Why parasitic currents can paralyze trains and what roller bearings have to do with it: read all about it here.

Perfectly shaped steel spheres as rolling elements in bearings exhibit variances only in the micrometer range: a manufacturing technology feat whose invention dates back 140 years in 2023.

You can rarely see them, practically never hear them but whenever something is moving in the world, chances are that a bearing is involved. A time journey tracing the history of hidden talents.
