PSI on your homogenizer is a sine wave. Adjust pressure and flow rate to see how cavitation breaks fat globules — the unit circle in your dairy pipe.
The Lab
The Bloop
A sine wave from the bottom of the world. How a 1997 mystery sound connects the unit circle, ocean acoustics, and your homogenizer PSI.
The Lab
Centrifugal Force
Why your centrifuge is just a unit circle. F = mω²r decoded — the butterfat test, RPM to radians, and the trig running your QA protocol since 1890.
The Lab
Microbial Growth Curves
Lag, log, stationary, death — the math of how bacteria grow, why log phase is exponential, and what slow acidification looks like on a curve.
The Lab
Food Safety Math
D-values, Z-values, thermal death time — the logarithms running your pasteurization system. The PMO numbers aren't arbitrary. They're math.
The Lab
Science of the Octagon
The same math behind a centrifuge spin and a spinning kick. Angular velocity, vector strikes, energy systems, and momentum — with the lactate-to-yogurt connection.
