The universe is less uniform than we thought—cosmology may need a radical rethink

If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.

Failure Starts Before Overload: USA Roller Chain Publishes Engineering Analysis of Load Distribution in Roller Chain Systems

USA Roller Chain has released a technical analysis examining how internal load distribution governs performance and failure behavior in roller chain systems. The core finding is that most chain ...
