High-speed imaging reveals that the squeak of soft–rigid frictional interfaces, like sneakers sliding on a basketball court, arises from intersonic opening slip pulses—analogous to earthquake ruptures—that thin ridges on the rubber confine to repeat at a musical frequency.

As a side sleeper, I went out and tried a few knee pillows designed for side sleepers with my original, crappy foam mattress I've been sleeping on for the past five years. Mackey wasn't kidding—it did help. I was more comfortable and fell asleep faster. I liked both the Pillow Cube Knee Cube (which is discontinued) and the Everlasting Comfort Knee Pillow ($34) for different reasons. The Everlasting has a strap to keep it in place, but it's nice and small if you don't want something as bulky as the Pillow Cube in your bed. I did find that the smaller Everlasting was more likely to end up on the floor, though, versus the Pillow Cube's being easier to relocate and tuck back into my knees in the middle of the night. Both helped with my spinal alignment and reduced my back pain a bit, but I still found switching to a more supportive mattress to be a bigger improvement.
Yeah, that's why I'm posting this on my personal blog and not on a dedicated alternate history website, they'd tear me apart.
