Air Pressure and Generating Lift

“For He looks to the ends of the earth, and sees under the whole heavens, to establish a weight (pressure) for the wind, and apportion the waters by measure.” – Job 28: 24 – 25

1. In 1643, an Italian scientist by the name of Evangelista Torricelli invented the barometer

  • The barometer is a device that enables atmospheric pressure to be measured
  • “Atmospheric pressure is caused by the weight of the atmosphere pushing down on itself and on the surface below it. Pressure is defined as the force acting on an object divided by the area upon which the force is acting.” 1
  • At sea level, atmospheric pressure is equivalent to 14.7 pounds per square inch 2

2. Torricelli was also the first scientist to provide an explanation for the cause of wind:

  • “Winds are produced by differences of air temperature, and hence density, between two regions of the earth” 3

3. Isn’t it interesting that Job is penning the words to these verses more than 3,600 years earlier than Torricelli’s invention?

  • Job is recognizing that wind (moving air) has mass
  • It is this innate property of air to have mass that enables a force called ‘lift’ to be create
  • Its ‘lift’ and harnessing this ability to create force, that is the basis for all air flight

4. The Bible is accurate in its aerodynamics and by extension, its aeronautics
