I think I overspecified the problem. I'm looking for ways to deal with maximum ignorance, because if you can deal with ignorance of the outside that means you have achieved independence. Dependencies specification is so popular today and I want something quite the opposite. There's bloat of dependencies, but there's bloat in independence as well. How would you deal with the bloat of independence?
I guess it's not even real world physics. And the Newton you attribute those formulas to is not real world Newton. For alternative world, your physics are just perfect. For real world, you need to factor in time as well as space.
Seriously, login is not the place to be helpful. On the contrary, for security reasons, the login control should be hard to find, and the error messages should be cryptic, like "ehh". You can reward their patience on the other side.
Sorry for delayed reply. I think so because JavaScript, with its prototype system, dynamic typing and closures, makes various famous language features and their implementations explicit, while other languages may hide their inner workings in the name of simplicity, safety, etc. Thus, by learning JavaScript first, one can bypass the reverence for OOishness espoused by Java or C#, and yet understand them better because "class", "type", "object" in JavaScript understood to be not atomic concepts, but constructable pieces of code. With JavaScript, one starts interacting with inner workings of the language very early in the learning process. Really, in which language one learns about events first? Remember "onClick"? Sure, interaction starts at level 0, but that's great because already the value of events is understood without writing a single "public static main voiid".
I've seen it on many free download sites (not that I visited any of them). You click to download a file (enticing!), and you get a splash page of many questionable ads. I'm sure there is some cost sharing involved.
I've been programming for probably 17 years, since high school, and just recently I appreciated JavaScript. For all its shortcomings, it's beautiful. If you'd just understand it, you would be able to easily understand other languages, dynamic or otherwise.
