A Journey Through Nonlinear Dynamics: The Case of Temperature Gradients

The overall effect of temperature gradients is stressed for the Earth's core and surface, but also Sun's surface. Using Rayleigh–Bénard convection in helium mercury, we measured all scaling properties period-doubling cascade quasiperiodicity. Hard turbulence are presented an experiment using gas at low temperature. A [Formula: see text] law exponential distribution fluctuations observed. We present a study cell with open top floater. One simplest limit cycles observed floater position. It follows model proposed by Wilson continent motion. Soret effect, how differences lead to strong accumulation DNA suspensions. Also polyethylene glycol concentration gradients, local RNA accumulation. Finally, thermal convection, build one smallest PCR machines.
