Just an explanation of what convection is as regards to air circulation. Have you ever been in a situation where someone might have gone off and done something based on something that had been taken to be applied in a very narrow context without keeping in mind the wider picture? I couldn't find any pictures that were neutral so I won't use any although it would have been much easier to grasp as a concept with a visual aid. I'm not too into encouraging dispute.

This is NOT to be applied in any way through some individual or group interpretation for direction on how things should go within a relationship or affect how people should interact in some over arching application since human interaction is not bound by many of the more simplistic universal laws that govern particular facets of classic scientific principal. Although granted at times human behavior can have some very predictable facets to it with any in depth knowledge but not anywhere near anything as simplistic. Human behavioral complexities are not the things that these laws in isolation fundamentally govern although they may be essential to creating the environment in which humans thrive. Nor would we have been able to make choices or master our environment as we have within the thresholds we find acceptable relative to our wants and needs dictated by things we consider to be important to us through choices.

For example, a tree is just a tree. It can't decide to go to some place warmer when it gets a bit cold. Nor can it decide to build a house or look for shelter. It can't suddenly decide to move if say it knew the chances of being struck by lightning are pretty high where it lives, or maybe in the event of a forest fire it can't decide to run to avoid it. In fact a single tree obviously has no active consciousness to think or feel on the same level of complexity as human beings for that matter.

This is certainly not to be applied in any such way within isolation unless you have a broader knowledge of all the other principles and wider contexts within which it is all happening to know that it may be applicable to any given situation.

I guess many base scientific principles could call on the catchphrase "it just works" as the results you'd want would and should always be predictably the same under the exact same conditions. Also science has to be based on facts and truth for it to work, make new discoveries and nurture new developments.





Convection

The reason why hot air is less dense (thus making it less heavy) is that the air particles within hot air are vibrating much more then particles in cold air. The more the air particles vibrate the more they bump into each other and push each other apart creating more space between the particles which causes the air to become less dense.

The particles get the energy they need to vibrate from heat energy.

The particles in cold air are vibrating much less and aren't pushing each other apart. This causes the air particles within cold air to be packed much closer together which makes cold air denser (thus heavier due to the effects of earth’s gravity on mass).

So as warmer air rises the cooler air will fall and as the cooler air warms up again it will rise as the warmer air cools and falls again. This continues within a circular cycle to cause the distributing of heat say within an enclosed space such as a room with a heater.

At the very least I would hope somebody out there that might be trippin' or wired on disco biscuits who might not be too familiar with this concept but maybe has a relatively good grasp of science might be able to come up with something contributionally constructive through some kind of out of the box perspective that we might have over looked. It might give insight into other things relating to some other kinds of scientific ideas we might not have yet explored too. Maybe even possibly on the slimmest chance you might have gotten some kind of inspiration from it for things that have nothing to do with science at all.
