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 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

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

Correct use of the Kelvin temperature scale

Prof. Terence Day at Okanagan College, British Columbia, recently wrote an article describing the errors in textbooks. He argues that, “If the discipline of physical geography is a genuine natural science then the internationally recognized scientific units must be correctly used.” The issue is the Kelvin temperature scale. At the General Conference on Weights and … read more

Appropriate way to label axes of graphs

Prof. Brian Fiedler of the University of Oklahoma recently published an article in Physics Education calling for a change in direction in teaching dimensionless ratios in physics. As he advocates, The tick marks [on an axis of a graph] are pure numbers. Labels with a solidus such as R/µm are orthodox notation for what the … read more
