Take the Poll: Color Schemes in Presentations

In Eloquent Science (p. 279), I made the argument that light-colored text on dark-colored backgrounds was preferable to dark-colored text on light-colored backgrounds for three reasons. 1. Red lasers (especially if the laser light is weak) may not show up well on white backgrounds. 2. Slides with white backgrounds lose contrast if the room is … read more

Why I don’t make copies of my slides available

As I describe in the Preface to Eloquent Science, the book arose out of a workshop that I taught to undergraduates in Oklahoma. The workshop arose over six years, with what were essentially my lecture notes on PowerPoint slides. The slides were wordy and boring. During the talk, the students had paper copies of my … read more

What are your pet peeves?

Appendix B: Commonly Misused Scientific Words and Expressions of Eloquent Science was inspired by a list of incorrect science expressions and annoyances maintained by Chuck Doswell. Many of Chuck’s pet peeves are included in Appendix B. I also surveyed my friends and colleagues about their pet peeves and included many of them in Appendix B. … read more

Positive and negative feedback in science: Scientists as social animals

At a recent meeting at the University of Manchester, the keynote speaker was Prof. Helen Gleeson OBE. She gave an informative and interesting history of her career and the lessons she has learned. One thing she said resonated with me (paraphrasing): “As a scientist, you get lots of rejections, but not a lot of supportive … read more

“PowerPoint makes us stupid.”

This story is from The New York Times about how PowerPoint has been used (or banned, in some cases) from military meetings and briefings. “We have met the enemy and he is PowerPoint.”

Proper spellings of atmospheric science words

Did you know that shortwave radiation is not hyphenated, but short-wave trough is? Did you know that air mass is two words when used as a noun, but one word when used as an adjective (e.g., airmass modification)? If you are ever wondering how scientific words are spelled or used, the American Meteorological Society has … read more

A figure in need of help

I ran across this figure from an American Meteorological Society journal article recently. It’s just a simple scatterplot, which is so easy to construct, yet this figure has so many problems. 1. False alarm ratio and probability of detection are both quantities that can have values between 0 and 1, but the x axis ranges … read more

Whether to use colons in titles

In Eloquent Science, I discuss my thoughts about colons in titles of scientific articles on pp. 24-25, but only briefly. Dave Mechem (University of Kansas) emailed me to express concern about their overuse in some disciplines like geography, humanities, and some of the social sciences. For an example, take a look at this issue of … read more

Prof. Rob Fovell (UCLA) on PowerPoint and Teaching

I do not use PowerPoint in class. PowerPoint is virtually a necessity for scientific talks, but I think they often hurt classroom lectures. They lock me into a particular order, and they tend to make me go through material too fast. My handwriting is poor, but I write in class so I don’t go too … read more
