Thinking in stories
The limits of doing your science in metaphors
It’s vital not to confuse an illuminating explanation of science with the science itself.
Scientists and doublethink
Using different theories at the same time
Scientists, especially astronomers, use several incompatible theories in their calculations. How? And why?
When science is an art
The experimentalist’s skill
Some scientists have an unusual skill for extracting precise data from their instruments. Sometimes this leads others to question their results.
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.
Brass, glass and verniers
Scientists of yesterday were different
Our astronomer and our navigator are away from headquarters at the moment, showing a Professor of Physics how to use his sextant. This style of instrument was the mainstay of nineteenth-century astronomy: made of brass and glass, with precise scales engraved on them for careful measurements. The people who used them had to work in a different way from current astronomers and must have had a different approach to life.
The unnecessary theory
You will have heard of the detection of gravitational waves, just announced this past week. For once the mass media haven’t over-hyped a scientific discovery: this really is an important find. We’re not going to try to explain the science behind it (there are lots of articles on line and offline that do that). It’s the fact of the 100-year gap between the theoretical prediction and the actual observation that tells us something about the nature of science.
Getting your universe right

The strange case of the dimming star
A good and bad example of current science
Our astronomer begs to be allowed to explain what’s really interesting about KIC8462852.
In the eye’s mind
What you see depends on what you’re looking for
Our photographic consultant is fond of pointing out to us, with the help of books and magazines, the different styles of great photographers. Clearly part of the variation in the final image is in the subjects they choose: Ansel Adams is famous for mountains and landscapes of the Southwest, quite a different thing from a New York City street photographer catching an instant among people. “But,” he says, “put in exactly the same place, facing exactly the same subject, they’d still come up with different pictures. They just see differently.” Which is true, and much more widely applicable than he meant. Even the same person looking at the same scene can see something entirely different at a different time. A simple exercise can show this.
