Last week was about catalysts and chemical reactions. This week we are going to reflect on Bernoulli’s principle and pressure. Let’s start with the principle. “In fluid dynamics, Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure (Wikipedia). It’s easy to get lost in that. The essence of this is that Bernoulli’s principle gives you the ability to understand how to manipulate pressure.
One of the most useful applications of Bernoulli’s principle is in aircraft flight. “If the air flowing past the top surface of an aircraft wing is moving faster than the air flowing past the bottom surface, then Bernoulli’s principle implies that the pressure on the surfaces of the wing will be lower above than below. This pressure difference results in an upwards lifting force.” (Wikipedia). A person designing wings for planes needs to understand Bernoulli’s principle, so they can appropriately manipulate and harness the power of pressure. If you don’t harness pressure correctly then a few bad things could happen. For example, the plane never takes off, it comes down too hard, and/or it spirals in the air out of control.
Besides being lost in a nerdtastic rabbit hole, you might be wondering what this has to do with anything. Last time I checked, we don’t design wings for airplanes. At the same time, I’d argue that we are all leaders, and leaders are people who need to understand and harness the power of pressure to lift us to new heights. As leaders, we direct pressure with the expectations we set, how big we dream, and how much we are willing to push each other. Much like an airplane, if we don’t harness the power of pressure correctly bad things can happen. If we don’t do things to create enough positive pressure, then we never create the upward lift that helps people reach their full potential. If we create too much downward pressure, we crush people and keep them from every flying. If we apply uneven pressure throughout the journey we send people spiraling. I know because I’ve had leaders do all of these things, and more importantly I’ve made all those mistakes.
The challenge: How can we harness pressure for positive change?
Have a jolly good day,
