Our cleanroom helped us create a platform capable of generating superhydrophilic surfaces using a technique called “liquid dielectrophoresis”. They posted our video on Instagram and, in two days, has over 500k views. Work is supported by @NASAKentucky

@GrumpyReviewer2 @AcademicChatter This happened to me recently. I reviewed a manuscript and told them one of their results was physically impossible and shouldn’t be published in its current form. Well guess what happened…

Why numbers are sometimes better than words.

What people think you say when you say “little chance,” “probably not,” or “highly likely.”

Pebbles that are slightly curved—rather than completely flat—exert the highest impact forces when dropped onto a watery surface. Understanding these forces is important for naval structure design, spacecraft water landing, and Olympic diving injuries. https://t.co/VLTzx6vY4e

Proud of Tommy Bried of @LouisvilleSD and Lakeside for what he’s accomplished at the Olympic trials (picture of our daughters crossing paths with him while hiking at Red River Gorge)

Great work by our @UofLSpeedEng Capstone team! They helped develop an inexpensive system to chill a sample of bourbon (-20C) and measure its turbidity. We plan to use this as a tool to measure “chill haze” that is, hopefully, faster, less expensive, and more accurate.

Did you know that the white and red stripes on a windsock are not for decoration?

They actually indicate precise wind speeds.

Here's how.
