It is a variable star of low amplitude, and is 700 times the size of our Sun.
He states "the box" is not just a metaphor-it is real, a low amplitude.
On the other hand, "in the box thinking" (a low amplitude) is not detrimental.
Instead, they are waves with high amplitude at one point and much lower amplitudes on either side of that highest peak.
The Sun oscillates with very low amplitude in a large number of modes having periods around 5 minutes.
It is a fair approximation for higher intensities, but not for lower amplitudes.
These low amplitude propagated contractions are reported to be more frequent.
This means that a more stable ship will generally have higher accelerations but lower amplitudes of motion.
Seismic noise has very low amplitude and cannot be felt by humans.
Note the lower amplitude for the shorter periods.
