Timbre is caused by the fact that each note from a musical instrument is a complex wave containing more than one frequency.

Norway’s transport minister, Ketil Solvik-Olsen, said that sea currents and underwater topography in the country’s south-western coast “result in particularly complex wave conditions”.

Transportation Minister Ketil Solvik-Olsen had said Wednesday that sea currents and underwater topography in this part of Norway’s southwestern coast “result in particularly complex wave conditions.”

And then there’s quantum physics—the stuff of superposition and complex wave function and the entanglement of particles that even Einstein once referred to as “spooky action at a distance.”

The Sarbanes-Oxley principles are old hat to most boards, but those boards are now struggling with a new and more complex wave of regulatory enforcement.
