Changing something changes everything
Tomorrow is a lot like today, but not always. Beware the law of unintended consequences.

Scientists and doublethink
Using different theories at the same time
Scientists, especially astronomers, use several incompatible theories in their calculations. How? And why?
Ends and means
Or, strategy and tactics in photography (and elsewhere)
You have many tasks, large and small, difficult and otherwise. For each one you have to choose a way to get it done. A problem arises when you find such a wonderful means that you forget the end.
Learning from a master
The expert may not be the best teacher
As we mentioned last week, our navigator was out of the office teaching a professor how to use his sextant. Having decades of experience in both the observations and the calculations involved, he certainly has a firm grasp of the subject. But that’s not always the quality you need in a teacher.
The artist and her tools
Our photographer accompanied a pair of artists on a picture-taking expedition this past weekend. As expected, he has observations to make about old and new technology. But he was also driven to more general musings about the relationship between artists, their visions and their tools.
No more libraries?
Electronics replaces paper
For many purposes, books are no longer necessary. That is, for entertainment or learning one need not find or carry around a pile of bound paper. The internet contains a vast landscape of information and e-books are ubiquitous. So do will still need places to borrow paper books from—libraries? Or librarians?
No more trade-offs
It’s easier when you can have it all
Life was more complicated in the old days. Not only were many things more difficult and tedious to accomplish, often you had to work out which of several methods you should use depending on what you really needed done. It’s much easier now. Really.
Learning the stories
Using words instead of math
Here on the 100th birthday of General Relativity our science consultants were pondering why Relativity and Quantum Mechanics were so easy for them to accept but so hard for people a century ago. Certainly it’s not because we’re more insightful or brighter scientists–quite the opposite. Nor is it that we’re better at math; again the opposite is true, and these are highly mathematical subjects. We finally concluded that we’re comfortable with the theories because we were told the stories, word-descriptions of what the math means, from an early stage and so the theories never seemed impossibly strange. The stories are important. But it’s also important for both scientists and laymen to understand their limitations.
But why pictures?
A photographer explores the ubiquity of images
Fooling around with a certain bit of relatively recent technology prompted our photographer to ask the question: why are there so many pictures? Our main way of capturing reality, that great manifold of experiences, is still the two-dimensional image. Being a scientist he then sought an answer (where a philosopher might instead have fallen into existential doubt). It’s not so hard to work out, really, but does highlight something important about our memories, and how technology is changing them.
Don’t know much geometry
Why are we forced to learn what we’ll only forget?
While attending to his regular workout in the Five Colors S&T exercise room, our astronomer was reminded of his High School geometry class. (We’ll explain the connection later; it has nothing to do with the angles at which his various muscles were applying force.) Everyone was required to take geometry (and pass it), and most were required to do the same with algebra. Yet it’s a truism that very few people actually use those subjects later on, and most forget them immediately. Why, then, do we bother with teaching and learning them? There are several possible answers, to which we’ll add one of our own.
