Why do some bearings look shiny with wear?
April 25, 2023We tend to think of “new” surfaces as shiny and smooth, and “worn” surfaces as rough, dull, or uneven. But for a bearing surface, the opposite is often true: the
Visualizing “filtering” — an animation
April 18, 2023Surface texture can be described as a spectrum of spatial wavelengths. “Filtering” is the process to isolate the wavelengths that matter for our application. But what does that really look
A plant with self-cleaning leaves?
March 29, 2023A lot of effort goes into creating materials that can resist sticking, repel water, or keep oils off of cell phone screens. But some plants are able to accomplish tasks
Paint finish and spatial wavelengths
March 14, 2023Two lots of steel pass inspection for surface roughness. Yet, when we paint a panel from each lot, one looks great, and the other…does not. How can it be, when
How do I calibrate my fingernail?
February 28, 2023Tactile gages (comparator strips) can aid in quick assessment of a process, but they have limitations for process control. We look at their strengths and weaknesses in this blog post.

Curling again! Applying the lessons of micro-texture to the macro texture of curling ice
January 23, 2023We’ve had a lot going on related to ice lately! It is that time of year… A few months ago, we posted an article about the sport of curling, which
Ice and friction – there’s a lot going on!
January 19, 2023Want to maximize your fun while skating? Make sure that the ice temperature is -7°C! For many years I thought that concentrated pressure is what melts the ice when you
