No, not a scientific understanding of the process by which chemical energy is converted to mechanical energy, or even the demanding study of fuel efficiency, or much less the historical evolution of engines from the time of the Aeolipile But, as with any mental evolution, many tangential areas of study need to be considered for both the wholistic and practical application of said knowledge. The first course of study for any "would be" motor vehicle operator is the fundamental forces of classical physics that effect ALL bodies in motion -- acceleration, velocity, inertia, blah-blah-blah, but, more importantly, how these forces are amplified to extreme danger during the operation of a motor vehicle. Secondly even though a student of "motorized locomotion" need not understand the inner workings of an internal combustion engine, he would behoove himself to study some basic and practical knowledge of the generalized system. 1. A modern motor vehicle converts chemical energy stored in fuel into mechanical energy via and internal explosion. The major components of a modern motor vehicle include: Engine, Transmission and Drive-train -- Nuff said. 2. Mechanical components require fluids to reduce friction and remove heat from the system, therefore, a working knowledge of fluid levels and locations is vital. Furthermore, fluids are color coded. Oil is black; most transmission fluids are red; coolant is colored yellow (or green) and mixed with water. **As a side note, you might want to be aware that ethylene glycol, whilst quite poisonous, tastes sweet. That fact may seem inconsequential until your beloved pet drinks leaking coolant water, quickly goes blind, and dies a slow horrible death. 3. Vehicles require lights and signals for safety and useability. An understanding of the proper locations and procedures for periodic testing is vital to safe operation. Same for other safety devises and interfaces. 4. Obviously some rules of the road are applicable. Your car will not be the ONLY vehicle on the road, therefor your must understand how to interface with other drivers, navigate adverse road conditions, and react to unexpected situations that can arise at any time. ============================================================ Conclusion: ============================================================ The main points i outlined are merely a blip on the radar of the many tangential points of study, however, they are quite relevant to proper operation of a motor vehicle. Most of you can probably draw the parallels to programming from these examples. My opinion is that problem solving should be covered before any language is even discussed or any code is written. Too many people lack basic problem solving skills. Look, if you can't write up (or imagine) the "general" steps that are required to solve your problem, then how the heck do you expect to write code to solve the problem? And let's just get one thing strait from day uno for all you "perspective programmers" out there: If the idea of banging your head on a desk for days only to find out that some stupid API does not work as expected, or was poorly designed, or that, GOD FORBID... you made the dumbest mistake ever! Ha Ha Ha! If the idea of that kind of mind numbing detective work is not fun for you, well, you're in good company because i don't always enjoy it either... HOWEVER! if you're not driven by the satisfaction of finding the answer; by a burning desire to solve the problem; by an unflinching will not to be defeated by any bug -- because the answer is always out there, you just have to find it -- well then, programming might not be for you. But i'm just wasting my time because soon you'll discover Python list and Stack overflow and from these sources flows an endless supply of free labor. Teach a man to Google and others program for a day. Teach him to problem solve, and he programs for life. -- https://mail.python.org/mailman/listinfo/python-list
