## Description

The first part (around 1/3) of the module deals with (biological) processes whose time evolution is described by an exponential law (growth or decay).

Radioactivity will be discussed, as an illustration of such a process, and for its applications in the biology-health-environment field (dating, tracing, etc.).

The second part (around 2/3) of the module introduces the concepts of fluid and pressure, and presents the laws of hydrostatics (fundamental law of fluid statics, Archimedes' theorem).

Fluid dynamics will be introduced, including the concepts of flow, viscosity, sedimentation and centrifugation, in connection with the Biology-Health sector.

List of Chapters :

- Exponential variations

- Radioactivity (radioactive decay, activity)

- Fluids: definition, properties, notion of pressure

- Hydrostatics: fundamental law of fluid statics, Archimedes' theorem.

- Elements of hydrodynamics: flows, Bernouilli's theorem

- Viscosity; Sedimentation and centrifugation
