  -== Biological Considerations
  -
  -* Metabolic activity does not significantly raise the temperature of the cell (right?)
  -* ATP, the main energy source of metabolism, has energy \(E_\mathrm{ATP} \sim 20 k_B T\)
  -* Metabolic activity would not have a rotational orientation
  +*** \(\vec \Gamma_T\) for the thermostat; balanced by \(\gamma\)
  +*** \(\vec \Gamma_k\) for metabolism
   
   == Random Kicks
   
  -* The thermostat gives random kicks, \(\Gamma_T \sim \Delta t k_B T \sim {10}^{-5} k_B T\)
  -
  -* Metabolism kicks are \(0 \le E_k \le 20 k_B T\), instantaneous, and uncorrelated

positive.code: * \(f\) is the kick _frequency_, _T_ is the measured _temperature_
  * Kicks that are too frequent raise the temperature

  == Studying Active Matter
  
  [discrete]
  ==== *Active Matter* is composed of self-driven units, active particles, each capable of converting stored or ambient free energy into systematic movement [cite:marchetti_hydrodynamics_2013]
  
  * Active matter is an active field of research
  
  * Much of it is concerned with studying bird flocks, fish schools, and bacterial swarms, but occasionally considers non-living particles
  
  * Most studies use *responsive* and/or *directed* particles
