areas does not seem to follow the same pattern of gradual, linear progression seen in IQ scores over several decades.) People in a less technological society did not have all the knowledge we do, but they should have had similar aptitude.

Language and cultural references are sometimes given as explanations for certain subgroups of society not performing as well, but the non-verbal problems that use only geometric shapes should eliminate that issue. Yet as Flynn points out, people who have not gone through modern education would have difficulty understanding what in the world such questions were about.

We are trained at such a young age to recognize abstract patterns, finding similarities in unrelated objects (similar shape or color, for instance), that it is hard (for me, anyway) to imagine lacking that kind of recognition. But it makes sense what Flynn says: if success in life is based on ability to hunt animals, or make furniture or clothing, the idea that the moon and a cantaloupe have something in common (because they are both round) may sound like nonsense.

Of course, in a technologically advanced society, abstract reasoning is an important ability in many jobs. But it’s good to be reminded that IQ is a useful measure only to the extent that what it measures is useful.


Back to school

September 13, 2012

I’ve always liked the beginning of fall and a new school year. Refreshingly cool weather, a fresh new start with new classes, new subjects, new things to learn, and new goals to reach for.

Except for an online course I took a few years ago, it’s been a long time since I went back to the school in the fall – except for the “back-to-school” nights at my sons’ schools, which have a whole different feel for a parent than a student. I’ve always found things to learn, but generally not in the intense fashion that I associate with going “back to school.”

I’m back on a college campus this fall, but not as a student. Last week I started a new job, on the staff of Black Hawk College. I’m thrilled at the opportunity to be part of the learning environment, and I appreciate the community college’s commitment to making learning accessible to many people who for one reason or another face significant if not insurmountable barriers to becoming a student at a traditional four-year college.

Why blogs are better than Facebook

September 2, 2012

For years I have had a circle of virtual friends. We “met” at worldmagblog, later renamed World Community. We gathered daily, or as often as time or interest allowed, to discuss news, issues, events in our personal lives, faith, and anything else that we chose to talk about.

Some of us got in touch with each other directly through email. We sent cards (real ones, mailed from one person to the next for a genuine non-virtual signature) to someone getting married. Some of us have even met in person, when travel plans included a stop near where someone else from the blog lived. Gifts have been given. Many prayers have been sent up for each other.

It was a constantly shifting community, with new people joining and others drifting away. But it was tight enough that when one regular didn’t show up for quite a while, someone else became concerned enough to find out where she lived to make sure she was OK. It didn’t take the place of our in-person relationships, but when there were joys or griefs in our lives, it was one place we went to share our happiness and receive the comfort of knowing others cared.

I put all this in the past tense, because this past week, World Magazine informed our community that they were no longer going to host our daily gatherings. Their new site has a policy of comments by subscribers only, and no open threads (i.e. commenting is expected to be relevant to a particular news story). They suggested social media such as Facebook for the purposes we had used their open threads for.

Books: WWW Trilogy

August 7, 2012

I won’t say that Robert Sawyer is my new favorite author – that’s still Dean Koontz. But Sawyer is now my favorite science fiction author. His WWW Trilogy (Wake, Watch, and Wonder) is thought-provoking, full of real science as well as science fiction, and just plain good story-telling.

The trilogy chronicles the emergence of a conscious mind that somehow exists in the infrastructure of the World Wide Web.Because it has all the resources of the Web at its disposal, it has capabilities humans – and human governments – can only dream of. People use the internet to collaborate, but their efforts are puny next to a “being” that can instantaneously access any and all data of all kinds residing on any computer anywhere in the world so long as it is connected to the internet.

The question is whether such a being will use its vast power in ways that will help or hurt human beings. Because it is not localized in any particular part of the Web, it cannot be controlled.  Without risking devastating effects on the worldwide network of computers that are essential to commerce today, it cannot be removed. But some people think such a powerful non-human intelligence is so dangerous that it is worth the risk involved in destroying it.

Test your typing

August 1, 2012

I was filling out an online job application, and one question asked for my typing speed. I was sure it was over 40 wpm, but thought it would be nice if I could find some kind of typing test to get an accurate number. I quickly found one on the internet, which has the great advantage of not only being easy to use but actually fun because the text you have to type is actually interesting.

I mean, wouldn’t you get a smile on your face as you found yourself typing out this sentence?

Basically, a tool is an object that enables you
to take advantage of the laws 
of physics and mechanics
in such a way that you can seriously injure yourself.

Not every test (I’ve tried five so far, I don’t know how many there are in all) is equally humorous, but they beat some of the dull text I’ve copied in typing tests before.

Check it out here: http://www.learn2type.com/typingtest/typingtest.cfm. I don’t know whether I type any better when I’m smiling (the humor is subtle enough so I don’t have to worry about laughing too much to keep my speed up), but so far my best score was a surprising (to me) 70 wpm.
