This article is about using science in the medical field for artificial respiration. It looks at the body's ability to adapt to recurring stimuli. New respirators are being developed with this newly aquired information that could minimize the need for sedation or paralysis currently necessary for some patients on mechanical ventilation.

Velocity vs. Acceleration

Velocity is the rate and direction of the change in the position of an object.
ie. A car going down a curvy road at 50 mph experiences a chaning velocity as it goes from one turn to the next.



Acceleration is is the rate of change of velocity with time.
ie. A car only experiences acceleration when it starts moving from a stop. The same car going down the curvy road at a constant speed of 50 mph experiences no change in acceleration.

Scientific Method

These are the steps in the Scientific Method
  1. Recognize a problem
  2. Make an educated hypothesis about the answer
  3. predict the consequences of the hypothesis.
  4. Preform experiments to test prediction.
  5. formulate the simplest general rule that organizes the three main ingredients: Hypothesis, prediction, and experimental outcome.
