The evil test: 1. Evil tests create a lock on how the code is implemented. 2. Cause duplication. 3. Builds uncertainty on the tests (red is meaningless). 4. Decrease productivity. 5.

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
