Thermo, as we called it, was the most abstract class that I have ever had the pleasure of taking during engineering college.
The class made no sense to me at all in it’s practicality of normal daily USAge or necessity.
When on earth do I ever need to recognize the second law of thermodynamics? It hasn’t come up yet so far in the 30 years since I have taken the class, & I’m going to go out on a limb & say that I entirely won’t need it for the next 30 years either. It’s right there with Differential Equations. How much do we really need to recognize about heating & cooling of closed loop systems, along with entropy & extropy? I would have much better spent my time getting an Heating & A/C license or even starting my own commercial Heating & A/C supplier with all of the time I spent studying Thermo. I suppose we don’t recognize when we are that age, & need the course to get our degree anyways, that we really won’t use the course again after we get our grades. I wish I did get my Heating & A/C certification now because I suppose my cooling system condenser is bad & needs to be replaced. I don’t suppose it is a truly cheap task either so I may be spending a lot of cash on getting it replaced. Maybe I should get my Heating & A/C licence & do it myself. I’m just thinking out loud here & trying to come up with a solution. Besides, how much does a new heating & cooling idea cost?
