The Code is the Design

Background As a former regular biker myself, the term super-bike always seemed a bit hyped. Had two 10-12 BHP bikes for 10 years, a ~15 BHP bike for 6 years, a 25 BHP bike for 9 years, and now a 47 BHP bike for the last 3 years. The last two actually had plenty of power for any kind of city usage, and most highway usage as well. But after having finally moved to a 200+ BHP super-bike after 30 years of biking , one has to admit that there are significant differences in the categories. It's simply not the same kind of machine. It's not even the same world! And I've barely even scratched the surface of what this bike can do. First Week Break-In First of all, here are my personal notes from the first week of a complete by-the-book break-in. BTW, that is something I've done for all five new bikes I've had. Regardless of whether the bikes need it anymore, I believe the riders still do.  That would also explain why even bikes that cost as much as several cars are still ...

A popular meme online shows the below self-closing lid on a Japanese brand Jam Jar. Some online users have suggested temperature differentials and resulting pressure differentials as the possible cause. But no one really seems to know why. But such an effect could easily be achieved with a frictionless coating such as the one below, which are becoming increasingly common. After all, the only thing that normally prevents gravity from pulling the lid down is friction between Lid and Jar. The inertial resistance would be minimal, both vertical and rotational. The problem is simply a variation of the frictionless nut question , a vertical acceleration causing a rotational acceleration and vice versa.
