i delight in buoyancy




In sciencebuoyancy /ˈbɔɪ.ənsi/ is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards. The magnitude of that force is proportional to the difference in the pressure between the top and the bottom of the column, and (as explained by Archimedes' principle) is also equivalent to the weight of the fluid that would otherwise occupy the column, i.e. the displaced fluid. For this reason, an object whose density is greater than that of the fluid in which it is submerged tends to sink. If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. This can occur only in a reference frame which either has a gravitational field or is accelerating due to a force other than gravity defining a "downward" direction (that is, a non-inertial reference frame). In a situation of fluid statics, the net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body.[1]

Thank you Wikipedia.

My knowledge of buoyancy is minimal. Let's be honest, physics was not a strong suit for me, but better than calculus so....I don't know what that says.

What I do know is that physical laws that govern the earth (e.g., gravity, buoyancy, etc) can have some parallels to life. Or at least I like to pretend that the do. For example...

For the principle of buoyancy to work there has to be a weight that causes an object to become immersed. So, if I am the boat then the weight in my boat could be a compilation of my callings in life (e.g., sister, daughter, friend, daughter of god, lover of children) and subsequently the things associated with carrying out these roles. That list varies at times depending on the weight of particular roles but nevertheless, there are always things to be done, people to be loved and lessons to learn. These weights at times can be significant.

So what is it that keeps us afloat? What is it that keeps us from sinking? Well, if our density is greater than that of the fluid it is submerged in, it sinks...so it has to be less dense than the liquid. The difference in that pressure results in a force that drives the object upward. And so...upward we go, and upward we want to be (I don't want to rot on the bottom of the ocean floor).

Our fluid has to have some weight to it. To me, the fluid is the gospel. We can go through the motions, we can appear to be on track and on target, but it doesn't mean that we always are. We must be watching ourselves because we are the ones who really know the condition of our hearts. It is the gospel which bears me up. It is knowing that I am not the only one with this load to carry but that the Savior is right there willing to help me all the way. It is knowing that when I put first things first, everything else falls into place. It is knowing and seeing how he helps me to put first things first.

While I'm sure some physicist would look at this analogy and say, this girl doesn't know physics at all, well that's okay because I don't profess to...but I could teach you how to say your /r/.  :)  What I'm really saying here is that we have to make sure there are active forces in our lives driving us upward, preventing us from sinking.

There will be and are times when we begin to sink. When the weight gets too much to bear. It is no coincidence that we have a "saver" or at least a Savior. He will help us carry the burdens which are placed upon our backs. He will help us make it back.
