The temperature-driven change in the mobility of water molecules on the surface perfectly matches how ice’s friction coefficient changes with temperature — the more mobility at the surface, the lower the friction. - https://www.zmescience.com/science/ice-slippery-h-bonds-8731058/ “As the physicist Richard Feynman predicted, the solution was not to be found in new equations, but rather within the equation that was already available to us,” explained Tobias Schneider, author of the new study. “Until now, researchers didn’t have powerful enough mathematical tools to verify this.”- https://www.zmescience.com[..]ws-science/turbulent-fluid-flow-28052019

This deliberate self-reflection – taken from a distanced perspective, when we are in a more rational frame of mind – reminds us that some things will be out of our control, and need not be the source of upset. At the same time it helps us to navigate the challenges that are within our control more wisely, so that we don’t just make the same mistakes again and again. - http://www.bbc.com[..]190605-a-mentalists-guide-to-being-happy
